Robert M
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It can be use ...

Galaxiid
The Galaxiidae are a family of mostly small freshwater fish in the Southern Hemisphere. The majority live in Southern Australia or New Zealand, but some are found in South Africa, southern South America, Lord Howe Island, New Caledonia, and the Falkland Islands. One galaxiid species, the common galaxias (''Galaxias maculatus''), is probably the most widely naturally distributed freshwater fish in the Southern Hemisphere. They are coolwater species, found in temperate latitudes, with only one species known from subtropical habitats. Many specialise in living in cold, high-altitude upland and lowland (freshwater ecology), upland rivers, streams, and lakes. Some galaxiids live in fresh water all their lives, but many have a partially marine lifecycle. In these cases, larvae are hatched in a river, but are washed downstream to the ocean, later returning to rivers as juveniles to complete their development to full adulthood. This pattern differs from that of salmon, which only return ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Galaxias
''Galaxias'' is a genus of small freshwater fish in the family (biology), family Galaxiidae, and are frequently referred to as the galaxiids. These highly adaptable fish are typically found at temperate latitudes across the Southern Hemisphere. Galaxiids are fish scale, scaleless and somewhat tubular in body form, ranging from very slender to quite bulky. They are somewhat torpedo-shaped, with the dorsal fin, dorsal and anal fins positioned close to the tail. They are generally small, with typical adults ranging between in total length, with some stocky species attaining around . The largest, ''Galaxias argenteus'', has been recorded at , although is a more typical adult length. Species The 46 recognized species in this genus are: * ''Galaxias aequipinnis'' Tarmo Ain Raadik, Raadik, 2014 (East Gippsland Galaxias) * ''Galaxias anomalus'' Gerald Stokell, Stokell, 1959 (Roundhead Galaxias) * ''Galaxias arcanus'' Raadik, 2014 (Riffle Galaxias) * ''Galaxias argenteus'' Johann Fri ...

North Island
The North Island, also officially named Te Ika-a-Māui, is one of the two main islands of New Zealand, separated from the larger but much less populous South Island by the Cook Strait. The island's area is , making it the world's 14th-largest island. The world's 28th-most-populous island, Te Ika-a-Māui has a population of accounting for approximately % of the total residents of New Zealand. Twelve main urban areas (half of them officially cities) are in the North Island. From north to south, they are Whangārei, Auckland, Hamilton, Tauranga, Rotorua, Gisborne, New Plymouth, Napier, Hastings, Whanganui, Palmerston North, and New Zealand's capital city Wellington, which is located at the south-west tip of the island. Naming and usage Although the island has been known as the North Island for many years, in 2009 the New Zealand Geographic Board found that, along with the South Island, the North Island had no official name. After a public consultation, the board officially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Dargaville
Dargaville ( mi, Takiwira) is a town located in the North Island of New Zealand. It is situated on the bank of the Northern Wairoa River in the Kaipara District of the Northland region. The town is located 55 kilometres southwest of Whangārei. Dargaville is 174 kilometres north of Auckland. It is noted for the high proportion of residents of Croatian descent. The area around it is one of the chief regions in the country for cultivating kumara (sweet potato) and so Dargaville is known by many locals as the Kumara Capital of New Zealand. History and culture The town was named after timber merchant and politician Joseph Dargaville (1837–1896). Dargaville was founded in 1872, during the 19th-century kauri gum and timber trade, it briefly had New Zealand's largest population. Dargarville was made a borough in 1908.

Lake Ototoa
Lake Rototoa (formerly Lake Ototoa) is located at the northern end of the south head of the Kaipara Harbour in the Rodney ward of the Auckland Region, New Zealand. With a surface area of 1.39 km2 and a maximum depth of 26 m, it is the largest and deepest of a series of sand-dune lakes found along the western coastline of the North Island. Its name was changed from ''Lake Ototoa'' to ''Lake Rototoa'' in 2013. Rototoa translates as 'Lake of the Warrior', and is part of a line of lakes known as 'the Footsteps of Kawharu' after the warrior Kawharu who fought with the Ngāti Whātua tribe against the resident Waiohua, Ngaririki and Kawerau tribes in the late 17th to early 18th centuries.http://teaohou.natlib.govt.nz/journals/teaohou/issue/Mao40TeA/c19.html Biodiversity The lake is an important wildlife habitat for a number of New Zealand bird species, including the New Zealand grebe, New Zealand scaup and grey duck. The lake is vegetated with ''Typha orientalis'' and '' El ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaipara Harbour
Kaipara Harbour is a large enclosed harbour estuary complex on the north western side of the North Island of New Zealand. The northern part of the harbour is administered by the Kaipara District and the southern part is administered by the Auckland Council. The local Māori tribe is Ngāti Whātua. By area, the Kaipara Harbour is one of the largest harbours in the world. It covers at high tide, with exposed as mudflats and sandflats at low tide.Heath, RA (1975) ''Stability of some New Zealand coastal inlets.'' New Zealand Journal of Marine and Freshwater Research, 9 (4):449-57. According to Māori tradition, the name Kaipara had its origins back in the 15th century when the Arawa chief, Kahumatamomoe, travelled to the Kaipara to visit his nephew at Pouto. At a feast, he was so impressed with the cooked root of the para fern, that he gave the name Kai-para to the district. ''Kaipara'' comes from the Māori meaning "food", and meaning "king fern".

Endemic Freshwater Fish Of New Zealand
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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Bob McDowall
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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
