Both physical and non-physical barriers can restrict gene flow among seabird populations. Understanding the relative importance of non-physical barriers, such as breeding phenology, is key to understanding seabird biodiversity. We investigated drivers of diversification in the Leach’s storm-petrel species complex (Hydrobates spp.) by examining population genetic structure across its range. Variation in the mitochondrial control region and six microsatellite loci was assayed in birds sampled from breeding colonies throughout the North Atlantic and North Pacific (H. leucorhoa leucorhoa), as well as from San Benito Islands (H. l. chapmani), and two seasonal populations in Guadalupe (summer breeding H. socorroensis and winter breeding H. cheimomnestes), Mexico. Weak but significant differentiation was found between populations of H. l. leucorhoa breeding in the Atlantic versus North Pacific, as well as between H. l. chapmani and H. l. leucorhoa, and between H. socorroensis and H. cheimomnestes within Guadalupe. ... : Leachs_stormpetrels_mitochondroalControlRegion_and_outgroupMitochondrial control region sequences for all Leach's storm-petrels used in our study (including from Hydrobates leucorhoa leucorhoa, H. l. chapmani, H. socorroensis, H. cheimomnestes, and outgroup sequences from H. castro).Leachs_stormpetrel_microsatellite_dataMicrosatellite data from all birds used in our study (including from H. leucorhoa leucorhoa, H. l. chapmani, H. socorroensis and H. cheimomnestes). ...
