Tropics is an international, peer-reviewed, and Open Access journal published twice yearly with one volume comprising two issues by the Japan Society of Tropical Ecology (JASTE). Tropics publishes manuscripts covering all aspects of ecology and ecology-related science about tropical regions. Manuscripts are limited to three types: original articles, reviews, and field notes. Each manuscript must be a report of original research that has not been previously published in whole or in part, and is not under consideration for publication in any other journal except for a preprint server. Manuscripts should be written in English. Tropics has been listed in Emerging Sources Citation Index (ESCI) since 2017 and received its first journal impact factor 0.7 in 2023.


The journal is open to the results of original research, experimental or descriptive, and to significant reviews of aspects of the ecology and ecology-related science about tropical regions. Its aim is not only to act as a valued means of communication between Japanese ecologists and other field scientists, but also to stimulate the research activities of ecologists and scientists of tropical regions. Those interested in contributing to Tropics are highly encouraged to submit their work.  


Special issues of monographs or reviews may be published on occasion by decision of the editorial board.


Manuscripts published on a preprint server can be submitted to Tropics under the following conditions. The manuscript must be the original version of the manuscript describing primary research. The revised manuscript, following reviewers' comments, and the manuscript accepted to Tropics should not be posted to the preprint server. When the manuscript is accepted and published in Tropics, the authors should update the information on the preprint server to make a link to the manuscript in Tropics on J-Stage.

Full text PDF files of recent volumes are available at J-STAGE.

2. Publication ethics and malpractice statement

Research misconducts and malpractice harm individual and society.  Although researchers may get temporal benefits from their publication by misconducts and malpractices, such publication retard the advance of science and the authors also suffer disadvantages much larger than the temporal benefits once the misconducts revealed. The editors of Tropics work hard to avoid publishing research papers from misconducts and malpractices in Tropics. In addition to those efforts, we need cooperation and understanding from the authors to avoid misconducts and malpractices. So, the editorial board requests all authors to take “3. Authors’ responsibility” listed below, before submitting their manuscript to Tropics. 

3. Author's responsibilities

The authors should confirm that the study was carried out within appropriate ethical frameworks of their society and also scientific fields. To avoid publishing research results by malpractices*, the editorial board requests all authors to confirm following points before submitting their manuscript to Tropics. 


・The study has not been published and is not currently under review in other journals.

・All authors have contributed to the study and read the submitted version of the manuscript.

・All authors have committed for avoiding research misconduct such as fabrication, falsification, plagiarism as well as multiple submission of the same research results and inappropriate authorship.

・All authors have agreed to submit the manuscript to Tropics as well as to participate the peer review process of Tropics.

・All authors have declared any possible conflict of interests or they have confirmed that there is no conflict of interests.

・All authors have agreed that the editorial board may request authors to show evidences they followed necessary ethical framework and they will respond the request.

・All authors have agreed that they and the editorial board are obliged to provide retractions or correction of mistakes before and after publication of their manuscript.

・All authors have agreed that they transfer the copyright of their articles to JASTE effective when the articles are accepted for publication and JASTE publishes the articles under the Creative Commons CC BY 4.0 International license.
