Guidelines for drafting the article

1. The title of the manuscript, depending on the type of work, should not exceed 80 characters. It should be in lower case and bold, Times New Roman 12 font. It should be sent in Spanish and English and should be written in a single column.
2. Type the text in Word for Windows, with margins of 2 cm on the right-hand side and 2.5 cm on the bottom, left and top of the page.
3. Typeface: Times New Roman,
a. Font size for text and content: 10 cpi. except for title in Spanish and English which will be displayed in 12 cpi.
b. Font size for title: 12 cpi.
c. For paragraphs: 10 cpi.
d. Line spacing: 1.5 cm.
Page numbering: bottom centre, Times New Roman 9 cpi. Numbering is sequential, starting from the abstract.
5. Prepare as many tables and figures as possible in Word and Excel.
6. Do not use words written entirely in capital letters, except for subtitles (e.g.: I. INTRODUCTION, etc.), and acronyms with up to four (4) letters (e.g.: OE, Opanal, Unesco).
7. Use italic format for taxonomic genus and scientific names of species, subspecies and Latin locutions (e.g. Phaseolus, Zea mays, vox populi, ipso facto).
8. Write the full scientific name of each species when it is mentioned for the first time; in the following citations, the first one referring to the genus should be abbreviated by its initial letter. Maintain these rules in tables and figures, whenever possible.
9. Use boldface only for titles and subtitles (e.g., ABSTRACT, ABSTRACT, I. INTRODUCTION, etc.).
10. Write single-digit numbers in letters (e.g. six individuals), unless they are used with units of measurement (e.g. 7 cm), use numerals for numbers of two or more digits (e.g. 15) and space after each group of three digits (e.g. 142 000 and 69 000), except in calendar years (e.g. 2025).
11. Keep syntax simple and consistent. Check that the neologisms to be used belong to the international scientific and technical vocabulary.
12. Citations in the text should be described with the surname of the author(s) and the year of publication, both in parentheses, with a comma separating them, for example: (Gil-Martin, 2013). In the case of two authors, for example: (Delgado and Mera, 2022). In cases where the work is by more than two authors, the surname of the first author will be cited followed by "et al. (in italics) to refer to the rest of the authors. (Sánchez et al., 2020).
13. When there are institutional authors (OEFA, UN, etc.), their acronyms and the date should be cited in the text (for example: OEFA, 2018; UN, 2022), and in the bibliographical references the initials should be placed first and the full name of the institution in brackets.
14. In the final section of bibliographical references, the citations should be ordered alphabetically, starting with the surname of the first author, and in chronological order.
15. Times New Roman 10 should be used, with 1.5 line spacing and French indentation. To connect the surnames in the case of two or more authors, ‘y’ should be used in Spanish and “and” in English; the symbol ‘&’ should not be used throughout the text.
16. Avoid writing in the first person singular or plural (e.g. ... in my work I set out to investigate...). The impersonal style should be used (e.g.: ... in this work I investigated...). For the scientific article the writing is in the present or past tense.
17. The images to be used in the scientific manuscript must be in JPG format of 300 dpi. The manuscript should be structured in this order: title, author(s), affiliation, summary, abstract, introduction, materials and methods, results, discussion, or results and discussion, conclusions, acknowledgements (optional), authors' contribution, conflicts of interest and bibliographical references, tables (optional), legends and figures (optional).
