Prevalence and parasitemia of Haemogregarina sp. in Podocnemis expansa (Testudines: Podocnemididae) from the Brazilian Amazon [PDF]

open access: yesBrazilian Journal of Veterinary Parasitology, 2015
Seventy-five turtles Podocnemis expansa in the Brazilian Amazon were examined for the presence of ectoparasites and hemoparasites. Samplings were performed in three study areas in the state of Tocantins, Brazil. Twenty-five specimens were sampled per study area (a commercial breeding facility, an indigenous subsistence breeding facility and a wild ...

Evolutionary insights in Amazonian turtles (Testudines, Podocnemididae): co-location of 5S rDNA and U2 snRNA and wide distribution of Tc1/Mariner [PDF]

open access: yesBiology Open, 2020
Eukaryotic genomes exhibit substantial accumulation of repetitive DNA sequences. These sequences can participate in chromosomal reorganization events and undergo molecular cooption to interfere with the function and evolution of genomes.

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]

open access: yesVet 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 ...

Prehatch Calls and Coordinated Birth in Turtles. [PDF]

open access: yesEcol Evol
The study investigates the phylogenetic distribution of within‐egg vocal behaviour among turtles and its role in synchronous hatching. Clutches from six turtle species with diverse ecological and reproductive niches were recorded, aiming to understand if asynchronous species vocalise from within the egg, the influence of clutch size on synchronous ...

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

open access: yesBrazilian 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.
