However, multi-species monitoring using call-broadcast may reduce these benefits if birds are reluctant to call once they hear broadcasted calls of other species. We compared a protocol that uses call-broadcast for only one species (Yuma clapper rail [Rallus longirostris yumanensis]) to a protocol that uses call-broadcast for multiple species. We detected more of each of the following species using the multi-species protocol: 25 % more pied-billed grebes, 160 % more American bitterns, 52 % more least bitterns, 388 % more California black rails, 12 % more Yuma clapper rails, 156 % more Virginia rails, 214 % more soras, and 19 % more common gallinules. Moreover, the coefficient of variation was smaller when using the multi-species protocol: 10 % smaller for pied-billed grebes, 38 % smaller for American bitterns, 19 % smaller for least bitterns, 55 % smaller for California black rails, 5 % smaller for Yuma clapper rails, 38 % smaller for Virginia rails, 44 % smaller for soras, and 8 % smaller for common gallinules. Our results suggest that multi-species monitoring approaches may be more effective and more efficient than single-species approaches even when using call-broadcast.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wetlands","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","doi":"10.1007/s13157-013-0425-x","usgsCitation":"Nadeau, C.P., Conway, C.J., Piest, L., and Burger, W.P., 2013, Multi-species call-broadcast improved detection of endangered Yuma clapper rail compared to single-species call-broadcast: Wetlands, v. 33, no. 4, p. 699-706, https://doi.org/10.1007/s13157-013-0425-x.","productDescription":"8 p.","startPage":"699","endPage":"706","ipdsId":"IP-036080","costCenters":[{"id":127,"text":"Arizona Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"links":[{"id":273626,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":273625,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s13157-013-0425-x"}],"volume":"33","issue":"4","noUsgsAuthors":false,"publicationDate":"2013-05-10","publicationStatus":"PW","scienceBaseUri":"51b838dce4b03203c522b196","contributors":{"authors":[{"text":"Nadeau, Christopher P.","contributorId":105956,"corporation":false,"usgs":true,"family":"Nadeau","given":"Christopher","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":467767,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Conway, Courtney J. 0000-0003-0492-2953 cconway@usgs.gov","orcid":"https://orcid.org/0000-0003-0492-2953","contributorId":2951,"corporation":false,"usgs":true,"family":"Conway","given":"Courtney","email":"cconway@usgs.gov","middleInitial":"J.","affiliations":[{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true}],"preferred":true,"id":467764,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Piest, Linden","contributorId":104797,"corporation":false,"usgs":true,"family":"Piest","given":"Linden","email":"","affiliations":[],"preferred":false,"id":467766,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Burger, William P.","contributorId":54872,"corporation":false,"usgs":true,"family":"Burger","given":"William","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":467765,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

We conducted a spatial analysis of point patterns using Canada goose nest locations and nest fate, and lesser snow goose nest locations at two study areas in northern Manitoba with different densities and temporal durations of sympatric nesting Canada and lesser snow geese. Specifically, we assessed (1) whether Canada geese exhibited territoriality and at what scale and nest density; and (2) whether spatial patterns of Canada goose nest fate were associated with the density of nesting lesser snow geese as predicted by the protective-association hypothesis. Between 2001 and 2007, our data suggest that Canada geese were territorial at the scale of nearest neighbors, but were aggregated when considering overall density of conspecifics at slightly broader spatial scales. The spatial distribution of nest fates indicated that lesser snow goose nest proximity and density likely influence Canada goose nest fate. Our analyses of spatial point patterns suggested that continued changes in the distribution and abundance of breeding lesser snow geese on the Hudson Bay Lowlands may have impacts on the reproductive performance of Canada geese, and subsequently the spatial distribution of Canada goose nests.</span></p>","language":"English","publisher":"Public Library of Science","doi":"10.1371/journal.pone.0081029","usgsCitation":"Reiter, M., and Andersen, D., 2013, Evidence of territoriality and species interactions from spatial point-pattern analyses of subarctic-nesting geese: PLoS ONE, v. 8, no. 12, Article e81029: 10 p., https://doi.org/10.1371/journal.pone.0081029.","productDescription":"Article e81029: 10 p.","ipdsId":"IP-017802","costCenters":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"links":[{"id":473757,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1371/journal.pone.0081029","text":"Publisher Index Page"},{"id":344978,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"8","issue":"12","publishingServiceCenter":{"id":9,"text":"Reston PSC"},"noUsgsAuthors":false,"publicationDate":"2013-12-02","publicationStatus":"PW","scienceBaseUri":"599a9fb6e4b0b589267d58b9","contributors":{"authors":[{"text":"Reiter, Matthew","contributorId":195769,"corporation":false,"usgs":false,"family":"Reiter","given":"Matthew","email":"","affiliations":[{"id":17734,"text":"Point Blue Conservation Science","active":true,"usgs":false}],"preferred":true,"id":708098,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Andersen, David E. 0000-0001-9535-3404 dea@usgs.gov","orcid":"https://orcid.org/0000-0001-9535-3404","contributorId":2168,"corporation":false,"usgs":true,"family":"Andersen","given":"David E.","email":"dea@usgs.gov","affiliations":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true},{"id":34539,"text":"Minnesota Cooperative Fish and Wildlife Research Unit","active":true,"usgs":false}],"preferred":true,"id":708019,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Pre-emission capture and storage of CO<sub>2</sub> in subsurface saline formations is one potential method to reduce greenhouse gas emissions and the negative impact of global climate change. Like many large-scale resource assessments, the area under investigation is split into smaller, more manageable storage assessment units (SAUs), which must be aggregated with correctly propagated uncertainty to the basin, regional, and national scales. The aggregation methodology requires two types of data: marginal probability distributions of storage resource for each SAU, and a correlation matrix obtained by expert elicitation describing interdependencies between pairs of SAUs. Dependencies arise because geologic analogs, assessment methods, and assessors often overlap. The correlation matrix is used to induce rank correlation, using a Cholesky decomposition, among the empirical marginal distributions representing individually assessed SAUs. This manuscript presents a probabilistic aggregation method tailored to the correlations and dependencies inherent to a CO<sub>2</sub> storage assessment. Aggregation results must be presented at the basin, regional, and national scales. A single stage approach, in which one large correlation matrix is defined and subsets are used for different scales, is compared to a multiple stage approach, in which new correlation matrices are created to aggregate intermediate results. Although the single-stage approach requires determination of significantly more correlation coefficients, it captures geologic dependencies among similar units in different basins and it is less sensitive to fluctuations in low correlation coefficients than the multiple stage approach. Thus, subsets of one single-stage correlation matrix are used to aggregate to basin, regional, and national scales.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Stochastic Environmental Research and Risk Assessment","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","doi":"10.1007/s00477-013-0718-x","usgsCitation":"Blondes, M., Schuenemeyer, J.H., Olea, R., and Drew, L.J., 2013, Aggregation of carbon dioxide sequestration storage assessment units: Stochastic Environmental Research and Risk Assessment, v. 27, no. 8, p. 1839-1859, https://doi.org/10.1007/s00477-013-0718-x.","productDescription":"21 p.","startPage":"1839","endPage":"1859","ipdsId":"IP-037774","costCenters":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":273553,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":273548,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s00477-013-0718-x"}],"volume":"27","issue":"8","noUsgsAuthors":false,"publicationDate":"2013-05-18","publicationStatus":"PW","scienceBaseUri":"51b6e758e4b0097a7158ab39","contributors":{"authors":[{"text":"Blondes, Madalyn S. 0000-0003-0320-0107 mblondes@usgs.gov","orcid":"https://orcid.org/0000-0003-0320-0107","contributorId":3598,"corporation":false,"usgs":true,"family":"Blondes","given":"Madalyn S.","email":"mblondes@usgs.gov","affiliations":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":474316,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schuenemeyer, John H.","contributorId":54227,"corporation":false,"usgs":true,"family":"Schuenemeyer","given":"John","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":474318,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Olea, Ricardo A. 0000-0003-4308-0808","orcid":"https://orcid.org/0000-0003-4308-0808","contributorId":47873,"corporation":false,"usgs":true,"family":"Olea","given":"Ricardo A.","affiliations":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"preferred":false,"id":474317,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Drew, Lawrence J. ldrew@usgs.gov","contributorId":2635,"corporation":false,"usgs":true,"family":"Drew","given":"Lawrence","email":"ldrew@usgs.gov","middleInitial":"J.","affiliations":[{"id":245,"text":"Eastern Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":false,"id":474315,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

