Nematropica Guidelines for Authors

Printer Friendly Version | Spanish Version

Nematropica (ISSN 2220-5608) is an international scientific journal of tropical and subtropical nematology. Beginning in 2011 with Volume 41 Nematropica will be exclusively an on-line journal available via the ONTA website and


Contributions describing nematological research in temperate regions will be considered if they are of general interest. Articles on plant-parasitic, entomophilic, and free-living nematodes are equally welcome. Research notes, review articles, and Symposium Proceedings will be considered. Manuscripts accepted for publication must be scientifically sound, suitable for the audience of the journal, and prepared according to the guidelines provided below. Manuscripts must not have been published previously or simultaneously submitted elsewhere. A checklist is provided to assist in manuscript preparation. Please complete the Author Checklist and submit it with your manuscript. The names of two colleagues who have reviewed the manuscript must be included on the checklist. Manuscripts should be written in English, Spanish, French, or Portuguese, and submitted to the Editor-in-Chief. All articles in Nematropica include abstracts in English and Spanish (or the language in which the article was written). Editors will translate abstracts for authors if necessary. Manuscripts may be submitted electronically or by mail. Portions of articles in Nematropica may be reprinted without permission, provided that Nematropica is cited as the original source.

Submission Procedure

The Editor-in-Chief of Nematropica for 2017-2019 is Dr. Brent Sipes (   Manuscripts should be e-mailed to Cathy Howard, Assistant to the Editor-in-Chief at  She will acknowledge receipt and assign your manuscript a number.

Accompanying E-mail message should include the following information:

  • Title of article
  • Type of article (Research Report, Research Note, Review Article, Symposium Proceeding)
  • Name, affiliation, email and mailing addresses (including postal code), telephone and fax numbers of corresponding author
  • List of attached documents
  • A statement that all authors have reviewed the manuscript and approved its submission to Nematropica.
  • Completed Author’s Checklist for submitted manuscripts (see below).
  • A statement indicating that at least one of the authors is a current member of ONTA.  We no longer accept manuscripts from non-members.

Manuscript Preparation

Microsoft Word for Windows is the preferred file format for text. However, Rich Text Format (.rtf), Word for Macintosh, and WordPerfect for Windows formats are acceptable. Manuscript pages should be numbered in the upper right corner and lines of text on each page should be numbered.

Each table should be placed on a separate page following the references. Prepare tables in the table format with one data field per cell. Captions for figures should be provided in a list at the end of the text, following the references and tables. Double-space the entire document (including tables), and use a 12 point font. Do not right justify and do not hyphenate at the ends of lines. Scientific binomials and other words, symbols, or punctuation marks that are italicized in Nematropica should be either italicized or underlined in the manuscript. The two styles are not mixed. Bold type is only used in the Title. A running head of no more than 60 characters is included under the author affiliations.

Illustration files should not be merged, imbedded, or linked to the text file, but kept completely separate; figure numbers placed within the body of the text will be used to determine the placement of illustrations. Appropriate formats for figures are JPEG or TIFF with at least 300 dpi. Manuscripts that do not conform to Nematropica format may be returned to the author to correct serious format difficulties prior to the review process.

Review Process

All manuscripts submitted to Nematropica are subjected to peer-review. Upon submission, the manuscript to be reviewed is distributed to 2 qualified reviewers. Authors will receive an acknowledgement email with a reference number for the manuscript. Authors should refer to this number in all correspondence with the Editor. Reviewers have 3 weeks to review the submission and to recommend to the Editor-in-Chief acceptance (generally with revision) or rejection.

Authors who wish to publish in Nematropica must be willing to act on the recommendations of reviewers and editors. Suggested revisions that substantially change the author’s intent or appear to be in error may be rebutted with a documented explanation in an e-mail to the Editor-in-Chief when the revised manuscript is returned.

