Sea turtles in the Mediterranean : Distribution, threats and conservation priorities
The Mediterranean Sea is a virtually enclosed basin that is frequented by three sea turtle species. In the last three decades the interest in sea turtles in the Mediterranean has continuouslyExpand
Migratory dichotomy and associated phenotypic variation in marine turtles revealed by satellite tracking and stable isotope analysis
This work uses variation in nitrogen stable isotope patterns between 2 foraging regions of loggerhead sea turtles Caretta caretta determined from samples of satellite-tracked indi- viduals to assign untracked turtles to a foraging region and investigates the relationship between fitness correlates and inferred migratory strategies.

The genetic structure of the loggerhead sea turtle (Caretta caretta) in the Mediterranean as revealed by nuclear and mitochondrial DNA and its conservation implications
Mitochondrial DNA data indicate that the female populations nesting on the islands of Crete and Cyprus have suffered a recent bottleneck or colonization event, but no bottleneck or founder effect was revealed by nuclear markers, thus indicating male-mediated gene flow from other populations that would increase nuclear genetic variability.

Population Structure of Loggerhead Turtles (Caretta caretta) in the Northwestern Atlantic Ocean and Mediterranean Sea
: To assess population genetic structure and evolutionary relationships among nesting populations of loggerhead turtles (Caretta caretta), we analyzed mitochondrial (mt) DNA variation in 113 samplesExpand
High frequency of multiple paternity in the largest rookery of Mediterranean loggerhead sea turtles
Investigating patterns of multiple paternity in clutches of loggerhead sea turtles in the largest Mediterranean rookery using four highly variable microsatellite loci suggests that polyandry is likely to increase effective population size compared to a population in which females would mate with only one male. Expand
Important areas at sea for adult loggerhead sea turtles in the Mediterranean Sea: satellite tracking corroborates findings from potentially biased sources
The concordance of tracking results with information from recoveries of flipper-tagged turtles suggests that the north Adriatic Sea and the Gulf of Gabès represent key areas for female adult Mediterranean loggerhead sea turtles. Expand
Metabolic heating in Mediterranean loggerhead sea turtle clutches
It is concluded that metabolic heating can be ignored in the estimate of hatchling sex ratios in Mediterranean loggerhead populations, and results provide the basis for a feasible monitoring of hatchedling sex ratio in the loggerhead sea turtle in the Mediterranean. Expand
Pivotal temperature for loggerhead turtles (Caretta caretta) from Kyparissia Bay, Greece
Comparison of incubation durations in the field with the pivotal durations obtained here suggest that hatchling sex ratio on some Mediterranean beaches is female biased but probably varies considerably within this region. Expand
Asynchrony between dietary and nutritional shifts during the ontogeny of green turtles (Chelonia mydas) in the Mediterranean
Overall evidence (gut contents analysis and stable isotope analysis) indicates that green turtles in the Mediterranean shift to a seagrass-based diet immediately after recruitment but turtle growth continues to rely on animal-derived nutrients for several years after recruitment. Expand
Mitochondrial DNA reveals Pleistocenic colonisation of the Mediterranean by loggerhead turtles (Caretta caretta)
The current genetic structure of C. caretta rookeries in the Mediterranean would be the result of at least two colonisation events from the Atlantic, the oldest one in Libya and a most recent in Calabria, combined with local extinctions during Pleistocenic glaciations and re-colonisations from glacial refugia in Libya, Eastern Turkey and Western Greece.
