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: This study conducted a decomposition experiment across four successional stages to investigate the dynamics and mechanisms of litter decomposition and soil organic carbon (SOC) sequestration following vegetation succession. The results showed that litter decomposition rates decreased gradually with vegetation succession, and litter quality was the major factor controlling the decomposition rate. The early successional stage had higher rates of litter decomposition and SOC turnover, while the late successional stage showed lower rates. Litter inputs significantly increased SOC content in the early stage, but soil carbon sequestration reached saturation in the late stage.

Summary: Bioturbation plays a crucial role in maintaining the physicochemical properties of freshwater ecosystems. It influences the flow of nutrients and particles in the sediment-water interface through the activities of biotic components. Benthic macroinvertebrates, with their abundance and activities, have a significant impact on sediment and water profile. Their bioturbation activities result in modified sediment architecture, changed redox potential, and nutrient fluxes. They also affect the deposition of organic matter, remobilization of pollutants, and composition of microbial communities. As ecosystem engineers, benthic macroinvertebrates play multiple functional roles in sustaining and stabilizing freshwater systems.

Summary: The aim of this research was to determine the factors that have the greatest influence on the C, N and P cycles in the deadwood-soil system in mountain forest ecosystems. The study found that the climatic conditions resulting from altitude and decomposition rate are the strongest determinants of C/N/P stoichiometry. The research used spruce logs at different decomposition stages in Babiogorski National Park, Poland, and found that high elevation significantly shapes the C, N and P content. There was a strong correlation between P content, N content and C/N ratio. The study highlights the importance of leaving deadwood in forest ecosystems to improve biogeochemical cycles and enhance biodiversity and stability.

Summary: While the relationship between taxonomic diversity and ecosystem function is well-studied, the impact of deeper dimensions of biodiversity on important processes is not well-understood. This study aimed to determine the role of these dimensions in carbon processing in rivers by examining riparian forest community structure and leaf litter diversity. Experimental manipulations in three headwater streams were carried out to investigate the contributions of taxonomic, functional, and phylogenetic diversity to decomposition rates in rivers. The results showed significant interspecific variation in breakdown rates among riparian tree species, and a positive relationship between breakdown rate and foliar tissue chemistries. Functional and phylogenetic diversity also influenced breakdown rates independently. These findings contribute to our understanding of the complex relationship between biodiversity and ecosystem function.

Summary: This study utilized various analytical methods to investigate the fluorescence behavior of modern phytoliths. The results revealed that the fluorescence of phytoliths is influenced by temperature and molecular structure. Organic compounds cause fluorescence at low temperatures, while molecular changes in phytolith silica induce fluorescence at high temperatures. The fluorescence is caused by clusterization-triggered emissions, which result from overlapping electron clouds forming non-conventional chromophores. Additionally, the extractable phytoliths were found to be dominated by lumen phytoliths.

Summary: Increased nutrient availability following permafrost thawing affects the biogeochemical cycling, greenhouse gas exchange, and nitrous oxide emissions in high Arctic ecosystems. However, there is a weak fertilization effect due to a mismatch between the timing of peak vegetative growth and peak thaw depth, resulting in incomplete plant use of nutrients near the permafrost table.

Summary: Water regimes in temperate grasslands affect plant silicon and nitrogen concentrations, with grasses showing more consistent silicon responses and forbs showing more variable responses. Drought increased nitrogen concentrations for all species, while waterlogging and flooding resulted in decreased concentrations for some species. Changes in water regimes influenced the rankings of plant silicon and nitrogen concentrations, particularly in forbs. The observed plasticity in plant silicon and nitrogen concentrations may have significant implications for ecological processes.

Summary: Despite previous studies focusing on Si supply and stress mitigation, the ecological significance of Si in plant biology and ecology remains understudied and challenging to capture. This paper highlights the high costs of Si accumulation and explores its potential links to fitness components, environment, and ecosystem functioning. The authors propose that Si may play a greater role in trait-based ecology than currently recognized, but knowledge gaps hinder understanding of its contribution to clade success and biome expansion.

Summary: Arctic soils are the largest reservoir of soil organic carbon in the world. Rising temperatures in the Arctic and increased freeze-thaw cycles have significant impacts on CO2 fluxes in Arctic soils. Our study demonstrates that each freeze-thaw cycle decreases CO2 fluxes, and reveals the presence of considerable CO2 emission below 0 degrees C. We also show that Si and Ca concentrations play central roles in controlling Arctic soil CO2 release. Our findings highlight the need for further research on freeze-thaw cycles and the effects of Ca and Si on carbon fluxes in high latitudes.

Summary: Several methods are used to determine silicon (Si) contents in plant materials, but none of them has become prevalent due to their advantages and drawbacks. Alkaline extraction using chemicals like sodium carbonate is widely used because it is simple and cheap. However, there is a lack of comprehensive comparison between different alkaline extractions and understanding of the relationship between Si content in plants and soil silicon availability. This study compared different alkaline extractions and found that Tiron was more efficient in extracting Si compared to sodium carbonate. Phytolith contents in plant samples were strongly correlated to Si contents obtained from extractions, especially in husk samples.

Summary: Increased crop production to feed the predicted human population is a main goal, but current management practices are not sustainable due to high fertilizer application and vulnerability to decreased soil water availability. Increasing soil C sequestration through single time fertilization with amorphous silicon (ASi) can potentially decrease greenhouse gas emissions. This study demonstrates how ASi fertilization affects crop yield and soil C sequestration in an agricultural system cultivating wheat, showing increased yield and biomass production as well as soil C uptake. This provides a new management strategy for sustainable crop production.

Summary: Rice cultivation in regions with elevated arsenic concentrations poses a health concern. Silicon and Si nanoparticles have potential in reducing arsenic accumulation, but their effectiveness is influenced by initial silicon levels in the soil and silicon introduced through fertilization. Low silicon additions may increase arsenic uptake, while higher silicon concentrations may alleviate arsenic uptake and toxicity. Silicate-solubilizing bacteria can enhance silicon availability and regulate the biogeochemical cycle, synergistically affecting arsenic resistance.
