Geological control of Podocnemis expansa and Podocnemis unifilis nesting areas in Rio Javaés, Bananal Island, Brazil Controle geológico das áreas de nidificação de Podocnemis expansa e Podocnemis unifilis no Rio Javaés, Ilha do Bananal, Brasil [PDF]

Acta Amazonica, 2003
The distribution of the nests of Podocnemis expansa (Amazon turtle) and Podocnemis unifilis (yellow-spotted side neck turtle) along the point bars of the Javaés River in Bananal Island, demonstrates a clear preference of these chelonians for ...

Cytogenetic comparison of Podocnemis expansa and Podocnemis unifilis: a case of inversion and duplication involving constitutive heterochromatin [PDF]

Genetics and Molecular Biology, 2013
Podocnemis expansa and P. unifilis present 2n = 28 chromosomes, a diploid number similar to those observed in other species of the genus. The aim of this study was to characterize these two species using conventional staining and differential CBG-, GTG ...

Parasitic Fauna of Free-Living <i>Chelonoidis denticulatus</i> From the Rio Acre Ecological Station and the Municipality of Cruzeiro do Sul, Western Amazon, Brazil. [PDF]

Vet Med Int
Tortoises, such as Chelonoidis denticulatus, are described as hosts of many parasites, such as helminths and ticks of the genus Amblyomma, which are important vectors of rickettsial infection in Brazil. Additionally, the high consumption of meat from these animals in Acre results in a high risk of zoonotic outbreaks due to contact with the hosts and ...

Socioeconomic drivers of wild meat consumption in the city of Iquitos, Peru. [PDF]

Conserv Biol
Abstract Wild meat represents a vital source of micro‐ and macronutrients for forest‐dwelling people; however, city dwellers with access to animal protein from different animals may also consume large amounts of wild meat as part of their customs and traditions, to diversify their diets, to maintain connections to their rural kin, and to access meat ...

New insights of karyoevolution in the Amazonian turtles Podocnemis expansa and Podocnemis unifilis (Testudines, Podocnemidae) [PDF]

Molecular Cytogenetics, 2016
Cytogenetic studies were conducted in the Brazilian Amazon turtles, Podocnemis expansa Schweigger, 1912 (PEX) and Podocnemis unifilis Troschel, 1848 (PUN) to understand their karyoevolution. Their chromosomal complements were compared using banding techniques (C, G-, Ag-NOR and Chromomycin A3) and fluorescence in situ hybridization (FISH), and efforts ...

Shell characterization of the youngest valid species of the European Eocene genus Neochelys (Pleurodira, Podocnemididae): The Spanish Bartonian Neochelys salmanticensis. [PDF]

Anat Rec (Hoboken)
Abstract The freshwater pleurodiran turtle Neochelys is the best‐represented member of Podocnemididae in the European record, being known by eight Eocene species. The youngest of them is the Bartonian (middle Eocene) Neochelys salmanticensis, from the Duero Basin (Salamanca Province, Central Spain).
