They may be small, but krill—tiny, shrimp-like creatures—play a big role in the Antarctic food chain. Climate change may cause the Antarctic krill growth season to end earlier and growth habitat to shift south. Recruitment, driven largely by the winter survival of larval krill, is probably the population parameter most susceptible to climate change. Antarctic krill – finger-sized, swarming crustaceans – might be small but they underpin … We provide a circumpolar assessment of the robustness of krill growth habitat to climate change by coupling an empirical krill growth model with projections from a … Ocean warming is likely to alter the distribution and lifecycle of ecologically and commercially important Antarctic krill over the rest of this century, according to new IMAS-led research. They may be small, but krill — tiny, shrimp-like creatures — play a big role in the Antarctic food chain. Krill, typically about the size of a pinkie and similar in appearance to shrimp, are one of the most abundant animal species on earth, and a cornerstone of the Antarctic ecosystem. But climate change is set to disrupt this delicate balance.
