Species
In biology, a species is the basic unit of 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 produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, 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 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 specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woodlouse
A woodlouse (plural woodlice) is an isopod crustacean from the polyphyleticThe current consensus is that Oniscidea is actually triphyletic suborder Oniscidea within the order Isopoda. They get their name from often being found in old wood. The first woodlice were marine isopods which are presumed to have colonised land in the Carboniferous, though the oldest known fossils are from the Cretaceous period. They have many common names and although often referred to as terrestrial isopods, some species live semiterrestrially or have recolonised aquatic environments. Woodlice in the families Armadillidae, Armadillidiidae, Eubelidae, Tylidae and some other genera can roll up into a roughly spherical shape ( conglobate) as a defensive mechanism; others have partial rolling ability, but most cannot conglobate at all. Woodlice have a basic morphology of a segmented, dorso-ventrally flattened body with seven pairs of jointed legs, specialised appendages for respiration and like ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), 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 taxonomy (biology), 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 ...

Porcellio
''Porcellio'' is a genus of woodlice in the family Porcellionidae. These crustaceans are found essentially worldwide. A well-known species is the common rough woodlouse, '' Porcellio scaber''. Most of the hundreds of ''Porcellio'' species were described by 1950, and many were known by the end of the 19th century already. But occasionally, new species have been found even in recent times. Species There are approximately 191 species in the genus ''Porcellio'' : ''Porcellio cyclocephalus'' and ''P. notatus'' are fossil species from Baltic amber The Baltic region is home to the largest known deposit of amber, called Baltic amber or succinite. It was produced sometime during the Eocene epoch, but exactly when is controversial. It has been estimated that these forests created more than .... They are placed in the present genus for lack of a better alternative, but whether this is correct is doubtful as the original descriptions are very brief and hardly diagnostic. Refe ...

Family (biology)
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 opini ...

Porcellionidae
Porcellionidae is a terrestrial family of the order Isopoda. This family contains 530 species, found on every continent except Antarctica. The ventral plate of the thoracic exoskeleton flare out slightly over the legs. This "flare" is called the ''epimeron''. The uropods, antenna-like structures at the back of the specimen, are flattened out and spearlike, and extend beyond the last exoskeletal plate. Genera The family contains 19 genera, and two further genera (''Inchanga Inchanga is a village in KwaZulu-Natal, South Africa, approximately halfway between Durban and Pietermaritzburg. Schools Inchanga has several schools, including Rietvallei Combined School, Siphesihle High School, Inchanga Primary School In ...'' and '' Mahehia'') may be included. *'' Acaeroplastes'' Verhoeff, 1918 *'' Agabiformius'' Verhoeff, 1908 *'' Atlantidium'' Arcangeli, 1936 *'' Brevurus'' Schmalfuss, 1986 *'' Caeroplastes'' Verhoeff, 1918 *'' Congocellio'' Arcangeli, 1950 *'' Dorypoditius'' ...

Fauna Europaea
Fauna Europaea is a database of the scientific names and distribution of all living multicellular European land and fresh-water animals. It serves as a standard taxonomic source for animal taxonomy within the Pan-European Species directories Infrastructure (PESI). , Fauna Europaea reported that their database contained 235,708 taxon names and 173,654 species names. Its construction was initially funded by the European Council (2000–2004). The project was co-ordinated by the University of Amsterdam The University of Amsterdam (abbreviated as UvA, nl, Universiteit van Amsterdam) is a public research university located in Amsterdam, Netherlands. The UvA is one of two large, publicly funded research universities in the city, the other being ... which launched the first version in 2004, after which the database was transferred to the Natural History Museum Berlin in 2015.

Endemic Fauna Of Spain
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
