The editorial team, reviewers, and authors share responsibility for ensuring that published research meets accepted standards of scientific rigor, ethical conduct, transparency, and reproducibility.

1. Authorship and Contributorship
Authorship must accurately reflect individuals who made substantial intellectual contributions to the study. All authors must approve the submitted and final versions of the manuscript and agree to be accountable for the integrity of the work.
During submission, authors must confirm that the manuscript is original, is not under consideration elsewhere, complies with all applicable ethical requirements, and has been approved by all co-authors.
Nauplius adopts the CRediT (Contributor Roles Taxonomy), and each author's contribution must be specified in the manuscript under the "Additional Information and Declarations" section. Requests for changes in authorship after submission are strongly discouraged and will only be considered under exceptional circumstances with appropriate justification and approval from all authors.

2. Complaints and Appeals
Nauplius supports a fair, transparent, and impartial editorial process.
Authors, reviewers, and readers may submit complaints concerning the editorial process, publication ethics, or editorial conduct, or appeal editorial decisions by providing a clear justification and supporting evidence.
Complaints and appeals should be submitted to the Editorial Office. They will be treated confidentially and evaluated by the Editor-in-Chief or, when appropriate, by another member of the Editorial Board who is free from conflicts of interest. Editorial decisions regarding complaints and appeals follow COPE recommendations, and the final decision will be communicated to the corresponding party.

3. Research Misconduct
Nauplius takes allegations of research or publication misconduct seriously. Any concern regarding the integrity of a submitted or published article will be assessed carefully, fairly, and confidentially, following the recommendations of COPE and the SciELO Program.
Research misconduct includes, but is not limited to, plagiarism, self-plagiarism, duplicate publication, data fabrication, data falsification, image manipulation, citation manipulation, peer-review manipulation, inappropriate authorship practices, undisclosed conflicts of interest, and any other practice that compromises the integrity of the scientific record.
Whenever allegations of misconduct arise before or after publication, the journal will investigate the case according to the COPE guidelines. Authors may be requested to provide original data, documentation, permits, or additional information necessary for the investigation. When appropriate, the authors' institutions or funding agencies may also be contacted.
Depending on the outcome of the investigation, the journal may reject the manuscript, publish corrections, issue expressions of concern, retract the article, or adopt any other measures considered appropriate to preserve the integrity of the scholarly record

4. Conflicts of Interest
All authors, reviewers, and editors are expected to disclose any financial, institutional, personal, academic, political, or commercial relationships that could influence—or reasonably be perceived to influence—the editorial process or the interpretation of the research.
Authors must disclose any conflicts of interest during submission and include a declaration in the published manuscript. Editors and reviewers who identify a potential conflict must decline participation in the editorial process whenever impartiality cannot be guaranteed.

Readers may communicate potential errors, request clarifications, or submit comments regarding published articles. When appropriate, the journal may publish Letters to the Editor, Corrections, Expressions of Concern, or Retractions to maintain the accuracy and integrity of the scientific record.

9. Corrections and Retractions
When errors or misconduct affecting the reliability of a published article are identified, Nauplius will act promptly to preserve the integrity of the scholarly record.
Corrections (Errata) are issued for errors that do not invalidate the main conclusions of the article but require clarification or amendment.
Retractions are published when reliable evidence demonstrates that the findings are no longer trustworthy because of honest errors or research or publication misconduct.
All corrections, expressions of concern, and retractions follow the recommendations of COPE and the SciELO Guidelines for the registration and publication of corrections and retractions. Retraction notices remain permanently linked to the original article and clearly explain the reasons for the editorial action.

10. Integrity of the Scholarly Record
Preserving the integrity of scientific literature is a central responsibility of Nauplius. Submitted manuscripts are routinely screened for textual similarity using iThenticate, and any concerns regarding plagiarism, duplicate publication, data manipulation, inappropriate image processing, citation manipulation, authorship disputes, or other forms of misconduct are investigated according to established editorial procedures and internationally accepted ethical guidelines. When necessary, the journal will publish corrections, expressions of concern, or retractions to ensure that the published record remains accurate and trustworthy.
Any allegation involving plagiarism, duplicate publication, citation manipulation, fabricated or falsified data, image manipulation, inappropriate use of artificial intelligence technologies, authorship disputes, peer-review manipulation, or undisclosed conflicts of interest will be evaluated according to COPE recommendations and the SciELO Guidelines.
Nauplius supports correcting the scientific record whenever necessary and ensuring that editorial decisions are based exclusively on scientific merit, ethical standards, and transparency.

