Existing conservation efforts are insufficient to protect Antarctic ecosystems, and population declines are likely for 65% of the continent's plants and wildlife by the year 2100, according to a study by Jasmine Rachael Lee at the University of Queensland, Australia, and colleagues, published December 22 in the open access journal PLOS Biology. Implementing ten key threat management strategies—at an annual cost of 23 million U.S. dollars—would benefit up to 84% of terrestrial bird, mammal, and plant groups.
