Scope and general guidelines

Revista Brasileira de Biologia publishes the results of original research in any field of Biological Sciences. It encourages publication of works in Cell Biology, Systematics, Ecology (Self-ecology and Synecology) and Evolutive Biology addressing neotropical region problems.

The Revista publishes only articles in English. Review articles on general topics will be published if submitted to and approved by the Editorial Board.

General Information: The originals should be submitted to the Editorial Board and comply with the Instructions to Authors, and the papers that do not meet the requirements will be immediately returned to the authors for alteration.

The works that comply with the Instructions to Authors will be sent to scientific advisors, indicated by the Editorial Board. In each case the opinion will be anonymously sent to the authors. In case of unfavorable recommendation by one advisor, another referee will be asked to give his/her opinion. The articles will be published in order of approval by the Editorial Board and not in order of receiving. Twenty-five reprints of each article will be provided for free.


Preparation of originals

The work to be considered for publication should comply with the following general recommendations: typed and printed on one side of A4 paper, double-spaced, with a 3-cm left margin and 2-cm right margin. The lines should not be justified on the right side and there should be no hyphenation in the end of the line. The words to be printed in italic could be underlined.

The title should give a precise idea of the content and be as short as possible. An abbreviated title should be provided to be printed on headings of the pages.

Name of authors – The surnames Júnior, Filho, Neto, Sobrinho, etc. should always be preceded by a hyphen, for example, J. Pereira-Neto. Use hyphens for compound names (for instance, C. Azevedo-Ramos, M. L. López-Rulf). The name of the authors should always be in the correct order, with no inversions. Never use as authors or co-authors names such as Pereira-Neto J. Use and and et instead of & to connect the last co-author to the first ones.

The typescripts should be written in a concise, accurate and clear manner required for full understanding. The writing should be definite in order to avoid modifications in the proofs, which are costly and will be paid by the authors. The manuscripts (including illustrations and tables) should be sent in three copies (one hardcopy and two photocopies).

Only articles written in English will considered for publication. All articles should have abstracts in English and Portuguese. These abstracts should be inserted in the beginning of the article and begin with the title translated to the corresponding language. The Abstracts should contain the same information and always provide a summary of results and conclusions.

By and large the different parts of the articles should have the following content:

1st page – Title of the article. Name of authors. Name and address of the institution. Indication of the number of figures included in the paper. Key words in Portuguese and English (maximum of five words). Abbreviated title for page headings. Footnote: name of the corresponding author and current address (if applicable).

2nd and subsequent pages – Abstract (no title). Abstract: in Portuguese (with title); Introduction, Material and Methods, Results, Discussion, Acknowledgements.

In a separate page – References, Legends of figures, Tables and Figures.

The paper should not exceed 25 pages, including tables and figures.

The subdivision of Introduction and Acknowledgements section should be used only if really applicable. The other articles (such as Systematics) should be prepared according to the criteria usually accepted in this field.

References – In the text, use authors–year for bibliographical citations, and use ampersand (&) in case of two authors. The references, typed on a separate sheet, should be in alphabetical order and include name and initials of authors, year, full title, name of journal (abbreviated and underlined), volume and the first and last page numbers. Citations of books and monographs should also include the publisher and, if applicable, indicate the chapter of the book. The name of the editor(s) of the collection should be indicated.

The journal publishes a Content list in English to be used in international reference journals.

The proofs are sent to the authors for a final proofreading (restricted to errors and writing) and should be immediately returned. The proofs not returned within the period required - 5 days - should have their publication postponed to a later date, depending on availability of space.

Illustrations – The authors should limit tables and figures (both should be referred in consecutive Arabic numbers) to what is strictly necessary. In the typescript text, the authors should indicate where they will be inserted.

The tables should have a title and, in a footnote, other explanatory information. Symbols and abbreviations should be defined in the main text and/or legends.

When preparing illustrations and tables, bear in mind the size of the journal page (22 cm x 15.0 cm) (column: 7 cm) and the idea of maintaining the vertical orientation. Drawings and photographs excessively large could be not very clear if reduced to the size of the journal. The boards should not be over 30-cm high and 25-cm wide, including calibration bars.

Whenever possible, group the illustrations. The Editorial Board is entitled to use this material in a more economical manner, not interfering in its presentation.

All drawings should be painted in China ink and submitted in such a way that its reproduction is possible with no retouch. Photographs should be in glossy paper. The photographs and tables should have the name of authors and title of the article written on their back, in pencil.

Diskette – The authors are highly recommended to send the final version (and only the final one), already accepted, of their typescripts in diskettes. The texts should be prepared in Word for Windows and sent together with a hardcopy.

Final Recommendations: Before submitting the paper, prepared according to the previous instructions, the authors should read it again carefully and draw attention to the following items: grammar check, spell check (just a syllable by syllable reading is enough), correspondence between the works cited in the text and listed in the references, tables and figures in Arabic numbers, correspondence between the number of tables and figures mentioned in the text and the correct position of the legends.
