Host movement dominates the predicted effects of climate change on parasite transmission between wild and domestic mountain ungulates

Royal Society Open Science
Climate change is shifting the transmission of parasites, which is determined by host density, ambient temperature and moisture. These shifts can lead to increased pressure from parasites, in wild and domestic animals, and can impact the effectiveness of
