Manuscripts have to be written in English and are submitted to a double-blind review process.
Submissions are accepted in the following research areas:
Agronomy and Forestry
Animal Sciences and Fisheries
Biodiversity and Conservation
Biotechnology
Chemistry and Pharmacology
Environmental Sciences
Food Sciences
Geosciences
Health Sciences
Human and Social Sciences
Materials Technology
GENERAL STYLE AND FORMAT
All manuscripts have to be submitted in English (both American and British English are accepted). As we use double-blind evaluation, all manuscripts have to be anonymized, i.e., all author information has to be submitted in a separate title-page file.
Manuscripts of all types have to be formatted as Office Word DOC/DOCX documents in A4 page size, with 3-cm margins all-round and continuous line numbering, written in Times Roman 12, with double line spacing throughout (including references and figure legends). Use single spacing for tables. Manuscript files should not exceed 2 MB.
Do not use one-sentence paragraphs. Avoid an excess of short paragraphs. Only one level of sub-titles is allowed within sections. Do not use sentences only to describe the content of tables or figures, as this information is redundant with figure legends and table captions.
Bibliographic citations are expected to be placed preferentially at the end of sentences, in parentheses. Use the format Smith (2007), (Smith 2007), Smith and Jones (2007), (Smith and Jones 2007), Smith et al. (2007), (Smith et al. 2007). Use the latter form for all references with more than three authors. List more than one citation in chronological order, and in alphabetical order for citations from the same year; for example: (Viana et al. 2001; Caldwell et al. 2007; Smith 2007; Benavides et al. 2017).
Cite figures and tables as (Figure 1) or (Table 1), etc. Cite figures and tables in the text in increasing numerical order. Place tables at the end of the manuscript. Figures have to be submitted separately (see below in Section Format).
Scientific names of species have to be written in italics and spelled out (e.g. Leporinus macrocephalus) in the title, and the first time they are cited in Abstract and Introduction. Use the abbreviated form (e.g. L. macrocephalus) in subsequent citations, except at the beginning of a sentence, when the name always has to be spelled out. Cite the author of the species (e.g. Leporinus macrocephalus Garavello and Britisk 1988) the first time it is cited after the Abstract.
Separate decimal fractions by a point, and separate numerals from measuring units by one space (e.g. 40.6 cm, 200.3 kcal), except for temperature units (e.g. 60°C, NOT 60 °C) and percentages (e.g. 5%, NOT 5 %). Use negative exponents instead of a slash (/) (e.g. cmol kg–1 instead of cmol/kg; m s–1, NOT m/s). Use space instead of point between symbols (e.g. m s–1, NOT m.s–1). Use kg instead of Kg and km instead of Km, etc. Formulas can be inserted in the text using the Office Word equation function tool.
Title page – Include in the title page file the title of the manuscript, the author names, authors’ institutional affiliations, e-mail of the corresponding author, the Acknowledgments section, and the Data Availability section (see below in Data Policy).
Write in capital letters the part of the surname that each author wants to be used in citations, e.g., if Maria Souza Pereira wants to be cited as Pereira MS, she should write her name as Maria Souza PEREIRA. If she wants to be cited as Souza-Pereira M, she should write her name as Maria SOUZA PEREIRA.
Write the authors' institutional affiliation in the language of the country of the institution. Names of institutions in countries that do not use the latin alphabet should be written in English. Write the affiliation beginning with the higher hierarchical level (e.g. university, research institute), followed by city, state and country. Street address is optional. If the author is affiliated to more than one institution, list each affiliation separately. When two or more authors share the same affiliation, list it only once. Check a recent issue of the journal for the format of authors names and institutions. Do not include titles (PhD, MSc, etc.) or other "mini CV" information in the address.
Original article – Manuscripts submitted as “original article” have to be based on original research and are limited to a total length of 7500 words (including title, abstract, references, figure legends and tables). Up to five tables and seven figures can be included (see below in Section Format).
Organize the manuscript in the following sequence: title in English, Abstract, Keywords, version in Portuguese OR Spanish of title, abstract and keywords, Introduction, Material and Methods, Results, Discussion, Conclusions, References, Figure Legends, Tables.
Abstract and Resumo/Resumen are limited to 250 words. Results and Discussion are strictly separated sections. Do not repeat results, nor cite figures or tables, in the Discussion section.
Short Communication - Manuscripts submitted as “short communication” have to be based on original research that consists of more simple reports or data of not enough complexity for submission as an original article. They are limited to a total length of 2500 words (including title, abstract, references, figure legends and tables). Up to two tables and three figures can be included (see below in Section Format).
Organize the manuscript in the following sequence: title in English, Abstract, Keywords, version in Portuguese OR Spanish of title, abstract and keywords, body of the text (no section titles), References, Figure Legends, Tables.
Abstract and Resumo/Resumen are limited to 150 words. Although no section titles are used, the text should follow a logical sequence of introduction, methodology, results, discussion and conclusive remarks.
No supplementary material is allowed for short communications.
Review - Manuscripts submitted as “review” have to be based on original propositions of literature and data compilation, including an analytical interpretation and discussion, not only a simple description of the reviewed material. They are limited to a total length of 7500 words (including title, abstract, references, figure legends and tables). Up to five tables and seven figures can be included (see below for figure submission).
Organize the manuscript in the following sequence: title in English, Abstract, Keywords, version in Portuguese OR Spanish of title, abstract and keywords, Introduction, Material and Methods, body of the text, References, Figure Legends, Tables. An introduction and methodological section are mandatory, but the organization of the text after that is at the discretion of the authors.
