Soil models include a key parameter known as carbon use efficiency, which impacts estimates of global carbon storage by determining the flow of carbon into soil pools versus the atmosphere. Microbial-explicit versions of these models are due for an update that recasts carbon use efficiency as an output variable emerging from microbial metabolism.

AbstractMicrobial carbon use efficiency (CUE) affects the fate and storage of carbon in terrestrial ecosystems, but its global importance remains uncertain. Accurately modeling and predicting CUE on a global scale is challenging due to inconsistencies in measurement techniques and the complex interactions of climatic, edaphic, and biological factors across scales.

replying to E. D. Osburn et al. Nature Microbiology https://doi.org/10.1038/s41564-024-01687-w (2024)In a recent paper, we used soil metagenomes from global biomes to assess life history strategies across soil bacterial communities1. We compiled 102 traits in a multi-table coinertia analysis to characterize the life history strategies of soil bacteria.

HighlightsDrought frequency and intensity are increasing with climate change. Soil microbes cope with drought through physiological acclimation, dispersal, shifts in community composition, and evolutionary adaptation. By acting as decomposers, microbes control the loss of carbon from soil. Physiological, ecological, and evolutionary responses allow microbes to sustain losses of carbon from soils experiencing drought. AbstractDroughts are becoming more frequent and intense with climate change.
