Special Issue Information

Dear Colleagues,

Every day, industries, agriculture, and the general population are using water and releasing many compounds in wastewater. Indeed, agriculture practices, industrial discharges, and human activities play an important role in the release of pollutants in wastewater. All these practices have generated various pollutants and altered the water cycle, thereby causing global concern due to their impact on wildlife. Nowadays, more than 700 emerging pollutants, their metabolites, and transformation products have been identified. The prominent classes are as follows: pharmaceuticals (urban, stock farming), pesticides (agriculture), disinfection by-products (urban, industry), wood preservation, and industrial chemicals (industry). Emerging pollutants are defined as synthetic or naturally occurring chemicals that are not commonly observed in the environment but which can enter the environment and cause known or suspected adverse ecological effects. In some cases, it is likely that the release of emerging pollutants into the environment has occurred over a long time, but this may not have been recognized until new detection methods were developed. Because of the potential impact of these substances on aquatic life and ecosystems, the lack of knowledge regarding their effects on the environment, and the deficiency in analytical and sampling techniques, action is urgently required at multiple levels. The problem of emerging pollutants lies in not knowing the impact of their middle- or long-term effects on the environment and aquatic environments.

This Special Issue welcomes original research articles or reviews on all aspects of emerging pollutants, with an emphasis on the links between different ecological groups. Biogeochemical and ecological processes, as well as the flow of energy and matter through water ecosystems, are also within the scope of this issue. We are especially interested in manuscripts that concentrate on the effect of emerging pollutants on aquatic health and ecological communities, with a focus on biodiversity. We also welcome work that suggests ways to mitigate environmental impacts through management and the improvement of the quality of the environment.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Diversity is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Protists inhabit marine, brackish and fresh waters. The salt barrier plays an important role in the origin of their diversity. Salinity tolerance differs among species and sometimes even among different strains of the same species, indicating local adaptation. Dinoflagellates from the Apocalathium genus are represented by at least four species, which originated via rapid and recent radiation. Water salinity was suggested as one of the key factors for this radiation. A previous study found RNA transcripts, which belong exclusively to saline strains of Apocalathium, and were absent in its freshwater strains. In the present paper, the diversity of these transcripts and their orthologs from marine and freshwater protists were analysed using bioinformatic approaches. First, it was found that these specific transcripts translated to the proteins, which are important for osmoregulation (e.g., transport of various compounds including glycine betaine, regulation of microtubule organisation, post transcriptional modifications). This supports the idea that speciation within Apocalathium resulted in the loss of osmoregulatory genes by freshwater species. Second, protein distribution was not highly species specific, because their orthologs were found in different dinoflagellates and were relatively common in other phototrophic protists, though the sequences were highly variable. Proteins from 13 orthogroups were absent or very rare in studied freshwater genomes and transcriptomes. They could play a specific role in protists salinity tolerance. Third, detailed phylogenetic analyses of betaine-like transporter and chloride transmembrane transporters, which probably are one of the key proteins associated with salinity tolerance, revealed high levels of multiple and variable copies that were not eliminated from the genome during the evolution. The expression of their genes could be important in the adaptation of dinoflagellates to salinity changes, as it was already shown for some other protists. Full article
