The chemistry of submillimeter thick, buff-colored veneers reflects multiple processes at work since the establishment of the current plains surface. Veneer composition is dominated by the mixing of silicate-rich dust and sulfate-rich outcrop surface, but it has also been influenced by mineral precipitation, including NaCl, and possibly by limited physical or chemical weathering of sulfate minerals. Competing processes of chemical alteration (perhaps mediated by thin films of water or water vapor beneath blanketing soils) and sandblasting of exposed outcrop surfaces determine the current distribution of veneers. Dark-toned rinds several millimeters thick reflect more extensive surface alteration but also indicate combined dust admixture, halite precipitation, and possible minor sulfate removal. Cemented fracture fills that are differentially resistant to erosion occur along the margins of linear fracture systems possibly related to impact. These appear to reflect limited groundwater activity along the margins of fractures, cementing mechanically introduced fill derived principally from outcrop rocks. The limited thickness and spatial distribution of these three features suggest that aqueous activity has been rare and transient or has operated at exceedingly low rates during the protracted interval since outcropping Meridiani strata were exposed on the plains surface.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geophysical Research E: Planets","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Geophysical Union","publisherLocation":"Washington, D.C.

The Navcams are a panchromatic stereoscopic imaging system built using identical charge-coupled device (CCD) detectors and nearly identical electronics boards as the other cameras on the MER spacecraft. Previous calibration efforts were primarily focused on providing a detailed geometric calibration in line with the principal function of the Navcams, to provide data for the MER navigation team. This paper provides a detailed description of a new Navcam calibration pipeline developed to provide an absolute radiometric calibration that we estimate to have an absolute accuracy of 10% and a relative precision of 2.5%. Our calibration pipeline includes steps to model and remove the bias offset, the dark current charge that accumulates in both the active and readout regions of the CCD, and the shutter smear. It also corrects pixel-to-pixel responsivity variations using flat-field images, and converts from raw instrument-corrected digital number values per second to units of radiance (W m-2 nm-1 sr-1), or to radiance factor (I/F). We also describe here the initial results of two applications where radiance-calibrated Navcam data provide unique information for surface photometric and atmospheric aerosol studies.

However, climate warming is thawing permafrost in many areas leading to failures in soil structure called thermokarst. An extensive survey of a 600 km2 area in and around the Toolik Lake Natural Research Area (TLNRA) revealed at least 34 thermokarst features, two thirds of which were new since ???1980 when a high resolution aerial survey of the area was done. Most of these thermokarst features were associated with headwater streams or lakes. We have measured significantly increased sediment and nutrient loading from thermokarst features to streams in two well-studied locations near the TLNRA. One small thermokarst gully that formed in 2003 on the Toolik River in a 0.9 km2 subcatchment delivered more sediment to the river than is normally delivered in 18 years from 132 km2 in the adjacent upper Kuparuk River basin (a long-term monitoring reference site). Ammonium, nitrate, and phosphate concentrations downstream from a thermokarst feature on Imnavait Creek increased significantly compared to upstream reference concentrations and the increased concentrations persisted over the period of sampling (1999-2005). The downstream concentrations were similar to those we have used in a long-term experimental manipulation of the Kuparuk River and that have significantly altered the structure and function of that river. A subsampling of other thermokarst features from the extensive regional survey showed that concentrations of ammonium, nitrate, and phosphate were always higher downstream of the thermokarst features. Our previous research has shown that even minor increases in nutrient loading stimulate primary and secondary production. However, increased sediment loading could interfere with benthic communities and change the responses to increased nutrient delivery. Although the terrestrial area impacted by thermokarsts is limited, the aquatic habitat altered by these failures can be extensive. If warming in the Arctic foothills accelerates thermokarst formation, there may be substantial and wide-spread impacts on arctic stream ecosystems that are currently poorly understood.

Observations of thermodynamic variables and CO2 mixing ratio as well as vertical profiles of the turbulent fluxes are used to retrieve the contribution of the budget terms in the scalar conservation equation. On the basis of the daytime evolution of turbulent fluxes, we calculate the budget terms by assuming that turbulent fluxes follow a linear profile with height. This assumption is carefully tested and the deviation ftom linearity is quantified. The budget calculation allows us to assess the importance of advection of heat and CO2 during day hours for three selected days. It is found that, under nonadvective conditions, the diurnal variability of temperature and CO2 is well reproduced from the flux divergence measurements. Consequently, the vertical transport due to the turbulent flux plays a major role in the daytime evolution of both scalars and the advection is a relatively small contribution. During the analyzed days with a strong contribution of advection of either heat or carbon dioxide, the flux divergence is still an important contribution to the budget. For heat, the quantification of the advection contribution is in close agreement with results from a numerical model.

