Marine species on the move

A new study by UC Santa Barbara researchers predicts that climate change will cause significant reshuffling of marine biodiversity, with warming oceans leading to the relocation of nearly 13,000 species. This redistribution is expected to increase biodiversity in many areas but also lead to extinctions and homogenization of communities.
