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.

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 ...

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 ...

Nesting of Podocnemis unifilis in the Capanaparo River, Venezuela
Journal of Herpetology, 1993(Pritchard and Trebbau, 1984). Although still abundant in many lowland riverine habitats in Venezuela, including the Capanaparo River, numbers appear to be declining because the terecay is a principal human food staple during the dry season, with both eggs and turtles being consumed or sold in large quantities throughout the species range (Mittermeier,

The use of pesticides is a widely spread practice in Brazilian agriculture, and dispersion of these substances is an important factor for the fauna and flora. Atrazine is an endocrine disruptor in the xenoestrogen class that is used worldwide in agricultural practices. In Brazil, its use is permitted in several crops.

Blood biochemistry and relations among Podocnemis turtles (pleurodira, pelomedusidae)
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1978Agglutination, precipitation and electrophoresis of hemoglobin and serum point to a core of five Podocnemis species (P. erythrocephala, P. expansa, P. lewyana, P. unifilis and P. vogli), with a sixth species (P. sextuberculata) fringing this cluster. 1. 2. In addition, the data indicate that P. dumeriliana and P.
