Tracking paper published in Nature

The Marine Biology Lab (Bruno Danis) was involved in a publication of in Nature in March 2020. Bruno Danis was a member of the data processing and analyzing team and participated in the drafting of the manuscript.

The paper is the result of a large data analysis which has direct implications for the conservation of large predators from the Southern Ocean. We assembled tracking data for 17 species to model Areas of Ecological Significance. Simultaneously, the data has been published in Open Access in the journal Scientific Data.

Abstract: Southern Ocean ecosystems are under pressure from resource exploitation and climate change. 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.
