Summary: Soil enzymes play a crucial role in mediating ecosystems' responses to environmental drivers. Understanding their sensitivity to global change drivers can help predict future scenarios and design tailored interventions. However, assessing the interactions between different drivers remains a challenge, as the direct, indirect, and combined effects need to be disentangled. This review examines the effects of global change drivers on soil enzyme activities and identifies knowledge gaps and challenges for future research and biomanipulation techniques. The overall increase in soil enzyme activities and biogeochemical cycles will continue, but factors like shifts in microbial communities and changes in carbon use efficiency can cause inflection points.

Summary: The analysis of phospholipid fatty acids (PLFAs) is a common method to quantify soil microbial abundance and analyze community structure. This study validates the quantitative sensitivity of complete neutral lipid (NLFA) and glycolipid fatty acid (GLFA) profiles in PLFA extraction method. The study finds that fatty acid markers show consistent taxonomic specificities across the three lipid fractions. Fatty acid profiles from soil extracts exhibit stronger differences between PLFAs, NLFAs, and GLFAs, indicating their different community properties. The concomitant measurement of fatty acid profiles from all three lipid fractions is a low-cost and potentially information-rich addition to the PLFA method.

Summary: Both soil microbial legacy (SML) and atmospheric nitrogen (N) deposition have significant effects on the performance of dominant grass and the abundance of N-cycling functional genes (NCFGs). Soil sterilization has been shown to improve the growth of dominant grass, while N addition only had an effect in sterilized soils. These findings highlight the importance of considering SML in assessing the effects of N deposition on plant performance and NCFGs in grassland vegetation succession.

Summary: By analyzing soil microbial biomass and composition, we determined the appropriate rate of straw return and nitrogen fertilizer use for maintaining soil ecosystem health. A combination of 50% straw return and 450 or 540 kg N ha(-1) yr(-1) effectively increased soil nutrient availability. However, 100% straw return with 450 kg N ha(-1) yr(-1) was not beneficial for soil ecosystem stability. In the treatments with 100% straw return and higher N fertilizer application (>450 kg ha(-1) yr(-1)), certain saprophytic fungi and pathogens became dominant fungal genera.

Summary: Nitrogen deposition can influence soil nitrogen and carbon cycling processes, but there is no consensus on how it affects carbon and nitrogen mineralization. This study investigated the effects of nitrogen addition on soil organic carbon and nitrogen mineralization beneath Haloxylon ammodendron shrubs in a temperate desert. The results showed that nitrogen addition increased soil nitrogen mineralization and nitrification rates, as well as carbon mineralization between shrubs. However, carbon mineralization beneath shrubs decreased. Nitrogen addition also affected soil microbial biomass carbon and nitrogen, with an increase between shrubs and a decrease beneath shrubs.

Summary: Research found that forest soil microorganisms acclimate to temperature variations by changing the lipid composition of their cell membranes. Saturated fatty acids increase while unsaturated fatty acids decrease with increasing temperature. The long-term warming may result in larger alterations in lipid constitute of soil microbial membranes compared to short-term incubation temperature gradient.

Summary: Global change factors like nitrogen deposition and precipitation reduction have significant impacts on terrestrial ecosystems, affecting both aboveground and underground processes. This study found that both nitrogen addition and precipitation reduction caused changes in the composition of soil nematode communities, with nitrogen addition having a more severe negative effect compared to precipitation reduction. Additionally, nitrogen addition and precipitation reduction had a synergistic effect on soil nematode communities.

Summary: This study used 16S rRNA gene amplicon sequencing to quantify the composition, spatial distribution, and assembly mechanisms of bacterial communities in the sediment of land-based shrimp ponds along the southeastern coastal zone of China. Results showed that the similarity of bacterial communities decreased with spatial distance and their variation was mainly attributed to deterministic (environmental filtering) processes. The balance between stochastic and deterministic assembly processes of bacterial communities was regulated by sediment sulfate concentrations.

Summary: The unprecedented warming in recent decades has led to delayed autumn leaf senescence dates in the Northern Hemisphere. This study shows that changes in soil moisture have a significant impact on autumn leaf senescence, surpassing the effects of temperature, precipitation, and radiation. A new model, CDDSM, based on soil-moisture-constrained cooling degree days, outperforms other models in predicting leaf senescence dates, especially in arid and semi-arid regions. The study also reveals that predicted leaf senescence dates under future climate change scenarios are earlier than other models.

