Project:New studies to add

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

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.

Remove entries from the list when the database has been updated.