The concomitant yield of organic carbon (OC) associated with this class of rivers has also been shown to be significant and compositionally unique. We report here excessively high loadings of polycyclic aromatic hydrocarbons (PAHs), lignin, and levoglucosan, discharged from the Santa Clara River into the Santa Barbara Channel. The abundance of PAHs, levoglucosan, and lignin in Santa Barbara Channel sediments ranged from 201.7 to 1232.3 ng gdw-1, 1.3 to 6.9 ??g gdw-1, and 0.3 to 2.2 mg per 100 mg of the sedimentary OC, respectively. Assuming a constant rate of sediment accumulation, the annual fluxes of PAHs, levoglucosan, and lignin, to the Santa Barbara Channel were respectively, 885.5 ?? 170.2 ng cm-2 a-1, 3.5 ?? 1.9 ??g cm-2 a-1 and 1.4 ?? 0.3 mg per 100 mg OC cm-2 a-1, over ???30 years. The close agreement between PAHs, levoglucosan, and lignin abundance suggests that the depositional flux of these compounds is largely biomass combustion-derived. To that end, use of the Santa Clara River as a model for SMRs suggests this class of rivers may be one of the largest contributors of pyrolyzed carbon to coastal systems and the open ocean. Wildfire associated carbon discharged from other high yield fluvial systems, when considered collectively, may be a significant source of lignin, pyrolytic PAHs, and other pyrogenic compounds to the ocean. Extrapolating these methods over geologic time may offer useful historical information about carbon sequestration and burial in coastal sediments and affect coastal carbon budgets.

Mixed infections can significantly contribute to the uncertainty in host-pathogen dynamics with direct impacts on virulence. Toward further understanding of how host-parasite and parasite-parasite relationships may impact virulence, this study characterizes within-host diversity of malaria parasite populations based on genetic analysis of the trap (thrombospondin-related anonymous protein) gene in isolates originating from Hawaii, Maui and Kauai Islands. Methods: A total of 397 clones were produced by nested PCR amplification and cloning of a 1664 bp fragment of the trap gene from two malarial isolates, K1 (Kauai) and KV115 (Hawaii) that have been used for experimental studies, and from additional isolates from wild birds on Kauai, Maui and Hawaii Islands. Diversity of clones was evaluated initially by RFLP-based screening, followed by complete sequencing of 33 selected clones. Results: RFLP analysis of trap revealed a minimum of 28 distinct RFLP haplotypes among the 397 clones from 18 birds. Multiple trap haplotypes were detected in every bird evaluated, with an average of 5.9 haplotypes per bird. Overall diversity did not differ between the experimental isolates, however, a greater number of unique haplotypes were detected in K1 than in KV115. We detected high levels of clonal diversity with clear delineation between isolates K1 and KV115 in a haplotype network. The patterns of within-host haplotype clustering are consistent with the possibility of a clonal genetic structure and rapid within-host mutation after infection. Conclusion: Avian malaria (P. relictum) and Avipoxvirus are the significant infectious diseases currently affecting the native Hawaiian avifauna. This study shows that clonal diversity of Hawaiian isolates of P. relictum is much higher than previously recognized. Mixed infections can significantly contribute to the uncertainty in host-pathogen dynamics with direct implications for host demographics, disease management strategies, and evolution of virulence. The results of this study indicate a widespread presence of multiple-genotype malaria infections with high clonal diversity in native birds of Hawaii, which when coupled with concurrent infection with Avipoxvirus, may significantly influence evolution of virulence. ?? 2008 Jarvi et al; licensee BioMed Central Ltd.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Biology Direct","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1186/1745-6150-3-25","issn":"17456150","usgsCitation":"Jarvi, S., Farias, M., and Atkinson, C., 2008, Genetic characterization of Hawaiian isolates of Plasmodium relictum reveals mixed-genotype infections: Biology Direct, v. 3, https://doi.org/10.1186/1745-6150-3-25.","costCenters":[],"links":[{"id":476550,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1186/1745-6150-3-25","text":"Publisher Index Page"},{"id":18863,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1186/1745-6150-3-25"},{"id":203282,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b24e4b07f02db6aeb71","contributors":{"authors":[{"text":"Jarvi, S.I.","contributorId":60341,"corporation":false,"usgs":true,"family":"Jarvi","given":"S.I.","affiliations":[],"preferred":false,"id":345769,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Farias, M.E.M.","contributorId":68439,"corporation":false,"usgs":true,"family":"Farias","given":"M.E.M.","email":"","affiliations":[],"preferred":false,"id":345770,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Atkinson, C.

