Abstract

CALLISTO, M. et al. Diversity and biomass of Chironomidae (Diptera) larvae in an impacted coastal lagoon in Rio de Janeiro, Brazil. Braz. J. Biol. [online]. 2002, vol.62, n.1, pp. 77-84. ISSN 1519-6984.  http://dx.doi.org/10.1590/S1519-69842002000100010.

Diversity and biomass of Chironomidae larvae were studied between January-November 1993 and March-November 1994 in an impacted lagoon in Rio de Janeiro, Southeastern Brazil, in an attempt to establish the ecological consequences of anthropogenic eutrophication processes. Nine hundred and seventy-five organisms belonging to the Tanypodinae, Orthocladiinae, and Chironominae were collected. Polypedilum (62%) and Chironomus (58%) were the most common genera found in the limnetic and littoral zones.

Keywords : biodiversity; eutrophication; chironomids; bioindicators; coastal lagoon.
