Integrated system of taxonomic information


August 13, 2022

The Integrated Taxonomic Information System (ITIS) is a joint project of several government agencies created to provide a consistent and reliable source of taxonomy information for biological species. In 1996, ITIS was originally formed as an interagency group within the US federal government, involving agencies such as the Department of Commerce and the Smithsonian Institution. Now ITIS has become an international body, with the participation of governmental organizations of Canada and Mexico. ITIS' primary focus is on North American species, but many classified groups exist outside of North America, and ITIS continues to collaborate with other international agencies to ensure global coverage. ITIS provides automated access to databases of scientific and common names of species and other taxa. As of December 2006, the system contained more than 525,000 scientific names, synonyms, and colloquial names of terrestrial, marine, and freshwater taxa from all biological kingdoms (in this system: animals, plants, fungi, protozoa, and prokaryotes). Although the system focuses on North American species, it also includes many species not found in North America, particularly among birds, fish, amphibians, mammals, many reptiles, and several groups of invertebrates. ITIS links each scientific name to a stable and unique TSN taxonomic sequence number, a "common identifier" for accessing information on such phenomena as pathogenic species, endangered amphibians, migratory birds, fisheries, pollinators, agricultural parasites and emerging diseases. The system presents names in a standard classification that includes the author's name, date, distribution information, and bibliographic information about the title. In addition, colloquial names are available in the ITIS system in all major official languages ​​of the Americas, i.e. English, French, Spanish, and Portuguese). ITIS and its international partner, Species 2000, collaborate on the annual publication of the Catalog of Living Nature, a table and index of species from around the world. The goal of the Wildlife Catalog is to complete the classification of 1.8 million species by 2011. Of the nearly 424,000 scientific names (December 2006) in the database, approx�
