Soil and climate feedbacks in mycorrhizal biogeography and ecology
Mycorrhizal fungi (MF) are ubiquitous soil fungi that can form symbiotic associations with the majority of terrestrial plants. MF can facilitate plant uptake of mineral nutrients and water, organic matter mineralization and stabilization, buildup and stabilization of soil aggregates, and improve plant resistance to various environmental stresses such as drought, pathogens and soil contamination. As the physiological and ecological functions of MF could be predetermined by their ecological adaptability, it is important to reveal the MF biodiversity and their response to environmental changes and anthropogenic pressures. With the development and application of molecular-based methodologies, remarkable progress has been achieved in the fields of mycorrhizal ecology and biogeography in recent years. This session will thus focus on:
- mycorrhizal biogeography at different spatial scales, and influences of biotic and abiotic factors on the distribution of MF
- responses of MF community structure and function to climate change and anthropogenic activities
- interplay between plant and fungal communities along environmental gradients (e.g., soil and climate)
- ecological significance of MF in mineral weathering, soil aggregation, biogeochemistry of carbon, nitrogen and phosphorus, and water conservation and utilization, in different environmental settings.
