Dramatic local population decline brought about by anthropogenic-driven change is an increasingly common threat to biodiversity. Seabird life history traits that make them particularly vulnerable to such change, therefore understanding population connectivity and dispersal dynamics is vital for successful management. Our study used a 360 base-pair mitochondrial control region locus sequenced for 103 individuals and 18 nuclear microsatellite loci genotyped for 245 individuals to investigate population structure in the Atlantic and Pacific populations of the pelagic seabird, Leach’s storm-petrel Oceanodroma leucorhoa leucorhoa. This species is under intense predation pressure at one regionally important colony on St Kilda, Scotland, where a disparity between population decline and predation rates hints at immigration from other large colonies. AMOVA, FST, ΦST and Bayesian cluster analyses revealed no genetic structure among Atlantic colonies (Global ΦST = -0.02 P >0.05, Global FST = 0.003, P>0.05, STRUCTURE K = 1), consistent with either contemporary gene flow or strong historical association within the ocean basin.