Abstract and Resumo/Resumen are limited to 250 words.
Supplementary material – The submission of supplementary material is allowed for original articles and reviews, to provide access to support material that is not essential to the study, but aids in the interpretation of the results. It may be in the form of tables, images or figures, or other support material, such as, for example, lists of collection material examined or questionaires applied in ethnological studies. These materials will be available only in the online version of the article. Refer to supplementary files in the text of the manuscript as (Supplementary Material, Table S1) or (Supplementary Material, Figure S1), or (Supplementary Material, Appendix S1), etc. For the review process, submit all supplementary material, including tables, figures plus figure legends in one DOC/DOCX file.
Audio and video files do not need to be referred to in the text as "Supplementary Material". It is sufficient to include the URL link of the source file. Access to these files has to be available for reviewers.
SECTION FORMAT
Abstract
The abstract should present an essential overview of the study that makes the gist of the study clear for readers that read only the abstract of the article. Make sure to present the justification and objective of the study, its geographical circumscription, general methodology used, main results, main discussion points and conclusion.
Keywords
Use up to six words or expressions as keywords. Do not use words that are already used in the title.
Introduction
This section should concentrate on introducing the specific subject of the study, avoiding information on the species, biome or research area that is unrelated to the specific objective of the study. The introduction should reflect the state of the art of the specific research topic, inform the knowledge gap addressed by the study, and make clear the interest of the study for the Amazon region. End the introduction with a paragraph stating the objectives of the study. State the working hypothesis of the study whenever pertinent.
Material and Methods
Description of study sites and general geographical and environmental contexts should be written for a non regional readership that is not familiarized with the region. Sampling design, experimental design, laboratory procedures and statistical analyses have to be described clearly and with sufficient detail as to be replicated by other researchers. Include informative location maps when required. Use past tense in this section.
Results
Provide here an objective report of observations, experiments, data analysis, etc. Always use past tense for reporting results. For the sake of transparency, report full test results, not only whether P is higher or lower than 0.05. Comments and interpretations belong to the Discussion. All tables and figures should be referred exclusively here. All samplings, experiments and analyses mentioned in Material and Methods have to be reported in the Results section and vice-versa.
Discussion
This section should not be a repetition of results followed by comments. The Discussion is not expected to contain any reporting of results, neither original nor repeated from the Results section. The Discussion is expected to have a content beyond the simple comparison with measures or test results obtained by other authors on the same subject. Tables and figures should not be referred here, unless it is very relevant for a point being highlighted. References should reflect the current state of the knowledge in the specific research area of the study. Include references preferentially at the end of the sentence, in parentheses.
Conclusions
Conclusions have to be written in one paragraph, and should present the answer to the question posed in the objectives, how the it fits into the body of knowledge on the subject, and how it informs future research.
Acknowledgments
This section is mandatory (to be placed in the title page) and should include all funding agencies of research grants and scholarships involved in the study, as well as institutional and individual support received by the authors. Names of institutions and agencies have to be spelled out and written in the original language of their home country (in English if the country of origin does not use the latin alphabet). If no external funding, nor specific funding from the home institution, was received whatsoever, authors are requested to state that the study was carried out without third-party funding and without specific institutional support.
References
References should be mainly of up-to-date published peer-reviewed articles and books. The reference to preprints is not allowed in the published article.

Figure legends
Legends of figures should include sufficient metadata to be self-explanatory. Identify the legend with the format: Figure 1.
Tables
Table captions should include sufficient metadata to be self-explanatory. Start the caption with the format: Table 1. Format tables with Office Word. Do not paste tables from other programs. Mark no vertical lines in tables. Use single spacing for table caption and content. When a table exceeds the size of the page, do NOT separate it in two independent tables.
Figures
Figures can be photographs, drawings or graphics. Submit figures exclusively as separate JPG or TIF files in high resolution, minimum 300 x 300 dpi, and maximum 6 MB individual file size. Photographs should be of high quality, sharp focus and adequate contrast. Do not use web posting resolution. Use at least resolution for printed documents. Figures should be formatted to fit within one column or two columns of the journal page format (check a recent issue for reference).
In graphs, mark the X and Y axes with a black solid line, and use inward-facing indentations for the scale-value positions only. Avoid the use of gridlines within the graph area. Place plot legends inside the graph area whenever possible. Both axes should have a title and scale values. Use a font size for axis titles and vales that is large enough to assure good visibility in one or two column width of the journal page. The meaning of symbols and acronyms used in figures must be defined in the figure legend. Do NOT use titles placed on top of the graph, nor outer encasing lines for the graph area.
In composite figures, label each panel with an uppercase letter (A, B, C, etc.).
Maps can have gridlines and have to include a scale bar.
Photographs, illustrations, maps and graphs can be submitted in color and will appear in color in the electronic version of the journal, but will appear in black and white in the printed version. If the authors wish that the figure appears in color in the printed version, the extra printing costs will be charged to the authors. When a color figure is submitted and intended only for the electronic version, please add "This figure is in color in the electronic version." to the figure legend.
Authors are kindly requested to give preference, whenever possible, to black and white graphs, which will be equaly readable in the electronic and printed versions.
For figures that have been previously published elsewhere, it has to be clearly stated in the figure legend that a permission for reproduction has been granted, along with the source of the figure. Authors may be asked at any time to provide the document that conceded the permission for reproduction. State the author of original drawings and photographs in the figure legend.
DATA POLICY
Nomenclature and units should follow internationally accepted rules and conventions. Use the metric system for measure units, following the International System of Units (SI) (https://www.nist.gov/publications/international-system-units-si-2019-edition).
