The long-term goal of my research program is to unravel the functional link between soil fungal communities and nutrient and carbon cycling in terrestrial ecosystems. This is achieved by first establishing ecological principles that describe fungal communities in soil. The proposed research program analyses carbon utilization and phosphorus acquisition to identify adaptive traits and explore general principles that govern the structure of highly diverse communities of root associates soil fungi. Firstly, comparative genomics will be used to analyze evolutionary diversification and phylogenetic specificity along the trophic continuum from root symbiosis to decomposition for the ubiquitous soil fungal class Archaeorhizomycetes. Secondly a ?Reverse ecology? approach is adopted to identify traits, i.e. genes and metabolic pathways, which adapt communities to specific forms of phosphorus in soil. Phosphorus speciation in soil is proposed as a natural environmental constraint that shape below ground fungal communities under the hypothesis that root associated fungi exhibit different adaptive strategies to acquire this essential and highly immobile nutrient from soil. These studies are important because they will provide the first trait-based analysis of soil fungal biodiversity. Functional traits form a functional link between diversity and ecosystem processes and have the potential to be used as biomarkers and as input parameters for future modeling of soil processes.
