Xenopoecilus Sarasinorum
''Oryzias sarasinorum'', the Sarasins minnow or Sarasins buntingi, is a species of ricefish in the Adrianichthyidae. It is endemic to Lake Lindu in Lore Lindu National Park, Sulawesi, Indonesia. This species was described as ''Haplochilus sarasinorum'' by C.M.L. Popta in 1905 and she named it in honour of the Swiss naturalists and second cousins Paul Sarasin (1856-1929) and Fritz Sarasin (1859-1942), the latter being the collector of the type. Although the IUCN state that the population of this fish is stabled it is threatened by introduced non native fish, common carp, Mozambique tilapia and walking catfish The walking catfish (''Clarias batrachus'') is a species of freshwater airbreathing catfish native to Southeast Asia. It is named for its ability to "walk" and wiggle across dry land, to find food or suitable environments.

Canna Maria Louise Popta
Canna Maria Louise Popta (31 May 1860 – 13 June 1929)L.B. Holthuis, Biography i1820-1958, Rijksmuseum van Natuurlijke Historie page 82 (in Dutch). was a Dutch biologist. Born in Breda, Popta was one of the first women to enrol as a student at Leiden University where she studied for a degree in geology, zoology and botany, allowing her to teach in high schools. She studied for her doctorate at the University of Berne under the supervision of Eduard Fischer, her thesis was on the Hemiasci, a fungal group which was then thought to be the link between the Phycomycetes and Ascomycota. After completing her doctorate she obtained a position at the Rijksmuseum van Natuurlijke Historie in Leiden as a Lab Assistant to the curator of reptiles, amphibians and fishes. During her career at the museum she concentrated mainly on ichthyology, eventually retiring in 1928, and dying the following year in Leiden. She wrote over 40 scientific papers and a number of articles for encyclopedias. For e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. 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 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 scientific name of every taxon is almost al ...

Taxonomy Articles Created By Polbot
Taxonomy is the practice and science of categorization or classification (general theory), classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a Taxonomy for search engines, search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchy, hierarchies (and thus, have an intrinsic tree structure), but not all are. Originally, taxonomy referred only to the categorisation of organisms or a particular categorisation of organisms. In a wider, more general sense, it may refer to a categorisation of things or concepts, as well as to the principles underlying such a categorisation. Taxonomy organizes taxonomic uni ...

Taxa Named By Canna Maria Louise Popta
In biology, a taxon (back-formation from ''Taxonomy (biology), taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular Taxonomic rank, ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of bio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Fish Of Indonesia
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salt (chemistry), salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non-saltiness, salty mineral water, mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen water, frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ice pellets, sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranea (geography), subterranean subterranean river, rivers and underground lake, lakes. Fresh water is the Water resources, water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt wa ...

Oryzias
''Oryzias'' is a genus of ricefishes native to fresh and brackish water in east and south Asia. Some species are widespread and the Japanese rice fish (''O. latipes'') is commonly used in science as a model organism, while others have very small ranges and are threatened. They are small, up to long, and most are relatively plain in colour. The genus name ''Oryzias'' is a reference to the scientific name for rice, '' Oryza''. They have an unusual reproductive behavior where the female facultatively carries the eggs in a cluster at the pelvic or anal fins for a period after they have been fertilized. Species There are currently 33 recognized species in this genus: * '' Oryzias asinua'' Parenti, Hadiaty, Lumbantobing & Herder, 2013 * '' Oryzias bonneorum'' Parenti, 2008 * '' Oryzias carnaticus'' Jerdon, 1849 * '' Oryzias celebensis'' M.

Walking Catfish
The walking catfish (''Clarias batrachus'') is a species of freshwater airbreathing catfish native to Southeast Asia. It is named for its ability to "walk" and wiggle across dry land, to find food or suitable environments. While it does not truly walk as most bipeds or quadrupeds do, it has the ability to use its pectoral fins to keep it upright as it makes a wiggling motion with snakelike movements to traverse land. This fish normally lives in slow-moving and often stagnant waters in ponds, swamps, streams, and rivers, as well as in flooded rice paddies, or temporary pools that may dry up. When this happens, its "walking" skill allows the fish to move to other aquatic environments. Considerable taxonomic confusion surrounds this species and it has frequently been confused with other close relatives.Ng, Heok Hee, and Kottelat, Maurice (2008). ''The identity of Clarias batrachus (Linnaeus, 1758), with the designation of a neotype (Teleostei: Clariidae).'' Zoological Journal of th ...

Mozambique Tilapia
The Mozambique tilapia (''Oreochromis mossambicus'') is an oreochromine cichlid fish native to southeastern Africa. Dull colored, the Mozambique tilapia often lives up to a decade in its native habitats. It is a popular fish for aquaculture. Due to human introductions, it is now found in many tropical and subtropical habitats around the globe, where it can become an invasive species because of its robust nature. These same features make it a good species for aquaculture because it readily adapts to new situations. It is known as black tilapia in Colombia and as blue kurper in South Africa. Description The native Mozambique tilapia is laterally compressed, and has a deep body with long dorsal fins, the front part of which have spines. Native coloration is a dull greenish or yellowish, and weak banding may be seen. Adults reach up to in standard length and up to . Size and coloration may vary in captive and naturalized populations due to environmental and breeding pressures. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Carp
The Eurasian carp or European carp (''Cyprinus carpio''), widely known as the common carp, is a widespread freshwater fish of eutrophic waters in lakes and large rivers in Europe and Asia.Fishbase''Cyprinus carpio'' Linnaeus, 1758/ref>Arkive The native wild populations are considered vulnerable to extinction by the International Union for Conservation of Nature (IUCN), but the species has also been domesticated and introduced (see aquaculture) into environments worldwide, and is often considered a destructive invasive species, being included in the list of the world's 100 worst invasive species. It gives its name to the carp family, Cyprinidae. Taxonomy The two subspecies are: * ''Cyprinus carpio carpio'', native to much of Europe (notably the Danube and Volga rivers)Jian Feng Zhou, Qing Jiang Wu, Yu Zhen Ye & Jin Gou Tong (2003).

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
