Title: Amphibian communities under diverse forest management in the Ouachita Mountains, Arkansas
Author: Fox, Stanley; Shipman, Paul; Thill, Ronald; Phelps, Joseph; Leslie, David
Abstract: From May 1995 to March 1999, we censused amphibians in the Ouachita Mountains, Arkansas, on 60 plots on each of four forested watersheds five times per year, with new plots each year. We found negligible differences in species richness among watersheds, and community similarities were high, even though most pairwise comparisons were significantly different. The two most intensively managed watersheds were more similar to each other than to those less intensively managed, and the former had nominally higher overall species evenness and (beta) diversity. At the plot level, we found no significant differences in abundance, species richness, or (alpha) diversity, although the two most intensively managed watersheds had plots with fewer species and less diversity. Detrended correspondence analysis revealed that communities diverged on the basis of presumed gradients of terrestrial-aquatic, elevation, and canopy cover. Important communities that differed among watersheds were those of small, often ephemeral ponds and large, permanent ponds.
