Research in my lab focuses on multiple areas of plant ecology, particularly on the interaction between plants and their resources, ranging from plant adaptations to low resource availability, to how plants influence soils and subsequently ecosystem function and biodiversity. Over the past two decades my work has concentrated on the interaction between alpine plants and nutrients, examining the response of plants to low nutrient supply, as well as the influence that plants have on their nutrient environment. Research projects have addressed specific resource limitations to primary production in alpine communities, the role of competition in community composition, the role of symbiotic N2-fixation in the alpine N cycle and its influence on species diversity, plant species influences on N cycling, and the influence of anthropogenic N deposition on ecosystems.

EBIO 2040 - Principles of Ecology
Lecture and laboratory. Introduces principles of ecology, emphasizing patterns and processes at various levels of biological organization. Scope global, but examples often from local environment. Laboratory emphasizes techniques of field biology. Uses animals and/or animal tissues. Recommended prerequisites: EBIO 1030 and EBIO 1040 and EBIO 1050 or EBIO 1210 and EBIO 1220 and EBIO 1230 and EBIO 1240 (minimum grade C-). Same as EBIO 2640 and ENVS 2000.
