The participation rate was 100% in all five communities, with 53% of participants were women. Statiscial analysis shows that algal bloom negatively correlate with less fish productivity and positively with unhealthy reservoir indicators. In contrast, clean water positively correlates with healthy reservoir indicators, while algal blooms consistently show negative correlations with all indicators of healthy reservoir. These findings show current reservoir health, with 41% of participants recognizing reservoirs as healthy, 23% as unhealthy and 36% responded as moderate. Laboratory analysis identified 30 phytoplankton genera, with Cyanophyta as the dominant group. Highest phytoplankton density was observed in May, followed by June and April, providing crucial insights into the seasonal dynamics of reservoir ecosystems. Sentinel-2 imagery further highlighted algal bloom fluctuations, the bloom extent particularly increased during May 2023, supporting water quality measurements and validating algae as a community-identified indicator. This study underlines the value and accuracy of community-driven insights in environmental monitoring. The alignment of participatory mapping, laboratory analyses, and remote sensing demonstrates the efficiency of PGIS in managing freshwater resources. By fostering knowledge exchange, this approach promotes sustainable resource monitoring and conservation. These findings represent a significant contribution to the advancement of reservoir monitoring and underscore the importance of prioritizing community-driven initiatives in environmental research.</p>\u0000 </div>","PeriodicalId":55169,"journal":{"name":"Ecohydrology","volume":"18 2","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707599","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}

Weirs, which are structures built across rivers to regulate stream flow, facilitate human water usage, such as water supply and water level regulation. However, they directly alter the cross-sections of rivers, significantly affecting hydraulic parameters such as flow velocity and water depth. This leads to changes in aquatic habitats, reducing their biodiversity and altering the habitat connectivity of aquatic organisms. This study analysed the changes in habitat connectivity of rivers inhabited by diverse fish populations, considering the presence of weirs, flow regimes and fluvial geomorphological characteristics, to help establish eco-friendly riverine environments that support the coexistence of nature and humans. The analysis revealed that the habitat area, depending on the presence or absence of weirs, varied depending on the flow regime and patch size. In drought flow conditions with smaller patches, the habitat area was larger in the presence of weirs. Conversely, in conditions with flow rates at or above low flow and larger patch sizes, the habitat area was larger without the presence of weirs. Additionally, considering fluvial geomorphological characteristics, sections with medium or low sinuosity and bed slope exhibited a larger preferred habitat area in the absence of weirs. The findings of this study contribute to improving aquatic ecosystem connectivity through the evaluation of habitat connectivity changes based on the presence of weirs and flow regime variations.</p>","PeriodicalId":55169,"journal":{"name":"Ecohydrology","volume":"18 2","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eco.70030","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143698921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Salinization and flooding kill trees and favour the encroachment of salt-tolerant marsh vegetation. The hydrology of this ecological transition is complex and requires a multidisciplinary approach. Sea level rise (press) and storms (pulses) act on different timescales, affecting the forest vegetation in different ways. Salinization can occur either by vertical infiltration during flooding or from the aquifer driven by tides and sea level rise. Here, we detail the ecohydrological processes acting in the critical zone of retreating coastal forests. An increase in sea level has a three-pronged effect on flooding and salinization: It raises the maximum elevation of storm surges, shifts the freshwater-saltwater interface inland, and elevates the water table, leading to surface flooding from below. Trees can modify their root systems and local soil hydrology to better withstand salinization. Hydrological stress from intermittent storm surges inhibits tree growth, as evidenced by tree ring analysis. Tree rings also reveal a lag between the time when tree growth significantly slows and when the tree ultimately dies. Tree dieback reduces transpiration, retaining more water in the soil and creating conditions more favourable for flooding. Sedimentation from storm waters combined to organic matter decomposition can change the landscape, affecting flooding and runoff.

The objective was to evaluate how lake surface area (SUA) affects phytoplankton assemblages. The lentic systems were categorized into three SUA groups: I (&lt; 50 ha), II (50–500 ha) and III (&gt; 500 ha). The results showed that both species composition and dominant species varied with SUA. Some species preferred larger SUAs and higher SUA optima values. Phytoplankton biovolume increased with SUA, particularly in Group III, which had the highest total phosphorus (TP). Species richness (alpha diversity) followed a unimodal distribution, peaking in Group II, whereas total species richness (gamma diversity) decreased with increasing SUA. The distribution of gamma diversity among different phytoplankton groups varied across the SUA categories, reflecting their distinct responses to SUA. The PHYTO-TR index proved to be a more precise tool for assessing the ecological quality of lentic systems, based on TP and phytoplankton biovolume. Groups I and II had a higher proportion of high-quality lentic systems. Parameters such as temperature (T), electrical conductivity (EC), alkalinity (ALK), Secchi depth (SD) and TP were significant factors influencing phytoplankton distribution, composition, biovolume and both alpha and gamma diversity, as well as the overall ecological quality. Although the effect of SUA, which correlates with T, ALK, EC and SD, on phytoplankton is largely indirect through these parameters, there was also evidence of a direct effect because of the varying responses of different phytoplankton groups to SUA.</p>\u0000 </div>","PeriodicalId":55169,"journal":{"name":"Ecohydrology","volume":"18 2","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690282","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}

Moreover, turbulence intensity is observed to be 5.8% in emerged vegetation cases, whereas submerged vegetation cases exhibit turbulence intensity of around 5.31%. Results also indicate strong secondary current circulations downstream of vegetation patches, with higher turbulence and vortex formation in emerged cases compared to submerged cases. Turbulence intensity and Reynolds shear stresses are primarily dictated by the submergence state of vegetation patches, with negligible dependence on RE size.

As water availability is a primary driver of ecosystem function, an understanding of water usage and movement during the different phases of ecosystem development is required to ensure successful reclamation. This study captured the evolving evapotranspiration (ET) regime during the initial 7 years post-construction of a fen-upland watershed. Both landscapes exhibited significant biophysical evolution, from bare ground to fully vegetated ecosystems. During bare ground conditions, ET was driven by atmospheric and edaphic controls. In the fen, ponded conditions resulted in consistently high rates of surface evaporation throughout the growing season (3.8 mm/day). In contrast to the drier upland, which exhibited limited evaporation rates (1.2 mm/day), punctuated by small increases in response to precipitation events. Once a plant community was well established, edaphic controls decreased, and ET fluxes were largely driven by plant-mediated responses to atmospheric conditions. In the fen, widespread plant coverage and the establishment of a thick litter layer suppressed surface evaporative losses but increased transpiration, ultimately resulting in lower ET rates (2.5 mm/day). In the upland, the growth and development of treed species resulted in a marked increase in ET rates (2.6 mm/day).

The main findings were as follows: (1) a cyclical trend occurred in wave height (WVH), wavelength (WVL) and shoreline flushing distance (FLD), with distinct oscillation periods and energy centres, notably a 47-day primary oscillation for WVH and WVL, and 40 days for FLD. It underscored the dynamic nature of wind wave interactions and their potential to shape the lake's ecological landscape.

(3) The biodiversity indexes (Shannon Diversity Index [SHDI], Modified Simpson Diversity Index [MSIDI]) and the evenness indexes (Shannon Evenness Index [SHEI], Modified Simpson Evenness Index [MSIEI]) reached the highest in the ecological transition zone and the lowest in the grassland, indicating the importance of these areas for species diversity.
