Five sites were selected on the Río Agrio river for in situ measurements, water sampling, and epilithic algae collection in different seasons from 2007 to 2018. Water pH increased along the length of the river, the average increase being highest in summer (from 2.5 to 7.0, acidity to neutrality) and lowest in spring (from 2.8 to 4.0, acidity to acidity). Conductivity and nutrient and ion concentrations decreased along the length of the river, showing a seasonal pattern of variation mainly influenced by the hydrological cycle. Epilithic algal biomass varied seasonally along the river, generally increasing in summer and decreasing in spring, with seasonal maximum values at different locations mainly associated with the dynamics of iron precipitation and nutrient availability. Species diversity and numbers were low at the most acidic site (regardless of season), but in the remaining sites these attributes tended to increase during summer–autumn and decrease during winter–spring. Statistical analysis showed that differences between sites responded mainly to the chemical gradient of the river and seasonality. Therefore, seasonal changes in the longitudinal chemical gradient of the river imposed differential, changing conditions on the epilithic algae present in each site, allowing identification of characteristic zones and their respective epilithic algal attributes. In the context of proposed models of ecosystem response to stress, similarities with systems acidified by anthropic activities are discussed.","PeriodicalId":49061,"journal":{"name":"Inland Waters","volume":"11 1","pages":"404 - 416"},"PeriodicalIF":3.1,"publicationDate":"2021-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43793626","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}

In this study we quantified excretion of a selection of macroinvertebrate taxa and measured nutrient uptake metrics in a small Danish forest stream. Macroinvertebrate excretion was measured in situ from February to April 2019, and uptake metrics were measured using short-term nutrient addition experiments on 2 dates in March and June. To calculate area-specific excretion, quantitative benthic samples were taken on the 3 dominating substratum types: sand, gravel-pebbles, and leaf packs. No significant temperature dependency of invertebrate excretion was found over the measured range (0.3–10.3 °C). Average NH4-N excretion rates ranged from 0.027 (Ptychoptera spp.) to 0.097 µg mg−1 h−1 (Paraleptophlebia submarginata) while PO4-P excretion ranged from 0.0077 (Ptychoptera spp. and Nemoura spp.) to 0.0261 µg mg−1 h−1 (P. submarginata). The uptake length increased from 75 to 117 m for NH4 and from 28 to 71 m for PO4 from March to June. Uptake velocity, by contrast, decreased from March (0.63 m h−1 for NH4 and 1.72 m h−1 for PO4) to June (0.13 m h−1 for NH4 and 0.22 m h−1 for PO4). The estimated contribution from excretion from the entire benthic macrofauna to whole-stream net uptake was 3.4% and 8.9% of NH4 and 0.5% and 2.0% of PO4 in March and June, respectively, suggesting that excretion from benthic macroinvertebrates plays a minor role in meeting whole-stream nutrient demand.","PeriodicalId":49061,"journal":{"name":"Inland Waters","volume":"11 1","pages":"396 - 403"},"PeriodicalIF":3.1,"publicationDate":"2021-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44751333","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}

Projections of 3 CMIP5 General Circulation Models (GCMs) were investigated using 2 Representative Concentration Pathways (RCP4.5 and RCP8.5), which respectively represent low/medium and high greenhouse gas emission scenarios. The raw GCM projections are statistically bias-corrected to provide boundary conditions for the 3-dimensional Aquatic Ecosystem Model (AEM3D). A new overturn bias analysis method was developed to evaluate possible bias in the GCM predictors during the observational (historic) period and determined it to be negligible. The modeling results, quantified by the analysis of various limnological parameters (onset and length of mixing and stratification periods, hypolimnion and epilimnion thickness and temperature, Brunt-Väisälä frequency, and Schmidt stability) indicate for RCP4.5 a continuous reduction in winter mixing and complete suppression of mixing by the end of the 21st century, implying a switch from monomictic to weakly oligomictic behavior. Under RCP8.5, the behavior transition occurs abruptly in the late 2050s in the form of a tipping point, followed by intermittent oligomictic behavior and transition to permanent stratification (thermal meromixis) within a decade. The change in behavior occurs because the surface and mixing temperatures significantly increase due to climate warming, whereas the hypolimnion is less affected, partly because of milder warming of cold winter river inflows (underflow) and strengthening stratification. The climate change-induced tipping point for the thermal regime of Maroon reservoir might serve as an indicator of changes in other warm monomictic systems.","PeriodicalId":49061,"journal":{"name":"Inland Waters","volume":"11 1","pages":"315 - 334"},"PeriodicalIF":3.1,"publicationDate":"2021-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20442041.2021.1918510","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46031272","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}

