In this regard, the application of biological soil crusts is regarded as one of the biological and environmentally oriented methods to improve the soil hydrological behavior, cohesion, aggregation, and erodibility in such a way as to withstand destructive agents for soil and water loss. Despite general agreement on the beneficial effects of microorganisms in reducing soil loss and runoff, no unique conclusion has been drawn to minutely report the extension and consequences of applying soil microorganisms in soil and water conservation. In the current endeavor, out of too many reports found following insight searches in the public domains, 77 journal papers published from 1990 to 2023 on the relationship between microorganisms on soil loss and runoff control were ultimately reviewed. Accordingly, the first successful research was reported in 2003. Our further inspections showed that more than 90 % of the investigations had been conducted in China, Spain, Iran, the United States, Palestine, and the west of the Jordan River. In 82 % of the internationally published investigations, the application of cyanobacteria for conserving soil and water resources has been either preferred or recommended. Overall, the outcome of our inspection showed that microorganisms have been effective in controlling runoff and soil loss, due to which a global increasing tendency to extend soil microorganisms-based approaches is seen for soil and water resources management.</p>","PeriodicalId":56070,"journal":{"name":"Ecohydrology & Hydrobiology","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138506831","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}

The aim of this work was to identify the taxonomic resources of the river network of this area and to compare the biodiversity of various aquatic organisms, and moreover, evaluate the field sampling effort required to identify the whole pool of taxa inhabiting the survey area. Fieldwork was carried out in 2021 at 25 survey sites, where the taxonomic compositions of five groups of organisms were identified: benthic diatoms, phytoplankton, macrophytes, benthic macroinvertebrates, and ichthyofauna and identified taxa have been presented in the appendix. The biodiversity indices of these groups were calculated, i.e. the species richness, and the Shannon and Simpson indices. The entire predicted biodiversity of these groups of organisms was also estimated. The Chao2 asymptotic taxonomic richness estimator for incidence data was used to calculate the additional number of survey sites that would be required to discover 80%, 90% and 100% of the anticipated taxonomic richness in each of the five groups of organisms. With the information on the species inhabiting the Biebrza Valley that this survey yielded, the biodiversity at a single site (alpha diversity) and within the entire area surveyed (gamma diversity) was estimated. The phytoplankton (475 taxa) and the benthic macroinvertebrates (308) showed the greatest diversity in taxonomic richness. In addition, there were 151 species in the benthic diatom group, 72 macrophyte taxa, and 24 fish species. The analysis showed, moreover, that if the fieldwork were continued, another 110 phytoplankton and 104 benthic macroinvertebrates taxa would be recorded for BNP, along with 40 further species of benthic diatoms, 9 more macrophyte species, and 2 more fish species. Alpha diversity was found to be high but gamma diversity was relatively low due to the homogeneous nature of the rivers surveyed (low beta diversity), effective conservation measures, and minimal human disturbances.</p>","PeriodicalId":56070,"journal":{"name":"Ecohydrology & Hydrobiology","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2023-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138506833","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}

To what extent will shallow-water fauna be affected by warming? We investigated this issue using an example of one species of colonial hydroid, Dynamena pumila. We judged its reaction to warming via its pulsation activity and the growth of stolons. Pulsations of the coenosarc in colonial hydroids are a sensitive indicator of the body’s reaction to the influence of environmental factors. We tested the ability of D. pumila colonies to survive and adapt to existing at 25 °C for five days. After raising the temperature from 14 °C to 25 °C, colony growth and the pulsation of stolon growth tips on the first day increased and then decreased during the day. In the following days, the growth pulsations almost ceased, the colonies stopped growing, and their coenosarcs began to exfoliate from their perisarcs. However, by the fourth day, this process slowed down, and the colonies existed in an economy mode of experiencing unfavourable conditions. The thermal shock continued in the experiment for five days. Then, after the temperature dropped from 25 °C to 15–16 °C, all the colonies recovered within five days and continued to grow.","PeriodicalId":56070,"journal":{"name":"Ecohydrology & Hydrobiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136347784","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}

Substrate has been put forward in the literature as an important variable in determining diatom habitat preferences. This study focuses on benthic diatom assemblages and their relationship with substrate specificity in a subarctic tidal environment, which could be relevant for environmental monitoring and management. A variety of substrates were sampled and physicochemical variables measured in various areas of the Bay of Sept-Îles region (northern Gulf of Saint-Lawrence, Canada). We recorded 606 species at 14 sites from 11 substrate types to determine the associations between diatoms and their habitats. Our results suggest that the variability of assemblages in the bay is the result of a combination of the identified variables (temperature, salinity, and total dissolved solids), explaining 26.5% of the variation, and other unmeasured variables (e.g., nutrients, wave action, and currents). Substrate was not identified as a significant variable in the statistical analyses. However, some common species in the surveyed assemblages appeared to show preferences for the substrates they colonized.","PeriodicalId":56070,"journal":{"name":"Ecohydrology & Hydrobiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136022503","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}
