Data from: Hybridization of Southern Hemisphere blue whale subspecies and a sympatric area off Antarctica: impacts of whaling or climate change?

Understanding the degree of genetic exchange between subspecies and populations is vital for the appropriate management of endangered species. Blue whales (Balaenoptera musculus) have two recognized Southern Hemisphere subspecies that show differences in geographic distribution, morphology, vocalizations and genetics. During the austral summer feeding season the pygmy blue whale (B. m. brevicauda) is found in temperate waters and the Antarctic blue whale (B. m. intermedia) in polar waters. Here we used genetic analyses to report...

Data from: Targeted multiplex next-generation sequencing: Advances in techniques of mitochondrial and nuclear DNA sequencing for population genomics

Brittany Hancock-Hanser, Amy Frey, Matthew S. Leslie, Peter H. Dutton, Frederick I. Archer, Phillip A. Morin & Brittany L. Hancock-Hanser
Next-generation sequencing (NGS) is emerging as an efficient and cost-effective tool in population genomic analyses of nonmodel organisms, allowing simultaneous resequencing of many regions of multi-genomic DNA from multiplexed samples. Here, we detail our synthesis of protocols for targeted resequencing of mitochondrial and nuclear loci by generating indexed genomic libraries for multiplexing up to 100 individuals in a single sequencing pool, and then enriching the pooled library using custom DNA capture arrays. Our use of...

Data from: Circumpolar diversity and geographic differentiation of mtDNA in the critically endangered Antarctic blue whale (Balaenoptera musculus intermedia)

Angela L. Sremba, Brittany Hancock-Hanser, Trevor A. Branch, Rick L. LeDuc & C. Scott Baker
The Antarctic blue whale (Balaenoptera musculus intermedia) was hunted to near extinction between 1904 and 1972, declining from an estimated initial abundance of more than 250,000 to fewer than 400. Here, we describe mtDNA control region diversity and geographic differentiation in the surviving population of the Antarctic blue whale, using 218 biopsy samples collected under the auspices of the International Whaling Commission (IWC) during research cruises from 1990–2009. Microsatellite genotypes and mtDNA sequences identified 166...

Data from: Comparative population genetic analysis of bocaccio rockfish Sebastes paucispinis using anonymous and gene-associated simple sequence repeat loci

Vincent P. Buonaccorsi, Carol A. Kimbrell, Eric A. Lynn & John R. Hyde
Comparative population genetic analyses of traditional and emergent molecular markers aid in determining appropriate use of new technologies. The bocaccio rockfish Sebastes paucispinis is a high-gene-flow marine species off the west coast of North America that experienced strong population decline over the past three decades. We used 18 anonymous and 13 gene associated simple sequence repeat loci (EST-SSRs) to characterize range-wide population structure with temporal replicates. No FST-outliers were detected using the LOSITAN program, suggesting...

Data from: Influences of past climatic changes on historical population structure and demography of a cosmopolitan marine predator, the common dolphin (genus Delphinus)

Ana Amaral, Luciano Beheregaray, Kerstin Bilgmann, Luís Freitas, Kelly Robertson, Marina Sequeira, Karen Stockin, M. M. Coelho & Luciana Möller
Climatic oscillations during the Pleistocene have greatly influenced the distribution and connectivity of many organisms, leading to extinctions but also generating biodiversity. While the effects of such changes have been extensively studied in the terrestrial environment, studies focusing on the marine realm are still scarce. Here we used sequence data from one mitochondrial and five nuclear loci to assess the potential influence of Pleistocene climatic changes on the phylogeography and demographic history of a cosmopolitan...
