Attacked from two fronts: Interactive effects of anthropogenic and biotic disturbances generate complex movement patterns
Anthropogenic and biotic disturbances have the potential to interact, generating cumulative impacts on animal movement or, alternatively, counterbalancing or masking each other. Despite their importance, those interactions have not been investigated thoroughly. Our study aimed to fill this knowledge gap by assessing the combined effects of a human activity—that is, military exercises—and a biotic disturbance—that is, insect harassment—on movement rates of free-ranging semidomesticated reindeer (Rangifer tarandus tarandus).
