The most recent channel reset occurred in 2008 following a 17-year period of extremely low stream flow and rapid channel narrowing. Flooding was caused by precipitation associated with the remnants of tropical depression Lowell in the Rio Conchos watershed, the largest tributary to the Rio Grande. Floodwaters approached 1500 m3/s (between a 13 and 15 year recurrence interval) and breached levees, inundated communities, and flooded the alluvial valley of the Rio Grande; the wetted width exceeding 2.5 km in some locations. The 2008 flood had the 7th largest magnitude of record, however, conveyed the largest volume of water than any other flood. Because of the narrow pre-flood channel conditions, record flood stages occurred.</p><p>We used pre- and post-flood aerial photographs, channel and floodplain surveys, and 1-dimensional hydraulic models to quantify the magnitude of channel change, investigate the controls of flood-induced geomorphic changes, and measure the post-flood response of the widened channel. These analyses show that geomorphic changes included channel widening, meander migration, avulsions, extensive bar formation, and vertical floodplain accretion. Reach-averaged channel widening between 26 and 52% occurred, but in some localities exceeded 500%. The degree and style of channel response was related, but not limited to, three factors: 1) bed-load supply and transport, 2) pre-flood channel plan form, and 3) rapid declines in specific stream power downstream of constrictions and areas of high channel bed slope. The post-flood channel response has consisted of channel contraction through the aggradation of the channel bed and the formation of fine-grained benches inset within the widened channel margins. The most significant post-flood geomorphic changes have occurred at and downstream from ephemeral tributaries that contribute large volumes of sediment.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geomorphology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.geomorph.2013.06.020","usgsCitation":"Dean, D.J., and Schmidt, J.C., 2013, The geomorphic effectiveness of a large flood on the Rio Grande in the Big Bend region: insights on geomorphic controls and post-flood geomorphic response: Geomorphology, v. 201, p. 183-198, https://doi.org/10.1016/j.geomorph.2013.06.020.","productDescription":"16 p.","startPage":"183","endPage":"198","numberOfPages":"16","ipdsId":"IP-041892","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":288031,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":288030,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.geomorph.2013.06.020"}],"country":"Mexico;United States","state":"Texas","otherGeospatial":"Big Bend National Park;Rio Grande","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -105.0951,28.9719 ], [ -105.0951,30.1996 ], [ -102.1204,30.1996 ], [ -102.1204,28.9719 ], [ -105.0951,28.9719 ] ] ] } } ] }","volume":"201","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"538eee9fe4b0d497d4968550","contributors":{"authors":[{"text":"Dean, David J. 0000-0003-0203-088X djdean@usgs.gov","orcid":"https://orcid.org/0000-0003-0203-088X","contributorId":131047,"corporation":false,"usgs":true,"family":"Dean","given":"David","email":"djdean@usgs.gov","middleInitial":"J.","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":494310,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schmidt, John C. 0000-0002-2988-3869 jcschmidt@usgs.gov","orcid":"https://orcid.org/0000-0002-2988-3869","contributorId":1983,"corporation":false,"usgs":true,"family":"Schmidt","given":"John","email":"jcschmidt@usgs.gov","middleInitial":"C.","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":494309,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Efficient modeling of such trends depends on the consideration of the correlation of population changes with key spatial and environmental covariates. This can provide insights into causal mechanisms and allow spatially explicit summaries at scales that are of interest to management agencies. We expand the hierarchical modeling framework used in the North American Breeding Bird Survey (BBS) by developing a spatially explicit model of temporal trend using a conditional autoregressive (CAR) model. By adopting a formal spatial model for abundance, we produce spatially explicit abundance and trend estimates. Analyses based on large-scale geographic strata such as Bird Conservation Regions (BCR) can suffer from basic imbalances in spatial sampling. Our approach addresses this issue by providing an explicit weighting based on the fundamental sample allocation unit of the BBS. We applied the spatial model to three species from the BBS. Species have been chosen based upon their well-known population change patterns, which allows us to evaluate the quality of our model and the biological meaning of our estimates. We also compare our results with the ones obtained for BCRs using a nonspatial hierarchical model (Sauer and Link 2011). Globally, estimates for mean trends are consistent between the two approaches but spatial estimates provide much more precise trend estimates in regions on the edges of species ranges that were poorly estimated in non-spatial analyses. Incorporating a spatial component in the analysis not only allows us to obtain relevant and biologically meaningful estimates for population trends, but also enables us to provide a flexible framework in order to obtain trend estimates for any area.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"PLoS ONE","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"PLoS","doi":"10.1371/journal.pone.0081867","usgsCitation":"Bled, F., Sauer, J., Pardieck, K.L., Doherty, P., and Royle, J.A., 2013, Modeling trends from North American Breeding Bird Survey data: a spatially explicit approach: PLoS ONE, v. 8, no. 12, 14 p., https://doi.org/10.1371/journal.pone.0081867.","productDescription":"14 p.","ipdsId":"IP-052066","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":473991,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1371/journal.pone.0081867","text":"Publisher Index Page"},{"id":284404,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":284402,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1371/journal.pone.0081867"},{"id":284403,"type":{"id":15,"text":"Index Page"},"url":"https://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0081867;jsessionid=FCB75EDDD2621890E310AC85F997B517"}],"volume":"8","issue":"12","noUsgsAuthors":false,"publicationDate":"2013-12-13","publicationStatus":"PW","scienceBaseUri":"535594b6e4b0120853e8c08b","contributors":{"authors":[{"text":"Bled, Florent","contributorId":93613,"corporation":false,"usgs":true,"family":"Bled","given":"Florent","affiliations":[],"preferred":false,"id":491909,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sauer, John R. jrsauer@usgs.gov","contributorId":3737,"corporation":false,"usgs":true,"family":"Sauer","given":"John R.","email":"jrsauer@usgs.gov","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":491905,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Pardieck, Keith L. 0000-0003-2779-4392 kpardieck@usgs.gov","orcid":"https://orcid.org/0000-0003-2779-4392","contributorId":4104,"corporation":false,"usgs":true,"family":"Pardieck","given":"Keith","email":"kpardieck@usgs.gov","middleInitial":"L.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":491906,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Doherty, Paul","contributorId":64155,"corporation":false,"usgs":true,"family":"Doherty","given":"Paul","affiliations":[],"preferred":false,"id":491908,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Royle, J.

