Summary: This study aimed to examine the assembly mechanisms of microbial communities and the sub-communities with different rarity along the Nu River. The results showed that the assembly of microbial sub-communities was mainly driven by drift and homogenizing dispersal with an increase in rarity. The contribution of stochastic and deterministic processes to the microbial community assembly was correlated with geographic distance and environmental factors, respectively.

Summary: This study characterized riparian tree communities along the Acome riverbank in Guatemala by identifying four main riparian communities and 115 tree species. The study emphasized the crucial role of these riparian tree communities in maintaining water quality, providing habitats for wildlife, and facilitating the movement and dispersal of species. This information is vital for the development of restoration strategies and management plans in the region.

Summary: The WUI is an area where human developments and flammable vegetation merge, leading to increasing losses. This paper studies wildfire spread within WUI communities and proposes an improved model for fire spread.

Summary: This study investigated the role of dissimilatory nitrate reduction to ammonium (DNRA) in the stability of urban river networks and marine ecosystems. The research identified a significant positive correlation between DNRA rate and sediment organic carbon, with Anaeromyxobacter as the dominant genus and both heterotrophic and autotrophic DNRA species present. It added diversity to urban freshwater river ecosystem studies and provided new insights into the biological nitrogen cycle of typical urban inland rivers in eastern China.

Summary: Many terrestrial ecosystems have been significantly transformed by human activities, particularly riverine ecosystems. Through a case study of legacy dike fields along the regulated Rhone River, it was found that long-term channelization and flow regulation have impacted environmental conditions and riparian forests, highlighting the importance of restoration strategies focusing on reconnection between dike fields and rivers.

Summary: This study found that water temperature, rather than the presence of dams, is the main factor influencing the geographical distribution of bacterial communities in cascade reservoirs. There are significant spatial differences in sediment bacterial communities within a reservoir, potentially forming hotspots for biogeochemical cycling. Unlike in deep lakes and deep single reservoirs, the bacterioplankton community composition in deep cascade reservoirs does not have distinctly layered features due to density-induced underwater currents and convection.

Summary: This study examines the contribution of multiple water sources to riparian wetlands in the lower Yellow River using hydrochemistry and isotopic methods. The results show that the Yellow River is the main water source for riparian wetlands, but its contribution varies spatially and temporally. Climate and hydrological variables, particularly suspended sediment content, have a significant impact on water recharge.

Summary: The study shows that the fire danger in the WUI areas of the United States has significantly increased, particularly in the Southwest, Intermountain, and Pacific Southwest regions; rapid population growth in high-danger WUI areas has further exacerbated the risk of fire exposure.

Summary: Afforestation has a strong influence on soil microbial traits, especially microbial biomass and enzyme activity, but the magnitude and direction of these traits following afforestation are unclear. This study found that 15 years of afforestation significantly decreased the contents of total carbon, total nitrogen, available phosphorus, and nitrate in the soil. Microbial biomass and enzymatic activities were also lower in the afforested soils compared to adjacent cropland soils. Afforestation with Morus alba or Salix bablyonica species may reduce soil functions such as carbon storage and nitrogen fertility, suggesting that large-scale afforestation using these species should not be prioritized for restoring soil functions within a short period.

Summary: This study documents the spatial and temporal patterns of effluent uptake by riparian trees using a new application called dendrochemistry. The results confirm the presence of anthropogenic Gd in riparian trees and demonstrate that Gd concentrations in tree rings can be a useful monitoring tool for evaluating changes in surface water quality.

Summary: The study investigates the impact of land use on surface water quality, finding that nitrogen is the dominant nutrient and has significant correlations with other water quality parameters when influenced by grassland and farmland. Land use in buffers can directly and effectively affect water quality.

Summary: This paper discusses a stochastic methodology to evaluate the community's response to potential wildfire scenarios. The methodology breaks the wildfire incident into two segments and integrates the two spread models using a conditional probability. Two case studies in California demonstrate variations in fire spread within communities.

Summary: The use of sodium chloride for winter deicing has led to increasing chloride concentrations in urban watersheds, which pose threats to drinking water resources, aquatic life, and vegetation. Human modifications of the environment in urban areas, such as increased impervious surface cover and disconnection of stream corridors from riparian groundwater, impact chloride fate and transport. Monitoring continuous chloride load estimates along a stream channel can help identify sources and sinks of chloride in urban environments.

Summary: This study assessed the effectiveness of different insect sampling methods in riparian areas and found variations between different plant communities and insect orders. The similarities between terrestrial insect communities were relatively high, even across different years. The optimal sampling size for obtaining approximately 80% of total species was estimated for each survey site.
