Plant ecophysiology and ecosystem processes

Researching plants and their environment, and ecosystem processes
Our research looks at ecosystem processes, and how plants are affected by and cope with their environment. This research includes the internal activities of plants.

Our research

Our research is organised into two basic themes. The first theme is how plants are affected by and cope with their environment. The scope of this research includes the internal activities of plants. That is those chemical and physical processes associated with life (e.g. photosynthesis, respiration, gas exchange, nutrient uptake). Some of the research projects within this theme are:

  • Metabolomics as a tool to investigate stress tolerance mechanisms
  • Photosynthesis and diffusion of CO2 within leaves
  • How plants cope with constant versus “pulsed” supplies of nutrients and water

The second major theme encompasses ecosystem processes, in particular cycles of C, N, P. Some of the research projects within this theme are:

  • The cycling of organic N in soils
  • Uncovering how water availability affects soil respiration
  • Adaptation and acclimation of soil microbes to N and P
  • Interaction between plants and soil
  • Soil processes at cold temperatures (e.g. under snow)
