Howard E. Epstein
Sidman P. Poole Professor
My current research efforts are in the arctic tundra of North America and Russia, and the temperate forests of the U.S. Mid-Atlantic. In the Arctic, we are examining the recent dynamics of arctic tundra vegetation in response to changing climate and disturbances, and the effects that these vegetation changes have on other arctic ecosystem properties. In the U.S. Mid-Atlantic we are examining carbon cycling along successional gradients from old-field to old-growth, as well as carbon-water interactions in topographically complex watersheds.

Teaching
Terrestrial Ecology (EVSC 5220)
Analyzes the patterns and processes in terrestrial ecosystems. Topic include macro- and micro-meteorological factors such as producer, consumer, and decomposer processes; hydrologic and biogeochemical pathways; and changes through space and time.
Fundamentals of Ecology (EVSC 3200)
Studies energy flow, nutrient cycling and allocation in natural ecosystems, organization of species at the population and community levels, and interaction between people and the biosphere.
