Shifts in Microbial Thermal Traits Mitigate Heat-Induced Carbon Losses in Soils.

ABSTRACT: Global warming is expected to transfer carbon from soil organic matter to atmospheric CO₂, with microbial communities playing a crucial role in regulating this exchange. While the immediate impact of temperature on microbial functions is well understood and causes soil carbon losses, the long-term response remains unclear, with losses stabilising over time, reducing the overall effect of chronic warming on soil organic carbon (SOC) stocks. Here, we examined the temperature dependence of microbial respiration and growth after 9 years of +5°C warming in a temperate forest. Using these temperature dependences and field temperature data, we modelled in situ carbon fluxes and changes in SOC stocks. Results showed that the direct effect of temperature initially increased respiration a
