Synopsis of the story -

Widespread wildlife trafficking is putting beautiful species of tortoise from Madagascar at risk of extinction.

Radiated tortoises are trafficked for sale as pets, a food delicacy or use of their shells in decor. Historically an estimated 12 million individual radiated tortoises once roamed much of the spiny forests of Madagascar. Today, less than 1.5 million remain and populations continue to rapidly decline.

 There are about 25,000 radiated tortoises recovered from illegal trade living at centers for the nonprofit Turtle Survival Alliance in Southern Madagascar (pictured.)

 The Saint Louis Zoo Institute for Conservation Medicine and Saint Louis Zoo WildCare Institute Center for Chelonian Conservation both support efforts to protect this species. Read more about the risks facing radiated tortoises and what you can do to help from members of the Radiated Tortoise Veterinary Working Group

Climate change and sex determination of Galapagos tortoises

Enjoy this blog on Sex ratios, climate change, and giant tortoises by Dr. Patrick Moldowan. Patrick provides a great review of the paper by Deem et al (2023) published earlier this year. In the paper, we investigated the roles of nest location and temperature in influencing the sex of hatchling tortoises. The findings from this study offer important information for the conservation of giant tortoises, among other species with temperature sex determination (TSD), in our changing world.
