Phalangodidae
The Phalangodidae are a family of harvestmen with about 30 genera and more than 100 described species, distributed in the Holarctic region. It is not to be confused with the harvestman family Phalangiidae, which is in the suborder Eupnoi. Name The name of the type genus ''Phalangodes'' is derived from Ancient Greek ('), a line of soldiers in formation. This probably refers to the rows of pedipalpal spines. Description Body length ranges from less than 1 mm to about . The pedipalps are armed with large spines. While some species have legs eight times the body length, others have shorter legs around twice the body length. Most species are yellowish to orange brown. Troglobitic (cave-dwelling) species are depigmented. Distribution More than two-thirds of the species occur in the western Nearctic, especially in California] with about 50 species in four endemism, endemic genera. About 10 species are known from the eastern Nearctic. Few occur in the Palearctic, with one spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) 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. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Family (taxonomy)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opinion ...

Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Integrated Taxonomic Information System
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. Reference database ITIS provides an automated reference database of scientific and common names for species. As of May 2016, it contains over 839,000 scientific nam ...

Catalogue Of Life
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 fro165 peer-reviewed taxonomic databasesthat are maintained by specialist institutions around the world. , the COL Checklist lists 2,067,951 of the world's 2.2m extant species known to taxonomists on the planet at present time. Structure The Catalogue of Life employs a simple data structure to provide information on synonymy, grouping within a taxonomic hierarchy, common names, distribution and ecological environment. I ...

Global Biodiversity Information Facility
The Global Biodiversity Information Facility (GBIF) is an international organisation that focuses on making scientific data on biodiversity available via the Internet using web services. The data are provided by many institutions from around the world; GBIF's information architecture makes these data accessible and searchable through a single portal. Data available through the GBIF portal are primarily distribution data on plants, animals, fungi, and microbes for the world, and scientific names data. The mission of the GBIF is to facilitate free and open access to biodiversity data worldwide to underpin sustainable development. Priorities, with an emphasis on promoting participation and working through partners, include mobilising biodiversity data, developing protocols and standards to ensure scientific integrity and interoperability, building an informatics architecture to allow the interlinking of diverse data types from disparate sources, promoting capacity building and ca ...

National Museum Of Brazil
The National Museum of Brazil ( pt, Museu Nacional) is the oldest scientific institution of Brazil. It is located in the city of Rio de Janeiro, where it is installed in the Paço de São Cristóvão (Saint Christopher's Palace), which is inside the Quinta da Boa Vista. The main building was originally the residence of the House of Braganza, Portuguese royal family between 1808 and 1821 and was later used to house the Brazilian imperial family between 1822 and 1889. After the monarchy was deposed, it hosted the Republican Constituent Assembly from 1889 to 1891 before being assigned to the use of the museum in 1892. The building was listed as Brazilian National Heritage in 1938 and was largely destroyed by a fire in 2018. Founded by João VI of Portugal, King João VI of Portugal, Brazil and the Algarves on 6 June 1818, under the name of "Royal Museum", the institution was initially housed at the Campo de Santana (park), Campo de Santana park, where it exhibited the collections ...

Harvestmen
The Opiliones (formerly Phalangida) are an Order (biology), order of arachnids Common name, colloquially known as harvestmen, harvesters, harvest spiders, or daddy longlegs. , over 6,650 species of harvestmen have been discovered worldwide, although the total number of extant taxon, extant species may exceed 10,000. The order Opiliones includes five suborders: Cyphophthalmi, Eupnoi, Dyspnoi, Laniatores, and Tetrophthalmi, which were named in 2014. Representatives of each extant suborder can be found on all continents except Antarctica. Well-preserved fossils have been found in the 400-million-year-old Rhynie cherts of Scotland, and 305-million-year-old rocks in France. These fossils look surprisingly modern, indicating that their basic body shape developed very early on, and, at least in some taxa, has changed little since that time. Their Phylogenetics, phylogenetic position within the Arachnida is disputed; their closest relatives may be the mites (Acari) or the Novogenuata ( ...
