Prehatch Calls and Coordinated Birth in Turtles. [PDF]

Ecol Evol
The study investigates the phylogenetic distribution of within‐egg vocal behaviour among turtles and its role in synchronous hatching. Clutches from six turtle species with diverse ecological and reproductive niches were recorded, aiming to understand if asynchronous species vocalise from within the egg, the influence of clutch size on synchronous ...

Shell Constraints on Evolutionary Body Size-Limb Size Allometry Can Explain Morphological Conservatism in the Turtle Body Plan. [PDF]

Ecol Evol
Turtle body size and limb size scale nearly isometrically along the group's evolution, although major deviations are only seen in highly specialized ecological or morphological groups. The evolution of the shell constrained turtle body proportions, as they show lower rates of variance accumulation in these allometries than other more diverse and ...

Cytogenetic studies in Podocnemis expansa and Podocnemis sextuberculata (Testudines, Podocnemididae), turtles of the Brazilian Amazon [PDF]

Caryologia, 2011
Cytogenetic studies were conducted with Podocnemis expansa and Podocnemis sextuberculata, tur- tles of the Brazilian Amazon, aimed at a better characterization of the chromosomes of these species. To obtain mitotic chromosomes, lymphocytes were grown in a culture medium for karyotypes (RPMI), and harvested cells were treated to obtain metaphase ...

Int J Microbiol, 2010
Thirty-eight specimens of free-ranging Podocnemis expansa (Amazon turtle) and 22 of P. unifilis (Tracajá) were screened for yeast isolation from surface (plastron, skin, and nails), eye, and mouth cavity.

Physical Characteristics of Giant Amazon Turtle (Podocnemis expansa) Nests

Chelonian Conservation and Biology, 2007
ABSTRACT We determined the relationship between incubation success and physical characteristics of Podocnemis expansa nests on 4 sand beaches of the Araguaia River in the southern Amazon basin, Brazil. Sand samples measuring grain size, humidity, and density were collected during the first 7 days after egg laying.
