Mirroring-in nature? Comparison of kinship analysis in clutches of the endangered giant Amazon River turtle, Podocnemis expansa (Chelonia: Podocnemididae) in both captivity and natural habitat

ABSTRACT 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 loci. Three hundred twenty-seven offspring from two different sampling sites were genotyped. The analys...