Nauplius is committed to maintaining the integrity of the scholarly record, but in the event that an article, after being published, needs to be modified, Nauplius will promote the modification through a correction or retraction.
A decision on how to correct the article will depend on the nature of the error;
A correction (erratum) will be used when some errors or omissions that may exert influence in the interpretation of some contend, but does not substantially alter the reliability or the scholarly integrity of the article is discovered by the author and/or editor;

The registration and publication of a correction follow the procedures recommended by SciELO Brazil in the Guidelines for registry and publication of errata and be in accordance with the practices suggested by the Committee on Publication Ethics – COPE.
A retraction will be used when fundamental errors, resulting either from unintentional mistakes (e.g., in analysis or methods) or in cases where there is clear evidence of research and/or publication misconduct that could unequivocally compromise the reliability and the scholarly integrity of the article;

Nauplius uses the Retraction Guidelines established by the Committee on Publication Ethics - COPE as a basis for evaluating misconduct cases;

Nauplius follows the procedures recommended by SciELO Brazil in the Guidelines for registry and publication of retraction;
The retraction note should provide transparency on which part(s) of the article are impacted by the error.

Authors have an obligation to correct mistakes once they discover a significant error or inaccuracy in their published article. The author(s) is/are requested to contact the journal and explain in what sense the error is impacting the article;

Nauplius follows the requirements of Article 8 of the International Code of Zoological Nomenclature and all articles published have fixed content from the moment of their publication date. An eventual change to an article will only be permitted through the publication of an erratum.

Nauplius also allows debate post publication through letters to the Editor-in-Chief. 

Any conflict of interest of any of a personal, commercial, political, academic, or financial nature must be declared by the authors upon submission of the manuscript and at the end of the manuscript in the “Additional information and declarations” section. Editors and reviewers must also disclose any potential conflicts that may influence the evaluation of the manuscript. In such cases, they should promptly inform the editorial office, and the assignment will be reassessed to ensure an unbiased review process.

Only original, genuine data must be submitted; any kind of plagiarism or citation manipulation is strongly discouraged and will not be accepted. Nauplius currently makes use of iThenticate software to check for plagiarism;

Nauplius does not permit the use of Generative AI or AI-assisted technologies– such as ChatGPT or similar services– for authors or during peer review to protect authors' rights and ensure research confidentiality of submitted research. We are actively evaluating compliant AI tools that comply with ethical and legal standards and may revise this policy in the future as technologies and guidelines evolve.

The edorial team of Nauplius, as well as the authors who publish in the journal, must always observe the Sex and Gender Equity in Research (SAGER).

• Avoid using the name of new taxa in the title.
• The International Code of Zoological Nomenclature requires that publication of new taxa in electronic-only journals must be registered in the Official Register of Zoological Nomenclature, with Zoobank as its online version. The Nauplius editorial team will obtain the Zoobank registration number (LSID) of all publications and nomenclatural acts once the manuscript is accepted. The authors should not provide this registration in advance.
• Telegraphic style is mandatory for descriptions and diagnoses.
• Accession numbers of publicly available genetic sequence databases (e.g., BOLD, DDBJ, ENA, GenBank) must be included for DNA results such that the raw data can be accessed and compared against the presented data.
• Tissued specimens should be vouchered and their institutional catalog number provided in association with their respective database accession numbers in the “Material examined” list or in a summary table.

B. Reviews
Nauplius welcomes scientific investigations that reappraise relevant studies on specific topics of Carcinology on the basis of a critical and comprehensive review of the literature. Manuscripts of Review articles should be prepared following the same recommendations as regular articles, but the divisions of the main text may be more flexible at the discretion of the author.

C. Short Communications
Nauplius accepts short notes when they present information that cannot be incorporated into a regular paper. Manuscripts should be prepared following the same recommendations as regular articles; however:

• The manuscript text should be limited to approximately eight pages written in Times New Roman, size 12pt, and double space formatting, since this will not normally exceed six final printed pages in length and should contain only one figure and/or table.
• The sequence of contents should be: Title, Full Names of Author(s), Affiliation(s) and email(s), Running Head, Abstract, Keywords, Main text (without delimitation of sections), Acknowledgements, Additional information and declarations, References, and Caption for Table and Figure (if any).

When submitting a manuscript, please state in the cover letter that (1) the manuscript has been submitted solely to this journal and is not published, in press, or being considered for publication elsewhere; (2) that all research meets the ethical guidelines, including adherence to the legal requirements of the country where the study was conducted; and (3) that the manuscript is approved by all authors.

