Global fire regimes are changing, becoming more frequent and more severe. These changes irrevocably alter plant and soil communities, potentially affecting important interactions between plants and symbiotic soil mutualists. Changing plant-soil mutualisms influence crucial ecosystem functions such as nutrient cycling, soil carbon storage and plant growth, as well as above- and below-ground biodiversity. However, the effects of changing fire regimes on plant-soil interactions remains a significant research gap.
The project will undertake a comparative study of fire-plant-soil interactions in heathlands globally. In these systems, several major shrub taxa form specialised symbioses with mycorrhizal fungi in the soil, but the effects of fire on these interactions are poorly understood. This project will seek to identify:
1) how fire affects plant-mycorrhizal symbioses; 2) the ecological and/or functional consequences of these effects; and 3) whether and how effects vary with local context.
Possible approaches include field and glasshouse experiments, laboratory techniques and statistical modelling, depending on student interests. There is scope for the student to develop the project in line with their own research interests, and it would suit those with an interest in plant community ecology, microbial ecology, or nutrient cycling. There will be opportunities to collaborate with research groups in Europe and/or Australia.
Novelty & Timeliness
The increasing frequency of fires globally suggests an urgent need to understand the impacts of fires on ecosystems. However, it is only relatively recently that the crucial role of plant-soil interactions for ecosystem processes and biodiversity has been recognised and we know very little about the effects of fires on plant-soil interactions. Increased understanding of the soil ecosystem sets the stage for addressing this important research gap.
