Abstract

Understanding the forces that influence natural selection is a basic question in biology. Often these forces may conflict and result in trade-offs that affect the outcomes of selection. The research proposed here will integrate sexual selection and foraging theory to better understand the behavior of birds at leks and how such behavior impacts reproductive success and physiological condition of those birds. Lek-mating systems, where males gather in space to display for females and females select mates and then solely care for their offspring, provide an ideal system for this novel integration of sexual selection and foraging theory. Within these systems, the opportunities for strong sexual selection are possible because of strong variance in male reproductive success - few males actually mate with females. Second, studies have shown that lek attendance is a good correlate of male reproductive success, which means that there is potentially strong pressure to minimize time spent away from the leks conducting other activities, like foraging. Therefore, reproductively successful males are likely also efficient foragers. The proposed study will test this hypothesis using a combination of observations and experiments using the white-bearded manakin, Manacus manacus, in Atlantic forests sites of São Paulo. The proposed research initiates a new collaboration between labs at University of Florida and UNESP-Rio Claro that have complementary strengths in studies of sexual selection and fruit-foraging and energetics.
