Officials were concerned that human disturbance may have been contributing to this decline in use. We evaluated effects of vehicular traffic and other road-related disturbance on bighorn use of Sheep Lakes in the summers of 2002 and 2003. We found that the time and number of attempts required by bighorn to reach Sheep Lakes was positively related to the number of vehicles and people present at Sheep Lakes. Further, the number of bighorn individuals and groups attempting to visit Sheep Lakes were negatively affected by disturbance associated with the site. The number of vehicles recorded the hour before bighorn tried to access Sheep Lakes best predicted an animal's failure to cross Fall River Road and reach Sheep Lakes. We conclude that human and road-related disturbance at Sheep Lakes negatively affected bighorn use of the mineral site. Because Sheep Lakes may be important for bighorn sheep, especially for lamb production and survival, the negative influence of disturbance may compromise health and productivity of the Mummy Range bighorn sheep.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2193/2006-486","issn":"0022541X","usgsCitation":"Keller, B., and Bender, L.C., 2007, Bighorn sheep response to road-related disturbances in Rocky Mountain National Park, Colorado: Journal of Wildlife Management, v. 71, no. 7, p. 2329-2337, https://doi.org/10.2193/2006-486.","startPage":"2329","endPage":"2337","costCenters":[],"links":[{"id":203799,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":18960,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2193/2006-486"}],"volume":"71","issue":"7","noUsgsAuthors":false,"publicationDate":"2010-12-13","publicationStatus":"PW","scienceBaseUri":"4f4e4a4ce4b07f02db626256","contributors":{"authors":[{"text":"Keller, B.J.","contributorId":88470,"corporation":false,"usgs":true,"family":"Keller","given":"B.J.","email":"","affiliations":[],"preferred":false,"id":346351,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bender, Louis C.","contributorId":72509,"corporation":false,"usgs":true,"family":"Bender","given":"Louis","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":346350,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

We studied late August-March survival of 163 after-hatch-year (AHY) and 128 hatch-year (HY) female mallards (Anas platyrhynchos) radiotagged in Sacramento Valley (SACV) and 885 AHY female northern pintails (A. acuta) radiotagged throughout the Central Valley of California, USA, relative to flooded habitat (HAB), January abundance of each species (JMAL or JPIN), hunter-days (HDY), and a hunting pressure index (HPI) that combined these variables. From EARLY (1987-1994) to LATE (1998-2000), HAB increased 39%, JPIN increased 45%, JMAL increased 53%, HDY increased 21%, duck-hunting season increased from 59 days to 100 days, and the female daily bag limit doubled to 2 for mallards but remained 1 for pintails. Survival (?? SE) was greater during LATE versus EARLY for pintails radiotagged in each region (SACV: 93.2 ?? 2.1% vs. 87.6 ?? 3.0%; Suisun Marsh: 86.6 ?? 3.2% vs. 77.0 ?? 3.7%; San Joaquin Valley: 86.6 ?? 3.1% vs. 76.9 ?? 4.1%) but not for SACV mallards (AHY: 70.6 ?? 7.2% to 74.4 ?? 7.7% vs. 80.1 ?? 7.2% to 82.8 ?? 5.6%; HY: 48.7 ?? 9.1% [1999-2000 only] vs. 63.5 ?? 8.8% to 67.6 ?? 8.0%). Most pintail (72%) and mallard (91%) deaths were from hunting, and lower HPI and higher JPIN or JMAL were associated with reduced mortality. Increased HAB was associated with reduced winter mortality for pintails but not for SACV mallards. Pintail survival rates that we measured were within the range reported for other North American wintering areas, and during LATE were higher than most, even though our study duration was 68-110 days longer. Winter survival rates of SACV mallards were also within the reported range. However, with higher bag limits and longer seasons, mallard survival during LATE was lower than in most other wintering areas, especially during 1999-2000, when high winds on opening weekend resulted in high hunting mortality. Habitat conservation and favorable agriculture practices helped create a Central Valley wintering environment where natural mortality of mallards and pintails was low and survival varied with hunting mortality. We recommend regulations and habitat management that continue to minimize natural mortality while allowing sustainable harvest at a level that helps maintain strong incentive for management of Central Valley waterfowl habitats, including the large portion that is privately owned.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2193/2005-634","issn":"0022541X","usgsCitation":"Fleskes, J., Yee, J., Yarris, G., Miller, M.R., and Casazza, M.L., 2007, Pintail and mallard survival in California relative to habitat, abundance, and hunting: Journal of Wildlife Management, v. 71, no. 7, p. 2238-2248, https://doi.org/10.2193/2005-634.","startPage":"2238","endPage":"2248","costCenters":[],"links":[{"id":203445,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":18961,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2193/2005-634"}],"volume":"71","issue":"7","noUsgsAuthors":false,"publicationDate":"2010-12-13","publicationStatus":"PW","scienceBaseUri":"4f4e4adae4b07f02db685765","contributors":{"authors":[{"text":"Fleskes, J.

During the summers of 2003-2004, 5 detection teams located 1,565 scats (747 putative black bear, 665 putative fisher, and 153 putative bobcat) at 168 survey sites throughout Vermont, USA. Of 347 scats genetically analyzed for species identification, 179 (51.6%) yielded a positive identification, 131 (37.8%) failed to yield DNA information, and 37 (10.7%) yielded DNA but provided no species confirmation. For 70 survey sites where confirmation of a putative target species' scat was not possible, we assessed the probability that ???1 of the scats collected at the site was deposited by the target species (probability of correct identification; P ID). Based on species confirmations or PID values, we detected bears at 57.1% (96) of sites, fishers at 61.3% (103) of sites, and bobcats at 12.5%o (21) of sites. We estimated that the mean probability of detecting the target species (when present) during a single visit to a site was 0.86 for black bears, 0.95 for fishers, and 0.40 for bobcats. The probability of detecting black bears was largely unaffected by site- or visit-specific covariates, but the probability of detecting fishers varied by detection team. We found little or no effect of topographic ruggedness, vegetation density, or local weather (e.g., temp, humidity) on detection probability for fishers or black bears (data were insufficient for bobcat analyses). Detection dogs were highly effective at locating scats from forest carnivores and provided an efficient and accurate method for collecting detection-nondetection data on multiple species.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2193/2006-230","issn":"0022541X","usgsCitation":"Long, R.A., Donovan, T., MacKay, P., Zielinski, W.J., and Buzas, J.S., 2007, Effectiveness of scat detection dogs for detecting forest carnivores: Journal of Wildlife Management, v. 71, no. 6, p. 2007-2017, https://doi.org/10.2193/2006-230.","startPage":"2007","endPage":"2017","costCenters":[],"links":[{"id":203737,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":18966,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2193/2006-230"}],"volume":"71","issue":"6","noUsgsAuthors":false,"publicationDate":"2010-12-13","publicationStatus":"PW","scienceBaseUri":"4f4e4ae2e4b07f02db688ce8","contributors":{"authors":[{"text":"Long, Robert A.","contributorId":11732,"corporation":false,"usgs":false,"family":"Long","given":"Robert","email":"","middleInitial":"A.","affiliations":[{"id":13253,"text":"University of Vermont","active":true,"usgs":false}],"preferred":false,"id":346372,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Donovan, T.M.","contributorId":91602,"corporation":false,"usgs":true,"family":"Donovan","given":"T.M.","email":"","affiliations":[],"preferred":false,"id":346376,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"MacKay, Paula","contributorId":37042,"corporation":false,"usgs":false,"family":"MacKay","given":"Paula","email":"","affiliations":[{"id":13253,"text":"University of Vermont","active":true,"usgs":false}],"preferred":false,"id":346374,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Zielinski, William J.","contributorId":35440,"corporation":false,"usgs":false,"family":"Zielinski","given":"William","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":346373,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Buzas, Jeffrey S.","contributorId":86080,"corporation":false,"usgs":false,"family":"Buzas","given":"Jeffrey","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":346375,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

We obtained the stomach contents from 206 nonnative red foxes (Vulpes vulpes regalis) collected in the South Bay area and Monterey County during 1995-2001 and from 68 feral cats (Felis silvestris) from the South Bay area during 2001-2002. We determined prey identity, biomass, and frequency, described seasonal diet trends, and derived an Index of Relative Importance. Avian species were the most frequent prey we found in the stomachs of red foxes from South Bay (61%), whereas small rodents were most frequent for red foxes from Monterey County (62%). Small rodents were the most frequent prey we found in feral cats (63%). Carbon and nitrogen isotopic signatures for foxes supported stomach content findings. However, isotope results indicated that cats received a majority of their energy from a source other than rodents and outside the natural system, which differed from the stomach content analysis. We demonstrated the utility of both stable isotope and stomach content analyses to establish a more complete understanding of predators' diets. This information aids natural resource managers in planning and evaluating future predator-removal programs and increases our understanding of the impacts of nonnative foxes and cats on native species.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2193/2005-527","issn":"0022541X","usgsCitation":"Meckstroth, A., Miles, A., and Chandra, S., 2007, Diets of introduced predators using stable isotopes and stomach contents: Journal of Wildlife Management, v. 71, no. 7, p. 2387-2392, https://doi.org/10.2193/2005-527.","startPage":"2387","endPage":"2392","costCenters":[],"links":[{"id":203329,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":18958,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2193/2005-527"}],"volume":"71","issue":"7","noUsgsAuthors":false,"publicationDate":"2010-12-13","publicationStatus":"PW","scienceBaseUri":"4f4e4a9ae4b07f02db65d792","contributors":{"authors":[{"text":"Meckstroth, A.M.","contributorId":50464,"corporation":false,"usgs":true,"family":"Meckstroth","given":"A.M.","email":"","affiliations":[],"preferred":false,"id":346344,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Miles, A.K. 0000-0002-3108-808X","orcid":"https://orcid.org/0000-0002-3108-808X","contributorId":85902,"corporation":false,"usgs":true,"family":"Miles","given":"A.K.","affiliations":[],"preferred":false,"id":346346,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Chandra, S.","contributorId":68867,"corporation":false,"usgs":true,"family":"Chandra","given":"S.","email":"","affiliations":[],"preferred":false,"id":346345,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

To assess habitat, we used locations of 239 elk groups collected from helicopter surveys in the Buffalo National River area of northwestern Arkansas, USA, from 1992 to 2002. We calculated the Mahalanobis distance (<i>D</i><sup>2</sup>) statistic based on the relationship between those elk-group locations and a suite of 9 landscape variables to evaluate winter habitat in Arkansas. We tested model performance in the Buffalo National River area by comparing the <i>D</i><sup>2</sup> values of pixels representing areas with and without elk pellets along 19 fixed-width transects surveyed in March 2002. Pixels with elk scat had lower <i>D</i><sup>2</sup> values than pixels in which we found no pellets (logistic regression: Wald &chi;<sup>2</sup> = 24.37, <i>P</i> &lt; 0.001), indicating that habitat characteristics were similar to those selected by the aerially surveyed elk. Our <i>D</i><sup>2</sup> model indicated that the best elk habitat primarily occurred in northern and western Arkansas and was associated with areas of high landscape heterogeneity, heavy forest cover, gently sloping ridge tops and valleys, low human population density, and low road densities. To assess the potential for elk&ndash;human conflicts in Arkansas, we used the analytical hierarchy process to rank the importance of 8 criteria based on expert opinion from biologists involved in elk management. The biologists ranked availability of forage on public lands as having the strongest influence on the potential for elk&ndash;human conflict (33%), followed by human population growth rate (22%) and the amount of private land in row crops (18%). We then applied those rankings in a weighted linear summation to map the relative potential for elk&ndash;human conflict. Finally, we used white-tailed deer (<i>Odocoileus virginianus</i>) densities to identify areas where success of elk restoration may be hampered due to meningeal worm (<i>Parelaphostrongylus tenuis</i>) transmission. By combining results of the 3 spatial data layers (i.e., habitat model, elk&ndash;human conflict model, deer density), our model indicated that restoration sites located in west-central and north-central Arkansas were most favorable for reintroduction.</p>","language":"English","publisher":"Wildlife Society","doi":"10.2193/2005-673","issn":"0022541X","usgsCitation":"Telesco, R., Van

