The oldest, largest and deepest lake in Africa, Tanganyika is an exceptional place to study speciation processes because it houses and maintains an extraordinary endemic rich fauna of cichlid fish, molluscs and arthropods, including ostracodes. I have focused on one ostracode clade, Gomphocythere, to address questions concerning speciation, paleoecology, time-averaging, and morphologic stability. I have one Master's degree student presently working on a project entitled: Species Morphological Variability in Lake Tanganyika, East Africa, and have several other on-going projects there in conjunction with our NSF funded study entitled: High Resolution Paleoecology in a Complex Tropical Ecosystem (Lake Tanganyika, Africa) and the Development of Paleoecological Models for Lake Conservation Biology.
