Unexpected consequences of polyandry for parasitism and fitness in the bumblebee, Bombus terrestris.

Evolution; international journal of organic evolution - 1 Aug 2001

Baer B, Schmid-Hempel P

Abstract excerpt

Multiple mating by females (polyandry) is taxonomically widespread but the evolution of such behaviors is not clearly understood given potential costs of polyandry such as time, energy, or predation risk. The genetic variability versus parasites hypothesis predicts a reduction of parasitism due to increased genetic variability among offspring and an associated fitness gain. We tested this hypothesis with a field...
