UCLA study of threatened desert tortoises offers new conservation strategy
23hA UCLA study publishing Nov. 27 in Science supports a new conservation strategy. Climate change increasingly makes relocating threatened species necessary, despite the frequently low success rate. The study found tortoises with lots of genetic variation were much more likely to survive after their relocation. The research supports this fast, inexpensive conservation tool, and upends the convention
