Tristramella Simonis
''Tristramella simonis'', the short jaw tristramella, is a vulnerable species of cichlid fish from the Jordan River system, including Lake Tiberias (Kinneret), in Israel and Syria, with introduced populations in the Nahr al-Kabir and Orontes basins in Syria. It prefers waters with little or no movement. Along with other tilapias, ''T. simonis'' is commonly caught as a food fish in parts of its range and it is commercially important in Lake Tiberias. Conservation status and taxonomy It is the only member of the genus ''Tristramella'' that remains extant, but it is vulnerable according to the IUCN. Primary threats are water extraction and climate change reducing the rain in its range. Other potential threats are uncontrolled fishing, and outbreaks of a viral disease that causes blindness in tilapia, including ''T. simonis''. The species survives in less than ten locations. The primary location is Lake Tiberias where it remained common, the population was not threatened and fishe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louis Charles Émile Lortet
Louis Charles Émile Lortet (22 August 1836 – 26 December 1909) was a French physician, botanist, zoologist and Egyptologist who was a native of Oullins. He earned his medical doctorate in 1861, and his degree in natural sciences in 1867. He served as premier doyen at the Faculty of Medicine of Lyon from 1877 until 1906. Also, from 1868 to 1909, he was director of the natural history museum in Lyon. Lortet is remembered for his scientific and zoological expeditions to the Middle East (Syria, Lebanon and Egypt). He performed studies of mummified animals from the New Kingdom of ancient Egypt, and in 1880 took part in an excavation of a Phoenician necropolis. Lortet was a member of numerous scientific societies, such as the ''Société de géographie de Lyon'', being a founding member in 1858. Species with the epithet of ''lorteti'' are named in his honor; an example being the pufferfish species ''Carinotetraodon lorteti''. Family His Grandmother Clémence Lortet (17 September ...

Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

Meristics
Meristics is an area of ichthyology and herpetology which relates to counting quantitative features of fish and reptiles, such as the number of fins or scales. A meristic (countable trait) can be used to describe a particular species of fish, or used to identify an unknown species. Meristic traits are often described in a shorthand notation called a ''meristic formula''. Meristic characters are the countable structures occurring in series (e.g. myomeres, vertebrae, fin rays) in fish. These characters are among the characters most commonly used for differentiation of species and populations. In the salmonids, scale counts have been most widely used for the differentiation of populations within species. In rainbow and steelhead trout the most notable differences among populations occur in counts of scales. Meristic characters are used in many other fields, such as in botany or in zoology. Meristic comparison is used in phenetic and cladistic analysis. Meristic analysis A meristic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olive (color)
Olive is a dark yellowish-green color, like that of unripe or green olives. As a color word in the English language, it appears in late Middle English. Shaded toward gray, it becomes olive drab. Variations Olivine Olivine is the typical color of the mineral olivine. The first recorded use of ''olivine'' as a color name in English was in 1912. Olive drab Olive drab is variously described as a "dull olive-green colour" (''Oxford English Dictionary'');''Oxford English Dictionary'', 5th Edition, 1982 "a shade of greenish-brown" (''Webster's New World Dictionary''); "a dark gray-green" (''MacMillan English dictionary''); "a grayish olive to dark olive brown or olive gray" (''American Heritage Dictionary''); or "A dull but fairly strong gray-green color" (''Collins English Dictionary''). It was widely used as a camouflage color for uniforms and equipment in the armed forces, particularly by the U.S. Army during the Second World War. The first recorded use of ''olive ...

Tristramella Sacra
''Tristramella sacra'', the long jaw tristramella, is a species of cichlid fish that was endemic to the Sea of Galilee in Israel. It has not been recorded since 1990, despite searches both of the lake and in local markets, and it is regarded as extinct by the IUCN. This species could reach a total length of up to . ''T. sacra''s spawning ground was the marshy northern margin of the lake. This dried out in 1991 and again in the mid-1990s, destroying this species' breeding habitat and therefore possibly causing its disappearance. Water levels in the Sea of Galilee may have been under stress since Israel's National Water Carrier was built in 1964, and this stress may have been increased since the Israel–Jordan peace treaty of 1994 committed Israel to supply 50 million cubic meters of water per year from the lake to Jordan.

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, 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 binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

Catalog Of Fishes
Catalog of Fishes is a comprehensive on-line database and reference work on the scientific names of fish species and genera. It is global in its scope and is hosted by the California Academy of Sciences. It has been compiled and is continuously updated by the curator emeritus of the CAS fish collection, William N. Eschmeyer. The taxonomy maintained by the Catalog of Fishes is considered authoritative and it is used as a baseline reference for instance by the broader global fish database FishBase, which involves cross-references to the Catalog's information for all accepted taxa. , the searchable catalogue contains entries for about 58,300 fish species names, about 33,400 of which are currently accepted (valid), and for some 10,600 genera (5,100 valid).

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...
