Population genetics analysis of Podocnemis sextuberculata (Testudines, Podocnemidae): Lack of population structure in the central Amazon Basin
The chelonians are, in general, important for the economy of the traditional populations of the Amazon region, especially as a source of animal protein. Furthermore, sub-products, such as eggs and fat, are utilized in the manufacture of cosmetics, and the plastron and carapace are used in the manufa...

The levels of genetic variability observed were homogeneous among the sampling localities. These results (O{middle tilde} ST and Nm) are compatible with what is known about the ecology of this species, which has a great migratory capacity. © FUNPEC-RP. 2020-05-07T14:00:26Z 2020-05-07T14:00:26Z 2011 Artigo https://repositorio.inpa.gov.br/handle/1/14999 10.4238/vol10-3gmr1163 en Volume 10, Número 3, Pags. 1393-1402 Attribution-NonCommercial-NoDerivs 3.0 Brazil http://creativecommons.org/licenses/by-nc-nd/3.0/br/ application/pdf Genetics and Molecular Research |
