英文摘要
This project aims to determine the role of soil-inhabiting pathogens and symbiotic fungi in the maintenance of plant diversity in Australia’s hyperdiverse shrublands. These are among the world’s most species-rich systems, yet occur on extremely poor soils. This project tests the hypothesis that plants that are best adapted to acquire phosphorus in these extremely infertile soils are most susceptible to soil pathogens. This trade-off would equalise differences in competitive abilities among plant species and promote high plant diversity. The project will help elucidate how pathogens and symbiotic fungi together drive plant diversity in a globally significant biodiversity hotspot in Australia, with relevance to other biodiverse regions.
