Author Guidelines
EDITORIAL GUIDELINES FOR REVISTA MEXICANA DE MASTOZOOLOGIA (RMM)
In Revista Mexicana de Mastozoologia, nueva epoca, works are considered for publication on any aspect related to mammals, with special interest in Mexican mammals, but preferably those that address issues of biodiversity, biogeography, conservation, ecology. gy, distribution, inventories, natural history and systematics. Preference will be given to works that represent original contributions to the exercise of mastozoa. ology, without restricting itself to any specific topic. All submitted works will be reviewed by two expert referees on the subject of the work presented. The works submitted to the magazine can be in the form of a research article, hundredth note typology or review article. Manuscripts should not exceed 20 pages for articles and 8 for grades. It is preferable that manuscripts be submitted in Spanish; however, it is also They will accept papers in English with their respective Summary. The manuscript must be accompanied by a cover letter detailing the relevance of the research and the relevance of its publication in our magazine; In the same way it can be proposed ner to two potential reviewers.
I. GENERAL FORMAT
All the manuscripts send to the Revista Mexicana de Mastozoología, nueva época for potential publication, must conform to the following format:
A) Text
The document must be prepared using the latest version of Word, in upper and lower case, with Times New Roman font, 12-point font size, and double line spacing. Paragraphs should be double- spaced and indented 5 points at the beginning, except for the first paragraph of each section, which should not be indented. All margins, both side and top and bottom, must be 3 cm. The right margin of the text should not be justified, and all pages must be numbered in the upper right corner. Do not use a cover page: the first page of the manuscript should be the one on which the abstract begins. Avoid using
Avoid the use of anglicisms or gallicisms. Capital letters must be accented, and the manuscript should generally be written in accordance with the grammatical rules accepted for the Spanish language and following the recommendations established by the Dictionary of the Royal Spanish Academy. Italics are used for scientific names, statistical terms, and mathematical symbols in equations or those used to denote statistical tests. Graphs and images, both figures and photographs, should be submitted separately in their respective formats, preferably in color. Graphs from Microsoft Excel should be included in their original file, and those from statistical software programs and images in *.jpg, *.png, or *.tiff format should have a resolution minimum resolution of 600 dpi.
B) Headings
Their position indicates the hierarchy of each part of the contribution and has various levels. The order used in the RMM is as follows: headings appear only in articles and not in notes, followed by free text. They can be of three types: primary (bold, left-aligned, and in all caps with accents), secondary (left-aligned, in mixed case, and bold), and tertiary (left-aligned, in mixed case, and italicized). Not all papers necessarily need to include all three types of headings.
Primary headings may only include, depending on the characteristics of the work, some of the following: Abstract, Introduction, Study Area and Methods, Methods, Results and Discussion, Results, Discussion, Discussion and Conclusions, Conclusions, Acknowledgments, Literature Cited, and Appendix.
C) Bibliographic citations in the text
To cite sources in all contributions, the APA style will be used. Author-year: Author(s) and year of contribution, in parentheses. However, the way the system is applied will depend on the wording in each paragraph or on the respective sentences. When citing a single author, place the first surname and the year of publication in parentheses, with the appropriate punctuation mark between the two elements. Example: (Arellano, 2025). When there are two authors, include the first surname of each, separated by the conjunction “y.” Example: (Ramírez-Mejía and Sánchez, 2015). If the citation corresponds to three or more authors, it should be formatted as in the first case, adding the Latin phrase et al. in italics and the year. Example: (Gordillo-Chávez et al., 2023). When citing multiple works at once, they should be ordered alphabetically and then chronologically; they should be separated by semicolons. Example: (Ceballos and Oliva, 2005; Guevara and Cervantes, 2019; SEMARNAT, 2019).
When citing authors who have published more than one reference in the same year, or when citing them in the same way in the text, they will be distinguished by the letters a, b, c, etc., placed immediately after the year of publication (e.g., Ceballos et al., 1993a; Ceballos et al., 1993b) and added to the contribution’s reference section in alphabetical order. Also, when citing electronic publications or web pages, the same format will be used. When the author wishes to cite unpublished information—although this should be avoided—any verbal or personal communications relevant to the contribution must be indicated in parentheses as (pers. comm.). In any case, all references cited in the text must be included in full, without exception, in the corresponding section.
II. ELEMENTS OF CONTRIBUTIONS
Title
It will be brief, concise, and should reflect the content of the contribution. It will be entirely in uppercase, except for scientific names, which will have the first letter of the genus capitalized and must be italicized; it will not include authorities’ names or dates for the scientific names. It must be centered, in bold, and must not end with a period. Both the Spanish and English titles will be included.
Authors
In hierarchical order according to their degree of collaboration. Authors will include their full names, or as they wish them to appear, separated by commas, and there will be no period at the end of this section. It is important to include the ORCID IDs of all authors. Their affiliation should be centered, without academic degrees or job titles, in plain text, and with initial capital letters. At the end of each name, a progressive numerical subscript will be added, and in the address section, the institution’s name, full address, and available email address will be indicated for each subscript. If all authors belong to the same institution, only one subscript will be used. In addition to indicating the corresponding author with an asterisk.
Abstract
This is a faithful translation of the abstract into English. It is the author’s responsibility to submit this section in its entirety, even if it is subsequently edited. If the manuscript is in English, the abstract will be placed first.
