Introduction

Ecological Research (ER) is the official English-language peer-reviewed journal of the Ecological Society of Japan (ESJ) and celebrated its 30th anniversary in 2016. Submissions have greatly increased over that time and moved from print to electronic media. Along with changes by ER’s peers, i.e., other international ecological journals, ER has seen changes in its international position and in its expected role in the ESJ.

Asia includes a wide variety of climate zones, from tropical Indonesia to the Siberian tundra, which contain several heterogeneous ecosystems. However, despite the inclusion of China and India, which are, respectively, the most and second-most populous countries worldwide, the number of ecologists working in Asia has been limited and there are more opportunities for Asian studies. Thus, ER’s goal is to be the leading Asian ecological, evolutionary, and biodiversity journal to promote ecological research and outreach in Asia. To achieve this goal, the editorial office and board have improved ER’s editorial system, improved open access publication opportunities, and begun collaborations with other journals such as the Journal of Plant Research and Journal of Forest Research.

In looking to the future of ER on its 30th anniversary, we summarize a long-term direction of ER in supporting one of the objectives of the ESJ, i.e., “contributing to modern society via the progress and spread of ecology.” To assess the current status of ER worldwide and its recognition by ESJ members, we analyzed the journal’s publication records and conducted a web-based questionnaire from December 9, 2015 to January 15, 2016 (Supporting Information ESM 1, ESM 2), which we reported at the 63rd Annual Conference of the ESJ. The questionnaire was available only in Japanese and the respondents included non-ESJ members. The questionnaire results revealed that the efforts and strategies of the editorial office and board were not widely recognized. To share this information with more people in this Forum article, we introduce the development of ER to the present day, improvements to its editorial system and their outcomes, and strategies designed to achieve the goal. We need the involvement of all ESJ members to achieve ER’s goal. We hope that this article will encourage the participation of ESJ members in ER and thus promote ecology in Japan and Asia.

Development of ER to the present day

Until 1985, only one official journal was published by the ESJ, the Japanese Journal of Ecology, which presented articles in both Japanese and English. Authors who published in English may have hoped to improve the global dissemination of their research because English publications are read widely and promote valuable information exchanges. However, mixed-language journals would be less attractive than English-only journals for scientists internationally. Therefore, ER was launched in 1986 as the official English-language journal of the ESJ to improve the worldwide dissemination of ecological knowledge from Japan. Submissions and publications to ER have increased since 1986 and continue to increase (Fig. 1).

Most studies published in the early issues of ER were conducted in Japan by Japanese researchers (Fig. 2). Since then, the authorship and research fields have diversified and globalized dramatically. The proportion of Japanese first authors in published papers has decreased from about 80% in 1998 to about 50 and 30% in 2006 and 2015, respectively. This transition has been driven by increasing numbers of foreign authors (Fig. 3) and shows that ER has become an international journal recognized broadly by researchers internationally. In addition, the distribution of study sites has shifted from mainly Japanese sites in the 1980s to a more even global spread (Fig. 4). However, as the number of submissions has increased, the number of submissions that deviate from ER’s aim and scope has also increased, which increases the editorial burden.

Focal organisms have also changed. Initially, studies of plants and nutrient cycling were dominant. Studies focusing on plants accounted for more than half of published papers from 1986 to 1990 (Fig. 5). This high proportion of articles focusing on plants may be explained by the history of the ESJ, which was established in 1953 by the Plant Ecological Society (Bulletin of the Society of Plant Ecology) and the Phytoecological Society of Japan (Annals of Phytoecology) (The Ecological Society of Japan 2003). In addition, when ER was launched, population ecology was a big research focus in Japan. The Society of Population Ecology published Population Ecology (formerly Researches on Population Ecology, an English-only journal). By providing opportunities for studies of other ecological disciplines, such as production and physiological ecologies, ER allowed a differentiation in content between journals and the diversification of study materials in ER. Thus, the percentage of plant studies gradually decreased to about 40% in 2010–2015.

