It has been requested that we relay the following statement:
REUSE OF IRMNG CONTENT:
The Open Tree Taxonomy does not reproduce its sources in their
entirety or in their original form of expression, but only uses
limited information expressed in them. See "Scientific names of
organisms: attribution, rights, and licensing" (http://dx.doi.org/10.1186/1756-0500-7-79)
regarding use of taxonomic information and attribution.
Where taxonomies conflict regarding taxon relationships, they are
resolved in favor of the higher priority taxonomy. The priority
ordering is as given above, with the following exceptions:
The non-Fungi content of Index Fungorum is separated from the Fungi
content and given a priority lower than NCBI and GBIF.
The non-Malacostraca, non-Ctenophora content of WoRMS is separated from the
Malacostraca and Ctenophora content and given a priority lower than NCBI but higher
