The journal Anais da Academia Brasileira de Ciências from 2012 onwards only considers online submissions. Once you have prepared your manuscript according to the instructions below, please visit the new, improved online submission website at Please read these instructions carefully and follow them strictly. In this way you will help ensure that the review and publication of your paper are as efficient and quick as possible. The editors reserve the right to return manuscripts that are not in accordance with these instructions. Papers must be clearly and concisely written in English.


Aim and editorial policy

All submitted manuscripts should contain original research not previously published and not under consideration for publication elsewhere. The primary criterion for acceptance is scientific quality. Papers should avoid excessive use of abbreviations or jargon, and should be intelligible to as wide an audience as possible. Particular attention should be paid to the Abstract, Introduction, and Discussion sections, which should clearly draw attention to the novelty and significance of the data reported. Failure to do this may result in delays in publication or rejection of the paper. Articles accepted for publication become property of the journal.

Texts can be published as a review, a full paper (article) or as a short communication. Issues appear in March, June, September and December.

Types of Papers

Reviews are published by invitation only. A proposal for a Review must be sent to the Editorial Office (, which will proceed accordingly.

Whenever possible the articles should be subdivided into the following parts: 1. Front Page; 2. Abstract (written on a separate page, 200 words or less, no abbreviations); 3. Introduction; 4. Materials and Methods; 5. Results; 6. Discussion; 7. Acknowledgments, if applicable; 8. References. Articles from some areas such as Mathematical Sciences should follow their usual format. In some cases it may be advisable to omit part (4) and to merge parts (5) and (6). Whenever applicable, the Materials and Methods section should indicate the Ethics Committee that evaluated the procedures for human studies or the norms followed for the maintenance and experimental treatments of animals.

Short communications
Short communications aim to report on research which has progressed to the stage when it is considered that results should be divulged rapidly to other workers in the field. A short communication should also have an Abstract and should not exceed 1,500 words. Tables and Figures may be included but the text length should be proportionally reduced. Manuscripts submitted as articles but found to fit these specifications will be published as short communications upon the author’s agreement.

After the first screening, the articles will be evaluated by at least two reviewers, them being from educational and/or national and international research institutions, with proven scientific production. After due corrections and possible suggestions, the paper may be accepted or rejected, considering the reviews received.

We use the integrated Crossref Similarity Check program to detect plagiarism.

There are no APC and submission charges in the AABC.


Preparation of manuscripts

All parts of the manuscript should be double-spaced throughout. After acceptance, no changes will be made in the manuscript so that proofs require only corrections of typographical errors. The authors should send their manuscript in electronic version only.

Length of manuscript
While papers may be of any length required for the concise presentation and discussion of the data, succinct and carefully prepared papers are favored both in terms of impact as well as in readability.

Tables and Illustrations
Only high-quality illustrations will be accepted. All illustrations will be considered figures including drawings, graphs, maps, photographs as well as tables with more than 12 columns or more than 24 lines. Their tentative placement in the text should be indicated. The AABC do not charge the first 5 figures in black and white or scale of gray. Should the authors want colored figures in the hard copy, a cost may be generated for each one of them, as well as for each figure in black and white or scale of gray beyond 5. Figures that are published in colors only in the online version do not generate additional costs.

Digitalized figures
Figures should be sent according to the following specifications: 1. Drawings and illustrations should be in format EPS (PostScript) or AI (Adobe Illustrator) and never be inserted in text; 2. Images or figures in grayscale should be in format TIF and never be inserted in text; 3. Each figure should be saved in a separate file; 4. Figures should be submitted at high quality (minimum resolution of 300dpi) at the size they are to appear in the journal, i.e., 8 cm (one column) or 16.5 cm (two columns) wide, with maximal height for each figure and respective legend smaller than or equal to 22 cm. The legends to the figures should be sent double-spaced on a separate page. Each linear dimension of the smallest characters and symbols should not be less than 2 mm after reduction; 5. Manuscripts on Mathematics, Physics or Chemistry may be typesetted in ,  or . The TEX, PDF and BIB files should be sent, and EPS files if there are any figures; 6. Manuscripts without mathematical formulae may be sent in RTF, DOC or DOCX.

Front page
The front page of the manuscript should present the following items: 1. Title of the article (the title should be short, specific, and informative); 2. Full name(s) of the author(s); 3. Full professional address of each author (institution, street, number, zip code, city/county, state if applicable, country, etc.); 4. Key words (four to six in alphabetical order); 5. Running title (up to 50 characters); 6. Academy Section (one out of our 10 areas) to which the content of the work belongs; 7. Name and e-mail address of the author to whom all correspondence and proofs should be provided. Should any of these requirements not be met, we may unsubmit your paper and ask for corrections.

These should be included at the end of the text. Personal acknowledgments should precede those of institutions or agencies. Footnotes should be avoided; when necessary they must be numbered. Acknowledgments to grants and scholarships, and of indebtedness to colleagues as well as mention to the origin of an article (e.g. thesis) should be added to the Acknowledgments section.

Abbreviations should be defined at their first occurrence in the text, except for official, standard abbreviations. Units and their symbols should conform to those approved by the ABNT or by the Bureau International des Poids et Mesures (SI).

Authors are responsible for the accuracy of the References. Published articles and those in press may be included. Personal communications (Smith, personal communication) must be authorized in writing by those involved. References to thesis, meeting abstracts (not published in indexed journals) and manuscripts in preparation or submitted, but not yet accepted, should be cited in the text as (Smith et al., unpublished data) and should NOT be included in the list of references.

The references should be cited in the text as, for example, ‘Smith 2004’, ‘Smith and Wesson 2005’ or, for three or more authors, ‘Smith et al. 2006’. Two or more papers by the same author(s) in the same year should be distinguished by letters, e.g. ‘Smith 2004a’, ‘Smith 2004b’ etc. Letters should also distinguish papers by three or more authors with identical first author and year of publication. References should be listed according to the alphabetical order of the first author, always in the order SURNAME XY in which X and Y are initials. If there are more than ten authors, use et al. after the first author. References must contain the title of the article. Names of the journals should be abbreviated without dots or commas. For the correct abbreviations, refer to lists of the major databases in which the journal is indexed or consult the World List of Scientific Periodicals. The abbreviation to be used for the Anais da Academia Brasileira de Ciências is An Acad Bras Cienc. The following examples are to be considered as guidelines for the References.
