Scientists have published one of the largest genetic studies ever conducted on the humpback whale (Megaptera novaeangliae) for the purpose of clarifying management decisions in the Southern Hemisphere and supporting calls to protect unique and threatened populations, according to WCS (Wildlife Conservation Society), the American Museum of Natural History, Columbia University, and other organizations.

Using data generated from more than 3,000 skin samples from individual whales ranging from the South Atlantic to the Indian Oceans, the research team has uncovered previously unknown degrees of relatedness between different whale populations. The study will also help inform ongoing conservation reassessments of humpback whale populations, and reaffirms the highly distinct nature of a small, non-migratory population of humpback whales living in the Arabian Sea in need on continued protection.

The study titled "Multiple processes drive genetic structure of humpback whale (Megaptera novaeangliae) populations across spatial scales" appears in the the journal Molecular Ecology.
