Author Guidelines

Initial Submission

Manuscripts must be original work and can only be submitted by registering to the journal’s online system. All manuscripts must be in English, preferably checked by a native English-speaking colleague, before submission. The latter will greatly improve both the legibility and scientific quality of your paper for acceptance by the journal if English is not your first language. Submissions requiring significant editing for language and grammar may be rejected by the Handling Editor immediately.

If this manuscript has previously been submitted to any publication outlet and has been rejected, this must be disclosed and a rationale for its submission to MMS should be provided as a supplementary file to the main submission. In that case, we strongly encourage authors to submit, together with the manuscript, the comments made by the referees and editor of that other journal together with details about how these comments were taken into account in the new submission.

Authors are asked to provide a list of 4 potential reviewers (full name, expertise and contact details).

Authors may contribute with submissions to one of the following sections of the journal:

  • Research articles (normally comprised within 15 printed pages, i.e. approximately 9,000 words);
  • Short communications, brief research notes on important new information (up to 4 printed pages with no more than 2 Tables/Figures);
  • Reviews, state-of-the-art critical evaluations of important current research areas (up to 30 pages; for longer manuscripts prior agreement with the Editor-in-Chief is needed);
  • Comments, critical, fair assessments of published articles and Reply Comments, replies to comments (normally up to 3 printed pages)
  • Theme Sections, integrated multi-author analyses and syntheses initiated and coordinated by acknowledged experts; led by one or more of the MMS Editorial Staff, sometimes including Guest Editors; suggestions for Theme Sections are welcomed (please contact the Editor-in-Chief).  'Special issues covering Congresses' will be accepted only if the publication cost is fully covered by the congress organizers. They will appear in Supplement issues.
  • Collective articles: These new series refer to contributions from a maximum of Two authors. All contributors shall be considered co-authors of such collective articles. The authors responsible for each record are listed at the beginning of each section. Relevant reports should be submitted as sections (normally no more than one printed page) of a collective article and not as separate research articles or short communications.The authors should structure their text (restricted to 400 words), without headings. References: 4-5 key references, following the format of the journal; Figures: a maximum of two (tables are also considered as figures). Lengthy tables can be added, in the form of on-line supplementary material.

Series A. 'New Mediterranean Biodiversity Records (June/December 201x)': This series will included new records of marine species found in the Mediterranean and/or information on the spatial distribution of already established species of particular interest (first record in a country or in a new MSFD area) . Photos of the species and co-ordinates of the sites they were found, are necessary.

Manuscript format

Manuscripts should be submitted as a single file (MS Word not exceeding 5 Mb in size), with figures, tables and appendices embedded in the manuscript after the list of references. All files uploaded to the system should contain in their name the author’s last name and the type of file uploaded. For example: Zenetos_Research Article.doc or Zenetos_Data.doc or Zenetos_Image_1.jpg


The main text should be structured in the following sequence: Title, Authors, Abstract, Keywords,  Introduction, Materials and Methods, Results, Discussion, Acknowledgements, References, Appendix, Figures, and Tables. First order section headings (Introduction, Methods, Results, Discussion etc) should be in bold, second order headings should be italicized. Please avoid verbosity and any unnecessary details. The corresponding author should be identified with an asterisk and footnote.

Figures & Tables: All relevant photographs, graphs and diagrams should be named as Fig… and numbered, and along with captions they should be embedded in the manuscript. Please refer to each figure in the text of the manuscript as Fig. 1, Fig. 2, etc. A line bar should be appropriately placed in each figure indicating the magnification and defined in the legend.

