Low levels of genetic differentiation characterize Australian humpback whale ( Megaptera novaeangliae) populations
Abstract Humpback whales undertake long‐distance seasonal migrations between low latitude winter breeding grounds and high latitude summer feeding grounds. We report the first in‐depth population genetic study of the humpback whales that migrate to separate winter breeding grounds along the northwes...

Abstract Humpback whales undertake long‐distance seasonal migrations between low latitude winter breeding grounds and high latitude summer feeding grounds. We report the first in‐depth population genetic study of the humpback whales that migrate to separate winter breeding grounds along the northwestern and northeastern coasts of Australia, but overlap on summer feeding grounds around Antarctica. Weak but significant differentiation between eastern and western Australia was detected across ten microsatellite loci ( F ST = 0.005, P = 0.001; D EST = 0.031, P = 0.001, n = 364) and mitochondrial control region sequences ( F ST = 0.017 and Φ ST = 0.069, P = 0.001, n = 364).
