Part I: Images for Mesocarnivore Survey of Lassen Volcanic National Park, Klamath Network, 2017-2018
This is the first of two pages holding image data from this study. Remote camera stations were set up in Lassen Volcanic National Park from August to October 2017 and June to September 2018 to document occurrence of mesocarnivores and other wildlife. 126 cameras were set up at 32 primary sampling units (clusters of two to four cameras) throughout the park. Random locations for primary sampling units were chosen using a 3-km sampling grid over the park area. The dataset contains all species observed within the study time-frame, the date and time of observation and the number of individuals detected as well as identification for individual locations, cameras and images. Of the three target species of conservation...
This data release comprises 4 datasets used to measure the field metabolic rate, body composition, foraging success, behavior, and movement patterns of 9 female polar bears on the sea ice of the Beaufort Sea in April, 2014-2016 as well as 1 dataset used to measure the energetic cost of resting in an adult female polar bear at the San Diego Zoo, San Diego, CA. Wild bears were dosed with and had their blood analyzed for oxygen-18 and deuterium concentrations, equipped with GPS-enabled satellite video camera collars with tri-axial accelerometers, and blood was measured for serum urea and creatinine levels. The bear at the San Diego Zoo had her oxygen consumption measured while resting in a metabolic chamber.
Wildlife carcasses recorded by Montana Department of Transportation, Idaho Department of Fish & Game, and U.S. Fish & Wildlife Service were aggregated to the nearest mile marker for major roads of the U.S. Northern Rockies. WGA connectivity flowlines were intersected with the road network and attributed to the nearest mile marker, along with their connectivity ranking, which indicates their expected relative importance to maintaining westwide connectivity. Values for potential risk factors, including average annual daily traffic (AADT), functional class, number of lanes, road surface width, landscape condition of surrounding habitat, ruggedness of surrounding landscape, and topographic position relative to surrounding...

This dataset contains morphological measures of Pacific walruses sampled in the Chukchi and Bering Seas between 1972 and 1991. From 1972 through 1991 the Soviet Union employed industrial methods to harvest and process Pacific walruses to enhance the Russian Far East economy. Under the oversight of the Pacific branch of the Soviet All-Union Scientific Investigational Institute of Marine Fisheries and Oceanography (VNIRO), offshore harvesting crews worked from specialized marine mammal hunting ships (ZRS) throughout the spring, summer, and early autumn in the marginal sea ice habitats of the Bering and Chukchi Seas. They launched small (~7 m) wooden boats to approach walruses resting on ice pans, which were dispatched...
Remote camera stations were set up in Whiskeytown National Recreation Area from October 2018 to January 2019 to document occurrence of mesocarnivores and other wildlife. Forty-five single-camera sampling stations were setup throughout the park. Camera locations were chosen based on the Klamath Monitoring Network vegetation plots. The dataset contains all species observed within the study time-frame, the date and time of observation and the number of individuals detected, as well as identification for individual locations, cameras and images. Of the three target species of conservation concern (Pacific fisher (Pekania pennanti), Pacific marten (Martes caurina), and Sierra Nevada red fox (Vulpes vulpes nector)), only...
Remote camera stations were set up between 2016 and 2019 to document the occurrence of mesocarnivores and other wildlife in five Klamath Monitoring Network Parks (Crater Lake National Park, Lassen Volcanic National Park, Lava Beds National Monument, Oregon Caves National Monument and Whiskeytown National Recreation Area). The primary goal was to document the distribution of three mesocarnivore species of conservation concern: the Pacific fisher (Pekania pennanti), Pacific marten (Martes caurina) and the Sierra Nevada red fox (Vulpes vulpes necator). Sixty species were identified across all the parks. Pacific fisher were detected in Oregon Caves National Monument and Whiskeytown National Recreation Area. Pacific...
This dataset is one table with time-linked behavior data derived from video camera collars on polar bears on land near Churchill, Manitoba, Canada. Eighteen polar bears were equipped with video-camera collars (Vertex Plus collar with camera option, Vectronic Aerospace GmbH, Berlin, Germany) for 19 - 23 days in 2019, 2021, and 2022.
This dataset is two tables with data collected and derived from polar bears sampled in Alaska’s southern Beaufort Sea during 2008-2019. Collected data includes demographic and morphometric information and derived data includes mercury concentrations in hair samples. Ancillary data includes gut microbiome abundances, diversity indices, calculated body condition, and the proportions of prey species detected in individual bear diets. These data were used to determine whether gut microbiota community richness and diversity were associated with diet-acquired mercury.
This model is based on how dogs utilize wildlands near human habituation. These predators can have detrimental effects on wildlife populations (Alterio et al. 1998). We based our model on the data collected by Odell and Knight (2001) that investigated habitat utilization of these predators with regard to distance from housing and on the probability for a homeowner to possess a dog. We buffered both the populated areas and the campground distance layers in ARC/INFO using probability functions [P = 0.548 - 1.4589 * Distance (km)]. Any cell with distance less than 0.36km received a probability based on the function (0.556 to 0.001572) and all distances greater than or equal to 0.36km from populated areas or campgrounds...

