Richardson, John

We are interested in the ecological processes that limit populations and contribute to the assembly of communities, and how land use impacts those processes.  We use experimental manipulations of small streams and their riparian areas as our study system, and we have manipulated inputs, species composition, abiotic factors, physical structure, etc., to test hypotheses about these processes and how they contribute to biodiversity and ecosystem function.

Areas of research include:

• Stream ecology
• Riparian ecosystems
• Community and population ecology
• Benthic invertebrates, amphibians, fish
• Detrital-based food webs and donor-controlled systems
• Restoration ecology
