Sexual selection has long been proposed as a mechanism leading to the diverse cichlid (Teleostei: Cichlidae) fauna of Lake Malawi, Africa. Many of the shallow-water, sand-dwelling, bower-building cichlid species are particularly well suited for studies of sexual selection because they participate in leks. Since females in lekking systems appear to acquire(More)
Habitat partitioning among eleven species of darters (Percidae: Etheostomatini) from the Allegheny River system was studied through underwater observation. Percina caprodes and Percina copelandi showed consistent segregation from Etheostoma by occupying deeper habitats. Substrate size, depth, and water velocity were important variables by which Etheostoma(More)
