The objective of the project is briefly to test the hypothesis that understory shifts towards increased C3 dominance under eCO\u2082 are driving corresponding changes in AM fungal communities and their traits in a manner that decreases C storage in the system. <\/i><\/p>

We have sampled soil, roots, and leaves from C3 and C4 herbaceous plants in the EucFACE rings, as well as roots of Eucalyptus, and plan to have data on biogeochemistry (nutrient pools & mineralization rates, OM fractions, etc.) and microbial communities (ITS sequencing) from all those samples, meta-transcriptomics from a subset of samples, and possibly meta-genomics from a subset of samples. <\/i><\/p>

A greenhouse experiment (factorial C3\/C4 plants x eCO\u2082\/aCO\u2082 soils x\u00a0 eCO\u2082\/aCO\u2082 environment) will measure similar things, plus additional AM fungal traits. We also have several modeling projects planned that will utilize all these data to better understand the importance of C3 & C4 vegetation and microbial traits in C\/N\/P cycling. <\/i><\/p>

We are also collaborating with EucFACE scientists to analyze community, proteins, lipids, and metabolites in the time-series samples from EucFACE.<\/i><\/p>
