Research Theme within School of Biosciences: Organisms and Environment
Short research description: Physiological plant ecology
Key Research Interests:
I am an ecologist with interests in the interactions between plants and their environment (physical and biological). For my three areas of research, specific examples are listed below.
Global environmental change
Impacts of atmospheric nitrogen deposition on upland vegetation: first demonstration of the impact of pollutant N on a British natural ecosystem (blanket bog) and the mechanism of action.
Impacts of climate change on arctic ecosystems: community changes to temperature and nutrients are mediated through the response of a small number of key species already present in the community with no invasion of new species.
Parasitic plant-host interactions
Interactions between parasitic witchweeds (Striga species) and their hosts: quantification of host-parasite carbon budget and identification of host resistance mechanisms.
Impacts of parasitic plants on ecosystem structure and function: hemiparasites shape community structure through acceleration of decomposition and nutrient (nitrogen) cycling.
Regeneration of rain forest tree seedlings (dipterocarps): growth enhancement under elevated CO2 is greater under sunflecks and thus may alter the trade off between growth in the sun and survival in the shade for dipterocarp seedlings.
