Resumo: The zooplanktonic community of Lake Paranoá has been studied for more than thirty years. Until 1998, when it was considered eutrophic, only three cladoceran species were known from the reservoir. Since 1999, when Lake Paranoá underwent intentional flushing, definite changes in species diversity and composition were identified. At the same time, exploratory studies on littoral cladoceran species were being done. The present study aims to provide additional information on the cladoceran species composition of Lake Paranoá. Seven new species records are presented, four of them also representing the first record from the Federal District (Brasília). The population previously considered as belonging to Bosmina longirostris was reconsidered and re-identified as Bosmina freyi. Figures and comments on species taxonomy and distribution are also provided. _______________________________________________________________________________ ABSTRACT

Até 1998, quando o reservatório era considerado eutrófico, apenas 3 espécies de cladóceros haviam sido registradas. Com a aceleração do processo de reoligotrofização, a comunidade planctônica apresentou pronunciadas modificações. Ao mesmo tempo, estudos exploratórios das espécies litorâneas de cladóceros foram desenvolvidos. O objetivo do presente trabalho é apresentar informações adicionais sobre a composição de cladóceros do Lago Paranoá. São apresentados sete novos registros de ocorrência, sendo quatro deles também o primeiro para o Distrito Federal. A espécie anteriormente identificada como Bosmina longirostris foi revista, o que acarretou sua reidentificação como Bosmina freyi. Ilustrações e comentários sobre a taxonomia e distribuição das oito espécies são apresentados.2010-11-17T11:53:08Z2010-11-17T11:53:08Z2004info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfELMOOR-LOUREIRO, Lourdes M.
