Biodiversity loss has accelerated over the last decade, driven by the impact of global warming, alteration of habitats and the dispersal of invasive exotic species due to human action. The reintroduction of captive-bred animals is one of the potential solutions to cope with this problem. A study led by the experts Marta Pascual and Carlos Carreras, members of the Laboratory of Evolutionary Genetics of the Faculty of Biology and the Biodiversity Research Institute of the University of Barcelona (IRBio), analyzed the impact of a green turtle reintroduction program that began 50 years ago in the Cayman Islands.
