Risky movements? Natal dispersal does not decrease survival of a large herbivore

Eric Long, Duane Diefenbach, Clayton Lutz, Bret Wallingford & Christopher Rosenberry
Natal dispersal is assumed to be a particularly risky movement behavior as individuals transfer, often long distances, from birth site to site of potential first reproduction. Though, because this behavior persists in populations, it is assumed that dispersal increases the fitness of individuals despite the potential for increased risk of mortality. The extent of dispersal risk, however, has rarely been tested, especially for large mammals. Therefore, we aimed to test the relationship between dispersal and...