Summary: Climate change has a global impact on soil microbial community composition in various ecosystems. However, the effects of warming on soil microbial community structure and the underlying mechanisms in subtropical forest ecosystems remain poorly understood. To fill this research gap, an altitudinal gradient was used to simulate ecosystem warming, and after 6 years, it was found that microbial co-occurrence network complexity increased with warming. The taxonomic composition changes were asynchronous, likely due to different community assembly processes. Stochastic processes drove bacterial community composition, but warming led to a shift from stochastic to deterministic drivers during the dry season.

Summary: This study aimed to assess the effects of soil fauna density and diversity on litter decomposition. The results showed that the presence of soil fauna significantly increased the rate of litter decomposition, and that the effects were mainly controlled by initial litter concentrations of phosphorus and magnesium. Soil fauna in litterbags had significant effects on litter decomposition, while ambient communities had limited effects.

Summary: With a fast changing climate and the rise of human population there is an increasing concern on food security whilst avoiding environmental damage. The beneficial effects of crop rotation and enhanced sown agro-diversity on yield production and ecosystem functioning have been demonstrated, although their persistence over time and our ability to detect such lasting legacy effects on the following crops have been barely investigated, thus hindering their adoption as an economically sustainable and ecologically sound solution. Biodiversity-ecosystem function relationships may result in lasting legacy effects leading to enhanced crop performance with increasing agrodiversity. Lower amounts of fertilizer may be needed by increasing the sown diversity during crop rotation, whose effects can be easily scaled-up and monitored by UAV and remote sensing tools.

Summary: There is increasing evidence that soil nutrient availability can limit forest carbon sink capacity, especially in the tropics where a large proportion of Earth's plant biomass is stored. This study analyzed stem growth and foliar elemental composition to assess the limitations of soil nutrients on tropical forest growth, with a focus on nitrogen and phosphorus limitations. Results showed a positive effect of nitrogen and phosphorus fertilization on stem growth and foliar nutrient concentrations, with potential nitrogen-fixing species exhibiting greater growth and nutrient concentrations compared to non-nitrogen-fixers.

Summary: The Biogeochemical niche hypothesis examines the relationship between species/genotype elemental composition and their ecological niche. This study analyzed the foliar elemental concentrations and functional-morphological traits of 60 tree species in a French Guiana tropical forest, providing empirical evidence for a relationship between species-specific leaf element composition and functional traits. The study supports the hypothesis of species-specific use of bio-elements driving niche segregation and high levels of alpha-diversity in this tropical forest.

Summary: The stability of ANPP in alpine meadow is affected by precipitation fluctuations, especially extreme precipitation. Normal interannual fluctuations in precipitation and recent changes in regional precipitation have little effect on ANPP stability, but extreme precipitation significantly reduces ANPP, species asynchrony, and ANPP stability. ANPP stability is directly influenced by population stability, species asynchrony, and grass stability, while the effect of species diversity on ANPP stability depends on its impact on species asynchrony and population stability. Dominant species stability indirectly affects ANPP stability by altering species asynchrony.

Summary: Plants have evolved complex mechanisms to produce defense secondary metabolites (SMs) to cope with environmental stress. However, these mechanisms are not well studied in mature trees, limiting our understanding of climate change effects. We investigated SMs and their relations to growth, carbohydrates, and phytohormones in a Mediterranean forest dominated by two tree species. Our results showed seasonality of leaf SMs and reduced SMs and sugars in the drought-resistant species P. latifolia during experimental drought. The drought-susceptible species Q. ilex had lower and constant levels of SMs, regardless of drought. We found differences in phytohormones and growth between the two species. Our study suggests that defense SMs in mature trees are regulated by phytohormones and carbohydrates, and P. latifolia may become more vulnerable to stress in a drying climate due to reduced defense SMs and carbohydrates in stem phloem.

Summary: Our study suggests that plastic film mulching and its residues in croplands do not pose a significant threat to food security, as the positive effects of the mulching practice outweigh any potential negative impacts. Although long-term use of plastic film mulching and urea nitrogen fertilization may have detrimental effects on crop growth, our experiment found no substantial differences in soil properties, maize growth, and yield between previously mulched and never-mulched plots.
