Lacking conservation genomics in the giant Galápagos tortoise
Peer Community Journal, 2021 Conservation policy in the giant Galpagos tortoise, an iconic endangered animal, has been assisted by genetic markers for 15 years: a dozen loci have been used to delineate thirteen (sub)species, between which hybridization is prevented.

Predation impact on threatened spur-thighed tortoises by golden eagles when main prey is scarce
Scientific Reports, 2022 A reduction in adult survival in long-living species may compromise population growth rates. The spur-thighed tortoise (Testudo graeca) is a long-lived reptile that is threatened by habitat loss and fragmentation. Golden eagles (Aquila chrysaetos), whose

Linear and landscape disturbances alter Mojave desert tortoise movement behavior
Frontiers in Ecology and Evolution, 2023 IntroductionAnimal movements are influenced by landscape features; disturbances to the landscape can alter movements, dispersal, and ultimately connectivity among populations.

Turtles and Tortoises Are in Trouble [PDF]
Current Biology, 2020 Turtles and tortoises (chelonians) have been integral components of global ecosystems for about 220 million years and have played important roles in human culture for at least 400,000 years. The chelonian shell is a remarkable evolutionary adaptation, facilitating success in terrestrial, freshwater and marine ecosystems.

Clade‐wide morphological and functional variation of the sauropsid columella
The Anatomical Record, EarlyView.Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

Sex‐Biased Interactions Between Spur‐Thighed Tortoises (Testudo graeca) and Hindgut Nematodes [PDF]
Ecol EvolTortoise (Testudo graeca) responses to nematode infestation are clearly sex‐biased, where females seem more resilient to nematode infestation than males. These findings emphasizes the need for sex‐directed conservation approaches in tortoises. ABSTRACT The nature of endosymbiont interactions is driven by different ecological and evolutionary processes.

Emerging Infectious Diseases, 2011 “The men of old were born like the wild beasts. In woods, caves, and groves, they lived on food gathered in the fields,” wrote Marcus Vitruvius Pollio more than 2,000 years ago in his well-known account of classical traditions in architecture. One day, a dense group of trees, agitated by winds and storms, caught fire.
