Anthropogenic interventions are threatening small freshwater ecosystems and biodiversity, which continues to decline at an alarming rate. To address their biodiversity value, 210 small waterbodies in Czechia were sampled to determine how different habitat characteristics and anthropogenic-induced disturbances affect selected species community composition. Three types of habitats were chosen: ponds, pools and flooded quarries. The selected sites were sampled for fish with trap nets focussing on native crucian carp (Carassius carassius), sunbleak (Leucaspius delineatus) and invasive gibel carp (Carassius gibelio) and topmouth gudgeon (Pseudorasbora parva). The surface area of the water body, human population within 5 and 10 km radius, water transparency, elevation, macrophyte cover and the other existing fish species, newts and diving beetles were recorded. The two focal native fish species tended to co-occur with alpine newt (Ichthyosaura alpestris), great crested newt (Triturus cristatus), the smooth newt (Lissotriton vulgaris) and diving beetles (Dytiscus sp.), and were associated with sites with higher macrophyte cover. Densely inhabited areas were more likely to contain invasive fish species. Presence of invasive gibel carp and topmouth gudgeon was associated with low habitat quality. Flooded quarries supported fewer common species and had slightly higher diversity among the sampled sites. This study highlights the importance of small artificial water bodies as a secondary habitat for declining fauna associated primarily with floodplain ponds.

This study integrates robust climate change scenarios and hydrological modeling to study the impact of climate change on streamflow, Organic Nitrogen (ORGN), Organic Phosphorus (ORGP), Mineral Phosphorus (MINP), and Nitrate (NO3) concentration in the Bosque watershed in Central Texas, USA. A multi-site and multi-variable calibration/validation and Differential Split Sampling approach was used to calibrate and validate the SWAT model. In future climate scenarios, a steady decline in organic nitrogen, organic phosphorus, and mineral phosphorus was found, primarily associated with decreased precipitation and streamflow. The hotter and drier future climate scenarios would result in a statistically significant increase in nitrate (61–104 %). Changes in water quality parameters were higher in the RCP4.5 emission scenario compared to the RCP2.6 and RCP8.5 emission scenarios. This study highlights the dire effect of climate change on the NO3 concentration, which requires urgent water management interventions to mitigate detrimental repercussions for watershed health.

This study, conducted in the exposed sandy littoral zone with dispersed stands of Potamogeton perfoliatus in the Vistula Lagoon (southern Baltic Sea), aimed to test the following hypotheses:
1.
During the growing season, benthic fauna inhabiting a high-complexity habitat (sandy bottom with below-ground rhizomes and roots, as well as above-ground plant canopies) would exhibit greater taxonomic diversity, density, and biomass than those in the adjacent low-complexity habitat (bare sandy bottom).
2.
During the non-growing period, in areas formerly occupied by plant canopies but with rhizomes and roots still present, macroinvertebrate communities would retain their distinctiveness, resulting in greater taxonomic diversity, density, and biomass compared to neighboring areas of bare sandy bottom (low-complexity habitat).
Contrary to expectations, during the growing season, the habitat with the highest complexity—featuring plant canopies and rhizome/root mats—had lower species richness and diversity compared to the non-vegetated, low-complexity habitat. Additionally, total density and biomass were lower in the more complex habitat. During the non-growing season, both diversity indices were higher in the less complex habitat compared to the more structured habitat, and the differences in total density and biomass were not significant. Consequently, both hypotheses, which suggested higher diversity, density, and biomass in the more structured habitat, were not supported. The study's outcomes may be attributed to the relatively small area of the studied vegetation patches, their shallow depth, and the distinctive characteristics of the lagoon environment, including strong physical forces such as occasional strong wave action and frequent water level fluctuations.

Karst water, as an important source of water supply, is increasingly contaminated with nitrate. Determining the source and transformation of nitrate is key to effectively controlling its diffuse pollution. Defining the sources of nitrate pollution in watersheds plays an important role in the prevention and control of nitrogen pollution in the surface and groundwater and the development and utilization of water bodies. In this study,we conducted sampling in the Gaoping River of Huichuan, Zunyi City, in May (flat-water period), August (abundant-water period), October (flat-water period), and December (dry-water period). We characterized the distribution of nitrate in the surface water and groundwater of the basin using δ15NNO3-, δ18ONO3-, and δ18OH2O isotope tracer techniques and water chemistry analysis methods. The results show that the water chemistry of the study area is mainly influenced by the HCO3Ca type of water and land use. Nitrate contamination in surface water is less affected by human activities and land-use types than groundwater contamination. Surface water pollution is strongly influenced by the amount of rainfall. Based on the SIAR source analysis model,the distribution of NO3- sources was found to be closely related to the land use types. The main sources of nitrate pollution in the water bodies of the Gaoping River Basin can be classified into five categories: chemical fertilizers, atmospheric sedimentation, soil organic nitrogen, livestock, poultry manure, and wastewater. This study provides an important scientific basis for the protection of karst water and the corresponding theoretical support for the control of nitrate pollution in karst areas.

