Competition and Coexistence among the Grazing Snail Lymnaea, Chironomidae, and Mircrocrustacea in an Arctic Epilithic Lacustrine Community
Effects of the grazing activity of the gastropod Lymnaea elodes (arctica?) on animal community structure in the rocky littoral of an arctic lake were examined. In situ caging experiments on natural substrates with various snail densities resulted in shifts in faunal biomass abundance and distributio...
