简介
The green turtle Chelonia mydas is a circumglobal species that is susceptible to overexploitation as a food resource and incidental mortality in fisheries. Efforts to recover regional green turtle populations have been hampered by a lack of information on their biology. In particular, turtle movements and home ranges in neritic foraging habitats are not well understood. Thus, wildlife managers cannot accurately determine the habitat needs of green turtle populations. To address these understudied aspects, we carried out the first ever investigation of green turtle home range in neritic foraging habitats of the eastern Pacific Ocean. Twelve turtles, ranging from 50.9 to 82.5 cm in straight carapace length and from 17 to 70 kg in mass, were tracked with radio and sonic telemetry for 34 to 96 d at the Bahía de los Angeles foraging area in the Gulf of California, Mexico. Home range areas determined with minimum convex …