Such diversification and internationalization indicates that ER has developed into a comprehensive international ecological journal. However, some members of the ESJ retain impressions of an old stereotype of ER. For example, our questionnaire demonstrated that most people still see ER as a journal about plants (Fig. 6). This discrepancy between the current status of the journal and its stereotype may explain why submissions from Japan remain static. Indeed, the main reason for Japanese ecologists not to submit to ER is “no related articles” (Fig. 7). Thus, the journal’s new status must be promoted more broadly to encourage submissions from Japanese ecologists.

Improvements to ER’s editorial system and their outcomes

ER’s editorial system has been improved greatly in recent years (Fig. 8). Managing editors identify inappropriate submissions, which succeeded in reducing editorial costs. The managing editors rapidly assign each submitted manuscript to an appropriate Associate Editor-in-Chief (AEiC), whose expertise is close to the subject of the manuscript. The AEiC checks the manuscript contents and assigns suitable reviewers, either directly or indirectly through a handling editor. After review, the Editor-in-Chief makes the final decision. This process places a burden on the Editor-in-Chief; therefore, further improvement will be required in future, although the role of Editor-in-Chief is still needed to integrate the journal for ESJ. To improve the rapid handling of manuscripts and expand the expertise of the editorial board, the number of AEiCs, who are most closely involved with the manuscript submissions, increased from three in 2010 to 18 in 2016. The AEiCs can assign a handling editor to a manuscript when they already have several manuscripts to manage or when the expertise of the handling editor is more closely aligned with the manuscript than their own. These improvements have significantly improved the editorial process, especially the time from submission to peer review (Fig. 9). The editorial committee has appointed several members with expertise in new fields in ecology to increase the journal’s scope. In addition, in March 2016, the position of the Deputy Editor-in-Chief was created with a term of office that overlaps that of the Editor-in-Chief for 2 years (half of the total term), which allows a smooth transition of knowledge between incoming and departing Editors-in-Chief.

These improvements have contributed to shortening the time from submission to acceptance (and publication), even as the number of submissions increased (Fig. 9). Many Japanese editorial board members are aged in their 30 s or 40 s; therefore, they have great potential to contribute to the further development of ER. It is also notable that the editorial board includes many foreign scientists (37 people, 43% of total), who can promote ER in their own countries (Iwasa 2005). These editorial improvements provide ER with a good foundation for being a leading ecological, evolutionary, and biodiversity journal in Asia.

Copy editing by young ESJ members (promotion of future editor development) has also begun to improve the quality of accepted papers. Previously, submissions that did not follow the required format made the work of the editors and reviewers difficult. The copy editors now confirm the manuscript format, the integrity of the citations, and the accuracy of tables, figures, and captions. To help authors improve their figures, and tables, the copy editors created an online guide (see ESM 3) [The Ecological Society of Japan (n.d.)]. Nonnative English speakers are often supported by a qualified native-English-speaking editing service at the final stage of publication.

Strategies to achieve ER’s goal

The involvement of ESJ members is essential for the future development of ER. ESJ provided some awards, including the ESJ Award, Denzaburo Miyadi Award, Yasuyuki Oshima Award, and Nobuhiko Suzuki Award, to improve and encourage members. ESJ has long encouraged prizewinners to submit their manuscript to ER and some winners were published; therefore, the scope for papers published on ER was widened. This effort also contributed to attract young scientists, who widened their research interests after being inspired by ER articles. ER symposia and seminars provide good opportunities for members to collaborate in developing research. ER financially supports the participation of foreign scientists at the annual conference of the ESJ to facilitate research exchanges with other countries and consequently promote the internationalization of the ESJ. ER seminars are held as needed; e.g., seminars have been conducted on how to prevent research fraud or to explain the editorial process of scientific journals (Fig. 10) and seminars will be planned to promote contributions to ER and improve perceptions of the importance of ecology. Thus, your active participation is welcome. Historically, ESJ members might have viewed ER as being separate from the annual conference. However, if ER and the conference work together successfully, the development of ecological studies in Japan and Asia could be more successful. ER can also play a key role in the East Asian Federation of Ecological Societies (EAFES), because the journal has been recognized as an official publication of EAFES.