D. (1996) Transition metal catalysis in the generation of natural gas. Org. Geochem.24, 977–984). This controversial hypothesis may have important implications concerning gas generation in unconventional shale-gas accumulations. Although experiments have been conducted to test the metal-catalysis hypothesis, their approach and results remain equivocal in evaluating natural assemblages of transition metals and organic matter in shale. The Permian Kupferschiefer of Poland offers an excellent opportunity to test the hypothesis with immature to marginally mature shale rich in both transition metals and organic matter. Twelve subsurface samples containing similar Type-II kerogen with different amounts and types of transition metals were subjected to hydrous pyrolysis at 330° and 355 °C for 72 h. The gases generated in these experiments were quantitatively collected and analyzed for molecular composition and stable isotopes. Expelled immiscible oils, reacted waters, and spent rock were also quantitatively collected. The results show that transition metals have no effect on methane yields or enrichment. δ<sup>13</sup>C values of generated methane, ethane, propane and butanes show no systematic changes with increasing transition metals. The potential for transition metals to enhance gas generation and oil cracking was examined by looking at the ratio of the generated hydrocarbon gases to generated expelled immiscible oil (i.e., GOR), which showed no systematic change with increasing transition metals. Assuming maximum yields at 355 °C for 72 h and first-order reaction rates, pseudo-rate constants for methane generation at 330 °C were calculated. These rate constants showed no increase with increasing transition metals. The lack of a significant catalytic effect of transition metals on the extent, composition, and timing of natural gas generation in these experiments is attributed to the metals not occurring in the proper form or the poisoning of potential catalytic microcosms by polar-rich bitumen, which impregnates the rock matrix during the early stages of petroleum formation.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geochimica et Cosmochimica Acta","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.gca.2008.06.003","issn":"00167037","usgsCitation":"Lewan, M.D., Kotarba, M., Wieclaw, D., and Piestrzynski, A., 2008, Evaluating transition-metal catalysis in gas generation from the Permian Kupferschiefer by hydrous pyrolysis: Geochimica et Cosmochimica Acta, v. 72, no. 16, p. 4069-4093, https://doi.org/10.1016/j.gca.2008.06.003.","productDescription":"25 p.","startPage":"4069","endPage":"4093","costCenters":[],"links":[{"id":203383,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":18740,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.gca.2008.06.003"}],"country":"Poland","otherGeospatial":"Permian Kupferschiefer","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 14.1,49.0 ], [ 14.1,54.8 ], [ 24.1,54.8 ], [ 24.1,49.0 ], [ 14.1,49.0 ] ] ] } } ] }","volume":"72","issue":"16","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a50e4b07f02db629670","contributors":{"authors":[{"text":"Lewan, M.

