The Integrated Taxonomic Information System (ITIS) is an American partnership of federal agencies designed to provide consistent and reliable information on the taxonomy of biological species. ITIS was originally formed in 1996 as an interagency group within the US federal government, involving several US federal agencies, and has now become an international body, with Canadian and Mexican government agencies participating. The database draws from a large community of taxonomic experts. Primary content staff are housed at the Smithsonian National Museum of Natural History and IT services are provided by a US Geological Survey facility in Denver. The primary focus of ITIS is North American species, but many biological groups exist worldwide and ITIS collaborates with other agencies to increase its global coverage.
Lemna is a genus of free-floating aquatic plants referred to by the common name "duckweed". They are morphologically divergent members of the arum family Araceae. These rapidly growing plants have found uses as a model system for studies in community ecology, basic plant biology, ecotoxicology, and production of biopharmaceuticals, and as a source of animal feeds for agriculture and aquaculture. Currently, 14 species of Lemna are recognised.
Spirodela is a genus of aquatic plants, one of several genera containing plants commonly called duckweed. Spirodela species are members of the Araceae under the APG II system. They were formerly members of the Lemnaceae.
Azolla filiculoides is a species of Azolla, native to warm temperate and tropical regions of the Americas which was introduced to Europe, North and sub-Saharan Africa, China, Japan, New Zealand, Australia, the Caribbean and Hawaii.
The Ghana rufous-nosed rat, also known as the West African Oenomys, is a species of rodent in the family Muridae. It is found in Ivory Coast, Ghana, Guinea, Liberia, and Sierra Leone. Its natural habitats are subtropical or tropical seasonally wet or flooded lowland grassland and seasonally flooded agricultural land, it has also been observed in secondary high forest habitat.
Lemna minor, the common duckweed or lesser duckweed, is a species of aquatic freshwater plant in the subfamily Lemnoideae of the arum family Araceae. L. minor is used as animal fodder, bioremediator, for wastewater nutrient recovery, and other applications.
Lemna minuta is a species of duckweed known by the common name least duckweed. It is the smallest Lemna species. It is native to parts of the Americas, and naturalized in others; the exact native range is not known. It is found on other continents as a non-native introduction as well. The plant's distribution is ever-expanding; it has been spreading in Europe and it was described from Poland for the first time in 2007. In many areas it is a noxious weed, such as in Belgium.
A taxonomic database is a database created to hold information on biological taxa – for example groups of organisms organized by species name or other taxonomic identifier – for efficient data management and information retrieval. Taxonomic databases are routinely used for the automated construction of biological checklists such as floras and faunas, both for print publication and online; to underpin the operation of web-based species information systems; as a part of biological collection management ; as well as providing, in some cases, the taxon management component of broader science or biology information systems. They are also a fundamental contribution to the discipline of biodiversity informatics.
The Kimberley rock monitor is a medium-sized species of monitor lizard in the family Varanidae. The species is native to Northern Australia. Also known as Glauert's monitor or the Kakadu sand goanna, it belongs to the subgenus Odatria.
Spirodela polyrhiza is a species of duckweed known by the common names common duckmeat, greater duckweed, great duckmeat, common duckweed, and duckmeat. It can be found nearly worldwide in many types of freshwater habitat.
Symphyotrichum dumosum is a species of flowering plant of the family Asteraceae commonly known as rice button aster and bushy aster. It is native to much of eastern and central North America, as well as Haiti and Dominican Republic. It is a perennial, herbaceous plant that may reach a height of 1 meter.
The white sucker is a species of freshwater cypriniform fish inhabiting the upper Midwest and Northeast in North America, but it is also found as far south as Georgia and as far west as New Mexico. The fish is commonly known as a "sucker" due to its fleshy, papillose lips that suck up organic matter and aufwuchs from the bottom of rivers and streams.
Agalinis heterophylla is a species of flowering plant in the family Orobanchaceae known as prairie false foxglove. It is found in northern Mexico (Tamaulipas) and the southeastern and central United States.
Atriplex prostrata, called the spear-leaved orache, hastate orache, thin-leaf orache, triangle orache, and fat hen, is a widespread species of flowering plant in the saltbush genus Atriplex, native to Europe, Macaronesia, northern Africa, Ethiopia, the Middle East, western Siberia, and Central Asia, and introduced to temperate North America, South America, Australia, New Zealand, Korea, Japan, and Primorsky Krai in far eastern Russia. It is a facultative halophyte.
Carex pedunculata, the long-stalk sedge or longstalk sedge, is a species of flowering plant in the genus Carex, native to Canada and the central and eastern United States. Its seeds are dispersed by ants.
Vernonia fasciculata, the smooth ironweed or common ironweed, or prairie ironweed is a species of perennial plant in the family Asteraceae. It is native to Manitoba in Canada and the north-central U.S.A.
Cazuza's saki is a species of saki monkey, a type of New World monkey. It is endemic to northwestern Brazil.
Isabel's saki is a species of saki monkey, a type of New World monkey. It is endemic to a small portion of northern Peru.
Mittermeier's Tapajós saki is a disputed species of saki monkey, a type of New World monkey. It is endemic to west-central Brazil.
Solanum viride, the green nightshade, garland berry, cannibal's tomato, poroporo or boro dina, is a species of flowering plant in the family Solanaceae. It is native to the Cook Islands, Fiji, Marquesas Islands, Niue, Pitcairn Islands, Samoan Islands, Society Islands, Tokelau and Manihiki, Tonga, Tuamotus, and Tubuai Islands in the South Pacific. It has been introduced to Hawaii. In Fiji at the time of contact, human meat was cooked wrapped in its leaves, and a condiment for the meal was made from the fruit.
