bearing an orphaned haplotype (Dc_A2) for leatherbacks. This haplotype was considered an orphaned haplotype because no match with nesting population were
found at that moment. In a later comprehensive genetic analysis of worldwide stock
structure, it was ascertained that the origins of the orphaned haplotype came from
Gabon and/ or Western Africa (Dutton et al. 2013).
Later, Vargas et al. (2013) reanalyzed samples from a previous study and estimated the contribution of source rookeries to a Brazilian feeding ground, using
population genetic measures and mixed stock analysis MSA, including two previously genetic undescribed rookeries: Gabon and Guadalupe/Martinique. Results of
the MSA indicated major contribution to the Brazilian pelagic aggregate from
Gabon (78%), the largest population of leatherbacks in the world.