Exploring lake responses to plausible future climate scenarios can provide important information needed to inform stakeholders of likely effects of hydrologic changes on these waterbodies in coming decades. To assess potential climate effects on lake hydrology, we combined a previously published spatially explicit, processed-based hydrologic modeling framework implemented over the lake-rich landscape of the Northern Highlands Lake District within the United States with an ensemble of climate change scenarios for the 2050s (2041–2070) and 2080s (2071–2100). Model results quantify the effects of climate change on water budgets and lake stage elevations for 3692 lakes and highlight the importance of landscape and hydrologic setting for the response of specific lake types to climate change. All future climate projections resulted in loss of ice cover and snowpack as well as increased evaporation, but variability in climate projections (warmer conditions, wet winters combined with wet or dry summers) interacted with lake characteristics and landscape position to produce variable lake hydrologic changes. Water levels for drainage lakes (lakes with substantial surface water inflows and outflows) showed nearly no change, whereas minimum water levels for seepage lakes (minimal surface water fluxes) decreased by an average of up to 2.64 m by the end of the 21st century. Our physically based modeling approach is parsimonious and computationally efficient and can be applied to other lake-rich regions to investigate interregional variability in lake hydrologic response to future climate scenarios.","PeriodicalId":49061,"journal":{"name":"Inland Waters","volume":"11 1","pages":"335 - 350"},"PeriodicalIF":3.1,"publicationDate":"2021-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42315730","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}

Our aim was to assess whether satellite imagery combined with 3-dimensional (3D) modeling can overcome this limitation. We assessed the performance of a 3D model (Delft3D-Flow) and compared simulated temperature to satellite data on Karaoun Reservoir in a semiarid region of Lebanon. Surface water temperatures were retrieved from Landsat 8, atmospherically corrected using a single channel algorithm and adjusted with in situ measurements as a proxy of bulk temperatures. With limited calibration, the model reproduced water level fluctuations, water temperature, stratification, and mixing, with low discrepancies from measurements. Satellite temperatures agreed well with observations and simulations. Satellite temperature distribution across the reservoir exhibited low spatial heterogeneity. The 3D model partly reproduced this spatial distribution of surface temperature and generally was able to simulate the thermal regime of the reservoir with limited datasets for initial conditions and for hydrological and meteorological forcing, and with limited calibration. For validating 3D hydrodynamic models, satellite temperatures constitute a valuable source of data complementary to point measurements. Coupling satellite imagery and modeling can improve operational surveys of poorly monitored lakes and reservoirs and enhance knowledge of their thermal functioning.","PeriodicalId":49061,"journal":{"name":"Inland Waters","volume":"11 1","pages":"302 - 314"},"PeriodicalIF":3.1,"publicationDate":"2021-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20442041.2021.1913937","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47136502","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}

To address this issue, we present an empirical DO depletion model from time-series measurements of hypolimnetic DO and water-column temperature profiles to estimate hypolimnion thickness (H). The model is based on a dataset that includes 3 temperate lakes (Lake Erie, Lake Simcoe, and Eagle Lake) in Ontario, Canada, of varying size and trophic state. We report SOD (mean [standard deviation]; 0.30 [0.07] g m−2 d−1) and HOD (0.08 [0.03] g m−3 d−1) values based on regression fits of (where t is time) and H from these lakes. The model shows that when vertical (through thermocline) and horizontal fluxes can be neglected in the DO budget during summer, SOD and HOD are the first-order parameters driving . The empirical model predicted hypolimnetic DO in the 3 lakes (root-mean-square error [RMSE] of DO < 3.58 g m−3) and was subsequently validated against observations from a fourth lake (Little Silver Lake, Ontario; RMSE of DO = 1.07 g m−3). The model provides insight into the importance of physical characteristics (i.e., 1/H) in the hypolimnetic DO budget and the relative impact of physical transport versus biogeochemical sources and sinks in the DO budget. When the spring turnover DO concentration is known, the model can be used to simulate depletion of DO in the hypolimnion, including the onset of hypoxia, using routinely collected temperature profile data. We suggest that the proposed values for SOD and HOD can serve as estimates for water quality model calibration when no information is available.","PeriodicalId":49061,"journal":{"name":"Inland Waters","volume":"11 1","pages":"351 - 367"},"PeriodicalIF":3.1,"publicationDate":"2021-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20442041.2021.1880244","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46991627","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}

