Here, we evaluated LCBD and SCBD of aquatic macrophyte metacommunities from 29 subtropical coastal wetlands, covering an extension of 640 km, in Southern Brazil. Furthermore, we assessed the environmental uniqueness, considering both the physical and chemical variables of water in wetlands, as well as climatic variables. We assessed the environmental and spatial correlates of LCBD and the environmental correlates of SCBD. We expected that (i) communities with greater compositional uniqueness would be found in environmentally more unique wetlands, (ii) the compositional uniqueness would also be related to climatic variables that determine the hydrological changes in wetlands, and (iii) the contribution of emergent species to beta diversity would be lower than of floating and submerged species. The compositional uniqueness did not present a clear spatial structure, being positively related to uniqueness in water chemistry and negatively to the mean air temperature during the driest quarter. The species contribution to beta diversity was higher for floating species than for emergent ones. Moreover, SCBD correlated to climatic variables and presented a positive relationship with site occupation, suggesting that more frequent species in terms of site occurrence contribute most to beta diversity. Our results show the importance of local environmental and broader climatic predictors in determining the compositional uniqueness of macrophyte communities and species contributions to overall beta diversity in the coastal wetlands of Southern Brazil.</p></div>","PeriodicalId":55489,"journal":{"name":"Aquatic Sciences","volume":"86 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141938291","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 investigated benthic algal communities in the upper Red River Basin in China. We collected data on land use, topography and other factors at the watershed scales to gain a comprehensive understanding in the upper Red River Basin in China. Partial canonical correspondence analysis, partial redundancy analysis and variance partitioning analysis methods were used to assess the effects of watershed and local environmental factors on benthic algal communities and their variation. The percentage of landscape that was forest (F-PL), the percentage of landscape that was cropland (C-PL), the percentage of landscape that was water (W-PL), elevation, slope, pH and water level fluctuation (WF) were identified as significant factors affecting the distribution of benthic algal communities. The diversity of benthic algal communities were greatly affected by environmental factors as F-PL, W-PL, precipitation (Prcp), slope, permanganate index (COD_Mn) and index of substrate (IOS). Slope, F-PL and Prcp showed a positive correlation with species evenness and a negative correlation with community density. The characteristics of functional groups of benthic algae were also shown to be strongly influenced by C-PL and IOS. According to the variance decomposition (VPA) results, it can be seen that, although the explanatory power of individual local and watershed environmental factors was roughly similar, their joint explanatory power was relatively low. Therefore, the influence of watershed environmental factors on benthic algal communities should not be overlooked.</p></div>","PeriodicalId":55489,"journal":{"name":"Aquatic Sciences","volume":"86 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141938333","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 general, many natural and/or man-made activities have strongly stressed the Egyptian Nile estuarine habitats, as has the water shortage that was expected after the construction of the Grand Ethiopian Renaissance Dam. In recent decades, the Nile Delta has been considered to be one of the most important productive oil-producing petroleum regions due to onshore and offshore gas discoveries alongside gasoline and base oil generation. Up-to-date systematic reviews of the Egyptian estuarine habitats (Rosetta and Damietta) are missing, and the review reported here was undertaken to fill this gap. In this review, we consider the physical, chemical, geological, pollution, and biological parameters of Egyptian Nile estuaries. In this context, our aim is to contribute to a broader understanding of the Egyptian estuarine habitat; moreover, we provide potential warning signals that may aid in estuarine environmental protection. We found that most of the previous studies had focused on the two branches of the Nile or on the marine waters adjacent to these branches, and that only a few studies focused on the estuarine habitats themselves. In most of these previous studies, the salinity gradient of water was reported to be a significant factor in the distribution of the different measured parameters while, in contrast, more recent investigations confirm the importance of potential effluent sources in affecting the distribution of these parameters. We highly recommend that the data reported here be updated in future studies on different environmental aspects.</p></div>","PeriodicalId":55489,"journal":{"name":"Aquatic Sciences","volume":"86 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00027-024-01111-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141938332","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}

