Summary: Microbes play a crucial role in cycling carbon through soils, and understanding their physiological response to warming is important for predicting soil carbon stocks under climate change. This study investigated the long-term impacts of warming on microbial physiology and found that microbial thermal acclimation and changes in substrate availability both contribute to these impacts. Additionally, seasonal inputs of fresh litter counteract the apparent thermal acclimation of carbon-cycling processes in response to warming. These findings highlight the indirect effects of long-term warming on microbial physiology and suggest the need for earth system models to incorporate these feedbacks.

Summary: A study conducted on agroecosystems explored the effects of long-term warming on microbial functions in the soil. It found that higher temperatures led to increased microbial growth but decreased the proportion of growing microbial biomass. The study also showed that increased availability of labile organic matter weakened the thermal acclimation of soil microbial functions. These findings suggest that the predicted impact of climate warming on soil microbe-driven CO2 emissions may be underestimated.

Summary: This study explored the dynamics of soil organic carbon (SOC) stock in response to experimental phosphorus (P) additions. The results showed that P additions significantly increased SOC stock globally, with the effect depending on soil nitrogen (N) availability. Under high N availability, P additions mainly increased plant biomass and litterfall, while under low N availability, P additions not only increased plant biomass and litterfall, but also soil microbial biomass and oxidase activity. However, the increases in aboveground biomass and litterfall did not lead to corresponding carbon accumulation in the soil, possibly due to microbial CO2 release. Reactive N input reduced P-addition-induced carbon loss and enhanced the effect of P additions on SOC.

Summary: Soil microbial carbon use efficiency (CUE) is an important parameter for evaluating soil carbon partitioning between microbial growth and respiration. However, there is controversy regarding general patterns of microbial CUE among different terrestrial ecosystems. This study collected and analyzed data from 41 study sites, including farmland, grassland, and forest ecosystems, to estimate microbial CUEs. The results showed significant differences in CUE among these ecosystems, with grassland soils exhibiting higher microbial C sequestration potentials. The study also identified metabolic limitations and environmental factors that influence microbial CUE. These findings provide insights into soil microbial C sequestration capacity and its response to global change.

Summary: The paucity of investigations on carbon dynamics in soils with warming makes it difficult to evaluate the feedback of terrestrial carbon to climate change. In this study, the researchers examined microbial carbon use efficiency (CUE) in an alpine grassland on the Qinghai-Tibetan Plateau and found that CUE decreased with soil depth, primarily controlled by soil carbon availability. However, experimental warming had limited effects on microbial CUE and soil carbon availability.

Summary: This study conducted an integrated assessment of the interactions between different organic amendments and soil microbial response variables, focusing on the priming effect and soil organic carbon sequestration. The findings suggest that the hot water extractable to total carbon ratio is the best predictor of the priming effect, the dissolvable to hot water extractable carbon ratio is closely related to variation in microbial response variables, and the priming effect is significantly correlated with changes in several microbial response variables. These findings advocate for the adoption of energetic principles in modeling and predicting microbially-mediated soil carbon dynamics, and highlight the importance of using organic amendments with high hot water to total carbon concentrations for more efficient soil organic carbon sequestration.

Summary: Efforts to manage soil carbon sequestration in bioenergy agriculture are limited by our understanding of how plant and microbial traits influence the formation of soil organic carbon (SOC). This study compared the litter of corn and miscanthus and found that the easy decomposability of corn litter promoted greater microbial carbon use efficiency and the formation of more mineral-associated SOC compared to the more complex miscanthus litter. The study also showed that modeling microbial trait differences improved the prediction of litter carbon fate in SOC. This research provides insights into the importance of litter quality and microbial efficiency in SOC formation and offers a basis for modeling SOC transformations.

Summary: Soil microorganisms play a crucial role in biogeochemical cycles, but their response to fires is not well understood. A global meta-analysis of 371 cases from 81 published studies was conducted to explore the comprehensive effects of fires on soil microbial properties. The results show that fires increase microbial metabolic quotient and decrease soil microbial biomass carbon and fungal biomass. The intensity of the fire and ecosystem types and climate zones also impact these responses.

Summary: In this study, the changes in soil organic carbon (SOC) relative stability following afforestation were explored, and the underlying mechanisms were investigated. The results showed that afforestation significantly increased the concentration of all carbon fractions but decreased SOC relative stability. Microbial carbon use efficiency (CUE) was found to have a significant and positive relationship with the proportions of stabilized C in total SOC. Overall, this study revealed the decline in SOC relative stability following afforestation, and provided new insights into the assessment of carbon neutrality under global afforestation.

Summary: This study demonstrates that climate warming reduces the resistance and resilience of wetland ecosystems to severe flooding. The warming experiment showed that plant community structure changed rapidly under warming, leading to a reduction in vegetation productivity's resistance to flooding. Additionally, slower post-flooding carbon processes were observed under warming. These findings suggest an increased impact of extreme hydrological events on wetland ecosystems in a warmer climate.

Summary: This study explores the relationship between hydraulic traits and the mortality and recovery of subtropical evergreen broadleaf forests (SEBF) trees. The results show that species with greater embolism resistance have longer survival time and exhibit higher resistance and faster recovery of photosynthesis and transpiration under drought conditions. Other plant traits cannot explain the interspecific variation in drought resistance and recovery. This highlights the unique importance of embolism resistance in driving carbon and water processes in SEBFs.

Summary: Nitrogen agronomic efficiency (NAE) is crucial for global food security, but its long-term changes and controlling factors under nitrogen (N) application are unknown. A meta-analysis of 477 studies found that overall NAE did not significantly change in the long term at the global scale, but a third of studies showed evidence of consistent directional changes in NAE over time. Annual precipitation played a key role in explaining the temporal trend of NAE.

Summary: With the rapid accumulation of plant trait data, there are major opportunities to integrate these data into predicting ecosystem primary productivity across different spatial extents. However, scaling up to the ecosystem scale has remained challenging. This study demonstrates the need to combine community-level traits and environmental factors to predict ecosystem productivity at landscape or biogeographic scales, and highlights the potential for integrating traits into ecological models to estimate productivity-related ecosystem functions and anticipate the response of terrestrial ecosystems to global change.

Summary: Tropical forests in the Anthropocene are subject to disturbances that create canopy gaps, affecting forest structure and function. This study investigated the effect of canopy gaps on seedlings from different successional stages in a tropical montane forest in China. Results showed that seedlings from early- and mid-successional stages had a greater growth response to increased light intensity under small and large canopy gaps compared to those from the late-successional stage. Light condition and specific leaf area were the most important factors influencing seedlings' relative growth rate across successional stages. The study highlights the distinct impact of disturbance-induced canopy gaps on seedling regeneration and emphasizes the potential detrimental effects on forest structure and successional trajectory.
