Genus is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.
Charales is an order of freshwater green algae in the division Charophyta, class Charophyceae, commonly known as stoneworts. Depending on the treatment of the genus Nitellopsis, living (extant) species are placed into either one family (Characeae) or two. Further families are used for fossil members of the order. Linnaeus established the genus Chara in 1753.
Ebbe Schmidt Nielsen was a Danish entomologist influential in systematics and Lepidoptera research, and an early proponent of biodiversity informatics. The journal Invertebrate Systematics was established with significant contributions from Nielsen, and he assisted in the founding of the Global Biodiversity Information Facility (GBIF). Nielsen wrote several books, published over eighty scientific papers, and was highly regarded within the scientific community. Following his death, the GBIF organised the Ebbe Nielsen Prize in his memory, awarded annually to promising researchers in the field of biodiversity informatics. The moth Pollanisus nielseni is named after Nielsen.
Biodiversity informatics is the application of informatics techniques to biodiversity information, such as taxonomy, biogeography or ecology. It is defined as the application of Information technology technologies to management, algorithmic exploration, analysis and interpretation of primary data regarding life, particularly at the species level organization. Modern computer techniques can yield new ways to view and analyze existing information, as well as predict future situations. Biodiversity informatics is a term that was only coined around 1992 but with rapidly increasing data sets has become useful in numerous studies and applications, such as the construction of taxonomic databases or geographic information systems. Biodiversity informatics contrasts with "bioinformatics", which is often used synonymously with the computerized handling of data in the specialized area of molecular biology.
The Catalogue of Life is an online database that provides an index of known species of animals, plants, fungi, and microorganisms. It was created in 2001 as a partnership between the global Species 2000 and the American Integrated Taxonomic Information System. The Catalogue is used by research scientists, citizen scientists, educators, and policy makers. The Catalogue is also used by the Biodiversity Heritage Library, the Barcode of Life Data System, Encyclopedia of Life, and the Global Biodiversity Information Facility. The Catalogue currently compiles data from 165 peer-reviewed taxonomic databases that are maintained by specialist institutions around the world. As of September 2022, the COL Checklist lists 2,067,951 of the world's 2.2m extant species known to taxonomists on the planet at present time.
The Tetrasporales are a formerly recognized order of green algae, specifically the Chlorophyceae, now included in Chlamydomonadales. AlgaeBase places Tetraspora and Tetrasporaceae in Chlamydomonadales.
Hormotila is a genus of green algae in the family Chaetophoraceae.
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive list of names of marine organisms.
Iguanodectes is a genus of freshwater fish found in tropical South America, with eight currently described species. They are all small tetras, none longer than 5 inches, and often have attractive silvery or striped scales, which makes them a target for the ornamental fish industry. Alongside the genus Piabucus, it is in the subfamily Iguanodectinae, which in turn is in the family Iguanodectidae. The genus Bryconops, which is also in Iguanodectidae, makes up a sister clade to Iguanodectinae.
The Flanders Marine Institute provides a focal point for marine scientific research in Flanders, northern Belgium.
Hirudinidae is a family of leeches belonging to the order Arhynchobdellida.
Cloacina is a genus of parasitic nematodes in the family Chabertiidae. Species are parasites of marsupials in Australia.
× Oncostele, abbreviated Ons., is a hybrid genus of orchids, used for greges containing at least one ancestor species from the genera Oncidium (Onc.) and Rhynchostele (Rst.). The nothogenus was defined in 2003 by J. M. H. Shaw.
Nomenclator Zoologicus is one of the major compendia in the field of zoological nomenclature, compiled by Sheffield Airey Neave and his successors and published in 9 volumes over the period 1939–1994, under the auspices of the Zoological Society of London; a tenth, electronic-only volume was also produced before the project ceased. It contains over 340,000 published name instances with their authorities and details of their original publication, certain nomenclatural notes and cross references, and an indication of the taxonomic group to which each is assigned. An electronic (digitised) version of volumes 1-10 was released online by the uBio project, based at the Marine Biological Laboratory, Woods Hole, in 2004–2005.
The Ocean Biodiversity Information System (OBIS), formerly Ocean Biogeographic Information System, is a web-based access point to information about the distribution and abundance of living species in the ocean. It was developed as the information management component of the ten year Census of Marine Life (CoML) (2001-2010), but is not limited to CoML-derived data, and aims to provide an integrated view of all marine biodiversity data that may be made available to it on an open access basis by respective data custodians. According to its web site as at July 2018, OBIS "is a global open-access data and information clearing-house on marine biodiversity for science, conservation and sustainable development." 8 specific objectives are listed in the OBIS site, of which the leading item is to "Provide [the] world's largest scientific knowledge base on the diversity, distribution and abundance of all marine organisms in an integrated and standardized format".
Compsosaurus is an extinct genus of phytosaur, a crocodile-like reptile that lived during the Triassic. Its fossils have been found in North Carolina. The type species, Compsosaurus priscus, was named by American paleontologist Joseph Leidy in 1856, although other sources say 1857. Compsosaurus may have been the same animal as the related Belodon.
Anthony J. J. ("Tony") Rees is a British-born software developer, data manager and biologist resident in Australia since 1986, and previously a data manager with CSIRO Marine and Atmospheric Research. He is responsible for developing a number of software systems currently used in science data management, including c-squares, Taxamatch, and IRMNG, the Interim Register of Marine and Nonmarine Genera. He has also been closely involved with the development of other biodiversity informatics initiatives including the Ocean Biogeographic Information System (OBIS), AquaMaps, and the iPlant Taxonomic Name Resolution Service (TNRS).
Haementeria is a genus of leeches in the family Glossiphoniidae. The genus was described in 1849 by Filippo De Filippi.
Laxta friedmani, the flat cockroach, is a species of Blaberidae occurring in Australia. The habitat is under loose back of eucalyptus trees, and fallen leaf litter on the ground. Length is up to 25 mm, a flattened creature, resembling a trilobite, sometimes found in small groups. Females are wingless, adult males with wings.
Pentacheles is a genus of crustaceans of the class Malacostraca.
