Norfolk Parakeet
The Norfolk parakeet (''Cyanoramphus cookii''), also called Tasman parakeet, Norfolk Island green parrot or Norfolk Island red-crowned parakeet, is a species of parrot in the family Psittaculidae. It is endemic to Norfolk Island (located between Australia, New Zealand and New Caledonia in the Tasman Sea). Taxonomy George Robert Gray described the Norfolk parakeet in 1859 as ''Platycercus Cookii'', from a specimen in William Bullock's museum, and recorded it as from New Zealand. The species name honours James Cook, who reported the species on Norfolk Island when he landed there in 1774, noting it was the same as those occurring in New Zealand. In 1862, Gray described a specimen from Norfolk Island as ''Platycercus rayneri'', collected by a Mr Rayner. In 1891, Italian ornithologist Tommaso Salvadori confirmed the two taxa as synonymous and coming from Norfolk Island. It was long considered a subspecies of the red-crowned parakeet of New Zealand.

Norfolk Island
Norfolk Island (, ; Norfuk: ''Norf'k Ailen'') is an external territory of Australia located in the Pacific Ocean between New Zealand and New Caledonia, directly east of Australia's Evans Head and about from Lord Howe Island. Together with the neighbouring Phillip Island and Nepean Island, the three islands collectively form the Territory of Norfolk Island. At the 2021 census, it had inhabitants living on a total area of about . Its capital is Kingston. The first known settlers in Norfolk Island were East Polynesians but they had already departed when Great Britain settled it as part of its 1788 settlement of Australia. The island served as a convict penal settlement from 6 March 1788 until 5 May 1855, except for an 11-year hiatus between 15 February 1814 and 6 June 1825, when it lay abandoned. On 8 June 1856, permanent civilian residence on the island began when descendants of the ''Bounty'' mutineers were relocated from Pitcairn Island. In 1914 the UK handed No ...

Alfred John North
Alfred John North (11 June 1855 – 6 May 1917) was an Australian ornithologist. North was born in Melbourne and was educated at Melbourne Grammar School. He was appointed to the Australian Museum, Sydney in 1886 and was given a permanent position there five years later. He wrote a ''List of the Insectivorous Birds of New South Wales'' (1897) and a ''Descriptive Catalogue of the Nests and Eggs of Birds Found Breeding in Australia and Tasmania'' (1889) with George Barnard as co-author. He described a number of birds for the first time, many in the ''Victorian Naturalist'', the magazine of the Field Naturalists Club of Victoria of which he was a founding member. ReferencesNorth, Alfred John (1855 - 1917)at Bright Sparcs, University of Melbourne The University of Melbourne is a public research university located in Melbourne, Australia.

Dodonaea Viscosa
''Dodonaea viscosa'', also known as the broadleaf hopbush, is a species of flowering plant in the '' Dodonaea'' (hopbush) genus that has a cosmopolitan distribution in tropical, subtropical and warm temperate regions of Africa, the Americas, southern Asia and Australasia. ''Dodonaea'' is part of Sapindaceae, the soapberry family. This species is notable for its extremely wide distribution, which it achieved only over the last 2 million years (from its region of origin in Australia) via oceanic dispersal. Harrington and Gadek (2009) referred to ''D. viscosa'' as having "a distribution equal to some world’s greatest transoceanic dispersers". Common names The common name hopbush is used for ''D. viscosa'' specifically and also for the genus as a whole. In the south Indian state of Tamil Nadu, this plant is called ''virāli'' (விராலி). Australian common names include: broad leaf hopbush, candlewood, giant hopbush, narrow leaf hopbush, sticky hopbush, native hop bush, ...

Rhopalostylis Baueri
''Rhopalostylis baueri'' is a species of palm native to Norfolk Island ( Australia) and to the Kermadec Islands (New Zealand). Norfolk Island is the type locality. The common names on Norfolk Island are 'Norfolk Island palm' or 'niau'. In New Zealand the name 'Kermadec nikau' is used to refer to the Kermadec Islands population.The palms native to Raoul Island in the Kermadecs, formerly described either as ''Rhopalostylis cheesemanii'' or ''R. baueri'' var. ''cheesemanii'', were relegated to synonymy with the Norfolk Island ''R. baueri'' in 2005 after comparison showed no significant distinguishing characteristics (de Lange et al., 2005). Distribution On Norfolk Island it now occupies a small range in the centre of the island near the national park, where the species is somewhat threatened by rats that eat the fruit and young seedlings. It is rare elsewhere on the island. In the Kermadec Islands part of its range it is not threatened, but it only occurs on Raoul Island. Following ...

Araucaria Heterophylla
''Araucaria heterophylla'' (synonym ''A. excelsa'') is a species of conifer. As its vernacular name Norfolk Island pine (or Norfolk pine) implies, the tree is endemic to Norfolk Island, an external territory of Australia located in the Pacific Ocean between New Zealand and New Caledonia. It is not a true pine, which belong to the genus ''Pinus'' in the family Pinaceae, but instead is a member of the genus ''Araucaria,'' in the family Araucariaceae, which also contains the monkey-puzzle tree. Members of ''Araucaria'' occur across the South Pacific, especially concentrated in New Caledonia (about due north of Norfolk Island) where 13 closely related and similar-appearing species are found. It is sometimes called a star pine, Polynesian pine, triangle tree or living Christmas tree, due to its symmetrical shape as a sapling. History The first European known to have sighted Norfolk Island was Captain James Cook. In 1774, on his second voyage to the South Pacific in HMS ''Resolut ...

Plantation
A plantation is an agricultural estate, generally centered on a plantation house, meant for farming that specializes in cash crops, usually mainly planted with a single crop, with perhaps ancillary areas for vegetables for eating and so on. The crops that are grown include cotton, coffee, tea, cocoa, sugar cane, opium, sisal, oil seeds, oil palms, fruits, rubber trees and forest trees. Protectionist policies and natural comparative advantage have sometimes contributed to determining where plantations are located. In modern use the term is usually taken to refer only to large-scale estates, but in earlier periods, before about 1800, it was the usual term for a farm of any size in the southern parts of British North America, with, as Noah Webster noted, "farm" becoming the usual term from about Maryland northwards. It was used in most British colonies, but very rarely in the United Kingdom itself in this sense. There, as also in America, it was used mainly for tree plantati ...

Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lord Howe Red-crowned Parakeet
The Lord Howe parakeet (''Cyanoramphus subflavescens''), also known as the Lord Howe red-fronted parakeet, is an extinct parrot endemic to Lord Howe Island in the Tasman Sea, part of New South Wales, Australia. It was described as full species by Tommaso Salvadori in 1891, but subsequently it has been regarded as subspecies of the red-crowned parakeet. In 2012, the IOC World Bird List recognised it as species.IOC world birdnames Taxonomy Pending molecular analysis, Christidis & Boles (2008) have suggested on biogeographical grounds that the taxon is likely to be most closely related to the Norfolk Island green ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
