History of the Revista de Biología Tropical



Manuscripts that meet our scope and format indications are sent to three external anonymous reviewers who act as referees and include an ethics assessment in their opinion (we apply plagiarism software to all manuscripts). For a more objective evaluation, both reviewers and authors ignore each other identities (double blind). The evaluation forms are public (here). The second draft is corrected by our staff and returned with instructions to prepare the final version for publication.

The first decision of acceptance or rejection rests with the Editor, who is based on the opinions and scores provided by referees. Authors can appeal Editor’s decisions to the Editorial Board and the board’s decision is final. Board meeting proceedings are stored in the University Archive as public documents.

The journal publishes nearly 130 articles per year, not including the occasional supplements. The rejection rate is 28 % ad portas and 38 % after peer review (2018 data).

Considering both boards, 82 % of members are external to the publishing institution and foreign authors and institutions represent 78 % of articles in normal issues and 12 % of supplements (2018 data). All processing is documented in OJS.




URL interoperability protocol:



Copyright is openly shared by the authors and the journal; contents can be reproduced if the source and copyright are acknowledged, according to our CC BY Open Access license. Self-storage in preprint servers and repositories is allowed for all versions. We publish machine-readable versions as soon as available. We encourage authors to publish raw data and data logs in public repositories and to include the links from the first draft on, so that reviewers and readers can consult them at any time. Blogs with comments and a Forum section that allows reply articles are available to readers in our website.

The journal is financed by public funds via the Universidad de Costa Rica, and editorial independence and ethical compliance are guaranteed by SIEDIN norms (



The journal publishes only original work that makes a clear and strong contribution of new information in its field. When authors submit a manuscript they legally imply that they followed all pertinent legislation and ethical principles (including informed consent and proper treatment of nature according to UNESCO Recommendation on Science and Scientific Researchers; Committee on Publication Ethics and Helsinki Ethical Norms,; that all coauthors participated in the main aspects of research and agree to publication; and that the study is original; scientifically valid; has not been published before, and was not sent simultaneously to another journal. Board and staff members can publish in the journal but are excluded from all decisions regarding their manuscripts.

Authors, reviewers, board members and staff must report conflicts of interest as soon as they arise. Any cases of error, citation manipulation, piracy, plagiarism, duplicate submission, republication, fabrication or falsification of data, and financial conflict, must be informed to the Editorial Board, which will investigate them even if the report is from anonymous sources. Articles found in fault can be rejected, retracted or be added errata.



Regular issues are published four times per year, on March 1st, June 1st, September 1st and December 1st. Single subject supplements and other special publications are published when available.

The digital preservation of all journal issues, manuscripts, reviews and administrative documentation is responsibility of the Journal Portal of the University of Costa Rica, official administrator of the Open Journal System. Internally, to guarantee security and independence from local failures and influences, our policy is to transparently back-up all additional administrative documentation via commercial servers located in a different country.

According to Dr. Ettore de Girolami, in September of 1952, he proposed the creation of a scientific journal sponsored by the University of Costa Rica to Dr. Alfonso Trejos, Director of the Clinical Laboratory, San Juan de Dios Hospital. According to Dr. Rodrigo Zeledón, the idea was “already in the air” among a small group of microbiologists and physicians. In any case, Dr. Trejos took the idea with enthusiasm and began planning the journal.

By that time, Dr. Rodrigo Facio, with whom Dr. Trejos and Dr. de Girolami had a good relationship, was elected University President. They knew that Dr. Facio had other priorities in his new administrative position, yet they submitted their idea to him and to the University Council. The establishment of a journal would bring the opportunity to disseminate, in Costa Rica and foreign countries, the scientific goals and products of the institution and would also enrich the university library thanks to journal exchange, quite common at the time.

In October of the same year, in an informal meeting, Dr. Facio, recommended them how to proceed with the administrative paperwork, prior to the presentation of the project to the University Council. In December, the formal proposal was ready, and the Council approved it on January 5th, 1953. Few days later, founder members met several times to discuss details, such as journal name, size, issues published every year, type of paper, shape and color of the front cover and how many copies would be printed in each edition. All were difficult decisions that, at the end, were properly solved.

Considering that most articles were expected to be regional, the word “tropical” should be part of the journal's name. The University of Costa Rica had only four faculties at the time: Pharmacy, Odontology, Sciences, and Agronomy, in consequence, the appropriate word was “biology”. To choose the first word of the name, a list of known journals was consulted: Acta, Anales, Boletin, Publicaciones, Gaceta, Revista, Prensa, etc.

On February 9th, 1953, founders met with the deans of the four faculties and made a final pronouncement: the name of the journal would be "Revista de Biología Tropical".

Most steps were followed as expected, with the exception of some problems in the university’s printing office, that was not ready to start publishing the new journal. To solve this, the University President and the Treasurer, Mr. Abel Méndez, authorized the Board to hire an external company that could print the Revista. The company, FALCO, offered the best options in quality and price, and had a linotypist with experience in scientific terminology.

On July 15, 1953, the first issue of the Revista de Biología Tropical was out of the printer and ready to be distributed.

Since then, the journal has been an important motivation for young scientific minds who work in tropical countries, and find in Revista de Biología Tropical a good medium to express their ideas.
