Ronald E
Ronald is a masculine given name derived from the Old Norse ''Rögnvaldr'', Hanks; Hardcastle; Hodges (2006) p. 234; Hanks; Hodges (2003) § Ronald. or possibly from Old English '' Regenweald''. In some cases ''Ronald'' is an Anglicised form of the Gaelic ''Raghnall'', a name likewise derived from ''Rögnvaldr''. The latter name is composed of the Old Norse elements ''regin'' ("advice", "decision") and ''valdr'' ("ruler"). ''Ronald'' was originally used in England and Scotland, where Scandinavian influences were once substantial, although now the name is common throughout the English-speaking world. A short form of ''Ronald'' is ''Ron''. Pet forms of ''Ronald'' include ''Roni'' and ''Ronnie''. ''Ronalda'' and ''Rhonda'' are feminine forms of ''Ronald''. '' Rhona'', a modern name apparently only dating back to the late nineteenth century, may have originated as a feminine form of ''Ronald''. Hanks; Hardcastle; Hodges (2006) pp. 230, 408; Hanks; Hodges (2003) § Rhona. The names ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphidromous
Fish migration is mass relocation by fish from one area or body of water to another. Many types of fish migrate on a regular basis, on time scales ranging from daily to annually or longer, and over distances ranging from a few metres to thousands of kilometres. Such migrations are usually done for better feeding or to reproduce, but in other cases the reasons are unclear. Fish migrations involve movements of schools of fish on a scale and duration larger than those arising during normal daily activities. Some particular types of migration are ''anadromous'', in which adult fish live in the sea and migrate into fresh water to spawn; and ''catadromous'', in which adult fish live in fresh water and migrate into salt water to spawn. Marine forage fish often make large migrations between their spawning, feeding and nursery grounds. Movements are associated with ocean currents and with the availability of food in different areas at different times of year. The migratory movements ma ...

Freshwater
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ 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, subterranean rivers and lakes. Fresh water is the 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 water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh wa ...

Goby
Goby is a common name for many species of small to medium sized ray-finned fish, normally with large heads and tapered bodies, which are found in marine, brackish and freshwater environments. Traditionally most of the species called gobies have been classified in the order Perciformes as the suborder Gobioidei but in the 5th Edition of ''Fishes of the World'' this suborder is elevated to an order Gobiiformes within the clade Percomorpha. Not all the species in the Gobiiformes are referred to as gobies and the "true gobies" are placed in the family Gobiidae, while other species referred to as gobies have been placed in the Oxudercidae. Goby is also used to describe some species which are not classified within the order Gobiiformes, such as the engineer goby or convict blenny ''Pholidichthys leucotaenia''. The word goby derives from the Latin ''gobius'' meaning "gudgeon", and some species of goby, especially the sleeper gobies in the family Eleotridae and some of the dartfishes are ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sri Lanka
Sri Lanka (, ; si, ශ්රී ලංකා, Śrī Laṅkā, translit-std=ISO (); ta, இலங்கை, Ilaṅkai, translit-std=ISO ()), formerly known as Ceylon and officially the Democratic Socialist Republic of Sri Lanka, is an island country in South Asia. It lies in the Indian Ocean, southwest of the Bay of Bengal, and southeast of the Arabian Sea; it is separated from the Indian subcontinent by the Gulf of Mannar and the Palk Strait. Sri Lanka shares a maritime border with India and Maldives. Sri Jayawardenepura Kotte is its legislative capital, and Colombo is its largest city and financial centre. Sri Lanka has a population of around 22 million (2020) and is a multinational state, home to diverse cultures, languages, and ethnicities. The Sinhalese are the majority of the nation's population. The Tamils, who are a large minority group, have also played an influential role in the island's history. Other long established groups include the Moors, the Burghers ...

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries 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 hypural plate. Simply put, this measurement excludes the length of the 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 bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes. Total length meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cedric Martenstyn
Cedric () is a masculine given name invented by Walter Scott in the 1819 novel ''Ivanhoe''.Sir Walter Scott, Graham Tulloch (ed.), ''Ivanhoe'', vol. 8 of The Edinburgh Edition of the Waverley Novels, Edinburgh University Press, 1998, , "explanatory notes", p. 511. The invented name is based on '' Cerdic'', the name of a 6th-century Anglo-Saxon king (itself from Brittonic '' Coroticus''). The name was not popularly used until the children's book '' Little Lord Fauntleroy'' by Frances Hodgson Burnett was published in 1885 to 1886, the protagonist of which is called Cedric Errol. The book was highly successful, causing a fashion trend in children's formal dress in America and popularized the given name. People named Cedric born in the years following the novel's publication include British naval officer Cedric Holland (1889–1950), American war pilot Cedric Fauntleroy (1891–1973), Irish art director Austin Cedric Gibbons (1893–1960) and British actor Cedric Hardwicke ...

Liberation Tigers Of Tamil Eelam
The Liberation Tigers of Tamil Eelam (LTTE; ta, தமிழீழ விடுதலைப் புலிகள், translit=Tamiḻīḻa viṭutalaip pulikaḷ, si, දෙමළ ඊළාම් විමුක්ති කොටි, translit=Damiḷa īḷām vimukthi koṭi; also known as the Tamil Tigers) was a Tamil militant organization that was based in northeastern Sri Lanka. The LTTE fought to create an independent Tamil state called Tamil Eelam in the north-east of the island, due to the continuous discrimination and violent persecution against Sri Lankan Tamils by the Sinhalese dominated Sri Lankan Government.T. Sabaratnam, Pirapaharan, Volume 1, Introduction (2003)T. Sabaratnam, Pirapaharan, Volume 1, Chapter 1: Why didn't he hit back?

Stiphodon
''Stiphodon'' is a genus of freshwater gobies. They inhabit swift, clear streams close to the sea and are found in large parts of Asia and Oceania. Many of the 36 currently recognized species have extremely restricted distributions on single islands or even single streams. These are small gobies with bodies squarish in cross section. A female of Stiphodon multisquamus with a standard length of 60.4 mm is the largest ''Stiphodon'' individual on record. Species There are currently 36 recognized species in this genus: * '' Stiphodon alcedo'' Maeda, Mukai & Tachihara, 2012 * '' Stiphodon allen'' R. E. Watson, 1996 (Allen's stiphodon) * '' Stiphodon annieae'' Keith & Hadiaty, 2015 Keith, P. & Hadiaty, R.K. (2015): ''Stiphodon annieae'', a new species of freshwater goby from Indonesia (Gobiidae).

Freshwater Fish Of Sri Lanka
Sri Lanka is a tropical island situated close to the southern tip of India. It is situated in the middle of Indian Ocean. Because of being an island, Sri Lanka has many endemic freshwater fauna, including fish, crabs, molluscs, and other aquatic insects. Species List Class: Actinopterygii Freshwater fish are physiologically differ from marine and brackish water forms. The low salinity and high osmotic pressure makes them so different. Few fish can be found in all three ecological systems. There are 95 species of freshwater fish occur in the country, where 53 of those are endemic. 41% of all known species of fish of Sri Lanka are found in freshwater. There are about 70% of endemism of those fish. Most of them are listed into IUCN categories. Four ''Devario'' species were described in 2017 by Batuwita et al. However, the taxonomy and descriptions were cited as problematic by fellow local ichthyologists. Note: introduced species are not included in the list. Go to '' List of intro ...

Taxa Named By Ronald E
In biology, a taxon (back-formation from ''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 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 system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
