Summary
This global meta-analysis examines the mechanisms underlying variation in soil microbial respiration responses to warming. The authors report that microbial biomass carbon and nitrogen contents explain patterns in warming-induced changes to microbial respiration across diverse soils and climate zones, suggesting these are key mediating factors rather than soil properties alone.
UK applicability
Findings are relevant to UK soil management and carbon cycling predictions under projected warming scenarios, particularly for temperate agricultural and grassland soils where microbial respiration significantly affects soil carbon stocks and greenhouse gas emissions.
Key measures
Soil microbial respiration rates (likely CO₂ evolution), microbial biomass carbon, microbial biomass nitrogen, temperature effects
Outcomes reported
The study identified global patterns in how soil microbial respiration responds to warming and investigated the role of microbial biomass carbon and nitrogen as explanatory variables across diverse soil types and climates.
