Summary: This study aimed to identify the pattern and diversity of macrophytes in rivers under substantial hydromorphological degradation, taking into account water quality factors. The study was conducted in 190 lowland rivers in Poland that had undergone channel alterations. The results showed that the number of identified taxa was consistent with natural/seminatural rivers, but nearly 25% of the survey sites had low species richness. The macrophyte species were mainly determined by hydromorphological degradation and other environmental factors such as water quality and channel dimensions.

Summary: This study investigated the characterization and response of Potamogeton crispus and epiphytic microbial communities in a micro-polluted urban river. The results showed that P. crispus restoration decreased pollutant concentrations and increased microbial diversity, highlighting the potential of submerged macrophytes in water purification.

Summary: This article presents a methodological approach for the implementation of a macrophyte index in the riverine systems of Greece, which is used to assess the ecological status of the inland waters. The study shows that hydromorphological modifications are the main environmental stressors affecting the ecological quality, while physicochemical stressors are of lesser importance. The research also reveals that the majority of the sites failed to meet the Good ecological quality class according to the Water Framework Directive.

Summary: Network theory provides innovative tools to explore complex ecological mechanisms regulating species associations and interactions. However, the application of network approaches is unevenly distributed across different study systems, with aquatic macrophyte-animal associations in coastal environments being largely neglected. Network analysis has the potential to broaden our understanding of coastal ecosystems and their response to anthropogenic disturbance and environmental change.

Summary: We examined patterns of species composition and macrophyte abundance in the Upper Mississippi River (UMR) and found that water velocity, depth, wind fetch, and water clarity influenced macrophyte abundance and diversity. Three ecologically important macrophyte genera occupied different ecological niches, and there were significant increases in the abundance of V. americana and the cover of Z. aquatica in some reaches of the UMR from 1998-2019.

Summary: In this study, the individual and combined effects of glyphosate and AMPA on the physiology of mosquito larvae were evaluated. The presence of the aquatic macrophyte, Salvinia molesta, was found to mitigate the toxicological impacts of the compounds by removing them from the water.

Summary: The aim of this study was to investigate the changes in macrophyte community along the Izica River over time. The researchers surveyed the distribution and abundance of macrophyte species in 1996, 2000, and 2016, and calculated the River Macrophyte Index (RMI) to assess the ecological status of the river. The results showed significant changes in the species composition of the macrophyte community over the years, which could be attributed to environmental factors and human activities.

Summary: This study focused on the East-Liao River basin and discussed the delimitation method of ecological security evaluation, as well as proposed countermeasures and approaches for watershed ecological security regulation. Results showed significant spatial differences in ecological security levels based on ecological function zones, with a certain spatial aggregation trend observed.

Summary: This study utilized a support vector machine model to predict the reproductive toxicity of EDCs, showing that the model provided more accurate toxicity prediction data compared to the ICE model. The application of predicted toxicity data supplemented observed data for ecological risk assessment of EDCs in the Yangtze River, highlighting the significant ecological risk of certain estrogen compounds.

Summary: The study found that water-column nutrients have a minor influence on macrophyte species richness and no significant influence on macrophyte diversity. It concluded that macrophytes are sensitive to environmental changes but respond to a combination of ecological factors rather than nutrient levels alone.

Summary: Shallow freshwater ecosystems emit large amounts of greenhouse gases, but the emissions are highly variable. The role of aquatic macrophytes in regulating greenhouse gas emissions is uncertain. This study found that high density of submersed macrophytes results in higher concentrations and emissions of carbon dioxide and methane, while lower and medium densities have no significant difference in methane concentration. The high density treatment also showed a loss of biomass, indicating die-off and addition of organic matter to the sediment. High organic matter loading and low dissolved oxygen likely stimulated greenhouse gas production in the high density treatment.

Summary: The density and growth cycle of submersed macrophytes play a crucial role in regulating greenhouse gas emissions in shallow freshwater ecosystems. High density macrophytes increase the concentration and emissions of CO2 and CH4, resulting in increased greenhouse gas production due to high organic matter loading and low dissolved oxygen.

Summary: This study focuses on the occurrence of microplastics (MPs) in the water, sediment, and aquatic species of the Buriganga River in Bangladesh, with an ecological risk assessment perspective. The study found that the river is highly polluted and contains fibrous and fragmented MPs, predominantly in blue. The most commonly identified polymer types are PETE, EVA, HDPE, ABS, CA, and nylon.

Summary: By analyzing a 22-year dataset from the Upper Mississippi River in the USA, we found that five new aquatic vegetation types emerged during the early and late phases of recovery. These types were associated with factors such as inundation depth and duration, system productivity, and water clarity. These vegetation types are of high ecological value to fish and wildlife, making them important targets for restoration and conservation.

Summary: The Karun River in Iran, the longest river in the country, is facing ecological risks due to pollution from industries, wastewaters, and dust storms. A study on sediment quality and heavy metal contamination levels since 1944 revealed that the river is highly contaminated, especially in the north of Ahvaz. The role of certain heavy metals, such as Cu, Ni, Cr, and Zn, in increasing contamination levels since 1960 was emphasized. The study also recommended the use of geochemical indicators to assess heavy metal bioavailability and the implementation of control and mitigation measures to protect the river ecosystem and human health.
