Preparing your materials

Policy on prior publication

When authors submit manuscripts to this journal, these manuscripts should not be under consideration, accepted for publication or in press within a different journal, book or similar entity, unless explicit permission or agreement has been sought from all entities involved. However, deposition of a preprint on the author’s personal website, in an institutional repository, or in a preprint archive shall not be viewed as prior or duplicate publication. Authors should follow the Cambridge University Press Preprint Policy regarding preprint archives and maintaining the version of record. 

English language editing services 

Authors, particularly those whose first language is not English, may wish to have their English-language manuscripts checked by a native speaker before submission. This step is optional, but may help to ensure that the academic content of the paper is fully understood by the Editor and any reviewers.  

In order to help prospective authors to prepare for submission and to reach their publication goals, Cambridge University Press offers a range of high-quality manuscript preparation services – including language editing – delivered in partnership with American Journal Experts. You can find out more on our Language Services page.

Please note that the use of any of these services is voluntary, and at the author's own expense. Use of these services does not guarantee that the manuscript will be accepted for publication, nor does it restrict the author to submitting to a Cambridge-published journal. 

Authorship and contributorship

All authors listed on any papers submitted to this journal must be in agreement that the authors listed would all be considered authors according to disciplinary norms, and that no authors who would reasonably be considered an author have been excluded. For further details on this journal’s authorship policy, please see this journal's publishing ethics policies.

Author affiliations

Author affiliations should represent the institution(s) at which the research presented was conducted and/or supported and/or approved. For non-research content, any affiliations should represent the institution(s) with which each author is currently affiliated. 

For more information, please see our author affiliation policy and author affiliation FAQs.

ORCID

We require all corresponding authors to identify themselves using ORCID when submitting a manuscript to this journal. ORCID provides a unique identifier for researchers and, through integration with key research workflows such as manuscript submission and grant applications, provides the following benefits:

  • Discoverability: ORCID increases the discoverability of your publications, by enabling smarter publisher systems and by helping readers to reliably find work that you have authored.
  • Convenience: As more organisations use ORCID, providing your iD or using it to register for services will automatically link activities to your ORCID record, and will enable you to share this information with other systems and platforms you use, saving you re-keying information multiple times.
  • Keeping track: Your ORCID record is a neat place to store and (if you choose) share validated information about your research activities and affiliations.

See our ORCID FAQs for more information.

If you don’t already have an iD, you will need to create one if you decide to submit a manuscript to this journal. You can register for one directly from your user account on ScholarOne, or alternatively via https://ORCID.org/register.

If you already have an iD, please use this when submitting your manuscript, either by linking it to your ScholarOne account, or by supplying it during submission using the "Associate your existing ORCID iD" button.

ORCIDs can also be used if authors wish to communicate to readers up-to-date information about how they wish to be addressed or referred to (for example, they wish to include pronouns, additional titles, honorifics, name variations, etc.) alongside their published articles. We encourage authors to make use of the ORCID profile’s “Published Name” field for this purpose. This is entirely optional for authors who wish to communicate such information in connection with their article. Please note that this method is not currently recommended for author name changes: see Cambridge’s author name change policy if you want to change your name on an already published article. See our ORCID FAQs for more information. 

Competing Interests

All authors must include a competing interest declaration in their main manuscript file. This declaration will be subject to editorial review and may be published in the article. 

Competing interests are situations that could be perceived to exert an undue influence on the content or publication of an author’s work. They may include, but are not limited to, financial, professional, contractual or personal relationships or situations. 

If the manuscript has multiple authors, the author submitting must include competing interest declarations relevant to all contributing authors. 

Example wording for a declaration is as follows: “Competing interests: Author 1 is employed at organisation A, Author 2 is on the Board of company B and is a member of organisation C. Author 3 has received grants from company D.” If no competing interests exist, the declaration should state “Competing interests: The author(s) declare none”. 

Supplementary materials

Material that is not essential to understanding or supporting a manuscript, but which may nonetheless be relevant or interesting to readers, may be submitted as supplementary material. Supplementary material will be published online alongside your article, but will not be published in the pages of the journal. Types of supplementary material may include, but are not limited to, appendices, additional tables or figures, datasets, videos, and sound files.

Supplementary materials will not be typeset or copyedited, so should be supplied exactly as they are to appear online. Please see our general guidance on supplementary materials for further information.

Where relevant we encourage authors to publish additional qualitative or quantitative research outputs in an appropriate repository, and cite these in manuscripts.

Author Hub

You can find guides for many aspects of publishing with Cambridge at Author Hub, our suite of resources for Cambridge authors.

Preparing your manuscript for submission
Manuscript format

Manuscripts should be submitted as line-numbered Microsoft Word files, and include the following sections:

Title page

  • Article title: should be no more than 20 words with no authorities associated with the species
  • Running head: a shortened version of the title (not more than 43 characters) should be suggested
  • Author names
  • Author affiliations: please provide an affiliation for each author that includes department, institution, city and country, and identify each author’s affiliation by a superscript number. Author affiliations should represent the institution(s) at which the research presented was conducted and/or supported and/or approved. For non-research content, any affiliations should represent the institution(s) with which each author is currently affiliated. For more information, please see our author affiliation policy and author affiliation FAQs.

Main text

The main text should include the following sections: Introduction; Materials and Methods; Results; Discussion.

Data

Manuscripts with a Data Availability Statement should include it here.