However, important features of individual immune responses, such as the strength and longevity of immunity, can be challenging to characterize, particularly if they cannot be replicated or controlled in captive environments. Our research on bighorn sheep pneumonia elucidates how individual bighorn sheep respond to infection with pneumonia pathogens by examining the relationship between exposure history and survival in situ. Pneumonia is a poorly understood disease that has impeded the recovery of bighorn sheep (Ovis canadensis) following their widespread extirpation in the 1900s. We analyzed the effects of pneumonia-exposure history on survival of 388 radio-collared adults and 753 ewe-lamb pairs. Results from Cox proportional hazards models suggested that surviving ewes develop protective immunity after exposure, but previous exposure in ewes does not protect their lambs during pneumonia outbreaks. Paradoxically, multiple exposures of ewes to pneumonia were associated with diminished survival of their offspring during pneumonia outbreaks. Although there was support for waning and boosting immunity in ewes, models with consistent immunizing exposure were similarly supported. Translocated animals that had not previously been exposed were more likely to die of pneumonia than residents. These results suggest that pneumonia in bighorn sheep can lead to aging populations of immune adults with limited recruitment. Recovery is unlikely to be enhanced by translocating nai¨ve healthy animals into or near populations infected with pneumonia pathogens.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"PLoS ONE","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"PLoS","doi":"10.1371/journal.pone.0061919","usgsCitation":"Plowright, R., Manlove, K., Cassirer, E.F., Besser, T.H., and Hudson, P., 2013, Use of exposure history to identify patterns of immunity to pneumonia in bighorn sheep (Ovis canadensis): PLoS ONE, v. 8, no. 4, 12 p., https://doi.org/10.1371/journal.pone.0061919.","productDescription":"12 p.","numberOfPages":"12","onlineOnly":"Y","additionalOnlineFiles":"Y","ipdsId":"IP-041146","costCenters":[{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"links":[{"id":473763,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1371/journal.pone.0061919","text":"Publisher Index Page"},{"id":273480,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":273479,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1371/journal.pone.0061919"}],"country":"United States","state":"Idaho","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -116.9495,44.0718 ], [ -116.9495,46.6117 ], [ -115.3125,46.6117 ], [ -115.3125,44.0718 ], [ -116.9495,44.0718 ] ] ] } } ] }","volume":"8","issue":"4","noUsgsAuthors":false,"publicationDate":"2013-04-26","publicationStatus":"PW","scienceBaseUri":"51b6e75de4b0097a7158ab75","contributors":{"authors":[{"text":"Plowright, Raina K.","contributorId":23038,"corporation":false,"usgs":true,"family":"Plowright","given":"Raina K.","affiliations":[],"preferred":false,"id":479487,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Manlove, Kezia","contributorId":68204,"corporation":false,"usgs":true,"family":"Manlove","given":"Kezia","affiliations":[],"preferred":false,"id":479489,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Cassirer, E.

The program consists of detailed maps of all Sonoran Desert perennial plants in 30 permanent plots located on Tumamoc Hill, near Tucson, Arizona, USA. Most of these plots are 10 m × 10 m quadrats that were established by Volney Spalding and Forrest Shreve between 1906 and 1928. Analyses derived from these data have been pivotal in testing early theories on plant community succession, plant life history traits, plant longevity, and population dynamics. One of the major contributions of this data set is the species-specific demographic traits that derived from estimating individual plant trajectories for more than 106 years. Further use of these data might shed light on spatially explicit population and community dynamics, as well as long-term changes attributable to global change.\n\nData presented here consist of digital versions of original maps created between 1906 and 1984 and digital data from recent censuses between 1993 and 2012. Attributes associated with these maps include location and coverage of all shrubs, and in some cases, plant height. In addition, we present plot-specific summaries of plant cover and density for each census year and all other information collected, including seedling counts, grass coverage, and annual species enumerations. We reference the repeat photography of these plots, which began in 1906; these images are stored at the Desert Laboratory Collection of Repeat Photography in Tucson. Initial data collection consisted of grid-mapping the plots manually on graph paper; starting in 1993, Total Stations (which allow a direct digitalization, and more accurate mapping) were used to survey root crowns and canopies.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Archives","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"ESA","doi":"10.1890/12-1164.1","usgsCitation":"Rodriguez-Buritica, S., Raichle, H., Webb, R., Turner, R., and Venable, L., 2013, One hundred and six years of population and community dynamics of Sonoran Desert Laboratory perennials: Ecological Archives, v. 94, no. 4, p. 976-976, https://doi.org/10.1890/12-1164.1.","productDescription":"1 p.","startPage":"976","endPage":"976","ipdsId":"IP-038596","costCenters":[{"id":148,"text":"Branch of Regional Research-Western Region","active":false,"usgs":true}],"links":[{"id":273435,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":273434,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/12-1164.1"}],"volume":"94","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51b2f2dbe4b01368e589e3c2","contributors":{"authors":[{"text":"Rodriguez-Buritica, Susana","contributorId":29723,"corporation":false,"usgs":true,"family":"Rodriguez-Buritica","given":"Susana","affiliations":[],"preferred":false,"id":464788,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Raichle, Helen hraichle@usgs.gov","contributorId":4387,"corporation":false,"usgs":true,"family":"Raichle","given":"Helen","email":"hraichle@usgs.gov","affiliations":[],"preferred":true,"id":464786,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Webb, Robert H. rhwebb@usgs.gov","contributorId":1573,"corporation":false,"usgs":false,"family":"Webb","given":"Robert H.","email":"rhwebb@usgs.gov","affiliations":[{"id":12625,"text":"School of Natural Resources and the Environment, University of Arizona, Tucson, AZ, 85721, USA","active":true,"usgs":false}],"preferred":false,"id":464785,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Turner, Raymond M.","contributorId":7383,"corporation":false,"usgs":true,"family":"Turner","given":"Raymond M.","affiliations":[],"preferred":false,"id":464787,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Venable, Larry","contributorId":71861,"corporation":false,"usgs":true,"family":"Venable","given":"Larry","affiliations":[],"preferred":false,"id":464789,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

These models extend spatially the static stability models adopted in geotechnical engineering and adopt an infinite-slope geometry to balance the resisting and the driving forces acting on the sliding mass. An infiltration model is used to determine how rainfall changes pore-water conditions, modulating the local stability/instability conditions. A problem with the existing models is the difficulty in obtaining accurate values for the several variables that describe the material properties of the slopes. The problem is particularly severe when the models are applied over large areas, for which sufficient information on the geotechnical and hydrological conditions of the slopes is not generally available. To help solve the problem, we propose a probabilistic Monte Carlo approach to the distributed modeling of shallow rainfall-induced landslides. For the purpose, we have modified the Transient Rainfall Infiltration and Grid-Based Regional Slope-Stability Analysis (TRIGRS) code. The new code (TRIGRS-P) adopts a stochastic approach to compute, on a cell-by-cell basis, transient pore-pressure changes and related changes in the factor of safety due to rainfall infiltration. Infiltration is modeled using analytical solutions of partial differential equations describing one-dimensional vertical flow in isotropic, homogeneous materials. Both saturated and unsaturated soil conditions can be considered. TRIGRS-P copes with the natural variability inherent to the mechanical and hydrological properties of the slope materials by allowing values of the TRIGRS model input parameters to be sampled randomly from a given probability distribution. The range of variation and the mean value of the parameters can be determined by the usual methods used for preparing the TRIGRS input parameters. The outputs of several model runs obtained varying the input parameters are analyzed statistically, and compared to the original (deterministic) model output. The comparison suggests an improvement of the predictive power of the model of about 10% and 16% in two small test areas, i.e. the Frontignano (Italy) and the Mukilteo (USA) areas, respectively. We discuss the computational requirements of TRIGRS-P to determine the potential use of the numerical model to forecast the spatial and temporal occurrence of rainfall-induced shallow landslides in very large areas, extending for several hundreds or thousands of square kilometers. Parallel execution of the code using a simple process distribution and the Message Passing Interface (MPI) on multi-processor machines was successful, opening the possibly of testing the use of TRIGRS-P for the operational forecasting of rainfall-induced shallow landslides over large regions.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geoscientific Model Development and Discussions","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"European Geosciences Union","doi":"10.5194/gmdd-6-1367-2013","usgsCitation":"Raia, S., Alvioli, M., Rossi, M., Baum, R., Godt, J., and Guzzetti, F., 2013, Improving predictive power of physically based rainfall-induced shallow landslide models: a probablistic approach: Geoscientific Model Development and Discussions, v. 6, p. 1367-1426, https://doi.org/10.5194/gmdd-6-1367-2013.","productDescription":"10 p.","startPage":"1367","endPage":"1426","ipdsId":"IP-042922","costCenters":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"links":[{"id":473771,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.5194/gmdd-6-1367-2013","text":"Publisher Index Page"},{"id":273410,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":273409,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.5194/gmdd-6-1367-2013"}],"volume":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51b1a170e4b022a6a540f998","contributors":{"authors":[{"text":"Raia, S.","contributorId":35218,"corporation":false,"usgs":true,"family":"Raia","given":"S.","email":"","affiliations":[],"preferred":false,"id":476837,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Alvioli, M.","contributorId":36829,"corporation":false,"usgs":true,"family":"Alvioli","given":"M.","affiliations":[],"preferred":false,"id":476838,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Rossi, M.","contributorId":16301,"corporation":false,"usgs":true,"family":"Rossi","given":"M.","email":"","affiliations":[],"preferred":false,"id":476836,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Baum, R.L.","contributorId":68752,"corporation":false,"usgs":true,"family":"Baum","given":"R.L.","email":"","affiliations":[],"preferred":false,"id":476840,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Godt, J.

