Summary: The study investigated the forms and concentrations of nitrogen (N) in rainfall, throughfall, and stormwater runoff in a subtropical urban ecosystem, as well as evaluated the optical properties and expected lability of dissolved organic matter (DOM) in the samples using fluorescence spectroscopy. The results showed that both inorganic and organic N were present in rainfall, with organic N accounting for nearly 50% of total dissolved N. The urban water cycle enriched total dissolved N, primarily from dissolved organic N. The study also found that throughfall had higher humification index and lower biological index compared to rainfall, indicating the presence of higher molecular weight compounds with greater recalcitrance. This study highlights the importance of dissolved organic N in urban rainfall, stormwater, and throughfall and reveals the changes in chemical composition of dissolved organic nutrients during the transformation from rainfall to throughfall in the urban tree canopy.

Summary: The study found that concentrations of DOC and TDN in trees decreased exponentially with increasing precipitation, while stream concentrations increased with streamflow. In most cases, the fluxes of DOC and TDN from trees via throughfall and stemflow greatly exceeded stream fluxes, but the imbalance narrowed for larger storm events. The research highlights the differing impacts of event size on tree versus stream fluxes, which have important implications for forested ecosystems as hydrological events increase in intensity and frequency due to climate change.

Summary: A comprehensive assessment of nitrogen species in stream water reveals shifts in dissolved nitrogen pool composition from highly heterogeneous to primarily inorganic nitrogen under nutrient enrichment from human disturbances. With increasing total dissolved nitrogen concentrations, inorganic nitrogen dominates the pool while dissolved organic nitrogen decreases. These changes in stoichiometry may have significant implications for global biogeochemical cycles of carbon and nitrogen in freshwater ecosystems.

Summary: In this study, the variation of dissolved organic nitrogen (DON) load in different seasons in the Fengyu River watershed in Southwest China from 2011 to 2016 was comprehensively investigated using the LOADEST model and nonparametric change-point analysis. The results showed that the wet season is the peak period for DON loss, with an average cumulative load of 14.1 tons, accounting for 72.5% of the annual load. Baseflow was identified as the main pathway for DON export, accounting for about 74.4% of the stream export load. Furthermore, the threshold streamflow for abrupt changes in DON concentration was found to be 2.03 m3/s to 2.15 m3/s. When the streamflow is below 2.15 m3/s, the concentration of riverine DON increases rapidly, posing a significant threat to human drinking water safety. This study provides a scientific basis for regulating DON at the watershed scale and protecting water quality in drinking water source areas.

Summary: Soil dissolved organic matter (DOM) plays a critical role in regulating the cycling of terrestrial biogeochemistry. N addition significantly increased soil DOM concentration, with a greater impact on dissolved organic nitrogen (DON) than dissolved organic carbon (DOC). The level of N addition was positively correlated with soil DOC and DON concentrations, and the influence of N addition on soil DOC concentration decreased with higher initial soil total nitrogen (TN). Mean annual precipitation (MAP) facilitated the leaching out of soil DON and had a negative impact on its concentration under N addition. Increased soil depth and initial soil pH affected the soil DOC and DON concentrations, with DOC accumulating in the top soil and DON leaching to deeper soil. This study provides a mechanistic understanding of the influence of N addition on terrestrial ecosystem C and N dynamics at the regional scale.

Summary: The study found that storm events mobilized dissolved organic carbon and nitrogen, with proteins playing a key role and exhibiting different dynamics at different stages of the storm. This suggests that there is spatial and temporal separation of molecular groups within the pools of dissolved organic carbon and nitrogen, leading to changing composition of DOC through a storm cycle.

Summary: The experiment on grazing-exclusion and climate warming effects in alpine meadows revealed that grazing-exclusion significantly decreased potential nitrogen mineralization, and climate warming could amplify the adverse effects of grazing-exclusion. Light-intensity grazing was beneficial for increasing soil enzyme activity and nitrogen mineralization in alpine meadows, providing important guidance for sustainable grazing management in the face of climate change.

Summary: This study aimed to develop an empirical stress-level scheme to describe the physiological response of mature European beech trees to drought. The researchers identified five stress levels based on the observed responses to decreasing water potential. They found that exposure to stress levels III-V for only one month was enough to trigger substantial crown dieback in beech trees on shallow soils, while deep soil with high water holding capacity prevented drought stress in beech trees.

Summary: Climate change can have strong and rapid effects on ecosystems, but our understanding of how different traits and functions of individual trees and the overall ecosystem respond to these changes is still limited. By conducting an irrigation experiment in Switzerland over 15 years, we found that increased water availability had varying effects on different traits and functions. The responses of aboveground tree traits were faster and stronger compared to belowground tree traits. Overall, our results highlight the complex and dynamic nature of ecosystem responses to climate change.

Summary: This study on the daily radial growth of 160 individuals of seven temperate tree species in Switzerland over 8 years revealed that growth is influenced by day length, air, and soil moisture. The number of days with growth largely determines annual growth, with growth being constrained by day length. Researchers call for incorporating these non-linear intra-annual and species-specific growth dynamics into tree and forest models to improve predictions under climate change.

Summary: This study investigates the factors controlling stomatal uptake of atmospheric gaseous elemental mercury (Hg(0)) by tree foliage, using foliage samples from across Europe. The study finds that the functional group of trees and the nutrient content of the leaves significantly impact foliar stomatal Hg uptake, while water vapor pressure deficit and soil water content also play a role in regulating Hg uptake. These findings suggest the need to consider tree physiological activity and stomatal response in models of Hg cycling in the future.

Summary: This study investigated the changes in nitrogen dioxide (NO2) air pollution levels and their disparities in California, U.S. during the pandemic of coronavirus disease 2019 (COVID-19). The results showed a decrease in NO2 concentrations, especially in urban and high-traffic areas. However, socially vulnerable populations still experienced higher levels of NO2 exposure. The study suggests that reducing NO2 disparities, particularly racial inequity, can be achieved through continued regulatory actions targeting traffic-related NOx emissions.

Summary: This study investigates the chemical composition and oxidative potential of PM10 particles in the Po Valley, Italy, and demonstrates the impact of high levels of atmosphere ammonia. The rural area had significantly higher ammonia concentrations compared to the urban site, resulting in higher levels of secondary inorganic aerosol. Although the SIA components did not contribute significantly to the PM10 oxidative reactivity, they were correlated with the oxidative potential measurements. This suggests that the contribution of SIA to PM oxidative toxicity cannot be ignored.
