Preparation of the manuscript
To assist authors in preparing their manuscripts a template is provided at the following address:


The use of this template is highly recommended because it contains additional instructions and the format usually employed in the journal. When using the template, just substitute the provided text in each section by your text.

Manuscripts (maximum extension 6000 words, excluding tables and figures) will be typed, double-spaced, on A-4 sheets (210 x 297 mm) leaving 30 mm margins. Lines should be numbered. The various sections of the manuscript should be assembled in the following sequence:

Title, Authorship, Abstract, Keywords and ORCID (page 1)
Introduction (page 2)
Materials and Methods
Authorship contribution statement
Tables (each in a single page, with its legend)
Figure captions (all combined in one or as many pages as needed)
Figures (each in a single page)

All headings will be in bold capitals.

The first page should include the title of the paper, the authors’ names, the name and address of the institution where research was done, the e-mail address of the corresponding author and the ORCID of each of the co-authors who have participated in the manuscript in the URL format: One NI (find your ORCID in More information on our downloadable template.

The Abstract and Keywords will include the title of the article, a 100-150 words abstract (written in third person), and 3 to 6 keywords for indexing and aiding the reader in literature retrieval. If possible, translate this page to Spanish.

Tables and figures will be printed in separate A-4 sheets. Minimum required resolution for figures at the final reproduction size is 600 dpi.

The submission (including the title and abstract page, the other sections of the body of the paper, the tables, and the figures) should be in one file. Use of Microsoft Word 97 or higher is preferred.

Symbols, units and nomenclature
The authors should follow the rules of the Système International d’Unités (SI). Chemical nomenclature should follow as closely as possible the IUPAC rules.

Tables and figures
Results must be presented in a maximum total of 8 figures and tables, not in both forms at the same time.

Tables and figures will be separately numbered in Arabic numbers, in the order that they appear in the text. Both should have an explanatory legend.

Graphics must be clear (avoid using grids as well as shades of gray on bars or lines). Their dimensions must be such that remain clear and legible after size reduction to 8, 12, or 16 cm width. For letters and numbers use Sans-Serif characters 4 mm in height; line thickness must be 0.4 to 0.6 mm; broken lines or cycles should be 4 to 5 mm long after reduction.

Photographs should have the greatest contrast possible and be submitted as JPEG file (or similar), all of them stored in a single ZIP or RAR compressed file.

All figure legends should be combined in one list and typed on a separate sheet.

Transparencies, slides, dot-matrix computer graphics, photocopies or original instrument recordings will be rejected.

Please notice that Digital Object Identification (DOI) should be included into each reference whenever available. The complete Cross Reference guidelines can be found in the CrossRef web site (

References should be cited in the text by the authors’ names and year of publication (Harvard system). Thus, they can appear as “according to García-González et al. (2007)”, if the name of the author is cited in the text, or “(García-González et al., 2007)” at the end of a sentence.

Use a letter after the year if more than one reference for the same authors and year is given. They should be ordered by the publishing year if several references are used at the same time.

The full list of references should be typed at the end of the paper in alphabetical order, according to the following examples:

Research data policy

We recommend authors depositing data obtained from the research developed for the preparation of their article in repositories of recognized prestige, specific to the discipline or of a generalist nature. In any case, it must be a FAIR repository (Findable, Accessible, Interoperable, Reusable), preferably in open access.

There are several repositories destined to conserve and disseminate concrete data such as results of surveys, observations, interviews, simulations, automatically collected data, samples, models ... If necessary, authors can consult the Registry of Research Data Repositories re3data taking into account that each repository has its own deposit rules.

Those CSIC authors who would like to deposit their datasets in Digital.CSIC may do so by following these guidelines. They can use the Servicio de Archivo Delegado made available by the Technical Office of DIGITAL.CSIC and the Red de Bibliotecas CSIC.

DIGITAL.CSIC generates DOIs for datasets and associated software and is certified as data repository in re3data and Repository Finder. More information at Política de datos en Digital.CSIC.

If the author has deposited datasets in a repository, he should mention it in the article providing a brief description of the type of data deposited, the name and URL of the repository, the identification code and the data of the license for use and distribution.
