Detection can be hindered by various factors such as cryptic behavior, color patterns, or observer experience. These factors complicate the estimation of state variables of interest (e.g., abundance, occupancy, species richness) as well as the vital rates that induce changes in these state variables (e.g., survival probabilities for abundance; extinction probabilities for occupancy). Although ad hoc methods (e.g., counts uncorrected for detection, return rates) typically perform poorly in the face of no detection, they continue to be used extensively in various fields, including herpetology. However, formal approaches that estimate and account for the probability of detection, such as capture-mark-recapture (CMR) methods and distance sampling, are available. In this paper, we present classical approaches and recent advances in methods accounting for detectability that are particularly pertinent for herpetological data sets. Through examples, we illustrate the use of several methods, discuss their performance compared to that of ad hoc methods, and we suggest available software to perform these analyses. The methods we discuss control for imperfect detection and reduce bias in estimates of demographic parameters such as population size, survival, or, at other levels of biological organization, species occurrence. Among these methods, recently developed approaches that no longer require marked or resighted individuals should be particularly of interest to field herpetologists. We hope that our effort will encourage practitioners to implement some of the estimation methods presented herein instead of relying on ad hoc methods that make more limiting assumptions.</p>","language":"English","publisher":"The Society for the Study of Amphibians and Reptiles","doi":"10.1670/07-061.1","usgsCitation":"Mazerolle, M.J., Bailey, L., Kendall, W.L., Royle, J., Converse, S.J., and Nichols, J., 2007, Making great leaps forward: Accounting for detectability in herpetological field studies: Journal of Herpetology, v. 41, no. 4, p. 672-689, https://doi.org/10.1670/07-061.1.","productDescription":"18 p.","startPage":"672","endPage":"689","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202630,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"41","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a81e4b07f02db649f51","contributors":{"authors":[{"text":"Mazerolle, Marc J.","contributorId":173729,"corporation":false,"usgs":false,"family":"Mazerolle","given":"Marc","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":342861,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bailey, Larissa L.","contributorId":93183,"corporation":false,"usgs":true,"family":"Bailey","given":"Larissa L.","affiliations":[],"preferred":false,"id":342865,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kendall, William L. wkendall@usgs.gov","contributorId":406,"corporation":false,"usgs":true,"family":"Kendall","given":"William","email":"wkendall@usgs.gov","middleInitial":"L.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":342863,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Royle, J.

For chemicals in sediment, the term contaminated is defined as having concentrations above background and significant human health or ecological risk levels.  For biological parameters, a site could be considered contaminated if levels of the parameter are either more or less than the background level, depending on the specific parameter.  Biological parameters can include tissue chemical concentrations in ecological receptors, bioassay responses, bioaccumulation levels, and benthic community metrics.  Chemical parameters can include sediment concentrations of a variety of potentially toxic chemicals.  Indirectly, contaminated harbor sediment can impact shellfish, fish, birds, and marine mammals, and human populations.  This paper summarizes the methods used to define background levels for chemical and biological parameters from a survey of ecological risk investigations of marine harbor sediment at California Navy bases.  Background levels for regional biological indices used to quantify ecological risks for benthic communities are also described.  Generally, background stations are positioned in relatively clean areas exhibiting the same physical and general chemical characteristics as nearby areas with contaminated harbor sediment.  The number of background stations and the number of sample replicates per background station depend on the statistical design of the sediment ecological risk investigation, developed through the data quality objective (DQO) process.  Biological data from the background stations can be compared to data from a contaminated site by using minimum or maximum background levels or comparative statistics.  In Navy ecological risk assessments (ERA's), calculated background levels and appropriate ecological risk screening criteria are used to identify sampling stations and sites with contaminated sediments.","language":"English","publisher":"Taylor & Francis Online","doi":"10.1080/15320380701490150","usgsCitation":"Leadon, C., McDonnell, T., Lear, J., and Barclift, D., 2007, Calculating background levels for ecological risk parameters in toxic harbor sediment: Soil and Sediment Contamination, v. 16, no. 5, p. 433-450, https://doi.org/10.1080/15320380701490150.","productDescription":"18 p.","startPage":"433","endPage":"450","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":201532,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -124.21142578125,\n              42.01665183556825\n            ],\n            [\n              -124.47509765625,\n              40.49709237269567\n            ],\n            [\n              -123.79394531249999,\n              38.92522904714054\n            ],\n            [\n              -122.49755859375,\n              37.10776507118514\n            ],\n            [\n              -120.4541015625,\n              34.470335121217474\n            ],\n            [\n              -118.32275390624999,\n              33.779147331286474\n            ],\n            [\n              -117.24609374999999,\n              32.58384932565662\n            ],\n            [\n              -114.6533203125,\n              32.76880048488168\n            ],\n            [\n              -114.5654296875,\n              32.93492866908233\n            ],\n            [\n              -114.697265625,\n              33.15594830078649\n            ],\n            [\n              -114.521484375,\n              33.97980872872457\n            ],\n            [\n              -114.08203125,\n              34.252676117101515\n            ],\n            [\n              -114.43359375,\n              34.813803317113155\n            ],\n            [\n              -120.05859375,\n              39.07890809706475\n            ],\n            [\n              -119.99267578124999,\n              42.00032514831621\n            ],\n            [\n              -124.21142578125,\n              42.01665183556825\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"16","issue":"5","noUsgsAuthors":false,"publicationDate":"2007-08-14","publicationStatus":"PW","scienceBaseUri":"4f4e48cee4b07f02db545686","contributors":{"authors":[{"text":"Leadon, C.J.","contributorId":10522,"corporation":false,"usgs":true,"family":"Leadon","given":"C.J.","email":"","affiliations":[],"preferred":false,"id":342758,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McDonnell, T.R.","contributorId":7396,"corporation":false,"usgs":true,"family":"McDonnell","given":"T.R.","email":"","affiliations":[],"preferred":false,"id":342756,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lear, J.","contributorId":82426,"corporation":false,"usgs":true,"family":"Lear","given":"J.","email":"","affiliations":[],"preferred":false,"id":342759,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Barclift, D.","contributorId":8968,"corporation":false,"usgs":true,"family":"Barclift","given":"D.","email":"","affiliations":[],"preferred":false,"id":342757,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The most parsimonious model overall contained an independent time trend for survival of each age, morph, and lab-treatment group. For snakes of the first two age groups (ages 1 yr and 2–4 yr), survival tended to decline over the years for both morphs, while for adult snakes (5 yr and older), survival was constant or even slightly increased.

