Summary: Soil microbes play a crucial role in biogeochemical processes in forest ecosystems. Soil pH is an important factor that positively affects these processes. However, our study found weak and/or curvilinear relationships between soil pH and microbial biomass and activity, suggesting that plant-microbial interactions and other complexities may inhibit or mask microbial response to changes in pH.

Summary: This study examines the global patterns of soil microbial biomass and microbial stoichiometric ratios using a random forest model. The results show that concentrations of microbial biomass carbon (MBC), microbial biomass nitrogen (MBN), and microbial biomass phosphorus (MBP) are closely linked to soil organic carbon, while the stoichiometry of microbial biomass ratios is influenced by climatic factors. The study also reveals seasonal variations in MBC concentrations, with peaks in summer for tundra and boreal forests, and in autumn for subtropical and tropical biomes. The highest concentrations, stocks, and C/N/P ratios of microbial biomass are found in high latitude regions, likely due to higher soil organic matter content, greater fungal abundance, and lower nutrient availability. The findings provide important insights into carbon and nutrient cycling at a global scale, as well as for developing soil C-cycling models.

Summary: This study quantified fine root biomass and growth in a long-term fertilization experiment in northern hardwood forests. The results showed that increased soil nutrient availability did not result in a decline in fine root biomass or growth. Instead, fine root growth increased in response to nitrogen (N) addition. The differential growth response between above- and belowground components is a mechanism by which trees enhance phosphorus (P) acquisition in response to increasing N availability.

Summary: Functional balance theory suggests that plants allocate less carbon belowground when nutrient availability is high. In a nitrogen (N) x phosphorus (P) addition experiment conducted in two northern hardwood forest stands, we found that fine root biomass was higher in plots receiving P, and fine root growth was highest in plots receiving both N and P. This suggests that long-term addition of nutrients does not decrease belowground productivity. However, we did not observe conclusive evidence of nutrient foraging at different scales or specific responses to the addition of limiting nutrients. Our observations highlight the complex interactions of N and P in aboveground and belowground production in early successional northern hardwood forest ecosystems.

Summary: Long-term nitrogen enrichment in coniferous forests can enhance carbon retention in soil, but may also increase the demand for phosphorus. While nitrogen enrichment has been shown to reduce decomposition and increase carbon accumulation, its impact on microbial phosphorus mobilization and soil carbon storage remains uncertain.

Summary: The presence of European earthworms in Northern Maine forests could disrupt ecosystem dynamics by altering soil properties and reducing carbon stocks. Areas with earthworms had significantly lower soil carbon stocks, and management actions should be taken to prevent the introduction of earthworms into unaffected areas.

Summary: Long-term soil warming leads to changes in soil phosphorus pools and processes, resulting in decreased total phosphorus storage in the soil, increased sorption of recalcitrant phosphorus fractions, lower bioavailable phosphorus in the soil solution, and negative impacts on phosphorus limitation for trees and soil microbes, thus reducing the carbon sequestration potential of forests.

Summary: Nitrogen and phosphorus are crucial elements associated with the life history of organisms, and soil microbes play significant roles in nutrient cycling and ecosystem dynamics. This study analyzed microbial C, N, and P concentrations and ratios on a global scale, revealing variations within and across different ecosystems and spatial scales. The scaling exponent of microbial N versus P differed significantly across spatial scales, with soil total P identified as a key contributor to this variation.

Summary: This article explores the potential decline in resilience of global forest ecosystems due to disturbances. By analyzing data on multiple ecosystem state variables from the Hubbard Brook Experimental Forest in New Hampshire, USA, the study shows that around 60% of the early warning signals indicate decreasing resilience. These signals are important for assessing the health and development direction of forest ecosystems.

Summary: Skid trails and landings in managed forests can lead to soil disturbance and reduced methane (CH4) oxidation or emissions. During active harvesting, CH4 oxidation steadily declined, with small emissions by the end. A chronosequence of soil recovery found high CH4 emissions in the first year after harvest, followed by a decrease. By the end of a 15-year period, the soils had returned to acting as CH4 sinks, but with lower oxidation rates compared to undisturbed forests. Remediation measures should be implemented immediately after harvest to avoid high emissions and prioritize wood fragment removal or prevention.

Summary: Increasing atmospheric nitrogen (N) deposition can affect soil phosphorus (P) transformations, but the pathways and mechanisms are unclear. This study measured soil P fractions and biochemical properties in larch stands with long-term N addition in northern China. The results show that N addition influences soil P availability and fractions mainly through its effects on soil organic C and microbial properties.

Summary: This study investigated the soil factors influencing the development of biological denitrification inhibition (BDI) and found that initial soil moisture, ammonium concentration, and the initial abundance of certain microbial genes play significant roles in BDI development. Additionally, the research highlighted the relevance of biotic factors in explaining BDI and proposed the use of procyanidin concentration from plant belowground system as a new proxy for measuring BDI intensity.

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.
