Transferrin polymorphism in Amazon turtle (Podocnemis expansa) stocks [PDF]

Brazilian Journal of Genetics, 1996
The transferrin gene locus (Tf) was investigated in five populations of the Amazon turtle (Podocnemis expansa) sampled from five geographical areas in the Amazon region. This locus was polymorphic, showing three genotypes (Tfa Tfa, Tfa Tfb and Tfb Tfb), presumably encoded by two co-dominant alleles, Tfa and Tfb.

Parasitic Fauna of Free‐Living Chelonoidis denticulatus 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 ...

A systematic compendium of turtle mandibular anatomy using digital dissections of soft tissue and osteology

The Anatomical Record, Volume 306, Issue 6, Page 1228-1303, June 2023., 2023
Abstract Turtles are a charismatic reptile group with a peculiar body plan, which most notably includes the shell. Anatomists have often focused descriptive efforts on the shell and other strongly derived body parts, such as the akinetic skull, or the cervical vertebrae.

Sincronia entre o regime de vazante do rio e o comportamento de nidificação da tartaruga da Amazônia Podocnemis expansa (Testudinata: Pelomedusidae) [PDF]

Acta Amazonica, 1982
Resumo Há uma sincronização entre a vazante e o desencadeamento do comportamento de nidificação da tartaruga da Amazônia Podocnemis expansa. O comportamento de nidificação só começa quando o nível da água se estabiliza em seu nível mais baixo.

Community-Based Conservation and Management of Chelonians in the Amazon

Frontiers in Ecology and Evolution, 2022
Chelonians represent an important resource in the Amazon, either as a source of protein at the base of the food chain of aquatic and transition ecosystems, or in the dispersion of seeds of plants from floodplains and flooded forests.

Podocnemis expansa Turtles Hint to a Unifying Explanation for the Evolution of Temperature-Dependent Sex Determination in Long-Lived and Short-Lived Vertebrates

Sexual Development, 2021
The adaptive significance of temperature-dependent sex determination (TSD) remains elusive for many long-lived reptiles. Various hypotheses proposed potential ecological drivers of TSD.

Osteohistological characterization of notosuchian osteoderms: Evidence for an overlying thick leathery layer of skin

Journal of Morphology, Volume 284, Issue 1, January 2023., 2023
The perpendicular insertion of Sharpey's fibers in the external cortex suggests the presence of a thick leathery skin layer overlying notosuchian osteoderms. Although intramembranous ossification is the main process involved in the development of crocodyliform osteoderms, we reported a case of metaplastic development.
