High Early Embryo Mortality and Low Hatching Success Observed in Aldabra Giant Tortoise Populations

Ecology and Evolution, Volume 16, Issue 7, July 2026.
This preliminary study provides the first population‐level assessment of fertilisation and hatching success in the Aldabra giant tortoise across natural and translocated populations in Seychelles, revealing low and highly variable hatching success—particularly in translocated populations.

Pliocene chelonian fossil eggs from Gran Canaria, Canary Islands

, 1987
Thirty years ago Macau-Vilar (1958) reported chelonian eggs from Gran Canaria. Analysis of the microstructure of these eggs corroborates this identification. Field studies show that these eggs, which were originally thought to be Miocene in age, are from

CT Anatomy of the Lower Respiratory Tracts of the Testudo graeca

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
In this study, we used high‐resolution computed tomography (CT) to examine the trachea, bronchi and lungs of Testudo graeca. The tortoises were scanned in two different body positions: When their head, neck and limbs were retracted inside the shell (flexed), and when these body parts were extended outside the shell.

Turtles and tortoises of Togo : historical data, distribution, ecology, and conservation

, 2014
The chelonian fauna of Togo (West Africa) has been scarcely studied to date. In this article, we review and summarize all available data on the distribution, ecology, and conservation status of the chelonian species of Togo and present a short historical

A Multispecies Systematic and Critical Review of Intranasal Administration in Veterinary Anaesthesia and Emergency Care: Promising Evidence and Overlooked Challenges

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
This review evaluates the clinical potential and limitations of intranasal (IN) drug administration in veterinary anaesthesia and emergency care. IN delivery can provide clinically relevant sedation, analgesia and drug reversal, but its success is not universally reliable and is strongly influenced by species‐specific anatomy, formulation ...

Radiographic anatomy aspects and gastrointestinal transit time in Podocnemis unifilis troschel, 1848 (Testudines, Podocnemididae). = Aspectos anátomo-radiográficos e tempo de trânsito gastrintestinal em Podocnemis unifilis troschel, 1848 (Testudines, Podocnemididae)

Acta Scientiarum: Biological Sciences, 2010
The present study analyzed the radiographic anatomy and determined thegastrointestinal transit time of Podocnemis unifilis. We used ten animals belonging to LAPAS from the Federal University of Uberlândia, Uberlândia, Minas Gerais State, Brazil.

Mid‐Domain Effect and Wooded Habitat Shape Mediterranean Reptile Communities

Biological Diversity, Volume 3, Issue 2, Page 65-82, June 2026.
Analyzing a large number of reptiles observed across protected areas in Central Italy, we tested whether the mid‐domain effect explains hump‐shaped richness–elevation patterns. Species richness was best predicted by the combined influence of geometric constraints and woodland cover, revealing two contrasting species clusters and offering a robust ...
