Figure 2. Frequency of Wikidata taxa linked to biodiversity databases.

Figure 2

This graph shows the proportion of the approximately 2.3 million Wikidata taxa with zero, one, two, etc. links to external biodiversity databases (NCBI, ITIS, GBIF, EOL, FishBase, Index Fungorum and iNaturalist). The majority of Wikidata taxa had at least two links. A little more than 15% of Wikidata taxa had no links to external biodiversity databases.
