Abstract: Boehler Lake is a 2.5 ha, dystrophic beaver pond.Samples of benthic and eponic fauna were collected over four seasons from April 1994 to January 1995.Four sampling stations representive of different habitats in the pond produced 5,117 individuals and 99 taxa represented by 1 family of nematodes, 3 families of annelids, 3 families of mollusks, 4 families of crustaceans, and 29 families of insects.Dipterans composed 86% of all individuals of insects found.Detritivors and predators dominated the collections.Chaoborus punctipennis and several taxa of Chironomidae were present at all stations throughout the study period.Physicochemical sampling of the pond revealed generally low dissolved oxygen concentrations, and predominantly acidic conditions during the study period.Based on a light/dark bottle study, gross primary productivity was calculated to be -0.10 mg/L oxygen/day.The extensive peat mat, shallow basin, and apparent collapse of the trophic structure indicate that Boehler Lake is in its final stages of succession as an aquatic habitat.©2001 Oklahoma Academy of Science
