Below-ground colors of Arctic greening: Explaining warming-induced changes in soil carbon stocks with shifts in soil microbial life strategies

Arctic greening

End day

31.08.2021

Goals

We will investigate how a shift towards increasingly shrub-dominated Arctic vegetation (greening) under a warming climate affects the soil microbial community composition and activity though litter and root exudate input, and how this impacts soil organic carbon decomposition and carbon dioxide emissions from Arctic ecosystems.

Outputs

The project will provide a fundamental contribution to our understanding of microbial C and N cycling mechanisms in the Arctic tundra and unravel how microorganisms inhabit and shape ecosystem functions in a changing climate.
