• Changes in soil oxidase activity induced by microbial life history strategies mediate the soil heterotrophic respiration response to drought and nitrogen enrichment (2024) · Frontiers in Microbiology · cited 22× · doi

  The complexity of soil microbial communities and the difficulty of measuring their activities and interactions. The challenge of disentangling the effects of extrinsic factors and microbial mechanisms on soil heterotrophic respiration. The need for a better understanding of the relationships between microbial life strategies, extracellular enzyme activities, and soil heterotrophic respiration.

  the Biolog EcoPlate assay only includes relatively simple, water-soluble, low-molecular-weight compounds, and none represent truly recalcitrant soil organic matter components, - the observed increase in the relative utilization of polymers and phenolic compounds in forest soils should be interpreted strictly as a community-level functional shift within the constraints of the EcoPlate assay, - interpretations remain appropriately bounded by the methodological scope of the technique

  To address this gap in knowledge, we investigated the direct effect of microbial community composition, activity, and diversity, as well as their associated metabolites on the development and persistence of SWR by inoculating microcosms containing model soils with 15 different microbial communities and quantified respiration and SWR over time.
