Seasonal and Elevational Variability in Dwarf Birch VOC Emissions in Greenlandic Tundra
Rising temperatures amplify biogenic volatile organic compound (VOC) emissions from Arctic vegetation, causing feedbacks to the climate system. Changes in climate also alter plant physiology and vegetation composition, all of which can influence VOC emissions. Moreover, leaf development and biotic s...
