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.
Stenus is a genus of semiaquatic rove beetles in the subfamily Steninae, and one of the largest genus in the kingdom Animalia, with some 2700 known species worldwide. They are predators of Collembola and other small arthropods. Adults have a protrusible labium with a sticky tip used in prey capture. To overcome the rapid escape of Collembola, the labium is protruded at high speed by hemolymph pressure, and immediately withdrawn, pulling the prey within the range of the mandibles. However, the labium tip does not easily stick to preys covered in scales or setae or that have a large body size. Stenus comma is more likely to catch such preys by lunging forward and grabbing them directly with its mandibles rather than using its labium. Stenus species are also known for "skimming" on the water surface using their pygidial gland secretions that act as a surfactant and rapidly propel the beetle fast forward, a phenomenon known as the Marangoni effect. Stenus comma has been seen to achieve a velocity of 0.75 m/s, and to cover a distance of up to 15 m if the secretion is continuous.
Psammobates is a genus of tortoise erected by Leopold Fitzinger in 1835. This genus contains three species, all of which are indigenous to southern Africa.
Cape Flats Sand Fynbos (CFSF), previously known as Sand Plain Fynbos, is a critically endangered vegetation type that occurs only within the city of Cape Town. Less than 1% of this unique lowland fynbos vegetation is conserved.
Species 2000 is a federation of database organizations around the world that compiles the Catalogue of Life, a comprehensive checklist of the world's species, in partnership with the Integrated Taxonomic Information System (ITIS). The creation of Species 2000 was initiated by Frank Bisby and colleagues at the University of Reading in the UK in 1997 and the Catalogue of Life was first published in 2001. While administrators and member organizations of Species 2000 are located around the world, the secretariat is located at the Naturalis Biodiversity Center in Leiden, Netherlands.