If the manuscript is accepted with revision, the Editor-in-Chief returns the manuscript to the corresponding author. Authors should then make any suggested changes in the article and return it to the Editor-in-Chief by email fully formatted with italics, subscripts, etc. within 6 weeks. The author must also return marked manuscripts and reviewer’s comments. In an email message, the author should explain how criticisms were dealt with and why criticisms may not have been accepted. The revised article will be reviewed by the Editor-in-Chief and, if judged acceptable for publication, will be checked for formatting and final submission for layout of pdf. Unless authors have permission from the Editor-in-Chief for a brief delay in revision, a manuscript requiring more than 6 weeks for revision should be sent to the Editor-in-Chief as a new submission. Authors will receive an acceptance email. There are no page charges for members of ONTA.

Types of Articles

Research Reports

Research Reports are full length articles. They should describe original work that represents a significant advance in the understanding of a particular issue or concept or that leads to practical solutions to existing problems. The work described must not have been published before (except in the form of an abstract or as part of a published lecture, review, or thesis). Data reported in Nematropica must be from scientifically valid, replicated plots or observations and subjected to appropriate statistical analysis.

Research Notes

Research Notes are short articles that report new findings relevant to readers of Nematropica. Notes are shorter than a Research Report and include an Abstract and Resumen but do not include section headings (Materials and Methods, Results, and Discussion). Abstracts for Notes are limited to 200 words. Notes provide an outlet for science-based findings that are important to crop advisers, growers, diagnosticians, researchers, regulatory officials, and other practitioners. Notes are intended to stand alone and should not include preliminary reports of work that will later be presented in full-length papers. Notes are not abstracts and must not duplicate abstracts published or submitted elsewhere.

Review Articles

Reviews are articles that summarize and analyze a topic of importance to tropical and subtropical nematology for those who are not specialists in the topic area of the review. Readers should be able to learn what is known and what questions remain unresolved about the subject. Reviews should include an introduction to the problem or issue including why the topic is of interest and a discussion of the issues or new information as it relates to tropical or subtropical nematology. The body of the review may be subdivided using headings that describe the major ideas being discussed. Reviews should cite suitable references to document statements that are not considered general knowledge and may also provide a list of printed and/or electronic resources for further information.


Symposium Proceedings


Proceedings from a Symposium presented at an annual ONTA meeting may be published in Nematropica. However, it is important that one member of the symposium should act as overall organizer and ensure that: (1) every speaker agrees to submit a manuscript within 3 months of the symposium; (2) revisions are made in a timely manner following peer-review; (3) the organizer prepares an introduction to the symposium that sets the context for readers so they understand why the symposium is important: and (4) the organizer will be responsible for enforcing agreed-upon deadlines.


Manuscript Formatting Guide:

Research Reports should contain the following sections and appear as illustrated below. See the description of different types of publications provided above for formatting variation for Notes and Review articles.






Name(s) of the author(s) should appear under the title, centered on the page, with a designation* for the corresponding author.


Institutional addresses for all authors should be left justified. The corresponding author should include additional information including postal code, telephone and fax numbers, and an e-mail address.


Running Head: should be 60 characters or less and follow author affiliations



Author1, A. A., B. B. Author2, and C. C. Author3. 2011. Title of Manuscript in 12 pt. font

double spaced. Nematropica 41:00-00.


The abstract should provide a summary of the main points of the article and why the

research results should be viewed as important.


Key Words: Key words should follow the abstract and be in alphabetical order.



Author1, A. A., B. B. Author2, and C. C. Author3. 2011. Title of Manuscript in Spanish/Portuguese/French in 12 pt. font double spaced. Nematropica 41:00-00.


Abstract written in English will be translated into Spanish by the Editors if necessary.

The Editors will also translate abstracts into English for manuscripts written in Spanish, French, or Portuguese if necessary.



Briefly describe the problem and the reasons for conducting the research. Authors should establish the context of their research at the beginning of the article and then present objectives of the research.



Materials and methods should describe the research methods used in enough detail that readers could duplicate the experiments or directly find the specific methods necessary for duplicating experiments in the referenced literature. Experimental designs should be fully described and the statistical analysis procedures used should be specified. Subheadings for Materials and Methods, Results, and Discussion sections should be in upper and lower case letters and italicized.



Experimental results should be clearly described.



The discussion should relate work presented in the manuscript to other published material, and address the strengths and weaknesses of the presented research. Major conclusions should be supported by the results from experiments.



Authors should use this space to acknowledge people making significant contribution to the research presented, funding sources, etc.
