Climate change leads to higher NPP at the end of the century in the Antarctic Tundra: Response patterns through the lens of lichens
Poikilohydric autotrophs are the main colonizers of the permanent ice-free areas in the Antarctic tundra biome. Global climate warming and the small human footprint in this ecosystem make it especially vulnerable to abrupt changes. Elucidating the effects of climate change on the Antarctic ecosystem...