Figures, Tables, Graphs, Maps, and Supplementary Material

• Figure and table files must be uploaded separately on respective forms onto the ScholarOne Manuscripts system (https://mc04.manuscriptcentral.com/nau-scielo).
• All table and figure captions should be self-explanatory, and be able to stand alone from the text.
• Figures should be submitted as separate files (TIF, JPG) and should be of high quality. For black and white drawing/line artwork, these should be 600 dpi resolution at final size. Half-tone grayscale artwork should be 600 dpi at final size. Color half-tone images should be submitted as 300 dpi. Maximum figure width should be 2000 pixels.
• Nauplius may request replacement of the figures that do not meet these quality standards.
• Tables should be self-explanatory and submitted as separate files (.doc or .docx). Vertical lines and Roman numerals in the tables should be avoided, and horizontal lines used minimally.
• All figures and tables should be referenced consecutively in the main text, using uppercase for the first letter and Arabic numerals (e.g., Fig. 1; Fig. 1A, B; Figs. 1–4; Tab. 1; Tabs. 1, 2; Tabs. 1–3). However, when using the words “Figure(s)” and “Table(s)” at the beginning of a paragraph or a sentence, do not abbreviate them.
• List the figure and table captions in order on separate pages after the “References” section in the main text.
• It is the responsibility of the author(s) to obtain permission from the copyright holder to reproduce figures or tables originally published elsewhere.
• Nauplius encourages the use of color in graphics and figures.
• The approximate positions of figures and tables will be indicated in the text file by the Editorial team.
• Nauplius recommends that authors pay special attention so that, in all graphics, the legends of the axes have standardized lettering.
• Binomial names should be written in full in the captions of figures and tables, but authorities need not be used if this information has already been provided in the main text. Use italics for the binomial names either in the captions or in the illustration itself.
• Tables and figures should be kept to a minimum; authors are strongly encouraged to include large tables as Supplementary Material.
• Nauplius recommends that map(s) should indicate (a) the north direction; (b) a scale bar; and (c) latitude and longitude at least in one of the margins.
• Supplementary Material (e.g., large tables, spreadsheets, figures, PDF files, audio and/or video files, software codes, external databases, etc.) may accompany the manuscript for publication along with the article.

• Nauplius primarily follows the APA structure for citations and references, with some modifications as specified in this page and in the "Organization of Manuscripts and Technical Standards" document.
• All publications referred to in the text must be listed alphabetically by the authors’ surname in the “References” section. See the guidelines of manuscript preparation for further instructions.
• Authors must make sure that all references cited in the text and eventually in tables are congruent with those listed in the “References” section.
• In the body of the text cite as follow (depending on the context):

• One author: Silva (2006) or (Silva, 2006)
• Two authors: Silva and Santos (2006) or (Silva and Santos, 2006)
• Three or more authors:  Silva et al. (2006) or (Silva et al., 2006)
• Citation of more than one reference must be arranged chronologically (not alphabetically) and separated by semi-colons: (Silva, 2005a; 2005b; 2006; Silva and Santos, 2006; Albano, 2008).
• Do not use "&", "op. cit." or "apud".

• Use "in press" only when formal acceptance has been granted and a DOI has already been assigned.
• Citation of theses, dissertations, technical reports, and abstracts presented at meetings is emphatically discouraged. However, if essential, indicate if the document is available online and the URL to access it should be provided, as well as the date of access; a statement of [Unpublished] must be added at the end of the citation.
• Authors of quoted unpublished material (e.g., manuscript under review, internal report, and certain conference abstracts) should be cited only if strictly necessary. Author (initials and surname) of quoted unpublished material should be inserted in the text and designated as "unpublished data/unpubl. data" or "personal communication/pers. comm." (e.g., G.A.S. Melo, pers. comm.), but should be omitted from the “References” section.
• Name of periodicals should be given in full and italic, followed by a comma and the volume number. The issue number (if available) should be in parentheses just after the volume number (no space separating them). Use en-dash (−) for page ranges.
• Add the Digital Object Identifier - DOI for all works (including older publications, if any) that have a DOI; if an online work has both a DOI and a URL, include only the DOI.
• DOI should be included in the format: https://doi.org/xxxxx
• Papers published in an online-only journal should show the volume and the e-location (see examples below).
• In cases of discrepancy with the year of publication of some articles, see further instructions in the guidelines of manuscript preparation with detailed instructions in addition to the examples below.
• In the “References” section, the name of authors should be written with the surname followed by a space (no comma) and the initials (no full stop). References with two names must be linked by “and” (not “&”) as well as between the penultimate and the last names of references with three or more authors; use semicolon to separate the other names.