Within the West Gulf Coastal Plain Bird Conservation Region in the south-central United States, populations of this quail species have declined 6.8% annually.  These declines sparked calls for land use change and prompted implementation of various conservation practices.  However, to effectively reverse these declines and restore northern bobwhite to their former population levels, habitat conservation and management efforts must target establishment and maintenance of sustainable populations.  To provide guidance for conservation and restoration of habitat capable of supporting sustainable northern bobwhite populations in the West Gulf Coastal Plain, we modeled their spatial distribution using landscape characteristics derived from 1992 National Land Cover Data and bird detections, from 1990 to 1994, along 10-stop Breeding Bird Survey route segments.  Four landscape metrics influenced detections of northern bobwhite: detections were greater in areas with more grassland and increased aggregation of agricultural lands, but detections were reduced in areas with increased density of land cover edge and grassland edge.  Using these landscape metrics, we projected the abundance and spatial distribution of northern bobwhite populations across the entire West Gulf Coastal Plain.  Predicted populations closely approximated abundance estimates from a different cadre of concurrently collected data but model predictions did not accurately reflect bobwhite detections along species-specific call-count routes in Arkansas and Louisiana.  Using similar methods, we also projected northern bobwhite population distribution circa 1980 based on Land Use Land Cover data and bird survey data from 1976 to 1984.  We compared our 1980 spatial projections with our spatial estimate of 1992 populations to identify areas of population change.

Industrial longline fishing has been suspected to impact upon black-footed albatross populations <i>Phoebastria nigripes</i> by increasing mortality, but no precise estimates of bycatch mortality are available to ascertain this statement. We present a general framework for quantifying the relationship between albatross population and longline fishing in absence of reliable estimates of bycatch rate. 2. We analysed capture-recapture data of a population of black-footed albatross to obtain estimates of survival probability for this population using several alternative models to adequately take into account heterogeneity in the recapture process. Instead of trying to estimate the number of birds killed by using various extrapolations and unchecked assumptions, we investigate the potential relationship between annual adult survival and several measures of fishing effort. Although we considered a large number of covariates, we used principal component analysis to generate a few uncorrelated synthetic variables from the set and thus we maintained both power and robustness. 3. The average survival for 1997-2002 was 92%, a low value compared to estimates available for other albatross species. We found that one of the synthetic variables used to summarize industrial longline fishing significantly explained more than 40% of the variation in adult survival over 11 years, suggesting an impact by longline fishing on albatross' survival. 4. Our analysis provides some evidence of non-linear variation in survival with fishing effort. This could indicate that below a certain level of fishing effort, deaths due to incidental catch can be partially or totally compensated for by a decrease in natural mortality. Another possible explanation is the existence of a strong interspecific competition for accessing the baits, reducing the risk of being accidentally hooked. 5. <i>Synthesis and applications</i>. The suspicion of a significant impact of longline fishing on the black-footed albatross population was supported by the combination of a low estimate of adult survival for the study period, and a significant relationship between adult survival and a synthetic measure of fishing effort. This study highlights the sensitivity of the black-footed albatross to commercial longline fishing, and should exhort fishery management authorities to find adequate seabirds avoidance methods and to encourage their employment.</p>","language":"English","publisher":"Wiley Online","doi":"10.1111/j.1365-2664.2007.01346.x","usgsCitation":"Veran, S., Gimenez, O., Flint, E., Kendall, W., Doherty, P., and Lebreton, J., 2007, Quantifying the impact of longline fisheries on adult survival in the black-footed albatross: Journal of Applied Ecology, v. 44, no. 5, p. 942-952, https://doi.org/10.1111/j.1365-2664.2007.01346.x.","productDescription":"11 p.","startPage":"942","endPage":"952","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":477002,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/j.1365-2664.2007.01346.x","text":"Publisher Index Page"},{"id":201916,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"44","issue":"5","noUsgsAuthors":false,"publicationDate":"2007-07-23","publicationStatus":"PW","scienceBaseUri":"4f4e4b28e4b07f02db6b12d8","contributors":{"authors":[{"text":"Veran, S.","contributorId":87259,"corporation":false,"usgs":true,"family":"Veran","given":"S.","affiliations":[],"preferred":false,"id":342720,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gimenez, O.","contributorId":60748,"corporation":false,"usgs":true,"family":"Gimenez","given":"O.","email":"","affiliations":[],"preferred":false,"id":342718,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Flint, E.","contributorId":8969,"corporation":false,"usgs":true,"family":"Flint","given":"E.","email":"","affiliations":[],"preferred":false,"id":342716,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kendall, W.

