The Arctic is warming more rapidly than any other region in the world. There, permafrost soils cover ~25% of terrestrial surface and hold the world's...

Nutrient cycling
 

Nitrogen (N) is essential for all life on Earth and the most abundant element in the atmosphere, where it mainly occurs as dinitrogen gas (N2)....

Nutrient cycling
 

The Amazon rainforest stores large amounts of carbon in plant biomass and in soils, and is an important sink for atmospheric CO2 setting off increased...

Nutrient cycling
 

Effects of bryophytes on soil microbial processes and nitrogen cycling.

In high latitude ecosystems bryophytes (mainly mosses) are important drivers...
