How the movement characteristics of large marine predators influence estimates of their abundance
Published online on 18. July 2015 How the movement characteristics of large marine predators influence estimates of their abundance Fabio Boschetti, Mathew A. Vanderklift ABSTRACT: Understanding animal movement provides information that helps design effective conservation initiatives. We intuitively understand that the way animals move at large scales determines the extent of their home range and
