General instructions

The following checklist will help you make sure that your manuscript will have a good chance with editors and reviewers. Please tick each box only after you are sure that your manuscript complies: most of these instructions are part of science everywhere, and their value has been proven over many years.

❏ TEXT: Follow the standard structure of a scientific paper (do not merge results with discussion). Apply an automatic spell checker, and provide the total number of words at the foot of the first page.

❏ IMAGES: Attach sharp photographs at 300 DPI and illustrations at 600 DPI (we accept JPG, TIFF, PNG and Photoshop). Very important: all figures should have labels using Helvetica 10 points as their font type and size (check our Figures Guide)

❏ UPLOAD your manuscript and attach a scanned copy of the submission letter signed by all coauthors (download letter here). The submission system will immediately confirm reception. If you have problems, check our FAQ.

❏ The manuscript is either a review or a research article that meets the requirements of our scope.

Introductory section

❏ In the title, use capital letters to start proper names. The title must be short and include, in parentheses, Order and Family (botanical papers: only Family). Do not use local names in the title.

❏ For taxonomy articles only: include full genus, author and year only the first time each taxon is mentioned in each article section.

❏ The address for correspondence must be short but complete; if there are several addresses, numbered them. Include valid e-mails for all coauthors.

❏ The Abstract (350-450 words) must have five subtitles: Introduction; Objective; Methods (include study period and sample size); Results and Conclusions (see examples in recent articles).

❏ Include 5-7 key words that do not appear in the title or in the abstract (if you have doubts see a recent article).

❏ Include an introduction that summarizes recent findings in chronological order and ends with the objective of the study.

Material and Methods

❏ Present only the information required to repeat the study. For previously published methods, a brief description and the reference are enough.

❏ Do not include a map for just one study site; instead, provide its geographic coordinates. A map is appropriate for studies with various sampling locations or when additional information, such as vegetation, is needed.

❏ If voucher specimens were collected, include museum data.

❏ Only include equipment model and manufacturer when these could affect the results. For chemical products just name the manufacturer.

❏ Include a description of each component for mathematical formulas.

❏ Avoid acronyms, but if you must use them, explain the first time, for example: “RBT (Revista de Biología Tropical)”.

❏ We use the International System of Units and their abbreviations, except that decimals are indicated with a period, thousands and millions with a space, eg. 12 523 235.15

❏ When not followed by units, write integers from zero to ten in full (one, two etc., not 1, 2 etc.).

Results

❏ Avoid “Statistics” sections in the paragraphs, it is often better to present the data after each result and in parentheses, for example: “Height and speed were positively correlated (Spearman, p< 0.05)”, or even better: “Taller individuals were faster (Spearman, p< 0.05)”.

Tables and Figures

❏ Avoid isolated figures by grouping related photographs, graphs and other illustrations. Include all symbols and scales inside the figure (not in the figure caption). For better graphs read here.

❏ If the manuscript is written in Spanish, please use the word "Tabla" instead of "Cuadro" throughout the manuscript.

❏ Use short table headings and move all symbols and abbreviations to the footnotes under the table. Avoid words written fully in upper case or in bold font. Avoid long or very short tables (half to one page long tables are a good size), and do not insert vertical and horizontal lines.

Discussion

❏ This section compares your results with previously published data. Do not include tables or figures here.

Acknowledgments

❏ Only mention persons who gave significant assistance. “Dr.”, “Prof.”, “Mrs.”, among others, are not used, only names.

Resumen and Palabras clave

❏ These are the Spanish versions of abstract and keywords. Our staff will translate them, free of charge, for authors who do not speak Spanish. For everyone else: please start with the title of the article in Spanish and make sure that the Spanish and English versions match.

References

❏ Present the list of references and citations within the text in APA 6th Edition format. We recommend the use of free reference managers like zotero.org and mendeley.com.

❏ Only cited publications appear under References and vice versa. Unpublished papers are mentioned in the text as in this example: (J. Smith, unpublished).
