I combine theoretical and experimental approaches to investigate how interactions among species allow for or prevent their coexistence, and how the number and identity of coexisting species (i.e., diversity) influences the collective performance or functioning of ecosystems.
Current investigations center on two main questions:
- Does the size distribution of organisms determine the temporal stability of a food web?
- Currently, we are incorporating metabolic demands and size based consumption into models of food webs to investigate how consumers influence the stability of lower trophic levels and entire ecosystems, and how generalist versus specialist consumers influence plant production and stability.
- How does species diversity influence functioning?
- We are testing whether some of the insights from previous biodiversity – ecosystem functioning research will allow us to more effectively restore coastal dune plant communities.
