Project:New studies to add

Publications that describe symbiotic interactions that are not yet in the database.

Guidelines:

• Please list the DOI, or link to the publication full-text if a DOI is not available. A full citation is not necessary as the publication metadata can be retrieved from CrossRef with the DOI.
• If necessary, comment briefly on what information in the publication should be added to the database.
• Preprints can be listed here, but should only be added as database entries when a peer-reviewed version is published
• Remove entries from the list when the database has been updated.