Resilience proponents have been especially critical of optimization in decision science, at least for those cases where it is focused on the aggressive pursuit of efficiency. In general, optimization of resource systems is held to reduce spatial, temporal, or organizational heterogeneity that would otherwise limit efficiency, leading to homogenization of a system and making it less able to cope with unexpected changes or disturbances. For their part, decision analysts have been critical of resilience proponents for not providing much practical advice to decision makers. We believe a key source of tension between resilience thinking and application of decision science is the pursuit of efficiency in the latter (i.e., choosing the “best” management action or strategy option to maximize productivity of one or few resource components), vs. a desire in the former to keep options open (i.e., maintaining and enhancing diversity). It seems obvious, however, that with managed natural systems, there must be a principle by which to guide decision making, which at a minimumallows for a comparison of projected outcomes associated with decision alternatives. This is true even if the primary concern of decision making is the preservation of system resilience. We describe how a careful framing of conservation problems, especially in terms of management objectives and predictive models, can help reduce the purported tension between resiliencethinking and decision analysis. In particular, objective setting in conservation problems needs to be more attuned to the dynamics of ecological systems and to the possibility of deep uncertainties that underlie the risk of unintended, if not irreversible, outcomes. Resilience thinking also leads to the suggestion that model development should focus more on process rather than pattern, on multiple scales of influence, and on phenomena that can create alternative stability regimes. Although we acknowledge the inherent difficulties in modeling ecological processes, we stress that formulation of useful models need not depend on a thorough mechanistic understanding or precise parameterization, assuming that uncertainty is acknowledged and treated in a systematic manner.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecology and Society","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Resilience Alliance","doi":"10.5751/ES-05544-180227","usgsCitation":"Johnson, F.A., Williams, B.K., and Nichols, J., 2013, Resilience thinking and a decision-analytic approach to conservation: strange bedfellows or essential partners?: Ecology and Society, v. 18, no. 2, 17 p., https://doi.org/10.5751/ES-05544-180227.","productDescription":"17 p.","numberOfPages":"17","ipdsId":"IP-040396","costCenters":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"links":[{"id":473772,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.5751/es-05544-180227","text":"Publisher Index Page"},{"id":275992,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":275991,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.5751/ES-05544-180227"}],"volume":"18","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5200c968e4b009d47a4c23d3","contributors":{"authors":[{"text":"Johnson, Fred A. 0000-0002-5854-3695 fjohnson@usgs.gov","orcid":"https://orcid.org/0000-0002-5854-3695","contributorId":2773,"corporation":false,"usgs":true,"family":"Johnson","given":"Fred","email":"fjohnson@usgs.gov","middleInitial":"A.","affiliations":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true},{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true},{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true}],"preferred":true,"id":481936,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Williams, Byron K. 0000-0001-7644-1396","orcid":"https://orcid.org/0000-0001-7644-1396","contributorId":86616,"corporation":false,"usgs":true,"family":"Williams","given":"Byron","email":"","middleInitial":"K.","affiliations":[{"id":554,"text":"Science and Decisions Center","active":true,"usgs":true}],"preferred":false,"id":481937,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Nichols, James D. 0000-0002-7631-2890 jnichols@usgs.gov","orcid":"https://orcid.org/0000-0002-7631-2890","contributorId":405,"corporation":false,"usgs":true,"family":"Nichols","given":"James D.","email":"jnichols@usgs.gov","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":481935,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Mosquitoes were collected weekly throughout the year using Centers for Disease Control and Prevention (CDC) light traps placed at 1.5 and 6 m above the ground and gravid traps. A total of 379,466 mosquitoes was collected. WNV was identified in 32 pools of mosquitoes comprising four species; 23 positive pools were from Culex nigripalpus collected during 2003. Significantly more positive pools were obtained from Cx. nigripalpus collected in traps placed at 6 m than 1.5 m that year, but abundance did not differ by trap height. In contrast, Cx. nigripalpus abundance was significantly greater in traps placed at 6 m in 2002 and 2004. Annual temporal variation in Cx. nigripalpus peak seasonal abundance has important implications for WNV transmission in Louisiana. One WNV-positive pool, from Cx. erraticus, was collected during the winter of 2004, showing year-round transmission. The potential roles of additional mosquito species in WNV transmission in southeastern Louisiana are discussed.\n\nDisclaimer: The opinions expressed in this article are the opinions of the authors and do not necessarily represent the views of the Centers for Disease Control and Prevention.

These changes to the forest have received considerable attention as they elevate concerns regarding the outcome of wildland fire.   However, attempts to reduce biomass through fuel reduction (i.e., thinning of trees) are often opposed by public interest groups whose objectives include maintaining habitat for species of concern such as the spotted owl, Strix occidentalis, the northern goshawk, Accipiter gentilis, and the Pacific fisher, Martes pennanti. Whether protection of these upper-trophic level species confers adequate conservation of avian forest diversity is unknown. Methodology and Principal Findings:  We use a multi-species occurrence model to estimate the habitat associations of 47 avian species detected at 742 sampling locations within an 880-km<sup>2</sup> area in the Sierra Nevada.  Our approach, which accounts for variations in detectability of species, estimates occurrence probabilities of all species in a community by linking species occurrence models into one hierarchical community model, thus improving inferences on all species, especially those that are rare or observed infrequently.  We address how the avian community is influenced by covariates related to canopy cover, tree size and shrub cover while accounting for the impacts of abiotic variables known to affect species distributions. Conclusions and Significance:  Environmental parameters estimated through our approach emphasize the importance of within and between stand-level heterogeneity in meeting biodiversity objectives and suggests that many avian species would increase under more open canopy habitat conditions than those favored by umbrella species of high conservation concern.  Our results suggest that a more integrated approach that emphasizes maintaining a diversity of habitats across environmental gradients and minimizing urbanization may have a greater benefit to ecosystem functioning then a single-species management focus.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"PLoS ONE","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Public Library of Science","doi":"10.1371/journal.pone.0063088","usgsCitation":"White, A.M., Zipkin, E., Manley, P.N., and Schlesinger, M.D., 2013, Conservation of avian diversity in the Sierra Nevada: moving beyond a single-species management focus: PLoS ONE, v. 8, no. 5, e63088, https://doi.org/10.1371/journal.pone.0063088.","productDescription":"e63088","ipdsId":"IP-043205","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":473775,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1371/journal.pone.0063088","text":"Publisher Index Page"},{"id":273243,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":273240,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1371/journal.pone.0063088"}],"country":"United States","state":"California;Nevada","otherGeospatial":"Sierra Nevada","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -121.0,38.0 ], [ -121.0,39.75 ], [ -119.25,39.75 ], [ -119.25,38.0 ], [ -121.0,38.0 ] ] ] } } ] }","volume":"8","issue":"5","noUsgsAuthors":false,"publicationDate":"2013-05-07","publicationStatus":"PW","scienceBaseUri":"51aefe4ee4b08a3322c2c244","contributors":{"authors":[{"text":"White, Angela M.","contributorId":84255,"corporation":false,"usgs":true,"family":"White","given":"Angela","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":479310,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Zipkin, Elise F.","contributorId":70528,"corporation":false,"usgs":true,"family":"Zipkin","given":"Elise F.","affiliations":[],"preferred":false,"id":479308,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Manley, Patricia N.","contributorId":79010,"corporation":false,"usgs":true,"family":"Manley","given":"Patricia","email":"","middleInitial":"N.","affiliations":[],"preferred":false,"id":479309,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Schlesinger, Matthew D.","contributorId":103954,"corporation":false,"usgs":true,"family":"Schlesinger","given":"Matthew","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":479311,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

