We now have an R package BioTIMEr to help with spatial gridding, sample-based rarefaction, and diversity metric calculation.
Guidelines
We ask you to provide proper attribution. Cite our database as well as the relevant citations for the individual studies you use in any publication. Our citation and metadata tables will help with locating the right information about references and licences.
Whenever you download and use data from the BioTIME database, we ask that you respect the licences associated to the database and datasets. In the data download, you will find the licences for each study in the metadata table. We break down the core differences between these licence types below, but it is ultimately your responsibility to consult the actual licence. Violation of licence terms mean that BioTIME and/or the data contributors can revoke the freedom to use and share data.
How to cite BioTIME
You can cite our database in this style below or using the RIS file download if you use citation management software like Endnote, Zotero, Mendeley, etc.
