SES is a global priority for terrestrial biodiversity conservation and is home to two important biodiversity hotspots-the Atlantic Forest and Cerrado-which are among the world's most studied biodiversity hotspots in connection with climate-change impact on biodiversity, especially for terrestrial vertebrates . An increasing number of studies show that the Atlantic Forest and Cerrado are at risk of biodiversity loss, largely due to projected reductions of species' geographic distributions in many different taxa . Cerrado savannahs are projected to be the hotspot most negatively impacted by climate change within SA, mostly though range contraction of plant species , while the Atlantic Forest is projected to be highly impacted especially though the contraction of the distribution of endemic species   . Reductions in species' distribution are also projected in the River Plate basin for sub-tropical amphibians  and the river tiger , a keystone fish of economic value . Farming of mussels and oysters in the region is predicted to be negatively impacted by climate change, particularly SLR, and ocean warming and acidification . Some more localised habitats are also at risk of losing area due to climate
