Short summary
Carbon cycling in Himalayan mountain forest ecosystems is not well studied. We studied soil respiration and its autotrophic and heterotrophic components as well as the effects of environmental drivers in mixed and broadleaf forest ecosystems in the Bhutan Himalayas for the first time. Soil respiration rates were similar in the two forest ecosystems. A simple temperature-driven model was able to explain more than 90 % of the temporal variation in soil respiration.
