Mate fidelity and intra-lineage polygyny in greater horseshoe bats

Article Abstract:

The mating strategies that lead to increased kinship within socially cooperative groups might offer inclusive fitness benefits to individuals but can also result in higher levels of inbreeding. When females engage in mate fidelity and intra-lineage polygyny, kin ties among female roost mates would be strengthened, there by potentially contributing to social group cohesiveness.
