Abstract

Faunistic and ecological characterization of aquatic and semiaquatic Heteroptera (Insecta) communities in permanent swamps situated in Făgăraş Depression and Sibiu Depression (Romania) This paper assesses the biodiversity of aquatic and semiaquatic Heteroptera in permanent swamps situated in two contact depressions between Făgăraş Mountains and the Transylvania Plateau, and performs a species association and a species monthly dynamics analysis. We have identified 30 species of Heteroptera, of which 18 species are aquatic (Infraorder Nepomorpha) and 12 are semiaquatic (Infraorder Gerromorpha). The α-biodiversity analysis reveales values between 0.379-3.475 for the investigated stations, which indicate a uniform distribution of individuals on species, both within stations and in each of the two depressions. The monthly sampling, in 2004, enabled us to analyze the species dynamics.
