Abstract The Weddell Gyre (WG) is one of the main oceanographic features of the Southern
Ocean south of the Antarctic Circumpolar Current which plays an influential role in global …

Human evolution has clearly been shaped by gene–culture interactions, and there is
growing evidence that similar processes also act on populations of non-human animals …

Killer whales (Orcinus orca) are currently recognized as a single ecologically and
morphologically diverse, globally distributed species. Multiple morphotypes or ecotypes …

The isolation of the Southern Ocean after the opening of Drake Passage some 23–25 million
years ago, the formation of the Antarctic Circumpolar Current, the subsequent cooling of the …

The availability of mitochondrial genome sequences is growing as a result of recent
technological advances in molecular biology. In phylogenetic analyses, the complete …

Killer whales, Orcinus orca, are top predators occupying key ecological roles in a variety of
ecosystems and are one of the most widely distributed mammals on the planet. In …

Long‐distance migration in whales has historically been described as an annual, round‐trip
movement between high‐latitude, summer feeding grounds, and low‐latitude, winter …

Reconstruction of the demographic and evolutionary history of populations assuming a
consensus tree‐like relationship can mask more complex scenarios, which are prevalent in …

Killer whales (Orcinus orca) have a global distribution, but many high‐latitude populations
are not well studied. We provide a comprehensive review of the history and ecology of killer …

Tunas are known for their extraordinary swimming performance, which is accomplished
through various specializations. The caudal keels, a pair of lateral keel-like structures along …
