Special Issue Information

Dear Colleagues,

We are pleased to announce the call for papers for a Special Issue dedicated to diatom biodiversity and their adaptive responses to environmental change. The issue, titled “Diatom Biodiversity and Their Adaptation to Environment Change,” aims to gather the latest research on the ecology, biogeography, and responses of diatoms to the dynamic transformations occurring in aquatic habitats.

Diatoms (Bacillariophyta) are a highly diverse group of unicellular algae that play a fundamental role in aquatic ecosystems. Due to their sensitivity to environmental changes and high species richness, they are widely used in biomonitoring, including assessments of water quality and the effects of climate change and anthropogenic pressure.

We warmly welcome submissions focusing on diatoms inhabiting a wide range of aquatic environments — from springs, streams, and rivers to lakes, wetlands, seas, and oceans. We are interested in floristic and taxonomic studies as well as research on community structure, ecological interactions, succession processes, and responses to anthropogenic factors.

Particularly valuable will be contributions addressing the impact of climate change, habitat alteration, and pollution on the diversity and condition of diatoms, as well as on the functioning of entire microalgal communities. We encourage interdisciplinary approaches that integrate ecology, hydrobiology, geochemistry, paleoecology, and modern molecular methods.

We hope this Special Issue will serve as a platform for knowledge exchange among researchers working in various aquatic systems and will contribute to a deeper understanding of diatoms as bioindicators and key components of ecosystem processes in the face of global environmental change.

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 250 words) can be sent to the Editorial Office for assessment.

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. Water is an international peer-reviewed open access semimonthly 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 2600 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.
  • Reprint: MDPI Books provides the opportunity to republish successful Special Issues in book format, both online and in print.

Using a coordinated multi-year monitoring dataset collected during the 2020–2024 partial-opening management period, we examined benthic diatom assemblages across the Sejong, Gongju, and Baekje weirs in the Geum River, Republic of Korea. Seasonal surveys at eight stations were used to evaluate spatiotemporal variation in water quality and benthic diatom community structure under this hydrological management regime. Annual basin-wide averages showed gradual interannual changes in water quality, including declines in total phosphorus, total nitrogen, chlorophyll-a, turbidity, and biochemical oxygen demand after 2021, accompanied by increased dissolved oxygen. Diatom community indices based on relative-abundance data showed corresponding temporal variation, with decreased dominance and increased Shannon diversity, evenness, and taxon richness. Ordination analyses indicated gradual differentiation between the earlier (2020–2021) and later (2022–2024) monitoring groups within the study period, whereas random forest models showed limited explanatory power and were treated as exploratory. Overall, the results support benthic diatoms as sensitive descriptors of ecological change in flow-regulated monsoonal rivers while underscoring the value of long-term monitoring where true pre-intervention biological baselines are unavailable.
