We investigated the structure, diversity, and gene functions of bacterial communities in 3 reservoirs in Yun-Gui Plateau. We assumed the bacterial community structures were different among these 3 plateau reservoirs because of differences in trophic status. We found an insignificant difference in bacterial community structure among the reservoirs but a varying relative abundance of components in the community. Proteobacteria and Cyanobacteria were the most abundant phyla. Alpha diversity, as indicated by Simpson, Shannon, and evenness indexes, were similar in the 3 reservoirs, but richness was different. Hongfeng Reservoir exhibited the lowest heterogeneity, as indicated by the beta diversity. Analysis of gene functions suggested that amino acid metabolism and membrane transport were important and reflected the multiple roles of bacteria in biogeochemical processes. This study provided information about the bacterial community structure in reservoirs of Yun-Gui Plateau and analysis of the effects of environmental factors. Bacterial communities show little variation among reservoirs due to exposure to similar environmental conditions, and differences in trophic status were not a strong driver of community structure changes.","PeriodicalId":49061,"journal":{"name":"Inland Waters","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2023-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47427240","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}

Cyanobacteria forecasting models are typically complex, requiring input of biophysical and chemical measurements or DNA sequencing in situ. Satellite imagery presents a unique opportunity to estimate cyanobacteria concentration directly at low cost and over wide spatial and long timescales. This study explores the hypothesis that simple univariate forecasting methods can reliably forecast cyanobacterial blooms in the near-term (1 week ahead) detected using satellite remote sensing. A simple univariate model based on logical decomposition with a moving average and seasonal component was developed to forecast chlorophyll a concentrations from cyanobacteria and algal blooms in lakes using spatially aggregated satellite remotely sensed data. A small test set of 15 spatially distributed waterbodies was used to assess forecast performance on 1-week, 2-week, and 4-week forecast horizons using a year-long hold-out time series. For a 1-week time horizon, cyanobacterial blooms posing a high health risk could be forecast with 80% accuracy. The 2-week and 4-week forecast accuracy dropped to 71% and 69%, respectively. Forecast performance was only weakly influenced by lake size, suggesting that the spatial-aggregation approach may be valid even for large lakes. Additionally, longer time series reduced the observed forecast error, presumably because of better seasonal characterization. This study is the first to demonstrate that simple univariate models with remotely sensed time series can forecast cyanobacteria and HABs with almost the same reliability as complex models.","PeriodicalId":49061,"journal":{"name":"Inland Waters","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134946508","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}

By contrast, few studies have focused on ephemeral wetlands, primarily represented by extremely ephemeral rock pools. In Central Europe, many ephemeral wetlands develop spontaneously directly on arable land, often on the sites of former natural wetlands that have been drained and converted to agricultural land. Here, we focused on aquatic invertebrates in 10 ephemeral pools over periods of inundation to desiccation on arable land in southern Moravia. Despite relatively short hydroperiods of 5–11 weeks, we observed significant changes in community composition, including species replacement. Dynamics differed between macroinvertebrates and microcrustaceans and between different macroinvertebrate feeding and dispersal groups. Predation pressure increased over time and was highest during drying. Passive dispersers were most abundant during the middle phase, whereas the abundance of active dispersers increased throughout the hydroperiod. Because no significant effect of any environmental factor was detected on community change, we hypothesized that community dynamics were driven by differences in species traits and biotic interactions rather than by the changing environment. This study fills a knowledge gap on the temporal dynamics of aquatic invertebrate communities in temporary wetlands by investigating wetlands with short, but not extremely ephemeral, hydroperiods.","PeriodicalId":49061,"journal":{"name":"Inland Waters","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2023-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49247580","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}

These lakes, which are heavily utilized for aquaculture and ecotourism, usually experience fish kills that coincide with the northeast monsoon (NEM). This study explores limnophysical processes, particularly mixing regimes, in the lakes in relation to prevailing monsoons. We monitored monthly vertical and seasonal profiles of water temperature, salinity, conductivity, and dissolved oxygen from October 2016 to December 2018. Three types of mixing regimes were observed among the lakes, which have similar surface areas but different depths: polymixis in the shallowest; warm monomixis in lakes with intermediate depth; and meromixis in the deepest. A boundary between monomixis and meromixis was identified between 36 and 62 m depth. Monthly monitoring showed seasonal mixing occurred exclusively during the NEM (Nov–Apr). We also incorporated meteorological data into the model and performed multiple regression analysis for each lake to determine the best predictor: lake stability, as indicated by the Schmidt stability (ST ). A between-lake comparison showed lake stability was strongly correlated with both air temperature and wind speed, suggesting these 2 meteorological variables are involved in establishing thermal stratification in the lakes during the southwest monsoon. This study provides insights for adaptive lake management and projections of climate impacts on these understudied tropical lake ecosystems in Southeast Asia.","PeriodicalId":49061,"journal":{"name":"Inland Waters","volume":"13 1","pages":"47 - 61"},"PeriodicalIF":3.1,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44176413","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}

Sensor deployments at fixed depths in naturally formed lakes dominate the current understanding of ecosystem dynamics, with comparatively few studies focusing on reservoirs. Here we examined how environmental parameters affect the water column stability and dissolved oxygen (DO) dynamics in a North Texas eutrophic reservoir. We used an autonomous water quality monitoring profiler that recorded temperature, DO, and pH as well as wind speed, wind direction, and air temperature from an on-platform mounted weather station. Data were collected every 2 h from 25 April to 29 October 2019, with each profile spanning from the surface to 10 m depth at 0.5 m steps. Throughout most of the sampling period, the lake had no distinct thermocline, but we observed an oxycline throughout most of the monitoring period, with multiple mixing events. Near the sediments, periods of anoxia lasting hours to days were first observed in May, and July through September were chronically anoxic. In August and September, DO was frequently <2.0 mg L−1 throughout the entire water column, with 2 periods of total water column anoxia. Surface DO measurements for each 2 h interval were highly synchronous with Schmidt stability. During decreasing and low Schmidt stability or Lake Number, the oxycline destabilized in association with changes in wind direction and speed. Our results indicate that DO can be highly dynamic in polymictic reservoirs, with strong implications for carbon and nitrogen biogeochemical cycles.","PeriodicalId":49061,"journal":{"name":"Inland Waters","volume":"1 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41722609","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}