The goal of this study was to investigate environmental drivers of river ecosystem metabolism and macroinvertebrate density in a sub-arctic river. We estimated primary production and respiration rates, sampled benthic macroinvertebrates, and monitored light intensity, discharge rate, and nutrient concentrations in the Chena River, interior Alaska, over two summers. We employed Random Forests models to identify predictor variables for metabolism rates and benthic macroinvertebrate density and biomass, and calculated Spearman correlations between in-stream nutrient levels and metabolism rates. Models indicated that discharge and length of time between high water events were the most important factors measured for predicting metabolism rates. Discharge was the most important variable for predicting benthic macroinvertebrate density and biomass. Primary production rate peaked at intermediate discharge, respiration rate was lowest at the greatest time since last high water event, and benthic macroinvertebrate density was lowest at high discharge rates. The ratio of dissolved inorganic nitrogen to soluble reactive phosphorus ranged from 27:1 to 172:1. We found that discharge plays a key role in regulating stream ecosystem metabolism, but that low phosphorous levels also likely limit primary production in this sub-arctic stream.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Hydrobiologia","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","doi":"10.1007/s10750-012-1272-0","usgsCitation":"Benson, E.R., Wipfli, M.S., Clapcott, J.E., and Hughes, N.F., 2013, Relationships between ecosystem metabolism, benthic macroinvertebrate densities, and environmental variables in a sub-arctic Alaskan river: Hydrobiologia, v. 701, no. 1, p. 189-207, https://doi.org/10.1007/s10750-012-1272-0.","productDescription":"19 p.","startPage":"189","endPage":"207","ipdsId":"IP-028102","costCenters":[{"id":108,"text":"Alaska Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"links":[{"id":473992,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://hdl.handle.net/11122/6957","text":"External Repository"},{"id":275585,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":275584,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10750-012-1272-0"}],"country":"United States","state":"Alaska","otherGeospatial":"Chena River","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -147.93,64.74 ], [ -147.93,64.90 ], [ -147.44,64.90 ], [ -147.44,64.74 ], [ -147.93,64.74 ] ] ] } } ] }","volume":"701","issue":"1","noUsgsAuthors":false,"publicationDate":"2012-09-20","publicationStatus":"PW","scienceBaseUri":"51f8e064e4b0cecbe8fa98a7","contributors":{"authors":[{"text":"Benson, Emily R.","contributorId":41315,"corporation":false,"usgs":true,"family":"Benson","given":"Emily","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":348838,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wipfli, Mark S. 0000-0002-4856-6068 mwipfli@usgs.gov","orcid":"https://orcid.org/0000-0002-4856-6068","contributorId":1425,"corporation":false,"usgs":true,"family":"Wipfli","given":"Mark","email":"mwipfli@usgs.gov","middleInitial":"S.","affiliations":[{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true}],"preferred":true,"id":348836,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Clapcott, Joanne E.","contributorId":71464,"corporation":false,"usgs":true,"family":"Clapcott","given":"Joanne","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":348839,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hughes, Nicholas F.","contributorId":40497,"corporation":false,"usgs":true,"family":"Hughes","given":"Nicholas","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":348837,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The humidity-buffer technique has been applied to study the stability of some of these minerals at 0.1 MPa in terms of temperature-relative humidity space on the basis of hydration-dehydration reversal experiments. Updated phase relations in the binary system MgSO<sub>4</sub>-H<sub>2</sub>O are presented, as an example, to show how reliable thermodynamic data for these minerals could be obtained based on these experimental results and thermodynamic principles. This approach has been applied to sulfate and hydrated sulfate minerals of other metals, including Fe (both ferrous and ferric), Zn, Ni, Co, Cd, and Cu.\n\nMetal-sulfate salts play important roles in the cycling of metals and sulfate in terrestrial systems, and the number of phases extends well beyond the simple sulfate salts that have thus far been investigated experimentally. The oxidation of sulfide minerals, particularly pyrite, is a common process that initiates the formation of efflorescent metal-sulfate minerals. Also, the overall abundance of iron-bearing sulfate salts in nature reflects the fact that the weathering of pyrite or pyrrhotite is the ultimate source for many of these phases. Many aspects of their environmental significance are reviewed, particularly in acute effects to aquatic ecosystems related to the dissolution of sulfate salts during rain storms or snow-melt events.\n\nHydrous Mg, Ca, and Fe sulfates were identified on Mars, with wide distribution and very large quantities at many locations, on the basis of spectroscopic observations from orbital remote sensing and surface explorations by rovers. However, many of these findings do not reveal the detailed information on the degree of hydration that is essential for rigorous interpretation of the hydrologic history of Mars. Laboratory experiments on stability fields, reactions pathways, and reaction rates of hydrous sulfates likely to be found on Mars enhance our understanding of the degrees of hydration of various sulfates that should currently exist on Mars at various seasons and locations and during various atmospheric pressure and obliquity periods. Two sets of systematic experiments were described; one on hydrous Mg sulfates and the other on hydrous Fe<sup>3+</sup> sulfates. Also, their implications to Mars sulfates mineralogy were discussed.","language":"English","publisher":"Elsevier","doi":"10.1016/j.jseaes.2012.11.027","usgsCitation":"Chou, I., Seal, R., and Wang, A., 2013, The stability of sulfate and hydrated sulfate minerals near ambient conditions and their significance in environmental and planetary sciences: Journal of Asian Earth Sciences, v. 62, p. 734-758, https://doi.org/10.1016/j.jseaes.2012.11.027.","productDescription":"25 p.","startPage":"734","endPage":"758","numberOfPages":"25","ipdsId":"IP-035597","costCenters":[{"id":245,"text":"Eastern Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"links":[{"id":275633,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"62","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51fa31e8e4b076c3a8d8268f","contributors":{"authors":[{"text":"Chou, I-Ming 0000-0001-5233-6479 imchou@usgs.gov","orcid":"https://orcid.org/0000-0001-5233-6479","contributorId":882,"corporation":false,"usgs":true,"family":"Chou","given":"I-Ming","email":"imchou@usgs.gov","affiliations":[{"id":245,"text":"Eastern Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":473758,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Seal, Robert R.

Changes in chloride concentrations at depth within these aquifers were evaluated using sequential electromagnetic (EM) induction logs collected during 2004 through 2007 at seven multiple-well sites as deep as 268 m. Sequential EM logging is useful for identifying changes in groundwater quality through polyvinyl chloride-cased wells in intervals not screened by wells. These unscreened intervals represent more than 90% of the aquifer at the sites studied. Sequential EM logging suggested degrading groundwater quality in numerous thin intervals, typically between 1 and 7 m in thickness, especially in the northern part of the study area. Some of these intervals were unscreened by wells, and would not have been identified by traditional groundwater sample collection. Sequential logging also identified intervals with improving water quality—possibly due to groundwater management practices that have limited pumping and promoted artificial recharge. EM resistivity was correlated with chloride concentrations in sampled wells and in water from core material. Natural gamma log data were used to account for the effect of aquifer lithology on EM resistivity. Results of this study show that a sequential EM logging is useful for identifying and monitoring the movement of high-chloride water, having lower salinities and chloride concentrations than sea water, in aquifer intervals not screened by wells, and that increases in chloride in water from wells in the area are consistent with high-chloride water originating from the San Joaquin Delta rather than from the underlying saline aquifer.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ground Water","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1111/j.1745-6584.2012.00944.x","usgsCitation":"Metzger, L.F., and Izbicki, J., 2013, Electromagnetic-induction logging to monitor changing chloride concentrations: Ground Water, v. 51, no. 1, p. 108-121, https://doi.org/10.1111/j.1745-6584.2012.00944.x.","productDescription":"14 p.","startPage":"108","endPage":"121","numberOfPages":"14","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":282975,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":282970,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1745-6584.2012.00944.x"}],"country":"United States","state":"California","city":"Stockton","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -121.419736,37.887747 ], [ -121.419736,38.0583 ], [ -121.184019,38.0583 ], [ -121.184019,37.887747 ], [ -121.419736,37.887747 ] ] ] } } ] }","volume":"51","issue":"1","noUsgsAuthors":false,"publicationDate":"2012-05-18","publicationStatus":"PW","scienceBaseUri":"53cd574ee4b0b290850f7673","contributors":{"authors":[{"text":"Metzger, Loren F. 0000-0003-2454-2966 lmetzger@usgs.gov","orcid":"https://orcid.org/0000-0003-2454-2966","contributorId":1378,"corporation":false,"usgs":true,"family":"Metzger","given":"Loren","email":"lmetzger@usgs.gov","middleInitial":"F.","affiliations":[],"preferred":true,"id":491151,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Izbicki, John A. 0000-0003-0816-4408 jaizbick@usgs.gov","orcid":"https://orcid.org/0000-0003-0816-4408","contributorId":1375,"corporation":false,"usgs":true,"family":"Izbicki","given":"John A.","email":"jaizbick@usgs.gov","affiliations":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"preferred":false,"id":491150,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The objective of this report was to analyze recent feral ungulate surveys at the Hakalau Forest Unit to determine current pig abundance and distribution. Activity indices for feral pigs, consisting of the presence of fresh or intermediate sign at 422 stations, each with approximately 20 sample plots, were compiled for years 2010–2013. A calibrated model based on the number of pigs removed from one management unit and concurrent activity surveys was applied to estimate pig abundance in other management units. Although point estimates appeared to decrease from 489.1 (±105.6) in 2010 to 407.6 (±88.0) in 2013, 95% confidence intervals overlapped, indicating no significant change in pig abundance within all management units. Nonetheless, there were significant declines in pig abundance over the four-year period within management units 1, 6, and 7.

