ITIS (Integrated Taxonomic Information System)This portal collates authoritative taxonomic information on plants, animals, fungi, and microbes of North America and the world. It is a partnership of U.S., Canadian, and Mexican agencies (ITIS-North America); other organizations; and taxonomic specialists. Searching ITIS will provide links to information about species from multiple databases and collections worldwide. ITIS is also a partner of Species 2000 and the Global Biodiversity Information Facility (GBIF). The ITIS and Species 2000 Catalogue of Life (CoL) partnership provides the taxonomic backbone to the Encyclopedia of Life (EOL).