Results show that naturally-occurring microorganisms associated with the coals produced substantial quantities of methane, although the factors influencing this process were variable among different samples tested. Methanogenic microbes in two coals from the Powder River Basin, Wyoming, USA, produced 140.5-374.6 mL CH<sub>4</sub>/kg ((4.5-12.0 standard cubic feet (scf)/ton) in response to an amendment of H<sub>2</sub>/CO<sub>2</sub>. The addition of high concentrations (5-10 mM) of acetate did not support substantive methane production under the laboratory conditions. However, acetate accumulated in control incubations where methanogenesis was inhibited, indicating that acetate was produced and consumed during the course of methane production. Acetogenesis from H<sub>2</sub>/CO<sub>2</sub> was evident in these incubations and may serve as a competing metabolic mode influencing the cumulative amount of methane produced in coal. Two low-rank (lignite A) coals from Fort Yukon, Alaska, USA, demonstrated a comparable level of methane production (131.1-284.0 mL CH4/kg (4.2-9.1 scf/ton)) in the presence of an inorganic nutrient amendment, indicating that the source of energy and organic carbon was derived from the coal. The concentration of chloroform-extractable organic matter varied by almost three orders of magnitude among all the coals tested, and appeared to be related to methane production potential. These results indicate that substrate availability within the coal matrix and competition between different groups of microorganisms are two factors that may exert a profound influence on methanogenesis in subsurface coal beds.","language":"English","publisher":"Elsevier","doi":"10.1016/j.coal.2008.05.019","issn":"01665162","usgsCitation":"Harris, S.H., Smith, R.L., and Barker, C., 2008, Microbial and chemical factors influencing methane production in laboratory incubations of low-rank subsurface coals: International Journal of Coal Geology, v. 76, no. 1-2, p. 46-51, https://doi.org/10.1016/j.coal.2008.05.019.","productDescription":"6 p.","startPage":"46","endPage":"51","costCenters":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":18635,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.coal.2008.05.019"},{"id":203679,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"76","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a57e4b07f02db62df1c","contributors":{"authors":[{"text":"Harris, Stephen H.","contributorId":20055,"corporation":false,"usgs":true,"family":"Harris","given":"Stephen","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":344723,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Smith, Richard L. 0000-0002-3829-0125 rlsmith@usgs.gov","orcid":"https://orcid.org/0000-0002-3829-0125","contributorId":1592,"corporation":false,"usgs":true,"family":"Smith","given":"Richard","email":"rlsmith@usgs.gov","middleInitial":"L.","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},{"id":36183,"text":"Hydro-Ecological Interactions Branch","active":true,"usgs":true},{"id":38175,"text":"Toxics Substances Hydrology Program","active":true,"usgs":true}],"preferred":true,"id":344722,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Barker, Charles E.","contributorId":93070,"corporation":false,"usgs":true,"family":"Barker","given":"Charles E.","affiliations":[],"preferred":false,"id":344724,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

LABs supplanted TABs in the mid-1960s because of improved biodegradability of their sulfonated analogs. Use of LCABs for molecular stratigraphy depends on their preservation in sediments over decadal time scales. Most laboratory and field studies suggest that LABs degrade rapidly under aerobic conditions but are resistant to degradation when oxygen is absent. However, recent work indicates that LABs may not be as persistent under reducing conditions as previously thought. To assess the potential for degradation of LCABs in reducing sediments, box cores collected in 1992 and 2003 near a submarine wastewater outfall system were analyzed using gas chromatography/mass spectrometry. The TABs were effectively preserved; differences between whole-core inventories were within analytical error.

The recovered sequences associated with coal thus appear to be both phylogenetically and functionally distinct from those that are more closely associated with the produced water. To be able to relate such recovered sequences to organisms that might be present and possibly active in these environments, it is suggested that direct observation, followed by isolation and single cell-based physiological/molecular analyses, be used to characterize methanogenic consortia possibly associated with coals and/or produced waters. It is also important to characterize the microenvironment where these microbes might be found, in both ecological and geological contexts, to be able to develop effective, ecologically relevant coalbed methane regeneration processes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"International Journal of Coal Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.coal.2008.05.023","issn":"01665162","usgsCitation":"Klein, D.A., Flores, R.M., Venot, C., Gabbert, K., Schmidt, R., Stricker, G.D., Pruden, A., and Mandernack, K., 2008, Molecular sequences derived from Paleocene Fort Union Formation coals vs. associated produced waters: Implications for CBM regeneration: International Journal of Coal Geology, v. 76, no. 1-2, p. 3-13, https://doi.org/10.1016/j.coal.2008.05.023.","productDescription":"11 p.","startPage":"3","endPage":"13","numberOfPages":"11","additionalOnlineFiles":"N","costCenters":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":18634,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.coal.2008.05.023"},{"id":203519,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"76","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b23e4b07f02db6ae08e","contributors":{"authors":[{"text":"Klein, Donald A.","contributorId":53076,"corporation":false,"usgs":true,"family":"Klein","given":"Donald","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":344716,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Flores, Romeo M. rflores@usgs.gov","contributorId":71984,"corporation":false,"usgs":true,"family":"Flores","given":"Romeo","email":"rflores@usgs.gov","middleInitial":"M.","affiliations":[{"id":165,"text":"Central Energy Resources Team","active":false,"usgs":true}],"preferred":false,"id":344718,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Venot, Christophe","contributorId":53506,"corporation":false,"usgs":true,"family":"Venot","given":"Christophe","email":"","affiliations":[],"preferred":false,"id":344717,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Gabbert, Kendra","contributorId":20877,"corporation":false,"usgs":true,"family":"Gabbert","given":"Kendra","email":"","affiliations":[],"preferred":false,"id":344714,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Schmidt, Raleigh","contributorId":85306,"corporation":false,"usgs":true,"family":"Schmidt","given":"Raleigh","email":"","affiliations":[],"preferred":false,"id":344719,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Stricker, Gary D. gstricker@usgs.gov","contributorId":87163,"corporation":false,"usgs":true,"family":"Stricker","given":"Gary","email":"gstricker@usgs.gov","middleInitial":"D.","affiliations":[{"id":165,"text":"Central Energy Resources Team","active":false,"usgs":true}],"preferred":false,"id":344720,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Pruden, Amy","contributorId":103398,"corporation":false,"usgs":true,"family":"Pruden","given":"Amy","email":"","affiliations":[],"preferred":false,"id":344721,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Mandernack, Kevin","contributorId":37458,"corporation":false,"usgs":true,"family":"Mandernack","given":"Kevin","affiliations":[],"preferred":false,"id":344715,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

