Ethical responsibilities of authors of 
Journal of Nanjing Forestry University (Natural Sciences Edition )(JNFU)

JNFU are members of the Committee on Publication Ethics (COPE), abide by its Code of Conduct, and aim to adhere to its Best Practice Guidelines.
Authors, editors, and reviewers are expected to be aware of, and comply with, best practice in publication ethics.

Publication Ethics for Authors
Authors should refrain from misrepresenting research results which could damage the trust in the journal and ultimately the entire scientific endeavour. Maintaining integrity of the research and its presentation can be achieved by following the rules of good scientific practice.

[plagiarism]
Plagiarism is not acceptable in NJFU submissions. Plagiarized content will not be considered for publication. If plagiarism is identified, we will follow COPE guidelines.
Plagiarism includes, but is not limited to:
• Directly copying text from other sources without attribution
• Copying ideas, images, or data from other sources without attribution
• Reusing text from your own previous publications without attribution or agreement of the editor
o Exception: Reusing text from the Methods section in the author’s previous publications, with attribution to the source, is acceptable.
• Using an idea from another source with slightly modified language without attribution

[Concurrent publication]

•The manuscript has not been submitted to more than one journal for simultaneous consideration.
• The manuscript has not been published previously (partly or in full), unless the new work concerns an expansion of previous work (please provide transparency on the re-use of material to avoid the hint of text-recycling (“self-plagiarism”)).
• A single study is not split up into several parts to increase the quantity of submissions and submitted to various journals or to one journal over time (e.g. “salami-publishing”).
• No data have been fabricated or manipulated (including images) to support your conclusions
• No data, text, or theories by others are presented as if they were the authors own (“plagiarism”). Proper acknowledgements to other works must be given (this includes material that is closely copied (near verbatim), summarized and/or paraphrased), quotation marks are used for verbatim copying of material, and permissions are secured for material that is copyrighted.

[Authorship]
• Consent to submit has been received from all co-authors and responsible authorities at the institute/organization where the work has been carried out beforethe work is submitted.
• Authors whose names appear on the submission have contributed sufficiently to the scientific work and therefore share collective responsibility and accountability for the results.
In addition:
• Changes of authorship or in the order of authors are not accepted after acceptance of a manuscript.• Requests to add or delete authors at revision stage or after publication is a serious matter, and may be considered only after receipt of written approval from all authors and detailed explanation about the role/deletion of the new/deleted author. The decision on accepting the change rests with the Editor-in-Chief of the journal.• Upon request authors should be prepared to send relevant documentation or data in order to verify the validity of the results. This could be in the form of raw data, samples, records, etc.
[Originality]
•The authors should ensure that they have written entirely original works. The manuscripts submitted to JNFU are solely the authors’ own work. Information from published articles must always be cited explicitly. The manuscripts must not contain any results that have been, or will be reported in other medium in any form. [Reporting standards]•Authors reporting results of orginalresrarch should present an accurate account of the work performed as well as an objective discussion of its significance. Underlying data should be represented accurately in the manuscript. A paper should contain sufficient detail and references to permit others to replicate the work.

If there is a suspicion of misconduct, the journal will carry out an investigation following the COPE guidelines. If, after investigation, the allegation seems to raise valid concerns, the accused author will be contacted and given an opportunity to address the issue. If misconduct has been proven, this may result in the Editor-in-Chief’s implementation of the following measures, including, but not limited to:
- If the article is still under consideration, it may be rejected and returned to the author.
- If the article has already been published online, depending on the nature and severity of the infraction, either an erratum will be placed with the article or in severe cases complete retraction of the article will occur. The reason must be given in the published erratum or retraction note. The author’s institution may be informed.

[Submission declaration and verification]
Submission of an article implies that the work described has not been published previously (except in the form of an abstract or as part of a published lecture or academic thesis or as an electronic preprint), that it is not under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere in the same form, in English or in any other language, including electronically without the written consent of the copyright-holder. To verify originality, your article may be checked by the originality detection service CrossCheck http://www.elsevier.com/editors/plagdetect.
