research overview

Dr. Lewis studies the water quality of streams, rivers, and wetlands in Colorado and the new world tropics. Both natural and disturbed conditions are of interest to him. He also analyzes aquatic food webs and aquatic communities and models aquatic ecosystem processes such as biomass production, responses to nutrients, and respiration.

keywords

Teaching

courses taught

EBIO 4030 - Limnology
Primary Instructor - Spring 2018 / Spring 2019 / Spring 2020
Examines the ecology of inland waters, including a detailed consideration of physical, chemical and biological properties of freshwater ecosystems: origins and major characteristics of lakes and streams, survey of chemical and nutrient cycles in freshwater habitats and survey of biotic composition of freshwater environments. Important themes in modern freshwater ecology are considered, including energy flow, trophic structure, eutrophication and management of freshwater ecosystems. Recommended prerequisites: EBIO 1210 and EBIO 1220 (minimum grade C-). Same as EBIO 5030.
