Our editorial board and editors evaluate that each submitted manuscript meets our scope and format indications, and is original and interesting; we provide a first decision within seven working days. Editorial decisions are stored in the Archive of the University of Costa Rica as public documents.

Manuscripts at this editorial stage are sent to two or three external reviewers. Both reviewers and authors are unaware each other identities (double-blind).

The acceptance or rejection decision of each manuscript rests with the Editors, who act based on the opinions and scores provided by referees. The manuscript can be rejected or sent back to authors for either major or minor improvements.

The second draft is accepted if the authors properly take into account reviews and editorial indications.  Some manuscripts required a second peer review round. The editorial staff verify that corrections were done, and in the proofreading process, the manuscript is returned with instructions to prepare the final version for publication.

Authors can appeal the Editors’ decisions to the Editorial Board once and the Board’s decision is final.

Rapid decision and publication (7 days for first decision, 4-8 months from submission to publication).


The evaluation forms for reviewers, which include our criteria, are public (here).

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: ActaAnalesBoletinPublicacionesGacetaRevistaPrensa, 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.

Summarized from a Spanish account written by Ettore De Girolami in 1988, and complemented with Rodrigo Zeledón’s recollection (summary by J. Monge-Nájera).