While the extinction of macroscopic organisms has been well documented in the scientific literature and public media, we have only limited knowledge on the loss of microscopic elements of the ecosystems. Because rarity coincides with the increased risk of extinction, we investigated the commonness and rarity of microalgae in the Pannonian ecoregion. We reviewed the published literature of microalgal research in Hungary over the last 140 years and created a species-by-site matrix containing 2489 algae species and 1145 localities. Analysing this dataset, we found that although the core-satellite hypothesis suggests a bimodal site occupancy distribution, microalgae displayed a unimodal pattern with a high number of rarely occurring species. We also demonstrated that the well-known negative relationship between body size of organisms and number of occupied habitats holds for microalgae. Rarity values of taxa have a phylogenetic signal indicating that in terms of rarity, closely related species (desmids, dinoflagellates, euglenophytes) show considerable similarities. The various habitat types showed differences in the number of rare taxa. Small- and medium-sized habitats (bog lakes, streams, oxbows) hosted the majority of rare species. These results highlight the conservation importance of small habitats in preserving microbial diversity.","PeriodicalId":49061,"journal":{"name":"Inland Waters","volume":"1 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2022-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44062010","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}

The lake is an important site for millions of migratory birds that feed on 2 principal invertebrates, brine shrimp and brine flies (Diptera: Ephydridae). Despite their ecological and economic importance, no genetic studies have been published for either resident GSL invertebrate. The family Ephydridae (shore flies and brine flies) is one of the largest in the order Diptera, with nearly 2000 described species. Members of this family are prominent in a variety of aquatic environments and are particularly interesting because of their adaptation to several marginal habitats, including hot springs, oil ponds, highly saline lakes, and inland alkaline pools and marshes. This report provides cytochrome c oxidase I (COI) DNA barcodes for 5 species of GSL shore flies, distributed among 5 genera and 3 subfamilies. The phylogenetic content of these DNA sequences is explored by comparing a molecular phylogeny to those based on morphological features. Over the past decade, urbanization and inflow diversion have reduced the surface area of GSL by nearly 50%, with unknown consequences for the ecosystem. This study establishes a genetic framework to assess changes in GSL invertebrate diversity important in monitoring the effects of anthropogenic and climate pressures on this important natural resource.","PeriodicalId":49061,"journal":{"name":"Inland Waters","volume":"13 1","pages":"101 - 110"},"PeriodicalIF":3.1,"publicationDate":"2022-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44553261","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}

The aim of this study was to provide the first limnological characterization of shallow (∼1–2 m depth) lakes in the Scotty Creek basin (Northwest Territories, Canada), a field site of circumpolar significance due to the existence of long-term ecohydrological monitoring going back decades. We use this previous work as a foundation to advance our process-based understanding of the potential drivers of lake ecosystem change. Our results showed that dissolved organic carbon (DOC) and lake color were not correlated, a pattern that seems to be an important driver of diatom (siliceous single-celled algae) assemblages in these lakes. Diatoms in the study lakes tended to fall into 1 of 2 assemblage clusters. One cluster, composed of small benthic Fragilariaceae and small Navicula species (sensu lato), was found associated with higher lake color; the second cluster, composed of Encyonopsis and large Navicula species, was found associated with high DOC, lower color, and the presence of a benthic moss mat. From this finding, we suggest that DOC quality is a primary control on lake ecology in this region for its role in controlling light penetration to the lake bottom. Our hypothesis that the prevalence of nearshore fens and collapse scar wetlands would be important drivers of DOC was not supported in the 9 study lakes with available data to map shoreline features.","PeriodicalId":49061,"journal":{"name":"Inland Waters","volume":"13 1","pages":"13 - 29"},"PeriodicalIF":3.1,"publicationDate":"2022-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48186697","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, permanent and pristine spring fens in the Western Carpathians show between-site variation in thermal stability with significant effects on macroinvertebrate assemblages. In this study, we investigated the impact of the thermal stability on microcrustaceans (Harpacticoida, Ostracoda). We disentangled various parameters of thermal stability, such as mean summer and winter temperatures, annual amplitude, and daily fluctuations, and related these parameters to mesoclimate, vegetation cover, and water table. We found that the relative abundance of cold-stenothermal species decreased significantly with increasing mean water temperature in summer, which had a significant effect on species composition. Surprisingly, ostracods were completely indifferent to thermal stability despite including cold stenotherms and crenobionts, suggesting that these species might have broader thermal tolerance. By contrast, harpacticoids significantly responded to both summer and winter mean temperatures, showing upper and lower limits of thermal tolerance. While vegetation cover significantly suppressed daily fluctuations in summer, no effect of daily fluctuations on microcrustaceans was found. The effect of water table was also significant but independent of thermal stability. We assume that the less thermally stable sites will not support the occurrence of cold-stenothermic harpacticoids as air temperature rises. However, an increase in winter temperatures may result in higher overall abundance of harpacticoids. We discuss how spring fens are probably most threatened by the combination of drought and increasing temperature.","PeriodicalId":49061,"journal":{"name":"Inland Waters","volume":"13 1","pages":"86 - 100"},"PeriodicalIF":3.1,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43506309","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}
