The investigates how plants and communities respond to various environmental perturbations including UV-B radiation, elevated concentrations of CO2, N deposition and elevated air temperature. Field experiments and glasshouse studies (in the UK and abroad) are used to study the simulated effects of climate change factors on semi-natural and agricultural systems. Plant physiological responses and interactions with other trophic processes (including herbivores, soil and decomposition, herbivores) are also investigated.
