The aim of the present study was to investigate the reproductive behavior of the giant
Amazon River turtle (Podocnemis expansa) in the Amazon. This was carried out by …

Abstract The giant South American river turtle (Podocnemis expansa) is the largest extant
member of the suborder Pleurodira and the largest freshwater chelonian in South America …

The genus Podocnemis comprises six living species, including P. erythrocephala (irapuca-
red-headed river turtle). Data are available concerning the reproductive biology of the …

We used eight microsatellite loci to investigate the mating system in P. unifilis. DNA samples
were collected from 66 hatchlings sampled from six nests on a central Amazon River beach …

Sea turtles exhibit highly migratory behavior and spend most of their life in oceanic habitats,
complicating the study of their biology and creating gaps in our knowledge regarding their …

Genetic studies of multiple paternity are a valuable tool to gain information on the
reproductive biology of turtles. We analyzed paternity type in Podocnemis sextuberculata …

The incidence of multiple paternities in two populations of Podocnemis expansa of Brazilian
Amazon both rose in captivity and in natural habitat, was verified by using five microsatellite …

We used genetic data from 7 microsatellite loci to determine the frequency of multiple
paternity in clutches of giant Amazon river turtles, Podocnemis expansa, from the Orinoco …

Genetic analyses of nuclear DNA (eg, microsatellites) are a primary tool for investigating
mating systems in reptiles, particularly marine turtles. Whereas studies over the past two …

Hybridization between sea turtle species occurs with particularly high frequency at two
adjacent nesting areas in northeastern Brazil. To understand the outcomes of hybridization …
