Parched: quantifying microbial ecophysiology and the fate of plant carbon during soil dry down

Lead Institution

Lawrence Livermore National Laboratory

Principal Investigator

Project type

FICUS Research

In seasonally dry grasslands, soil microbes bloom during the plant growing season, survive extreme desiccation (water potential < -35 MPa) during long dry periods, and then rapidly mineralize soil…

Investigating the carbon cycling implications of changing microbial leaf litter decomposition across a permafrost thaw gradient.

Lead Institution

University of Arizona

Principal Investigator

Scott Saleska

Project type

FICUS Research

Thawing arctic permafrost (which contains 30-50% of global soil carbon) is expected to drive substantial alterations to carbon (C) cycling that will accelerate climate change. As permafrost thaws,…

Understanding Carbon Use Efficiency in Soil Ecosystems Using Metabolomics, Lipidomics, Protein Digests and Metabolic Modeling

Lead Institution

Northern Arizona University

Principal Investigator

Paul Dijkstra

Project type

Exploratory Research

The efficiency with which organic compounds are used to produce microbial biomass is an important variable in modeling soil C cycling. This efficiency, called C use efficiency or CUE, is often…

Microbes persist: Systems biology of the soil microbiome
