ABSTRACT
Abstract A zooplankton checklist is presented for the Middle Xingu River, based on surveys conducted at four sites in the main channel and two fluvial lakes. A total of 175 taxa are listed, including 141 rotifers, 20 cladocerans, and five copepods. Rapids presented the greatest species richness, with up to 124 taxa, while Ilha Grande lake had 70 taxa, the lowest number. Non-planktonic benthic larvae were recorded frequently in the samples.
RESUMO
Resumo Levantamentos realizados em dois lagos e no canal principal do médio Xingu objetivaram a listar a diversidade do zooplâncton. De um total de 175 táxons, 141 foram rotíferos, 20 cladóceros e 5 copépodes. As corredeiras foram os ambientes mais diversos com 124 táxons, enquanto que no Lago da Ilha Grande se registraram somente setenta táxons. Destaca-se a ocorrência de grupos de hábito não planctônico na coluna d’água do rio que indica o efeito perturbador da correnteza.
