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...

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.

We investigated the time to removal of bovine fetal materials, meant to simulate elk abortion materials, by scavengers in southwest Montana at 233 sites in February – June 2017 and 2018. Scavengers are likely to reduce the transmission risk of brucellosis, a bacterial disease that can lead to reproductive failure in infected elk, by consuming and removing infectious fetal materials from the landscape. Sites were monitored using remote, motion-detecting cameras until the fetal materials were consumed or removed by scavengers. Here we provide: 1) the time to removal of fetal materials by scavengers, 2) scavenger and ungulate activity at the remote camera sites, and 3) descriptions of the 13 study locations in southwest...
