The Soil Ecology and Global Change group focuses on the functional role of soil fauna in terrestrial ecosystems in the context of climate change. In particular, we have been trying to quantify soil biodiversity changes and their potential implications for ecosystem services that they govern (i.e. sustainable plant production, soil carbon sequestration, greenhouse gas mitigation, hydrological regulation). To achieve this we have developed a robust research profile on taxonomy and ecology of different soil organisms. We also combine the use of carbon and nitrogen stable isotopes as potential in situ tracers of the trophic structure of edaphic communities and radiocarbon techniques to investigate the interaction between soil fauna activities and the temperature sensitivity of soil organic matter decomposition. International involvement includes past and ongoing collaborations with UKCEH Lancaster, University of York, the NERC Radiocarbon Laboratory, University College of Dublin, University of Coimbra and JRC Ispra.
