Forests

Ecosystems are threatened by a multitude of environmental stresses ranging from disturbance at local scales to global climate change. I am interested in how ecosystems respond to environmental stress, which also requires a greater understanding of how stresses impact on ecosystems. My research focuses on the impacts of acid rain, climate change, nutrient depletion, forestry and metals on forest and lake ecosystems. The research studies range from long-term catchment scale programs to short term laboratory isotope tracer experiments.
