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 in UTMs and Lat-Long, the month of each GPS location, the year of each GPS location, and the date of each GPS location in numeric form.

288 adult and yearling female elk were captured on 22 Wyoming winter supplemental elk feedgrounds and monitored with GPS collars during the brucellosis risk period (February – July) from 2007 to 2015. There were 4 to 64 individual elk per feedground and each elk was monitored for 1 to 2 years. Here we provide the unique identifier for each individual elk, the GPS location of the elk, the date/time stamp of the GPS location, and the feedground the elk was captured on in Wyoming.

Using data from 288 adult and yearling female elk that were captured on 22 winter supplemental elk feedgrounds in Wyoming and monitored with GPS collars from 2007 - 2015, we fit Step Selection Functions (SSFs) during the spring abortion season and then implemented a master equation approach to translate SSFs into predictions of daily elk distribution for five plausible winter weather scenarios (from a heavy snow, to an extreme winter drought year). We predicted elk abortion events by combining elk distributions with empirical estimates of daily abortion rates, spatially varying elk seroprevalence, and elk population counts. Here we provide 1) the adult and yearling female elk GPS collar data used to fit SSFs, 2)...

We calculated mean adult and yearling female elk abundance for each Wyoming winter supplemental feedground subpopulation for data collected from 2009 to 2015. In addition, the average seroprevalence of brucellosis in elk attending feedgrounds was based on blood samples from adult and yearling female elk from 1993 to 2015. The sample size of disease tests and the number of years over which they were collected on each feedground are also listed. Serological profiles were categorized using the 2003 U.S. Department of Agriculture brucellosis eradication uniform methods and rules for cervids. These serological tests indicate whether or not an individual has been exposed, but not whether they are currently infected.
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
