The Southern Ocean represents a continuous stretch of circumpolar marine habitat, but the potential physical and ecological drivers of evolutionary genetic differentiation across this vast ecosystem remain unclear. We tested for genetic structure across the full circumpolar range of the white-chinned petrel (Procellaria aequinoctialis) to unravel the potential drivers of population differentiation and test alternative population differentiation hypotheses. Following range-wide comprehensive sampling, we applied genomic (genotyping-by-sequencing or GBS; 60,709 loci) and standard mitochondrial-marker approaches (cytochrome b and 1st domain of control region) to quantify genetic diversity within and among island populations, test for isolation by distance, and quantify the number of genetic clusters using neutral and outlier (non-neutral) loci. Our results supported the multi-region hypothesis, with a range of analyses showing clear three-region genetic population structure, split by ocean basin, within two ... : Rexer-Huber_WCP_cytb.fasta is haplotypes of the mitochondrial cytochrome b haplotypes (~1200 bp) for white-chinned petrels, produced via Sanger sequencing on an ABI 3730xl DNA analyser. Rexer-Huber_cytb_haplotype-sample_table.xlsx links haplotype names to the original petrel samples. Rexer-Huber_WCP_CR1D.fasta is haplotypes of the first domain of the mitochondrial control region (~559 bp) for white-chinned petrels, produced by Sanger sequencing on an ABI 3730xl DNA analyser. Haplotypes are named according to sample and location of origin. File Rexer-Huber_GBS_s_4_fastq.txt.gz is the raw reads produced by genotyping-by-sequencing. Genomic DNA was digested with PstI and MspI. Size selection to 193-500 bp. Library sequenced on Illumina HiSeq2500 using single-end reads, with 101 cycles in high-output mode (v4 chemistry). Rexer-Huber_GBS_barcodes.txt is the barcodes. Further datasets are stored on the Molecular Ecology website as Supporting Data files with the publication. These are: Supp Data A WCP outliers.xlsx ...
