The list of authors should accurately reflect who carried out the research and who wrote the article. All multi-authored papers should include an ‘Authors’ Contributions’ section at the end of the paper.
The list of authors should correspond to the following criteria (based on ICMJE guidelines). Authors must meet all 4 of these conditions:
All authors must meet these criteria for authorship and, conversely, no-one should be omitted from the list if he/she meets these criteria.
For more guidance regarding authorship, including tips on how to manage author disputes and how to avoid any unethical authorship, please read our blog.
It is a condition of publication for the submitting author to provide an Open Researcher and Contributor ID (ORCID) via the online submission system. The benefits of registering an ORCID are outlined here. Provision of ORCIDs by co-authors is strongly encouraged, but not mandatory.
Contributors who do not meet all of the above criteria for authorship should not be listed as authors, but they should be acknowledged. Examples include general administrative support and writing assistance. Authors must confirm the contributor’s willingness to be acknowledged.
When deciding on authorship and other contributors please consider equity, diversity and inclusion. For example, if remote fieldwork is done with scientists on the ground or with the help of other locals these should be credited. Anyone who meets the criteria for authorship or acknowledgement must be included.
All authors, referees and editors must declare any conflicting or competing interests relating to a given article.
Competing interests are defined as those that, through their potential influence on behaviour or content or from perception of such potential influences, could undermine the objectivity, integrity or perceived value of publication.
They may include:

Funding received for the work described in the paper or for the publication itself, for all authors, must be declared within the publication. Examples of funding are:
