    Research Interests

    I am primarily interested in ecological and evolutionary relat­ionships of fishes. During my 30-year career at the University of Southern Mississippi my work focused primarily on fishes occurring in two different systems: 1) the near-shore region of the central Gulf of Mexico, especially the high-energy beaches along barrier islands; and 2) the diverse freshwater fish fauna of Mississippi. Our studies of these systems included the impacts of biotic and abiotic factors on the persistence and stability of fish assemblages; ecological responses of fishes to altered environments; reproductive biology and habitat use, especially as related to conservation; and the behavior and ecology of anadromous fishes, especially sturgeon (Acipenseridae). 

    My work at MSB includes studies of the growth and ecology of the Roundtail Chub (Gila robusta) in the Yampa River, Colorado, in relation to the hydrologic regime. In addition, I am involved in more synthetic works, including a textbook to be published by University of California Press entitled, "Ecology of North American Freshwater Fishes."
