Research in the Porter Lab combines natural history with molecular markers to study phylogenetic relationships, phylogeography, hybridization, conservation genetics, evolution of mating systems and alternate reproductive tactics (ARTs) in natural populations of fishes and other aquatic organisms. Projects typically involve both field and laboratory studies from freshwater ecosystems in the Eastern United States. Phylogenetic analyses are conducted at the species or population level using morphological and/or molecular methods including meristic, morphometric, osteology, pigment biochemistry, DNA sequence and mutation detection techniques. Phylogenetic trees are combined with biogeographic information to reveal historic hydrologic changes that have shaped the evolution and current distributions of aquatic organisms. Molecular markers and principals of population genetics are applied to the recovery efforts of threatened and endangered fishes. Genetic parentage analyses using microsatellite markers provide a wealth of information on the evolution of fish mating systems, ARTs, introgression and hybridization.
