  abstract = {{T}he blue shark {P}rionace glauca is a top predator with one of the widest geographical distributions of any shark species. {I}t is classified as {C}ritically {E}ndangered in the {M}editerranean {S}ea, and {N}ear {T}hreatened globally. {P}revious genetic studies did not reject the null hypothesis of a single global population. {T}he blue shark was proposed as a possible archetype of the "grey zone of population differentiation," coined to designate cases where population structure may be too recent or too faint to be detected using a limited set of markers. {H}ere, blue shark samples collected throughout its global range were sequenced using a specific {RAD} method ({DA}r{T}seq), which recovered 37,655 genome-wide single nucleotide polymorphisms ({SNP}s). {T}wo main groups emerged, with {M}editerranean {S}ea and northern {A}tlantic samples ({N}orthern population) differentiated significantly from the {I}ndo-west {P}acific samples ({S}outhern population). {S}ignificant pairwise {F}-{ST} values indicated further genetic differentiation within the {A}tlantic {O}cean, and between the {A}tlantic {O}cean and the {M}editerranean {S}ea. {R}econstruction of recent demographic history suggested divergence between {N}orthern and {S}outhern populations occurred about 500 generations ago and revealed a drastic reduction in effective population size from a large ancestral population. {O}ur results illustrate the power of genome scans to detect population structure and reconstruct demographic history in highly migratory marine species. {G}iven that the management plans of the blue shark (targeted or bycatch) fisheries currently assume panmictic regional stocks, we strongly recommend that the results presented here be considered in future stock assessments and conservation strategies.},
