Population genomics of shy and white-capped albatrosses using DArTseq
Published: 2026-05-18
This dataset includes population genomic data for shy albatross (Thalassarche cauta) and white-capped albatross (T. steadi). DNA samples from 6 breeding colonies (3 per species) were analysed using DArTseq (Diversity Arrays Technology reduced representation sequencing method: https://www.diversityarrays.com/) to generate single nucleotide polymorphism (SNP) genotypes for each sample. The dataset includes raw DNA sequence data, analysed data, and details of workflows used for analyses. Raw DNA sequence data are also available from NCBI SRA [accession numbers to be added once finalised]. This research was funded by Australia from its voluntary contribution to the Agreement on the Conservation of Albatrosses and Petrels. Data analyses were supported by Galaxy Australia, a service provided by Australian BioCommons and its partners (Galaxy Australia receives NCRIS funding through Bioplatforms Australia, as well as The University of Melbourne and Queensland Government RICF funding) and by use of the Nectar Research Cloud, a collaborative Australian research platform supported by the NCRIS-funded Australian Research Data Commons.
