Geological control of Podocnemis expansa and Podocnemis unifilis nesting areas in Rio Javaés, Bananal Island, Brazil [PDF]
Acta Amazonica, 2003 The distribution of the nests of Podocnemis expansa (Amazon turtle) and Podocnemis unifilis (yellow-spotted side neck turtle) along the point bars of the Javaés River in Bananal Island, demonstrates a clear preference of these chelonians for differentiated geological environments, in respect to the morphology, grain size or height of the nests in ...

ABSTRACT Subsurface temperature variation suggests that the thermal environment of giant Amazon river turtle (Podocnemis expansa) nests is influenced by the proximity of the water table and by the nest depth. The difference between vertical temperature gradients along fluvial beaches indicates that nest placement can exert a significant influence on ...

The Arrau River turtle (Podocnemis expansa) is one of the largest side-neck turtles which listed as an endangered species in IUCN red list. In this study, the complete mitochondrial genome of P. expansa was determined by the sequencing of PCR fragments. The complete mitochondrial genome of P.

Abstract This work analyses the influence that nest site characteristics have over natural incubation in freshwater turtles Podocnemis expansa and Podocnemis unifilis. Results indicate that neither carapace size nor weight of P. expansa hatchlings depends on environmental characteristics.

Fertile eggs of Podocnemis expansa and Podocnemis unifilis were investigated for the presence of enterobacteria, as these two endangered species have the potential for conservation measures that include egg transfer. Knowledge of normal microflora associated with turtles and turtle eggs would help effectively manage the transfer of these eggs among ...

Avaliação da predação de Podocnemis expansa e Podocnemis unifilis (Testudines, Podocnemididae) no rio Javaés, Tocantins [PDF]
Acta Amazonica, 2009 Podocnemis expansa e P. unifilis são animais de vida longa, com uma demorada maturação sexual, o que influencia uma baixa taxa de substituição de indivíduos. Suas populações são caracterizadas por uma pequena mortalidade dos animais adultos, mas alta taxa de mortalidade de filhotes e embriões.