This process may contribute to the formation of nutrient-rich tree islands within the expansive oligotrophic marshes of the Everglades (Florida, United States). This study presents hydrogeochemical data indicating that tree root water uptake is a primary driver of groundwater ion accumulation across one of these islands. Sap flow, soil moisture, water level, water chemistry, and rainfall were measured to identify the relationships between climate, transpiration, and groundwater uptake by phreatophytes and to examine the effect this uptake has on groundwater chemistry and mineral formation in three woody plant communities of differing elevations. During the dry season, trees relied more on groundwater for transpiration, which led to a depressed water table and the advective movement of groundwater and dissolved ions, including phosphorus, from the surrounding marsh towards the centre of the island. Ion exclusion during root water uptake led to elevated concentrations of all major dissolved ions in the tree island groundwater compared with the adjacent marsh. Groundwater was predominately supersaturated with respect to aragonite and calcite in the lower-elevation woody communities, indicating the potential for soil formation. Elevated groundwater phosphorous concentrations detected in the highest-elevation woody community were associated with the leaching of inorganic sediments (i.e. hydroxyapatite) in the vadose zone. Understanding the complex feedback mechanisms regulating plant/groundwater/surface water interactions, nutrient dynamics, and potential soil formation is necessary to manage and restore patterned wetlands such as the Everglades.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecohydrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1002/eco.1394","usgsCitation":"Sullivan, P.L., Engel, V.C., Ross, M.S., and Price, R.M., 2013, The influence of vegetation on the hydrodynamics and geomorphology of a tree island in Everglades National Park (Florida, United States): Ecohydrology, v. 7, no. 2, p. 727-744, https://doi.org/10.1002/eco.1394.","productDescription":"18 p.","startPage":"727","endPage":"744","ipdsId":"IP-039164","costCenters":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"links":[{"id":279853,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":279852,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/eco.1394"}],"country":"United States","state":"Florida","otherGeospatial":"Everglades National Park","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -81.5205,24.851 ], [ -81.5205,25.8915 ], [ -80.3887,25.8915 ], [ -80.3887,24.851 ], [ -81.5205,24.851 ] ] ] } } ] }","volume":"7","issue":"2","noUsgsAuthors":false,"publicationDate":"2013-06-10","publicationStatus":"PW","scienceBaseUri":"5295d12be4b0becc369c8c9f","contributors":{"authors":[{"text":"Sullivan, Pamela L.","contributorId":107605,"corporation":false,"usgs":true,"family":"Sullivan","given":"Pamela","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":486864,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Engel, Victor C. 0000-0002-3858-7308 vengel@usgs.gov","orcid":"https://orcid.org/0000-0002-3858-7308","contributorId":2329,"corporation":false,"usgs":true,"family":"Engel","given":"Victor","email":"vengel@usgs.gov","middleInitial":"C.","affiliations":[{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true},{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"preferred":true,"id":486861,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ross, Michael S.","contributorId":45406,"corporation":false,"usgs":true,"family":"Ross","given":"Michael","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":486862,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Price, Rene M.","contributorId":52880,"corporation":false,"usgs":true,"family":"Price","given":"Rene","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":486863,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Several physiological and environmental factors alter these locomotor rhythms. As sea lamprey, Petromyzon marinus, progress through their life cycle, their locomotor activity rhythm changes multiple times. The goal of this study was to elucidate the activity patterns of adult female sea lamprey during the sexual maturation process and discern the interactions of these patterns with exposure to male pheromones. During these stages, preovulated and ovulated adult females are exposed to sex pheromone compounds, which are released by spermiated males and attract ovulated females to the nest for spawning. The locomotor behavior of adult females was monitored in a natural stream with a passive integrated tag responder system as they matured, and they were exposed to a sex pheromone treatment (spermiated male washings) or a control (prespermiated male washings). Results showed that, dependent on the hour of day, male sex pheromone compounds reduce total activity (p < 0.05) and cause increases in activity during several daytime hours in preovulated and ovulated females. These results are one of the first examples of how sex pheromones modulate a locomotor rhythm in a vertebrate, and they suggest that the interaction between maturity stage and sex pheromone exposure contributes to the differential locomotor rhythms found in adult female sea lamprey. This phenomenon may contribute to the reproductive synchrony of mature adults, thus increasing reproductive success in this species.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Biological Rhythms","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Society for Research on Biological Rhythms","doi":"10.1177/0748730413488994","usgsCitation":"Walaszczyk, E., Johnson, N.S., Steibel, J.P., and Li, W., 2013, Effects of sex pheromones and sexual maturation on locomotor activity in female sea lamprey (Petromyzon marinus): Journal of Biological Rhythms, v. 28, no. 3, p. 218-226, https://doi.org/10.1177/0748730413488994.","productDescription":"9 p.","startPage":"218","endPage":"226","numberOfPages":"9","ipdsId":"IP-045299","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":473786,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1177/0748730413488994","text":"Publisher Index Page"},{"id":277123,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":277122,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1177/0748730413488994"}],"volume":"28","issue":"3","noUsgsAuthors":false,"publicationDate":"2013-06-04","publicationStatus":"PW","scienceBaseUri":"521f1be6e4b0f8bf2b07610b","contributors":{"authors":[{"text":"Walaszczyk, Erin J.","contributorId":50811,"corporation":false,"usgs":true,"family":"Walaszczyk","given":"Erin J.","affiliations":[],"preferred":false,"id":483197,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Johnson, Nicholas S. 0000-0002-7419-6013 njohnson@usgs.gov","orcid":"https://orcid.org/0000-0002-7419-6013","contributorId":597,"corporation":false,"usgs":true,"family":"Johnson","given":"Nicholas","email":"njohnson@usgs.gov","middleInitial":"S.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":483196,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Steibel, Juan Pedro","contributorId":104385,"corporation":false,"usgs":true,"family":"Steibel","given":"Juan","email":"","middleInitial":"Pedro","affiliations":[],"preferred":false,"id":483199,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Li, Weiming","contributorId":65440,"corporation":false,"usgs":true,"family":"Li","given":"Weiming","affiliations":[],"preferred":false,"id":483198,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The explosive activity triggered PDCs to the north and northeast, which felled modest patches of forest as far as 2 km from the caldera rim.  Felled trees pointing in the down-current direction dominate the disturbance zones.  The PDC on the north flank of Chaitén left a decimeters-thick, bipartite deposit having a basal layer of poorly sorted, fines-depleted pumice-and-lithic coarse ash and lapilli, which transitions abruptly to fines-enriched pumice-and-lithic coarse ash.  The deposit contains fragments of mostly uncharred organics near its base; vegetation protruding above the deposit is uncharred.  The nature of the forest disturbance and deposit characteristics suggest the PDC was dilute, of relatively low temperature (<200°C), and to first approximation had a dynamic pressure of about 2-4 kPa and velocity of about 30-40 ms<sup>-1</sup>.  It was formed by directionally focused explosions throughout the volcano's prehistoric, intracaldera lava dome.  Dilute, low-temperature PDCs that exited the caldera over a low point on the east-southeast caldera rim deposited meters-thick fill of stratified beds of pumice-and-lithic coarse ash and lapilli.  They did not fell large trees more than a few hundred of meters from the caldera rim and were thus less energetic than those on the north and northeast flanks.  They likely formed by partial collapses of the margins of vertical eruption columns.  In the Chaitén River valley south of the volcano, several-meter-thick deposits of two block-and-ash flow (BAF) PDCs are preserved.  Both have a coarse ash matrix that supports blocks and lapilli predominantly of lithic rhyolite dome rock, minor obsidian, and local bedrock.  One deposit was emplaced by a BAF that traveled an undetermined distance downvalley between June and November 2008, apparently triggered by partial collapse of a newly effused lava dome on that started growing on 12 May.  A second, and larger, BAF related to another collapse of the new lava dome on 19 February 2009 traveled to within 3 km of the village of Chaitén, 10 km downstream of the volcano.  It deposited as much as 8-10 m of diamict having sedimentary characteristics very similar to the previous BAF deposit.  Charred trees locally encased within the BAD deposits suggest that the flows were of moderate temperature, perhaps as much as 300°C.  Erosion of the BAD deposits filling the Chaitén River channel has delivered substantial sediment loads downstream, contributing to channel instability and challenged river management.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Andean Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Servicio Nacional de Geología y Minería","publisherLocation":"Santiago, Chile","doi":"10.5027/andgeoV40n2-a09","usgsCitation":"Major, J.J., Pierson, T.C., Hoblitt, R.P., and Moreno, H., 2013, Pyroclastic density currents associated with the 2008-2009 eruption of Chaitén Volcano (Chile): forest disturbances, deposits, and dynamics: Andean Geology, v. 40, no. 2, p. 324-358, https://doi.org/10.5027/andgeoV40n2-a09.","productDescription":"35 p.","startPage":"324","endPage":"358","numberOfPages":"35","costCenters":[],"links":[{"id":473787,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.5027/andgeov40n2-a09","text":"Publisher Index Page"},{"id":291185,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":291182,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.5027/andgeoV40n2-a09"}],"country":"Chile","city":"Chait�n","otherGeospatial":"Chait�n Volcano","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -72.902119,-42.963783 ], [ -72.902119,-42.70194 ], [ -72.389881,-42.70194 ], [ -72.389881,-42.963783 ], [ -72.902119,-42.963783 ] ] ] } } ] }","volume":"40","issue":"2","noUsgsAuthors":false,"publicationDate":"2013-05-30","publicationStatus":"PW","scienceBaseUri":"57f7f2dde4b0bc0bec0a063c","contributors":{"authors":[{"text":"Major, Jon J. 0000-0003-2449-4466 jjmajor@usgs.gov","orcid":"https://orcid.org/0000-0003-2449-4466","contributorId":439,"corporation":false,"usgs":true,"family":"Major","given":"Jon","email":"jjmajor@usgs.gov","middleInitial":"J.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":496763,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pierson, Thomas C. 0000-0001-9002-4273 tpierson@usgs.gov","orcid":"https://orcid.org/0000-0001-9002-4273","contributorId":2498,"corporation":false,"usgs":true,"family":"Pierson","given":"Thomas","email":"tpierson@usgs.gov","middleInitial":"C.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":496765,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hoblitt, Richard P. rhoblitt@usgs.gov","contributorId":1937,"corporation":false,"usgs":true,"family":"Hoblitt","given":"Richard","email":"rhoblitt@usgs.gov","middleInitial":"P.","affiliations":[{"id":157,"text":"Cascades Volcano Observatory","active":false,"usgs":true}],"preferred":false,"id":496764,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Moreno, Hugo","contributorId":20232,"corporation":false,"usgs":true,"family":"Moreno","given":"Hugo","email":"","affiliations":[],"preferred":false,"id":496766,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

