Luciopercinae
The Luciopercinae is a subfamily of ray-finned fish, classified within the Family (biology), family Percidae, the subfamily includes the pike-perches and zingels. The pike-perches of the genus ''Zander, Sander'' have an Holarctic distribution while the zingels of the Tribe (biology), tribe Romanichthyini are found in Europe. They are largely freshwater species but some can be found in brackish water. Characteristics The species within the Luciopercinae have a number of morphological characteristics in common. These are the possession of weak spines in the anal fin, the lateral line extending as far as the margin of the caudal fin and additional lines over and under the main lateral line, having a cleithrum which does not have serrations on the pectoral girdle, and having a vertebra count of 41–50. Distribution The Luciopercinae has a Holarctic distribution, the pike-perches of the genus ''Sander'' are found in Eurasia and North America and includes such commercially important s ...

Romanichthyini
Romanichthyini is a tribe (taxonomy), tribe of freshwater ray-finned fish which is one of two tribes in the subfamily Luciopercinae, which in turn is classified under the Family (biology), family Percidae, the family also includes the perches, Sander (fish), pikeperches, Gymnocephalus, ruffes and Darter (fish), darters. Taxonomy The Romanichthyini is the sister taxon to the tribe Luciopercini and together they form the subfamily Luciopercinae. There are two genera classified within the tribe, although there is evidence to suggest that it may be a single genus and that the asprete should be classified within ''Zingel''. Apart from one species which is found in the Rhone the species in the tribe are endemism, endemic to the Danube basin. The two genera are: * ''Romanichthys'' Dumitrescu, Bănărescu & Stoica 1957 * ''Zingel'' Hippolyte Cloquet, Cloquet, 1817 References {{Taxonbar, From=Q97495923 Luciopercinae Fish tribes ...

Luciopercini
''Sander'' (formerly known as ''Stizostedion'') is a genus of predatory ray-finned fish in the family Percidae, which also includes the perches, ruffes, and darters. They are also known as "pike-perch" because of their resemblance to fish in the unrelated Esocidae (pike) family. They are the only genus in the monotypic tribe Luciopercini, which is one of two tribes in the subfamily Luciopercinae. The earliest known fossils of this genus are partial jaw and vertebrae elements from the middle Miocene (Barstovian)-aged Wood Mountain Formation of Saskatchewan, Canada. Characteristics ''Sander'' species have elongated and laterally compressed bodies and they range in total length from in the Volga pikeperch (''S. volgensis'') to in the zander (''S. lucioperca''). The species within the genus share canine-like teeth that are at their largest in the zander, and although they are not present in adult Volga pikeperches, they do possess them as juveniles. in addition, they have thin ro ...

Zingel
''Zingel'' is a genus of fish in the family Percidae. They are long and slender, reaching in length. They are found in rivers and streams in Europe. They feed mainly on aquatic invertebrates such as crustaceans and insect larvae, and also eat small fish. While they were all classed as endangered or vulnerable in the past, environmental improvements have allowed some to be reclassified to least concern. Species The genus contains these species: *'' Zingel asper'' (Linnaeus, 1758) (Rhone streber) *'' Zingel balcanicus'' ( S. L. Karaman, 1937) (Vardar streber) *'' Zingel streber'' (Siebold, 1863) (Danube streber) *'' Zingel zingel'' (Linnaeus Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming o ..., 1766) (Zingel) References Luciopercinae Taxa named by Hippolyte Cloquet Taxo ...

Romanichthys
''Romanichthys'' is a genus of ray-finned fish. It is one of two genera in the tribe Romanichthyini which, along with the tribe Luciopercini, forms the subfamily Luciopercinae of the family Percidae. This happens alongside the perches, ruffes, and darters. The genus contains the single species ''Romanichthys valsanicola'', known as the sculpin-perch, asprete, or Romanian darter. This fish was described in 1957 by Romanian student scientists M. Dumitrescu, P. Bănărescu, and N. Stoica. Local names include ''asprete'', ''poprete'', and ''sforete''. Endemic to a very restricted area in southern Romania, it was found in the upper reach of the Argeş River and in two of its tributaries: Râul Doamnei and Vâlsan. Due to hydrotechnical constructions and deterioration of its habitat, it survived only in the tributary Vâlsan. Description ''R. valsanicola'' is a small, greyish-brown fish growing to about long, covered with small, rough scales. It can be distinguished from oth ...

