Mitigation requires the identification and protection of Areas of Ecological Significance (AESs), which have so far not been determined at the ocean-basin scale. Here, using assemblage-level tracking of marine predators, we identify AESs for this globally important region and assess current threats and protection levels. Integration of more than 4,000 tracks from 17 bird and mammal species reveals AESs around sub-Antarctic islands in the Atlantic and Indian Oceans and over the Antarctic continental shelf. Fishing pressure is disproportionately concentrated inside AESs, and climate change over the next century is predicted to impose pressure on these areas, particularly around the Antarctic continent. At present, 7.1% of the ocean south of 40°S is under formal protection, including 29% of the total AESs. The establishment and regular revision of networks of protection that encompass AESs are needed to provide long-term mitigation of growing pressures on Southern Ocean ecosystems.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;font-family:"Times New Roman","serif";mso-fareast-language:ES'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;font-family:"Times New Roman","serif";mso-fareast-language:ES'>//////////////////////////////////////////////<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;font-family:"Times New Roman","serif";mso-fareast-language:ES'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;font-family:"Arial","sans-serif";mso-fareast-language:ES'>NATURE 18 March 2020 <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;font-family:"Arial","sans-serif";mso-fareast-language:ES'>doi: 10.1038/d41586-020-00640-1<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;font-family:"Times New Roman","serif";mso-fareast-language:ES'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:14.0pt;font-family:"Arial","sans-serif";mso-fareast-language:ES'>Satellite tracking of marine predators in the Southern Ocean has revealed key ecological areas under disproportionate pressure from human activities.

These tags provided location estimates (obtained using satellite information or other methods) as the animals migrated. The authors used some of these data (for 2,823 individuals) to develop predictive models to identify crucial habitats in the Antarctic region for all of the predator species combined.

Predators in the Southern Ocean include a large range of species from across different taxonomic groups. These include species living in the Antarctic region and species residing immediately north of it (in the sub-Antarctic), all with different diets and patterns of movement. The authors used a series of data-processing steps to generate a value they termed ‘habitat importance’, which they predicted using data across all of these species together (assemblage-level maps). To do this, Hindell and colleagues first mapped habitat importance for the species living in the Antarctic separately from those living in the sub-Antarctic, and then selected the maximum habitat-suitability values in those two maps to generate an overall assemblage-level map for all of the predator species combined.<o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=EN-US style='font-size:12.0pt;font-family:"Arial","sans-serif";mso-fareast-language:ES'>Finally, the authors defined the regions in the top 10% of their calculated habitat importance value as the areas of the most ecological significance in the Southern Ocean.
