Message from the Editor in Chief

We take up a responsibility for the academic society

    Nowadays, we often need to pay expensive page charges/open-access fees to publish our works as most of the journals are now run by business publishers. Is it possible there are quality assured, peer-reviewed and open-access SCI scientific journals, in which colleagues can publish their research achievement free? We, Biodiversity Research Center, Academia Sinica, Taiwan, attempts to take up this responsibility. We run Zoological Studies, to provide a free SCI open-access publication platform for colleagues to share out their research achievements.
    Publish articles free of page charges does not mean Zoological Studies is lack of good quality. All the accepted articles passed a formal review system. Impact factors is an indication for the article citations in a journals and has implications for journal quality. However, article citations can be also affected by the ways of marketing methods for journals in commercial publishers. We are trying hard to maintain a good impact factor for Zoological Studies. All articles are 1) formally applied for a DOI number and being open-access in the web, 2) listed and housed in PubMed database and 3) promoted in our twitters and facebook. We are not under any umbrella of commercial publishers. All the editors and reviewers are volunteers for the academics. We hope you can support us to submit your quality works to Zoological Studies, and upload your published articles in Research Gate to enhance citations as well.

Prof. Benny K.K. Chan
