To earn authorship on a scholarly publication, a person should have contributed directly to the work in a meaningful and substantive way.

All collaborators in a project should evaluate their own and each other's roles and contributions to determine if and where they should be included in the list of authors. This assessment should take into account each contributor's role. 

Authorship requires direct contribution to each of the following aspects:

1. planning and executing some aspect of the study (conception, design, execution, analysis, interpretation) that led to the manuscript

2. writing of the draft or substantive editing and revising of the scholarly content

3. reading and approval of the finalized manuscript, at least of the aspects relevant to their roles and contributions

Please use the most current guidelines for inclusive attribution of authorship, such as guidelines developed by the British Ecological Society.