Authors are encouraged to provide figures in colour for the online version. However, together with the colour figures authors should also provide clear black and white versions of the figures for the printed version of the journal. Multi-part figures should be labelled with uppercase letters (A, B, etc.). Inside the figures, Times New Roman 16pt (or larger) font is recommended. Figures may be sized to fit approximately within the column(s) of the journal; two-column wide figures are acceptable. Avoid using any type of shading in computer-generated figures. For accepted manuscripts, high quality figures (jpg or tif, not more than 1MB each one, in about 300dpi) should be sent separately and not be embedded in the text. Table text should be in Times New Roman 10pt font. Authors are encouraged to keep all tables within one or two column widths (portrait A4 page). Please refer to each table in the text of the manuscript as Table 1, 2 etc. Figures, tables, and their captions should be self-explanatory; e.g. abbreviations must be defined again here.

Abbreviations: Define abbreviations and acronyms in the ‘Abstract’ and at first mention in the main text, and thereafter use the abbreviation only. If there are several abbreviations, include a list of abbreviations and their definitions immediately after the Key Words.

Genus and species names must be in italics; write the genus name in full at first mention in the text and abbreviate whenever mentioned again. When referring to a species, do not use the genus name alone, unless you have previously defined it that way; be precise when using 'sp.' (singular) and 'spp.' (plural.) Please follow the latest I.C.B.N & I.C.Z.N. taxonomy or consult the WoRMS web site.

Equations and units: Use standard SI units. Variables are usually italicised. Italicisation should be consistent throughout the text. Leave one blank space on either side of '=', '>', ‘±’, etc. where these denote equalities or inequalities. Example: 'x = 3.6; p < 0.05; but: 'only three individuals measuring >20 cm in length were found'.

Geographical coordinates: The location of the geographical coordinates should follow the Decimal Degrees (DD) ° written format, e.g. 38.57653° Ν, 121.49317° W.

Acknowledgements: please provide a brief paragraph recognizing the source of funding for the work and acknowledging the assistance of individuals or organizations not identified in the list of authors.


Submissions that do not apply the reference format of the journal will be rejected by the editor and will not be forwarded to section editors/reviewers.

All quoted literature must be listed, and all listed literature must be quoted. References should be kept to an essential minimum and must be listed in the Reference list, in alphabetical order, and then chronologically. The order of references in the list should follow the example (please note that in cases where the number of authors exceeds 3, then the references should be listed in a chronological order):

Citations in the text should be identified by means of an author’s name followed by the year of publication of the reference (Author, 2011). When there are two authors, both names should be mentioned and separated by ‘&’ (Author 1 & Author 2, 2009). When there are three or more authors, only the name of the first author should be mentioned, followed by ‘et al.’ in Italics and the year of publication (Author 1 et al., 2012). If a cited author has published two or more papers in the same year, the references, both in the text and in the reference list, should be identified by a lower case letter, such as ‘a’ and ‘b’, after the date to distinguish the papers (Author, 2006a, b). Semicolons should be used to separate more than one citations, which should be in chronological order (from the earliest to the latest) (Author-A, 2005; Author-B & Author-C, 2010a, b; Author-D et al., 2012.) In cases of multiauthorship (more than 5 authors) only the first five appear in the reference list.

Satisfying FP7 and Horizon2020 Requirements for Open Access

As an open access journal, Mediterranean Marine Science helps you satisfy the open access requirements set by the European Commission for peer-reviewed research publications funded by FP7 and Horizon2020. Additionally, the journal is linked to the central repository where all open access research outputs funded by the EC are collected, OpenAIRE (www.openaire.eu). To make your article visible with this central repository, MMS requires that you enter the grant agreement number of your project in the relevant field while submitting your article with the journal, if your article is the result of EC-funded research. If your article is published, it will be harvested by and its metadata become available through that central repository.


Revised Submission


After incorporating the referees’ comments authors are required to send their revised and final submissions. This final document should be sent as a Word file and should contain a front page which will be the first page of the published article and should contain the following metadata information as has been submitted in the first submission of the paper: Title of the article (preferably not more than 100 characters, i.e. ~15 words -2 lines in print); Names of all contributing Authors (use * to refer to a footnote that identifies the corresponding author and provide her/his e-mail); Affiliations and full Institutional Addresses; Abstract (no more than 250 words; it should briefly describe the methods, results of research and conclusions; it should consist of a single paragraph and contain no citations or footnotes); and Keywords (no more than 8; preferably from the ASFA database Thesaurus; preferably different from those specified in the title of the manuscript.)

