Abstract

"In a lentic ecosystem the trophic levels are usually accompanied by structural changes in the biota. One of the ways to establish such changes in a short time is the rapid biodiversity assessment, based on the discrimination of morphospecies instead of the identification of the genera and species levels. We evaluated the biodiversity of the benthic community of five lakes of the VIII Region of Chile (Chica y Grande de San Pedro, Lleu-Lleu, Qui
