Summary: Research has shown that trace metals can be toxic, but current studies mainly focus on single organisms rather than multi-trophic transfer in terrestrial food chains. The key factors controlling the transfer of trace metals in the soil-plant-arthropod system are found to be the form and location of the metal, as well as the physiological mechanisms of each organism.

Summary: Nitrogen deposition can promote aboveground net primary productivity (ANPP) but may decrease plant richness. The sensitivity of plant communities to precipitation is influenced by seasonal nitrogen additions, with precipitation being the primary limiting factor in the semiarid grassland. Multi-season nitrogen addition is required to accurately assess ecosystem responses.

Summary: Sulphur deposition through rainfall has caused species loss and ecosystem degradation globally. This study analyzes data from thousands of sites across Great Britain and finds that reductions in sulphur emissions have led to gradual recovery of acidified ecosystems in low-intensity habitats, but not in high-intensity habitats. Nitrogen deposition has no additional effect on soil acidity once sulphur deposition is accounted for.

Summary: Ecological theory and empirical evidence suggest that greater structural complexity and diversity in plant communities enhances arthropod abundance and diversity. However, nonnative plants, which lack evolutionary history, are typically associated with low arthropod abundance and diversity. This study examines urban forests to determine whether structural complexity associated with nonnative plants will increase or decrease arthropod abundance and diversity.

Summary: This study synthesizes data sets on organic matter, microbes, and macroinvertebrates from two detritus-based stream ecosystems, providing new insights into carbon flow through forest stream ecosystems. It found a balance of carbon inputs and outputs in the reference stream, while nitrogen and phosphorus enrichment led to severe deficits of carbon. The results highlight the key roles of both microbes and metazoans in controlling carbon flow in detritus-based ecosystems.

Summary: This article discusses the challenges posed by droughts, wildfires, and windstorms on the adaptability of forest arthropod communities, as well as the influence of disturbance legacies on these communities. The authors highlight the various disturbance legacies and their effects, such as surviving arthropods, micro-environmental legacies, and resources related to trees and the ground. They also emphasize the need for further research on how disturbance legacies impact forest arthropod communities.

Summary: This study analyzed data from 290 vegetation communities worldwide and found that there are more N-fixing vascular plants in dry climates and in communities where biomass is removed through management methods. In dry climates, abundant light and biomass removal provide a competitive advantage to light-demanding N-fixers. Although there was a slight increase in global occurrence of N-fixers from 1906 to 2018, there were no other significant temporal trends.

Summary: The distribution of multi-trophic microbiota in river confluences is determined by both deterministic and stochastic processes, and the response of higher trophic levels to environmental factors is more intense than that of lower trophic microbiota. Flow velocity plays a crucial role in controlling the assembly and composition of multi-trophic microbiota and has a significant impact on nitrogen dynamics.

Summary: Increased nitrogen deposition and changes in precipitation patterns have significant impacts on soil microbial communities in tropical/subtropical forests, particularly on fungal communities. The effects of these environmental changes are more prominent in the dry season and have important consequences for soil processes and ecosystem functions.

Summary: Dryland ecosystems have a threshold of herbaceous productivity for the coexistence of biocrusts and vascular plants, with biocrusts unable to coexist with perennial herbs when the threshold is exceeded.

Summary: The effect of plant communities on nitrogen cycling and N2O fluxes under flooding conditions was investigated. Mixing grasses with legumes reduced nitrogen losses and enhanced plant nitrogen uptake in flooded conditions. However, the presence of legumes increased N2O fluxes due to increased soil nitrate availability.

Summary: Accurate trophic discrimination factors (TDF) are necessary for robustly quantifying dietary resource use and trophic position using stable isotopes. Previous studies suggested TDF values of around 1.0 for & UDelta;C-13 and 3.4 for & UDelta;N-15, but recent research indicates that these values may be more nuanced. The relative importance of different factors, such as taxa, tissues, trophic level, and diets, is still unclear.

Summary: Windstorms and salvage logging have significant impacts on soil-living arthropod communities in alpine spruce forests. This study used DNA metabarcoding to investigate the effects of wind-induced disturbances on these communities, revealing a decrease in abundance and richness of microarthropods in windfall sites. The species composition and functional guilds of microarthropods were also found to be different between disturbed and undisturbed forests. The study highlights the importance of considering environmental gradients in understanding the responses of arthropod communities to forest disturbance.

Summary: A study using a 14-year dataset from Greenland shows that an increase in temperature led to a halving of arthropod species richness, and considering species interactions improves predictive models considerably. Cascading trophic effects play a crucial role in structuring biodiversity response to climate change, representing a major step forward for predictive ecology.

Summary: Plant quantity and quality can independently influence the richness and abundance of arthropod communities. Changes in plant productivity and leaf traits can alter arthropod diversity and affect multiple functions in terrestrial ecosystems. Different arthropod orders exhibit specific responses to variations in plant quantity or quality, reflecting their diverse food requirements and feeding behaviors.

Summary: The study found that under conditions of low-level nitrogen deposition, the arthropod assemblage of big sagebrush responded to nitrogen enrichment, primarily due to an increase in the number of aphids that have mutualistic relationships with predatory ants. Non-mutualist predators were rare in the N treatment plots, indicating that ants provided better anti-predator protection for mutualistic herbivores.
