Research Interests

From Plant to Ecosystem Ecology – Linking Levels and Crossing Scales

The research at the Sheffer lab aims at connecting plant strategies at the individual level to the organization of the ecological community and the functioning of the ecosystem. We study, for example, how plant strategies of nutrient acquisition are selected for by the conditions in the ecosystem and competition in the community; and conversely, how nutrient cycling is influenced by individual plant strategies. To answer such questions our research combines experiments, field observations and theoretical modeling, to evaluate links across spatial scales, from the local environment of the individual plant to landscape-scale processes (biotic and abiotic flows).

Currently looking for excellent MSc and PhD students!