In this paper, we develop models of animal movement in relation to objects or fields in a landscape. We take a finite mixture modeling approach in which the component densities are conceptually related to different choices for movement in response to a landscape feature, and the mixing proportions are related to the probability of selecting each response as a function of one or more covariates. We combine particle swarm optimization and an Expectation-Maximization (EM) algorithm to obtain maximum likelihood estimates of the model parameters. We use this approach to analyze data for movement of three bobcats in relation to urban areas in southern California, USA. A behavioral interpretation of the models revealed similarities and differences in bobcat movement response to urbanization. All three bobcats avoided urbanization by moving either parallel to urban boundaries or toward less urban areas as the proportion of urban land cover in the surrounding area increased. However, one bobcat, a male with a dispersal-like large-scale movement pattern, avoided urbanization at lower densities and responded strictly by moving parallel to the urban edge. The other two bobcats, which were both residents and occupied similar geographic areas, avoided urban areas using a combination of movements parallel to the urban edge and movement toward areas of less urbanization. However, the resident female appeared to exhibit greater repulsion at lower levels of urbanization than the resident male, consistent with empirical observations of bobcats in southern California. Using the parameterized finite mixture models, we mapped behavioral states to geographic space, creating a representation of a behavioral landscape. This approach can provide guidance for conservation planning based on analysis of animal movement data using statistical models, thereby linking connectivity evaluations to empirical data.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Applications","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Ecological Society of America","publisherLocation":"Tempe, AZ","doi":"10.1890/12-0687.1","usgsCitation":"Tracey, J.A., Zhu, J., Boydston, E.E., Lyren, L.M., Fisher, R.N., and Crooks, K.R., 2013, Mapping behavioral landscapes for animal movement: a finite mixture modeling approach: Ecological Applications, v. 23, no. 3, p. 654-669, https://doi.org/10.1890/12-0687.1.","productDescription":"16 p.","startPage":"654","endPage":"669","numberOfPages":"16","ipdsId":"IP-041722","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":473994,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1890/12-0687.1","text":"Publisher Index Page"},{"id":294174,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":293974,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/12-0687.1"}],"volume":"23","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"541bf43de4b0e96537ddf76f","contributors":{"authors":[{"text":"Tracey, Jeff A. 0000-0002-1619-1054 jatracey@usgs.gov","orcid":"https://orcid.org/0000-0002-1619-1054","contributorId":5780,"corporation":false,"usgs":true,"family":"Tracey","given":"Jeff","email":"jatracey@usgs.gov","middleInitial":"A.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":501360,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Zhu, Jun","contributorId":73485,"corporation":false,"usgs":true,"family":"Zhu","given":"Jun","email":"","affiliations":[],"preferred":false,"id":501362,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Boydston, Erin E. 0000-0002-8452-835X eboydston@usgs.gov","orcid":"https://orcid.org/0000-0002-8452-835X","contributorId":1705,"corporation":false,"usgs":true,"family":"Boydston","given":"Erin","email":"eboydston@usgs.gov","middleInitial":"E.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":501358,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Lyren, Lisa M. llyren@usgs.gov","contributorId":2398,"corporation":false,"usgs":true,"family":"Lyren","given":"Lisa","email":"llyren@usgs.gov","middleInitial":"M.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":501359,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Fisher, Robert N. 0000-0002-2956-3240 rfisher@usgs.gov","orcid":"https://orcid.org/0000-0002-2956-3240","contributorId":1529,"corporation":false,"usgs":true,"family":"Fisher","given":"Robert","email":"rfisher@usgs.gov","middleInitial":"N.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":501357,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Crooks, Kevin R.","contributorId":51137,"corporation":false,"usgs":false,"family":"Crooks","given":"Kevin","email":"","middleInitial":"R.","affiliations":[{"id":6621,"text":"Colorado State University","active":true,"usgs":false}],"preferred":false,"id":501361,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

We have four objectives: (1) to describe key services in drylands, (2) to identify consequences of desertification to each service, (3) to explore the vulnerability of each service to future state-changes if existing threats intensify and new threats emerge, and (4) to determine threats expected to have the greatest future impact, and to provide potential actions for mitigation.

