Summary: Anthropogenic nitrogen (N) enrichment in low-nutrient primary successional systems may affect plant community assembly and the dominance of ecosystem-engineering plants. The study examines the direct and interactive effects of microbial symbiosis and N addition on plant succession in Michigan, USA. The research finds that N addition suppresses plant diversity by reducing species richness when the symbiotic fungal endophyte Epichloe amarillans is present in the dominant dune grass species Ammophila breviligulata. N addition also alters plant community composition by favoring efficient colonizers, particularly C-4 grasses.

Summary: Despite reductions in nitrogen emissions in Europe over the past three decades, eutrophication remains a concern in the Baltic Sea basin. Recent modeling studies for the HELCOM Commission show that Germany, Poland, and Denmark are the major contributors to total nitrogen deposition in the Baltic Sea, with agriculture contributing most to reduced nitrogen and the transport sector contributing most to oxidized nitrogen deposition. Full compliance with the EU NEC Directive and the Gothenburg Protocol can lead to significant reductions in nitrogen deposition by 2030.

Summary: Hydrological regimes and climatic factors have complex influences on plant phenology in floodplain wetlands. Warmer temperature tends to advance the start of the pre-flooding growing season, while flood regimes play a dominant role in determining the phenology in the post-flooding growing season. Carex phenology is more affected by hydrology in high-elevation areas compared to low-elevation areas. These findings provide insights for the conservation and management of floodplain wetlands in the Yangtze River.

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: The study found that changes in vegetation composition in temperate forest understories are reflective of environmental changes caused by atmospheric nitrogen deposition and altered forest management, leading to a trend of eutrophication. Different forest types show varying sensitivity to these environmental changes, influenced by geological and climatic site characteristics as well as historical land use.

Summary: Terrestrial carbon storage is crucial for ecosystem services, with human-induced disturbances impacting present-day carbon stores. Regional and national quantification of carbon cycling is necessary to inform sustainable land use policy. This study in the UK shows a net increase in terrestrial carbon storage, but warns of potential challenges in maintaining this trend due to various factors such as nitrogen deposition and changing nutrient cycles.

Summary: Massive blooms of cyanobacteria regularly occur in the Baltic Sea during late summer, which can negatively impact water quality. Understanding the controls on cyanobacteria blooms is crucial for better management efforts. By combining satellite data, ocean circulation models, and nutrient observations, this study identifies offshore, nutrient-depleted areas as the primary origins of blooms.

Summary: N deposition in China's forests has led to soil acidification, with NHx deposition dominating in 80% of the area and NOy deposition dominating in South China. The contribution of NOy has been increasing over the years, while the contribution of NHx has been higher but decreasing. Soil acidification is influenced by the ratio of NHx to NOy, as NOy has a higher net proton production due to leaching in the form of NO3-. This research is important for policymaking and emphasizes the need to consider the synergistic effect of R-NHx/NOy changes to alleviate soil acidification.

Summary: Tidal salt marshes are highly efficient carbon sinks, but their potential for mitigating global warming remains uncertain due to inadequate sampling, inaccurate area estimations, and inappropriate dating methods. This study provides the first estimates of organic carbon storage and accumulation rates in salt marshes along the Pacific coast of Canada, revealing relatively low carbon stocks but higher accumulation rates compared to global averages, with significant variations between high and low marsh habitats.

Summary: This study investigates the impact of climate-induced changes in vegetation on hydrology and environment in the Jialing River Basin. The results show that climate change will cause increased runoff and nitrogen losses, and decreased sediment discharge and phosphorus losses in the basin. The changes in vegetation, predicted to be promoted by climate change, will have significant effects on the basin. The models used in this study provide useful information for formulating management measures.

Summary: This study examines the interactions of climate warming, elevated N deposition, and vegetation composition change on the carbon sink function of peatlands. The results show that vegetation composition plays a crucial role in regulating net CO2 flux in peatlands. If peatlands shift to shrub-dominated ecosystems, the net CO2 uptake would decrease under climate warming and elevated N deposition. However, if peatlands shift to graminoid-dominated ecosystems, the net CO2 uptake would be unaffected by climate warming and elevated N deposition.

Summary: In biogeomorphic landscapes, plants can influence landscape development through feedback interactions. Different clonal expansion strategies by landscape-forming plants under different sediment conditions can lead to varying landscape organizations. Plasticity in expansion strategy allows plants to optimize their engineering ability based on physical landscape conditions, as demonstrated in this study.

The standalone effect of insecticide exposure decreased the Odonata community, while nymphs decreased synergistically with temperature rise in paddy water. However, the impacts of each stressor alone varied among species.

Summary: The Arctic region is facing contamination from long-range pollution and local human activities. Polycyclic Aromatic Hydrocarbons (PAHs) are used as environmental indicators for emission, transport, and deposition processes. Research conducted in the Arctic surface snow in Ny-Ålesund, Svalbard from October 2018 to May 2019 shows that long-range inputs of PAHs mainly occur in winter, while the most abundant analyte retene exhibits opposite seasonal trends.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.

Summary: This study investigates the impact of biochar on methylmercury (MeHg) accumulation in rice. The results show that biochar reduces MeHg levels in paddy soils by decreasing bioavailable Hg and microbial Hg methylation. Additionally, biochar decreases the uptake and translocation of MeHg in rice plants, resulting in a reduction of MeHg accumulation in rice grains.

Summary: This study aims to explore the effects of thiencarbazone-methyl center dot isoxaflutole on soil microflora and the potential mitigation mechanisms to bacterial communities. It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
