A spreadsheet detailing the analysis of humpback whale biopsy samples including the field: Sample ID Duplicate (notes field) Location sample was taken Collection date (UTC) Collection latitude and longitude Sex Haplotype DLOOP sequence Microsatellite sequence Single nucleotide polymorphism (SNP) markersBy utilising both mitochondrial and nuclear genetic markers, the population structure and distribution of humpback whales that migrate to separate winter breeding grounds along the north-western and north-eastern coasts of Australia, and their interaction with the endangered populations of the South Pacific can be examined. Specifically, this dataset was used to look at population structure among putative breeding populations, the mixing of breeding populations on high latitude Antarctic feeding grounds and evidence for sex-specific migration along the eastern Australian migratory corridor.Australian Antarctic Data Centre Note, 2018-07-10: Original datasheet was reformatted to fit IPT Biodiversity.AQ standard. The new datasheet "humpbackWhales.csv" provides the dataset ID, decimal latitude and longitude, location, sex, occurrence, and date of event. The taxonomical organisation is provided to the lowest taxonomical rank that could be determined, after matched in WoRMS (World Register of Marine Species).
