We measured water quality variables and benthic diatom and macroinvertebrate assemblages to evaluate the ecological status of the canal. We found that the canal was eutrophic with an average chemical trophic level index of 64.3 and an average trophic diatom index of 68.1 (with <em>Nitzschia palea</em>, <em>Melosira varians</em>, and <em>Navicula rostellata</em>, <em>Encyonema minutum</em> abundant). Macroinvertebrate assemblages also showed that the canal was eutrophic based on the dominance of <em>Limnodrilus</em> sp. A low BMWP (Biological Monitoring Working Party) score further indicated the poor water quality of the canal. Correlation analysis indicated that phosphorus was the main driver of eutrophication in the canal. Consequently, more attention should be paid to reduce phosphorus loadings.</p></div>","PeriodicalId":101277,"journal":{"name":"Water Biology and Security","volume":"3 1","pages":"Article 100231"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772735123001269/pdfft?md5=f3dd100cddf5786373d96bf1a0f5829a&pid=1-s2.0-S2772735123001269-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136128273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there have been few studies focused on how FABs impact other aquatic organisms, especially in alpine lakes since these are at the forefront of responding to global climate change.

Significant seasonal changes in phytoplankton biomass and β diversity were observed in zones with <em>Cladophora</em> blooms.

The basic reproduction number <em>R</em>_<em>0</em> was derived by the model parameter including the water transmission coefficient and was used for the analysis of the virus transmission. Spring viremia of carp virus (SVCV) and zebrafish were used as model viruses and animals, respectively, to conduct the transmission experiment.

This study is of significance in providing theoretical guidance for minimizing <em>R</em>_<em>0</em> by manipulating model parameters with containment measures.

Biotic diagnostic assessments are still in the exploratory stage and can only diagnose possible stressor types and wide-ranges of their intensities through empirical models linking stressors and species-trait-indices. Current chemical integrity assessments mainly use criteria determined by small-scale ecotoxicity tests, rather than quantitative relationships developed between chemical factors and biotic effects in real ecosystems, thus potentially under or over-estimating pollutant toxicity. Current physical integrity assessments focus on overall habitat quality, rather than quantitative habitat requirements, and thus cannot provide quantitative support for ecological restoration and conservation. Current hydrological integrity (environment flow) assessments largely depend on quantitative relationships between hydrological regimes with a few species and single groups, rather than with whole communities, and fail to comprehensively diagnose hydrological causes of biotic resource decline. In the future, integrity assessments need to be based on ecosystem integrity requirements of ecosystem service targets: first, there is a need to build quantitative relationships between biotic integrity and ecosystem services, assess requirements of community structure and function for service goals, and establish biotic integrity assessment methods; second, we must build quantitative relationships between biotic integrity and abiotic integrity in real ecosystems, assess chemical, physical, and hydrological integrity requirements of biotic needs, and establish diagnostic assessment methods.</p></div>","PeriodicalId":101277,"journal":{"name":"Water Biology and Security","volume":"3 1","pages":"Article 100230"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772735123001257/pdfft?md5=2d36d61e0478db28b52efb454f9c682a&pid=1-s2.0-S2772735123001257-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136011001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study quantitatively investigated the sperm motility of male swamp eels during the breeding season by using computer-assisted sperm analysis system. Variability in the proportion and number of motile sperm was observed between individual males. The testes were grouped into high-quality and low-quality according to sperm quality. Morphometric parameters of the two groups were analyzed. We found that high-quality testes were longer (150 ​± ​27 ​mm verses 127 ​± ​19 ​mm) than low-quality testes. Besides, the proportion of testes with a dark appearance was slightly higher (58.3% verses 48.1%) in the high-quality group than in the low-quality group. Metabolomic analysis was conducted to compare the metabolite profiles of high-quality and low-quality testes. Glycerophospholipids, organic acids, glycerolipids, amino acids, sphingolipids, and nucleotides were the most abundant metabolites in the testes of swamp eels. Moreover, 135 differential metabolites were identified.

Ecological stoichiometry provides a conceptual framework that explains this trophic interaction using C, N and P elemental composition across trophic levels. In light of ongoing climate change and eutrophication, previous studies have raised concerns regarding the growing stoichiometric mismatch between phytoplankton and zooplankton, given the stoichiometric plasticity of phytoplankton. However, there is currently little conclusive evidence on the stoichiometric mismatch from a dual perspective of phytoplankton and zooplankton. To address this, we conducted a mesocosm experiment to investigate the separate and combined effects of climate warming (a constant increase of +3.5 ​°C plus heat waves) and eutrophication (nutrient addition) on stoichiometric mismatch between phytoplankton and zooplankton by examining stoichiometric changes in both communities. We observed a growing trend in stoichiometric mismatches when warming or nutrient addition acted individually, which was mediated by the increase in nutrient demand (N, P elements) of zooplankton growth. However, when these stressors acted jointly, the mismatches were reversed. This could be because climate warming and eutrophication combined would lead to changes in species composition, which accordingly reshaped the stoichiometric composition at the community level. These results illustrate the need of stoichiometric mismatches for understanding the implication of global change on trophic interactions and ecosystem functioning, requiring consideration not only of cross-trophic levels but also of compositional changes within communities.</p></div>","PeriodicalId":101277,"journal":{"name":"Water Biology and Security","volume":"2 4","pages":"Article 100205"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49713359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Yangtze finless porpoise (<em>Neophocaena asiaeorientalis asiaeorientalis,</em> YFP) is one of the smallest cetacean species worldwide, which exclusively inhabits the middle and lower regions of the Yangtze River in China. Here, we investigated BT variation patterns in YFPs and their relationship to environmental temperature changes using ultrasound imaging technology by longitudinally monitoring four YFPs in human care. We found that blubber was not evenly distributed in the skin of YFPs. BT increased along the craniocaudal axis from the head to the umbilical girth, and decreased towards the fluke, with relatively thicker blubber in the dorsal region than in the ventral and lateral regions. Significant negative correlations between BT and seasonal water temperature changes were observed in YFPs. However, different body regions display different sensitivities to seasonal temperature changes. The BT in the anal girth region exhibited noticeable seasonal changes. In contrast, the umbilical lateral and ventral regions showed relatively blunt seasonal changes, indicating different adaptive functions of the blubber in different regions. BT in the dorsal region decreased linearly with increasing water temperature. In the lateral and ventral regions, BT significantly changed with water temperature at a threshold of 18 ​°C. The YFPs had relatively thinner BT than similar-sized harbor porpoises that inhabit relatively high latitudes with much lower water temperatures. This further demonstrates the adaptive function of BT in response to environmental temperatures in small cetaceans.