Images and other files for the final submission should be uploaded to the system as supplementary files, including black-and white images for the print edition and any other supplementary materials. High quality figures (jpg or tif, not more than 1MB each one, in about 300dpi) should be uploaded separately and not be embedded in the text.(see below, electronic supplements).

At this stage of the procedure, for non-native English speakers, it is necessary to check the revised version of your manuscript by a professional English editor. For professional linguistic services you may contact Dr Nathalie Yonow:n.yonow@swansea.ac.uk

or http://www.litterae.gr, for biologists, or other professional proofreaders. such as : http://www.journalexperts.com, http://www.globaledico.com/price.phpetc,

https://sciencedocs.com/ (offer the authors an introductory 15% discount)

You are expected to send the corrected paper along with certificaton of the professional proofreading.

This final document will be sent for layout, and proofs will be sent to the corresponding author. Corrections should be restricted to typesetting errors. Any queries should be answered in full. Please note that authors are urged to check their proofs carefully before returning them, since the inclusion of late corrections cannot be guaranteed.  Proofs are uploaded to the system for review by the Editorial Office as enhanced pdf documents with red markups for corrections inserted by computer, or as scanned documents with corrections marked in red color.

Titles of accepted manuscripts are added to ‘Early View’ publications on the MMS Web site, together with a prepress abstract. Articles are published online soon after the corrected proofs have been returned by the corresponding author.


Electronic supplements

Material which cannot be accommodated in the printed journal or is in a format unsuitable for inclusion within the article, may be published on the MMS web-site as an electronic supplement, with a direct link from the online article. Examples of such supplementary material are technical appendices, extensive simulation studies, lengthy data-sets, overlong tables, mathematical derivations, audio or video clips, and computer code. Supplementary material does not constitute a separate publication but is an electronic analogue of what might otherwise have been a set of appendices to the published paper. Supplementary Material must be closely integrated with the article itself and should not be misused as a convenient way of disseminating large amounts of extra information. It must be carefully prepared, as it will not go through the full prepublication process of checking and copyediting. Inclusion of material in the electronic supplement is at the discretion of the Editors.

The supplementary material should be presented as a self-contained document, headed by “Supplementary material to. . .” followed by the title, author, and author's affiliation, exactly as for the paper  itself. Please number supplementary figures using the format Fig. S1, Fig. S2, etc. Tables should be prepared using Times New Roman font and should be submitted as a Microsoft Word file. Please number supplementary tables using the format Table S1, Table S2, etc. Please use a separate numbering system from that used in the main article. Audio or video clips should be accompanied by a separate text (Microsoft Word) file containing titles and captions. Please keep captions as short as possible and ensure that captions of video clips explain what is being shown in the movie and any necessary details of how the movie was made.



Research published in MMS journals must have been conducted in accordance with institutional, national and international laws and guidelines concerning the use of animals in research and/or the sampling of endangered species.

The authors of a manuscript should refrain from plagiarism (total or partial submission of the work of others), fabricating (falsifying) data, dishonesty (altering or suppressing information), and submitting information previously published or under consideration for publication in another journal.

All persons who have made a significant scientific contribution to the research work and who share responsibility and accountability for the results reported in the submitted manuscript should be included as co-authors. Submission by the corresponding author implies that a draft copy of the manuscript has been provided to all living co-authors who explicitly approved its co-authorship prior to submission for publication; the date of death of deceased co-authors should be indicated in a footnote. Other contributions, including major administrative assistance, may be indicated in the acknowledgments.

Private information obtained through discussion, conversation, correspondence with third parties, or secured through confidential services, including refereeing manuscripts or grant applications, should not be reported without prior permission.
