Mixed-stock analysis reveals the migrations of juvenile hawksbill turtles (Eretmochelys imbricata) in the Caribbean Sea.
Hawksbill turtles (Eretmochelys imbricata) migrate between nesting beaches and feeding habitats that are often associated with tropical reefs, but it is uncertain which nesting colonies supply which feeding habitats. To address this gap in hawksbill biology, we compile previously published and new mitochondrial DNA (mtDNA) haplotype data for 10 nesting colonies (N = 347) in the western Atlantic...
متن کاملBlood gases, biochemistry and haematology of Galápagos hawksbill turtles (Eretmochelys imbricata)
The hawksbill turtle, Eretmochelys imbricata, is a marine chelonian with a circum-global distribution, but the species is critically endangered and has nearly vanished from the eastern Pacific. Although reference blood parameter intervals have been published for many chelonian species and populations, including nesting Atlantic hawksbills, no such baseline biochemical and blood gas values have ...
متن کاملGenetic Structure and Natal Origins of Immature Hawksbill Turtles (Eretmochelys imbricata) in Brazilian Waters
Understanding the connections between sea turtle populations is fundamental for their effective conservation. Brazil hosts important hawksbill feeding areas, but few studies have focused on how they connect with nesting populations in the Atlantic. Here, we (1) characterized mitochondrial DNA control region haplotypes of immature hawksbills feeding along the coast of Brazil (five areas ranging ...
متن کاملSpatial ecology of critically endangered hawksbill turtles Eretmochelys imbricata: implications for management and conservation
Elucidating spatio-temporal movements of animals is an integral component of wildlife conservation and protected species management. Between 2008 and 2010 we satellite tracked 15 adult female hawksbill turtles Eretmochelys imbricata in the eastern Pacific Ocean to evaluate their movement behavior and to guide management and conservation efforts of this highly endangered population. Movements an...
متن کاملGenetic Analysis to Elucidate the Natural History and Behavior of Hawksbill Turtles (Eretmochelys imbricata) in the Wider Caribbean: a Review and Re-Analysis
– Surveys of hawksbill turtles in the Atlantic Ocean have been undertaken to examine mitochondrial DNA (mtDNA) diversity and to test hypotheses concerning female reproductive migratory behavior and the composition of foraging ground populations. Studies of nesting females indicate that a natal homing mechanism predominates and that nesting populations should be considered separate stocks. Analy...
