Uma revisão sobre padrões de atividade, reprodução e alimentação de cágados brasileiros (Testudines, Chelidae)
Abstract
A review on activity patterns, reproduction, and feeding habits in Brazilian chelid turtles (Testudines, Chelidae).The knowledge on natural history of some Brazilian chelonian species is still scarce what makes it difficult to ascertain ecological andevolutionary histories. Data like this, however, can be used as fundamental tools for species management and conservation. A survey was made on the activity patterns, reproduction, and feeding behavior of Brazilian Chelidae species (freshwater sidenecked turtles) available in the literature. A clear lack of information regarding natural history is evident for most species. The species diversity and the biological importance of this taxon regard it as an interesting target to be studied. Since several Chelidae behaviors (including those reported in this study) are considered stereotyped, I suggest that laboratory studies should be encouraged as a way of complementing the field research.
