Variable mating strategies and incest avoidance in cooperating breeding grey-crowned babblers
Understanding cooperative breeding requires an appreciation of the direct and indirect reproductive benefits available to group members, alongside the costs of group living such as increased potential for inbreeding. We use molecular techniques to determine sex, kinship and parentage to explore the benefits of helping and the mechanisms for incest avoidance in cooperatively breeding grey-crowned babblers, Pomatostomus temporalis. Generally, helpers gained only indirect fitness benefits through...[Show more]
