Instruction for Authors

As of January 1, 2020, Comptes Rendus - Biologies no longer accepts unsolicited submissions.

This website is therefore closed to new submissions.

Only articles requested by the Editorial Board will be published.


—Preparation of the manuscript


   Submission Formats

Manuscripts must be sent on OJS simultaneously in two formats with line numbering: Word or LaTeX and PDF format.

If you submit a Word format, please number the lines of your file before exporting it into PDF (PDF shall also have lines numbered).

To number the lines, go to the Layout tab of your document (in the Page Setup group) and click on Line Numbers / Continuous.

To know more about the operation, pleas visit the support office page.

If you forgot files during your initial submission :

  • if the missing files are numerous and / or significantly change the content of the submission: it would be better to abandon the initial submission and make a new submission
  • otherwise: you can open a discussion with the editor, attach the missing file(s) and ask the editor to add them


   General information for Word and LaTeX formats

Word Formats
  • It is important that the file be saved in the native format of the word processor used.
  • The text should be in single-column format. Keep the layout of the text as simple as possible.
  • Most formatting codes will be removed and replaced on processing the article.
  • In particular, do not use the word processor's options to justify text or to hyphenate words. However, do use bold face, italics, subscripts, superscripts etc.
  • When preparing tables, if you are using a table grid, use only one grid for each individual table and not a grid for each row. If no grid is used, use tabs, not spaces, to align columns.
  • Note that source files of figures, tables and text graphics will be required whether or not you embed your figures in the text.
  • Please note that the paper submitted must be written in a correct language. Any article received in an approximate English or French will be refused immediately. Authors have the possibility to turn to automatic correctors, DeepL type.
  • Note that every accepted article will be converted into LaTeX format for publication.
LaTeX Formats

Authors are invited to prepare their article with PDFLaTeX (for submission or after acceptance), the bibliographic references stored in a bibtex file, illustrations preferably as PDF, with a sufficient quality for unambiguous Web display or print. Authors are strongly encouraged to use the journal's LaTeX class file and bibtex style, but amsart or smfart classes, as well as amsplain and smfplain styles are accepted. Please refer to the instruction page for papers prepared with LaTeX (under construction).


—Composition of the manuscript


  Length and language

Articles can be submitted either in French or in English, but preferably in English.


   Organization (in order of appearance)

  • title page: title in French and in English (20 words maximum), full first name, family name and affiliation of each author; postal address, phone and fax number, e-mail address of the corresponding author;
  • short abstract (100 to 150 words) with keywords (7 maximum) in French and in English (translation from English to French can be made by the Editorial Board, on request);
  • abridged English version, if the article is written in French;
  • text of the article;
  • acknowledgements (optional);
  • bibliographical reference list;
  • figure and table captions;
  •  figures;
  •  tables.


   Bibliographical references

References must be numbered and listed sequentially as they appear in the text. The list must include all references quoted in the text and in the figure and table captions.

Journal titles must be abbreviated according to international rules. Do not use italics and bold for journal titles and volume numbers.

Examples (all authors must be indicated):

  • Article
    [1] W.J. Graigen, C.T. Caskey, International frame-shifting: where will it stop?, Cell 50 (1987) 1–2.
  • Book
    [2] M.B. Brown, Cotton: history, species, varieties, morphology, breeding, culture, diseases, marketing and uses, McGraw-Hill, New York, 1938.
  • Chapter in a book
    [3] S. Kubin, Measurement of radiant energy, in: Z. Sestak, J. Catsky, P.G. Jarvis (Eds.), Plant Photo-synthetic Production. Manual of Methods, Junk, La Haye, 1971, pp. 702–765.


   Illustrations (graphics, plates, photographs, etc.)

These must all be labelled as figures and numbered using Arabic numerals. If possible, please submit them in their final size (75 mm width). If they are wider than 1 column (to be avoided if possible), their width must be no more than 160 mm. Tables must also be numbered in Arabic numerals. All figures and tables must be quoted in the text. Figures must be free of copyright. If re-using a figure already published, the authorization of the publisher of the original article is necessary, as well for paper as for electronic publishing.


   Equations and mathematical or chemical formulae

These must be clearly set out: exponents and indices should be carefully placed (write x1 instead of x1); avoid ambiguous expressions such as 1/2x: write either 1/(2 x), or (1/2) x ; the same quantity should be always indicated by the same symbol, in the same font. Please respect the usual typographic rules: for instance, mathematical or physical quantities, such as the x axis or a mass m, must be written in italics. So + 1 de l will be distinguished, as well as the logarithm ln and the product of l by n.
