Environmental Ecology Lab

I am a plant ecologist broadly interested in how organisms interact with their environment. Much of my research is in global change ecology, specifically on plant responses to climate-related disturbances. My research has focused on drought-induced tree mortality - including the physiological process of death from drought and its sensitivity to temperature, tree growth and phenological response to drought, and the ecosystem and earth system consequences of forest disturbance. My research approaches span subdisciplines, including plant physiological ecology, dendroecology, ecosystem ecology, and ecohydrology. I seek to increase understanding of the sensitivities and mechanisms of climate-related ecological responses with an application toward improved prediction of climate change and its effects on the biosphere and earth system.

An overview of the study of organisms interacting with each other and their environment at individual, population, community, and ecosystem levels of organization. Includes human interaction with ecological systems. Lecture and laboratory Component.