Nature based solutions (NBS) have been successfully applied in developed nations. Its application in developing countries is however still incipient to some extent. Moreover, very few studies have addressed its implementation in the domain of large river systems, which have been exposed to ever increasing anthropogenic pressure in the last decades. The Magdalena River is the main waterway in Colombia, and it exhibits one of the largest sediment loads in South America. This contribution presents the successful operationalization (i.e., hydrological and hydraulic analysis, as well as numerical simulation) of sediment traps for sedimentation control and bank stabilization of the right bank of the Magdalena at Magangué Municipality (lower Magdalena) through wooden sustainable alternatives. The NBS simulation and intervention assessment indicates that the traps effectively restored the bank shore in the critical sector of the study area. To the best of our knowledge, the intervention in question is one of the first of its kind in the region. The numerical results indicate that these traps were able to reduce the exposure of vulnerable communities, not only to floods, but also to negative hydrodynamic changes associated to climate change. Thus, the contribution currently described can potentially provide for practitioners and decision makers a guide for the application of NBS in river engineering, and, for scientists, valuable insights into processes associated with NBS in different environments. We posit that the operationalization of NBS in developing countries needs to be institutionally encouraged through, for example, the construction of a database of successful interventions, and the establishment of methodological guidelines.

This paper addresses an integrated constructed wetland system designed to treat raw wastewater from the process of underground coal gasification. To enhance the performance of the vertical flow constructed wetland technology, UCG-derived char was integrated as an adsorbent. The main objective of the study was to characterize the biofilm structure from UCG-derived adsorbent. This is the preliminary research to characterize the biofilm layer of waste adsorbent used in the wetland column. Findings indicated that the treatment system was able to improve post-processing wastewater chemical composition. During the 45-days experiment wetland with the adsorbent achieved over 90 % efficiency in removing pollutants from treated UCG post-process water. This study demonstrated that UCG-derived adsorbent can be used as a carrier to effectively trap microbes in contaminated environmental systems, facilitating the assessment and study of hydrocarbon-degrading microorganisms. The biofilm on UCG adsorbent was dominated by microbial taxa from Proteobacteria and Firmicutes. Community analysis of UCG char-associated microorganisms revealed taxa related to hydrocarbon-degrading treatments, including Pseudomonas and Bacillus, which may facilitate hydrocarbon degradation and biosurfactant production.

Improvements in the performance of wastewater treatment systems with the so-called nature-based solutions (NBSs) are a challenge regarding the study and development of bench, pilot and real scales units. The huge number of micropollutants, macropollutant load factors, the relationship between microorganisms and macrophytes, possible toxicity changes in the roots of macrophytes in phytoremediation systems, landscape integration and the possibility of making degraded areas recovered through wastewater treatment plants are topics increasingly recurrent. Constructed Wetlands (CWs) are among the NBSs and also considered clean and efficient technologies helping to treat wastewater, with promising results in all issues considered here. Furthermore, studies have reported that microbial association in CWs. mainly fungi. increases the effectiveness of the treatment of different types of wastewaters. Therefore, the objective of this study was to analyze, by bibliometric review, the relationships between the main configurations of CWs used for the treatment of wastewaters and the composition of their fungal community. Data obtained from the bibliometric review were used to gather information about CWs systems, main macrophytes planted on them and associated fungi. As results, a total of 90 articles that address the searched terms (constructed Wetlands AND fungi) were obtained, besides to a variation in fungal composition, covering mainly Arbuscular Mycorrhizal Fungi (AMF). The greatest diversity of fungi was found Subsurface Flow Constructed Wetlands, while the greatest diversity of macrophytes was found in Subsurface Vertical Flow Constructed Wetlands systems. Pragmatis australis was the main macrophyte used in the Superficial Horizontal Flow Constructed Wetlands systems. Finally, the results showed that the fungal community present in CWs plays an important role in the removal of pollutants by different mechanism such as hydrolysis, volatilization, sorption, biodegradation and photolysis. Furthermore, AMF help reduce the stress caused by micropollutants suffered by macrophytes, improve tolerance to the environment, nutrient absorption and assist in denitrification processes.

