Summary: In this study, the effects of precommercial thinning on soil organic carbon (SOC) and carbon cycling-related enzyme activities were examined. Thinning significantly reduced SOC levels, but as time progressed, SOC gradually recovered to the unthinned level. Thinning also led to changes in carbon cycling-related enzyme activities and soil water content. These findings provide important scientific insights into the response of SOC to forest thinning.

Summary: The ratio of beta-1,4-glucosidase (BG) activity to phosphomonoesterase (PME) activity is an indicator of microbial phosphorus (P) demand. Comparing with other soils, tropical soils have higher microbial P demand and fertilization can partly satisfy this demand. The usage of BG:PME ratio as an indicator of microbial P demand may overestimate P shortages in tropical soils.

Summary: The aim of this study was to investigate the effects of poplar-intercropping systems on soil nutrients and soil enzyme activities, as well as to analyze the relationship between soil enzyme activities and soil nutrients. The results showed that the intercropping systems had higher concentrations of soil organic matter, total nitrogen, total phosphorus, total potassium, available nitrogen, available phosphorus, available potassium, and four soil enzyme activities compared to monoculture wheat systems. The distribution of soil nutrients and enzyme activities varied with soil depth and distance from the poplar row. Comparatively, the reasonably dense planting of intercropped poplar had more obvious effects on improving soil enzyme activities and soil nutrients.

Summary: This study investigated the temporal variation of soil extracellular enzyme (EE) activity in a tropical terra-firme forest. Results showed that EE activity peaked during the drier season, associated with increased leaf litterfall and negatively correlated with precipitation. Soil nutrients were weakly related to EE activity, but extractable N was related in the top 5 cm of soil. The study suggests that EE activity is synchronized with precipitation-driven substrate inputs and depends on the availability of N, with dynamic shifts in microbial activity in response to climate seasonality and resource limitation.

Summary: The priming effect (PE) is a key mechanism contributing to the carbon balance of the soil ecosystem. Recent research has shown increased interest in understanding and studying this mechanism. Although there are still gaps in knowledge, progress has been made in deciphering the non-biological mechanisms underlying PE and identifying the microbial actors involved. However, including PE into mechanistic models remains challenging as the mechanisms are not fully understood.

Summary: In this study, we investigated the decay type of large-diameter aspen, birch, and pine logs in eight climatically-distinct forest sites in the United States. Our results showed that white rot fungi were the most dominant and diverse wood-rotting fungal guild, and soft rot fungi were more abundant than brown rot fungi. The decay type was influenced by both biotic and abiotic factors, varying among different tree species.

Summary: Previous studies have shown that tree species diversity can enhance forest productivity and nutrient cycling. However, the effects of mixing tree species on stand-level nutrient use efficiency (NutUE) have been rarely studied, especially in the context of climate change. This study examines how the effects of species diversity on NutUE are modified by water availability and drought conditions. The results suggest that species composition of tree mixtures is more important than water availability for stand-level NutUE in young forest communities.

Summary: This study quantified the distribution of nitrogen, dry-matter, and soil-applied (15)N in different compartments of five naturally-growing oak trees. The results showed that the xylem rings compartment contained the most biomass, while branches and coarse roots contained the most nitrogen. The labeled (15)N was found in all compartments except the heartwood, with the majority being in the leaves. Overlooked compartments such as coarse roots, stumps, xylem, and other branches accounted for a significant portion of the (15)N recovery. The study also revealed that (15)N was present in all sapwood rings, with more being found in younger rings compared to older ones. The (15)N allocated to ancient rings could originate from various sources, including direct uptake from the soil, autumnal resorption from leaves, or transport through ray parenchyma. Additionally, the study confirmed the role of microbial biomass as a nitrogen sink in forests.

Summary: This study investigates the effects of phosphorus fertilisation, understory removal, and their interaction on carbon storage and soil enzyme activities in two moorlands planted with maritime pines. Results show that in wet moorlands, fertilisation and understory removal have a positive effect on tree biomass, but do not affect soil carbon stocks or enzyme activities. In dry moorlands, understory removal has a positive effect on tree biomass but decreases topsoil organic carbon stocks and enzyme activities. Overall, the study highlights the importance of adapting forest practices based on environmental context and carbon sequestration objectives.

Summary: Litter decomposition is influenced by the energy and nutrient acquisition ability of decomposer communities. This study showed that the stoichiometric imbalance between soil microorganisms and litter substrates directly controls decomposition rates in the early phase, while the imbalance between soil microorganisms and soil substrates indirectly regulates decomposition rates in the later phase through shifts in fungal community composition and enzyme allocation.

Summary: This study examined the interactive effects of soil water availability and tree species composition on soil organic nitrogen cycling processes. It was found that high soil water availability increased soil protein depolymerisation rates, but tree species composition had no effect on these processes. When considering the interaction between tree species mixing and soil water availability, it was found that tree species mixing had a negative effect on soil organic nitrogen cycling processes under dry conditions, but this effect became positive under higher water availability.

Summary: Biodiversity loss has a significant impact on ecosystem functions, and it is necessary to quantify the relationship between biodiversity and ecosystem functions (BEF). This review proposes a new BEF model based on species interaction networks and finds that it provides better results than other common fitting methods. The model reveals scale dependence and nonlinear changes in the relationship between biodiversity and ecosystem functions, highlighting the importance of considering interactions among species. The model can be used as an alternative approach to estimate BEF and guide conservation efforts worldwide.

Summary: Soil microbial community coalescence, the mixing and interaction of microbial communities, has been found to enhance the stability and complexity of rhizobacterial networks, leading to improved plant health and biomass. This study investigated the effects of different degrees of bacterial community coalescence on plant disease resistance by mixing soils from healthy and diseased habitats for watermelon planting. The results showed that mixing in more healthy soil reduced the plant disease index and increased biomass by improving the stability and complexity of the rhizobacterial network. Core taxa Nitrospirillum and Singulisphaera were enriched in the rhizosphere from healthy soils and played important roles in disease suppression and regulating the positive cohesion and modularity of the networks. Overall, these findings provide insights into the potential mechanism of microbial community coalescence for improving plant microbial community function and suggest new tools for enhancing plant fitness via soil microbiota mixing.

Summary: Collembolans, the diverse group of soil invertebrates, are affected by anthropogenic climate warming, which alters their diversity and density. In addition to abiotic stressors, changes in food availability, specifically the abundance of saprotrophic and mycorrhizal fungi, influence Collembola responses to climate warming. Collembolans prefer saprotrophic fungi but rely on mycorrhizal fungi when food sources are scarce. Understanding the mechanisms behind these dietary shifts in warm-dry and warm-wet soil conditions is crucial for predicting the impact of climate change on Collembola-fungal interactions.
