Summary

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 scenarios: 1) low snowfall [...]

Purpose

These data were collected to assess the risk of brucellosis transmission between elk and cattle in this system. This data provides predictions on the location and number of elk abortions events to occur each year across varying snow and green-up dynamics in the study area, which can be used to predict how brucellosis transmission risk will change within and among years. Actual brucellosis risk to cattle may change over time as elk populations and disease prevalence varies. The predictions we provide are based on data collected up to 2015, but may not be accurate as conditions change over time.
