          Abstract

          Podocnemis expansa (tartaruga-da-amazônia) é o maior e mais importante representante da fauna de quelônios da Amazônia devido à sua importância econômica como fonte alimentar para as populações indígenas e ribeirinhas desta região. Apesar disso, os aspectos relacionados à sua biologia reprodutiva, assim como os índices de predação natural de animais adultos em seu habitat são pouco conhecidos. Nessa pesquisa foi averiguado o número de fêmeas de P. expansa predadas por Panthera onca (onça-pintada) em um rio da Amazônia Brasileira. A onça-pintada é o único predador das fêmeas adultas de P. expansa nas praias do rio Javaés, Estado do Tocantins, predando em média 3,66% das fêmeas em postura. A predação se dá sempre à noite, quando as fêmeas sobem às praias para nidificar.

          Translated abstract

          Podocnemis expansa (Amazonian giant River turtle) is the largest and more important representative of the Amazonian turtle's fauna because their economic importance as food resource to the indigenous and riverine populations. Aspects related to their reproductive biology, and natural predation of adults in its habitat are poorly known. In order to estimate the predation rates of females of P. expansa we have registered the number of turtles with signs of been killed by Panthera onca (jaguar) in a River of the Brazilian Amazon. Jaguar was the only predator of the adult females of P. expansa in the Javaés River beaches (Tocantins State), predating about 3.66% of the females (33 of 901). Predation always happens at night, when females leave water in order to nest.