Such legislation includes, but is not limited to, the Forest Service Organic Administration Act of 1897 (16 U.S>C. 473-478, 479-482 and 551), National Park Service Organic Act of 1916 (U.S.C. Title 16, Secs. 1-4). Wilderness Act 1964 (P.L.88-577), National Environmental Policy Act of 1969 (P.L. 91-190), Endangered Species Act of 1973 (P.L. 91-205), National Forest Management Act of of 1976 (P.L. 94-588), and Federal Land Policy and Management Act of 1976 (P.L. 94-579). The acts establishing congressionally designated areas within southern Nevada, such as Lake Mead National Recreation Area, Spring Mountains National Restoration Area, and Desert National Wildlife Refuge, also contain guidelines for the management of these lands. These documents variously require preservation of natural and cultural resource and wilderness character, protection of species, and prevention of undesirable environmental effects from land management actions. These requirements must be met while allowing for multiple \"uses\" of certain public lands (e.g. recreation, ranching, resources extraction, renewable energy development, etc.) to the degree that they do no threaten preservation, protection, and prevention goals,. many considerations some into play in the development and implementation for land management plans and actions. The planning process requires a balancing act that sometimes pit one need or priority against another. When priorities can trump other needs can prioritized and receive disproportionate consideration. Overall, the management of public lands is a very complicated and sometime contentious process.</p>\n<br>\n<p>Science provides an objective way to help weigh quantifiable information and draw conclusions about the effects of past and potential future land management policies, decisions, and actions. When effectively integrated into adaptive management, science-based information can reduce uncertainties, increase knowledge, and improve decision making. However, the specific science information needed for effective management is often lacking or difficult to access or interpret. Science is typically reported in scientific journals as discrete units describing individual studies with other scientists as the primary audience. Translations of these studies an synthesis or multiple studies into formats that can be readily used in land management planning efforts are often lacking. Identifying and articulating the highest priority science and research needs is one of the primary purposes of the Southern Nevada Agency Partnership (SNAP; http://www.SNAP.gov) Science and Research Team (chapter 1; Turner and others 2009). The SNAP Science and Research Strategy (Strategy) calls for a synthesis report to be written every 5 years summarizing the state of knowledge, information gaps and management implications of scientific information as it relates to the SNAP Strategy goals (Turner and others 2009). This General Technical Report serves as the first SNAP Science and Research Synthesis Report (Synthesis Report) commissioned by the Science and Research Team. The Synthesis Report is mostly based on information form the peer-reviewed scientific literature, and is itself peer reviewed and constitutes a new contribution to the scientific literature. This final chapter addresses Sub-goal 2.3, which is to manage current and future authorized southern Nevada land uses in a manner that balances public need and ecosystem sustainability, and Sub-goal 2.5, which is to promote an effective conservation education and interpretation program to improve the quality of resources and enhance public use and enjoyment of southern Nevada public lands. It summarizes information form the previous chapters on what scientific information is known currently and what remains largely unknown, and it discusses how science can be used to make future management decisions that balances public needs and ecosystem sustainability.</p>","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"The Southern Nevada Agency Partnership science and research synthesis: Science to support land management in southern Nevada (General Technical Report RMRS-GTR-303)","largerWorkSubtype":{"id":1,"text":"Federal Government Series"},"language":"English","publisher":"U.S. Forest Service","publisherLocation":"Fort Collins, CO","usgsCitation":"Brooks, M.L., and Chambers, J., 2013, Science-based management of public lands in southern Nevada: General Technical Report RMRS-GTR-303, 7 p.","productDescription":"7 p.","startPage":"201","endPage":"207","numberOfPages":"7","ipdsId":"IP-042744","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":411219,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://www.fs.usda.gov/research/treesearch/44309","linkFileType":{"id":5,"text":"html"}},{"id":294541,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Nevada","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -114.62994356826636,\n              35.02392827573823\n            ],\n            [\n              -114.71108092890972,\n              36.05434128183754\n            ],\n            [\n              -114.1610398819929,\n              35.96903144947467\n            ],\n            [\n              -113.99956682074821,\n              39.38359318014548\n            ],\n            [\n              -120.06431672841825,\n              39.64524306073176\n            ],\n            [\n              -120.09127846963423,\n              38.90168971729281\n            ],\n            [\n              -114.62994356826636,\n              35.02392827573823\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54252ecde4b0e641df8a714f","contributors":{"authors":[{"text":"Brooks, Matthew L. 0000-0002-3518-6787 mlbrooks@usgs.gov","orcid":"https://orcid.org/0000-0002-3518-6787","contributorId":393,"corporation":false,"usgs":true,"family":"Brooks","given":"Matthew","email":"mlbrooks@usgs.gov","middleInitial":"L.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":500439,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Chambers, Jeanne C.","contributorId":75889,"corporation":false,"usgs":false,"family":"Chambers","given":"Jeanne C.","affiliations":[],"preferred":false,"id":500440,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Post-fire wind erosion studies have predominantly\nfocused on near-surface sediment transport and associated impacts such as on-site soil loss and site fertility. Downwind impacts, including air quality degradation and deposition of dust or contaminants, are also likely post-fire effects; however, quantitative field measurements of post-fire dust emissions are needed for assessment of these downwind risks. A wind erosion monitoring system was installed immediately following a desert sagebrush and grass wildfire in southeastern Idaho, USA to measure wind erosion from the burned landscape. This paper presents measurements of horizontal sediment flux and PM<sub>10</sub> vertical flux from the burned area. We determined threshold wind speeds and corresponding threshold friction velocities to be 6.0 and 20 m s<sup>-1</sup>, respectively, for the 4 months immediately following the fire\nand 10 and 0.55 m s<sup>-1</sup> for the following spring months. Several major wind erosion events were measured in the months following the July 2010 Jefferson Fire. The largest wind erosion event occurred in early September 2010 and produced 1495 kg m<sup>-1</sup> of horizontal sediment transport within the first 2 m\nabove the soil surface, had a maximum PM<sub>10</sub> vertical flux of 100 mg m<sup>-2</sup> s<sup>-1</sup>, and generated a large dust plume that was visible in satellite imagery. The peak PM<sub>10</sub> concentration measured on-site at a height of 2 m in the downwind portion of the burned area was 690 mg m<sup>-3</sup>. Our results indicate that wildfire can convert a relatively stable landscape into one that is a major dust source.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Aeolian Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.aeolia.2012.10.003","usgsCitation":"Wagenbrenner, N.S., Germino, M., Lamb, B.K., Robichaud, P., and Foltz, R.B., 2013, Wind erosion from a sagebrush steppe burned by wildfire: measurements of PM<sub>10</sub> and total horizontal sediment flux: Aeolian Research, v. 10, p. 25-36, https://doi.org/10.1016/j.aeolia.2012.10.003.","productDescription":"12 p.","startPage":"25","endPage":"36","numberOfPages":"12","ipdsId":"IP-041371","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":275751,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":275750,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.aeolia.2012.10.003"}],"country":"United States","state":"Idaho","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -112.602151,43.414487 ], [ -112.602151,43.656388 ], [ -112.071571,43.656388 ], [ -112.071571,43.414487 ], [ -112.602151,43.414487 ] ] ] } } ] }","volume":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51fb7555e4b04b00e3d7856f","contributors":{"authors":[{"text":"Wagenbrenner, Natalie S.","contributorId":70685,"corporation":false,"usgs":true,"family":"Wagenbrenner","given":"Natalie","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":481776,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Germino, Matthew J.","contributorId":50029,"corporation":false,"usgs":true,"family":"Germino","given":"Matthew J.","affiliations":[],"preferred":false,"id":481775,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lamb, Brian K.","contributorId":30539,"corporation":false,"usgs":true,"family":"Lamb","given":"Brian","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":481773,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Robichaud, Peter R.","contributorId":102782,"corporation":false,"usgs":true,"family":"Robichaud","given":"Peter R.","affiliations":[],"preferred":false,"id":481777,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Foltz, Randy B.","contributorId":35636,"corporation":false,"usgs":true,"family":"Foltz","given":"Randy","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":481774,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Regional and local differences within Peregrine Falcons were sufficiently variable that ∼75 subspecies have been described; many were subsumed, and currently 19 are generally recognized. We used sequence information from the control region of the mitochondrial genome to test for concordance between genetic structure and representatives of 12 current subspecies and from two areas where subspecies distributions overlap. Haplotypes were broadly shared among subspecies, and all geographic locales shared a widely distributed common haplotype (FalconCR2). Haplotypes were distributed in a star-like phylogeny, consistent with rapid expansion of a recently derived species, with observed genetic patterns congruent with incomplete lineage sorting and/or differential rates of evolution on morphology and neutral genetic characters. Hierarchical analyses of molecular variance did not uncover genetic partitioning at the continental level, despite strong population-level structure (<i>F</i>ST = 0.228). Similar analyses found weak partitioning, albeit significant, among subspecies (<i>F</i>CT = 0.138).

