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 ...

Lessons learned during a 12-year monitoring project with the endangered Magdalena River turtle (Podocnemis lewyana): hunting pressure, habitat degradation, and methodological considerations. [PDF]

Environ Monit Assess
Turtle species in the Family Podocnemididae, including the Colombian endemic and critically endangered Magdalena River Turtle Podocnemis lewyana, characteristically present low recapture rates that preclude estimation of population parameters using ...

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).

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 ...

To What Extent Can Life History Strategies Inform Reptile Conservation Planning? [PDF]

Ecol Evol
Conservation planners must effectively target interventions to reduce the extinction risk of species. If we can use a species' life history strategies to predict their responses to interventions, this offers a promising approach to better understand species extinction risks and conservation potential.

Immunolocalization of aromatase and estrogen and androgen receptors in the gonads and mesonephros of <i>Podocnemis expansa</i> during the first year of life. [PDF]

Anim Reprod
The endocrine regulation of testicular and ovarian development during early life in chelonians remains poorly understood, despite major morphophysiological changes occurring in this period.

Neuroanatomical study of the podocnemidid turtle Neochelys arenarum (Pleurodira), from the early Eocene of France. [PDF]

Anat Rec (Hoboken)
Abstract Neochelys is an exclusively European Eocene podocnemidid genus belonging to a linage that reached this continent at the early Eocene. The so far available anatomical information about it is relatively abundant, especially considering that of its shell, at least partially preserved for the eight valid species currently considered.

Variation and development of the turtle chondrocranium, with a description of the common musk turtle (Sternotherus odoratus, Kinosternidae, Cryptodira, Testudines). [PDF]

Anat Rec (Hoboken)
Abstract Based on histological cross‐sections, the chondrocranium of the common musk turtle (Sternotherus odoratus) was reconstructed, described, and compared with other turtles. It differs from that of other turtle chondrocrania by possessing elongated, slightly dorsally orientated nasal capsules with three dorsolateral foramina, which might be ...

Molecular detection of hemogregarines and haemosporidians in Brazilian free-living testudines

International Journal for Parasitology: Parasites and Wildlife, 2018
Morphological and molecular techniques were used to investigate the presence of hemogregarines and haemosporidians in biological samples of free-living Geoffroy's side-necked turtles (Phrynops geoffroanus) and Giant Amazon turtles (Podocnemis expansa ...

Community-based population recovery of overexploited Amazonian wildlife [PDF]

, 2017
The Amazon Basin experienced a pervasive process of resource overexploitation during the 20th-century, which induced severe population declines of many iconic vertebrate species.
