Elk distribution and spatial overlap with livestock during the brucellosis transmission risk period
Summary 1. The presence of Brucella abortus within free‐ranging wildlife populations is an important conservation and management issue because of the risk of brucellosis transmission between wildlife and livestock. Predicting wildlife distributions is necessary to forecast wildlife and livestock spa...