Unlike foraging shorebirds, Mallards do not avoid incoming swashes. Instead, the incoming swash lifts and deposits them down the beach. Shorebirds and diving ducks commonly feed on sand crabs, but sand crabs appear to be a novel behavior and food source for Mallards. Previous surveys of beaches did not report foraging Mallards on regional beaches, whereas foraging Mallards were common in contemporary (recent) surveys and anecdotal reports. Observations of this potentially new behavior were separated by as much as 1,300 km, indicating that this was not a local phenomenon. Mallards foraged singly, in pairs, and in flocks. An expansion of diet to sand crabs carries risks of exposure to surf, human disturbance, high salt intake, and transmission of acanthocephalan and trematode parasites for Mallards but has the benefit of providing a dependable source of animal protein.","language":"English","publisher":"Wilson Ornithological Society","publisherLocation":"Lawrence, KS","doi":"10.1676/12-141.1","usgsCitation":"Lafferty, K.D., McLaughlin, J.P., and Dugan, J.E., 2013, Novel foraging in the swash zone on Pacific sand crabs (<i>Emerita analoga</i>, Hippidae) by mallards: Wilson Journal of Ornithology, v. 125, no. 2, p. 423-426, https://doi.org/10.1676/12-141.1.","productDescription":"4 p.","startPage":"423","endPage":"426","numberOfPages":"4","ipdsId":"IP-041913","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":294168,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":294024,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1676/12-141.1"}],"volume":"125","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"541bf441e4b0e96537ddf797","contributors":{"authors":[{"text":"Lafferty, Kevin D. 0000-0001-7583-4593 klafferty@usgs.gov","orcid":"https://orcid.org/0000-0001-7583-4593","contributorId":1415,"corporation":false,"usgs":true,"family":"Lafferty","given":"Kevin","email":"klafferty@usgs.gov","middleInitial":"D.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":501523,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McLaughlin, John P.","contributorId":17153,"corporation":false,"usgs":true,"family":"McLaughlin","given":"John","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":501524,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Dugan, Jenifer E.","contributorId":66189,"corporation":false,"usgs":true,"family":"Dugan","given":"Jenifer","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":501525,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Recognized source rocks for the oil families include the (1) Eocene Kreyenhagen Formation, (2) Eocene Tumey Formation, (3–4) upper and lower parts of the Miocene Monterey Formation (Buttonwillow depocenter), and (5–6) upper and lower parts of the Miocene Monterey Formation (Tejon depocenter).</p>\n<br/>\n<p>Ascendant hierarchical clustering identifies 22 oil families in the basin as corroborated by independent data, such as carbon-isotope ratios, sample location, reservoir unit, and thermal maturity maps from a three-dimensional basin and petroleum system model. Five families originated from the Eocene Kreyenhagen Formation source rock, and three families came from the overlying Eocene Tumey Formation. Fourteen families migrated from the upper and lower parts of the Miocene Monterey Formation source rocks within the Buttonwillow and Tejon depocenters north and south of the Bakersfield arch. The Eocene and Miocene families show little cross-stratigraphic migration because of seals within and between the source rocks. The data do not exclude the possibility that some families described as originating from the Monterey Formation actually came from source rock in the Temblor Formation.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"AAPG Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Association of Petroleum Geologists","publisherLocation":"Tulsa, OK","doi":"10.1306/05231212018","usgsCitation":"Peters, K., Coutrot, D., Nouvelle, X., Ramos, L.S., Rohrback, B.G., Magoon, L.B., and Zumberge, J.E., 2013, Chemometric differentiation of crude oil families in the San Joaquin Basin, California: AAPG Bulletin, v. 97, no. 1, p. 103-143, https://doi.org/10.1306/05231212018.","productDescription":"41 p.","startPage":"103","endPage":"143","numberOfPages":"41","costCenters":[],"links":[{"id":291324,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":291323,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1306/05231212018"}],"volume":"97","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"57f7f37de4b0bc0bec0a09d7","contributors":{"authors":[{"text":"Peters, Kenneth E.","contributorId":10897,"corporation":false,"usgs":true,"family":"Peters","given":"Kenneth E.","affiliations":[],"preferred":false,"id":497091,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Coutrot, Delphine","contributorId":54901,"corporation":false,"usgs":true,"family":"Coutrot","given":"Delphine","email":"","affiliations":[],"preferred":false,"id":497094,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Nouvelle, Xavier","contributorId":52089,"corporation":false,"usgs":true,"family":"Nouvelle","given":"Xavier","email":"","affiliations":[],"preferred":false,"id":497093,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ramos, L.

