Special Issue Information

Dear Colleagues,

Freshwater biodiversity plays a crucial role in maintaining ecosystem health, regulating biogeochemical cycles, and supporting essential ecosystem services. However, aquatic habitats are increasingly threatened by a range of anthropogenic pressures, including habitat degradation, hydrological alteration, pollution, overexploitation, and the spread of invasive species. Global environmental changes such as climate warming, shifting precipitation patterns, and extreme hydrological events further accelerate biodiversity loss and impair ecosystem stability and function. This Special Issue aims to advance our understanding of how environmental gradients and human activities interact to shape freshwater biodiversity, ecosystem functioning, and water quality. We invite original research articles, reviews, and case studies addressing ecological and hydromorphological dimensions of freshwater degradation, as well as innovative strategies for the conservation, restoration, and sustainable management of aquatic ecosystems under increasing environmental stress.

Dr. Renata Kędzior

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.

Riverine bacteria are vital to geochemical cycling, climate change, and water environments, and the relative research requires knowledge from multiple disciplines, including microbiology, ecology and river dynamics. The influence of river dynamics and morphology on riverine bacteria is drawing increasing attention; yet, there are few comprehensive reviews on the riverine bacteria from the perspective of river dynamics. Therefore, this paper systematically reviews the research progress from the perspective of river dynamics, focusing on the research techniques and methods of riverine bacteria, the impact of hydrodynamic conditions, the ecological effects of dam construction, and the spatial distribution pattern of river bacteria. The review indicates that hydrodynamic processes and human activities such as dam construction drive community reorganization of planktonic and sedimentary bacteria across scales from microhabitats to macrolandscapes by altering aquatic environments, promoting microbial interactions, and affecting diversity, thereby shaping their complex spatiotemporal distribution patterns. Finally, this paper looks forward to future research directions, emphasizing the need to further reveal the diversity of planktonic and sedimentary bacteria, their genetic functions and community construction mechanisms, and to deeply analyze the feedback driving relationship between hydrodynamics, river morphology and riverine bacteria.
