TreeBASE is a repository of phylogenetic information, specifically user-submitted phylogenetic trees and the data used to generate them. TreeBASE accepts all kinds of phylogenetic data (e.g., trees of species, trees of populations, trees of genes) representing all biotic taxa. Data in TreeBASE are exposed to the public if they are used in a publication that is in press or published in a peer-reviewed scientific journal, book, conference proceedings, or thesis. Data used in publications that are in preparation or in review can be submitted to TreeBASE but will not be available to the public until they have passed peer review. Aside from the submitter, such data are only available to the publication editors or reviewers using a special access URL. TreeBASE is produced and governed by the The Phyloinformatics Research Foundation, Inc.
As of April 2014, TreeBASE contains data for 4,076 publications written by 8,777 different authors. These studies analyzed 8,233 matrices and resulted in 12,817 trees with 761,460 taxon labels that mapped to 104,593 distinct taxa.
