Abstract
Lecture given by Dr T. Matthew Robson, Associate Professor in Forestry, University of Cumbria. Ecosystem primary productivity is underpinned by light capture through photosynthesis by leaves. Leaves adjust their capacity for photosynthesis according to the light conditions through structural and physiological acclimation. These adjustments occur in response to diurnal and seasonal changes in the light environment according to cloudiness, atmospheric chemistry, sun angle and a leaf’s positions within a plant canopy. Focussing on the key differences between the photosynthetic assimilation by plant canopies under diffuse and direct radiation, I will consider our capacity to upscale carbon budgets from leaves to canopies and further to the ecosystem level. Existing models draw on knowledge of immediate responses to diffuse radiation but neglect longer-term acclimation of canopy structure and changes in allocation patterns. This knowledge is needed to forecast how on-going changes in our environment are likely to affect primary productivity and feedback to ecosystem carbon sinks and food production.
