The influence of microtopography (lawns and hummock-hollow complexes) in the biogeochemical dynamics of dissolved organic and inorganic carbon (DOC and DIC) and dissolved CH and CO is generally miss-considered. Southernmost Patagonia has huge areas of pristine peatlands, which are still in a largely natural state with scarce anthropogenic influence. In this study we provide foundational insights into the dynamics of greenhouse gasses (GHGs) and DOC in dominated peatlands of Southern Patagonia, assessing the impact of microtopography on these dynamics. The stocks of dissolved GHGs and DOC in hummock-hollows complex and lawns were analysed at three depths (25, 50, and 75 cm) in four ombrotrophic peatbogs. CH, NO and CO fluxes, net ecosystem exchange (NEE) and gross primary productivity (GPP) were also studied. CO and CH fluxes were strongly affected by microtopography. Hummock-hollows showed higher CO fluxes, and temperature and radiation were the main drivers for respiration and GPP, respectively. In addition, in this microtopography, higher DOC concentrations were observed at the top depth. In contrast, lawns acted as a source of CH, with higher emission rates and high dissolved GHGs concentration throughout the depth profile.","PeriodicalId":56070,"journal":{"name":"Ecohydrology & Hydrobiology","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140167399","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}

It is essential to recognize the complexities of urban growth along with dynamic and static natural parameters that influence the groundwater recharge in the urban region. No substantial inclusion of Groundwater Recharge Potential Zones (GWRPZ) is evident in contemporary master plans of Indian cities, resulting in a declining trend of groundwater tables with increasing dependency. The study discusses temporal changes in the urban LULC of Ajmer City in the State of Rajasthan in India and its impact on the overall Groundwater Recharge Potential Zone over a duration. Nine physical parameters, geology, lithology, geomorphology, lineament density, slope, drainage density, groundwater table, LULC and Rainfall, are used as thematic layers along with their subclasses. The Multi-criteria Decision Analysis of AHP and Weighted Overlay Analysis in GIS are applied to analyze variations at the spatial level on a temporal basis. In addition, Geostatistical techniques such as Empirical Bayesian Kriging (EBK) and Inverse Distance Weightage (IDW) are also applied to interpolate and analyze the thematic layers of the Groundwater table and Rainfall, respectively. The study delineates and analyzes the spatiotemporal variations in the GWRPZs. The confusion matrix method is also applied for validation and accuracy, which is crucial for rationalizing the water-sensitive physical planning process and instrumental in formulating suitable strategies and guidelines for preserving, managing, and retrofitting the groundwater recharge zones at the urban level in the Indian scenario.","PeriodicalId":56070,"journal":{"name":"Ecohydrology & Hydrobiology","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140047782","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}

Hence, it is necessary to clarify the distribution of comammox bacteria in water bodies. Aquatic plants, whose roots can provide favorable conditions for nitrification, are often used to remediate polluted lakes. This study investigated the community structure of comammox bacteria in the rhizosphere of four aquatic plants in Lake Yuehu, an urban eutrophic lake. The results showed that the abundance of comammox bacteria in the near-rhizosphere of most aquatic plants was higher than that in the far-rhizosphere, suggesting that the aquatic plants promote the rhizosphere abundance of comammox bacteria in eutrophic lakes. Both clade A and clade B of comammox bacteria were present in the Lake Yuehu, with the former showing greater dominance. Co-occurrence network analysis revealed that two subclades of clade A had opposite network parameters in the near-rhizosphere and far-rhizosphere. Redundancy analysis (RDA) analysis showed that OM, pH and NON of sediment were correlated with the abundance of comammox bacteria, which were the main environmental factors affecting the growth of this microorganism. These results suggest that aquatic plants affected the distribution and diversity of comammox bacteria in sediments, which may result in changes in the process of ammonia oxidation and eutrophication in water.","PeriodicalId":56070,"journal":{"name":"Ecohydrology & Hydrobiology","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140044858","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}

This contribution reports a detailed assessment of the status of water quality data of the Cesar River, one of the main tributaries of the Magdalena River, which is regarded as the largest river system in Colombia. Our assessment indicates that the data is limited (in terms of length of record and resolution spatial) and exhibits significant information gaps, and that it is collected through a network of very sparse ground stations with deficient density. Subnational permissible limits for the five main water quality parameters (i.e., pH, TP, TN, DO, TSS) determine that water has reached worrisome levels of pollution. The data limitations does not allow for establishing the influence of natural (e.g., soil erosion) or anthropogenic processes such as wastewater discharges and in-channel sand mining into water quality. Since Colombia is a member of the Pacific Alliance and the Organisation for Economic Co-operation and Development (OECD) the associated supranational water quality regulatory frameworks are analyzed as they may guide the permissible limits and targets in the coming years. A freely accessible database of water quality observations between the years 2004–2020 of the Cesar River accompanies this contribution. We believe that it potentially constitutes a scientific input to plan for restoring the ecosystem services of the Cesar. We also believe this study depicts a representative case of the status of several rivers from the Latin American sphere and other developing countries.","PeriodicalId":56070,"journal":{"name":"Ecohydrology & Hydrobiology","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140044758","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}

