Re-examination of population structure and phylogeography of hawksbill turtles in the wider Caribbean using longer mtDNA sequences.

Genetic Population Structure of Hawksbill Turtle (Eretmochelys imbricta) Using Microsatellite Analysis

Information on the genetic structure of marine species is essential for stock improvement programs. In orderto analyses the genetic diversity of the Hawksbill turtle (Eretmochelys imbricte) by the microsatellite geneticmethod, 64 samples were caught from the beaches located in Kish and Qeshm islands. Polymerase chainreactions (PCR) of genomic DNA extracted from the samples wer...

Genetic 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...

Conservation Status of Hawksbill Turtles in the Wider Caribbean, Western Atlantic and Eastern Pacific Regions

Population genetics and phylogeography of sea turtles.

The seven species of sea turtles occupy a diversity of niches, and have a history tracing back over 100 million years, yet all share basic life-history features, including exceptional navigation skills and periodic migrations from feeding to breeding habitats. Here, we review the biogeographic, behavioural, and ecological factors that shape the distribution of genetic diversity in sea turtles. ...

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...
