The western painted turtle genome, a model for the evolution of extreme physiological adaptations in a slowly evolving lineage
TLDR
Common vertebrate regulatory networks, some of which have analogs in human diseases, are often involved in the western painted turtle's extraordinary physiological capacities, and may offer important insights into the management of a number of human health disorders. Expand
Paternity in an Orinoco Population of Endangered Arrau River Turtles, Podocnemis expansa (Pleurodira; Podocnemididae), from Venezuela
TLDR
Genetic data from 7 microsatellite loci were used to determine the frequency of multiple paternity in clutches of giant Amazon river turtles, Podocnemis expansa, from the Orinoco River in Venezuela and found that a minimum of 10.3% could conclusively be shown to have been sired by more than one male. Expand
Population genetics of the endangered South American freshwater turtle, Podocnemis unifilis, inferred from microsatellite DNA data
TLDR
The results reveal a consistent pattern across multiple analyses, showing a clear subdivision between the populations inhabiting the Amazon and Orinoco drainages despite a direct connection via the Casiquiare corridor, and suggesting the existence of two biogeographically independent and widely divergent lineages. Expand
A Demographic Study of the Arrau Turtle (Podocnemis expansa) in the Middle Orinoco River, Venezuela
TLDR
It is concluded that additional efforts focused on protecting juveniles and adults of the arrau turtle, such as reinforcement of illegal hunting controls, must be implemented in order to ensure the success of the conservation program. Expand
Diet of peccaries (Tayassu tajacu and T. pecari) in a dry forest of Venezuela
TLDR
Results suggest that peccaries behave as frugivores and seed predators as most seed remains appeared cracked in the tropical dry forest of central Venezuela. Expand
Artificial incubation of yellow-headed sideneck turtle Podocnemis unifilis eggs to reduce losses to flooding and predation, Cojedes and Manapire Rivers, southern Venezuela
TLDR
Evaluated the hatch success of clutches transferred to artificial nest chambers at protected locations compared with natural clutches left in situ along stretches of the Cojedes and Manapire rivers (Venezuela). Expand
Divergent Sex-Specific Plasticity in Long-Lived Vertebrates with Contrasting Sexual Dimorphism
TLDR
Results ruled out the sex-specific plasticity hypotheses in P. expansa, indicating that differential plasticity does not favor males inherently, nor the larger sex, as would be expected if it was a pervasive driver of macroevolutionary patterns of sexual dimorphism across turtle lineages. Expand
Harvest of Endangered Sideneck River Turtles (Podocnemis spp.) in the Middle Orinoco, Venezuela
TLDR
Community-managed captive breeding of faster-maturing P. unifilis and P. vogli to satisfy turtle consumption needs may allow recovery of populations of P. expansa and make possible their legal subsistence harvest in the future. Expand