It is important to identify processes determining their origin, pathways, distribution, and seasonal dynamics. This was studied in the Vistula Lagoon, second largest lagoon of the southern Baltic. A significant effect of wind on the magnitude and variability of concentrations of metals in the shallow lagoon was observed. It determined the supply of the elements from land (mainly Mn, Zn, U, Co) and distribution within salty Baltic waters (Co, V) from more polluted areas. Another process affecting circulation of metals in estuaries was flocculation. It contributed to vertical transport of Pb, Al, Fe, Mn, Cd, and Be to the sediment surface. Changes in their concentrations were observed, largely due to their remobilisation from land and sediments. It may consequently allow their inclusion into the food-web, particularly: Pb, U, Co, Be, Zn, Se, Cr, Sr, Ca, Al, Fe, Ni and Mg. The amount and type of accumulated metals in the cells were different for each phytoplankton group and cell size. The critical role was played by cyanobacteria algae . Not consumed degrading organic matter becomes a source of dissolved Pb, Ni and Mn in water.","PeriodicalId":56070,"journal":{"name":"Ecohydrology & Hydrobiology","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140044753","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}

To fill this knowledge gap, a study was conducted on five streams in the southwest ecoregion of Nigeria between December 2019 and October 2021. A total of 2,077 macroinvertebrates were sampled, comprising 16 orders, 40 families, and 80 species. Aquatic insects were the most abundant, constituting 85 % of species and 73.13 % of individuals. Other specimens included Mollusca, Crustacea, Arachnida, and Annelida. Notably, Olumirin stream exhibited the highest macroinvertebrate abundance, including the stress-sensitive Ephemeroptera-Plecoptera-Trichoptera (EPT) members. The site also had the highest degree of naturalness, widest channel and dissolved oxygen (DO), but lowest electrical conductivity (EC) and total dissolved solids (TDS) compared to the other streams (Abirunmu, Awoosun, Mogimogi, and Aboto), that harbored facultative and stress-tolerant species, indicating varying degrees of disturbances. The bivariate regression analysis confirms that riparian deforestation and land use impact macroinvertebrate distribution in streams as there was an inverse relationship between EPT abundance and forest cover. Also, DO positively correlates with EPT taxa richness but inversely correlates with Coleoptera richness and Hemiptera abundance. As a result, Olumirin stream is proposed as a benchmark for evaluating freshwater ecological integrity in the region. Given the escalating anthropogenic activities in the tropics, urgent collaborative efforts are required to safeguard freshwater biodiversity, protect the riparian corridor of Olumirin stream, and restore impaired streams in the region.","PeriodicalId":56070,"journal":{"name":"Ecohydrology & Hydrobiology","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139678842","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}

However, the impacts of land use/cover changes (LUCCs) on ecosystem service value (ESV) of lake basins remain unclear. Here, we investigated ESV of the Baiyangdian (BYD) region from 1980 to 2020 based on value equivalent method, assessed spatial differences of ESVs using hot/cold-spot mapping method, and explored the impact of LUCCs on ESVs in combination with elasticity coefficients. The results showed that (1) the study area was dominated by marsh (50.53 %), water bodies (21.84 %) and cropland (20.28 %) in 2020. Marsh, forestland and grassland significantly decreased from 1980 to 2010, and cropland rapidly rose reaching a peak. Marsh, grassland and water bodies increased during 2010–2020, while cropland decreased. (2) Total ESV was 3469.14 million yuan in 2020, a decrease of 5.77 % compared to 1980 (3681.41 million yuan), mainly due to the decrease in marsh area. (3) ESV hot spots were mainly distributed in the middle part of the region, consistent with water bodies, and ESV cold spots were mainly distributed on the edges of the region, consistent with cropland. The spatial distribution of ESVs varied widely, with an increasing trend. (4) The elasticity coefficients of ESVs to LULC were all greater than 1, indicating that ESVs responded significantly to LUCCs. Overall, there was a strong temporal and spatial correlation between LULC and ESV. This study will provide valuable references for optimizing land use policies and ecological restoration plans and promoting the improvement of ESVs in shallow lakes.","PeriodicalId":56070,"journal":{"name":"Ecohydrology & Hydrobiology","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139515400","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}

However, the water consumption characteristics of desert species responding to the irrigation regimes are often neglected. By conducting a field test in the Taklimakan Desert Highway shelterbelt, this study examines the sap flow traits of two typical woody halophyte species (Calligonum mongolicum and Haloxylon ammodendron) and how they react to weather conditions and watering practices. Under the same irrigation treatment, the stem flux of C. mongolicum on sunny days was 1.5–5.3 times that on dusty days, while the stem flux of H. ammodendron on sunny days was 3.5–5.5 times that on dusty days. Both species demonstrated some sap flow during the night, representing 14.3%–24.9% and 7.3%–10.4% of the total sap flow for C. mongolicum and H. ammodendron, respectively. H. ammodendron maintained a higher stem flow during daytime and was more drought resistant than C. mongolicum. The daily sap flow patterns of these two species varied, showing both ‘single’ and ‘double peak’ curves depending on the watering conditions. A delay was also observed between the sap flow of these two species and the environmental factors. The factors influencing plant sap flow were found to be in the order of solar radiation, temperature, relative humidity, and saturated water vapor pressure difference. A BP-neural network proved highly effective for accurately simulating the sap flow of these two species.
