Special Issue Information

Dear Colleagues,

Aquatic microbial ecology serves as a critical foundation for understanding global biogeochemical cycles, ecosystem stability, and responses to environmental change. Microorganisms, including algae, bacteria, archaea, and viruses, drive the essential functions of aquatic systems, from primary production to nutrient recycling. Advancing knowledge in this field is paramount for addressing contemporary challenges such as climate change, eutrophication, and biodiversity loss.

We are pleased to invite you to contribute to this Special Issue, “New Insights in Aquatic Microbial Ecology”. The Issue aims to compile cutting-edge research that explores the complexity, dynamics, and functions of microbial communities across diverse aquatic environments. By gathering novel findings, we seek to synthesize current understanding and highlight future directions. This focus aligns perfectly with the scope of Biology, which publishes significant advancements across the biological sciences, particularly in ecology and environmental biology.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not limited to) the following:

  • Microbial diversity, community assembly, and biogeography;
  • Functional roles and metabolic interactions within microbial consortia;
  • Impacts of climate change and anthropogenic stressors on aquatic microbiomes;
  • Microbial processes in biogeochemical cycling (e.g., carbon, nitrogen, phosphorus);
  • Advances in methodologies (e.g., omics, imaging, and bioinformatics) for microbial ecology;
  • Microbial interactions across trophic levels and food web dynamics.

We look forward to receiving your contributions.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Biology 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 2700 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.

Temporary holding water in live aquatic-product markets represents a short-term, animal-associated aquatic microenvironment, but its bacterial community dynamics remain poorly understood. In this study, 16S rRNA gene amplicon sequencing was used to characterize bacterial communities in holding water of Anguilla japonica, Sinonovacula constricta, and Ruditapes philippinarum. Samples were collected in the morning and evening to evaluate taxon-associated differences and short-term temporal shifts. The bacterial communities showed clear differentiation among the six animal–time groups. Anguilla japonica holding water showed distinct bacterial assemblages from the two bivalve-associated systems, whereas S. constricta and R. philippinarum holding water exhibited more pronounced morning-to-evening changes. In particular, R. philippinarum holding water had higher bacterial richness and a larger proportion of group-specific taxa in the morning, suggesting greater initial community heterogeneity. In addition, the occurrence–abundance analysis showed that taxa with broader distributions tended to have higher mean relative abundances, whereas Rud_8 contained a comparatively large proportion of low-occurrence taxa. Overall, this study demonstrates that live aquatic-product holding water harbors taxon-specific and time-responsive bacterial communities. These findings provide preliminary ecological insight into microbial dynamics in market-associated artificial aquatic microenvironments and highlight the need to consider aquatic animal type and sampling time in future water-quality monitoring.