This study is the first of its kind to assemble, reprocess, describe, and disseminate a georeferenced U.S. database providing a long-term, detailed characterization of flash flooding in terms of spatiotemporal behavior and specificity of impacts. The database is composed of three primary sources: 1) the entire archive of automated discharge observations from the U.S. Geological Survey that has been reprocessed to describe individual flooding events, 2) flash-flooding reports collected by the National Weather Service from 2006 to the present, and 3) witness reports obtained directly from the public in the Severe Hazards Analysis and Verification Experiment during the summers 2008–10. Each observational data source has limitations; a major asset of the unified flash flood database is its collation of relevant information from a variety of sources that is now readily available to the community in common formats. It is anticipated that this database will be used for many diverse purposes, such as evaluating tools to predict flash flooding, characterizing seasonal and regional trends, and improving understanding of dominant flood-producing processes. We envision the initiation of this community database effort will attract and encompass future datasets.","language":"English","publisher":"American Meteorological Society","doi":"10.1175/BAMS-D-12-00198.1","usgsCitation":"Gourley, J., Hong, Y., Flamig, Z.L., Arthur, A., Clark, R., Calianno, M., Ruin, I., Ortel, T., Wieczorek, M., Kirstetter, P., Clark, E., and Krajewski, W.F., 2013, A Unified Flash Flood Database across the United States: Bulletin of the American Meteorological Society, v. 94, no. 6, p. 799-805, https://doi.org/10.1175/BAMS-D-12-00198.1.","productDescription":"7 p.","startPage":"799","endPage":"805","ipdsId":"IP-038441","costCenters":[{"id":344,"text":"Illinois Water Science Center","active":true,"usgs":true},{"id":41514,"text":"Maryland-Delaware-District of Columbia  Water Science Center","active":true,"usgs":true}],"links":[{"id":473789,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1175/bams-d-12-00198.1","text":"Publisher Index Page"},{"id":278144,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -124.8,24.5 ], [ -124.8,49.383 ], [ -66.95,49.383 ], [ -66.95,24.5 ], [ -124.8,24.5 ] ] ] } } ] }","volume":"94","issue":"6","noUsgsAuthors":false,"publicationDate":"2013-06-01","publicationStatus":"PW","scienceBaseUri":"52455761e4b0b3d37307e168","contributors":{"authors":[{"text":"Gourley, Jonathan J.","contributorId":100733,"corporation":false,"usgs":true,"family":"Gourley","given":"Jonathan J.","affiliations":[],"preferred":false,"id":484607,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hong, Yang","contributorId":67000,"corporation":false,"usgs":true,"family":"Hong","given":"Yang","affiliations":[],"preferred":false,"id":484604,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Flamig, Zachary L.","contributorId":62515,"corporation":false,"usgs":true,"family":"Flamig","given":"Zachary","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":484603,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Arthur, Ami","contributorId":79012,"corporation":false,"usgs":true,"family":"Arthur","given":"Ami","email":"","affiliations":[],"preferred":false,"id":484605,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Clark, Robert","contributorId":40471,"corporation":false,"usgs":true,"family":"Clark","given":"Robert","affiliations":[],"preferred":false,"id":484601,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Calianno, Martin","contributorId":60115,"corporation":false,"usgs":true,"family":"Calianno","given":"Martin","email":"","affiliations":[],"preferred":false,"id":484602,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Ruin, Isabelle","contributorId":34419,"corporation":false,"usgs":true,"family":"Ruin","given":"Isabelle","email":"","affiliations":[],"preferred":false,"id":484600,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Ortel, Terry W. tortel@usgs.gov","contributorId":2822,"corporation":false,"usgs":true,"family":"Ortel","given":"Terry W.","email":"tortel@usgs.gov","affiliations":[{"id":344,"text":"Illinois Water Science Center","active":true,"usgs":true}],"preferred":false,"id":484598,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Wieczorek, Michael mewieczo@usgs.gov","contributorId":2309,"corporation":false,"usgs":true,"family":"Wieczorek","given":"Michael","email":"mewieczo@usgs.gov","affiliations":[{"id":374,"text":"Maryland Water Science Center","active":true,"usgs":true}],"preferred":false,"id":484597,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Kirstetter, Pierre-Emmanuel","contributorId":91399,"corporation":false,"usgs":true,"family":"Kirstetter","given":"Pierre-Emmanuel","affiliations":[],"preferred":false,"id":484606,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Clark, Edward","contributorId":106747,"corporation":false,"usgs":true,"family":"Clark","given":"Edward","affiliations":[],"preferred":false,"id":484608,"contributorType":{"id":1,"text":"Authors"},"rank":11},{"text":"Krajewski, Witold F.","contributorId":27348,"corporation":false,"usgs":true,"family":"Krajewski","given":"Witold","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":484599,"contributorType":{"id":1,"text":"Authors"},"rank":12}]}}

