Description

Sexual selection, both female mate choice and male-male aggression, has been important in the rapid and explosive evolution of the cichlid fishes of Lake Mala?i, Africa. In this study, we take a unique approach to the study of aggression by examining aggression in a pair of closely-related, sympatric species of the genus Labeotropheus. We hypothesize that males of both Labeotropheus fuelleborni and L. trewavasae will be more aggressive towards conspecific males than they will to those of the other species. The results of this study will demonstrate how behavioral barriers can promote the evolution of new species.
