The Hanjiang River Basin is the source of the middle route of the south-to-north water diversion project; understanding the characteristics of tree transpiration in the basin and its key controlling factors is of great importance for sustainable water resources management of the region. In this study, we measured the sap flux density as a surrogate of transpiration for three representative tree species (oak, poplar and pine) from January 2021 to December 2023 in the Hanjiang River Basin. Results showed that incoming short-wave radiation (Rsi) and vapour pressure deficit (VPD) are the major factors controlling daytime sap flux density. The nighttime sap flux density generally correlates with the daytime sap flux density for all the tree species. A statistical model was developed for estimating daytime sap flux density based on Rsi and VPD, and the nighttime sap flux density is estimated using its dependence on daytime sap flux density. The proposed model could explain more than 85% of sap flux density variation of the three tree species. Soil water content (SWC) exhibited different impacts on sap flux density among the three tree species, with oak and pine showing clear SWC control, while poplar showed negligible SWC control. Incorporating SWC in the proposed statistical model improved the model performance for oak and pine during dry periods. This study revealed the characteristics of sap flux density of oak, pine and poplar in the Hanjiang River Basin and proposed a statistical sap flux density model for sap flux density simulations in the humid region of China.</p>\u0000 </div>","PeriodicalId":55169,"journal":{"name":"Ecohydrology","volume":"18 5","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144861713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

However, restoration designs focusing only on increasing the quantity of spawning habitats for fish can result in little to no improvement, as the presence of various potential barriers would severely impede fish from accessing upstream habitats and utilizing their resources, thus further affecting the effectiveness of restoration efforts. Here, we suggest a more comprehensive assessment framework which closely links potential barriers and upstream migration opportunities with the quantity and quality of fish spawning habitats. This framework was implemented to assess the influence of potential migration barriers on the availability of spawning habitats in order to enhance the pertinence and effectiveness of river restoration technologies. In this study, we used the Heishui River, a primary tributary of the Jinsha River, as a case study to research the distribution of fish potential migration obstacles under hydropower development, and restoration efforts were designed to coordinate the accessibility and quality of spawning habitat, which was beneficial for increasing the restoration success probability. The results showed that neglecting river potential barriers would lead to overestimation of fish spawning habitat effectiveness. The effective spawning habitat (ESH) determined by considering potential barriers was reduced by 54.0%–86.9% (for <i>Schizothorax wangchiachii</i>) and 31.4%–86.9% (for <i>Jinshaia sinensis</i>) compared with the traditional weighted usable area (WUA) thus may lead to the deviation of ecological restoration patterns and effects. We highlight that, in the river ecological restoration targeting migratory species, priority should be given to potential barriers restoration close to the downstream estuary and those areas with poorer habitat quality, so as to ensure the effectiveness of more and better-quality spawning habitats. The proposed framework can help managers in conducting sustainable assessments and conservation of potential habitats while informing decisions on habitat restoration priorities.</p>\u0000 </div>","PeriodicalId":55169,"journal":{"name":"Ecohydrology","volume":"18 5","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144832997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

A thorough understanding of these drivers is essential for maintaining fish recruitment in flow-regulated rivers. In the Murray–Darling Basin (MDB) in Australia, golden perch (<i>Macquaria ambigua</i>) are an iconic species with a life history characterised by irregular, strong recruitment of year classes. In-channel flow pulses and overbank flows are important for spawning and recruitment; however, the drivers of fluctuations in golden perch recruitment have not been sufficiently quantified to allow for full operationalisation into river and fishery management. We used long-term standardised electrofishing data to model relationships between the relative abundance of young-of-the-year (YOY) golden perch with large-scale climate indices, local river hydrology and temperature, and river/fishery management actions. While consistent recruitment was observed in only five rivers, there were strong, positive associations between the abundance of YOY golden perch and two broadscale climatic drivers (Australian Monsoonal Index and total rainfall across the northern MDB). The driver of these relationships is likely to be the effects of climate on local river discharge and temperature. YOY abundance increased with temperature and generally increased with river discharge to an optimum before declining at a very high discharge. We also found positive but variable effects of stocking, suggesting that stocking of fish can augment natural populations but that outcomes are spatially and temporally inconsistent.

