The rosyside dace, although abundant throughout the eastern Appalachians, is listed as an endangered species in Ohio. It inhabits the headwater streams of south-central Ohio. Patterns of variation at four polymorphic loci (Adh, Ldh, Pgd, and Xdh) were analysed to determine the degree of interpopulation differentiation. Several characteristics (headwater resident, subject to annual stream drying, likely severe population crashes and flushes) of this species and its populations suggested that the rosyside dace should exhibit low intrapopulation variation and high interpopulation differentiation. The results were consistent with these predictions.
