英文摘要 | The impact of climate change on the circumpolar distribution of the key Antarctic food-web species, krill, is unknown. Combining a krill growth model with projected climate scenarios shows the growth habitat is likely to experience only moderate change, with the northern edges most at risk. Antarctic krill is a key species of important Southern Ocean food webs, yet how changes in ocean temperature and primary production may impact their habitat quality remains poorly understood. 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 weighted subset of IPCC Earth system models. We find that 85% of the study area experienced only a moderate change in relative gross growth potential (+/- 20%) by 2100. However, a temporal shift in seasonal timings of habitat quality may cause disjunctions between krill's biological timings and the future environment. Regions likely to experience habitat quality decline or retreat are concentrated near the northern limits of krill distribution and in the Amundsen-Bellingshausen seas region during autumn, meaning habitat will likely shift to higher latitudes in these areas. |
