Summary: A study conducted in southwest Germany found that nitrogen deposition had a lesser impact on explaining vegetation gradients in forest ecosystems compared to other site factors such as soil C/N ratio, soil pH, and canopy cover. The effects of nitrogen deposition on species richness, nitrophyte cover, and sensitive character species cover varied depending on the deposition model used and the forest types examined. The study highlights the importance of considering contextual dependency when evaluating the effects of nitrogen deposition in forests.

Summary: "Studies have shown that a portion of both wet and dry N deposition can be retained within the canopy, absorbed by leaves or other aerial parts, and utilized for plant metabolism, significantly altering the fate of N in the ecosystem. The canopy-associated biota play an active role in various processes of the N cycle, such as nitrification, fixation, and volatilization."

Summary: The fate of atmospheric nitrogen (N) deposition in forest ecosystems is influenced by the role of tree canopy in intercepting, transforming, and assimilating N inputs. This study simulated increased N deposition using two contrasting fertilization strategies, above-canopy and below-canopy, in a sessile oak stand. The results showed that above-canopy fertilization led to higher recovery of fertilizer in plants, while below-canopy fertilization resulted in greater retention of fertilizer in the litter layer and higher recovery in wood and fine roots. The findings highlight the importance of the forest canopy in intercepting atmospheric N deposition in broadleaved forests.

Summary: Global vegetation regimes have different dynamics in belowground carbon (C) and nitrogen (N), but it is challenging to separate large-scale climatic controls from intrinsic plant-soil-microbial feedback effects. In local gradients with similar pedo-climatic conditions, the effects of plant-microbial feedbacks can be isolated from large-scale drivers. In a subarctic-alpine mosaic, contrasting plant-microbial feedbacks contribute to diverging soil C : N ratios at the landscape scale.

Summary: Increasing nitrogen deposition leads to linear increases in total N2O (N2OT) and nitrification-derived N2O (N2On) emissions, but linear decreases in denitrification-derived N2O (N2Od) emissions at different soil depths. N2On emissions are positively correlated with the proportion of N2On emitted from nitrification, while N2Od emissions are positively correlated with the abundance of narG and nirS genes. These findings provide insight into the mechanisms of N2OT emissions and emphasize the importance of considering different N transformation processes in predicting N2OT emissions in the context of enhanced N deposition.

Summary: The atmospheric nitrogen deposition in the Chesapeake Bay watershed has been an important focus of research as a nutrient source and driver of estuarine trophic status. Historical data shows that the proportion of atmospheric nitrogen deposition in the watershed increased from 30% in 1950 to a peak of 40% in 1973, and then declined to 28% by 2015. This highlights the significant role of atmospheric nitrogen deposition in the Chesapeake Bay watershed and the potential for reducing deposition to improve water quality.

Summary: This study reveals significant relationships between fine root endophyte mycorrhizal fungi and soil variables such as S, P, C:N ratio, electrical conductivity, and manganese (Mn). It also highlights the negative relationship between estimated nitrogen deposition and the colonization of mycorrhizal fungi. The research identifies a greater diversity of Endogonales operational taxonomic units (OTUs) in the roots of Lycopodiella inundata and shows that OTU richness correlates negatively with soil C:N ratio while community composition is mainly influenced by soil P. These findings suggest that fine root endophyte mycorrhizal fungi have distinct ecological preferences in response to edaphic variables and air pollution.

Summary: Human activities are enriching many of Earth's ecosystems with biologically limiting mineral nutrients such as nitrogen (N) and phosphorus (P), which generally reduce plant diversity and increase productivity in grasslands. Short-term nutrient addition can increase aboveground live biomass and reduce plant diversity, but the long-term effects of nutrient enrichment on global grassland ecosystems may be underestimated.

Summary: Assessing the impacts of atmospheric nitrogen (N) deposition on ecosystems and biodiversity through large-scale spatial gradients is crucial, but it comes with challenges such as biased confidence intervals and false positive results. The re-analysis of previous datasets in Britain by Pescott & Jitlal (2020) revealed weaker N deposition effects, suggesting that previous estimates may have been overestimated. Further research is needed to determine the accuracy and potential measurement errors of the N deposition covariate in order to draw reliable conclusions.

Summary: This study explores the impact of above- and belowground beta-diversity on spatial turnover of grassland ecosystem functions, revealing that the effects of abiotic factors on turnover are largely indirect through their influences on beta-diversity. It is found that spatial turnover of ecosystem function is more strongly associated with plant beta-diversity than with soil microbial beta-diversity. These results suggest that changes in above- and belowground species composition play a key role in determining variability in multiple ecosystem functions across spatial scales.

Summary: Fertilisation experiments have shown that nutrient availability plays a crucial role in grassland biomass production and carbon sequestration. This study, based on a global dataset, found that soil micronutrients, particularly Zn and Fe, along with other soil factors, were key predictors of biomass variation. However, the association between micronutrients and biomass was absent in grasslands limited by NP, highlighting the significance of co-limitation by NP and micronutrients.

Summary: Nutrients and herbivores have separate effects on aboveground biomass stability in grasslands, with nutrient addition increasing community composition changes over time and herbivore exclusion decreasing spatial asynchrony. However, their interaction has a weak positive effect on stability by increasing spatial asynchrony. Understanding the processes operating at different spatial scales can contribute to the conservation and management of ecosystems.

Summary: Ancient semi-natural grasslands in Europe are crucial for providing ecosystem services, and Grassland Green Infrastructure (GGI) surrounding these grasslands can supplement the provision of these services. A study investigated the potential of GGI to deliver various ecosystem services, concluding that GGI had lower delivery for conservation, pollination, and aesthetic appeal, but not for carbon storage. These differences were attributed to fewer plant species and compositional differences in GGI compared to the core grasslands. Improved management of GGI can enhance landscape-wide delivery of nature conservation value and pollination.

Summary: In recent years, global efforts have been made to restore former grassland sites in order to address the loss of ancient species-rich grasslands and protect grassland biodiversity. This study examined how plant species spontaneously colonize restored grasslands in a small-scale setting. The results showed that grazing activity and distance to adjacent grassland influenced species richness and vegetation cover. Forest-associated plant species declined, while generalist species and some grassland specialists increased. However, not all grassland specialists successfully colonized the restored grasslands and the colonization pattern varied over time. The presence of grazing livestock, continuous seed arrival, and disturbance are crucial for successful colonization and establishment of plant species.

Summary: Before the mid-20th century, there was a lack of concrete knowledge about floristic change in Britain. In this article, the authors demonstrate how advanced computational-linguistic and historical-geographic information systems techniques can efficiently collate and analyze disparate historical sources to study the floristic history of the English Lake District. By integrating natural language processing techniques with Kew's Plants of the World Online database, temporal shifts in plant-naming conventions across texts published between 1682 and 1904 can be more accurately traced. Through collocate analysis and automated geoparsing techniques, geographies associated with plant names are identified and extracted for potential geo-temporal analysis.

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.
