研究领域

Plant-to-soil carbon fluxes. Quantitative analysis of carbon fluxes from plants to soil in grasslands and forests, and the storage of carbon in soils and vegetation. Development of methods for carbon budgeting in urban greenspace and its potential contribution to sustainable urban environments. Mycorrhizal fungi- their networks of power and influence - from nano-to-global scales. Use carbon isotope tracers to quantify energy passing from plants to their symbiotic root-infecting mycorrhizal fungi and how it is used by these fungi: (i) To drive mineral weathering, (ii) in nutrient and carbon cycling and (iii) to empower interactions with other soil organisms (fungi, plants, and fungal-feeding collembolans). Myco-heterotrophy: plants parasitic on fungi. About 10% of all plant species are myco-heterotrophic for part of their life, including most orchids. Over 400 species are fully myco-heterotrophic. My interests are in understanding their evolution, adaptive features, life-cycles, ecology, physiology, functioning and their critical fungal partners. Specialised root functioning. Root adaptations as an alternative strategy to mycorrhiza- spatial and temporal foraging precision and uptake of phosphorus by dauciform roots in sedges. Pollution impacts on plants, soil biology and chemistry, and health. Impacts of long-term nitrogen pollution on grassland soil and plant ecology, and recovery following reduced pollution inputs. Health risks and benefits associated with urban food production. Effects of urban greenspace and soils in trapping and sequestering black carbon.
