Background

Given the success of Volume I of this Research Topic, and how rapid the subject area is evolving, we are pleased to announce the launch of Metabolomics in Aquatic Ecology and Aquaculture - Volume II.

It has long been postulated that life on earth had its origins deep within our ancient oceans, arising from hydrothermal vent systems around 4 billion years ago. Perhaps we will never definitively know where abiogenesis took its first step in forming complex self-organising biostructures. But we do know that hidden beneath the waves of our present-day ocean are myriads of biological diversities at different levels of complexity which hold many secrets about our evolutionary history. It is estimated that of all eukaryotic species on the planet, >2 million of them are aquatic. Apart from keeping our atmosphere in check and providing various intrinsic values, our oceans, rivers, and lakes are also home to biological resources that the world relies on for sustenance and sources of income through fisheries and aquaculture. Understanding these systems and managing them sustainably is one of our greatest challenges. The rise of functional genomic tools, such as metabolomic approaches, hold great promise to answer fundamental questions around aquatic organism physiology, form, and function.

Metabolomics is an emerging frontier of systems biology in aquatic research. Although the term was coined by the ‘omics community over two decades ago, implementation of metabolomics by researchers to better understand aquatic organism physiology is still in its early stages. However, unique benefits of phenotyping organisms at a metabolic level are beginning to be recognised, particularly within applied areas research. For example, aquaculture researchers are utilising metabolomic approaches to test and formulate new functional foods that enhance animal performance, to assess and monitor the heath of aquatic stock, and to reduce negative impacts associated with intensive farming practices. Other fields such as ecotoxicology are using metabolomics to help establish or refine regulatory guidelines around aquatic contaminants of concern, and environmental scientists are embracing metabolomics to identify thresholds where metabolic reprogramming in aquatic organisms can lead to acclimation or adaptive strategies to stresses. Such applications have broad implications for food security, future visioning, and development of effective environmental policies.

Advancing knowledge in aquatic biology and ecosystem functioning through focus on metabolic phenotyping will pave the way for us to better manage our environment, understand impacts of a changing ocean, develop a successful and sustainable blue economy, and provide data to inform decision-makers and enable better protection, preservation, and conservation of our precious freshwater and marine habitats.

The goal of this Research Topic is to publish original manuscripts that highlight new developments in the broad application of metabolomic approaches towards aquatic ecology and aquaculture research.

Potential topics include, but are not limited to, metabolomics applications in:

• Evolutionary biology & systematics of aquatic organisms (e.g., chemotaxonomy)

• Aquatic ecophysiology, bioenergetics, and flux modelling

• Health of aquatic organisms (i.e., disease, immunometabolism, ecotoxicology)

• Effects of ocean acidification and marine warming on aquatic life

• Aquaculture and fisheries (e.g., nutrition, culture systems, provenance)

• Method development and validation for analysis of aquatic-derived samples

• Challenges and opportunities for aquatic-based metabolomics research

• Integrated multi-omics and bioinformatics for aquatic biology

‘Metabolomics in Aquatic Ecology and Aquaculture - Volume II’ welcomes submissions of the following article types: Original Research, Brief Research Reports, Reviews, Mini Reviews, Perspectives, Opinions, Methods, and General Commentaries. Please refer to this link for a full list of accepted article types including descriptions.

Keywords: metabolomics, multi-omics, marine biology and ecology, bioinformatics, fish and invertebrates, aquaculture

Important note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.

Frequently asked questions

  • Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

    Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

  • The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

    Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

  • As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

    A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

  • Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

  • Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

    As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

    Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

  • Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
