TraitBank is a searchable, comprehensive, open digital repository for organism traits, measurements, interactions and other facts for all taxa across the tree of life.
Whether you are fact-finding or conducting analyses, we invite you to explore this new dimension to the Encyclopedia of Life. Please share your feedback regarding any aspect of TraitBank.
How it Works
TraitBank is integrated into the fabric of EOL, and leverages its existing infrastructure for names, content organization, curation roles and search. Data records are aggregated from databases, literature tables, and other sources.
A sample of records appears on the Overview tab for each organism's EOL page, and all records available for each organism appear on a new Data tab on each EOL taxon page.
All data are subject to curation by EOL curators. For each data record, TraitBank displays all of the related information we receive from the data provider, including its provenance, attribute definitions, measurement methods, and related data elements from the same set.
Using the data search tool you can find and download all data TraitBank holds for each attribute of interest. You can search and filter by specific values and by taxon, and can sort the results.
How to Contribute or Re-use TraitBank Data
If you have numerical data, controlled vocabulary terms for a large number of organisms, or ecological interaction data, please contact us about adding these data to TraitBank.
TraitBank records are derived from data sets that are released under an Attribution Creative Commons License or that are without any copyright restrictions. You can download data through the search interface. A read API and other ways to access the data are in development.If you use any of these data, please be sure to cite the sources. Full credits are provided in the Data tabs of EOL taxon pages and in the download files.
How to Become a TraitBank Research Collaborator & Sponsor
The EOL team has the capacity to support a limited number of research collaborations each year. These collaborations make it possible for the EOL team to help researchers make the best use of existing TraitBank capabilities and provide expertise for data mobilization, extraction and analysis efforts. EOL is also interested in opportunities to extend TraitBank's capabilities to support project-specific requirements. To learn more contact the EOL Secretariat.
We invite biodiversity researchers to take advantage of the significant investments and expertise behind TraitBank as part of their grants and other sponsored projects. To learn more contact the EOL Secretariat.
Substantial financial support for the first release of TraitBank comes from the Alfred P. Sloan Foundation, with additional support from the John D. and Catherine T. MacArthur Foundation, the institutional partners of the Encyclopedia of Life, and the global community of EOL users. We also thank EOL's Science Advisors and beta testers for their able assistance.
