Signals from the South; Humpback Whales Carry Messages of Antarctic Sea-ice Ecosystem Variability

Southern hemisphere humpback whales (Megaptera novaeangliae) rely on summer prey abundance of Antarctic krill (Euphausia superba) to fuel one of the longest-known mammalian migration on the planet. It is hypothesised that this species, already adapted to endure metabolic extremes, will be one of the first Antarctic consumers to show measurable physiological change in response to fluctuating prey availability in a changing climate...Click on the link below to preview the full article.
