Genetic characterization of the Critically Endangered hawksbill turtle (Eretmochelys imbricata) from the Mexican Pacific region

The hawksbill turtle (Eretmochelys imbricata) is a Critically Endangered species and has been a species of interest for decades. Only in recent years attention has been focused on the populations of the Eastern Pacific Ocean. We present a genetic characterization of this species in the Mexican Pacif...

Even with the small sample size reported here, our results show important relationships between the Mexican Pacific hawksbills and nesting populations of Central America and foraging areas along the Eastern and Indo-Pacific. These results, along with updated information on ecology and behavior, are essential for the future approach to conservation and management programs resulting in the recovery of this species in the Eastern Pacific.info:eu-repo/semantics/openAccessPontificia Universidad Católica de Valparaíso.
