A trophic study of the sympatric Amazonian freshwater turtles Podocnemis unifilis and Podocnemis expansa (Testudines, Podocnemidae) using carbon and nitrogen stable isotope analyses
(CANADIAN SCIENCE PUBLISHING, NRC RESEARCH PRESSOTTAWA, 2012)
The Yellow-spotted River Turtle (Podocnemis unifilis Troschel, 1848) and the South American River Turtle (Podocnemis expansa (Schweigger, 1812)) are two turtles species that are widely distributed and have ecological, ...
Seasonal activity and basking of the southernmost population of the freshwater turtle Phrynops hilarii (Chelidae)
(Brill Academic Publishers, 2017-03)
This study focuses on basking behaviour of Phrynops hilarii in the southernmost population of the species' range. The objective was to determine how environmental features affect the basking behaviour of the species. We ...

An adult female common snapping turtle (Chelydra serpentina) had a mass on the plantar surface of the right forelimb that was removed surgically. Microscopical examination revealed many spindle cells with mild anisocytosis ...
Mononuclear phagocytes in the blood of turtles characterized by ultrastructural and cytochemical analyses and by phagocytic activity
(Pergamon-Elsevier B.V. Ltd, 2008-12-01)
Ultrastructural and cytochemical characteristics of mononuclear phagocyte cells in turtles are not well described in the literature, especially in Phrynops hilarii. Thus, the aim of this study was to evaluate these ...
Pulmonary receptors in reptiles: discharge patterns of receptor populations in snakes versus turtles
(Springer, 2001-03-01)
This study examines the effects of lung inflation/deflation with and without CO2 on the entire population of pulmonary receptors in the vagus nerve in two species of snakes and two species of turtles. We asked the question, ...
Endocytic activity in the thrombocytes of the turtle Phrynopys hilarii (freshwater South American species)
(2000-10-01)
The phagocytic process in cells depends on lysosomal enzymes, high-energy metabolism and cellular recognition. In this paper, we investigated the presence of energy and recognition factors in thrombocytes of turtle Phrynopys ...