Hydropeaking flow regimes for electrical power production inundate areas that create temporary suitable habitat for fish that may be rapidly drained. Robust redhorse <i>Moxostoma robustum</i>, an imperiled, rare fish species, uses such temporary habitats to spawn, but when power generation ceases, these areas are dewatered until the next pulse of water is released. We experimentally simulated the effects of dewatering periods on the survival of robust redhorse eggs and larvae in the laboratory. Robust redhorse eggs were placed in gravel in eyeing-hatching jars (three jars per treatment) and subjected to one of four dewatering periods (6, 12, 24 and 48 h), followed by 12 h of inundation for each treatment, and a control treatment was never dewatered. Egg desiccation was observed in some eggs in the 24- and 48-h treatments after one dewatering period. For all treatments except the control, the subsequent dewatering period after eggs hatched was lethal. Larval emergence for the control treatment was observed on day 5 post-hatching and continued until the end of the experiment (day 21). Larval survival was significantly different between the control and all dewatering treatments for individuals in the gravel. These findings support the need for hydropower facilities to set minimum flows to maintain inundation of spawning areas for robust redhorse and other species to reduce dewatering mortality.</p>","language":"English","publisher":"John Wiley & Sons","publisherLocation":"Chichester, West Sussex, UK","doi":"10.1002/rra.2561","collaboration":"State Wildlife Grant through the North Carolina Wildlife Resources Commission; Progress Energy, North Carolina State University; North Carolina Wildlife Resources Commission; US Fish and Wildlife Service; Wildlife Management Institute","usgsCitation":"Fisk, J.M., Kwak, T.J., Heise, R.J., and Sessions, F.W., 2013, Redd dewatering effects on hatching and larval survival of the robust redhorse: River Research and Applications, v. 29, no. 5, p. 574-581, https://doi.org/10.1002/rra.2561.","productDescription":"8 p.","startPage":"574","endPage":"581","numberOfPages":"8","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-031549","costCenters":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"links":[{"id":301370,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"29","issue":"5","publishingServiceCenter":{"id":8,"text":"Raleigh PSC"},"noUsgsAuthors":false,"publicationDate":"2012-01-31","publicationStatus":"PW","scienceBaseUri":"55853d56e4b023124e8f5b37","contributors":{"authors":[{"text":"Fisk, J.

Unfortunately, these same coastal waters are also a popular “habitat” for humans. In the past, the overlap between human and manatee habitat allowed for manatee hunting and threatened the survival of these gentle marine mammals. Today, however, threats are much more inadvertent and are often related to coastal development, degraded habitats and boat strikes. \n\nIn the state of Florida, decades of research on the species’ biological needs have helped conservationists address threats to its survival. For example, low wake zones and boater education have protected manatees from boat strikes, and many of their critical winter refuges are now protected. The Florida population has grown steadily, thus increasing from approximately 1,200 in 1991 to more than 5,000 in 2010. It is conceivable that in Florida manatees may one day be reclassified as “threatened” rather than “endangered.” \n\nYet, in other parts of the Caribbean, threats still loom. This includes small, isolated manatee populations found on islands that can be more susceptible to extinction and lack of genetic diversity. To ensure the species’ long-term viability, scientists have turned their sights to the overall population dynamics of manatees throughout the Caribbean. Molecular genetics has provided new insights into long-term threats the species faces. Fortunately, the emerging field of conservation genetics provides managers with tools and strategies for protecting the species’ long-term viability.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"livebetter Magazine","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Center for a Better Life","usgsCitation":"Hunter, M., 2013, The silent threat of low genetic diversity: livebetter Magazine, no. 32.","ipdsId":"IP-045114","costCenters":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"links":[{"id":277177,"type":{"id":15,"text":"Index Page"},"url":"https://www.centerforabetterlife.com/eng/magazine/article_detail.lasso?id=449"},{"id":277178,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"issue":"32","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5221bee8e4b001cbb8a34f3b","contributors":{"authors":[{"text":"Hunter, Margaret E. 0000-0002-4760-9302 mhunter@usgs.gov","orcid":"https://orcid.org/0000-0002-4760-9302","contributorId":4888,"corporation":false,"usgs":true,"family":"Hunter","given":"Margaret E.","email":"mhunter@usgs.gov","affiliations":[{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"preferred":false,"id":483280,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

In the months that followed, the excess heat triggered melting and ablation of Redoubt's glaciers, beginning at the summit and propagating to lower elevations as the unrest accelerated. A variety of morphological changes were observed, including the creation of ice cauldrons, areas of wide-spread subsidence, punctures in the ice carved out by steam, and deposition from debris flows. In this paper, we use visual observations, satellite data, and a high resolution digital elevation model of the volcanic edifice to calculate ice loss at Redoubt as a function of time. Our aim is to establish from this time series a proxy for heat flow that can be compared to other data sets collected along the same time interval.

The upper part of the Drift glacier covers the area of recent volcanism, making this part of ice mass most susceptible to the effect of volcanic heating.

Despite their limited coverage on the landscape, streams play a significant role in the processing, gaseous emission, and downstream export of C, and small streams are thought to be particularly important because of their close connection with the surrounding landscape. However, ecosystem carbon studies do not commonly incorporate the role of the aquatic conduit. We measured carbon dioxide (CO</span><sub>2</sub><span>) and methane (CH</span><sub>4</sub><span>) concentrations and emissions in a headwater stream network of interior Alaska underlain by permafrost to assess the potential role of stream gas emissions in the regional carbon balance. First-order streams exhibited the greatest variability in fluxes of CO</span><sub>2</sub><span> and CH</span><sub>4,</sub><span>and the greatest mean </span><i>p</i><span>CO</span><sub>2</sub><span>. High-resolution time series of stream </span><i>p</i><span>CO</span><sub>2</sub><span> and discharge at two locations on one first-order stream showed opposing </span><i>p</i><span>CO</span><sub>2</sub><span> responses to storm events, indicating the importance of hydrologic flowpaths connecting CO</span><sub>2</sub><span>-rich soils with surface waters. Repeated longitudinal surveys on the stream showed consistent areas of elevated </span><i>p</i><span>CO</span><sub>2</sub><span> and </span><i>p</i><span>CH</span><sub>4</sub><span>, indicative of discrete hydrologic flowpaths delivering soil water and groundwater having varying chemistry. Up-scaled basin estimates of stream gas emissions suggest that streams may contribute significantly to catchment-wide CH</span><sub>4</sub><span> emissions. Overall, our results indicate that while stream-specific gas emission rates are disproportionately high relative to the terrestrial landscape, both stream surface area and catchment normalized emission rates were lower than those documented for the Yukon River Basin as a whole. This may be due to limitations of C sources and/or C transport to surface waters.</span></p>","language":"English","publisher":"AGU Publications","doi":"10.1002/jgrg.20034","usgsCitation":"Crawford, J.T., Striegl, R.G., Wickland, K.P., Dornblaser, M.M., and Stanley, E.H., 2013, Emissions of carbon dioxide and methane from a headwater stream network of interior Alaska: Journal of Geophysical Research G: Biogeosciences, v. 118, no. 2, p. 482-494, https://doi.org/10.1002/jgrg.20034.","productDescription":"13 p.","startPage":"482","endPage":"494","ipdsId":"IP-038788","costCenters":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"links":[{"id":473795,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/jgrg.20034","text":"Publisher Index Page"},{"id":335837,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"118","issue":"2","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationDate":"2013-04-11","publicationStatus":"PW","scienceBaseUri":"58ac0e31e4b0ce4410e7d608","contributors":{"authors":[{"text":"Crawford, John T. 0000-0003-4440-6945 jtcrawford@usgs.gov","orcid":"https://orcid.org/0000-0003-4440-6945","contributorId":4081,"corporation":false,"usgs":true,"family":"Crawford","given":"John","email":"jtcrawford@usgs.gov","middleInitial":"T.","affiliations":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":669865,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Striegl, Robert G. 0000-0002-8251-4659 rstriegl@usgs.gov","orcid":"https://orcid.org/0000-0002-8251-4659","contributorId":1630,"corporation":false,"usgs":true,"family":"Striegl","given":"Robert","email":"rstriegl@usgs.gov","middleInitial":"G.","affiliations":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true},{"id":36183,"text":"Hydro-Ecological Interactions Branch","active":true,"usgs":true},{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":false,"id":669868,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wickland, Kimberly P. 0000-0002-6400-0590 kpwick@usgs.gov","orcid":"https://orcid.org/0000-0002-6400-0590","contributorId":1835,"corporation":false,"usgs":true,"family":"Wickland","given":"Kimberly","email":"kpwick@usgs.gov","middleInitial":"P.","affiliations":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":36183,"text":"Hydro-Ecological Interactions Branch","active":true,"usgs":true},{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"preferred":true,"id":669866,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Dornblaser, Mark M. 0000-0002-6298-3757 mmdornbl@usgs.gov","orcid":"https://orcid.org/0000-0002-6298-3757","contributorId":1636,"corporation":false,"usgs":true,"family":"Dornblaser","given":"Mark","email":"mmdornbl@usgs.gov","middleInitial":"M.","affiliations":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"preferred":true,"id":669867,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Stanley, Emily H.","contributorId":55725,"corporation":false,"usgs":false,"family":"Stanley","given":"Emily","email":"","middleInitial":"H.","affiliations":[{"id":12951,"text":"Center for Limnology, University of Wisconsin Madison","active":true,"usgs":false}],"preferred":false,"id":669869,"contributorType":{"id":1,"text":"Authors"},"rank":11}]}}

