Physiological plant ecology, stable isotope biogeochemistry
Research Description:
Research in my laboratory focuses on the interface between plants and their environment. The tools of physiological and evolutionary plant ecology and stable isotope biogeochemistry are currently being applied towards the study and interpretation of this interface. Investigations draw upon a variety of physiological methods, modeling and the use of stable isotopes as avenues for improving our understanding of how the ecophysiological characteristics of plants are shaped by and respond to the environments they inhabit. Projects pay special attention to how aspects of plant form and function combine to permit adaptation to environmental variation, whether naturally or anthropogenically imposed, and how plants and their unique traits influence the structure and function of the communities and ecosystems they compose.
Current research themes include:
exploring how the ecological and physiological characteristics of plants influence community and ecosystem processes (e.g. how the water, carbon and nutrient relations of plants may influence ecosystem hydrology and biogeochemistry);
elucidating the functional evolution and origin of adaptations in plants particularly with regards to how tolerance to low soil nutrient status, periodic drought, or low light and disturbance arises and the importance of evolutionary history in the origins of these adaptations; and
examining at the fluxes and exchanges of materials such as carbon, water and nitrogen between organisms and their biotic and abiotic environments using novel stable isotope techniques. Such an approach is proving to be especially powerful in looking at the origin of CO2 from different ecosystems and the exchange of water and nitrogen between plants and their fungal symbionts (mycorrhiza & endophytes) or their neighbors.
