The influence of season, environment, sex, and body mass on biochemical profile of the freshwater turtle Phrynops geoffroanus (Schweigger, 1812)

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2022
We analyzed the influence of the season, the environment, and the sex, as well as the relation of body mass (BM) in the serum albumin (ALB), aspartate aminotransferase (AST), creatinine (C), creatine kinase (CK), phosphorus (P), total calcium (tCa ...

Morphological Changes of the Epididymis and Description of the Excurrent Ducts of Phrynops geoffroanus (Testudines: Chelidae) During the Reproductive Cycle [PDF]

The Anatomical Record, 2010
AbstractThe seminal ducts (efferent ductule, epididymis, and deferent duct) in adults of Phrynops geoffroanus were examined using light microscopy. A series of tubules (efferent ductules) connect the testes to the epididymides. The efferent ductules are formed by a rete of small tubules of varying diameters, with simple columnar epithelium formed by ...

Spatial and Temporal Variation in the Occurrence and Abundance of the Freshwater Turtles in Water Bodies of a Peri-Urban Area in the Midwestern Brazil

Acta Herpetologica
In this study we evaluated spatial and temporal variations in the occurrence and abundance of freshwater turtles in four water bodies located in the headwaters of a stream in the peri-urban area of Campo Grande, Mato Grosso do Sul, Midwestern Brazil ...

Anestesia de cágado-de-barbicha Phrynops geoffroanus Schweigger, 1812 (Testudines) com a associação midazolan e propofol - DOI: 10.4025/actascibiolsci.v31i3.674

Acta Scientiarum: Biological Sciences, 2009
Os cágados apresentam fisiologia e morfologia únicas, que se diferenciam em muitos aspectos dos mamíferos. Por isso, a monitoração do paciente durante um processo anestésico ou sedativo deve ser realizada, porque dosagens e drogas com resultados ...

First record of biogenic silica in the stomach content of freshwater turtles

Acta Herpetologica
Aquatic species such as fish and turtles consume sponges and plants, which are sources of biogenic silica. Sponges belong to the phylum Porifera, and species in the class Demospongiae produce siliceous spicules, while plants form phytoliths. Some turtle

The topological organization of the turtle cranium is constrained and conserved over long evolutionary timescales

The Anatomical Record, Volume 307, Issue 8, Page 2713-2748, August 2024.
Abstract The cranium of turtles (Testudines) is characterized by the secondary reduction of temporal fenestrae and loss of cranial joints (i.e., characteristics of anapsid, akinetic skulls). Evolution and ontogeny of the turtle cranium are associated with shape changes.

Ecological aspects of a population of Phrynops geoffroanus (Schweigger, 1812) in a semi-arid area of Northeastern Brazil

Research, Society and Development, 2021
Phrynops geoffroanus is a testudine of the family Chelidae that has a wide distribution. However, there are gaps in the knowledge of its biology. This study aimed to characterize demographically and morphometrically a population of Phrynops geoffroanus in an ephemeral water reservoir in a semi-arid area of Paraíba, in the period from April 2016 to ...

Oral bacterial microbiota and traumatic injuries of free-ranging Phrynops geoffroanus (Testudines, Chelidae) in southeastern Brazil [PDF]

Phyllomedusa: Journal of Herpetology, 2009
During 2006 and 2007, we collected free-ranging Phrynops geoffroanus, from two anthropogenically altered rivers in southeastern Brazil. Oral microbiological samples were taken for isolation of aerobic and facultative anaerobic bacteria; a physical ...
