Using data from 288 adult and yearling female elk that were captured on 22 Wyoming winter supplemental elk feedgrounds and monitored with GPS collars, 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 5 plausible winter weather scenarios (from a heavy snow, to an extreme winter drought year). We then predicted abortion events by combining elk distributions with empirical estimates of daily abortion rates, spatially varying elk seroprevalence, and elk population counts. Here we provide the predicted abortion events on a daily basis at a 500m resolution for the 5 different weather...

The risk of disease transmission from domestic sheep to bighorns was evaluated using a proximity analysis of BLM sheep allotments in relation to bighorn sheep occupied habitat. BLM allotment data were used to identify active domestic sheep grazing locations and their distance to bighorn ranges. Habitat falling within 9 miles of domestic sheep allotments were scored as high risk of disease, habitat located between 9 to 15 miles of domestic sheep allotments were scored as fair and habitat located beyond 15 miles was considered to have low disease risk.

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)...

Using data from 288 adult and yearling female elk that were captured on 22 Wyoming winter supplemental elk feedgrounds and monitored with GPS collars, 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 5 plausible winter weather scenarios (from a heavy snow, to an extreme winter drought year). Here we provide the predictions of elk space use on a daily basis at a 500m resolution for the 5 different weather scenarios: 1) low snowfall year (2010), 2) average snowfall year (2012), 3) high snowfall year (2014), 4) hypothetical early snowmelt climate change scenario where spring green...

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.