Most malaria models to date assume constant or linear responses of mosquito and parasite life-history traits to temperature, predicting optimal transmission at 31 °C. These models are at odds with field observations of transmission dating back nearly a century. We build a model with more realistic ecological assumptions about the thermal physiology of insects. Our model, which includes empirically derived nonlinear thermal responses, predicts optimal malaria transmission at 25 °C (6 °C lower than previous models). Moreover, the model predicts that transmission decreases dramatically at temperatures > 28 °C, altering predictions about how climate change will affect malaria. A large data set on malaria transmission risk in Africa validates both the 25 °C optimum and the decline above 28 °C. Using these more accurate nonlinear thermal-response models will aid in understanding the effects of current and future temperature regimes on disease transmission.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecology Letters","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Blackwell Science","publisherLocation":"Oxford","doi":"10.1111/ele.12015","usgsCitation":"Mordecai, E.A., Paaijmans, K.P., Johnson, L., Balzer, C., Ben-Horin, T., de Moor, E., McNally, A., Pawar, S., Ryan, S.J., Smith, T.C., and Lafferty, K.D., 2013, Optimal temperature for malaria transmission is dramaticallylower than previously predicted: Ecology Letters, v. 16, no. 1, p. 22-30, https://doi.org/10.1111/ele.12015.","productDescription":"9 p.","startPage":"22","endPage":"30","numberOfPages":"9","ipdsId":"IP-040879","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":294164,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":294056,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/ele.12015"}],"volume":"16","issue":"1","noUsgsAuthors":false,"publicationDate":"2012-10-11","publicationStatus":"PW","scienceBaseUri":"541bf445e4b0e96537ddf7c2","contributors":{"authors":[{"text":"Mordecai, Eerin A.","contributorId":46882,"corporation":false,"usgs":true,"family":"Mordecai","given":"Eerin","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":501592,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Paaijmans, Krijin P.","contributorId":83850,"corporation":false,"usgs":true,"family":"Paaijmans","given":"Krijin","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":501597,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Johnson, Leah R.","contributorId":83382,"corporation":false,"usgs":true,"family":"Johnson","given":"Leah R.","affiliations":[],"preferred":false,"id":501596,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Balzer, Christian","contributorId":41279,"corporation":false,"usgs":true,"family":"Balzer","given":"Christian","email":"","affiliations":[],"preferred":false,"id":501591,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ben-Horin, Tal","contributorId":58137,"corporation":false,"usgs":false,"family":"Ben-Horin","given":"Tal","email":"","affiliations":[],"preferred":false,"id":501595,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"de Moor, Emily","contributorId":48021,"corporation":false,"usgs":true,"family":"de Moor","given":"Emily","email":"","affiliations":[],"preferred":false,"id":501593,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"McNally, Amy","contributorId":53225,"corporation":false,"usgs":true,"family":"McNally","given":"Amy","affiliations":[],"preferred":false,"id":501594,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Pawar, Samraat","contributorId":22622,"corporation":false,"usgs":true,"family":"Pawar","given":"Samraat","email":"","affiliations":[],"preferred":false,"id":501590,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Ryan, Sadie J.","contributorId":102738,"corporation":false,"usgs":true,"family":"Ryan","given":"Sadie","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":501599,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Smith, Thomas C.","contributorId":101139,"corporation":false,"usgs":true,"family":"Smith","given":"Thomas","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":501598,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Lafferty, Kevin D. 0000-0001-7583-4593 klafferty@usgs.gov","orcid":"https://orcid.org/0000-0001-7583-4593","contributorId":1415,"corporation":false,"usgs":true,"family":"Lafferty","given":"Kevin","email":"klafferty@usgs.gov","middleInitial":"D.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":501589,"contributorType":{"id":1,"text":"Authors"},"rank":11}]}}

The diverse and robust vegetative cover that developed in the first year post-reconstruction experienced significant decimation in the second year, after the protective fencing was removed, and remained suppressed throughout the five-year study period.  In June 2009 a herbivory study was initiated to document the impacts of herbivory by resident and nonmigratory Canada geese (Branta canadensis) to vegetation at Kingman Marsh.  Sixteen modules consisting of paired fenced plots and unfenced control plots were constructed.  Eight of the modules were installed in vegetated portions of the restoration site that had been protected over time by pre-existing fencing, while the remaining eight modules were placed in portions of the site that had not been protected over time and were basically unvegetated at the start of the experiment.  Exclosure fencing was sufficiently elevated from the substrate level to allow access to other herbivores such as fish and turtles, while hopefully excluding mature Canada geese.  The study was designed with an initial exclosure elevation of 20 cm.  This elevation was chosen based on the literature, as adequate to exclude mature Canada geese, while maximizing access to other herbivores such as fish and turtles.</p>\n<br>\n<p>Repeated measures analysis of variance (ANOVA) was used to analyze the differences between paired fenced and unfenced control plots for a number of variables including total vegetative cover.  Differences in total vegetative cover were not statistically significant for the baseline data collected in June 2009.  By contrast, two months after the old protective fencing was removed from the initially-vegetated areas to allow Canada geese access to the unfenced control plots, total vegetative cover had declined dramatically in the initially-vegetated unfenced control plots, and differences between paired fenced and unfenced control plots were statistically significant.  These differences have remained steady and significant throughout the remainder of these first three years of the study.</p>\n<br>\n<p>Total vegetative cover has followed a somewhat different path in the initially-unvegetated modules, where cover in the fenced plots did not significantly exceed cover in the unfenced control plots until the August 2010 sampling event.  In spite of the slow start in the initially-unvegetated modules, differences between paired fenced plots and unfenced control plots have remained significant and even increased significantly over time.  This indicates that total vegetative cover in the initially-unvegetated fenced plots and unfenced control plots is continuing to diverge over time as vegetation increases in the protected plots compared to the basically unvegetated unfenced control plots.</p>\n<br>\n<p>Total vegetative cover has been composed almost entirely of native species during the first three years of the study, with cover by exotics averaging less than 1% during each sampling event.</p>\n<br>\n<p>Species richness did not differ significantly between fenced plots and unfenced control plots during 2009, the first year of the study.  Since August 2010, species richness has remained significantly greater in the fenced plots than in the unfenced control plots.  These differences have remained relatively steady over time for both the initially-vegetated and initially unvegetated modules.</p>    \n<br>\n<p>During the study it became apparent that our elevated fence plots were more accessible to mature \ngeese than we had expected. Even after lowering the exclosure fencing to 15 cm in 2010 and 10 \ncm in 2011, we documented geese inside exclosures in both years. Nonetheless the data indicate \nthat even at 10 cm, we have limited the numbers of mature geese entering the fenced plots, rather \nthan totally preventing their access through low spots in the uneven substrate surface. At an \nexclosure elevation of 10 cm and with a soft, mucky substrate, we are assuming that non-goose \nherbivores such as fish and turtles still have free access to the fenced plots. Annual wildrice \n(Zizania aquatica), known from previous studies to be especially palatable to Canada geese, has \nseen the greatest impact from partial access to the fenced plots by mature geese, moving from an \noverwhelming dominant in the initially-vegetated plots to a minor presence there by August \n2011. Interestingly, pickerelweed (Pontederia cordata), also known to be highly palatable to \nCanada geese, has so far shown only minor herbivory in the fenced plots. By August 2011, \npickerelweed had actually increased to significantly greater cover levels in the fenced plots \ncompared to the unfenced control plots.</p>\n<br>\n<p>In conclusion, the first three years of data document that vegetation exposed to full herbivory by resident and nonmigratory Canada geese for three years in the unfenced control plots showed significantly lower total vegetative cover and species richness compared to the vegetation in the fenced plots, which experienced reduced herbivory by resident and nonmigratory Canada geese. These effects were documented for modules located in both initially-vegetated and initially-unvegetated habitats.</p>","language":"English","publisher":"National Park Service","publisherLocation":"Washington, D.C.","usgsCitation":"Krafft, C., Hatfield, J., and Hammerschlag, R.S., 2013, Effects of Canada goose herbivory on the tidal freshwater wetlands in Anacostia Park, 2009-2011, viii, 36 p.","productDescription":"viii, 36 p.","numberOfPages":"47","temporalStart":"2009-01-01","temporalEnd":"2011-12-31","ipdsId":"IP-055779","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":287678,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":287677,"type":{"id":11,"text":"Document"},"url":"https://www.pwrc.usgs.gov/prodabs/pubpdfs/7996_Krafft.pdf"}],"country":"United States","state":"Maryland","city":"Washington, D.C.","otherGeospatial":"Anacostia Park","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -77.0035716,38.8643463 ], [ -77.0035716,38.8710952 ], [ -76.9885262,38.8710952 ], [ -76.9885262,38.8643463 ], [ -77.0035716,38.8643463 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53870566e4b0aa26cd7b539a","contributors":{"authors":[{"text":"Krafft, Cairn C.","contributorId":60364,"corporation":false,"usgs":true,"family":"Krafft","given":"Cairn C.","affiliations":[],"preferred":false,"id":493357,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hatfield, Jeffrey S. jhatfield@usgs.gov","contributorId":151,"corporation":false,"usgs":true,"family":"Hatfield","given":"Jeffrey S.","email":"jhatfield@usgs.gov","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":493356,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hammerschlag, Richard S.","contributorId":67206,"corporation":false,"usgs":true,"family":"Hammerschlag","given":"Richard","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":493358,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

One conventional assessment unit extending from south Texas to the Florida panhandle was defined: the Fredericksburg-Buda Carbonate Platform-Reef Gas and Oil assessment unit. Assessed strata range in age from Early Cretaceous Albian to Late Cretaceous Cenomanian. The assessment was based on a geologic model that incorporated the Upper Jurassic–Cretaceous–Tertiary Composite Total Petroleum System of the Gulf of Mexico Basin. The following factors were evaluated to define the assessment unit and estimate undiscovered oil and gas resources: potential source rocks, hydrocarbon migration, reservoir porosity and permeability, traps and seals, structural features, depositional framework, and potential for water washing of hydrocarbons near outcrop areas. Analysis of the production history of discovered reservoirs and well data within the assessment unit was also essential for estimating the numbers and sizes of undiscovered oil and gas reservoirs within the assessment unit.

