Special Issue Information
Dear Colleagues,
Aquatic organisms represent a critical component of global biodiversity. Thriving in highly diverse habitats—from high-altitude lakes to deep-sea trenches—they display extraordinary genetic and phenotypic diversity, offering a powerful natural laboratory for investigating adaptive evolution and speciation. Aquatic ecosystems face severe threats from overfishing, pollution, and climate change, with over 30% of species at risk of extinction. Studying their genetic diversity and adaptive mechanisms is crucial for informing targeted conservation strategies, such as designing protected areas based on genetic structure. Aquatic environments, characterized by both isolation (e.g., geographic barriers in lakes and rivers) and connectivity (e.g., ocean-current-mediated gene flow), offer an ideal system for studying diverse modes of speciation. Amid global warming-induced water temperature rise and ocean acidification, aquatic organisms' adaptive capacity is pivotal for climate resilience. Studying rapid adaptive evolution facilitates predicting species persistence and informs early warning systems in ecosystem management. Moreover, adaptations to extreme conditions—including high-altitude hypoxia and deep-sea high pressure—harbor unique genetic insights into life's responses to environmental stress. Studies in these areas not only clarify evolutionary mechanisms under "life extremes" but also provide valuable insights for biomedical research, environmental conservation, and sustainable aquatic resource utilization.
We sincerely invite global researchers to submit original research papers, reviews, perspectives, and brief reports, contributing novel insights into the genetics and evolutionary biology of aquatic organisms. Manuscripts must adhere to rigorous scientific standards, demonstrate innovation, and be supported by sufficient data and sound theoretical analysis.

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. Biology 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 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.
