Taming Of The Skew: Transactional Models Fail To Predict Reproductive Partitioning In The Paper Wasp Polistes Dominulus, Aviva Liebert, Philip Starks

Aviva E Liebert

Female Polistes paper wasps can initiate colonies either solitarily or in cooperative groups. Reproduction is often distributed unequally in groups, even to the point of complete monopolization of breeding by the dominant group member. Transactional models of reproductive skew predict the degree of reproductive partitioning, assuming that the dominant controls group membership and will yield a proportion of reproduction to a subordinate as an incentive to stay peacefully in the group. Using a combination of demographic, genetic and morphological data from a population of P. dominulus, we test predictions of 'classical' two-person skew models as well as more complex …
