About the journal

Aims and scope

Aim

Water & Ecology (W&E) focuses on original research in the fields of water resources and science of water environments integrated with water ecology. The research areas include solutions associated with engineering, management and policies. The goal of this new journal is to address the inherent relationship and systemic changes in water systems integrated with ecological approaches and frameworks, develop theories and technologies, as well as methods for promoting knowledge, innovation and scientific breakthroughs in the field of water and ecology. W&E emphasizes outcomes with practical applications contributing to the sustainable development of society.

Scopes

Water & Ecology (W&E) publishes high-level original research beyond the traditional water and ecology science. The inclusion of technology, policy and practice through the lens of the ecology of water systems will provide unique insights and solutions.

Ecology was originally defined by Prof Ernst Haeckel in the late 1800s as the study of the relationship of organisms with their environment. In modern times this field addresses the relationships between living organisms, including humans, and their physical environment, as well as vital connections between microbiomes, plants and animals and the world around them. The ecological approach focuses on the perception and control of behaviors that occur naturally. In particular, the ecological approach focuses on aspects of all biological systems and the environment that determine the success or failure. For W&E the global challenges impacting water systems and key environs underscore the need to address not only diversity, functions and disruptions, but also the solutions to a variety of water crises.

Topics

W&E encourages research on the relationship between water and ecology, including watershed water ecosystem evolution, water ecological integrity and ecological security, climate change response and resilient water ecosystems, with new approaches such as digital/smart watersheds.

The relationship between water and ecology broadly includes water quality risk identification and assessment, early warning of water quality safety, process regulation and optimal utilization of water quality safety, environmental behavior and ecological effects of water pollutants (especially new pollutants), ecosystem response and biodiversity under the influence of water quality, as well as water ecosystem health.

The theory and method integrating water environment, water resource and water ecology. This so-called three water integration, or “one water” is defined as the integration of water environment, water resource and water ecology. This novel concept includes the ecological response to changes in water resources and the water environment, the impact of changes in aquatic ecology on the water environment's carrying capacity and the self-purification processes of water bodies, the relationship and regulation between water resources, the water environment, and aquatic ecology, the micro and macro mechanisms and implementation paths for the integration of Three-Water, the coupling relationship of water energy, the social, economic, and industrial association mechanisms of the integration of Three-Water, as well as the construction of green river basins, etc.

Basin water ecosystem evolution, including the spatiotemporal evolution of aquatic ecosystems at different scales, the interactive effects between terrestrial and marine waters and ecology, the evolution and ecological restoration of coastal habitats, as well as the assessment and construction of green river basins.

Water ecological integrity and ecological security, including the assessment of aquatic ecological integrity and the identification of influencing factors, the impact of water resources, water environment, and water quality on the integrity of aquatic ecosystems, the restoration and maintenance of aquatic ecological integrity, the biological and ecological safety of water, and the ecological benefits of the diversified recycling use of water resources.

Climate change response and resilience of water ecosystems, including the impact of climate change on water quality and water ecology, water environmental problems caused by extreme climate, the impact of climate issues on biodiversity in water ecosystems, and the health management of water ecosystems in response to climate issues.

Digital/smart watershed, including intelligent perception and monitoring of water quality, big data analysis of water resources, water environment and water quality, as well as the precise management and regulation of aquatic ecosystems based on machine learning.

Peer review

This journal follows a single anonymized review process. Your submission will initially be assessed by our editors to determine suitability for publication in this journal. If your submission is deemed suitable, it will typically be sent to a minimum of two reviewers for an independent expert assessment of the scientific quality. The decision as to whether your article is accepted or rejected will be taken by our editors. This decision is final.

Our editors are not involved in making decisions about papers which:

• they have written themselves.

• have been written by family members or colleagues.

• relate to products or services in which they have an interest.

Any such submissions will be subject to the journal's usual procedures and peer review will be handled independently of the editor involved and their research group.

