Moss species on the move in East Antarctic terrestrial communities
Antarctica has experienced major changes in temperature, wind speed and stratospheric ozone levels over the last 50 years. Whilst West Antarctica and the peninsula showed rapid warming and associated ecosystem change, East Antarctica appeared to be little impacted by climate warming, thus biological...

Antarctica has experienced major changes in temperature, wind speed and stratospheric ozone levels over the last 50 years.