ER supports opportunities for interpersonal communications, which is very important in the context of collaborations between ER and conferences to develop ecological studies in Asia

In becoming a leading journal in Asia, it is important to establish ER’s position among scientific journals worldwide. To achieve this goal, ER created a new article category, Biodiversity in Asia, which caters to distinctive issues in Asia and accepts descriptive work related to the fundamental information of characteristic Asian biodiversity. As of November 2016, three papers had been already published in the Biodiversity in Asia category (Li et al. 2015; Choi 2016; Zhang et al. 2016). Furthermore, joint special issues with the Journal of Plant Research, “Long-term and multidisciplinary research of the forest carbon cycle at the Takayama site, Japan,” and the Journal of Forest Research, “Ecological aspects of management of overabundant deer populations,” have been published under a plan to publish distinctive content in ER and ensure its status as a comprehensive ecological journal. An ER-specific web page has been created to allow timely spread of information (http://www.esj.ne.jp/er/; Fig. 11).

As a means of exchanging information among members and world colleagues, ER encourages the publication of Forum articles such as this article. The Forum category is devoted to discussions of the future of ecology by ESJ-nominated authors. One Forum article (Kobori et al. 2016) is already highly downloaded and widely cited (5500 downloads and 10 citations, viewed April 6, 2017). The Forum category provides a key setting to promote ecology in Japan and Asia. In addition, to enhance the public availability of excellent ecological data sets through electronic archives, a special article type, Data paper, was launched in 2011 with the cooperation of the Japan Long-Term Ecological Research Network (http://www.jalter.org/). Many data descriptors of various data sets, mainly from Japan, have already been published. ER provides free access to basic information, abstracts, keywords, and data set URLs as an initiative to facilitate open science.

It is also worth noting how ER has adapted to the rapid changes in the publication of scientific journals. In the past decade, open access journals (e.g., PLoS ONE, Scientific Reports) have grown and are challenging the status of traditional journals. To remain competitive, ER has increased the proportion of open access articles published in the journal, which accounted for 16.8% of papers published in 2016. The ESJ has so far borne the open access costs for its ER award articles (e.g., Nakazawa 2016; Suzuki 2016) and for ER symposium papers (e.g., Papadopoulou and van Dam 2017). Further promotion of open access is under discussion with the journal’s publisher. The Editorial Committee also decided to increase the number of ER-awarded papers for ER in 2015 to recognize excellence in papers from various fields (Fujita and Koda 2015; Maldonado-López et al. 2015; Matsuura and Matsunaga 2015; Senga et al. 2015; Urakawa et al. 2015). Five or so papers are now selected annually for open access publication to reach a wider audience.

Submissions from ESJ members should be encouraged to balance the cost burden for the journal (i.e., editors, reviewers, and ESJ) and the beneficiaries (authors). In addition, fierce competition among scientific journals, especially North American and European journals, necessitates continuous efforts to hold or increase ER’s position. ER’s 2-year impact factor was generally unchanged during 2009–2015 (1.279–1.565). To improve its impact factor, ER should attract global audiences by inviting papers from leading researchers or publishing special issues focusing on timely and fascinating topics. The abovementioned strategies related to the journal’s broadening of authorship and its focus on Asia will help to strengthen its impact.

Such fierce competition among general ecological journals highlights the need for journals that publish research focusing on local issues. One possible explanation for ER’s steady impact factor is the high proportion of papers focused on locally important matters. Another explanation could be because of the high percentage of fundamental descriptive or case study researches in Asia, where the population of scientists is smaller and its history is shorter than that in North America and Europe (therefore, ecological knowledge is relatively scarce). Thus, it is also necessary to maintain ER as a reliable scientific journal that emphasizes the diversity of ecological research.