1. All manuscripts are reviewed by the editorial office. Any papers which fail to meet the basic standards of the journal will be desk-rejected for reasons like out of scope, ethical conflicts, high similarities, lack of originality, flaws in research design or methods, etc. The editorial office will reassign selected papers to the Editor-in-chief.  

2. The Editor-in-chief will invite multiple reviewers to review the paper or assign an editorial board member to invite reviewers to review this paper.

3. After at least two reviewers give their reviews and comments, the Editor-in-chief (or the assigned Editor) provides feedback to the authors, based on reviewer comments and his own review comments.

4. When the author submits the revised manuscript, the assigned editor and Editor-in-chief will collaborate to make a final decision.

5. For submissions from the Editor-in-Chief, Associate Editors, Guest Editor(s), other journal Board members, and authors who have conflicts of interest with them, we ensure that the paper is handled confidentially by a different team member.

6. For submissions to Special Issues; if there are conflicts of interest between the Guest Editor(s) and authors, the submissions will be handled by another Editor from the Editorial Board who will manage the peer review process and make the decision whether to accept or reject the paper after peer review.

Declaration of generative AI in scientific writing

Authors can declare the use of generative AI in scientific writing upon submission of the paper. The following guidance refers only to the writing process, and not to the use of AI tools to analyse and draw insights from data as part of the research process:

Generative AI and AI-assisted technologies should only be used in the writing process to improve the readability and language of the manuscript.

The technology must be applied with human oversight and control and authors should carefully review and edit the result, as AI can generate authoritative-sounding output that can be incorrect, incomplete or biased. Authors are ultimately responsible and accountable for the contents of the work.

Authors must not list or cite AI and AI-assisted technologies as an author or co-author on the manuscript since authorship implies responsibilities and tasks that can only be attributed to and performed by humans.

The use of generative AI and AI-assisted technologies in scientific writing can be declared by adding a statement at the end of the manuscript when the paper is first submitted. The statement will appear in the published work and should be placed in a new section before the references list. An example:

Title of new section: Declaration of generative AI and AI-assisted technologies in the writing process.

Statement: During the preparation of this work the author(s) used [NAME TOOL / SERVICE] in order to [REASON]. After using this tool/service, the author(s) reviewed and edited the content as needed and take(s) full responsibility for the content of the published article.

The declaration does not apply to the use of basic tools, such as tools used to check grammar, spelling and references. If you have nothing to disclose, you do not need to add a statement.

We advise you to read our policy for authors on the use of generative AI and AI-assisted technologies for Elsevier.

Please note: to protect authors’ rights and the confidentiality of their research, this journal does not currently allow the use of Generative AI or AI-assisted technologies such as ChatGPT or similar services by reviewers or editors in the peer review and manuscript evaluation process. We are actively evaluating compliant AI tools and may revise this policy in the future.

Preprint sharing

Authors may share preprints in line with Elsevier's article sharing policy. Sharing preprints, such as on a preprint server, will not count as prior publication.

We advise you to read our policy on multiple, redundant or concurrent publication.

Image manipulation

We accept that authors sometimes need to adjust images for clarity but any manipulation of images for the purpose of deception or fraud will be seen as scientific ethical abuse and will be dealt with accordingly.

Authors must adhere to this journal’s policy for graphical images:

• No specific feature within an image may be enhanced, obscured, moved, removed or introduced.

• Adjustments of brightness, contrast, or color balance are acceptable if, and only as long as, they do not obscure or eliminate any information present in the original image.

• Nonlinear adjustments such as changes to gamma settings must be disclosed in the figure legend.

• We do not permit the use of generative AI or AI-assisted tools to create or alter images in submitted manuscripts. Please read our policy on the use of generative AI and AI-assisted tools in figures, images and artwork, which can be found in Elsevier’s GenAI Policies for Journals.

To verify compliance with the above, this journal may send your images to a third-party service who screen for image irregularities. Our editors may ask you to provide original data or images if any questions arise as a result of the screening. The final decision as to whether images are acceptable will be taken by our editors.