Already substantial seepage rates changed by 7% and 16% in response to relatively small rain events at two lakes in the northeastern USA, but did not change in response to two larger rain events at a lake in Minnesota. However, seepage at that same Minnesota lake changed by 10% each day in response to withdrawals from evapotranspiration. Seepage increased by more than an order of magnitude when a seiche occurred in the Great Salt Lake, Utah. Near the head of a fjord in Puget Sound, Washington, seepage in the intertidal zone varied greatly from −115 to +217 cm d−1 in response to advancing and retreating tides when the time-averaged seepage was upward at +43 cm d−1. At all locations, seepage variability increased by one to several orders of magnitude in response to wind and associated waves. Net seepage remained unchanged by wind unless wind also induced a lake seiche. These examples from sites distributed across a broad geographic region indicate that temporal variability in seepage in response to common hydrological events is much larger than previously realized. At most locations, seepage responded within minutes to changes in surface-water stage and within minutes to hours to groundwater recharge associated with rainfall. Likely implications of this dynamism include effects on water residence time, geochemical transformations, and ecological conditions at and near the sediment-water interface.","language":"English","publisher":"American Geophysical Union","doi":"10.1002/wrcr.20198","usgsCitation":"Rosenberry, D.O., Sheibley, R.W., Cox, S.E., Simonds, F.W., and Naftz, D.L., 2013,

It is one of a series of metalliferous middle Cretaceous porphyritic granodiorite, quartz monzonite, and diorite bodies, evolved from lower crust and metasomatized lithospheric mantle melts, which formed along much of the length of the North American craton suture with the Peninsular-Alexander-Wrangellia arc. The porphyry deposits were emplaced within the northernmost two of a series of ca. 130 to 80 Ma flysch basins that define the suture, as well as into arc rocks immediately seaward of the two basins. Deposits include the ca. 100 to 90 Ma Pebble, Neacola, and other porphyry prospects along the Kahiltna basin-Peninsula terrane boundary, and the ca. 115 to 105 Ma Baultoff, Carl Creek, Horsfeld, Orange Hill, Bond Creek, and Chisna porphyries along the Nutzotin basin-Wrangellia terrane boundary.</p><p id=\"p-2\">The porphyry deposits probably formed along the craton margin more than 1,000 km to the south of their present latitude. Palinspastic reconstructions of plate kinematics from this period are particularly difficult because magmatism overlaps the 119 to 83 Ma Cretaceous Normal Superchron, a period when sea-floor magnetic data are lacking. Our favored scenario is that ore formation broadly overlaps the cessation of sedimentation and contraction and the transition to a transpressional continental margin regime, such that the remnant ocean basins were converted to strike-slip basins. The basins and outboard Peninsular-Alexander-Wrangellia composite superterrane, which are all located seaward of the deep crustal Denali-Farewell fault system, were subjected to northerly dextral transpression for as long as perhaps 50 m.y., beginning at ca. 95 ± 10 Ma. The onset of this transpression was marked by development of the mineralized bodies along fault segments on the seaward side of the basins.</p><p id=\"p-3\">Geochemical and radiogenic isotopic data for igneous rocks associated with the Pebble porphyry deposit suggest continuous melt derivation from enriched lithosphere of a recently metasomatized mantle. These geochemical characteristics, coupled with the arc-continent-related collisional setting, suggest that lithospheric thickening and postcollisional lithospheric melting are the most likely cause of the ore-related magmatism. Subsequent to translation of the Alaskan margin terranes and early Tertiary oroclinal bending of Alaska, the northernmost Kahiltna basin and the Pebble deposit, as well as the other porphyry systems, reached their present-day locations along southern Alaska.</p>","language":"English","publisher":"Society of Economic Geologists","doi":"10.2113/econgeo.108.3.405","usgsCitation":"Goldfarb, R.J., Anderson, E., and Hart, C., 2013, Tectonic setting of the pebble and other copper-gold-molybdenum porphyry deposits within the evolving middle cretaceous continental margin of Northwestern North America: Economic Geology, v. 108, no. 3, p. 405-419, https://doi.org/10.2113/econgeo.108.3.405.","productDescription":"15 p.","startPage":"405","endPage":"419","ipdsId":"IP-036827","costCenters":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"links":[{"id":342889,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Canada, United States","state":"Alaska, Yukon","otherGeospatial":"Gulf of Alaska","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -160.048828125,\n              54.265224078605684\n            ],\n            [\n              -160.048828125,\n              50.84757295365389\n            ],\n            [\n              -129.90234375,\n              51.069016659603896\n            ],\n            [\n              -130.25390625,\n              64.47279382008166\n            ],\n            [\n              -160.576171875,\n              64.54844014422517\n            ],\n            [\n              -160.048828125,\n              54.265224078605684\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"108","issue":"3","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationDate":"2013-03-07","publicationStatus":"PW","scienceBaseUri":"59521d29e4b062508e3c36dc","contributors":{"authors":[{"text":"Goldfarb, Richard J. goldfarb@usgs.gov","contributorId":1205,"corporation":false,"usgs":true,"family":"Goldfarb","given":"Richard","email":"goldfarb@usgs.gov","middleInitial":"J.","affiliations":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":false,"id":700450,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Anderson, Eric D. 0000-0002-0138-6166 ericanderson@usgs.gov","orcid":"https://orcid.org/0000-0002-0138-6166","contributorId":172766,"corporation":false,"usgs":true,"family":"Anderson","given":"Eric","email":"ericanderson@usgs.gov","middleInitial":"D.","affiliations":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"preferred":true,"id":700449,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hart, Craig J.","contributorId":193430,"corporation":false,"usgs":false,"family":"Hart","given":"Craig J.","affiliations":[],"preferred":false,"id":700451,"contributorType":{"id":1,"text":"Authors"},"rank":11}]}}

