Marine turtle genetics program

The genetics archive, the genetics laboratory, and the database operated by our group provide the infrastructure necessary to drive the management science and ensure high-quality data for current and future needs. We also develop new molecular techniques and innovative analytical approaches designed specifically to improve capacity to define stock structure and identify management units MUs for conservation. The Marine Turtle Genetics Program supports and coordinates regional studies of sea turtle stock structure to ensure that datasets can be combined.

We collaborate with numerous research groups in the U. The Marine Turtle Genetics Program has previously had great success establishing and updating rookery databases that are available to the broader research community for both loggerhead turtles see Shamblin et al.

The population genetics of hawksbill turtles in the Persian Gulf have been summarized in Table 14 due to contradictory results that may be the result of different methodologies among studies. The importance of understanding genetic diversity among nesting populations has been reviewed by FitzSimmons and Limpus The use of microsatellite markers to understand paternity and mating systems in sea turtles is reviewed by Jensen et al.
