Steven S Perakis
I am a Supervisory Research Ecologist at the Forest and Rangeland Ecosystem Science Center in Corvallis, OR
I am interested in forest biogeochemistry and ecosystem studies, watershed science, riparian forests, global change, nutrient cycling, forest soil fertility and stable isotopes.
