Hawksbill turtles move between nesting colonies and feeding grounds, but in most cases it is not known which reproductive populations occupy a particular feeding habitat. In this study, genetic markers derived from mitochondrial DNA sequences are used to estimate the contribution of Caribbean nesting colonies to a feeding ground at Mona Island, Puerto Rico (n = 41). Maximum likelihood analysis indicates that this feeding population is not composed primarily of turtles from the neighboring nesting colony (also on Mona Island), but is drawn from nesting populations throughout the Caribbean region. A sampled nesting colony in the southern hemisphere (Bahia, Brazil) did not contribute, at detectable levels, to the Mona Island feeding ground. From this evidence, we concluded that hawksbill turtles recruit to feeding grounds over a scale of hundreds of kilometres, but not over the scale of 7000 km that separate Mona Island from Bahia, Brazil. These data indicate that a hawksbill turtle harvest on feeding grounds will reduce nesting populations throughout the Caribbean region.

Histología gonadal y criterios fenotípicos de maduración en las tortugas marinas Chelonia mydas y Eretmochelys imbricata (Testudines: Chelonidae) de Cuba

“…Otros agregados marinos de esta especie en el Caribe (Diez & van Dam 2002, Chacón 2004 y Australia (Limpus 1992, Limpus & Miller 2008) también presentan mezcla de estos estados ontogenéticos, los cuales tienden a ser genéticamente heterogéneos (Bass 1999, Bowen et al 1996, Díaz-Fernández et al 1999. Si utilizamos las ecuaciones de regresión lineal entre el LRC y el LCC (C. mydas: LRC = (0.94 x LCC) + 0.5cm; E. imbricata: LRC = (0.84 x LCC) + 7.63cm) que Lee (2009) determinó para ambas especies en el agregado marino del Archipiélago Jardines del Rey, obtenemos para las hembras prepubescentes de C. mydas y E. imbricata intervalos de LCC de 68.6-98.4cm y 50.4-77.8cm respectivamente.…”

A New Approach to Mixed Stock Analysis that Informs on the Management and Conservation of Hawksbill in the Wider Caribbean: the Case of the Legal Fishery in Jardines del Rey, Cuba

“…In these species, once sexual maturity is reached turtles begin periodic migrations between feeding and breeding/nesting areas, which are sometimes separated by thousands of kilometers (Miller, 1997), with females (Carr, 1967), and to a lesser extent males , exhibiting phylopatric or "natal homing" behavior. This has been verified using flipper tags (Limpus et al, 1992;Horrocks et al, 2011), satellite tracking (Luschi et al, 2006;Godley et al, 2010) and mtDNA markers Bowen et al, 1996), in which has demonstrated significant differences in the mtDNA haplotype frequencies among nesting populations (Bowen and The Wider Caribbean has also been the scene of political conflict in the management of E. imbricata. The majority of WC nations had already abandoned the legal fishery for this species when Cuba permanently closed its legal fishery in January 2008.…”

Genetic characterization of eastern Atlantic hawksbill turtles at a foraging group indicates major undiscovered nesting populations in the region

“…To assure broad comparisons of our results with previous studies, our control region sequence alignment was trimmed to 384 bp of length. Haplotype designation followed that from previous publications Bowen et al, 1996Bowen et al, , 2007bDíaz-Fernández et al, 1999;Browne et al, in press). Deletion in haplotype D at position 59 and a 10-bp insertion at position 354 in haplotype MX1A were treated as single substitutions following Bowen et al (2007b).…”
