Rovella
''Sarmarutilus'' is a monospecific genus of freshwater ray-finned fish belonging to the family Leuciscidae, which includes the daces, Eurasian minnows and related fishes. The only species in this genus is ''Sarmarutilus rubilio'', known as the rovella, South European roach or the Apennine roach, a species endmeic to the Italian peninsula. Taxonomy ''Sarmarutilus'' was first proposed as a genus in 2014 by Pier Giorgio Bianco and Valerio Ketmaier with '' Leuciscus rubilio'' being its type species by monotypy. ''L. rubilio'' was first formally described in 1837 by the French art collector and biologist Charles Lucien Bonaparte with its type locality given as Lake Nemi. ''L. rubilio'' was subsequently classified in the genus ''Rutilus'' but was which was reclassified in 2014 into the new monotypic ''Sarmarutilus''. This lineage is thought to have originated in the Sarmatic Sea in the Middle Miocene and reached the Mediterranean area during the Lago Mare phase, and then survive ...

Type Locality (biology)
In biology, a type is a particular wikt:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the ...

Sele (river)
The Sele is a river in southwestern Italy. Originating from the Monti Picentini in Caposele,Meaning "top of the Sele" it flows through the region of Campania, in the provinces of Salerno and Avellino. Its mouth is in the Gulf of Salerno, on the Tyrrhenian Sea, at the borders between the municipalities of Eboli and Capaccio (not too far from Paestum), in the beginning point of Cilentan Coast. History The important Greek site of Foce del Sele, a sanctuary complex dedicated to the goddess Hera, is at the ancient mouth of the river, though little remains on the site; the relief friezes and other finds are now in the museum at Paestum. At this period the Sele represented the border of the Greek and Etruscan zones of influence along the coast. Hydrography In terms of average water discharge of southern Italian rivers, it is second only to the Volturno. Its main tributaries are the Tanagro, the Calore Lucano and the Tenza. In ancient times it was known as Silarus. This river is th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magra
__NOTOC__ The Magra is a long river of Northern Italy, which runs through Pontremoli, Filattiera, Villafranca in Lunigiana and Aulla in the province of Massa-Carrara (Tuscany); Santo Stefano di Magra, Vezzano Ligure, Arcola, Sarzana and Ameglia in the province of La Spezia (Liguria). In Roman times, it was known as the Macra and marked the eastern boundary of the territory of Liguria. The river's drainage basin occupies around . Its most important tributary is the Vara which joins the Magra from the right within the commune of Santo Stefano di Magra. Caprigliola bridge collapse In April 2020 a 260 metre long road bridge across the Magra at Albiano Magra near Aulla collapsed. Very few vehicles were using the bridge at the time due to the coronavirus lockdown then in force, and only two people were injured. Regional Natural Park of Montemarcello-Magra-Vara Since 1995 an area of surrounding the Magra and Vara rivers is protected by a natural park of the '' r ...

Standard Length
Fish measurement is the measuring of individual fish and various parts of fish anatomy, their anatomies, for data used in many areas of ichthyology, including Taxonomy (biology), taxonomy and fishery biology. Overall length Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the Glossary of ichthyology#H, hypural plate. This measurement excludes the length of the caudal fin, caudal (tail) fin. Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most Actinopterygii, bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys) and usually Elasmobranchii (shark ...

Nuptial Tubercles
Nuptial tubercles or breeding tubercles (also called pearl organs or nuptial efflorescence) are noticeable skin roughness or horny nodules that form on male fish during breeding. They are made of keratin, the same material as hair, hooves, and fingernails. Use and description These tubercles are dermal structures present in 15 families of fish belonging to 4 orders of Actinopterygii – Salmoniformes, Gonorhynchiformes, Cypriniformes and Perciformes are used in the courtship and reproduction process. They consist of partially or fully keratinised cells that form in certain regions, used to stimulate females during courtship. Their development is stimulated by hormones secreted by the pituitary and adrenal glands, and is induced shortly before the breeding season and discarded after. In some species, at least, there is a correlation between the level of androgens present in the endocrine system and the volume and complexity of tubercle growth. They normally form on the he ...

Synonym (taxonomy)
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The Botanical nomenclature, botanical and Zoological nomenclature, zoological codes of nomenclature treat the concept of synonymy differently. * In nomenclature, botanical nomenclature, a synonym is a Binomial nomenclature, scientific name that applies to a taxon that now goes by a different scientific name. For example, Carl Linnaeus, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different Binomial nomenclature, binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet, species epithet, or epitheton) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Etymology Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the ...

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] |