In this study, we confirmed the existence of black-striped pipefish (Syngnathus abaster) in the freshwater Tbilisi Reservoir (the middle Kura Drainage), which had been translocated from the Black Sea Basin. The introduction was in part a result of the local name of the target freshwater reservoir called the “Tbilisi Sea,” which implied a connection with the Black Sea for local hobbyists. S. abaster is expanding its range with or without human help, and introduction of this species is expected in other regions. To address this problem, we made a species distribution model using MaxEnt software to test the species environmental suitability around the globe. Lowland inland waterbodies and shorelines in temperate, Mediterranean, and arid climate zones were indicated as localities where this fish could survive if released. The risk of introduction currently seems low, but exploitation of S. abaster for ornamental purposes due to expanding local and international pet trade increases the likelihood of future releases. For this reason, it is important to verify new cases of successful establishment of this species.","PeriodicalId":49061,"journal":{"name":"Inland Waters","volume":"11 1","pages":"278 - 285"},"PeriodicalIF":3.1,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20442041.2021.1909374","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45080630","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}

High-elevation lakes have been particularly overlooked given their high abundance in mountain ranges around the world, and the potential for CH4 dynamics at high elevations is expected to be disproportionally impacted by increases in temperature due to climate change. We examined variations in surface CH4 concentrations and diffusive fluxes, temperature, and inorganic nutrients in 5 montane lakes spanning multiple elevations in the Sierra Nevada of California. Over 2 years, we found strong and consistent seasonality in CH4 concentrations in lakes; higher concentrations were typically observed in the warmest months and lower concentrations right before winter. Changes in CH4 concentrations were significantly related to temperature in the majority of the individual lakes (r 2 = 0.43–0.81) and related to elevation (r 2 = 0.39) across lakes. Methane concentrations in lakes at elevations <3000 m were strongly related to temperature, nitrite concentrations, and elevation (r 2 = 0.90), whereas at elevations >3000 m, CH4 was related to dissolved inorganic nitrogen to dissolved inorganic phosphorus ratios and elevation (r 2 = 0.48). Our results expand our understanding of temporal variations in CH4 and demonstrate substantial seasonality in CH4 concentrations and diffusive fluxes in freshwater lakes. We suggest that temporal variation should be considered in large-scale estimates of CH4 emissions, and these fluxes may be a predictable function of elevation, temperature, and nutrients.","PeriodicalId":49061,"journal":{"name":"Inland Waters","volume":"11 1","pages":"267 - 277"},"PeriodicalIF":3.1,"publicationDate":"2021-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20442041.2021.1903287","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47813325","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}

Climate exerts a significant influence on mechanisms of OC capture, storage, and processing on the wet and cloudy west coast of Ireland. We examined a high-frequency dataset of partial pressure of CO2 (pCO2) in the surface waters of Lough Feeagh collected over 1 year. The annual pattern in pCO2 ranged between 491 and 1169 µatm and was strongly related to allochthonous riverine OC inputs. In contrast to observations in colder climates, a single peak in pCO2 occurred in Lough Feeagh in early September. Generalised additive mixed modelling revealed that 2 variables, inflow water colour concentration (a reliable proxy for DOC concentrations) and lake Schmidt stability, together explained 68% of pCO2 variability. Both the statistical analysis and timing of the peaks in inflow DOC and pCO2 strongly suggested that catchment carbon export drove pCO2 supersaturation in the lake, and hence CO2 emissions. We estimated that between 217 and 370 t CO2-C (0.55–0.94 t/ha) was emitted during the study period.
