To reach the objective of the 2008 national action plan for Martinique Island (French West Indies), the present paper examines horizontal and vertical movements in juveniles (n = 3) and adults life stages (11 females and 2 males) of 16 hawksbill turtles. Our results reveal the strong site fidelity of individuals to their foraging grounds (mean male foraging home range: 89.3 +/- 20.2km(2), mean female foraging home range: 336 +/- 284.7 km(2), mean juvenile foraging home range: 157.3 +/- 71.2 km(2)) and to the females' inter-nesting areas (mean home range: 284.2 +/- 523.7 km(2)). A spatial foraging overlap occurred between juveniles and males as they shared 41% of their 95% kernel foraging habitat. The turtles performed mainly long and shallow dives within the first 20 m deep around Martinique Island, occupying shallow waters close to shore. The migratory routes of the adult females revealed regional connectivity between the Caribbean islands, crossing 31 exclusive economic zones and international waters, and featuring distinct foraging grounds. This finding reinforces the significance of a cooperative network at the Caribbean scale to ensure the efficient conservation of this critically endangered species. specialized Eretmochelys imbricata Migration Diving behaviour Home range French Antilles Satellite tracking CARAIBES MER MARTINIQUE ANTILLES FRANCAISES 036 Biological Conservation 223 170-180 2018 0006-3207 https://www.documentation.ird.fr/hor/fdi:010073129 10.1016/j.biocon.2018.05.002 0006-3207 [F B010073129] https://www.documentation.ird.fr/hor/fdi:010073129 https://www.documentation.ird.fr/intranet/publi/2018/07/010073129.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2018-09-03 2023-07-11 fdi:010073129 fre
