Instructions for authors



Manuscripts submitted to the Pan-American Journal of Aquatic Sciences must be original, not published before (except in the form of an abstract, or as part of a published lecture, or thesis), not under consideration for publication elsewhere and approved by all authors as well as by the responsible authorities - tacitly or explicitly - at the institute where the work has been carried out prior to submission. Our Journal will not be held legally responsible should there be any claims for compensation.


Authors are also responsible for obtaining the consent of their co-authors in order to include their names in the publication. Only the authors will be responsible for any disagreement arising after their article is published online at Pan-American Journal of Aquatic Sciences’ site. Once published, no request from any co-author to delete his/her name from the publication, or any sort of modification in the publication’s content will be accepted. In order to avoid authorship issues, please state in the cover letter that all co-authors agreed with its content and submission to our Journal, and that everyone meriting authorship have been so named.


Following submission, the manuscript will be pre-reviewed by the Editors and/or one of our Permanent Advisors (in the area of the manuscript). If pre-approved, it will be forwarded to three Reviewers according to the scope and specific area. Anonymity for both authors and reviewers will be preserved.


Acceptance will be based on the quality of the science, the appropriateness of the manuscript for our Journal and the quality of the English grammar. Authors whose mother tongue is not English must have their texts revised by a professional translator or an English native speaker colleague, otherwise will be rejected. Each manuscript must stand on its own merits and be a substantial contribution to the field.


Original manuscripts must be electronically submitted in a document attached to a formally sent e-mail to the Editors. Text in “ODT”, “SXW”, “DOC” or “RTF” file formats are preferred. Authors are asked to use A4 page size with 2 cm margins, Times New Roman 11 font and 1.5 lines as paragraph spacing. Figures may have high quality to allow electronic (“PDF”) viewing with enough details.

During the publication process, authors might be asked to change some formatting or submit equations, tables or pictures separately, if necessary.


Submitted files must not exceed 2 MB in total to allow e-mailing. If high quality images are to be included in the article and that excessively increases the size of the file, authors may send them separately to the Editors who will create a draft version of fair quality to be sent to the Reviewers. However, we strongly recommend sending the complete manuscript in a single file, with Figures and Tables inserted in the correct place. Please, be aware that simply pasting figures in some text editors will create unnecessarily large files. Paste them properly to avoid this (using the “paste special” utilities). Full quality pictures will be included, though, in the article when editing the final (corrected) version.


Manuscripts not formatted according to these Instructions for Authors will be immediately returned to the authors. Please, see one of our published articles or contact the Editors to eliminate any doubts.


Submit, along with the manuscript, the names and e-mail addresses of 3 or more potential Reviewers (Referees) who cannot belong to the same institution and may have no recent collaboration links with the authors. All manuscript must be sent by e-mail to the following electronic address: panamjas (at) gmail.com.


Manuscripts arrangement:


Authors are responsible for the content of submitted manuscripts, which have to be written in English. Non-English speakers must submit the manuscript to a native speaker or professional translator prior submission to Pan-American Journal of Aquatic Sciences.


Sentences must not start with an abbreviation. Acronyms must be written in full on their first occurrence and SI units should be used. Scientific names should be italicized (not underlined) and not abbreviated in legends of Figures and Tables. 


1) Research articles:


Title: concise and informative. The higher taxa containing the taxa dealt with in the paper should be indicated in parentheses: e.g. A taxonomic revision of the genus Atlantoraja (Elasmobranchii, Arynchobatidae).


Running headline: a short running headline of no more than 45 characters (including spaces) must be also provided.


Author(s): first names, middle names/initials, last names; postal addresses and e-mail addresses (Telephone/Fax number is not required). When authors belong to different institutions, an Arabic superscript number must be added and their addresses detailed below. Only the e-mail of the corresponding author must be indicated immediately after the postal address as in “… Rio de Janeiro, Brazil. E-mail: author@webmail.org”. Do not add all authors’ e-mails. Also, information on the professional or academic status (professor, PhD., student, trainee, etc.) must be avoided.


Abstract plus one Resumen (Spanish) or Resumo (Portuguese): It must concisely outline the scope of the manuscript (no more than 200 words for Research articles or three lines for Scientific notes), informing the main findings and conclusions without methodologies or discussions. Any new names or new combinations proposed in the paper should be mentioned. The second language abstract must include the title of the article in the corresponding language.


Key Words: up to five, that do not appear in the title, in English and in the language of the second abstract. Do not insert a full stop after the last key word.


Following sections should include: Introduction, Materials and Methods, Results, Discussion, Acknowledgments* (optional and brief) and References (please, see format below), as usual. Sections names must appear in low case and bold font and centered. Sub-section titles must appear also in low case and bold font aligned to the left.


*Acknowledgments: identify individuals by first initial and full surname (do not list professional titles), and institutions. Author may include collecting permits acknowledgments and any additional information concerning research grants, etc. If used, voucher-specimens must be identified with catalog number and name of the institution.


Tables: Should be numbered consecutively in Roman numerals and embedded in the manuscript as text, not pasted as a figure. If sent in a separate file (ex. in a spreadsheet file) consider that either the length or the width must fit an A4 page with 2 cm margins. Avoid abbreviations, except in the case of units. Each table must have its own title on the top, formatted in Times New Roman 10 font. In the text, tables should be referred as Table I, Tables II and III, Tables II-V, etc. The font in the tables as well as inside the figures must be Times New Roman, as for the text.


Figures: all figures must be embedded in the text. Please choose high resolution pictures. Prefer figures with the following extensions: jpg, tiff, png, bmp, gif. Other formats may be accepted after consulting the Editorial Board. Please, try not to exceed 1 MB per file in the initial submission. High quality color or black and white photographs, or computer-generated figures (e.g. maps) are acceptable. After the article's acceptance authors may be asked to send original, higher resolution figures. Figures should be referred to in the text as Figure 1, Figures 1 and 2, Figures 1-4, Figure 2a, (Fig. 1), (Fig. 1a), (Figs. 1-4), (Figs. 1a-1d), etc. Always use bar scales to indicate the size of photographed items. The legends must be concise but informative, formatted in Times New Roman 10 font. The species name must not be abbreviated in the legends.


Formulas: may be written in a single line even if they require special fonts (Symbol, Courier New or Wingdings), or may be part of the text. Ex: H2O, y=a+xb, etc. We recommend the use of an appropriate equation editor for better results.


Citations: Author citations in the text must follow the pattern: Garcia et al. (2004) or (Garcia et al. 2004), (Loebmann & Vieira 2006), Velasco et al. (2007), Oddone (2005). When referring to several publications in a row they must be cited in chronological order; e.g. (Bertalanffy 1938, Kinas 2000, Christensen & Walters 2004). Two or more publications by the same author must be cited as (Walters 2003, 2007) or (Bakun 2009a,b).

Personal communication of unpublished data must be accompanied by the person’s full name and professional address as a foot note.


References: see format examples below (please note spaces, bold, italic, commas and full stop usage). Grey literature must be avoided (e.g. symposium abstracts, unpublished institutional reports and monographs). If included (for example, being the cited reference the only publication of a particular subject), theses must include the full name of the institution, along with its city and country. See examples below.


Note that a space must be added between authors (and eventually editors) initials, as follows: Compagno, L. J. V. instead of Compagno, L.J.V. Moreover, authors’ initials must always follow the surname and not the opposite, for instance: Compagno, L. J. V & Vooren, C. M. instead of Compagno, L. J. V. & C. M. Vooren.
