Summary: Deep phosphorus stocks are not primarily influenced by geogenic or pedological characteristics, but rather by secondary processes such as underground phosphorus translocation. The build-up of deep phosphorus stocks appears to be driven by downslope translocation of P in the interflow, as well as increased sorption of P in floodplain subsoils under low flow conditions. While Gleysol groundwater dynamics may not systematically drive the build-up of deep P stocks, intensive groundwater dynamics on certain sites could contribute to deep P enrichment.

Summary: Assessing water quality in the Kebir-Rhumel watershed using benthic macroinvertebrates and physico-chemical analysis revealed spatial heterogeneity, with higher pollution levels in the Rhumel wadi compared to the El Kebir wadi. Elevated levels of NO2-, NO3-, PO4-3, Cl-, and SM were attributed to human and industrial activities. Canonical correspondence analysis showed that environmental parameters influence macroinvertebrate dynamics, with pollution-resistant taxa dominating in organically rich, low-oxygen conditions. The results from biotic indices confirmed degraded water quality in the Rhumel wadi.

Summary: The traditional urban drainage degrades receiving waters. Alternative approaches, such as dispersed stormwater control measures (SCMs), have potential to protect downstream waters. A catchment-scale experiment was conducted over 19 years to assess the effect of SCMs on stream water quality. The results show that SCMs can reduce phosphorus and nitrogen concentrations, as well as summer temperature, in dry weather. However, their effectiveness is influenced by antecedent rain. SCMs have no effect on suspended solids concentrations, but they increase the contribution of groundwater to baseflows. This experiment strengthens the inference that urban stormwater drainage increases contaminant concentrations in streams and demonstrates that such impacts are reversible and likely preventable.

Summary: Freshwater biodiversity has globally declined significantly, with chemical pollutants playing a probable role. However, the specific impact of pesticide use/pollution on riverine invertebrate communities has not been well quantified. This study investigated the association between pesticide use/pollution and riverine invertebrate communities in England over a 55-year period using the biogeographically independent bioindicator SPEARpesticides. The results showed that the Anglian and Thames regions consistently had the lowest SPEARpesticides scores, indicating a presence of fewer pesticide sensitive species. The Anglian region had the highest pesticide use compared to other regions, and the level of pesticide/insecticide use was negatively correlated with the regional SPEARpesticides score. Biochemical Oxygen Demand and ammonia, as measures of general water quality, were also negatively correlated with the SPEARpesticides scores across the regions, but were not the main drivers for the lower scores seen in the Anglian region. The findings suggest that riverine invertebrate communities in England have been most impacted in the Anglian region, and chronic insecticide exposure is likely a significant factor in shaping the status of these communities.

Summary: The research indicates that the impact of land use on water quality is affected by the width of the buffer zone, and the joint explanatory ability of land use composition and configuration is greater than that of each individually. The patch density and landscape shape of cultivated land, shrubland, and built-up land have significant effects on water quality, demonstrating the importance of a multi-scale perspective in water quality management.

Summary: Although the importance of macroinvertebrates in healthy stream ecosystems is well-understood, studies on sustainable management practices for macroinvertebrate communities in small streams affected by forest harvesting have been limited. This study examined the effects of contemporary forest harvest practices on benthic macroinvertebrate density and community composition in 12 small headwater streams. The results showed that retaining riparian vegetation during clearcut harvesting minimized changes in macroinvertebrate densities and community composition in headwater streams.

Summary: The encroachment of agricultural activities into natural areas poses a growing problem for stream ecological condition. Measurements of stream ecological condition using both biotic and abiotic parameters are crucial, and physical-chemical measures of water quality have been widely used. Recent research has utilized physical habitat structure and catchment land use to better understand water body conditions. However, remote sensing of catchment land use and land cover alone may not be sufficient to predict stream water quality or habitat structure accurately.

Summary: Riparian corridors are crucial for maintaining downstream ecosystem services, such as water quantity and quality. This study proposes a comprehensive decision support framework for managing riparian zones in the Minnesota River Basin. The framework integrates fuzzy analytical hierarchy process and fuzzy inference system to suggest suitable best management practices based on stream features, riparian characteristics, and riparian functions. The results highlight the importance of riparian revegetation, buffer strips, wetland management, the addition of woody debris, and an increase in tree cover as effective BMPs.

Summary: The study explored the claim that river water quality in Great Britain is better now than at any time since the Industrial Revolution. Data and evidence were reviewed for seven categories of water pollutants. The findings suggest that water quality in many rivers downstream of urban centers has improved in sanitary terms, but emerging contaminants and intensive agriculture remain significant challenges. Better identification and prioritization of multiple stressors are needed to enable continued recovery.

Summary: This study explores the influence of North Atlantic Oscillation (NAO) on the synchrony and stability of stream invertebrates in central Wales. The results show that warmer and wetter conditions during positive NAO winters synchronize population and community variations in streams, reducing stability across ecological levels. The findings suggest that large-scale climatic fluctuations can affect inland freshwater ecosystems and highlight the importance of protecting and restoring functional diversity in stream communities to mitigate the impacts of climate change.
