- Abstract:
- Process-based 'Earth system' model simulations indicate that reduced emissions of volatile organic compounds (VOCs) from terrestrial vegetation played a major role in determining glacial atmospheric CH4 levels. They identify CO2 and climate as important regulators of plant VOC emissions via through their influence on canopy biomass and leaf-scale emission rates. Our proposal will experimentally test this hypothesis by growing isoprene emitting herbaceous taxa at glacial (180ppm), Holocene (280ppm) and modern-day 'control' (350 ppm) CO2 concentrations in whole-plant controlled environment chambers under warm and cool climates. We will use proton transfer mass spectrometry to measure the impact of each growth CO2 concentrations on leaf and canopy scale VOC emissions, and characterize their responses to irradiance and temperature gradients.