That study, along with numerous other studies, has shown that the amount of gas stored as methane hydrates in the world greatly exceeds the volume of known conventional gas resources. However, gas hydrates represent both a scientific and technical challenge and much remains to be learned about their characteristics and occurrence in nature. Methane hydrate research in recent years has mostly focused on: (1) documenting the geologic parameters that control the occurrence and stability of gas hydrates in nature, (2) assessing the volume of natural gas stored within various gas hydrate accumulations, (3) analyzing the production response and characteristics of methane hydrates, (4) identifying and predicting natural and induced environmental and climate impacts of natural gas hydrates, and (5) analyzing the effects of methane hydrate on drilling safety.</p><p>Methane hydrates are naturally occurring crystalline substances composed of water and gas, in which a solid water-­‐lattice holds gas molecules in a cage-­‐like structure. The gas and water becomes a solid under specific temperature and pressure conditions within the Earth, called the hydrate stability zone. Other factors that control the presence of methane hydrate in nature include the source of the gas included within the hydrates, the physical and chemical controls on the migration of gas with a sedimentary basin containing methane hydrates, the availability of the water also included in the hydrate structure, and the presence of a suitable host sediment or “reservoir”. The geologic controls on the occurrence of gas hydrates have become collectively known as the “methane hydrate petroleum system”, which has become the focus of numerous hydrate research programs.</p><p><br></p><p>Recognizing the importance of methane hydrate research and the need for a coordinated effort, the U.S. Congress enacted Public Law 106-­‐193, the Methane Hydrate Research and Development Act of 2000. This Act called for the Secretary of Energy to begin a methane hydrate research and development program in consultation with other U.S. federal agencies. At the same time a new methane hydrate research program had been launched in Japan by the Ministry of International Trade and Industry to develop plans for a methane hydrate exploratory drilling project in the Nankai Trough. Since this early start we have seen other countries including India, China, Canada, and the Republic of Korea establish large gas hydrate research and development programs. These national led efforts have also included the investment in a long list of important scientific research drilling expeditions and production test studies that have provided a wealth of information on the occurrence of methane hydrate in nature.

For the most part methane hydrate research expeditions carried out by the ODP and IODP provided the foundation for our scientific understanding of gas hydrates. The methane hydrate research efforts under ODP-­‐IODP have mostly dealt with the assessment of the geologic controls on the occurrence of gas hydrate, with a specific goal to study the role methane hydrates may play in the global carbon cycle.</p><p><br></p><p>Over the last 10 years, national led methane hydrate research programs, along with industry interest have led to the development and execution of major methane hydrate production field test programs. Two of the most important production field testing programs have been conducted at the Mallik site in the Mackenzie River Delta of Canada and in the Eileen methane hydrate accumulation on the North Slope of Alaska. Most recently we have also seen the completion of the world’s first marine methane hydrate production test in the Nankai Trough in the offshore of Japan. Industry interest in gas hydrates has also included important projects that have dealt with the assessment of geologic hazards associated with the presence of hydrates.</p><p><br></p><p>The scientific drilling and associated coring, logging, and borehole monitoring technologies developed in the long list of methane hydrate related field studies are one of the most important developments and contributions associated with methane hydrate research and development activities. Methane hydrate drilling has been conducted from advanced scientific drilling platforms like the JOIDES Resolution and the D/V Chikyu, which feature highly advanced integrated core laboratories and borehole logging capabilities. Hydrate research drilling has also included the use of a wide array of industry, geotechnical and multi-­‐service ships. All of which have been effectively used to collect invaluable geologic and engineering data on the occurrence of methane hydrates throughout the world. Technologies designed specifically for the collection and analysis of undisturbed methane hydrate samples have included the development of a host of pressure core systems and associated specialty laboratory apparatus. The study and use of both wireline conveyed and logging-­‐while-­‐drilling technologies have also contributed greatly to our understanding of the in-­‐situ nature of hydrate-­‐bearing sediments. Recent developments in borehole instrumentation specifically designed to monitor changes associated with hydrates in nature through time or to evaluate the response of hydrate accumulations to production have also contributed greatly to our understanding of the complex nature and evolution of methane hydrate systems.</p><p><br></p><p>Our understanding of how methane hydrates occur and behave in nature is still growing and evolving – we do not yet know if methane hydrates can be economically produced, nor do we know fully the role of hydrates as an agent of climate change or as a geologic hazard. But it is known for certain that scientific drilling has contributed greatly to our understanding of hydrates in nature and will continue to be a critical source of the information to advance our understanding of methane hydrates.</p>","language":"English","publisher":"Consortium for Ocean Leadership","publisherLocation":"Washington D.C.","collaboration":"Report prepared for the U.S. Department of Energy - National Energy Technology Laboratory, by the Consortium for Ocean Leadership","usgsCitation":"Collett, T., Bahk, J., Frye, M., Goldberg, D., Husebo, J., Koh, C., Malone, M., Shipp, C., and Torres, M., 2013, Historical methane hydrate project review, Part 1: 110 p.; Part 2: 32 p.; Part 3: 42 p.","productDescription":"Part 1: 110 p.; Part 2: 32 p.; Part 3: 42 p.","numberOfPages":"187","ipdsId":"IP-045213","costCenters":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":287820,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":287819,"type":{"id":7,"text":"Companion Files"},"url":"https://oceanleadership.org/wp-content/uploads/COL_DOE_GH_Review-part3_Final.pdf"},{"id":281602,"type":{"id":15,"text":"Index Page"},"url":"https://oceanleadership.org/scientific-programs/methane-hydrate-field-program/"},{"id":287817,"type":{"id":11,"text":"Document"},"url":"https://oceanleadership.org/wp-content/uploads/COL_DOE_GH_Review-part1_Final.pdf"},{"id":287818,"type":{"id":7,"text":"Companion Files"},"url":"https://oceanleadership.org/wp-content/uploads/COL_DOE_GH_Review-part2_Final.pdf"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53885700e4b0318b93124ab4","contributors":{"authors":[{"text":"Collett, Timothy 