Systematic Review on the Reproductive Aspects of the Chelidae Family
HydrobiologyThe Austro-American Side-necked Turtles originated in Gondwana and are found only in South America and Australasia. This paper aimed to review the reproductive aspects of the Chelidae family systematically.

Feeding habits of Mesoclemmys vanderhaegei (Testudines: Chelidae)
Acta Herpetologica, 2016 We studied the feeding habits of Mesoclemmys vanderhaegei in small water bodies in the central region of the Brazilian Cerrado. We captured 80 individuals, 79 of which [41 (52%) females, 27 males (34%), 11 (14%) juveniles] had stomach contents for ...

Characterization of innate immune activity in Phrynops geoffroanus (Testudines: Chelidae) [PDF]
Zoologia (Curitiba), 2009 The innate immune activity of the freshwater turtle Phrynops geoffroanus (Schweigger, 1812) was investigated, using a sheep-red-blood cell hemolysis assay.

Diet of Acanthochelys spixii and Hydromedusa tectifera (Chelidae) in the southern Brazil.
Caldasia, 2021 Data about the diet of the freshwater turtles Acanthochelys spixii and Hydromedusa tectifera from southern Brazil populations remain little known. In this context, the digestive tract of 21 A. spixii and 20 of H. tectifera individuals from

Does a lack of juveniles indicate a threat? Understanding body size distributions in a group of long-lived vertebrates. [PDF]
J Anim EcolWe used a large dataset to examine turtle size distributions and found that for most species in most areas, distributions are typically skewed towards large adults, with few juveniles present. Therefore, a lack of juveniles does not inherently indicate a declining population, and researchers should be cautious not to over‐interpret adult‐dominated ...

Functional and Character Disparity Are Decoupled in Turtle Mandibles. [PDF]
Ecol EvolHere, we compare functional disparity measured by biomechanical proxies and character disparity measured by discrete morphological characters in turtle jaws. Exploration of mandibular patterns reveals that several biomechanical configurations or character state combinations can lead to the same feeding type (i.e., convergence) or that high functional ...

Acid phosphatase in blood smears of Phrynops geoffroanus (Testudines: Chelidae) [PDF]
Revista Brasileira de Hematologia e Hemoterapia, 2011 Acid phosphatases belong to the hydrolases class of enzymes; they act on organic esters, releasing phosphate ions in acidic conditions. These enzymes are found in lysosomes and secretory vacuoles. They are important for tissue autolysis and proliferation and differentiation and cell transformation processes, but also indicate possible tumors ...
