Population censuses were conducted in line transects in 1999 and 2000 along the Transpantaneira Park Road in Poconé-MT, and 2002 and 2003 census birds were performed in 20 therealong lakes highway. They determined the species composition and abundance variation of the throughout the year and in subsequent years. It was found the role of abiotic factors (rainfall, air temperature, heat stroke, size and depth of the lake, temperature, transparency and water pH) and biotic (cover and species richness aquatic weeds, and biomass and richness of fish species) to predict the variation wealth and abundance and species composition of aquatic birds and piscivorous the Pantanal. / Assembléias de aves aquáticas e piscívoras foram estudadas durante quatro anos no Pantanal Matogrossense. Foram realizados censos populacionais em transectos lineares em 1999 e 2000 ao longo da Estrada Parque Transpantaneira em Poconé-MT, e em 2002 e 2003 foram realizados censos das aves em 20 lagos ao longo da mesma rodovia. Foram determinadas a composição de espécies e a variação da abundância ao longo do ano e em anos subseqüentes. Foi verificado o papel de fatores abióticos (pluviosidade, temperatura do ar, insolação, tamanho e profundidade do lago, temperatura, transparência e pH da água) e bióticos (cobertura e riqueza de espécies de macrófitas aquáticas, e biomassa e riqueza de espécies de peixes) em prever a variação na riqueza e abundância e na composição de espécies de aves aquáticas e piscivoras no Pantanal.
