Pliomeridius is an extinct genus of trilobite in the family Pliomeridae. [1] [2]
A genus is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. 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.
A pine is any conifer in the genus Pinus of the family Pinaceae. Pinus is the sole genus in the subfamily Pinoideae. The Plant List compiled by the Royal Botanic Gardens, Kew and Missouri Botanical Garden accepts 126 species names of pines as current, together with 35 unresolved species and many more synonyms. Pine may also refer to the lumber derived from pine trees; pine is one of the more extensively used types of wood used as lumber.
Chaetognatha is a phylum of predatory marine worms that are a major component of plankton worldwide. Commonly known as arrow worms, about 20% of the known Chaetognatha species are benthic, and can attach to algae and rocks. They are found in all marine waters, from surface tropical waters and shallow tide pools to the deep sea and polar regions. Most chaetognaths are transparent and are torpedo shaped, but some deep-sea species are orange. They range in size from 2 to 120 millimetres.
Pangolins, sometimes known as scaly anteaters, are mammals of the order Pholidota. The one extant family, Manidae, has three genera: Manis, Phataginus and Smutsia. Manis comprises the four species found in Asia, while Phataginus and Smutsia each include two species living in Sub-Saharan Africa. These species range in size from 30 to 100 cm. A number of extinct pangolin species are also known.
Coronaviruses are a group of related RNA viruses that cause diseases in mammals and birds. In humans and birds, they cause respiratory tract infections that can range from mild to lethal. Mild illnesses in humans include some cases of the common cold, while more lethal varieties can cause SARS, MERS, and COVID-19. In cows and pigs they cause diarrhea, while in mice they cause hepatitis and encephalomyelitis. There are as yet no vaccines or antiviral drugs to prevent or treat human coronavirus infections.
The rails, or Rallidae, are a large cosmopolitan family of small- to medium-sized, ground-living birds. The family exhibits considerable diversity and includes the crakes, coots, and gallinules. Many species are associated with wetlands, although the family is found in every terrestrial habitat except dry deserts, polar regions, and alpine areas above the snow line. Members of the Rallidae occur on every continent except Antarctica. Numerous island species are known. The most common rail habitats are marshland and dense forest. They are especially fond of dense vegetation.
The Vombatiformes are one of the three suborders of the large marsupial order Diprotodontia. Five of the seven known families within this suborder are extinct; only the families Phascolarctidae, with the koala, and Vombatidae, with three extant species of wombat, survive.
Apocynaceae is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison. Members of the family are native to the European, Asian, African, Australian, and American tropics or subtropics, with some temperate members. The former family Asclepiadaceae is considered a subfamily of Apocynaceae and contains 348 genera. A list of Apocynaceae genera may be found here.
Delphinium is a genus of about 300 species of perennial flowering plants in the family Ranunculaceae, native throughout the Northern Hemisphere and also on the high mountains of tropical Africa. The genus was erected by Carl Linnaeus.
Daphne is a genus of between 70 and 95 species of deciduous and evergreen shrubs in the family Thymelaeaceae, native to Asia, Europe and north Africa. They are noted for their scented flowers and often brightly coloured berries. Two species are used to make paper. Many species are grown in gardens as ornamental plants; the smaller species are often used in rock gardens. All parts of daphnes are poisonous, especially the berries.
Trimerus is an extinct genus of trilobite in the family Homalonotidae. There is one described species in Trimerus, T. dekayi.
Kinosternoidea is a superfamily of aquatic turtles, which includes two families: Dermatemydidae, and Kinosternidae.
Genus plc is a British-based business selling products manufactured using biotechnology to cattle and pig farmers. It is headquartered in Basingstoke and is a constituent of the FTSE 250 Index.
Iguana is a genus of herbivorous lizards that are native to tropical areas of Mexico, Central America, South America, and the Caribbean. The genus was first described in 1768 by Austrian naturalist Josephus Nicolaus Laurenti in his book Specimen Medicum, Exhibens Synopsin Reptilium Emendatam cum Experimentis circa Venena. There were formerly considered to be only two species in the genus; the green iguana, which is widespread throughout its range and a popular pet, and the Lesser Antillean iguana, which is native to the Lesser Antilles; however, genetic analysis indicates that the green iguana may comprise a species complex of multiple species, some of which have been recently described.
Cryphops is an extinct genus of trilobite in the family Phacopidae. There are at least three described species in Cryphops.
Macrocheles is a genus of mites in the family Macrochelidae. There are more than 100 described species in Macrocheles.
The Interim Register of Marine and Nonmarine Genera (IRMNG) is a taxonomic database which attempts to cover published genus names for all domains of life from 1753 in zoology up to approximately 2014, arranged in a single, internally consistent taxonomic hierarchy, for the benefit of Biodiversity Informatics initiatives plus general users of biodiversity (taxonomic) information. In addition to containing over 490,000 published genus name instances as at March 2020, the database holds over 1.7 million species names, although this component of the data is not maintained in as current or complete state as the genus-level holdings. IRMNG can be queried online for access to the latest version of the dataset and is also made available as periodic snapshots or data dumps for import/upload into other systems as desired.
Peramus is the only confirmed genus in the family Peramuridae, and a possible ancestor of early therians. It lived in the Late Jurassic and Early Cretaceous period.
Botourmiaviridae is a family of viruses.
