Abstract

The aquatic metazoan fauna and physicochemical features of the Silver Lake Fen, Dickinson County, Iowa, were investigated. The pools displayed high values of alkalinity, calcium and total hardness, sulfate and dissolved solids; neutral to alkaline conditions; and extreme diurnal variability in dissolved gasses, pH and temperature. Fifty metazoan species have been collected from this unique and rigorous habitat, with nine species being most abundant and widespread. Possible causal factors dealing with population dispersion are discussed.
