William  Lewis
Research Interests Freshwater ecology and limnology. Topics of special recent interest include (1) the systems ecology of tropical lakes and rivers; (2) adaptation and ecology of plankton, especially phytoplankton; (3) chemistry of atmospheric deposition, especially as it relates to nutrient mass balance in ecosystems; (4) the trophic ecology of lakes; and (5) water quality and limnology of lakes and streams in Colorado.