It has been increasingly appreciated that these parameters must be estimated separately from detection probability to avoid the biases induced by nondetection error.  Hence, there is now considerable theoretical and practical interest in dynamic occupancy models that contain explicit representations of metapopulation dynamics such as extinction, colonization, and turnover as well as growth rates.  We describe a hierarchical parameterization of these models that is analogous to the state-space formulation of models in time series, where the model is represented by two components, one for the partially observable occupancy process and another for the observations conditional on that process.  This parameterization naturally allows estimation of all parameters of the conventional approach to occupancy models, but in addition, yields great flexibility and extensibility, e.g., to modeling heterogeneity or latent structure in model parameters.  We also highlight the important distinction between population and finite sample inference; the latter yields much more precise estimates for the particular sample at hand.  Finite sample estimates can easily be obtained using the state-space representation of the model but are difficult to obtain under the conventional approach of likelihood-based estimation.  We use R and Win BUGS to apply the model to two examples.  In a standard analysis for the European Crossbill in a large Swiss monitoring program, we fit a model with year-specific parameters.  Estimates of the dynamic parameters varied greatly among years, highlighting the irruptive population dynamics of that species. In the second example, we analyze route occupancy of Cerulean Warblers in the North American Breeding Bird Survey (BBS) using a model allowing for site-specific heterogeneity in model parameters.  The results indicate relatively low turnover and a stable distribution of Cerulean Warblers which is in contrast to analyses of counts of individuals from the same survey that indicate important declines.  This discrepancy illustrates the inertia in occupancy relative to actual abundance.  Furthermore, the model reveals a declining patch survival probability, and increasing turnover, toward the edge of the range of the species, which is consistent with metapopulation perspectives on the genesis of range edges.  Given detection/non-detection data, dynamic occupancy models as described here have considerable potential for the study of distributions and range dynamics.","language":"English","publisher":"Wiley","doi":"10.1890/06-0669.1","usgsCitation":"Royle, J., and Kery, M., 2007, A Bayesian state-space formulation of dynamic occupancy models: Ecology, v. 88, no. 7, p. 1813-1823, https://doi.org/10.1890/06-0669.1.","productDescription":"11 p.","startPage":"1813","endPage":"1823","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":193508,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"88","issue":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b32e4b07f02db6b426f","contributors":{"authors":[{"text":"Royle, J.

One fundamental challenge, then, is that it is generally not feasible to completely enumerate ('census') all individuals present in each sample unit.  This observation bias may consist of several components, including spatial coverage bias (not all individuals in the Population are exposed to sampling) and detection bias (exposed individuals may go undetected).  Thus, observations are biased for the state variable (abundance, occupancy) that is the object of inference.  Moreover, data are often sparse for most observation locations, requiring consideration of methods for spatially aggregating or otherwise combining sparse data among sample units.  The development of methods that unify spatial statistical models with models accommodating non-detection is necessary to resolve important spatial inference problems based on animal survey data.     In this paper, we develop a novel hierarchical spatial model for estimation of abundance and occurrence from survey data wherein detection is imperfect.  Our application is focused on spatial inference problems in the Swiss Survey of Common Breeding Birds.  The observation model for the survey data is specified conditional on the unknown quadrat population size, N(s).  We augment the observation model with a spatial process model for N(s), describing the spatial variation in abundance of the species.  The model includes explicit sources of variation in habitat structure (forest, elevation) and latent variation in the form of a correlated spatial process.  This provides a model-based framework for combining the spatially referenced samples while at the same time yielding a unified treatment of estimation problems involving both abundance and occurrence.     We provide a Bayesian framework for analysis and prediction based on the integrated likelihood, and we use the model to obtain estimates of abundance and occurrence maps for the European Jay (Garrulus glandarius), a widespread, elusive, forest bird.  The naive national abundance estimate ignoring imperfect detection and incomplete quadrat coverage was 77 766 territories.  Accounting for imperfect detection added approximately 18 000 territories, and adjusting for coverage bias added another 131 000 territories to yield a fully corrected estimate of the national total of about 227 000 territories.  This is approximately three times as high as previous estimates that assume every territory is detected in each quadrat.","language":"English","publisher":"Wiley","doi":"10.1890/06-0912.1","usgsCitation":"Royle, J., Kery, M., Gautier, R., and Schmid, H., 2007, Hierarchical spatial models of abundance and occurrence from imperfect survey data: Ecological Monographs, v. 77, no. 3, p. 465-481, https://doi.org/10.1890/06-0912.1.","productDescription":"17 p.","startPage":"465","endPage":"481","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":193371,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"77","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1ae4b07f02db6a8794","contributors":{"authors":[{"text":"Royle, J.

Nevertheless, many monitoring programs do not effectively address primary sources of variability in monitoring data, which ultimately may limit the utility of monitoring in identifying declines and improving management. To illustrate the importance of taking into account detectability and spatial variation, we used a recently proposed estimator of abundance (superpopulation estimator) to estimate population size of and number of young produced by the Snail Kite (Rostrhamus sociabilis plumbeus) in Florida. During the last decade, primary recovery targets set by the U.S. Fish and Wildlife Service for the Snail Kite that were based on deficient monitoring programs (i.e., uncorrected counts) were close to being met (by simply increasing search effort during count surveys). During that same period, the Snail Kite population declined dramatically (by 55% from 1997 to 2005) and the number of young decreased by 70% between 1992-1998 and 1999-2005. Our results provide a strong practical case in favor of the argument that investing a sufficient amount of time and resources into designing and implementing monitoring programs that carefully address detectability and spatial variation is critical for the conservation of endangered species.</p>","language":"English","publisher":"Wiley for Society for Conservation Biology","doi":"10.1111/j.1523-1739.2006.00613.x","usgsCitation":"Martin, J., Kitchens, W., and Hines, J., 2007, Importance of well-designed monitoring programs for the conservation of endangered species: Case study of the Snail Kite: Conservation Biology, v. 21, no. 2, p. 472-481, https://doi.org/10.1111/j.1523-1739.2006.00613.x.","productDescription":"11 p.","startPage":"472","endPage":"481","costCenters":[{"id":274,"text":"Florida Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true},{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202081,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"21","issue":"2","noUsgsAuthors":false,"publicationDate":"2007-01-15","publicationStatus":"PW","scienceBaseUri":"4f4e4a03e4b07f02db5f83e8","contributors":{"authors":[{"text":"Martin, J.","contributorId":18871,"corporation":false,"usgs":true,"family":"Martin","given":"J.","affiliations":[],"preferred":false,"id":342614,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kitchens, W.M.","contributorId":87647,"corporation":false,"usgs":true,"family":"Kitchens","given":"W.M.","affiliations":[],"preferred":false,"id":342616,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hines, J.E. 0000-0001-5478-7230","orcid":"https://orcid.org/0000-0001-5478-7230","contributorId":36885,"corporation":false,"usgs":true,"family":"Hines","given":"J.E.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":342615,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

