Dispersal and immigration strategies in primate males

PASCAL R. MARTY

Abstract


Males of most socially living primate species disperse to other social groups in
order to increase their reproductive success by avoiding the costs of inbreeding or selective pressure from within group competition. These dispersal events represent a fundamental shift in social life and environment in a male's life. Specifically, dispersal brings vital benefits, such as inbreeding avoidance, but also significant costs such as increased predation risk and male-male competition. As a consequence of such tradeoffs, evolution favors strategies that enable males to increase their future reproductive success while minimizing the costs. Here I give a short overview over the behavioral and physiological adaptations primate males use to maximize the benefits and minimize the costs of dispersal.
