Seascape Genomics of the Smooth Hammerhead Shark Reveals Regional Adaptive Clinal Variation.

Globally, hammerhead sharks have experienced severe declines owing to continued overexploitation and anthropogenic change. The smooth hammerhead shark remains understudied compared to other members of the family Sphyrnidae. Despite its vulnerable status, a comprehensive understanding of its genetic landscape remains lacking in many regions worldwide.

Local adaptation with gene flow in a highly dispersive shark.

Adaptive divergence in response to environmental clines are expected to be common in species occupying heterogeneous environments. Despite numerous advances in techniques appropriate for non-model species, gene-environment association studies in elasmobranchs are still scarce. The bronze whaler or copper shark () is a large coastal shark with a wide distribution and one of the most exploited elasmobranchs in southern Africa.

Species identification and comparative population genetics of four coastal houndsharks based on novel NGS-mined microsatellites.

The common smooth-hound () is the topmost bio-economically and recreationally important shark species in southern Africa, western Africa, and Mediterranean Sea. Here, we used the Illumina HiSeq™ 2000 next-generation sequencing (NGS) technology to develop novel microsatellite markers for . Two microsatellite multiplex panels were constructed from 11 polymorphic loci and characterized in two populations of representative of its South African distribution.
