Predation patterns on the tundra – genetic barcoding of scats from two sympatric fox species ...
In the Arctic tundra, climate-induced emergence of the red fox (Vulpes vulpes), a competitor to the Arctic fox (Vulpes lagopus), is predicted to influence predation patterns of both fox mesopredators. In this study, we i) identified predator species from scats through an established barcoding approa...