Analysing the multi-scale mechanism and ecological effects of precipitation on wetland vegetation diversity patterns is crucial for wetland ecological restoration and biodiversity conservation. Based on the analysis of spatiotemporal heterogeneity and variation of the precipitation process, this paper constructed a high spatiotemporal resolution vegetation dynamic dataset of Poyang Lake by integrating multi-source remote sensing data and a machine learning method, and reveals the multi-scale influences and time lag effects of the precipitation process on the vegetation diversity pattern. The results showed as follows: (1) The spatial distribution of precipitation in Poyang Lake was unbalanced, and exhibited an overall increasing trend, with the precipitation intensity index showing non-stationary characteristics relatively. (2) From 2000 to 2020, vegetation diversity exhibited significant spatiotemporal heterogeneity. Increased vegetation landscape dominance was associated with a decrease in diversity and evenness indices, shifting the landscape distribution from balanced to unbalanced. (3) Vegetation diversity exhibited a notable lag in its response to precipitation, with the timing and magnitude of the response varying depending on the precipitation distribution and timescale. At the monthly scale, precipitation exhibited a negative correlation with Shannon diversity index (SHDI), Shannon evenness index (SHEI) and richness index (PT), but a positive correlation with Shannon dominance index (DI). The response intensity of the vegetation diversity pattern to precipitation followed the order: precipitation of month (PM), maximum 5-day precipitation amount (RX5day), and maximum 1-day precipitation amount (RX1day). The response of the vegetation diversity pattern to PM displayed both time-lag and cumulative effects. At the annual scale, annual total wet days precipitation (PRCPTOT) and precipitation frequency indices (R20, R25) significantly influenced the vegetation diversity pattern within the same year. The precipitation intensity index exerted a significant influence on the vegetation diversity pattern primarily with a 3–4 year lag. The influence of the precipitation process on the vegetation diversity pattern has a strong relationship with its instability characteristics. Our findings can offer valuable insights for the conservation and restoration of wetland vegetation diversity, and provide a scientific foundation for the sustainable management of the lake ecosystem.</p>\u0000 </div>","PeriodicalId":55169,"journal":{"name":"Ecohydrology","volume":"18 5","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144815224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Meanwhile, redundancy analysis (RDA) and generalized additive models (GAM) were used to evaluate the response of fish community diversity to water level fluctuations. We collected 63 fish species belonging to 7 orders, 13 families and 39 genera, with Cypriniformes being the dominant order. According to RDA, habitat changes driven by water level fluctuations were the primary factors underlying the shifts in fish community diversity. The GAM model further revealed that water level changes directly impacted the diversity of the fish community, leading to a decrease in the taxonomic distinctness index but an increase in species diversity, taxonomic diversity and functional diversity. Particularly, the number of species, the variation in the taxonomic distinctness index and the functional richness index exhibited highly significant correlations with water levels (<i>p</i> &lt; 0.001). Therefore, high water levels were the primary and crucial factor in maintaining the fish community diversity in the waterway connecting Poyang Lake and the Yangtze River.

Protecting favourite fish niches and identifying their drivers for spatial-temporal change can effectively regulate the intensity of human activities and adapt to climate change. However, previous research on the driving factors for spatial and temporal niche change is rarely reported, severely limiting the efficiency of regulation and adaptation. Therefore, this paper presents a new framework to explore possible factors driving the change of fish niche. Based on 12 large-scale field in situ sampling data from 2014 to 2018 and 2023, a dominance model was firstly used to screen dominant fish. Secondly, niche models of width and overlap were used to calculate fish niches, and MK mutation point test was used to determine mutations of fish and habitat relationship. Then, the correlation between habitat factors and fish density in biomass was determined with the help of CCA. Finally, a partial correlation analysis model was used to identify key driving factors. Results showed that there are nine dominant species, and in the areas with high water temperature in middle and low latitudes, <i>Cyprinus carpio</i> might become the fish species with the largest niche breadth. The key factors driving niche change of the dominant fish in the lower Yellow River are nitrate, total nitrogen and chlorine. What is worth noticing is that water temperature and dissolved oxygen may be key drivers for fish that survive in cold environments. Annually, the factors having the greatest to least influence on the niche of dominant fish were hydrological, water quality physical and water quality chemical factors. For hydrological factors, the dominant fish have the largest niche breadth in summer and the largest niche overlap in spring. For water quality physical factors, dominant fish have the largest niche breadth and the largest niche overlap in summer. For water quality chemical factors, the dominant fish have the largest niche breadth in summer, and niche overlap remains stable between seasons. Upstream and downstream fish niches differ significantly in mountain rivers with weirs. Hydrological factors have the greatest impact on niches of dominant fish in rivers with poor river network connectivity. Water quality indicators have the greatest impact on niches in heavily polluted watersheds. This study can provide a scientific basis for the conservation of fish diversity and ecological restoration in the Yellow River Basin. It can also provide reference and guidance for similar river basins around the world to cope with climate change, regulate human activities and enhance biodiversity.</p>\u0000 </div>","PeriodicalId":55169,"journal":{"name":"Ecohydrology","volume":"18 5","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144767556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}
