Summary: The different characteristics of impervious urban surfaces and natural underlying surfaces affect water and heat balances, with consequent impacts on evapotranspiration (ET). In this study, a new model incorporating the van Dijk model's interception evaporation algorithm and an impervious surface evaporation module was developed to simulate urban ecosystems. The model performance was validated and the net increase in evaporation due to increased impervious surface changes was estimated. The results highlight the importance of considering the synergistic modulation of impervious surface changes and vegetation changes on evapotranspiration.

Summary: Soil biota have variable effects on plant species, and these effects can be modified by the chemistry of plant leaves. In this study, we examined the effects of soil biota associated with an invasive tree species and native plants on conspecifics and other species. We found that the soil biota associated with the invasive tree species had positive effects on conspecifics and another invader, but negative effects on native species. The addition of leaf leachate from the invasive species increased positive plant-soil feedbacks for both the invasive species and other plants.

Summary: Stream metabolism is influenced by multiple factors, with biomass being a dominant control on metabolism. Comparative analyses of streams should consider both spatial and temporal variations in stream metabolism to accurately assess differences in trophic status, biomass, and nutrient cycling. This study evaluated the effects of environmental factors on stream metabolism during a summer low-flow period at 17 stream sites in the United States and found that biomass, orthophosphate, and canopy cover were important factors influencing gross primary production.

Summary: Human impacts, such as nutrient pollution and land-use change, have led to declines in the quality and quantity of freshwater resources. This study analyzes the effects of human stressors on stream ecosystem functions and finds that most stressors inhibit ecosystem functioning. Nitrate uptake efficiency is particularly affected, with agriculture having the largest inhibitory effect. However, there are both negative and positive effects within each stressor-function pair. Wastewater effluents, agriculture, and urban land use have the strongest overall effects. These findings highlight the importance of understanding the multifunctionality of streams and rivers and the need for ecological function-based freshwater management strategies.

Summary: Human-induced abiotic global environmental changes (GECs) and the spread of non-native invasive species have significant effects on ecosystems. Invasions tend to have more detrimental effects than GECs, and the interactions between invasions and GECs are mostly antagonistic but can also be synergistic, leading to more harmful outcomes in some cases.

Summary: This study found that an intervention using l-theanine (LTA) and epigallocatechin gallate (EGCG) can alleviate ovalbumin allergy (OVA-A) by modulating intestinal-specific immunity. The combination of LTA and EGCG has a better effect than using them separately. Moreover, LTA and EGCG also improve OVA-A by reducing the number of dendritic cells, inhibiting the Th2 immune response, and inhibiting mast cell degranulation.

Summary: The study found that nitrogen-fixing Acacia species can decrease tree species diversity, alter litter quality, and increase water nitrogen concentration in invaded riparian forests. Litter diversity has antagonistic effects on litter decomposition in streams, which can be modulated by water nitrogen concentration. Litter decomposition rates and microbial decomposer activity are higher in invaded streams, likely due to higher water nitrogen concentration, although the effects are small.

Summary: Microbes play a critical role in plant litter decomposition and the fate of carbon in rivers and riparian zones. The process of nutrient immobilization, whereby microbes acquire nitrogen and phosphorus from the environment during the decomposition of low-nutrient plant litter, is influenced by nutrient loading and changing climate. However, environmental controls on immobilization are poorly understood due to the complex interplay between environmental factors and plant litter chemistry.

Summary: A study found that temperature plays an important role in microbial-mediated leaf degradation in streams experiencing intermittency. During short dry periods, aquatic fungal communities invest in energetically-expensive physiological responses to desiccation, while longer drought periods result in lower fungal diversity and negative effects on fungal growth and reproductive capacity. Native riparian vegetation plays a critical role in protecting freshwater ecosystems from intensified drought periods in intermittently flowing streams.

Summary: Freshwater salinization is a growing threat that affects aquatic systems worldwide. Human activities contribute to the contamination of streams and rivers, resulting in chronic or pulsed salt additions. This study compared the effects of continuous and pulsed salt addition on microbial-mediated litter decomposition and associated microbial endpoints. The results showed that chronic salt exposure had a greater impact on microbial activity, reproductive outputs, and fungal richness than pulsed inputs, despite no effect on fungal biomass. The findings suggest that the effective salt concentration to alter fungal activity may be higher in pulsed salinization.

Summary: Streams in active volcanic islands are often naturally enriched with metals. In the Azores archipelago, some streams have high concentrations of metals. In this study, leaf litter with different characteristics was exposed in metal-enriched and reference streams to assess the feeding preferences and performance of a caddisfly species. The results suggest that the caddisfly's performance was more influenced by litter characteristics than by metal enrichment.

Summary: Droughts have significant impacts on stream ecosystem functioning, particularly on the decomposition of litter. A meta-analysis of 50 studies showed that overall, drought reduced litter decomposition by 43%, affecting energy and matter fluxes in food webs. The magnitude of drought effects depended on factors such as drought type, decomposer community, climate, and litter identity, with stronger effects in severe drought conditions and certain stream characteristics.