Percidae
The Percidae are a family of ray-finned fish, part of the order Perciformes, which are found in fresh and brackish waters of the Northern Hemisphere. The majority are Nearctic, but there are also Palearctic species. The family contains nearly 250 species in 12 genera. The perches and their relatives are in this family; well-known species include the walleye, sauger, ruffe, and three species of perch. However, small fish known as darters are also a part of this family. Despite the widespread and speciose nature of this family, the vast majority of its species diversity is within the darters, which are restricted to eastern North America, and the majority of which have small ranges. Excluding the darters, this family contains only 20 species. In Europe, percids were likely a more ecologically dominant group in the past than now, with the immigration of cyprinids to Europe during the Miocene causing a decline in their importance. Characteristics The family is characterised by ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene
The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene followed the Oligocene and preceded the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertebra
Each vertebra (: vertebrae) is an irregular bone with a complex structure composed of bone and some hyaline cartilage, that make up the vertebral column or spine, of vertebrates. The proportions of the vertebrae differ according to their spinal segment and the particular species. The basic configuration of a vertebra varies; the vertebral body (also ''centrum'') is of bone and bears the load of the vertebral column. The upper and lower surfaces of the vertebra body give attachment to the intervertebral discs. The posterior part of a vertebra forms a vertebral arch, in eleven parts, consisting of two pedicles (pedicle of vertebral arch), two laminae, and seven processes. The laminae give attachment to the ligamenta flava (ligaments of the spine). There are vertebral notches formed from the shape of the pedicles, which form the intervertebral foramina when the vertebrae articulate. These foramina are the entry and exit conduits for the spinal nerves. The body of the vertebr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barstovian
The Barstovian North American Stage on the geologic timescale is the North American faunal stage according to the North American Land Mammal Ages chronology (NALMA), typically set from 16,300,000 to 13,600,000 years BP, a period of . It is usually considered to overlap the Langhian and Serravallian stages of the Middle Miocene. The Barstovian is preceded by the Hemingfordian and followed by the Clarendonian NALMA stages. The Barstovian can be further divided into the substages of: * late Late Barstovian: Lower boundary source of the base of the Langhian (approximate) * early Late Barstovian: Base of the Langhian (approximate) * early/lower Barstovian: Upper boundary source: base of Clarendonian (approximate) Correlations The Barstovian (15.97 to 13.6 Ma) correlates with: * SALMA ** Colloncuran (15.5-13.8 Ma) [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hippolyte Cloquet
Hippolyte Cloquet (10 March 1787 – 3 March 1840) was a French physician and anatomist who was a native of Paris. He was the brother of surgeon Jules Germain Cloquet (1790–1883), and father to Ernest Cloquet (1818–1855), who was a personal physician to Mohammad Shah Qajar of Persia. He studied medicine in Paris, where he earned his doctorate in 1815. In 1823 he became a member of the '' Académie de Médecine''. Cloquet was a pioneer in the field of rhinology, and in 1821 published '' Osphrésiologie, ou traité des odeurs'', which was a comprehensive treatise that discussed olfaction, diseases of the nose, deviations of the septum, rhinoplasty, et al. He was also author of ''Traité d'anatomie descriptive'', an influential French text of anatomy that ran through six editions. The fourth edition of this work was translated into English by anatomist Robert Knox (1791–1862). Cloquet also made contributions in the field of zoology, his treatise ''Poissons et Reptiles'' w ...

Lorenz Oken
Lorenz Oken (1 August 1779 – 11 August 1851) was a Germans, German natural history, naturalist, botany, botanist, biologist, and ornithology, ornithologist. Biography Oken was born Lorenz Okenfuss () in Bohlsbach (now part of Offenburg), Ortenau, Baden, and studied natural history and medicine at the universities of University of Freiburg, Freiburg and University of Würzburg, Würzburg. He went on to the University of Göttingen, where he became a ''Privatdozent'' (unsalaried lecturer), and shortened his name to Oken. As Lorenz Oken, he published a small work entitled ''Grundriss der Naturphilosophie, der Theorie der Sinne, mit der darauf gegründeten Classification der Thiere'' (1802). This was the first of a series of works which established him as a leader of the movement of "Naturphilosophie" in Germany. In it he extended to physical science the philosophical principles which Immanuel Kant (1724–1804) had applied to epistemology and morality. Oken had been preceded in t ...