Microplastics enter waterways from a variety of sources, although the relative importance of point and nonpoint sources for a given watershed is not well understood. To determine whether medium-sized wastewater treatment plants are significant sources of microplastics to rivers draining into Lake Erie, we measured microplastic loads up- and downstream of two wastewater treatment plants in southeastern Michigan State (USA). We detected a significant increase in the microplastic load downstream from the wastewater treatment plant discharging into the Lower Rouge River, but not downstream from the one discharging into the Huron River. However, the background microplastic load was tenfold higher in the Huron River compared to the Lower Rouge River, likely obscuring our ability to detect the wastewater treatment plant as a point source. We found a positive relationship between river discharge and microplastic load in the Huron River, which drains a larger watershed area at the effluent discharge point than the Lower Rouge site, suggesting that watershed sources may be more important over larger spatial scales. We also performed experiments to test the effects of plastic on stream biofilm function to better understand how plastic pollution alters stream metabolism. Biofilms grown on high-density polyethylene and polypropylene had significantly lower metabolic diversity and metabolic response, respectively. Overall, our findings indicate that attention should be directed to both point and nonpoint sources to reduce microplastic pollution and that plastics may negatively affect the function of stream biofilm communities.</p></div>","PeriodicalId":55489,"journal":{"name":"Aquatic Sciences","volume":"86 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141886629","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}

Assessing the response of phytoplankton—the basis of marine food webs—at the early stages of an oil spill and throughout its evolution is crucial to improve our understanding of the impact of oil spills on the marine environment. Field data collected 1, 4, 8, and 18 days after the “Bizerte City” oil spill showed that phytoplankton responded differentially over time. In the short term (1–8 days), picophytoplankton biomass and abundance increased, possibly owing to reduced grazing. In contrast, nano- and microphytoplankton biomass decreased, probably owing to inhibited growth of species sensitive to polycyclic aromatic hydrocarbons (PAHs)—the most toxic components of oil. After 18 days, the dispersal of oil and its decreasing negative effect were accompanied by outbreaks of all size fractions. Accordingly, the phytoplankton size structure shifted throughout the oil exposure level from a prevalence of microphytoplankton after a few days toward picophytoplankton dominance. Oil pollution influenced the species composition and significantly decreased diversity indexes. In the first days, nanophytoplankton was dominated by Cryptophyceae (mainly <i>Hillea fusiformis</i> and <i>H</i>. <i>marina</i>), while microphytoplankton was mostly represented by the pennate diatoms <i>Pseudo-nitzschia</i> and <i>Nitzschia</i>, suggesting a better resistance of these genera to oil. Algal recovery after 18 days was associated with high proliferation of nano-sized <i>Chaetoceros</i> and micro-sized <i>Astrionellopsis glacialis</i> diatoms. These results improve our knowledge of the impact of oil pollution on coastal phytoplankton communities and reinforce the idea of using them as bioindicators.</p></div>","PeriodicalId":55489,"journal":{"name":"Aquatic Sciences","volume":"86 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141868304","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 area has been non-glaciated for decades, although rock glaciers are still present in the south basin. Surface waters, 10 stream sites in the present study, have been monitored in mid-summer since the year 2001 for physico-chemistry, periphyton and macroinvertebrates (including 74 species of chironomids). Water physico-chemistry revealed that the two main basins in the catchment differed, reflecting the inputs of rock glacier waters in the south basin. However, trends suggest that waters are becoming more similar as rock glacier inputs diminish over time along with a general decrease in nitrogen levels in all waters. Periphyton biomass showed some spatial differences among sites and a general decrease after 2010. Macroinvertebrate assemblages, including chironomids, clearly differed among basins and spatially along the stream network in each basin. Notably, no significant temporal trend was observed in the long-term data for macroinvertebrates, including chironomids, at the monitored sites.
