Soil warming decreases microbial functional diversity in the Arctic Tundra
Soil warming decreases microbial functional diversity in the Arctic Tundra

Figure below shows microbial functional diversity decrease during incubation with the organic layer soil at 8 °C. Microbes also express higher levels of glycosidase genes in organic than mineral soils during incubations, producing more reducing sugars and initially higher levels of CH4 and CO2.
