Summary: Soil nutrient availability and aggregate fractions affect the concentrations of soil microbial residues and their contribution to SOC accumulation in tropical coastal forests. Continuous phosphorus addition decreases microbial residues and their contribution to SOC, while nitrogen addition has little effect. The mechanisms driving microbial residue responses to increased N and P availability may differ, with P-induced reductions potentially impacting SOC stability in N-rich and P-poor tropical forests.

Summary: Honey is a valuable sweetener worldwide, but it is often adulterated with sugar syrups, affecting its nutritive value. This study used various analytical techniques to authenticate honey samples in Lebanon, revealing distinct delta C-13 values for authentic and adulterated samples. LC-C-IRMS techniques can provide additional information on the authenticity of honey by analyzing the delta C-13 of individual sugars.

Summary: The use of biochar as a soil amendment has the potential to enhance soil quality and carbon sequestration. However, the effects of biochar on soil microbial residues in soil aggregates are not well understood. This study found that the addition of chemical fertilizer significantly increased the levels of microbial residues, and the combined application of biochar with chemical fertilizer was more effective at increasing the accumulation of microbial residues in soil aggregates.

Summary: Microbial biomass residues play an important role in biogeochemical cycling, but the mechanism by which they are sequestered in soil organic matter remains elusive. This study revealed that bacterial biomass is predominantly utilized by fungi and stabilized as fungal necromass, contributing to soil organic carbon sequestration. The study also identified three phases in the metabolism of microbial biomass residues, with the final phase focused on C preservation rather than energy production.

Summary: Phosphorus (P) is an essential nutrient that greatly affects soil organic carbon (SOC) dynamics. However, the response of amino sugars, an essential component of SOC, to P addition in China remains unclear. In a meta-analysis of 24 observations from nine research publications, we found that P addition significantly increased the necromass of total microbial, fungal, and bacterial communities. The effects of P addition on amino sugars varied depending on climate, ecosystem type, P addition rate, and duration. Our findings have important implications for soil fertility enhancement and SOC sequestration.

Summary: Nitrogen deposition can affect carbon dynamics and storage in tropical soils by altering the transformation of plant litter carbon to soil organic carbon. In this study, long-term nitrogen addition was found to increase fungal community diversity and accelerate decomposition of recalcitrant litter carbon compounds, leading to an increase in soil organic carbon.

Summary: This study investigated the amino acid and sugar composition of conventional polyfloral honey and bumblebee honey. Proline was found to be the main amino acid in both types of honey. Buckwheat honey had the highest concentration of essential amino acids, while bumblebee honey had higher concentrations of certain individual amino acids compared to honeybee polyfloral honey.

Summary: The study demonstrated the fate of the bacterial storage compound poly-beta-hydroxybutyrate (PHB) in crustaceans, showing that C-13 signal may partly come from the structural components of bacterial cell. There was lower C-13 enrichment in various lipid fractions of the postlarvae compared to the diet, indicating potential of PHB as an energy source rather than a building block. Rapid assimilation of PHB in crustacean tissues was observed, suggesting its role as an energy source.

Summary: The understanding of soil organic matter (SOM) dynamics has advanced significantly in recent years, shifting from the belief that most SOM consists of recalcitrant compounds to the view that it is a range of polymers continuously processed into smaller molecules by decomposer enzymes. The proposed C-STABILITY model combines compartmental and continuous modeling approaches to accurately reproduce SOM cycling processes, emphasizing the influence of substrate accessibility on SOM turnover. The model also considers enzymatic and microbial biotransformations of substrate, providing new insights on how depolymerization and decomposers ecology impact organic matter chemistry and amount during decomposition and at steady state.

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: The study investigated soil fluxes of CO2, CH4, and N2O in four tropical forest sites in northern Ecuador. Results showed an unusual increase in CO2 emissions at high altitude, a consistent atmospheric CH4 sink, and a transition from a net N2O source to sink along the altitudinal gradient. The findings provide arguments and insights for future studies on tropical montane forests.

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: Maize genotypes directly affect gene expression and nitrogen uptake capacity. The feedback between maize genotypes and soil nitrogen transformations, as well as their regulations on nitrogen uptake capacity, have been studied. The findings suggest that maize genotypes play a central role in regulating these feedbacks, which are important for maize breeding and enhancing maize production.

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.
