Lost Millennium of Galápagos Deep-Sea Corals Linked to Major Pacific Climate Shift
The research, led by the University of Bristol in collaboration with international scientists and published in PNAS today [insert date], analysed more than 900 fossil deep-sea stony corals collected from depths of up to 1,000 metres.
Fires, Droughts, and Windstorms Reduce the Diversity of Amazonian Vegetation
