Community-wide mesocarnivore response to partial ungulate migration
1.Mesocarnivores increase in number and geographic range in human-disturbed ecosystems with cascading negative impact on biodiversity. To mitigate such impacts, it is essential to identify the proximate causes of such mesocarnivore releases. Here, we assess to what extent increased partial migration...
