Canine distemper virus antibody titer results for grizzly bears and wolves in the Greater Yellowstone Ecosystem 1984-2014

We investigated the dynamics of canine distemper virus (CDV) in grizzly bears (Ursus arctos) and wolves (Canis lupus) of the Greater Yellowstone Ecosystem (GYE) using serological data collected from 1984 to 2014. 565 sera samples were obtained from 425 unique grizzly bears (134 females and 291 males) from 1984 to 2014 and 319 sera samples were obtained from 285 unique wolves %

Annual winter elk movements in the Greater Yellowstone Ecosystem 2001-2015

521 unique elk were monitored across several years with GPS collars in the Greater Yellowstone Ecosystem to determine winter-to-winter annual dispersal distances. There were a total of 704 annual movements. The dataset spans from 2001 to 2015. Annual movements were based on a single location in January or February and another location in the subsequent winter. An individual elk was included at...

Yellowstone Cutthroat Trout and Brown Trout capture-recapture data from Duck Creek, MT in summer and fall 2013-2016

We collected lengths and weights of Yellowstone cutthroat trout (Oncorhynchus clarkii bouvieri) and brown trout (Salmo trutta) above (Yellowstone cutthroat trout allopatry) and below (Yellowstone cutthroat trout sympatry with brown trout) a natural barrier in Duck Creek, Montana.

Yellowstone Cutthroat Trout and Brown Trout diet data from Duck Creek, MT in summer and fall 2015

We collected diets on Yellowstone cutthroat trout (Oncorhynchus clarkii bouvieri) and brown trout (Salmo trutta) above (Yellowstone cutthroat trout allopatry) and below (Yellowstone cutthroat trout sympatry with brown trout) a natural barrier in Duck Creek, Montana. We used gastric lavage methods to collect diets, and samples were placed in storage containers and taken back t

Maximum glacial extent of the named glaciers in Glacier National Park during the peak of the Little Ice Age

These polygon features represent the maximum extent of the 37 named glaciers in Glacier National Park and two glaciers on U.S. Forest Service’s Flathead National Forest land during the peak of the Little Ice Age (mid-nineteenth century). Glacial margins are based on moraine deposits that result from active glaciation, and do not depict perennial snow and ice. Moraines were digitize

Environmental DNA detection data of Northern pike (Esox lucius) using a portable, field-based platform and a lab-based platform

We tested the sensitivity of a portable, field-based environmental DNA (eDNA) platform relative to widely used lab-based eDNA approaches for detecting invasive northern pike (Esox lucius) in eight lakes on Alaska’s Kenai Peninsula. Raw data reported in this dataset report detect/non-detect data for technical replicates of water samples.

A comprehensive inventory of maximum glacial extent in Glacier National Park during the peak of the Little Ice Age

These polygon features represent the maximum extent of glaciers in Glacier National Park and two glaciers on U.S. Forest Service’s Flathead National Forest land during the peak of the Little Ice Age (mid-nineteenth century). Glacial margins are based on moraine deposits that result from active glaciation, and do not depict perennial snow and ice. The criteria used for determining wh

Carnivore Hotspots in Peninsular Malaysia

A raster surface identifying hotspots of conservation priority based on 375 location records (89 unique geographic locations) of 28 species of Carnivora in Peninsular Malaysia. Hot spot analysis was conducted by calculating the Getis-Ord Gi* (pronounced G-i-star) statistic, using IUCN Red List status rank for each species as a weighting variable. Raster cell values represent a kerne

Counts of American Pikas and Hoary Marmots in North Cascades National Park 2016-2017

USGS scientists counted American pikas (Ochotona princeps) and hoary marmots (Marmota caligata) in North Cascades National Park, Washington, USA during 2016. Hoary marmots were resurveyed in 2017, primarily by the National Park Service. Surveys occurred at sites of previous studies by Jason Bruggeman (pikas - 2009-2013), Aidan Beers (pikas - 2013-2015), and Roger Christo

Elk GPS collar data from National Elk Refuge 2006-2015

17 adult female elk were captured on or around the National Elk Refuge and monitored with GPS collars from 2006 to 2015. Each of these elk were monitored for 1 to 2 years and migrated from the National Elk Refuge to Yellowstone National Park during the spring. Here we provide the unique identifier for each individual elk, the date/time stamp of each GPS location, the GPS location of the elk...
