For the meta-analysis, 27 articles met the selection criteria and a total of 168 effect sizes were calculated. The results from the generalized linear mixed models (GLMMs) indicated that the hydrocarbons have the strongest effect in polychaetes, while the most sensitive metric is behavior. Enzymatic activity and mortality represented the most sensitive biological responses to estimating the magnitude and direction of the effect.

In this study, the dissolved REE concentrations were measured in the river and estuary of the Jiulong River, which supplies drinking water to about one-third of the population of southern Fujian Province. The results showed the total dissolved REE varied within a wide range, from 19.94 to 2041.58 ng/L. (La/Yb)<sub>N</sub> varied between 0.15 and 1.03 in the Jiulong River, and apparent fractionation between LREE (depleted) and HREE (enriched) was noticed, especially at the estuary. The fluctuations of dissolved REE concentrations were mainly related to the riverine pH and the complexation with colloids and ions. Higher dissolved REE concentrations in the Xixi River were attributed to the application of chemical fertilizer. The relatively lower concentrations in the estuary may result from salt-induced flocculation, and the preferential removal of LREE resulted in lower (La/Yb)<sub>N</sub> and more pronounced HREE enrichment in the estuary. The Ce anomalies observed in the Jiulong River were associated with redox conditions, while positive Eu anomalies were linked to the dissolution of the rocks within the basin. The distinct Gd anomalies were observed in N4 and W10 flowing through the urban area, suggesting the point source inputs from the wastewater associated with anthropogenic activities. This study highlights the effect of natural processes and human activities on dissolved REE in fluvial-estuarine systems, which should raise concerns regarding anthropogenic inputs of REE to rivers and coastal regions.</p></div>","PeriodicalId":8262,"journal":{"name":"Aquatic Ecology","volume":"57 3","pages":"765 - 781"},"PeriodicalIF":1.8,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41274865","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}

Currently, morphology measurements mostly happen manually and sometimes in conjunction with individual fish imaging, which is a time-consuming and expensive procedure. In addition, extracting useful information such as fish yield and detecting small variations due to growth or deformities, require extra offline processing of the manually collected images and data. Deep learning (DL) and specifically convolutional neural networks (CNNs) have previously demonstrated great promise in estimating fish features such as weight and length from images. However, their use for extracting fish morphological traits through detecting fish keypoints (landmarks) has not been fully explored. In this paper, we developed a novel DL architecture that we call Mobile Fish Landmark Detection network (MFLD-net). We show that MFLD-net can achieve keypoint detection accuracies on par or even better than some of the state-of-the-art CNNs on a fish image dataset. MFLD-net uses convolution operations based on Vision Transformers (i.e. patch embeddings, multi-layer perceptrons). We show that MFLD-net can achieve competitive or better results in low data regimes while being lightweight and therefore suitable for embedded and mobile devices. We also provide quantitative and qualitative results that demonstrate its generalisation capabilities. These features make MFLD-net suitable for future deployment in fish farms and fish harvesting plants.</p></div>","PeriodicalId":8262,"journal":{"name":"Aquatic Ecology","volume":"57 4","pages":"913 - 931"},"PeriodicalIF":1.8,"publicationDate":"2023-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10452-023-10044-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41606821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

The aim of this study was to determine the impact of shoreline and buffer zone development on the attributes of rushes. Indications of lake features affected the rushes most strongly. We analysed 65 lakes located in the eastern part of Poland, within the boundaries of the Łęczna-Włodawa Lake District. The multidimensional analyses identified factors that most strongly determined the development of lake rushes in Polesie Lubelskie. The presence of peat bogs, scrubland communities, and wet meadows favoured the development of rushes. Among the morphometric characteristics of lakes, the depth and frequency of water mixing were significant, as well as the trophic level of the lake. Moreover, models describing scenarios for further development of rushes were developed. They predicted that the surface area of the rushes in the lake will increase (average of 0.288 ha) when the peatlands become overgrown 1 ha, and the share of dry (drained) meadows will increase (average of 0.996 ha) in the buffer zone. The increase in the density of rushes will take place if the share of buildings and scrub communities increases both in the buffer zone and shoreline area.</p></div>","PeriodicalId":8262,"journal":{"name":"Aquatic Ecology","volume":"57 3","pages":"633 - 652"},"PeriodicalIF":1.8,"publicationDate":"2023-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10452-023-10034-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42158734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Seasonal variation was found to drive diatom assemblage composition and cellulose decomposition among seasons. Moreover, there were clear seasonal patterns in taxa succession in the diatom assemblages where the dominant taxa shifted in accordance with ecological preferences of the taxa. Within season assessments of stream biofilms among individual reaches showed that biomass, diatom assemblage composition, and cellulose decomposition were not associated with amount of groundwater input. The lack of concordance between groundwater influence and stream biofilm condition suggests that the groundwater signal may have been overwhelmed by surface water influences, such as nutrients and thermal effects, at the reach scale.

This work aimed to determine the effects of green areas and the urbanization process in the natural populations of <i>S. fuhrmanni</i> in the mountains of Manizales (Colombia) and whether different types of green areas serve as the refuges for the species. For the occurrence records, collections were carried out through active search in streams, and specimens from the biological collection were analyzed. An analysis of niche modeling and quantification of environmental spaces in the city was carried out, based on the occurrences of the species in the streams. The modeling showed that <i>S. fuhrmanni</i> was widely distributed in the streams of Manizales city; however, the fragmentation of the environment, through urbanization, restricted the population. Regarding the quantification of environmental spaces, this species is occupying less than 50% of its original area. Finally, we emphasize the importance of the green spaces for the remaining populations of <i>S. fuhrmanni</i>, as the streams are still conserved in these areas and provide conditions for their occurrence. Given the rapid urbanization process, it is important to study biodiversity inside these areas to understand how this process affects species, in special endemic ones.</p></div>","PeriodicalId":8262,"journal":{"name":"Aquatic Ecology","volume":"57 3","pages":"733 - 745"},"PeriodicalIF":1.8,"publicationDate":"2023-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41531184","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}