We conducted a stratified multi-stage sample survey on state and federal lands in the MAV of Arkansas, Louisiana, Mississippi, and Missouri during autumns 2002?2004 to generate a contemporary estimate of combined dry mass of seeds and tubers (herein seed abundance) in managed moist-soil units for use by the Lower Mississippi Valley Joint Venture (LMVJV) of the North American Waterfowl Management Plan.  We also examined variation in mean seed abundance among moist-soil units in 2003 and 2004 in relation to management intensity (active or passive), soil pH and nutrient levels, proportional occurrence of plant life-forms (e.g., grass, flatsedge, and forb; vine; woody plants), and unit area.  Estimates of mean seed abundance were similar in 2002 (X over bar = 537.1 kg/ha, SE = 100.1) and 2004 (X over bar = 555.2 kg/ha, SE = 105.2) but 35?40% less in 2003 (X over bar = 396.8 kg/ha, SE = 116.1).  Averaged over years, seed abundance was 496.3 kg/ha (SE = 62.0; CV = 12.5%).  Multiple regression analysis indicated seed abundance varied among moist-soil units inversely with proportional occurrence of woody vegetation and unit area and was greater in actively than passively managed units (R2adj = 0.37). Species of early succession grasses occurred more frequently in actively than passively managed units (P < 0.09), whereas mid- and late-succession plants occurred more often in passively managed units (P < 0.02). We recommend the LMVJV consider 556 kg/ha as a measure of seed abundance for use in estimating carrying capacity in managed moist-soil units on public lands in the MAV. We recommend active management of moist-soil units to achieve maximum potential seed production and further research to determine recovery rates of seeds of various sizes from core samples and the relationship between seed abundance and unit area.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"6916_Kross.pdf","usgsCitation":"Kross, J., Kaminski, R., Reinecke, K.J., Penny, E., and Pearse, A., 2008, Moist-soil seed abundance in managed wetlands in the Mississippi Alluvial Valley: Journal of Wildlife Management, v. 72, no. 3, p. 707-714.","productDescription":"707-714","startPage":"707","endPage":"714","numberOfPages":"8","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":201501,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"72","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b04e4b07f02db69927f","contributors":{"authors":[{"text":"Kross, J.","contributorId":57189,"corporation":false,"usgs":true,"family":"Kross","given":"J.","email":"","affiliations":[],"preferred":false,"id":342934,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kaminski, R.M.","contributorId":53330,"corporation":false,"usgs":true,"family":"Kaminski","given":"R.M.","email":"","affiliations":[],"preferred":false,"id":342931,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Reinecke, K.

This study demonstrates that asking visitors about recreation setting attributes uni-dimensionally, a common approach, can yield less informative responses.  Analyses that considered direct tradeoffs revealed more divergent opinions on acceptability for setting attributes than a unidimensional approach.  Findings revealed that visitors to an accessible and popular attraction feature supported trail development options to protect resource conditions with unrestricted visitor access.

