Decomposers in Transition
EMSL Project ID
49699
Abstract
The overarching objective of the research is to develop a scalable approach for understanding how soil decomposer community dynamics are affected by spatial heterogeneity and climate change (drought). Successful completion of this project will address a critical gap in our understanding of soil biogeochemistry, which is the role of connectivity and niche differentiation in regulating the availability of substrates, the distribution of taxa, and the hydraulic connectivity of soil micro-habitats, all of which have implications for threshold and regime shifts in C cycling dynamics. This work applies state of the art PNNL capabilities including activity-based protein profiling, microscopy, and microbially explicit models to identify key organisms and enzymes involved in cellulose degradation over a range of complexities in spatial structure and hydrology.
