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 ...

Yeasts Occurring in Surface and Mouth Cavity of Two Chelonian Species, Podocnemis expansa Schweigger and P. unifilis Troschel (Reptilia: Chelonia: Pelomedusidae), in the Javaés River Border of Araguaia National Park in Brazil [PDF]

International Journal of Microbiology, 2010
Thirty-eight specimens of free-ranging Podocnemis expansa (Amazon turtle) and 22 of P. unifilis (Tracajá) were screened for yeast isolation from surface (plastron, skin, and nails), eye, and mouth cavity.

Prehatch Calls and Coordinated Birth in Turtles. [PDF]

Ecol 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 ...

Trends in Urban Wild Meat Trade of Chelonians (Turtles and Tortoises) in the Peruvian Amazon [PDF]

Animals
Culturally, chelonians are important sources of nutrition and income for rural and urban people in tropical rainforests, but urban trade can cause declines in wild populations.

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 ...

Shell Constraints on Evolutionary Body Size-Limb Size Allometry Can Explain Morphological Conservatism in the Turtle Body Plan. [PDF]

Ecol Evol
Turtle body size and limb size scale nearly isometrically along the group's evolution, although major deviations are only seen in highly specialized ecological or morphological groups. The evolution of the shell constrained turtle body proportions, as they show lower rates of variance accumulation in these allometries than other more diverse and ...

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

Biology 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.