Authors are encouraged to carefully check all images before submission and to connect all the data in any figures to the original, unprocessed data.

Studies in humans and animals

Authors must follow ethical guidelines for studies carried out in humans and animals.

Studies in humans

Work which involves the use of human subjects should be carried out in accordance with the World Medical Association Declaration of Helsinki: Ethical principles for medical research involving human subjects.

Manuscripts should follow the International Committee of Medical Journal Editors (ICMJE) recommendations for the conduct, reporting, editing and publication of scholarly work in medical journals and aim to be representative of human populations in terms of sex, age and ethnicity. Sex and gender terms should be used correctly, as outlined by WHO (World Health Organization).

Manuscripts must include a statement that all procedures were performed in compliance with relevant laws and institutional guidelines and have been approved by the appropriate institutional committee(s). The statement should contain the date and reference number of the ethical approval(s) obtained.

Manuscripts must also include a statement that informed consent was obtained for experimentation with human subjects.

Studies in animals

All animal experiments should comply with ARRIVE (Animal Research: Reporting of In Vivo Experiments) guidelines.

Studies should be carried out in accordance with Guidance on the operation of the Animals (Scientific Procedures) Act 1986 and associated guidelines, EU Directive 2010/63 for the protection of animals used for scientific purposes or the NIH (National Research Council) Guide for the Care and Use of Laboratory Animals (PDF).

The sex of animals, and where appropriate, the influence (or association) of sex on the results of the study must be indicated and a statement included in your manuscript that such guidelines as listed above have been followed.

Informed consent and patient details

Authors must document in the manuscript that ethics committee approval and informed consent have been obtained for studies involving patients or volunteers (including organ/tissue donors). Key guidelines:

• Appropriate consents, permissions and releases must be obtained if case details, personal information and images of patients or any other individuals are included in a publication, even if anonymized.

• Patient and research subjects’ names, initials, hospital or social security numbers, dates of birth or any other personal or identifying information should never be used, even where consent has been provided.

Written consents must be retained. They should not be provided to this journal unless this is specifically requested in exceptional circumstances, for example, when a legal issue arises. Only then should you provide copies of the consents, or evidence that all relevant consents were obtained.  

Personal details of any patient must only be included in your article or in any supplementary materials (including all images and videos) in cases where written permission has been given by the patient (or, where applicable, the next of kin).

We advise you to review Elsevier’s policy on patient consent prior to preparing your manuscript.

Registration of clinical trials

Clinical trials must be registered in a public trials registry in accordance with International Committee of Medical Journal Editors (ICMJE) clinical trials guidelines and as a condition of publication in this journal. Purely observational studies, in which the assignment of the medical intervention is not at the discretion of the investigator, do not require registration. 

Some key excerpts from the guidelines include: 

• Trials must be registered at or before the onset of patient enrolment.  

• The clinical trial registration number should be included at the end of the article abstract.  

• A clinical trial is defined as any research study that prospectively assigns human participants, or groups of humans, to one or more health-related interventions to evaluate the effects of health outcomes.  

• Health-related interventions include any intervention used to modify a biomedical or health-related outcome such as drugs, surgical procedures, devices, behavioural treatments, dietary interventions, and process-of-care changes.  

• Health outcomes include any biomedical or health-related measures obtained in patients or participants, including pharmacokinetic measures and adverse events.  

Reporting on clinical trials

We recommend that authors follow CONSORT guidelines when presenting randomized controlled trials.  

Authors must provide the CONSORT checklist at manuscript submission with an accompanying flow diagram illustrating the progress of patients through the trial, including recruitment, enrolment, randomization, withdrawal, completion and a description of the randomization procedure.

The equator network has guidelines covering CONSORT: 

• Read the CONSORT guidelines. 

• Follow the CONSORT checklist. 

Clinical trial results

Authors must disclose all posting in registries of results of the same or closely related work.  