Long-billed curlews (Numenius americanus) are a species of special concern in North America due to apparent declines in their population. Because long-billed curlews are not adequately monitored by existing programs, we undertook a 2-year study with the goals of 1) determining present long-billed curlew distribution and breeding population size in the United States and 2) providing recommendations for a long-term long-billed curlew monitoring protocol. We selected a stratified random sample of survey routes in 16 western states for sampling in 2004 and 2005, and we analyzed count data from these routes to estimate detection probabilities and abundance. In addition, we evaluated habitat along roadsides to determine how well roadsides represented habitat throughout the sampling units. We estimated there were 164,515 (SE = 42,047) breeding long-billed curlews in 2004, and 109,533 (SE = 31,060) breeding individuals in 2005. These estimates far exceed currently accepted estimates based on expert opinion. We found that habitat along roadsides was representative of long-billed curlew habitat in general. We make recommendations for improving sampling methodology, and we present power curves to provide guidance on minimum sample sizes required to detect trends in abundance.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2193/2007-023","issn":"0022541X","usgsCitation":"Stanley, T., and Skagen, S., 2007, Estimating the breeding population of long-billed curlew in the United States: Journal of Wildlife Management, v. 71, no. 8, p. 2556-2564, https://doi.org/10.2193/2007-023.","startPage":"2556","endPage":"2564","costCenters":[],"links":[{"id":203365,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":18957,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2193/2007-023"}],"volume":"71","issue":"8","noUsgsAuthors":false,"publicationDate":"2010-12-13","publicationStatus":"PW","scienceBaseUri":"4f4e4a6be4b07f02db63d7e5","contributors":{"authors":[{"text":"Stanley, T.R.","contributorId":61379,"corporation":false,"usgs":true,"family":"Stanley","given":"T.R.","affiliations":[],"preferred":false,"id":346343,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Skagen, S.

We implanted sixty king eiders with satellite transmitters at nesting areas on the North Slope of Alaska, USA, in 2002-2004. More than 80% of marked eiders spent >2 weeks staging offshore prior to beginning a postbreeding molt migration. During postbreeding staging and migration, male king eiders had much broader distributions in the Alaskan Beaufort Sea than female eiders, which were concentrated in Harrison and Smith Bays. Distribution did not vary by sex during spring migration in the year after marking. Shorter residence times of eiders and deeper water at locations used during spring migration suggest the Alaskan Beaufort Sea might not be as critical a staging area for king eiders during prebreeding as it is postbreeding. Residence time in the Beaufort Sea varied by sex, with female king eiders spending more days at sea than males in spring and during postbreeding. We conclude the Alaskan Beaufort Sea is an important staging area for king eiders during postbreeding, and eider distribution should be considered by managers when mitigating for future offshore development. We recommend future studies examine the importance of spring staging areas outside the Alaskan Beaufort Sea.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2193/2005-636","issn":"0022541X","usgsCitation":"Phillips, L.M., Powell, A., Taylor, E., and Rexstad, E., 2007, Use of the Beaufort Sea by king eiders breeding on the North Slope of Alaska: Journal of Wildlife Management, v. 71, no. 6, p. 1892-1898, https://doi.org/10.2193/2005-636.","startPage":"1892","endPage":"1898","costCenters":[],"links":[{"id":203334,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":18964,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2193/2005-636"}],"volume":"71","issue":"6","noUsgsAuthors":false,"publicationDate":"2010-12-13","publicationStatus":"PW","scienceBaseUri":"4f4e4a17e4b07f02db604302","contributors":{"authors":[{"text":"Phillips, Laura M.","contributorId":49497,"corporation":false,"usgs":false,"family":"Phillips","given":"Laura","email":"","middleInitial":"M.","affiliations":[{"id":7211,"text":"University of Alaska, Fairbanks","active":true,"usgs":false}],"preferred":false,"id":346365,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Powell, A.N.","contributorId":66194,"corporation":false,"usgs":true,"family":"Powell","given":"A.N.","email":"","affiliations":[],"preferred":false,"id":346366,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Taylor, E.J.","contributorId":9752,"corporation":false,"usgs":true,"family":"Taylor","given":"E.J.","email":"","affiliations":[],"preferred":false,"id":346363,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Rexstad, E.A.","contributorId":47063,"corporation":false,"usgs":true,"family":"Rexstad","given":"E.A.","email":"","affiliations":[],"preferred":false,"id":346364,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Implementation of the plan under the adaptive management paradigm requires an understanding of the spatial and temporal structure of the population. We used polythetic agglomerative hierarchical cluster analysis of radiolocations obtained from free-ranging bison to investigate seasonal movements and aggregations. We classified radiolocations into 4 periods: annual, peak rut (15 Jul–15 Sep), extended rut (1 Jun–31 Oct), and winter (1 Nov–31 May). We documented spatial separation of Yellowstone bison into 2 segments, the northern and central herds, during all periods. The estimated year-round exchange rate (4.85–5.83%) of instrumented bison varied with the fusion strategy employed. We did not observe exchange between the 2 segments during the peak rut and it varied during the extended rut (2.15–3.23%). We estimated a winter exchange of 4.85–7.77%. The outcome and effectiveness of management actions directed at Yellowstone bison may be affected by spatial segregation and herd affinity within the population. Reductions based on total population size, but not applied to the entire population, may adversely affect one herd while having little effect on the other.

Potential management alternatives included existing roundup and selective removal methods combined with contraceptives of different duration and effectiveness. I projected costs for a 20-year economic life using the WinEquus?? wild horse population model and state-by-state cost estimates reflecting BLM's operational expenses. Findings revealed that 1) currently available 2-year contraceptives in most situations are capable of reducing variable operating costs by 15%, 2) experimental 3-year contraceptives may be capable of reducing costs by 18%, and 3) combining contraceptives with modest changes to herd sex ratio (e.g., 55-60% M) could trim costs by 30%. Predicted savings can increase when contraception is applied in conjunction with a removal policy that targets horses aged 0-4 years instead of 0-5 years. However, reductions in herd size result in greater variation in annual operating expenses. Because the horse program's variable operating costs make up about half of the total program costs (which include other fixed costs), contraceptive application and management can only reduce total costs by 14%, saving about $6.1 million per year. None of the contraceptive options I examined eliminated the need for long-term holding facilities over the 20-year period simulated, but the number of horses held may be reduced by about 17% with contraceptive treatment. Cost estimates were most sensitive to the oldest age adoptable and per-day holding costs. The BLM will experience significant cost savings as carefully designed contraceptive programs become widespread in the wild horse herds it manages.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2193/2007-064","issn":"0022541X","usgsCitation":"Bartholow, J., 2007, Economic benefit of fertility control in wild horse populations: Journal of Wildlife Management, v. 71, no. 8, p. 2811-2819, https://doi.org/10.2193/2007-064.","startPage":"2811","endPage":"2819","costCenters":[],"links":[{"id":203319,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":18956,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2193/2007-064"}],"volume":"71","issue":"8","noUsgsAuthors":false,"publicationDate":"2010-12-13","publicationStatus":"PW","scienceBaseUri":"4f4e4a4be4b07f02db625cd9","contributors":{"authors":[{"text":"Bartholow, J.","contributorId":62181,"corporation":false,"usgs":true,"family":"Bartholow","given":"J.","affiliations":[],"preferred":false,"id":346341,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Noninvasive survey methods increasingly provide means to collect extensive data on carnivore occupancy, distribution, and abundance. During the summers of 2003-2004, we compared the abilities of scat detection dogs, remote cameras, and hair snares to detect black bears (Ursus americanus), fishers (Martes pennanti), and bobcats (Lynx rufus) at 168 sites throughout Vermont. All 3 methods detected black bears; neither fishers nor bobcats were detected by hair snares. Scat detection dogs yielded the highest raw detection rate and probability of detection (given presence) for each of the target species, as well as the greatest number of unique detections (i.e., occasions when only one method detected the target species). We estimated that the mean probability of detecting the target species during a single visit to a site with a detection dog was 0.87 for black bears, 0.84 for fishers, and 0.27 for bobcats. Although the cost of surveying with detection dogs was higher than that of remote cameras or hair snares, the efficiency of this method rendered it the most cost-effective survey method.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2193/2006-292","issn":"0022541X","usgsCitation":"Long, R.A., Donovan, T., MacKay, P., Zielinski, W.J., and Buzas, J.S., 2007, Comparing scat detection dogs, cameras, and hair snares for surveying carnivores: Journal of Wildlife Management, v. 71, no. 6, p. 2018-2025, https://doi.org/10.2193/2006-292.","startPage":"2018","endPage":"2025","costCenters":[],"links":[{"id":203335,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":18965,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2193/2006-292"}],"volume":"71","issue":"6","noUsgsAuthors":false,"publicationDate":"2010-12-13","publicationStatus":"PW","scienceBaseUri":"4f4e4b24e4b07f02db6ae461","contributors":{"authors":[{"text":"Long, Robert A.","contributorId":11732,"corporation":false,"usgs":false,"family":"Long","given":"Robert","email":"","middleInitial":"A.","affiliations":[{"id":13253,"text":"University of Vermont","active":true,"usgs":false}],"preferred":false,"id":346367,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Donovan, T.M.","contributorId":91602,"corporation":false,"usgs":true,"family":"Donovan","given":"T.M.","email":"","affiliations":[],"preferred":false,"id":346371,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"MacKay, Paula","contributorId":37042,"corporation":false,"usgs":false,"family":"MacKay","given":"Paula","email":"","affiliations":[{"id":13253,"text":"University of Vermont","active":true,"usgs":false}],"preferred":false,"id":346369,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Zielinski, William J.","contributorId":35440,"corporation":false,"usgs":false,"family":"Zielinski","given":"William","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":346368,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Buzas, Jeffrey S.","contributorId":86080,"corporation":false,"usgs":false,"family":"Buzas","given":"Jeffrey","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":346370,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Embryos from the Lake Calumet, IL, colony had greater exposure to polychlorinated biphenyls (PCBs), 4,4'-dichlorodiphenyldichloroethylene (DDE), dieldrin, transnonachlor, oxychlordane, cobalt, copper, and selenium than did those from northwest MN and coastal VA. Embryos from IL and VA contained greater concentrations of mercury and zinc than those from MN, whereas the latter had greater accumulation of lead. Greater exposure of IL embryos to PCBs was reflected in greater ethoxyresorufin-O-deethylase and benzyloxyresorufin-O-dealkylase induction. However, measures of oxidative stress and genotoxicity were similar to those in embryos from the other colonies examined, and no overt toxic effects of contaminant exposure such as embryo mortality or malformations were observed. Although efforts to clean up the south Chicago environment are ongoing, Lake Calumet BCNH, and undoubtedly other piscivorous wildlife foraging in the region, continue to be exposed to a variety of environmental contaminants. Life-history characteristics of this species make it ideal as an environmental sentinel for the success of the cleanup of the south Chicago environment.</p>","language":"English","publisher":"BioOne","doi":"10.3394/0380-1330(2007)33[791:CEABRI]2.0.CO;2","usgsCitation":"Levengood, J., Wiedenmann, L., Custer, T., Schaeffer, D., Matson, C.W., Melancon, M.J., Hoffman, D.J., Scott, J., Talbott, J., Bordson, G., Bickham, J., Rattner, B., and Golden, N.H., 2007, Contaminant exposure and biomarker response in embryos of Black-crowned Night-herons (Nycticorax nycticorax) nesting near Lake Calumet, Illinois: Journal of Great Lakes Research, v. 33, no. 4, p. 791-805, https://doi.org/10.3394/0380-1330(2007)33[791:CEABRI]2.0.CO;2.","productDescription":"15 p.","startPage":"791","endPage":"805","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":201652,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Illinois","otherGeospatial":"Lake Calumet","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -87.60360717773436,\n              41.68060473460121\n            ],\n            [\n              -87.593994140625,\n              41.66521798508633\n            ],\n            [\n              -87.56858825683594,\n              41.66316614058965\n            ],\n            [\n              -87.56858825683594,\n              41.6980386041929\n            ],\n            [\n              -87.60017395019531,\n              41.69547509615208\n            ],\n            [\n              -87.60360717773436,\n              41.68060473460121\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"33","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4afee4b07f02db6976cf","contributors":{"authors":[{"text":"Levengood, J.M.","contributorId":57191,"corporation":false,"usgs":true,"family":"Levengood","given":"J.M.","affiliations":[],"preferred":false,"id":342878,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wiedenmann, L.","contributorId":61544,"corporation":false,"usgs":true,"family":"Wiedenmann","given":"L.","email":"","affiliations":[],"preferred":false,"id":342879,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Custer, T.

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.

We investigated phylogenetic relationships within the Furnariinae, with particular attention to the nine species of the genus Upucerthia, using nuclear and mitochondrial DNA sequences from all genera in the subfamily. <i>Upucerthia</i> was found to be highly polyphyletic, its constituent species forming four non-sister clades: (1) a basal lineage consisting of two <i>Upucerthia</i> species, <i>U. ruficaudus</i> and <i>U. andaecola</i>, as well as the monotypic genera <i>Eremobius</i> and <i>Chilia</i>; (2) a lineage consisting of U. harterti and <i>U. certhioides</i>, two species behaviorally divergent from other <i>Upucerthia</i> species; (3) a lineage consisting of <i>U. serrana</i>, which is not closely related to any other <i>Upucerthia</i> species; and (4) a lineage, sister to <i>Cinclodes</i>, consisting of the four <i>Upucerthia</i> species <i>U. dumetaria</i>, <i>U. albigula</i>, <i>U. validirostris</i>, and <i>U. jelskii</i>. The larger Furnariinae was also found to be highly polyphyletic; the terrestrial open country ecotype characteristic of this subfamily occurs in four unrelated clades in the family Furnariidae, including a basal lineage as well as derived lineages. Although the large degree of divergence among <i>Upucerthia</i> clades was not previously recognized, owing to ecological, behavioral, and morphological similarities, the groupings correspond closely to relationships suggested by plumage. This is in contrast to studies of other avian genera in which plumage patterns have been shown to be extensively convergent. The generic names <i>Upucerthia</i> and <i>Ochetorhynchus</i> are available for two of the former <i>Upucerthia</i> clades; new generic names may be warranted for the other two.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.ympev.2007.04.014","usgsCitation":"Chesser, R., Barker, F., and Brumfield, R., 2007, Fourfold polyphyly of the genus formerly known as Upucerthia, with notes on the systematics and evolution of the avian subfamily Furnariinae: Molecular Phylogenetics and Evolution, v. 44, no. 3, p. 1320-1332, https://doi.org/10.1016/j.ympev.2007.04.014.","productDescription":"13 p.","startPage":"1320","endPage":"1332","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":196133,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"44","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1be4b07f02db6a915d","contributors":{"authors":[{"text":"Chesser, R.T. 0000-0003-4389-7092","orcid":"https://orcid.org/0000-0003-4389-7092","contributorId":34616,"corporation":false,"usgs":true,"family":"Chesser","given":"R.T.","email":"","affiliations":[],"preferred":false,"id":342764,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Barker, F.K.","contributorId":68423,"corporation":false,"usgs":true,"family":"Barker","given":"F.K.","email":"","affiliations":[],"preferred":false,"id":342765,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Brumfield, R.T.","contributorId":24882,"corporation":false,"usgs":true,"family":"Brumfield","given":"R.T.","email":"","affiliations":[],"preferred":false,"id":342763,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

