Microbial community composition explains wintertime greenhouse gas fluxes in an oroarctic tundra ecosystem

Sirja Viitamäki, Eeva Eronen‐Rasimus, Anna‐Maria Virkkala…·Jenni Hultman

The paper examines microbial community composition and its impact on wintertime greenhouse gas fluxes in an oroarctic tundra ecosystem, showing that microbial activity explains GHG emissions beyond abiotic factors.
