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

open access: yesThe 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.

Esofagotomia cervical em Tartaruga-da-Amazônia Podocnemis expansa Schweigger, 1812 (Testudines – Podocnemididae) [PDF]

open access: yesPubvet, 2016
This study proposes a technique of cervical esophagectomy Podocnemis expansa, an Amazonian river turtle aquatic habitat. The animals belonging to the Research Laboratory of Wild Animals FAMEV-UFU, were anesthetized with propofol at a dose of 10mg/Kg/IV.

A large phylogeny of turtles (Testudines) using molecular data [PDF]

open access: yes, 2012
Turtles (Testudines) form a monophyletic group with a highly distinctive body plan. The taxonomy and phylogeny of turtles are still under discussion, at least for some clades. Whereas in most previous studies, only a few species or genera were considered,

Análisis de una estrategia de conservación para Podocnemis unifilis en la Estación de Biodiversidad Tiputini [PDF]

open access: yes, 2010
Podocnemis unifilis has experienced a drastic decrease along its distribution in the Ecuadorian Amazon. With this motivation the Tiputini Biodiversity Station from Universidad San Francisco de Quito began a head-starting project for this species ...

Pivotal temperature and sexual dimorphism of Podocnemis expansa hatchlings (Testudines: Podocnemididae) from Bananal Island, Brazil

open access: yesZoologia (Curitiba), 2009
A common problem when trying to identify the sex of hatchling turtles is that juveniles are not obviously externally dimorphic and current techniques to identify sex are often invasive.

Population dynamics and biological feasibility of sustainable harvesting as a conservation strategy for tropical and temperate freshwater turtles.

open access: yesPLoS ONE, 2020
BACKGROUND:Conservation strategies are urgently needed for tropical turtles that are increasingly threatened by unsustainable exploitation. Studies conducted exclusively in temperate zones have revealed that typical turtle life history traits (including ...