We follow the International Committee of Medical Journal Editors (ICMJE) clinical trials guidelines. Editors will not consider results to be a prior publication if they have already been posted in the same clinical trials registry in which primary registration resides, as long as the results are presented in the form of a brief structured abstract (fewer than 500 words) or table.  

Disclosing results in other circumstances, such as in an investors’ meeting, for example, is discouraged and may jeopardise consideration of your manuscript by this journal.

Writing and formatting

File format

We ask you to provide editable source files for your entire submission (including figures, tables and text graphics). Some guidelines:

• Save files in an editable format, using the extension .doc/.docx for Word files and .tex for LaTeX files. A PDF is not an acceptable source file.

• Lay out text in a single-column format.

• Use spell-check and grammar-check functions to avoid errors.

We advise you to read our Step-by-step guide to publishing with Elsevier.

We are committed to supporting the storage of, access to and discovery of research data, and our research data policy sets out the principles guiding how we work with the research community to support a more efficient and transparent research process.

Research data refers to the results of observations or experimentation that validate research findings, which may also include software, code, models, algorithms, protocols, methods and other useful materials related to the project.

Please read our guidelines on sharing research data for more information on depositing, sharing and using research data and other relevant research materials.

For this journal, the following instructions from our research data guidelines apply.

Option A: Research data deposit and citation

You are encouraged to:

• Deposit your research data in a relevant data repository.

• Cite this dataset in your article.

Data statement

To foster transparency, you are to state the availability of any data at submission.

Ensuring data is available may be a requirement of your funding body or institution. If your data is unavailable to access or unsuitable to post, you can state the reason why (e.g., your research data includes sensitive or confidential information such as patient data) during the submission process. This statement will appear with your published article on ScienceDirect.

Read more about the importance and benefits of providing a data statement.

Data linking

Linking to the data underlying your work increases your exposure and may lead to new collaborations. It also provides readers with a better understanding of the described research.

If your research data has been made available in a data repository there are a number of ways your article can be linked directly to the dataset:

• Provide a link to your dataset when prompted during the online submission process.

• For some data repositories, a repository banner will automatically appear next to your published article on ScienceDirect.

• You can also link relevant data or entities within the text of your article through the use of identifiers. Use the following format: Database: 12345 (e.g. TAIR: AT1G01020; CCDC: 734053; PDB: 1XFN).

Learn more about linking research data and research articles in ScienceDirect.

Mendeley data

This journal supports Mendeley Data, enabling you to deposit any research data (including raw and processed data, video, code, software, algorithms, protocols and methods) associated with your manuscript in a free-to-use, open access repository.

Before or during the submission process, you can deposit the relevant datasets to Mendeley Data. Please include the DOI of the deposited dataset(s) in your main manuscript file.

The datasets will be listed and directly accessible to readers next to your published article online.

Learn more about Mendeley Data for journals.

Article structure

Article sections

• Divide your article into clearly defined and numbered sections. Number subsections 1.1 (then 1.1.1, 1.1.2, ...), then 1.2, etc.  

• Use the numbering format when cross-referencing within your article. Do not just refer to "the text."  

• You may give subsections a brief heading. Headings should appear on a separate line. 

• Do not include the article abstract within section numbering.  

Glossary

Please provide definitions of field-specific terms used in your article, in a separate list.

Acknowledgements

Include any individuals who provided you with help during your research, such as help with language, writing or proof reading, in the acknowledgements section. Acknowledgements should be placed in a separate section which appears directly before the reference list. Do not include acknowledgements on your title page, as a footnote to your title, or anywhere else in your article other than in the separate acknowledgements section.

Author contributions: CRediT

Corresponding authors are encouraged to acknowledge co-author contributions using CRediT (Contributor Roles Taxonomy) roles:

• Conceptualization

• Data curation

• Formal analysis

• Funding acquisition

• Investigation

• Methodology

• Project administration

• Resources

• Software

• Supervision

• Validation

• Visualization

• Writing – original draft

• Writing – review and editing

Not all CRediT roles will apply to every manuscript and some authors may contribute through multiple roles.

