Brian R
Brian (sometimes spelled Bryan in English) is a male given name of Irish and Breton origin, as well as a surname of Occitan origin. It is common in the English-speaking world. It is possible that the name is derived from an Old Celtic word meaning "high" or "noble". For example, the element ''bre'' means "hill"; which could be transferred to mean "eminence" or "exalted one". The name is quite popular in Ireland, on account of Brian Boru, a 10th-century High King of Ireland. The name was also quite popular in East Anglia during the Middle Ages. This is because the name was introduced to England by Bretons following the Norman Conquest. Bretons also settled in Ireland along with the Normans in the 12th century, and 'their' name was mingled with the 'Irish' version. Also, in the north-west of England, the 'Irish' name was introduced by Scandinavian settlers from Ireland. Within the Gaelic-speaking areas of Scotland, the name was at first only used by professional families of Iris ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dirk U
A dirk is a long-bladed thrusting dagger.Chisholm, Hugh (ed.); "Dagger", ''Encyclopædia Britannica'', 11th ed., Vol. VII, New York, NY: Cambridge University Press (1910), p. 729. Historically, it gained its name from the Highland dirk (Scottish Gaelic ) where it was a personal weapon of officers engaged in naval hand-to-hand combat during the Age of SailO'Brian, Patrick; ''Men-of-War: Life in Nelson's Navy'', New York: W. W. Norton & Co., (1974), p. 35. as well as the personal sidearm of Highlanders. It was also the traditional sidearm of the Highland Clansman and later used by the officers, pipers, and drummers of Scottish Highland regiments around 1725 to 1800 and by Japanese naval officers. Etymology The term is associated with Scotland in the Early Modern Era, being attested from about 1600. The term was spelled ''dork'' or ''dirk'' during the 17th century,Head, T.

Killifish
A killifish is any of various oviparous (egg-laying) cyprinodontiform fish, including families Aplocheilidae, Pantanodontidae, Cyprinodontidae, Fundulidae, Nothobranchiidae, Profundulidae, Aphaniidae and Valenciidae. All together, there are 1,270 species of killifish, the biggest family being Rivulidae, containing more than 320 species. As an adaptation to living in ephemeral waters, the eggs of most killifish can survive periods of partial dehydration. Many of the species rely on such a diapause, since the eggs would not survive more than a few weeks if entirely submerged in water. The adults of some species, such as ''Kryptolebias marmoratus'', can additionally survive out of the water for several weeks. Most killifish are small, measuring from , with the largest species growing to just under . The word ''killifish'' is of uncertain origin, but is likely to have come from the Dutch ''kil'' for a kill (small stream). Although killifish is sometimes used as an English eq ...

Nothobranchiidae
Nothobranchiidae are a Family (biology), family of Osteichthyes, bony fishes containing roughly 300 species, also known as African rivulines. They are small killifish, usually measuring about . They are limited to Africa, living in fresh water but being also somewhat salt-tolerant. They are also found in muddy or brackish water. Some species are kept as aquarium pets. They have frilly fins and many are brightly colored. They were formerly included in the family Aplocheilidae (which was later limited to Madagascar, Malagasy, Seychelles, Seychellean and Asian species); a return to that broader family has recently been suggested. Members of genus ''Nothobranchius'' are found in mud pools on the plains of Africa, a habitat shared by no other fish except the lungfishes. Their life cycle is only a year long, and they die when the pools dry up, however the species survives because their eggs remain inactive (in diapause) in the dry bottom Substrate (biology), substrate throughout the dr ...

Endemism
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Tanzania
Tanzania, officially the United Republic of Tanzania, is a country in East Africa within the African Great Lakes region. It is bordered by Uganda to the northwest; Kenya to the northeast; the Indian Ocean to the east; Mozambique and Malawi to the south; Zambia to the southwest; and Rwanda, Burundi, and the Democratic Republic of the Congo to the west. According to a 2024 estimate, Tanzania has a population of around 67.5 million, making it the most populous country located entirely south of the equator. Many important hominid fossils have been found in Tanzania. In the Stone and Bronze Age, prehistoric migrations into Tanzania included South Cushitic languages, Southern Cushitic speakers similar to modern day Iraqw people who moved south from present-day Ethiopia; Eastern Cushitic people who moved into Tanzania from north of Lake Turkana about 2,000 and 4,000 years ago; and the Southern Nilotic languages, Southern Nilotes, including the Datooga people, Datoog, who originated fro ...

Wembere
The Wembere River is a river located in north western Singida Region, Tanzania. The river is part of the water basin of Lake Eyasi. The Wembere River originates in hilly country in central Tanzania at 6.0º south, and flows northwards through a branch of the Eastern Rift Valley. Its tributary the Nyahua River forms a seasonal floodplain 60 miles long and 1-5 km wide, covering 11,000 ha. After the Nyahua joins the Wembere from the northwest, the Wembere widens into a larger floodplain 105 km long and up to 20 km wide, and covering 140,000 ha. (4º12'-5º01' S/33º47'-34º11' E). Other tributaries are the Wamba, which joins from the northeast, the Mwaru, which joins from the east, and the Mapiringa, which joins from the west. The floodplain consists of flooded grasslands, inundated during the wet season and laced with drainage channels. Stands of the trees ''Vachellia seyal'' and ''Vachellia drepanolobium'' edge the seasonally-flooded portion of the plain. Above the floodplain, t ...

Nothobranchius
''Nothobranchius'' is a genus of small, freshwater killifish, classified in the family Nothobranchiidaevan der Laan, R., Eschmeyer, W.N. & Fricke, R. (2014)Family-group names of Recent fishes.''Zootaxa, 3882 (2): 1–230.'' in the order Cyprinodontiformes. There are about a hundred species in the genus, many with very small distributions. They are primarily native to East Africa from Sudan to northern South Africa, whereas a dozen species are found in the upper Congo River Basin; the greatest species richness is in Tanzania. ''Nothobranchius'' typically inhabit ephemeral pools that are filled only during the monsoon season, and show extreme life-history adaptations to survive the dry season. When their habitats dry up, the adult fish die and the eggs survive encased in the clay during the dry season. The embryos survive the dry season by entering diapause, facilitated by their specialized eggs that have a very hard chorion and are resistant to desiccation and hypoxia.Alexander Do ...

Fish Described In 2020
A fish (: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communicate acoustically with each other, such as during courtship displays. The study of fish is known as ichthyology. The earliest fish appeared during the Cambrian as small filter feeders; they continued to evolve through the Paleozoic, diversifying into many forms. The earliest fish wi ...
