Life History of the Yazoo Darter (percidae: Etheostoma Raneyi), a Species Endemic to North-central Mississippi

The Yazoo darter, Etheostoma mneyi, is restricted to tributaries of the Little Tallahatchie and Yocona Rivers (Yazoo River drainage) in north-central Mississippi. The species inhabits small, clear streams, many of which are spring-fed, and have a variety of substrate types including silt, clay, sand and gravel. In Morris Creek, a second-order stream in Lafayette County, Mississippi, E. runeyi w...

Phylogenetic and coalescent strategies of species delimitation in snubnose darters (Percidae: Etheostoma).

The rapid accumulation of multilocus data sets has led to dramatic advances in methodologies for estimating evolutionary relationships among closely related species, but relatively less advancement has been made in methods for discriminating between competing species delimitation hypotheses. Multilocus data sets provide an advantage in testing species delimitation scenarios because they offer a...

Fucosidases of Sperm and Milt in Darters (Percidae: Etheostomatini)

Darters (Percidae: Etheostomatini) offer attractive opportunities for analysis of the evolution of reproductive barriers and the molecular basis of fertilization. Here we report some basic characteristics of the sperm of darters, and, to our knowledge, the first report of sperm associated -L-fucosidase in fishes. Fluorometric enzyme assays using 4methylumbelliferyl-alpha-L-fucopyranoside [4-MU-...

Gene trees reveal repeated instances of mitochondrial DNA introgression in orangethroat darters (percidae: etheostoma).

Phylogenies of closely related animal species are often inferred using mitochondrial DNA (mtDNA) gene sequences. The accuracy of mtDNA gene trees is compromised through hybridization that leads to introgression of mitochondrial genomes. Using DNA sequences from 6 single-copy nuclear genes and 2 regions of the mitochondrial genome, we investigated the temporal and geographic signature of mitocho...

Phylogeography of the greenside darter complex, Etheostoma blennioides (Teleostomi: Percidae): a wide-ranging polytypic taxon.

The greenside darter, Etheostoma blennioides (Teleostomi: Percidae), is a wide-ranging polytypic taxon that occurs throughout eastern North America. A previous morphological study recognized four subspecies (blennioides, newmanii, gutselli, and pholidotum), several morphological races, and three zones of morphological intergradation. We generated complete cytochrome b (1140bp) sequence data for...