Inserted in a region known as the Amazon Macrotidal Mangrove Coast (AMMC), the São Marcos Estuarine Complex (SMEC) has presented a scenario of continuous contamination caused mainly by the discharge of domestic, agricultural, and port sewage. Therefore, this study aims to be the first to determine the trophic state of SMEC, assess the ecological status of the phytoplankton community, and apply additive models to investigate the main environmental parameters that drive phytoplankton. Collections were carried out during the dry season (September and December/2018) and the rainy season (March and June/2019). Seasonal influence on environmental and biological factors was observed, especially those used to classify water quality. Based on the Multimetric Trophic Index (TRIX), SMEC was classified as eutrophic, and the general nutritional status of phytoplankton revealed that the system was predominantly nitrogen-limited. The phytoplankton community was dominated by diatoms, with emphasis on the presence of potentially harmful species such as Pseudo-nitzschia pungens, Coscinodiscus centralis, Thalassiosira subtilis and Skeletonema costatum, which can cause ecological and economic losses in the environment. Such species contributed to the low diversity and moderate richness. Hydrological variables such as temperature, salinity, and turbidity, in addition to nutrients, especially nitrate and phosphate, were the main parameters controlling phytoplankton structure and abundance, revealing an indicator community well adapted to local conditions. Overall, the integrated study of trophic and ecological indices in the SMEC appeared to be sensitive to changes in water quality, being an efficient tool to indicate the current scenario of this environment.

The phytoplankton community was dominated by diatoms, with emphasis on the presence of potentially harmful species such as <em>Pseudo-nitzschia pungens, Coscinodiscus centralis, Thalassiosira subtilis</em> and <em>Skeletonema costatum</em>, which can cause ecological and economic losses in the environment. Such species contributed to the low diversity and moderate richness. Hydrological variables such as temperature, salinity, and turbidity, in addition to nutrients, especially nitrate and phosphate, were the main parameters controlling phytoplankton structure and abundance, revealing an indicator community well adapted to local conditions. Overall, the integrated study of trophic and ecological indices in the SMEC appeared to be sensitive to changes in water quality, being an efficient tool to indicate the current scenario of this environment.</div></div>","PeriodicalId":56070,"journal":{"name":"Ecohydrology & Hydrobiology","volume":"25 3","pages":"Pages 618-631"},"PeriodicalIF":2.2,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144895655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eutrophication severely impacts water quality, impeding tourism, recreation, and rendering it unfit for consumption, swimming, and fishing. To address this challenge, innovative methods for nutrient inactivation in lakes and reservoirs are imperative in restoring surface water. In this context, we investigated whether the technology based on ion exchange (IX) resins can decrease the concentrations of nitrate-nitrogen (NO3-N) and phosphate-phosphorus (PO4-P) in the water in the vicinity of the anion exchange resin installation located in the backwater area of a reservoir. The Anion Exchange Resin Installation will be referred to as the Water Quality Improvement Installation (WQII) in this article. We also aimed to identify the factors that affect water quality in the water in the vicinity of the WQII area. Our research area was the Turawa eutrophic reservoir located in south-western Poland (Central Europe). Our results indicate that the WQII effectively lowers the concentrations of NO3-N and PO4-P in the tested water. Environmental factors have negligible influence on NO3-N and PO4-P concentrations in the water in the vicinity of the WQII. An inversely proportional relationship between the removal of NO3-N and PO4-P indicates that the configuration of the regeneration system of each column is appropriate. The WQII effectively decreases NO3-N and PO4-P concentrations during periods of cyanobacterial blooms in the backwater area of the reservoir. This novel WQII utilizing IX technology, emerges as a promising solution for remediating eutrophic water aligning with the Water Framework Directive, assuming the achievement of good water status of water bodies.

There are few reports on the bacterial communities and functions of sediments in Huaihe River. Herein, the structure and functions of sediment bacterial communities in the Anlan Wharf (AL), Bengbu Gate (BZ) and Mohe Estuary (MH) of the Huaihe River Basin were comparatively analyzed using 16S rRNA high-throughput sequencing. The richness and diversity of bacterial communities significantly differed among different watersheds of Huaihe River. Alpha diversity analysis showed that the magnitude of diversity index and richness index of each sampling site ranked in the order of AL > BZ > MH. The bacterial communities in the Huaihe River Basin are dominated by Pseudomonadota, Chloroflexota, Nitrospirota and Bacteroidota at the phylum level, and by Gammaproteobacteria and Deltaproteobacteria at the class level. The sediment bacterial communities were analyzed on the bacterial community function prediction software PICRUSt. The sediment bacterial functions mainly involve 46 gene functional families, such as vitamin and cofactor metabolism, amino acid metabolism, and biosynthesis of secondary metabolism products. The predicted gene copy numbers of the gene function families rank as AL > MH > BZ. This study reveals the structure and function of sediment bacterial communities in different areas of the Huaihe River Basin, and provides scientific basis for subsequent ecological restoration in this basin.