0000-0002-7598-4708","orcid":"https://orcid.org/0000-0002-7598-4708","contributorId":97008,"corporation":false,"usgs":true,"family":"Collett","given":"Timothy","affiliations":[],"preferred":false,"id":489454,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bahk, Jang-Jun","contributorId":12781,"corporation":false,"usgs":true,"family":"Bahk","given":"Jang-Jun","email":"","affiliations":[],"preferred":false,"id":489446,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Frye, Matt","contributorId":60543,"corporation":false,"usgs":true,"family":"Frye","given":"Matt","email":"","affiliations":[],"preferred":false,"id":489451,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Goldberg, Dave","contributorId":57376,"corporation":false,"usgs":true,"family":"Goldberg","given":"Dave","affiliations":[],"preferred":false,"id":489450,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Husebo, Jarle","contributorId":77851,"corporation":false,"usgs":true,"family":"Husebo","given":"Jarle","email":"","affiliations":[],"preferred":false,"id":489452,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Koh, Carolyn","contributorId":42883,"corporation":false,"usgs":true,"family":"Koh","given":"Carolyn","email":"","affiliations":[],"preferred":false,"id":489449,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Malone, Mitch","contributorId":34437,"corporation":false,"usgs":true,"family":"Malone","given":"Mitch","email":"","affiliations":[],"preferred":false,"id":489447,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Shipp, Craig","contributorId":40522,"corporation":false,"usgs":true,"family":"Shipp","given":"Craig","email":"","affiliations":[],"preferred":false,"id":489448,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Torres, Marta","contributorId":86477,"corporation":false,"usgs":true,"family":"Torres","given":"Marta","affiliations":[],"preferred":false,"id":489453,"contributorType":{"id":1,"text":"Authors"},"rank":9}]}}

Reproductive tiller density and visual obstruction increased 2 yr after treatment with two herbicide treatments applied either early and middle season or early and late season, but it was prevented with burning and mowing prior to herbicide application. With the exception of three herbicide applications, combining burning or mowing with herbicide applications provided more effective control of yellow bluestem than any individual herbicide applications.

Sustainable or \"healthy\" ecosystems supply clean air, water and habitat for a diverse array of plants and animals. As described in Chapter 1, sustainable ecosystems retain characteristic processes like hydrological flux and storage, geomorphic processes, biogeochemical cycling and storage, biological activity and productivity, and population regeneration and reproduction over the normal cycle of disturbance events (modified from Chapin and others 1996 and Christensen and others 1996). Ecological restoration of stressed or disturbed ecosystems in an integral part of managing for sustainable ecosystems. The Society of Ecological Restoration International (SERI) defines ecological restoration as the process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed (SERI 2004).</p>\n<br>\n<p>Many of the southern Nevada's ecosystems are being subjected to anthropogenic stressors that span global, regional, and local scales (Chapter 2)., and are crossing ecological thresholds to new alternative states (Chapter 4 and Chapter 5). These alternative states often represent novel communities with disturbance regimes that differ significantly from historic conditions. Past management and restoration goals often focused on returning ecosystems to pre-disturbance conditions (Harris and others 2006). This approach assumes stable or equilibrium conditions and ignores changes in ecosystems processes due to land uses, increases in CO<sub>2</sub> concentrations, and climate change. A more realistic approach is to base management and restoration goals on the current potential of an ecosystem to support a given set of ecological conditions, and on the likelihood of future change due to warming climate (Harris and others 2006). This approach requires understanding ecosystem resilience to anthropogenic disturbance and climate change, the alternative states that exist for ecosystems, and the factors that result in threshold crossing (Bestelmeyer and others 2009; Hobbs and Harris 2001; Stingham and others 2003; Whisemnant 1999). It also requires the ability to predict how climate is likely to influence ecosystems in the future (Harris and others 2006).</p>\n<br>\n<p>This chapter addresses the restoration aspects of Sub-goal 1.3 in the SNAP Science Research Strategy which is to restore and sustain proper function of southern Nevada's watersheds and landscapes (able 1.3; Turner and others 2009). The effects of global, regional and local stresses on southern Nevada ecosystems are presented in Chapter 2. Here, we discuss appropriate objectives and develop guidelines for maintaining and restoring southern Nevada ecosystems. We then discuss the differences in ecological resilience to stress and disturbance and resistance to invasive species in southern Nevada ecosystems and describe restoration and management approaches for the different ecosystem types. We conclude with knowledge gaps and management implications.</p>","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"The Southern Nevada Agency Partnership science and research synthesis: Science to support land management in southern Nevada (General Technical Report RMRS-GTR-303)","largerWorkSubtype":{"id":1,"text":"Federal Government Series"},"language":"English","publisher":"U.S. Forest Service","publisherLocation":"Fort Collins, CO","usgsCitation":"Chambers, J., Pendleton, B.K., Sada, D.W., Ostoja, S.M., and Brooks, M.L., 2013, Maintaining and restoring sustainable ecosystems in southern Nevada: General Technical Report RMRS-GTR-303, 30 p.","productDescription":"30 p.","startPage":"125","endPage":"154","numberOfPages":"30","ipdsId":"IP-037932","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":294532,"rank":2,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":294531,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://www.fs.fed.us/rm/pubs/rmrs_gtr303.html"}],"country":"United States","state":"Nevada","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -114.62994356826636,\n              35.02392827573823\n            ],\n            [\n              -114.71108092890972,\n              36.05434128183754\n            ],\n            [\n              -114.1610398819929,\n              35.96903144947467\n            ],\n            [\n              -113.99956682074821,\n              39.38359318014548\n            ],\n            [\n              -120.06431672841825,\n              39.64524306073176\n            ],\n            [\n              -120.09127846963423,\n              38.90168971729281\n            ],\n            [\n              -114.62994356826636,\n              35.02392827573823\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54252ec0e4b0e641df8a7085","contributors":{"authors":[{"text":"Chambers, Jeanne C.","contributorId":75889,"corporation":false,"usgs":false,"family":"Chambers","given":"Jeanne C.","affiliations":[],"preferred":false,"id":500456,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pendleton, Burton K.","contributorId":107187,"corporation":false,"usgs":true,"family":"Pendleton","given":"Burton","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":500457,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Sada, Donald W.","contributorId":20673,"corporation":false,"usgs":true,"family":"Sada","given":"Donald","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":500455,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ostoja, Steven M. sostoja@usgs.gov","contributorId":3039,"corporation":false,"usgs":true,"family":"Ostoja","given":"Steven","email":"sostoja@usgs.gov","middleInitial":"M.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true},{"id":33665,"text":"USDA California Climate Hub, UC Davis","active":true,"usgs":false}],"preferred":false,"id":500454,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Brooks, Matthew L. 0000-0002-3518-6787 mlbrooks@usgs.gov","orcid":"https://orcid.org/0000-0002-3518-6787","contributorId":393,"corporation":false,"usgs":true,"family":"Brooks","given":"Matthew","email":"mlbrooks@usgs.gov","middleInitial":"L.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":500453,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}