Remote camera stations were set up in Lava Beds National Monument and Modoc National Forest from January to May 2018 to document occurrence of mesocarnivores and other wildlife. Thirty-three cameras were set up at 12 primary sampling units (clusters of one to four cameras) throughout the park. Potentially suitable habitat occurred in small patches in Lava Beds National Monument with cameras were placed in groups of one, two or three. To allow for more primary sampling units of four cameras, some cameras were installed in neighboring portions of Modoc National Forest. Cameras located in Modoc National Forest are considered part of the Lava Beds National Monument survey for the purposes of this study. The dataset...

These data consist of the fatty acid composition (percent of mass) of adipose tissue samples from polar bears in Alaska's southern Beaufort Sea. Fat biopsy samples were collected from polar bears that were either captured or biopsy darted along the north coast of Alaska or on offshore ice during March, April, or May from 2004 to 2016. The data also include an identification code unique to an individual bear, sex, age class, and the date of sample collection.
These data are the data for age, skull size, body length, and lean mass for Gates of the Arctic, Lake Clark, Kodiak, and Katmai, Alaska, 2013-2016.
These data are estimates of the proportional contributions of bearded seal, beluga whale, bowhead whale, and ringed seal to the diets of southern Beaufort Sea polar bears. Fat biopsy samples were collected from polar bears captured or biopsy darted along the north coast of Alaska or on offshore ice during March, April, and May from 2004 to 2016. Fatty acid data of the above four prey species were compiled from online sources (Bromaghin et al. 2015ab, USGS 2021) and one private source that has been used in several polar bear diet studies (Thiemann et al. 2008). Diet composition was estimated from polar bear adipose tissue fatty acid composition data (USGS 2023) using three methods: the original quantitative fatty...
Carnivore carcasses recorded by Montana Department of Transportation, Idaho Department of Fish & Game, and U.S. Fish & Wildlife Service were aggregated to the nearest mile marker for major roads of the U.S. Northern Rockies. Note that wildlife carcass collection and reporting protocols and frequency differ between states and among maintenance sections within states. Carcass presence should therefore be used only to explore general patterns and not for statistical inference.

This layer represents 5-year relative counts of wildlife carcasses collected by Idaho Transportation Department (ITD) personnel (2008-2012) or reported by the general public (2012) on or adjacent to state highway system (major) routes. To obtain relative counts, the 5-year total counts per mile, which included all wildlife species observed, were divided by the maximum observed calue (98) to give a relative 0-1 risk score. Total counts, which include all wildlife species observed, along with carnivore counts, which include only black bears, grizzly bears, mountain lions, and wolves, are provided. Counts were derived by identifying the nearest mile marker to each carcass point location, then counting the frequency...
These data are estimates of den emergence date, den site departure dates, and duration at den sites as well as post-emergence observations for female polar bears sampled in the southern Beaufort Sea subpopulation 1985-2016 and the Chukchi Sea subpopulation 2008-2017. The data were used to better understand the importance of time spent at the den site post-emergence. Emergence dates and departure dates were determined using collar temperature sensor data.
