You are invited to submit full papers for consideration in a special issue of the Philippine Journal of Systematic Biology

All submitted papers will be evaluated by the editors of the PJSB and will be subjected to peer-review prior to acceptance. Deadline is on June 30, 2019.

SUBMISSION GUIDELINES

The manuscript for submission should adhere with the PJSB Author Guidelines v2024 and should be accompanied by the fully accomplished PJSB Submission Form (i.e., cover letter is not anymore required).

Manuscripts must be submitted to our official email account (pjsb.submissions@gmail.com). Manuscripts not adhering to the guidelines will be returned to the author.

Focus and Scope

The Philippine Journal of Systematic Biology (PJSB; Print ISSN: 1908-6865; Online ISSN: 2508-0342) is an annual, peer-reviewed indexed journal in English that publishes high quality reports of original research and reviews in the fields of taxonomy, phylogeny, systematics, ecology, and conservation biology. It is indexed in Scopus, ASEAN Citation Index (ACI), and the Clarivate Analytics Master Journal List (formerly a subsidiary of Thomson Reuters, including ISI-Web of Science) under Zoological Record, BIOSIS Previews, and Biological Abstracts. Additionally, the PJSB is a recognized journal of the Philippine Commission on Higher Education (CHED) under CHED CMO 50 series of 2017. Moreover, the PJSB is now a member of the Committee on Publication Ethics (COPE).

 The PJSB is the official publication of the Association of Systematic Biologists of the Philippines (ASBP; SEC Registration: Association of Philippine Taxonomists, Inc.). The organization financially supports the journal and all its endeavors. The journal aims primarily to build up quality information on animal, plant and microbial diversity in the Philippines. Articles dealing with original research or reviews in zoological, botanical or microbial systematics, as well as ecology and conservation biology are welcome.

The PJSB strongly adheres to research and publication ethics. All submitted manuscripts are reviewed by at least two qualified referees. Submitted manuscripts should not have been published elsewhere or should have been submitted for review or publication simultaneous with the submission in the PJSB.

Submission Guidelines

The manuscript for submission should adhere with the PJSB Author Guidelines v2024 and should be accompanied by the fully accomplished PJSB Submission Form (The previous submission guidelines require a submission of a cover letter. This is now being replaced by the PJSB Submission Form). The form necessitates the corresponding author to confirm their agreement with the following:

  • All the authors listed in the manuscript are aware and have approved the manuscript for submission to the Philippine Journal of Systematic Biology.
  • At the time of submission to PJSB, the manuscript has not been submitted elsewhere for review and/or has not yet been published.
  • While the paper is being reviewed for publication in PJSB, the manuscript (or modification thereof) will not be submitted for publication in any other journal.
  • The authors have secured the right to reproduce any material that has been published already or where copyright is owned by another party.

Manuscripts must be submitted to our official email account (pjsb.submissions@gmail.com). Manuscripts not adhering to the guidelines will be returned to the author.

Peer Review Process

Manuscript submissions are pre-evaluated by two subject editors (members of the Editorial Board) who will serve as handling editors of a specific submission. Manuscripts may be rejected without peer review if the submitted manuscript is deemed to have limited scientific merit or does not fall within the scope of the journal.

Submissions that pass through the pre-evaluation process are processed for peer review, and sent to at least two independent reviewers by the Managing Editor and/or Assistant Managing Editor. The PJSB follows a “double-blind” review on all submitted manuscripts, in which the names of the authors and the identity of the reviewers are withheld. Peer reviewers are usually given one month to process their evaluation of a manuscript. Evaluation forms and other comments are forwarded to the authors and are given one to three weeks to revise and address the reviewers’ comments.

Once revisions are submitted, the subject editors will re-evaluate the manuscript based on the reviewers’ comments and decide whether the manuscript may be accepted at its current form. Further improvements may be suggested by the subject editors at this stage of the review process. If the subject editors find the manuscript already acceptable for publication, the manuscript will be forwarded to the Editor-in-Chief for final evaluation and acceptance.

Open Access Policy

This journal provides immediate open access to its content on the principle that making research freely available to the public supports a greater global exchange of knowledge. PJSB articles and other forms of publications published by the journal is protected under the Intellectual Property Code of the Philippines. Articles are distributed under the terms of the Creative Commons Attribution Non Commercial License (http://creativecommons.org/licenses/by-nc/3.0/), which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.

Ethical Responsibilities of Authors

Vouchering

Information on voucher and type specimens used in submitted manuscripts needs to be clearly indicated. The manuscript should include the locality of collection and related geographic entries, date of collection, name of the collector, repositories housing the type series, and their accession/specimen numbers. Though it is highly encouraged to disclose the complete information on the locality of collection sites, authors dealing with specimens which have a possibility to be exploited may not fully release the exact sampling location. Authors may instead indicate the general vicinity of the collection site and necessary collection permits.

For specimens collected in the Philippines, it is of utmost importance that holotypes of plants and animals be deposited in the Philippine National Museum of Natural History in accordance with the National Cultural Heritage Act of 2009 (R.A. 10066, Art. V, Sec. 17: “All types of specimen collected in the Philippine territory shall be deposited in the National Museum.”).

Collection Permits

The manuscript should include the biodiversity sampling permits (i.e., Gratuitous Permit) details such as the agency that released the permit (i.e., DENR, DA-BFAR, PCSD, BARMM-MENRE), year of release, and the permit number. Following the Wildlife Resources Conservation and Protection Act (R.A. 9147), it is assumed that the authors secured the corresponding free prior informed consent from the concerned localities included in their Gratuitous Permit. Additionally, whenever necessary, authors should declare the special collection permits from the National Commission on Indigenous Peoples (NCIP) and the Protected Area Management Board (PAMB).

Authors are required to clearly declare the biodiversity sampling permit details in the Acknowledgements section of the manuscript. Authors may opt to include additional details on permits in the Materials and Methods section.

Nomenclatural Registration and Genetic Data Submission

When erecting new taxon, authors shall be in charge of registering their taxon name on the appropriate biodiversity registry (e.g., Zoobank). The editorial team can provide guidance on this per request, but the authors shall perform the registration of their erected taxon. The authors must update the Managing Editor once the registration is completed and is successful, such that the issued registration ID will be encoded in the manuscript.

Authors shall be in charge of submitting their sequences to their chosen online repositories (i.e., GenBank, BOLD, ENA, DDBJ). The sequences must be submitted once the paper is accepted for publication to PJSB. The authors must update the Managing Editor once the submission of sequences is completed and is successful, such that the issued accession codes will be encoded in the manuscript. The authors are responsible for updating the databases to publish their sequences once their paper is out.

Use of AI