Acknowledgements

You may acknowledge individuals or organizations that provided advice and/or support (non-financial). Formal financial support and funding should be listed in the following section.

Author contributions

Please provide a very brief description of the contribution of each author to the research. Their roles in formulating the research question(s), designing the study, carrying out the study, analysing the data, interpreting the findings and writing the article should be stated for each author.

Financial support

Please provide details of the sources of financial support of all authors, including grant numbers. For example, ‘This work was supported by the Medical Research Council (grant number XXXXXXX)’. Multiple grant numbers should be separated by a comma and space, and where research was funded by more than one agency, the different agencies should be separated by a semi-colon, with ‘and’ before the final funder. Grants held by different authors should be identified as belonging to individual authors by the authors’ initials. For example, ‘This work was supported by the Wellcome Trust (A.B., grant numbers XXXX, yyyy), (C.D., grant number ZZZZ); the Natural Environment Research Council (E.F., grant number FFFF); and the National Institutes of Health (A.B., grant number GGGG), (E.F., grant number HHHH)’. Where no specific funding has been provided for research, please provide the following statement: ‘This research received no specific grant from any funding agency, commercial or not-for- profit sectors’.

Conflict of interest

Please provide details of all known financial, professional and personal relationships with the potential to bias the work. Where no known conflicts of interest exist, please include the following statement: "The author (s) declare none."

For more information on what constitutes a conflict of interest, please see our Research Publishing Ethics Guidelines.

Ethical standards

Research involving vertebrates and regulated invertebrates should comply with relevant national and international animal welfare guidelines and where possible, be approved by an ethics committee. The name of the ethics committee and the ethics committee approval number should be included here, along with the national and international guidelines that were followed. Research reporting animal research should follow the ARRIVE reporting guidelines

References

References and citations should be formatted correctly in journal style when the article is submitted to the journal but formatting is not grounds for rejection at the submitting phase.

References in the text should refer to the author’s name (no initials) and year of publication. Two authors should be cited using ‘&’ (Rainbow & Dellinger, 1993); for more than two authors, the name of the first author followed by ‘et al.’ (Lallier et al., 1987). Where an article is published but yet to be allocated to an Issue, the citation should take the form (Relles et al., published online 24 August 2018). Online resources should be cited following the convention (Continuous Plankton Recorder Survey, accessed online 23 September 2018). When citing more than one publication use date order and a semi-colon as a separator, e.g. (Mykels & Skinner, 1985a, b; Skinner, 1996; Gorind et al., 1997).

All literature quoted in the text must be listed in alphabetical and chronological order of author names at the end of each manuscript, following the Cambridge A style. When more than one publication with the same first author is cited the following order alphabetically applies: (a) single author, according to publication dates; (b) same author and one co-author; (c) same author and more than one co-author.

The manuscript should be carefully checked to ensure the details of authors and dates cited in the text exactly match those in the reference list. Cross checking of references in the text to the cited literature and vice versa is the responsibility of the author.

The style follows the full name according to the ‘World List of Scientific Periodicals’ latest edition, London. Titles of journals must be written in FULL (not abbreviated) and references to books should include the place of publication and the publisher.

Figures

Figures should be referred to in numerical order and in full in the body of the text (e.g. Figure 1). If figures are in parts, please label with upper case letters (A, B, C etc.) in the top left corner of each part. Figure legends should be placed in the main manuscript file following the references, and take the following style:

Fig. 1. Ceratothoa collaris Schioedte & Meinert, 1883, adult female: (A) pereopod 1; (B) pereopod 7; (C–G) pleopods 1–5 ventral view; (H) uropods. Scale bars: A–G, 2 mm; H, 3 mm.

Please note that all figures must be supplied as separate files; figures supplied as embedded objects in Microsoft Word cannot be accepted. Please consult the journal artwork guide for a detailed specification on accepted file formats.

Authors must obtain permission from the original publisher if they intend to use figures from other sources, and due acknowledgement should be made in the legend as follows: Permission to replicate this figure has been given to the authors by XXX. For detailed instructions on securing permissions, please see here.

From 2022, JMBA will be published online only and so there will be no charges for colour images.

The JMBA uses a different colour image for the cover of each new Issue. If you exclusively hold copyright in a high-quality image either used within your accepted article, or directly related to it, that you believe might make a suitable cover image, please highlight on article submission. The Journal will then contact you should it wish to discuss further.

Tables

Tables should be placed in the main manuscript file at the end of the document, not within the main text. The journal cannot accept text formatted with tab characters or images of tables embedded in word files.

Authors must obtain permission from the original publisher if they intend to use tables from other sources, and due acknowledgement should be made in the legend as follows: Permission to replicate this table has been given to the authors by XXX. For detailed instructions on securing permissions, please see here.

Supplementary material

Online publishing gives authors the opportunity to include data that would be impossible or impractical to include in the printed version. These data might substantially enhance the importance of the research and might also be of benefit to readers.

Authors may include tables and figures as well as data such as videos, 3-D structures/images, extensive datasets and any other supplementary material not suitable for print duplication. All supplementary material must be submitted with the original manuscript and cited in a relevant place in the text of the paper. Supplementary data should be referred to in the text with the prefix "S" (e.g. Supplementary Table S1, Supplementary Figure S1).

Supplementary files will be peer reviewed but not copy-edited or typeset, and will be published as supplied.
