To get information about biotic association and distribution records we used three sources:
- Encyclopedia of Life (EOL), provide information of biotic association from general sources like Wikipedia, NatureServe, but also more specific sources like North American Butterfly Knowledge Network.
- Biodiversity Heritage Library (BHL), provide digitial versions of legacy literature of biodiversity held in natural history and botanical libraries.
- Global Biodiversity Information Facility (GBIF), provide distribution records with different accuracy from country, province or ecoregion names, to point localities.
Due each data source have different structure and organization of the data, we developed a data extraction protocol specific for each source:
Protocol for data extraction from EOL
Protocol for data extraction from BHL
Protocol for data extraction form GBIF
