Summary: Atmospheric nitrate and sulfate, major inorganic components of particulate matter, have a significant impact on human health, ecosystem health, and air quality. This study investigated the long-term response of particle chemistry in urban and rural environments in southern New England, an area historically affected by nitrogen oxides (NOx) and sulfur dioxide (SO2) emissions. The results showed that there was a significant urban-rural aerosol chemical composition gradient within a 40 km radius. As anthropogenic influences decreased, the relative contribution of marine and crustal sources increased, affecting the chemistry of fine and coarse particles. Total mass concentrations of chemical species, particularly anthropogenic sulfate and particulate ammonium, decreased dramatically over the ten-year period at both urban and rural sites. However, nitrate concentration increased despite significant reductions in NOx emissions, indicating changes in chemical mechanisms. Furthermore, the decrease in SO2 emissions significantly impacted the atmospheric lifetime and transport distance of particulate ammonium.

Summary: Understanding the primary emissions of sulfate, nitrate, and ammonium from solid fuel combustion is important for studying their role in haze formation. Through combustion experiments, the direct emissions of these ions from residential coal combustion and biomass burning were quantified. The emissions varied among different fuel types, with sulfate being the dominant ion. These findings suggest that primary emissions from coal combustion contribute significantly to atmospheric sulfate, especially in winter. The contribution of secondary formation to atmospheric sulfate may be overestimated in current source apportionment studies.

Summary: The chemical composition of PM2.5 has a significant impact on human health and air quality. Assessing and quantifying the impacts of various factors on PM2.5 chemical components can guide effective regulations to improve air quality. Generalized additive models (GAMs) were used to assess the factors affecting different PM2.5 species in the South Coast Air Basin. Results show that precursor emissions have the most significant effect on PM2.5 species production, while meteorological factors also influence PM2.5 composition. In the future, meteorological factors will become more significant in affecting PM2.5 speciation.

Summary: This study quantifies the temporal changes of precipitation acidity and its dominant acidifying agents over the last two decades by synthesizing bulk precipitation chemistry in forest sites from three monitoring networks. Results show distinct declines of sulfate and nitrate depositions and increases of precipitation pH in northeast America and central and east Europe, but not in Asia during 1999 and 2018. The decreases of sulfate and nitrate depositions likely reflect the long-term effort of pollutant emission controls.

Summary: Soybean plays a critical role in global food security and sustainability, but the interaction between soil nitrogen supply and nitrogen fixation throughout the growing season is poorly understood. This study evaluated the relationship between nitrogen uptake and dry matter, described seasonal changes in soil-plant nitrogen dynamics among genotypes with different genetic backgrounds, and assessed the influence of soil NO3 and NH4 on temporal nitrogen fixation changes. The findings showed that nitrogen uptake from the soil had a greater impact on total nitrogen status than fixation. NH4 exposure and delayed NO3 availability suppressed end-season nitrogen fixation, highlighting the importance of soil nitrogen sources in soybean growth.

Summary: Deposition of atmospheric nitrogen increases soil nitrous oxide emissions, and the commonly used understory nitrogen application methods underestimate the actual impacts due to overlooking nitrogen interception by forest canopies. Our study compared different nitrogen deposition simulation approaches and forms of nitrogen in a Moso bamboo forest, and found that the cumulative nitrous oxide emissions were higher in understory nitrogen application treatments compared to canopy treatments, with greater emissions under inorganic nitrogen application. Considering canopy processes is important for future studies on nitrogen deposition and soil nitrous oxide emissions.

Summary: Global variation in litter decomposition rates is influenced by climate, decomposer taxa, and litter quality. This study explores how litter decomposition rate and quality vary within a species across different latitudes, finding that higher latitude plants have faster decomposition rates due to lower defensive compounds and higher nutrient levels. Additionally, exotic species decomposed faster than native species, indicating differences in defensive mechanisms and nutrient concentrations.

Summary: The study found that abiotic conditions at creek heads are more favorable for Sesarma crabs, leading to the directional movement of consumer fronts towards the creek heads. Crabs exhibit higher densities, richer dissolved oxygen, and lower hydrogen sulfide at creek heads. The rate of erosion at creek heads limits the propagation speed of consumer fronts, rather than the mobility of crabs.

Summary: The abundance of most taxa of the litter fauna primarily depends on habitat, while litter type becomes a stronger driver for some taxa over time. Decomposition rates also strongly depend on habitat, with up to approximately 80% of the initial detrital mass lost over 25 months in marsh and forest habitats. Litter types become more similar with time, and habitat becomes the dominating factor in determining decomposition of older litter.

Summary: As global change alters ecosystems, the importance of subsidies from one habitat to another may change. This study manipulated black mangrove cover and found that increasing mangrove cover decreases the relative importance of marine subsidies into the intertidal at the plot level, but concentrates subsidies at the front edge of the mangrove stand. Storms may temporarily override mangrove attenuation of subsidies. The study emphasizes the importance of understanding the impact of changes in plant species composition on marine subsidies and exchanges among ecosystems.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.
