dc.description.abstract
While inbreeding avoidance is widely accepted as the major driver of female
natal dispersal, the evolution of male philopatry is still poorly understood
and discussed to be driven by male mating strategy, mate competition among
male kin and kin cooperation. During a twelve-year study, we gathered detailed
genetic and observational data of individually marked proboscis bats to assess
the degree of male philopatry as well as its costs and benefits to improve the
understanding of its evolution. Our results reveal several patrilines with
simultaneous presence of closely related males and a small proportion of
unrelated immigrant males in their colonies. Philopatric males benefit from
avoiding the costs of immigration into foreign colonies through significantly
longer tenure, better integration (i.e. frequent nocturnal presence in the
colonies) and consequently significantly higher reproductive success compared
to immigrant males. Finally, we illustrate that despite a high proportion of
philopatric males in the groups, the number of closely related competing males
is low. Thus, the hypothesised costs of mate competition among male kin seem
to be low in promiscuous mammalian societies with unrelated females and a
small degree of male immigration and are readily outweighed by the benefits of
staying in the natal group.