We used Mahalanobis Distance (MD) analysis to classify the refuge?s wetlands as poor or good waterbird habitat based on five variables: percent emergent vegetation, percent shrub, percent open water, relative richness of vegetative types, and an interspersion juxtaposition index that measures adjacency of vegetation patches.  Mahalanobis Distance is a multivariate statistic that examines whether a particular data point is an outlier or a member of a data cluster while accounting for correlations among inputs.  For each wetland, we used MD analysis to quantify a distance from a reference condition defined a priori by habitat conditions measured in MNWR wetlands used by waterbirds.  Twenty-five wetlands declined in quality between the two periods, whereas 23 wetlands improved.  We identified specific wetland characteristics that may be modified to improve habitat conditions for waterbirds.  The MD analysis seems ideal for instituting an adaptive wetland management approach because metrics can be easily added or removed, ranges of target habitat conditions can be defined by field-collected data, and the analysis can identify priorities for single or multiple management objectives.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wetlands","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"6736_Hierl.pdf","usgsCitation":"Hierl, L., Loftin, C., Longcore, J.R., McAuley, D., and Urban, D., 2007, A multivariate assessment of changes in wetland habitat for waterbirds at Moosehorn National Wildlife Refuge, Maine, USA: Wetlands, v. 27, no. 1, p. 141-152.","productDescription":"141-152","startPage":"141","endPage":"152","numberOfPages":"12","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202080,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":16842,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://www.bioone.org/perlserv/?request=get-abstract&doi=10.1672%2F0277-5212%282007%2927%5B141%3AAMAOCI%5D2.0.CO%3B2","linkFileType":{"id":5,"text":"html"}}],"volume":"27","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b23e4b07f02db6ade4d","contributors":{"authors":[{"text":"Hierl, L.A.","contributorId":46197,"corporation":false,"usgs":true,"family":"Hierl","given":"L.A.","email":"","affiliations":[],"preferred":false,"id":342609,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Loftin, C.S.","contributorId":92771,"corporation":false,"usgs":true,"family":"Loftin","given":"C.S.","email":"","affiliations":[],"preferred":false,"id":342611,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Longcore, J.

Recent conservation management has emphasized the conversion of cultivated farmland and degraded pastures to intact grassland to improve upland nesting habitat.  The consequences of changes in land-use cover that alter watershed processes have not been evaluated relative to their effect on the water budgets and vegetation dynamics of associated wetlands.  We simulated the effect of upland agricultural practices on the water budget and vegetation of a semipermanent prairie wetland by modifying a previously published mathematical model (WETSIM).  Watershed cover/land-use practices were categorized as unmanaged grassland (native grass, smooth brome), managed grassland (moderately heavily grazed, prescribed burned), cultivated crops (row crop, small grain), and alfalfa hayland.  Model simulations showed that differing rates of evapotranspiration and runoff associated with different upland plant-cover categories in the surrounding catchment produced differences in wetland water budgets and linked ecological dynamics.  Wetland water levels were highest and vegetation the most dynamic under the managed-grassland simulations, while water levels were the lowest and vegetation the least dynamic under the unmanaged-grassland simulations.  The modeling results suggest that unmanaged grassland, often planted for waterfowl nesting, may produce the least favorable wetland conditions for birds, especially in drier regions of the Prairie Pothole Region.  These results stand as hypotheses that urgently need to be verified with empirical data.","language":"English","publisher":"Wiley Online","doi":"10.1890/05-1195","usgsCitation":"Voldseth, R., Johnson, W., Gilmanov, T., Guntenspergen, G., and Millett, B., 2007, Model estimation of land-use effects on water levels of northern Prairie wetlands: Ecological Applications, v. 17, no. 2, p. 527-540, https://doi.org/10.1890/05-1195.","productDescription":"14 p.","startPage":"527","endPage":"540","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202770,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Canada, United States","state":"Iowa, Minnesota, Montana, Nebraska, North Dakota, South Dakota","otherGeospatial":"Prairie Pothole Region","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -116.54296874999999,\n              50.233151832472245\n            ],\n            [\n              -108.896484375,\n              47.87214396888731\n            ],\n            [\n              -104.94140625,\n              47.45780853075031\n            ],\n            [\n              -102.39257812499999,\n              47.635783590864854\n            ],\n            [\n              -101.162109375,\n              44.402391829093915\n            ],\n            [\n              -99.40429687500001,\n              42.74701217318067\n            ],\n            [\n              -95.88867187500001,\n              41.57436130598913\n            ],\n            [\n              -95.625,\n              45.89000815866182\n            ],\n            [\n              -95.888671875,\n              49.89463439573421\n            ],\n            [\n              -111.884765625,\n              51.56341232867585\n            ],\n            [\n              -116.54296874999999,\n              50.233151832472245\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"17","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db699b3d","contributors":{"authors":[{"text":"Voldseth, R.A.","contributorId":80778,"corporation":false,"usgs":true,"family":"Voldseth","given":"R.A.","affiliations":[],"preferred":false,"id":342683,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Johnson, W.C.","contributorId":68003,"corporation":false,"usgs":true,"family":"Johnson","given":"W.C.","email":"","affiliations":[],"preferred":false,"id":342681,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gilmanov, T.","contributorId":72892,"corporation":false,"usgs":true,"family":"Gilmanov","given":"T.","email":"","affiliations":[],"preferred":false,"id":342682,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Guntenspergen, G.R. 0000-0002-8593-0244","orcid":"https://orcid.org/0000-0002-8593-0244","contributorId":95424,"corporation":false,"usgs":true,"family":"Guntenspergen","given":"G.R.","affiliations":[],"preferred":false,"id":342684,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Millett, B.V.","contributorId":48274,"corporation":false,"usgs":true,"family":"Millett","given":"B.V.","email":"","affiliations":[],"preferred":false,"id":342680,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Asymptotes deviated slightly (0.3‰ to 0.7‰) from that of captive shorebirds fed a diet of only crab eggs during stopover, thus confirming a strong crab egg-shorebird linkage. The plasma δ</span><sup>15</sup><span>N crab-egg diet asymptote was enriched ca +4.5‰ and therefore readily discriminated from that of either blue mussels&nbsp;</span><i>Mytilus edulis</i><span>&nbsp;or coquina clams&nbsp;</span><i>Donax variabilis</i><span>, the most likely alternative prey of knots in Delaware Bay. Crab eggs were highly palatable to captive knots and turnstones which achieved rates of mass gain (3–11 g/d) comparable to that of free-ranging birds. Peak consumption rates during hyperphagic events were 23,940 and 19,360 eggs/bird/d, respectively. The empirical conversions of eggs consumed to body mass gained (5,017 eggs/g for knots and 4,320 eggs/g for turnstones) indicate the large quantities of crab eggs required for the maintenance of these shorebird populations during stopover.</span></p>","language":"English","publisher":"Wiley Online","doi":"10.1111/j.0908-8857.2007.03898.x","usgsCitation":"Haramis, G., Link, W., Osenton, P., Carter, D.B., Weber, R., Clark, N., Teece, M., and Mizrahi, D., 2007, Stable isotope and pen feeding trial studies confirm the value of horseshoe crab Limulus polyphemus eggs to spring migrant shorebirds in Delaware Bay: Journal of Avian Biology, v. 38, no. 3, p. 367-376, https://doi.org/10.1111/j.0908-8857.2007.03898.x.","productDescription":"10 p.","startPage":"367","endPage":"376","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":203046,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Delaware","otherGeospatial":"Delaware Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -75.399169921875,\n              39.07037913108751\n            ],\n            [\n              -75.2783203125,\n              38.846125291387025\n            ],\n            [\n              -75.11077880859375,\n              38.777640223073355\n            ],\n            [\n              -74.94873046875,\n              38.852542390364235\n            ],\n            [\n              -74.97344970703124,\n              38.98503278695909\n            ],\n            [\n              -74.90478515625,\n              39.091699613104595\n            ],\n            [\n              -74.9212646484375,\n              39.1854331703021\n            ],\n            [\n              -75.39642333984374,\n              39.22799807055236\n            ],\n            [\n              -75.399169921875,\n              39.07037913108751\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"38","issue":"3","noUsgsAuthors":false,"publicationDate":"2007-11-06","publicationStatus":"PW","scienceBaseUri":"4f4e49e1e4b07f02db5e4921","contributors":{"authors":[{"text":"Haramis, G.M.","contributorId":101212,"corporation":false,"usgs":true,"family":"Haramis","given":"G.M.","email":"","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":342679,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Link, W.A. 0000-0002-9913-0256","orcid":"https://orcid.org/0000-0002-9913-0256","contributorId":8815,"corporation":false,"usgs":true,"family":"Link","given":"W.A.","affiliations":[],"preferred":false,"id":342672,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Osenton, P.C.","contributorId":20441,"corporation":false,"usgs":true,"family":"Osenton","given":"P.C.","affiliations":[],"preferred":false,"id":342674,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Carter, Daniel B.","contributorId":18880,"corporation":false,"usgs":true,"family":"Carter","given":"Daniel","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":342673,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Weber, R.G.","contributorId":38686,"corporation":false,"usgs":true,"family":"Weber","given":"R.G.","affiliations":[],"preferred":false,"id":342678,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Clark, N.A.","contributorId":27596,"corporation":false,"usgs":true,"family":"Clark","given":"N.A.","email":"","affiliations":[],"preferred":false,"id":342675,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Teece, M.A.","contributorId":31882,"corporation":false,"usgs":true,"family":"Teece","given":"M.A.","affiliations":[],"preferred":false,"id":342676,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Mizrahi, D.S.","contributorId":34237,"corporation":false,"usgs":true,"family":"Mizrahi","given":"D.S.","email":"","affiliations":[],"preferred":false,"id":342677,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

Typically, researchers have detected <i>B. dendrobatidis</i> only when examining amphibians for causes of mortalities; few data exist on infection rates where mortalities are lacking. During May-September 2000-2002 we obtained amphibian specimens killed by vehicles and others collected at remote off-road sites throughout Maine, USA, and from federal lands in 5 states in the Northeast. We detected infected specimens, mostly green frogs (<i>Rana clamitans</i>), at 5 of 7 national wildlife refuges, a federal waterfowl production area, and Acadia National Park. Seven of 9 species, including all Ranidae species, were infected throughout Maine; rates ranged from 14.6% in American toads (<i>Bufo americanus</i>) to 25.7% in northern leopard frogs (<i>Rana pipiens</i>). We did not detect any infections in 50 eastern gray tree frogs (<i>Hyla versicolor</i>) or 21 spring peepers (<i>Pseudacris crucifer</i>). Species that hibernate in terrestrial habitats seem to have lower rates of infection than species that hibernate in aquatic habitats. Infections peaked in spring and autumn and were associated with air temperatures optimal for <i>B. dendrobatidis</i> growth. The relatively high infection rates among species without documented die-offs suggest that either losses have occurred undetected, that the fungus is endemic and species have attained a level of resistance to infections becoming lethal, or that climatic conditions of the Northeast have a role in preventing infections from being lethal. Data on prevalence and distribution of this chytrid fungus in the Northeast may be useful in modeling its origins and predicting long-term ecosystem effects involving anurans.</p>","language":"English","publisher":"BioOne Complete","doi":"10.2193/2006-345","usgsCitation":"Longcore, J.R., Longcore, J., Pessier, A.P., and Halteman, W., 2007, Chytridiomycosis

The Patuxent Research Refuge initiated such a calling survey in the spring of 1997, which uses volunteers to collect anuran (frog and toad) calling survey data. The primary goal of initiating the calling surveys at the Patuxent Refuge was to obtain baseline information on anuran populations, such as species occurrence, frequency of occurrence, and relative abundance over time. In this paper, we used the calling survey data to develop models for the \"proportion of area occupied\" by individual anuran species, a method in which analysis is focused on the proportion of sites that are occupied by a species, instead of the number of individuals present in the population. This type of analysis is ideal for use in large-scale monitoring programs focused on species that are difficult to count, such as anurans or birds. We considered models for proportion of area occupied that allow for imperfect detection (that is, a species may be present but go undetected during sampling) by incorporating parameters that describe detection probability and the response of detection probability to various environmental and sampling covariates. Our results indicate that anuran populations on the Patuxent Research Refuge have high rates of occupancy compared to areas nearby and that extinction and colonization rates are stable. The potential uses for \"proportion of area occupied\" analyses are far-reaching and will allow for more accurate quantification of data and better-informed management decisions for calling surveys on a larger scale.</p>","language":"English","publisher":"BioOne Complete","doi":"10.1670/0022-1511(2007)41[52:EOTSOA]2.0.CO;2","usgsCitation":"Brander, S., Royle, J., and Eames, M., 2007, Evaluation of

In particular, mark-recapture methodology has shown that incorporating uncertainty in the probability of detecting individuals in populations enables accurate estimation of population-level processes such as survival, reproduction, and dispersal. Recent advances in mark-recapture methodology have included estimating population-level processes for biologically important groups despite the misassignment of individuals to those groups. Examples include estimating rates of apparent survival despite less than perfect accuracy when identifying individuals to gender or breeding state. Here we introduce a method for estimating apparent survival and dispersal in species that co-occur but that are difficult to distinguish.

Habitat loss and fragmentation due to land use changes is thought to be one of the major factors contributing to the decline.  BBS routes, the primary source for monitoring bird population trends, include 50 sampling stops every 0.8 km.  Although data from BBS routes are extrapolated to determine regional trends in bird populations, it is important to understand the effects of habitat changes at the stop-level along BBS routes.  Route-level analysis of habitat changes may mask important changes that are occurring at a smaller scale particularly for the cerulean warbler which displays several micro-scale habitat preferences.  We are examining cerulean warbler habitat and population changes in its core breeding range of the Ohio Hills and Cumberland Plateau physiographic regions.  We quantified land cover changes within 300 m of BBS routes in the core cerulean warbler breeding range of Ohio, West Virginia, and Kentucky by digitizing aerial photographs from two time periods: the 1980s and 2004.  We also quantified land cover changes within 300 m of BBS routes with the National Land Cover Dataset (NLCD) from 1992 and 2001.  The hand-digitized aerial photos will be compared with the NLCD to determine how similar the two methods are in quantifying land cover changes.  We then compared stop-level land cover changes with stop level changes in cerulean warbler detections within the same time periods along the BBS routes.  This will allow for a more detailed analysis of how well habitat changes along BBS routes reflect the changes in cerulean warbler populations.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Proceedings of the Annual Conference of the Southeastern Association of Fish and Wildlife Agencies","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"McElhone, P., Wood, P., and Dawson, D., 2007, Effects of habitat change along Breeding Bird Survey routes in the central Appalachians on Cerulean Warbler population: Proceedings of the Annual Conference of the Southeastern Association of Fish and Wildlife Agencies, v. 61.","productDescription":"131 (abstract)","startPage":"131 (abs)","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":16823,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://24.73.102.130/resource/dynamic/private/PDF/McElhone-131.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":202247,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"61","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a2ce4b07f02db613ad9","contributors":{"authors":[{"text":"McElhone, P.","contributorId":52302,"corporation":false,"usgs":true,"family":"McElhone","given":"P.","email":"","affiliations":[],"preferred":false,"id":343037,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wood, P.W.","contributorId":81608,"corporation":false,"usgs":true,"family":"Wood","given":"P.W.","email":"","affiliations":[],"preferred":false,"id":343039,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Dawson, D.","contributorId":72901,"corporation":false,"usgs":true,"family":"Dawson","given":"D.","email":"","affiliations":[],"preferred":false,"id":343038,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

When selecting variables to monitor, managers first need to carefully consider their objectives, the geographic and temporal scale at which they will operate, and the effort needed to implement the program.  Generally, monitoring can be divided into two categories: index and inferential.  Although index monitoring is usually easier to implement, analysis of index data requires strong assumptions about consistency in detection rates over time and space, and parameters are often biasednot accounting for detectability and spatial variation.  In most cases, individuals are not always available for detection during sampling periods, and the entire area of interest cannot be sampled.  Conversely, inferential monitoring is more rigorous because it is based on nearly unbiased estimators of spatial distribution.  Thus, we recommend that detectability and spatial variation be considered for all monitoring programs that intend to make inferences about the target population or the area of interest.  Application of these techniques is especially important for the monitoring of Threatened and Endangered (T&E) species because it is critical to determine if population size is increasing or decreasing with some level of certainty.  Use of estimation-based methods and probability sampling will reduce many of the biases inherently associated with index data and provide meaningful information with respect to changes that occur in target populations.  We incorporated inferential monitoring into protocols for T&E species spanning a wide range of taxa on the Cherokee National Forest in the Southern Appalachian Mountains.  We review the various approaches employed for different taxa and discuss design issues, sampling strategies, data analysis, and the details of estimating detectability using site occupancy.  These techniques provide a science-based approach for monitoring and can be of value to all resource managers responsible for management of T&E species.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Proceedings of the Annual Conference of the Southeastern Association of Fish and Wildlife Agencies","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Klimstra, J., O'Connell, A., Pistrang, M., Lewis, L., Herrig, J., and Sauer, J., 2007, Design and implementation of estimation-based monitoring programs for flora and fauna: A case study on the Cherokee National Forest: Proceedings of the Annual Conference of the Southeastern Association of Fish and Wildlife Agencies, v. 61.","productDescription":"126 (abstract)","startPage":"126 (abs)","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":16821,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://24.73.102.130/resource/dynamic/private/PDF/Klimstra-126.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":202567,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"61","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aa9e4b07f02db667eb7","contributors":{"authors":[{"text":"Klimstra, J.D.","contributorId":62328,"corporation":false,"usgs":true,"family":"Klimstra","given":"J.D.","email":"","affiliations":[],"preferred":false,"id":343031,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"O'Connell, A.F.

Locations in a wide geographical area with a range of environmental variables were selected for patch-occupancy surveys using elephant dung to assess seasonal presence and absence of elephants.  Patch-occupancy procedures allowed for covariate modelling evaluating hypotheses for both occupancy in relation to human activity and ecological features, and detection probability in relation to vegetation density.  The best fitting models for old and fresh dung data sets indicate that (1) detection probability for elephant dung is negatively related to the relative density of the vegetation, and (2) human activity, such as presence and infrastructure, are more closely associated with elephant distribution patterns than are ecological features, such as the presence of wetlands and preferred fresh fruit.  Our findings emphasize the sensitivity of elephants to human disturbance, in this case infrastructure development associated with gas and oil production.  Patch-occupancy methodology offers a viable alternative to current transect protocols for monitoring programs with multiple covariates.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Biological Conservation","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.biocon.2006.10.028","collaboration":"6651_Buij.pdf","usgsCitation":"Buij, R., McShea, W., Campbell, P., Lee, M., Dallmeier, F., Guimondou, S., Mackaga, L., Guisseougou, N., Mboumba, S., Hines, J., Nichols, J., and Alonso, A., 2007, Patch-occupancy models indicate human activity as major determinant of forest elephant <i>Loxodonta cyclotis</i> seasonal distribution in an industrial corridor in Gabon: Biological Conservation, v. 135, no. 2, p. 189-201, https://doi.org/10.1016/j.biocon.2006.10.028.","productDescription":"13 p.","startPage":"189","endPage":"201","numberOfPages":"13","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":196297,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":292002,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.biocon.2006.10.028"}],"country":"Gabon","volume":"135","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae1e4b07f02db6889c3","contributors":{"authors":[{"text":"Buij, R.","contributorId":44632,"corporation":false,"usgs":true,"family":"Buij","given":"R.","affiliations":[],"preferred":false,"id":342406,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McShea, W.J.","contributorId":46187,"corporation":false,"usgs":true,"family":"McShea","given":"W.J.","affiliations":[],"preferred":false,"id":342407,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Campbell, P.","contributorId":99249,"corporation":false,"usgs":true,"family":"Campbell","given":"P.","email":"","affiliations":[],"preferred":false,"id":342409,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Lee, M.E.","contributorId":26779,"corporation":false,"usgs":true,"family":"Lee","given":"M.E.","email":"","affiliations":[],"preferred":false,"id":342402,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Dallmeier, F.","contributorId":39894,"corporation":false,"usgs":true,"family":"Dallmeier","given":"F.","email":"","affiliations":[],"preferred":false,"id":342405,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Guimondou, S.","contributorId":39087,"corporation":false,"usgs":true,"family":"Guimondou","given":"S.","email":"","affiliations":[],"preferred":false,"id":342404,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Mackaga, L.","contributorId":16534,"corporation":false,"usgs":true,"family":"Mackaga","given":"L.","email":"","affiliations":[],"preferred":false,"id":342401,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Guisseougou, N.","contributorId":107393,"corporation":false,"usgs":true,"family":"Guisseougou","given":"N.","email":"","affiliations":[],"preferred":false,"id":342410,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Mboumba, S.","contributorId":12141,"corporation":false,"usgs":true,"family":"Mboumba","given":"S.","email":"","affiliations":[],"preferred":false,"id":342399,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Hines, J.E. 0000-0001-5478-7230","orcid":"https://orcid.org/0000-0001-5478-7230","contributorId":36885,"corporation":false,"usgs":true,"family":"Hines","given":"J.E.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":342403,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Nichols, J.D. 0000-0002-7631-2890","orcid":"https://orcid.org/0000-0002-7631-2890","contributorId":14332,"corporation":false,"usgs":true,"family":"Nichols","given":"J.D.","affiliations":[],"preferred":false,"id":342400,"contributorType":{"id":1,"text":"Authors"},"rank":11},{"text":"Alonso, A.","contributorId":57561,"corporation":false,"usgs":true,"family":"Alonso","given":"A.","email":"","affiliations":[],"preferred":false,"id":342408,"contributorType":{"id":1,"text":"Authors"},"rank":12}]}}

Despite industry laboratories classifying trenbolone as nonteratogenic, data showed that embryonic exposure to this androgenic chemical altered development of the immune system in Japanese quail.  Trenbolone is lipophilic, persistent, and released into the environment in manure used as soil fertilizer.  This is the first study to date to assess this chemical's immunotoxic effects in an avian species.  A one-time injection of trenbolone into yolks was administered to mimic maternal deposition, and subsequent effects on the development and function of the immune system were determined in chicks and adults.  Development of the bursa of Fabricius, an organ responsible for development of the humoral arm of the immune system, was disrupted, as indicated by lower masse, and smaller and fewer follicles at day 1 of hatch.  Morphological differences in the bursas persisted in adults, although no differences in either two measures of immune function were observed.  Total numbers of circulating leukocytes were reduced and heterophil-lymphocyte ratios were elevated in chicks but not adults.  This study shows that trenbolone acetate is teratogenic and immunotoxic in Japanese quail, and provides evidence that the quail immune system may be fairly resilient to embryonic endocrine-disrupting chemical-induced alterations following no further exposure posthatch.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Toxicology and Environmental Health, Part A","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1080/15287390600755026","collaboration":"6681_Quinn.pdf","usgsCitation":"Quinn, M., McKernan, M., Lavoie, E., and Ottinger, M.A., 2007, Immunotoxicity of trenbolone acetate in Japanese quail: Journal of Toxicology and Environmental Health, Part A, v. 70, no. 1, p. 88-93, https://doi.org/10.1080/15287390600755026.","productDescription":"88-93","startPage":"88","endPage":"93","numberOfPages":"6","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":201497,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":269418,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1080/15287390600755026"}],"volume":"70","issue":"1","noUsgsAuthors":false,"publicationDate":"2007-02-24","publicationStatus":"PW","scienceBaseUri":"4f4e4ae1e4b07f02db6887ba","contributors":{"authors":[{"text":"Quinn, M.J.","contributorId":50990,"corporation":false,"usgs":true,"family":"Quinn","given":"M.J.","affiliations":[],"preferred":false,"id":342497,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McKernan, M.","contributorId":103388,"corporation":false,"usgs":true,"family":"McKernan","given":"M.","email":"","affiliations":[],"preferred":false,"id":342500,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lavoie, E.T.","contributorId":94767,"corporation":false,"usgs":true,"family":"Lavoie","given":"E.T.","email":"","affiliations":[],"preferred":false,"id":342498,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ottinger, M.

Premining streamflow characteristics and streamflow gain-loss variation were determined so that pre- and postmining gain-loss characteristics could be compared. This report describes the methods used in this study and the results of two streamflow-measurement sets collected during low-flow conditions.\r\n\r\nStreamflow gain-loss measurements were collected using rhodamine WT and sodium bromide tracers at four sites spanning the mine-permit area on June 26-28, 2007. Streamflows were estimated and compared between four measurement sites within three stream subreaches of the study reach. Data from two streamflow-gaging stations on Hubbard Creek upstream and downstream from the mine-permit area were evaluated. Streamflows at the stations were continuous, and flow at the upstream station nearly always exceeded the streamflow at the downstream station. Furthermore, streamflow at both stations showed similar diurnal patterns with traveltime offsets.\r\n\r\nOn June 26, streamflow from the gain-loss measurements was greater at site 1 (most upstream site) than at site 4 (most downstream site); on June 27, streamflow was greater at site 4 than at site 2; and on June 27, there was no difference in streamflow between sites 2 and 3. Data from streamflow-gaging stations 09132940 and 09132960 showed diurnal variations and overall decreasing streamflow over time. The data indicate a dynamic system, and streamflow can increase or decrease depending on hydrologic conditions. The streamflow within the study reach was greater than the streamflows at either the upstream or downstream stations.\r\n\r\nA second set of gain-loss measurements was collected at sites 2 and 4 on November 8-9, 2007. On November 8, streamflow was greater at site 4 than at site 2, and on the following day, November 9, streamflow was greater at site 2 than at site 4. Data collection on November 8 occurred while the streamflow was increasing due to contributions from stream ice melting throughout different parts of the basin. Data collection on November 9 occurred earlier in the day with less stream ice melting and more steady-state conditions, so the indication that streamflow decreased between sites 2 and 4 may be more accurate.\r\n\r\nDiurnal variations in streamflow are common at both the upper and the lower streamflow-gaging stations. The upper streamflow-gaging station shows a melt-freeze influence from tributaries to Hubbard Creek during the winter season. Downstream from the study reach, observed diurnal variation is likely due to evapotranspiration associated with dense flood-plain vegetation, which consumes water from the creek during the middle of the day. Varying diurnal patterns in streamflow, combined with possible variations in tributary inflows to Hubbard Creek in the study reach, probably account for the observed variations in streamflow at the tracer measurement sites.\r\n\r\nDuring both sampling periods in June and November 2007, conditions were less than ideal and not steady state. The June 27 sampling indicates that the streamflow was increasing between measurement sites 2 and 4, and the November 9 sampling indicates that the streamflow was decreasing between measurement sites 2 and 4. The data collected during the diurnal and day-to-day variations in streamflow indicated that the streamflow reach is dynamic and can be gaining, losing, or constant. \r\n","language":"ENGLISH","publisher":"U.S. Geological Survey","doi":"10.3133/sir20095271","collaboration":"Prepared in cooperation with Bowie Mining Company","usgsCitation":"Ruddy, B.C., and Williams, C.A., 2007, Evaluation of Streamflow Gain-Loss Characteristics of Hubbard Creek, in the Vicinity of a Mine-Permit Area, Delta County, Colorado, 2007: U.S. Geological Survey Scientific Investigations Report 2009-5271, vi, 19 p. , https://doi.org/10.3133/sir20095271.","productDescription":"vi, 19 p.

From 2001 to 2003 we surveyed for vascular plants and vertebrates (amphibians, reptiles, birds, and mammals) at the district to document the presence of species within its boundaries. Park staff also carried out extensive infrared-triggered camera work for medium and large mammals from 2002-2005 and results from that effort are reported here. Our spatial sampling design for all taxa employed a combination of random and nonrandom survey sites. Survey effort was greatest for medium and large mammals and herpetofauna. Because we used repeatable study designs and standardized field methods, these inventories can serve as the first step in a biological monitoring program for the district. We also provide an overview of previous survey efforts in the district. We use data from our inventory and other surveys to compile species lists and to assess inventory completeness. \r\n\r\nThe survey effort for herpetofauna, birds, and medium and large mammals was the most comprehensive ever undertaken in the district. We recorded a total of 320 plant and vertebrate species, including 21 species not previously found in the district (Table 1). Based on a review of our inventory and past research at the district, there have been a total of 723 species of plants and vertebrates found there. We believe inventories for most taxonomic groups are nearly complete. \r\n\r\nBased on our surveys, we believe the native plant and vertebrate community compositions of the district are relatively intact, though some species loss has occurred and threats are increasing, particularly to herpetofauna and larger mammals. Of particular note is the relatively small number of non-native species and their low abundance in the district, which is in contrast to many nearby natural areas. Rapidly expanding development on the west, north, and east sides of the district is cause for concern that the park continue its commitment to environmental restoration, which is largely responsible for reducing the threats posed by non-native plants. With continued maintenance of natural processes and the ecological structure of the park's biodiversity, the park will become an increasingly important place to both the general public and the scientific community.\r\n\r\nThis report supersedes results reported in Powell et al.
