title: Data from: Population genetics of four heavily exploited shark species around the Arabian Peninsula

description: The northwestern Indian Ocean harbors a number of larger marine vertebrate
 taxa that warrant the investigation of genetic population structure given
 remarkable spatial heterogeneity in biological characteristics such as
 distribution, behavior, and morphology. Here, we investigate the genetic
 population structure of four commercially exploited shark species with
 different biological characteristics (Carcharhinus limbatus, Carcharhinus
 sorrah, Rhizoprionodon acutus, and Sphyrna lewini) between the Red Sea and
 all other water bodies surrounding the Arabian Peninsula. To assess
 intraspecific patterns of connectivity, we constructed statistical
 parsimony networks among haplotypes and estimated (1) population
 structure; and (2) time of most recent population expansion, based on
 mitochondrial control region DNA and a total of 20 microsatellites. Our
 analysis indicates that, even in smaller, less vagile shark species, there
 are no contemporary barriers to gene flow across the study region, while
 historical events, for example, Pleistocene glacial cycles, may have
 affected connectivity in C. sorrah and R. acutus. A parsimony network
 analysis provided evidence that Arabian S. lewini may represent a
 population segment that is distinct from other known stocks in the Indian
 Ocean, raising a new layer of conservation concern. Our results call for
 urgent regional cooperation to ensure the sustainable exploitation of
 sharks in the Arabian region.
