BVOC emissions from northern mires and heaths

Riikka Rinnan, associate Professor, CENPERM/Department of Biology

Biogenic volatile organic compounds (BVOCs) play an important role in many atmospheric processes and have indirect feedback effects on global warming. Our recent in situ measurements in the Subarctic suggests that BVOC emissions from high latitude ecosystems are more temperature sensitive than the emissions from temperate ecosystems, as warming by only two degrees doubled the emissions. In growth chamber studies with peatland mesocosms we have assessed how temperature, water table depth and vegetation composition affect the BVOC emissions from boreal mires. It appears that a significant part of the emissions originates from anaerobic processes in the peat.