The Giant Gartersnake (Thamnophis gigas) is an example of a secretive, wary, and generally difficult-to-sample species about which little is known regarding its patterns of occurrence and demography. We therefore evaluated modifications to existing traps to increase the detection and capture probabilities of the Giant Gartersnake to improve the precision with which occurrence, abundance, survival, and other demographic parameters are estimated. We found that adding a one-way valve constructed of cable ties to the small funnel opening of traps and adding hardware cloth extensions to the wide end of funnels increased capture rates of the Giant Gartersnake by 5.55 times (95% credible interval = 2.45–10.51) relative to unmodified traps. The effectiveness of these modifications was insensitive to the aquatic habitat type in which they were deployed. The snout-vent length of the smallest and largest captured snakes did not vary among trap modifications. These trap modifications are expected to increase detection and capture probabilities of the Giant Gartersnake, and show promise for increasing the precision with which demographic parameters can be estimated for this species. We anticipate that the trap modifications found effective in this study will be applicable to a variety of aquatic and semi-aquatic reptiles and amphibians and improve conservation efforts for these species.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Herpetological Conservation and Biology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Herpetological Conservation and Biology","usgsCitation":"Halstead, B., Wylie, G.D., and Casazza, M.L., 2013, Efficacy of trap modifications for increasing capture rates of aquatic snakes in floating aquatic funnel traps: Herpetological Conservation and Biology, v. 8, no. 1, p. 65-74.","productDescription":"10 p.","startPage":"65","endPage":"74","ipdsId":"IP-042617","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":272937,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":272936,"type":{"id":11,"text":"Document"},"url":"https://herpconbio.org/Volume_8/Issue_1/Halstead_etal_2013.pdf"}],"volume":"8","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51a71564e4b09db86f875c6b","contributors":{"authors":[{"text":"Halstead, Brian J. 0000-0002-5535-6528 bhalstead@usgs.gov","orcid":"https://orcid.org/0000-0002-5535-6528","contributorId":3051,"corporation":false,"usgs":true,"family":"Halstead","given":"Brian J.","email":"bhalstead@usgs.gov","affiliations":[{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true},{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":479031,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wylie, Glenn D. 0000-0002-7061-6658 glenn_wylie@usgs.gov","orcid":"https://orcid.org/0000-0002-7061-6658","contributorId":3052,"corporation":false,"usgs":true,"family":"Wylie","given":"Glenn","email":"glenn_wylie@usgs.gov","middleInitial":"D.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":479032,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Casazza, Michael L. 0000-0002-5636-735X mike_casazza@usgs.gov","orcid":"https://orcid.org/0000-0002-5636-735X","contributorId":2091,"corporation":false,"usgs":true,"family":"Casazza","given":"Michael","email":"mike_casazza@usgs.gov","middleInitial":"L.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":479030,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The gas is held in fine pores that need to be accessed by horizontal drilling and hydrofracturing techniques. Understanding the nature of the pores may provide clues to making gas extraction more efficient. We have investigated two Mississippian Barnett Shale samples, combining small-angle neutron scattering (SANS) and ultrasmall-angle neutron scattering (USANS) to determine the pore size distribution of the shale over the size range 10 nm to 10 μm. By adding deuterated methane (CD<sub>4</sub>) and, separately, deuterated water (D<sub>2</sub>O) to the shale, we have identified the fraction of pores that are accessible to these compounds over this size range. The total pore size distribution is essentially identical for the two samples. At pore sizes >250 nm, >85% of the pores in both samples are accessible to both CD<sub>4</sub> and D<sub>2</sub>O. However, differences in accessibility to CD<sub>4</sub> are observed in the smaller pore sizes (~25 nm). In one sample, CD<sub>4</sub> penetrated the smallest pores as effectively as it did the larger ones. In the other sample, less than 70% of the smallest pores (<25 nm) were accessible to CD<sub>4</sub>, but they were still largely penetrable by water, suggesting that small-scale heterogeneities in methane accessibility occur in the shale samples even though the total porosity does not differ. An additional study investigating the dependence of scattered intensity with pressure of CD<sub>4</sub> allows for an accurate estimation of the pressure at which the scattered intensity is at a minimum. This study provides information about the composition of the material immediately surrounding the pores. Most of the accessible (open) pores in the 25 nm size range can be associated with either mineral matter or high reflectance organic material. However, a complementary scanning electron microscopy investigation shows that most of the pores in these shale samples are contained in the organic components. The neutron scattering results indicate that the pores are not equally proportioned in the different constituents within the shale. There is some indication from the SANS results that the composition of the pore-containing material varies with pore size; the pore size distribution associated with mineral matter is different from that associated with organic phases.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Energy & Fuels","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"ACS Publications","doi":"10.1021/ef301859s","usgsCitation":"Ruppert, L.F., Sakurovs, R., Blach, T.P., He, L., Melnichenko, Y., Mildner, D.F., and Alcantar-Lopez, L., 2013, A USANS/SANS study of the accessibility of pores in the Barnett Shale to methane and water: Energy & Fuels, v. 27, no. 2, p. 772-779, https://doi.org/10.1021/ef301859s.","productDescription":"8 p.","startPage":"772","endPage":"779","ipdsId":"IP-042255","costCenters":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":272751,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":272750,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/ef301859s"}],"country":"United States","state":"Texas","otherGeospatial":"Barnett Shale","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -106.65,25.84 ], [ -106.65,36.5 ], [ -93.51,36.5 ], [ -93.51,25.84 ], [ -106.65,25.84 ] ] ] } } ] }","volume":"27","issue":"2","noUsgsAuthors":false,"publicationDate":"2013-02-12","publicationStatus":"PW","scienceBaseUri":"519f2c52e4b0687ba0506b46","contributors":{"authors":[{"text":"Ruppert, Leslie F. 0000-0002-7453-1061 lruppert@usgs.gov","orcid":"https://orcid.org/0000-0002-7453-1061","contributorId":660,"corporation":false,"usgs":true,"family":"Ruppert","given":"Leslie","email":"lruppert@usgs.gov","middleInitial":"F.","affiliations":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true},{"id":245,"text":"Eastern Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":478753,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sakurovs, Richard","contributorId":68633,"corporation":false,"usgs":true,"family":"Sakurovs","given":"Richard","affiliations":[],"preferred":false,"id":478756,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Blach, Tomasz P.","contributorId":99866,"corporation":false,"usgs":true,"family":"Blach","given":"Tomasz","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":478758,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"He, Lilin","contributorId":107594,"corporation":false,"usgs":true,"family":"He","given":"Lilin","email":"","affiliations":[],"preferred":false,"id":478759,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Melnichenko, Yuri B.","contributorId":98202,"corporation":false,"usgs":true,"family":"Melnichenko","given":"Yuri B.","affiliations":[],"preferred":false,"id":478757,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Mildner, David F.","contributorId":65747,"corporation":false,"usgs":true,"family":"Mildner","given":"David","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":478755,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Alcantar-Lopez, Leo","contributorId":8361,"corporation":false,"usgs":true,"family":"Alcantar-Lopez","given":"Leo","email":"","affiliations":[],"preferred":false,"id":478754,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

On low-slope, slowly eroding catenas the redistribution of mass occurs predominantly as plasma, the dissolved and suspended constituents in soil water. We applied mass balance methods to track how redistribution via plasma contributed to physical and geochemical differentiation of nine slowly eroding (~ 5 mm ky<sup>− 1</sup>) granitic catenas. The catenas were arrayed in a 3 × 3 climate by relief matrix and located in Kruger National Park, South Africa. Most of the catenas contained at least one illuviated soil profile that had undergone more volumetric expansion and less mass loss, and these soils were located in the lower halves of the slopes. By comparison, the majority of slope positions were eluviated. Soils from the wetter climates (550 and 730 mm precipitation yr<sup>− 1</sup>) generally had undergone greater collapse and lost more mass, while soils in the drier climate (470 mm yr<sup>− 1</sup>) had undergone expansion and lost less mass. Effects of differences in catena relief were less clear. Within each climate zone, soil horizon mass loss and strain were correlated, as were losses of most major elements, illustrating the predominant influence of primary mineral weathering. Nevertheless, mass loss and volumetric collapse did not become extreme because of the skeleton of resistant primary mineral grains inherited from the granite. Colloidal clay redistribution, as traced by the ratio of Ti to Zr in soil, suggested clay losses via suspension from catena eluvial zones. Thus illuviation of colloidal clays into downslope soils may be crucial to catena development by restricting subsurface flow there. Our analysis provides quantitative support for the conceptual understanding of catenas in cratonic landscapes and provides an endmember reference point in understanding the development of slowly eroding soil landscapes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geoderma","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.geoderma.2013.03.023","usgsCitation":"Khomo, L., Bern, C., Hartshorn, A.S., Rogers, K.H., and Chadwick, O.A., 2013, Chemical transfers along slowly eroding catenas developed on granitic cratons in southern Africa: Geoderma, v. 202-203, p. 192-202, https://doi.org/10.1016/j.geoderma.2013.03.023.","productDescription":"11 p.","startPage":"192","endPage":"202","ipdsId":"IP-039308","costCenters":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"links":[{"id":272381,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":272380,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.geoderma.2013.03.023"}],"otherGeospatial":"Africa","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -26.6,-37.5 ], [ -26.6,38.0 ], [ 60.6,38.0 ], [ 60.6,-37.5 ], [ -26.6,-37.5 ] ] ] } } ] }","volume":"202-203","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"519894dce4b0eb382b44ac4f","contributors":{"authors":[{"text":"Khomo, Lesego","contributorId":58921,"corporation":false,"usgs":true,"family":"Khomo","given":"Lesego","affiliations":[],"preferred":false,"id":478654,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bern, Carleton R.","contributorId":59325,"corporation":false,"usgs":true,"family":"Bern","given":"Carleton R.","affiliations":[],"preferred":false,"id":478655,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hartshorn, Anthony S.","contributorId":31285,"corporation":false,"usgs":true,"family":"Hartshorn","given":"Anthony","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":478653,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Rogers, Kevin H.","contributorId":64536,"corporation":false,"usgs":true,"family":"Rogers","given":"Kevin","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":478656,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Chadwick, Oliver A.","contributorId":88244,"corporation":false,"usgs":false,"family":"Chadwick","given":"Oliver","email":"","middleInitial":"A.","affiliations":[{"id":6710,"text":"University of California, Santa Barbara, CA","active":true,"usgs":false}],"preferred":false,"id":478657,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}
