Origin and dispersal routes of foreign green and Kemp's ridley turtles in Spanish Atlantic and Mediterranean waters

摘要: The presence of the green and Kemp's ridley turtles is rare at Atlantic Mediterranean Spanish waters, but records have increased during last decades. We reported a new set reviewed all historical observations these species. analysis mitochondrial DNA fragment newest provided insights about origin individuals. arrived from western nesting beaches, although discovering haplotype suggested existence an unknown or low sampled area origin. Furthermore, genetic was crucial for species identification in one specimen, hence recommending use markers to confirm All presented haplotypes exclusive beaches concentrated African populations. Thus, closest eastern areas were discarded as source populations migration route this described.