We examined the rates and processes of peat formation by mangroves of the Caribbean Region to better understand biological controls on habitat stability. Location Mangrove-dominated islands on the Caribbean coasts of Belize, Honduras and Panama were selected as study sites. Methods Biological processes controlling mangrove peat formation were manipulated (in Belize) by the addition of nutrients (nitrogen or phosphorus) to <i>Rhizophora mangle</i> (red mangrove), and the effects on the dynamics of soil elevation were determined over a 3-year period using rod surface elevation tables (RSET) and marker horizons. Peat composition and geological accretion rates were determined at all sites using radiocarbon-dated cores. Results The addition of nutrients to mangroves caused significant changes in rates of mangrove root accumulation, which influenced both the rate and direction of change in elevation. Areas with low root input lost elevation and those with high rates gained elevation. These findings were consistent with peat analyses at multiple Caribbean sites showing that deposits (up to 10 m in depth) were composed primarily of mangrove root matter. Comparison of radiocarbon-dated cores at the study sites with a sea-level curve for the western Atlantic indicated a tight coupling between peat building in Caribbean mangroves and sea-level rise over the Holocene. Main conclusions Mangroves common to the Caribbean region have adjusted to changing sea level mainly through subsurface accumulation of refractory mangrove roots. Without root and other organic inputs, submergence of these tidal forests is inevitable due to peat decomposition, physical compaction and eustatic sea-level rise. These findings have relevance for predicting the effects of sea-level rise and biophysical processes on tropical mangrove ecosystems.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkSubtype":{"id":10,"text":"Journal

A hierarchical Bayesian model is used to simultaneously correct for population-based sampling bias and estimate tornado density using historical tornado report data.  The expected result is that F2-F5 compared with F0-F1 tornado reports would vary less with population density.  The results agree with this hypothesis for the following population centers: Atlanta, Georgia; Champaign, Illinois; and Des Moines, Iowa.  However, the results indicated just the opposite in Oklahoma.  It is hypothesized that the result is explained by the misclassification of tornadoes that were worthy of F2-F5 rating but were classified as F0-F1 tornadoes, thereby artificially decreasing the number of F2-F5 and increasing the number of F0-F1 reports in rural Oklahoma.","language":"English","publisher":"AMS Publications","doi":"10.1175/WAF997.1","usgsCitation":"Anderson, C., Wikle, C.K.,

In practice, Bayesian analysis of such models has proved difficult because the dimension of the parameter space is not fixed, being in some cases a function of the unknown index.  We describe a data augmentation approach to the analysis of this class of models that provides for a generic and efficient Bayesian implementation.  Under this approach, the data are augmented with all-zero detection histories.  The resulting augmented dataset is modeled as a zero-inflated version of the complete-data model where an estimable zero-inflation parameter takes the place of the unknown multinomial index.  Interestingly, data augmentation can be justified as being equivalent to imposing a discrete uniform prior on the multinomial index.  We provide three examples involving estimating the size of an animal population, estimating the number of diabetes cases in a population using the Rasch model, and the motivating example of estimating the number of species in an animal community with latent probabilities of species occurrence and detection.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Computational and Graphical Statistics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"6818_Royle.pdf","usgsCitation":"Royle, J., Dorazio, R., and Link, W., 2007, Analysis of multinomial models with unknown index using data augmentation: Journal of Computational and Graphical Statistics, v. 16, no. 1, p. 67-85.","productDescription":"67-85","startPage":"67","endPage":"85","numberOfPages":"19","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202038,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":16869,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://pubs.amstat.org/doi/abs/10.1198/106186007X181425","linkFileType":{"id":5,"text":"html"}}],"volume":"16","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4acfe4b07f02db6802ff","contributors":{"authors":[{"text":"Royle, J.
