Return of the right whale: assessment of abundance, population structure and geneflow in the New Zealand southern right whale
Southern right whales were hunted to near extinction, with an estimated 150,000 killed by intensive 19th century and illegal 20th century whaling. This thesis focuses on the coastal calving grounds of New Zealand (NZ) and Australia, where previous genetic work and survey work suggests 2 genetically...
