“…For example, population genetic variation is strongly structured across broadtail madtom (Noturus) populations, including a strongly supported Pee Dee River clade (Bennetts et al, 1999). Genetic variation among Coastal Plain pygmy sunfishes (Elassoma) is also characterized by significant among-drainage divergence (Quattro, Jones & Rohde, 2001b). Both mtDNA and nuclear allelic distributions are highly structured for the Altamaha River and Savannah River populations of the robust redhorse Moxostoma robustum (Wirgin et al, 2001).…”

Comparing variation across evolutionarily independent characters, notably nuclear and mitochondrial genes, yields a more robust estimate of diversification than is generally recovered from individual characters. Patterns of variation across multiple molecular markers from the mitochondrial (16SrRNA, cytochrome b) and nuclear (ldhA6 and aldB) genomes were examined from six populations of Etheostoma collis and two populations of Etheostoma saludae, species aligned in the collis groups. Phylogenetic analyses revealed that sequence variation among individuals from the Roanoke, Tar and Neuse Rivers and the Catawba and Pee Dee Rivers, respectively, form highly supported, deeply divergent clades. Relationships of alleles sampled from Saluda River E. saludae and Cape Fear River E. collis to these lineages are unresolved, but all groups are reciprocally monophyletic for both nuclear and mtDNA loci. Phylogenetic analyses suggest that historical factors have had a strong influence on the distribution of genetic variation among populations. Genetic variation within the collis group is consistent with all previously proposed taxonomic hypotheses for the collis group, providing no taxonomic insights. From a conservation standpoint, each population of the collis group is an ESU, thereby warranting a drainage-specific management strategy.

“…It is listed by the State of Georgia as (S1), critically imperiled because of extreme rarity. The Savannah River and Edisto River populations are sufficiently genetically distinct that they should be managed separately (Quattro et al 2001a). …”

“…This species is known only from the New River, Edisto River, and Savannah River drainages in South Carolina and Georgia (Quattro et al 2001a). Within the Savannah River drainage, it is found as far west as Boggy Gut Creek in Richmond County, Georgia (Rohde and Arndt 1987).…”
