Abstract
Abstract: The objective of this study was to inventory the community of cladocerans associated with macrophytes in oxbow lakes of the Chandless River, located within the Chandless State Park, during the local dry season. In three lakes covered with macrophytes, 90 sample units were collected, arranged over nine transects. Twenty species of cladocerans were found, which 16 are new records for the state of Acre. Mascote Lake had the largest abundance and richness, while São João Lake had the lowest indexes. The Shannon-Wiener index points to an average diversity within the work area, probably due to the difference in richness and abundance between the lakes.

The flood pulse promotes an homogenizer effect (Thomaz et al 2007). These local flood pulses are extremely important for the local diversity of cladocerans (Guntzel et al 2010), including those that interact with aquatic plants, the phytophilous cladocerans
When analyzing the species of cladocerans registered for Acre state, we found only 17 records
Summary
Resumo: O objetivo desse estudo foi inventariar a comunidade de cladóceros associados às macrófitas aquáticas em três lagos de meandro do rio Chandless, dentro do Parque Estadual Chandless, no período da estação seca local. The cladocerans reach their largest diversity in lentic environments (Rocha et al 2011), because they present better conditions for this type of organism, specially when we consider that most of the species are not effective swimmers (Bolduc et al 2020). Another contribution to the scarcity of phytophilous cladocerans data is the frequency of most studies in the limnetic zone. The group continues to be scarcely sampled in the Amazon
