Ecology, Evolution and Physiology of Fishes

 

One of the greatest challenges in biology is to explain observed levels and patterns of species diversity. My research focuses on pieces of this puzzle on a variety of organizational levels from the physiology of individuals to the large scale temporal and spatial dynamics of assemblages. My lab typically uses freshwater fishes as model organisms to address these questions. Much of my recent work has focused on fishes in the Fundulus notatus species complex. The three described species in this group are ecologically and morphologically very similar and abundant throughout the Mississippi basin and Gulf of Mexico drainages from the Florida panhandle to southeastern Texas. The two most widely distributed members of this complex, F. notatus and F. olivaceus, cooccur and hybridize in replicate contact zones throughout much of that area. These contact zones are ideal systems for addressing a number of pertinent questions in the evolutionary ecology of fish.

 

USM Ichthyological Collection

The USM Museum of Ichthyology is an invaluable resource for students and researchers interested in ichthyology. The museum currently contains more than 46,000 lots and 1,100,000 specimens representing over 870 taxa.
