To prevent eels from entering turbines, effective guidance systems are needed to redirect downstream-migrating eels towards safer alternative passage routes. Although physical guidance screens may have very high guidance efficiencies, these generally come with high construction and maintenance costs and are difficult to scale up to large rivers. Behavioural guidance systems are typically less costly, but have often been ineffective. Hence, more work is needed to identify more effective behavioural solutions or physical barriers that are less costly to upscale. In this study, we assessed the performance of a physical net barrier (23 mm mesh size) and a behavioural bubble curtain guidance solution, for downstream-migrating eels and compared these with a guidance-free control at four different water velocities (0.1, 0.4, 0.7 and 1 m/s) in a large experimental flume using PIT-telemetry and video. The overall passage rate with the net barrier was 68 % higher than during the control treatment, whereas there was no significant difference between the bubble curtain and the control. We also found an effect of eel body size, where larger eels were less likely to enter the bypass than smaller eels. Velocity did not influence passage rate. Video data, in addition, revealed that b guidance along the barrier was greater, and passes through the barrier fewer, for the net barrier than for the bubble curtain and the control. The results suggest that net guidance solution for downstream guidance of eels should be explored further, whereas the bubble curtain does not appear appropriate for eel guidance.</div></div>","PeriodicalId":11490,"journal":{"name":"Ecological Engineering","volume":"215 ","pages":"Article 107599"},"PeriodicalIF":3.9,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143644251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The role of vegetation cover was also evaluated, showing that sedimentation rates were significantly higher within 1 m downstream of trees compared to distances of 3 m and 7 m at upstream of trees. The results revealing that as the distance from the tree increases, sedimentation decreases in both upstream and downstream directions. Despite the overarching influence of erosion, sedimentation emerged as a dominant process downstream.

To investigate the long-term impacts of mining and ecological restoration on vegetation communities and their below-ground habitat structure in mining areas, this study aims to reveal the relationship between aboveground and underground vegetation structures and explore the spatial heterogeneity of vegetation root systems and soil properties across different soil layers. This study uses the natural background area as a reference ecosystem and selects the mining disturbance area, mining restoration area, and natural background area in the southern Taihang Mountains as the research sites. Field surveys and laboratory analyses of plant communities and their below-ground habitats were conducted using ecological geology theories and methods. This mainly included plant species, height, and cover, as well as the distribution of fine roots and soil physicochemical properties within soil profiles (0–100 cm). Firstly, mining activities impose long-term adverse impacts on vegetation diversity and growth, resulting in a “patchy” distribution of vegetation and soil that disrupts the synergistic interactions between vegetation and soil systems. However, mine restoration gradually re-establishes the coordination between vegetation and soil systems. Secondly, there is a strong correlation between the aboveground and underground structures of vegetation. Both the aboveground and underground components of vegetation exhibit a layered structure. The distribution range of root systems varies across different plant species. Significant differences in the frequency of fine roots are observed in the soil surface layer (0–20 cm) between different ecosystems, with overlap occurring in the 20–40 cm layer, and minimal differences found in the 40–100 cm layer. Finally, the contents of soil available N, available P, and organic matter exhibit a decreasing trend with increasing soil depth, with distribution curves resembling an “S” shape. Nutrient levels are higher in the surface soil, where fine plant roots are concentrated. A layered pattern exists in the spatial heterogeneity of plant root systems and soil available N, available K, available P, and organic matter. It is suggested that the relationship between plant diversity and soil spatial heterogeneity should consider the below-ground habitat range associated with the survival of tree, shrub, and grass vegetation. This study is of significant importance for scientifically guiding the ecological environment protection and restoration of mining areas.</div></div>","PeriodicalId":11490,"journal":{"name":"Ecological Engineering","volume":"215 ","pages":"Article 107601"},"PeriodicalIF":3.9,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143619711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

We have evaluated the recovery process 23 years after the change in technology by analysing the current contamination of the ecosystem around the factory. In 2019, we sampled the soil, herbaceous plants (<em>Arrhenatherum elatius</em> and <em>Artemisia vulgaris</em>), and woody plants (<em>Salix euxina</em>, <em>Alnus glutinosa</em>, and <em>Carpinus betulus</em>) along three transects running in different directions from the smelter and compared our results with those of a study conducted in 1971.

Some elements accumulated more in trees (light elements, Sr, Ca, Zn, and Mn) whereas others accumulated more in herbs (K, P, Cl, Si, and Cu). A resurvey of vegetation data has shown clear signs of ecosystem recovery. Over the past ∼50 years, soil fluoride contamination has decreased several-fold and the slope of the distance–decay relationship has flattened. As regards plant leaf biomass, the distance–decay relation has faded out or even reversed, but the concentrations of fluorine in leaves further from the source of pollution remain as high as, or even exceed, values measured ∼50 years ago. Although the ecosystem around the plant is recovering from the past pollution, the revitalization process is still ongoing. Most importantly, concentrations of fluorine in plant biomass continue to exceed the health risk limit, and the meadows adjacent to the smelter are still unsuitable for agricultural purposes.

There was a positive mutual promotion relationship between EBF and WR in the watershed, the guarantee or increase of EBF can provide sufficient water resources for the growth of plants and animals in wetlands, and maintain the stability of wetland ecological environment to promote WR. The WR can increase river runoff by promoting water circulation and other means, ensuring that EBF is continuously met, thereby improving the health and stability of river ecosystems.
