How do introduced tree species interact with native mycorrhizal fungi?

Mycorrhizal symbioses are one of the most extensive and important biotic interactions in terrestrial ecosystems, typically providing plants with improved access to nutrients in exchange for carbohydrates produced via photosynthesis. This project will focus on the impact of introduced commercial tree species on native communities of symbiotic mycorrhizal fungi. By moving organisms into novel geographic areas, human activity has generated ‘no-analogue’ associations between plants and fungi (i.e. combinations of species that have not previously existed). Using a combination of lab, field, and statistical approaches, this project will examine the identity and function of symbiotic interactions between introduced North American tree species and native European fungi. Although this project will focus on Douglas-fir, other tree species may also be considered. The project will be based in the UK, but there may be opportunities for fieldwork in exotic plantations elsewhere in Europe, or in native forests in western Canada.

The supervisor is a Lecturer in Ecology in the School of Biological Sciences at the University of Reading. He has experience in applying experimental and modelling approaches in terrestrial ecology, and is particularly interested in both natural dispersal and assisted migration of tree species.