We apply the model to two data sets: (1) previously published data for a species of duck, Anas platyrhynchos, and (2) data for a stream fish species, Etheostoma scotti.  We show that in these cases, an incomplete-detection zero-inflated modeling approach yields a superior fit to the data than other models.  We propose that zero-inflated abundance models accounting for incomplete detection be considered when replicate count data are available.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"7009_Wenger.pdf","usgsCitation":"Wenger, S., and Freeman, M.C., 2008, Estimating species occurrence, abundance, and detection probability using zero-inflated distributions: Ecology, v. 89, no. 10, p. 2953-2959.","productDescription":"2953-2959","startPage":"2953","endPage":"2959","numberOfPages":"7","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202631,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":16963,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://www.esajournals.org/doi/abs/10.1890/07-1127.1","linkFileType":{"id":5,"text":"html"}}],"volume":"89","issue":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ce4b07f02db5fc84f","contributors":{"authors":[{"text":"Wenger, S.J.","contributorId":51883,"corporation":false,"usgs":true,"family":"Wenger","given":"S.J.","email":"","affiliations":[],"preferred":false,"id":343134,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Freeman, Mary C. 0000-0001-7615-6923","orcid":"https://orcid.org/0000-0001-7615-6923","contributorId":99659,"corporation":false,"usgs":true,"family":"Freeman","given":"Mary","email":"","middleInitial":"C.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":343135,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Such interactions frequently include wildlife feeding, resulting in food-conditioned behaviors that may cause harm to both wildlife and visitors.  This study developed and applied efficient protocols for simultaneously evaluating wildlife feeding-related behaviors of visitors and related foraging behaviors of chipmunks along a trail in Zion National Park. Unobtrusive observation protocols permitted an evaluation of educational messages delivered, and documentation of wildlife success in obtaining human food and the strength of their food attraction behavior.  Significant improvements were documented for some targeted visitor behaviors and human food available to chipmunks, with minor differences between treatments.  Replication of these protocols as part of a long-term monitoring program can help protected area managers evaluate and improve the efficacy of their interventions and monitor the strength of food attraction behavior in wildlife.","language":"English","publisher":"Taylor & Francis","doi":"10.1080/10871200802270158","usgsCitation":"Marion, J.L., Dvorak, R.G., and Manning, R.E., 2008, Wildlife feeding in parks: methods for monitoring the effectiveness of educational interventions and wildlife food attraction behaviors: Human Dimensions of Wildlife, v. 13, no. 6, p. 429-442, https://doi.org/10.1080/10871200802270158.","productDescription":"14 p.","startPage":"429","endPage":"442","numberOfPages":"14","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":201794,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"13","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49e1e4b07f02db5e4871","contributors":{"authors":[{"text":"Marion, Jeffrey L.","contributorId":56322,"corporation":false,"usgs":true,"family":"Marion","given":"Jeffrey","email":"","middleInitial":"L.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":343191,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dvorak, Robert G.","contributorId":45037,"corporation":false,"usgs":true,"family":"Dvorak","given":"Robert","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":343193,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Manning, Robert E.","contributorId":37463,"corporation":false,"usgs":true,"family":"Manning","given":"Robert","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":343192,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Seeds of both species were either scarified, to represent seed condition after dispersal by terrestrial birds, or left intact, to represent seed condition after dispersal by arboreal birds.  Seeds were distributed along forest transects, and germination, seedling development and mortality were monitored to determine the successes of the two groups at producing seedlings.  Scarified seeds germinated with the early rains of the dry-to-wet-season transition, when erratic rainfall was interspersed with long dry spells.  Intact seeds germinated 30 d later when the rain was more plentiful and regular.  Intact seeds of O. macrocalyx gave rise to significantly more seedlings (41.1% vs. 25.5%) than did scarified seeds, in part, because significantly more seedlings from scarified seeds (n = 20) than from intact seeds (n = 3) died from desiccation when their radicles failed to enter the dry ground present during the dry-to-wet-season transition.  Also, seedlings from scarified seeds were neither larger nor more robust than those from intact seeds despite their longer growing period.  Results are consistent with the hypothesis that dispersal effectiveness of arboreal birds, at least for O. macrocalyx, is greater than that of terrestrial birds.  Screen-house experiments in which seedlings developed under different watering regimes supported this result.  Numbers of seedlings developing from intact and scarified seeds of O. bopiensis did not differ significantly.","language":"English","publisher":"Cambridge University Press","doi":"10.1017/S0266467408005439","usgsCitation":"Foster, M.S., 2008, Potential effects of arboreal and terrestrial avian dispersers on seed dormancy, seed germination and seedling establishment in Ormosia (Papilionoideae) species in Peru: Journal of Tropical Ecology, v. 24, no. 6, p. 619-627, https://doi.org/10.1017/S0266467408005439.","productDescription":"9 p.","startPage":"619","endPage":"627","numberOfPages":"9","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":197810,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"24","issue":"6","noUsgsAuthors":false,"publicationDate":"2008-11-01","publicationStatus":"PW","scienceBaseUri":"4f4e4ad5e4b07f02db6838eb","contributors":{"authors":[{"text":"Foster, Mercedes S.","contributorId":72088,"corporation":false,"usgs":true,"family":"Foster","given":"Mercedes","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":343188,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