We advise you to read more about CRediT and view an example of a CRediT author statement.

Funding sources

Authors must disclose any funding sources who provided financial support for the conduct of the research and/or preparation of the article. The role of sponsors, if any, should be declared in relation to the study design, collection, analysis and interpretation of data, writing of the report and decision to submit the article for publication. If funding sources had no such involvement this should be stated in your submission.

List funding sources in this standard way to facilitate compliance to funder's requirements:

Funding: This work was supported by the National Institutes of Health [grant numbers xxxx, yyyy]; the Bill & Melinda Gates Foundation, Seattle, WA [grant number zzzz]; and the United States Institutes of Peace [grant number aaaa].

It is not necessary to include detailed descriptions on the program or type of grants, scholarships and awards. When funding is from a block grant or other resources available to a university, college, or other research institution, submit the name of the institute or organization that provided the funding.

If no funding has been provided for the research, it is recommended to include the following sentence:

This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.

Appendices

We ask you to use the following format for appendices:

• Identify individual appendices within your article using the format: A, B, etc.

• Give separate numbering to formulae and equations within appendices using formats such as Eq. (A.1), Eq. (A.2), etc. and in subsequent appendices, Eq. (B.1), Eq. (B. 2) etc. In a similar way, give separate numbering to tables and figures using formats such as Table A.1; Fig. A.1, etc.

References

References within text

Any references cited within your article should also be present in your reference list and vice versa. Some guidelines:

• References cited in your abstract must be given in full.

• We recommend that you do not include unpublished results and personal communications in your reference list, though you may mention them in the text of your article.

• Any unpublished results and personal communications included in your reference list must follow the standard reference style of the journal. In substitution of the publication date add "unpublished results" or "personal communication."

• References cited as "in press" imply that the item has been accepted for publication.

Linking to cited sources will increase the discoverability of your research.

Before submission, check that all data provided in your reference list are correct, including any references which have been copied. Providing correct reference data allows us to link to abstracting and indexing services such as Scopus, Crossref and PubMed. Any incorrect surnames, journal or book titles, publication years or pagination within your references may prevent link creation.

We encourage the use of Digital Object Identifiers (DOIs) as reference links as they provide a permanent link to the electronic article referenced.

Reference style

Indicate references by adding a number within square brackets in the text. You can refer to author names within your text, but you must always give the reference number, e.g., "as demonstrated [3,6]. Barnaby and Jones [8] obtained a different result ....".

Number references in the order they appear in your article.   

Abbreviate journal names according to the List of Title Word Abbreviations (LTWA).

Web references

When listing web references, as a minimum you should provide the full URL and the date when the reference was last accessed. Additional information (e.g. DOI, author names, dates or reference to a source publication) should also be provided, if known.

You can list web references separately under a new heading directly after your reference list or include them in your reference list.

Data references

We encourage you to cite underlying or relevant datasets within article text and to list data references in the reference list.

When citing data references, you should include:

• author name(s)

• dataset title

• data repository

• version (where available)

• year

• global persistent identifier

Add [dataset] immediately before your reference. This will help us to properly identify the dataset. The [dataset] identifier will not appear in your published article.

Preprint references

We ask you to mark preprints clearly. You should include the word "preprint" or the name of the preprint server as part of your reference and provide the preprint DOI.

Where a preprint has subsequently become available as a peer-reviewed publication, use the formal publication as your reference.

If there are preprints that are central to your work or that cover crucial developments in the topic, but they are not yet formally published, you may reference the preprint.

Reference management software

Most Elsevier journals have their reference template available in popular reference management software products. These include products that support Citation Style Language (CSL) such as Mendeley Reference Manager.

If you use a citation plug-in from these products, select the relevant journal template and all your citations and bibliographies will automatically be formatted in the journal style. We advise you to remove all field codes before submitting your manuscript to any reference management software product.

If a template is not available for this journal, follow the format given in examples in the reference style section of this Guide for Authors.
