Biodiversity of a Unique Environment: The Southern Ocean Benthos Shaped and Threatened by Climate Change.
Over millions of years, plate tectonics, palaeoceanography and the resulting changes in the global climate (greenhouse to icehouse) have impacted the Southern Ocean marine fauna and flora, caused evolutionary extinctions and radiation of benthic marine invertebrates, and led to the present biodivers...