Key words
Faithful translation of the keywords into Spanish. With the same rules and in alphabetical order.
Relevance
It is a very brief paragraph of one or two sentences that mentions the importance of the work.
Introduction
The importance of the problem, the justification for the research, the specific background, the objectives, and the hypotheses will be highlighted. The background should refer to recent literature, preferably from the last decade, except in cases where manuscripts concern descriptions or changes in the current distribution of species, in which classical literature on the topic will likely be required to provide support.
Materials and Methods
The procedures and methods employed shall be stated clearly, briefly, concisely, and in an orderly manner, specifying the units of measurement, variables, and statistical treatment, so that the experiment and analyzes can be replicated. It is mandatory to cite the bibliographic references for the methods described. The materials and equipment mentioned must highlight models, brands, or patents.
Study area
This section includes the study area, which, in addition to being described in the text, should preferably be accompanied by a figure. The figure should be a map that includes the basic elements: scale, geographic north reference, projection, and ideally a reference grid.
Results
They will be presented in an orderly, clear, and precise manner. The description of these will consist of indicating the fundamental interpretation of the tables or figures without repeating the data described therein.
Tables
They should be included on separate sheets and cited using Arabic numerals. Each table will be cited in the text. The approximate position of the table in the printed paper will be indicated in the same way as for figures.
Figures
Figures must be presented in their final version. Group together the illustrations that need to be presented and plan them carefully, considering the scale and technique used. Do not submit the original figures with your initial manuscript submission; instead, include clear, high-quality copies at the end of the manuscript, on separate, unnumbered sheets. The original figures will be requested once the manuscript has been accepted. Electronic illustrations should be in Microsoft Excel (graphs) or in *.jpg, *.png, or *.tif format (both maps and photographs) at a minimum resolution of 600 dpi and preferably in color.
Be careful that the data presented in the figures are complete, including axis titles, scale, and any other element that helps understand the figure. Authors may submit a color photograph for consideration as the cover image in a separate file.
Figure captions
They should be included at the end of the manuscript. Their position in the final version should be indicated in the approximate area in the left margin of the text, enclosed in brackets (e.g., [Figure 1]). These captions should be clear and explain in detail what the figure shows, and include credits for photographs or maps. (e.g., Photo: Heliot Zarza).
Measurements and numerical annotations
Use decimals instead of fractions. The names of numbers from one to nine should always be written out, except when they appear in a series of numbers that includes larger numbers (e.g., 1, 7, and 18 or three wolves and eight bears), when referring to units of measurement (e.g., 3 min, 8 days), or at the beginning of a paragraph. When mentioning measurements of weight or volume or common units, use the abbreviations of the International System of Units without a period (e.g., 20 kg, 30 km, 5 m, 2 ha), and when referring to time measurements, use “h” for hours, “s” for seconds, and “min” for minutes. Use commas to separate groups of three digits in numbers of thousands or greater, and use a period to indicate decimals (e.g., 3,000; 6,534,900; 1,425.32). The mathematical symbols used in equations and formulas may include the basic ones (+, −, x², 1, <, >, =, *) and any additional symbols, provided they are properly defined in the methods section. Always use the decimal metric system to indicate weights, distances, areas, and volumes, and use degrees Celsius for temperatures. The only exception to this rule is the use of hectares (ha), which should be adopted whenever the area indicated is in the tens of thousands of square meters.
Statistical terms such as G, h, l, and other single-letter abbreviations may be used after they have been defined the first time they appear. Terms that are abbreviated with multiple letters (e.g., ANOVA) must be written out in full. Don’t forget that these should also be underlined and italicized in the final text.
Systematic treatment
The nomenclature of all mammals discussed in papers submitted to the Revista Mexicana de Mastozoología, nueva época, for publication must be based on the work of Wilson and Reeder. Scientific names must be italicized. After first mentioning them (e.g., Heteromys pictus), the generic name should be abbreviated (e.g., H. pictus), except at the beginning of a paragraph, in titles or headings, or when there is confusion with other cited species.
Discussion
It consists of explaining the interpretation of the results obtained by drawing on appropriate bibliographic citations, as well as comparing the most relevant findings with those of other authors who have presented similar work.
Conclusions
This section should briefly and precisely highlight the concrete contributions of the study’s results, referring only to the submitted manuscript and not considering external documents or assumptions.
Acknowledgments
It will be included only if the author wishes to acknowledge individuals or institutions that provided logistical and financial support for the development of the research work. However, we urge authors to include the institutions that funded the project.
Cited Literature
In this section, the bibliography should always be arranged alphabetically by author, regardless of the format of the information—whether books, theses, journal articles, etc. The initials of each author’s first name and second surname should be written without spaces and with a period. If there are multiple citations by the same author, they will be ordered chronologically.
Likewise, if there are two identical dates by the same author, they should be distinguished with the letters a, b, c and cited accordingly in the text. All publication titles must be written out in full. It is recommended that if a citation includes more than seven authors, the phrase et al. (in italics) be used after the third author. Carefully verify that all references cited in the text are included in this section and that all references in the Literature Cited are mentioned in the text. If this list is not consistent with the text, the manuscript will be automatically rejected by the general editor.
