| Biodiversity, systematic, and conservation research in our laboratory involves a variety of genetic and morphological character sets on a variety of fish groups. For example, we have focused most of our research on species of the following families: Lampreys: Family Petromyzontidae Phylogeny of lamprey species of the world Species identification using molecular markers Testing the satelite speciation model Sturgeons: Family Acipenseridae Species diversity in Central Asian genus Pseudoscaphirhynchus Species differentiation in North American Scaphirhynchus Conservation genetics of imperiled species Scaphirhynchus and Pseudoscaphirhynchus based on mitochondrial and nuclear genes. Shiners and Minnows: Family Cyprinidae Phylogenetic relationships of shiner-like Cyprinids of North America Several studies of molecular and morphological variation in Notropis, Campostoma, Nocomis, Pteronotropis, and Hybopsis. Descriptions of new species in Notropis. Conservation genetics of imperiled species of Cyprinidae in North America. Suckers: Family Catostomidae Genetic and morphological diversity within Catostomus plebius. Description of Wall Canyon Sucker, Catostomus sp. Morphological variation in the Sacramento Sucker, Catostomus occidentalis. Trout: Family Salmonidae Genetic and morphological diversity in the Mexican rainbow trout lineage. Descriptions of new species of rainbow trout in Mexico. Conservation genetics of Mexican rainbow trout. Topminnows: Family Profundulidae Phylogenetic relationships of species of Profundulus Biogeography and conservation of Profundulus of southern Mexico. Sunfish and Bass: Family Centrarchidae Phylogenetic relationships of species of sunfishes and basses Genetic divergence and biogeography of species of Micropterus, Lepomis, and Ambloplites. Darters: Family Percidae Genetic and morphhological divergence in clades of Percina and Etheostoma. Conservation genetics of species of Percina and Etheostoma. |
