Scaling the Microbial Ecology of Soil Carbon
EMSL Project ID
50122
Abstract
We propose to determine the ecology of soil microbial responses to experimental warming, by utilizing EMSL capabilities to quantifying growth, mortality, and C use and growth efficiency, as modulated by ecological stress, and on a taxon-specific basis. Our work combines sequencing the 16S rRNA genes, metatranscriptomes, metaproteomics, metabolomics, stable isotope probing, matrix modeling of soil biochemistry, and population ecological modeling. Our work spans arctic, boreal, temperate, and tropical ecosystems, and will investigate the microbial ecology of soil C in four DOE- or NSF-supported long-term climate-warming experiments, one in each of these major climatic zones. The cross-system comparison supports our interests in testing general hypotheses about microbial responses to temperature, and in the process, addresses fundamental ecological questions about these organisms.
