Strigopoidea
The New Zealand parrot family, Strigopidae,Nestoridae and Strigopidae are described in the same article, Bonaparte, C.L. (1849) ''Conspectus Systematis Ornithologiae''. Therefore, under rules of the ICZN, the first reviser determines priority, which is Bonaparte, C.L. (1850), ''Conspectus Generum Avium'', E.J. Brill, Leyden. consists of at least three genera of parrots – '' Nestor'', '' Strigops'', the fossil '' Nelepsittacus'', and probably the fossil ''Heracles''. The genus ''Nestor'' consists of the kea, kākā, Norfolk kākā and Chatham kākā, while the genus ''Strigops'' contains the iconic kākāpō. All extant species are endemic to New Zealand. The species of the genus ''Nelepsittacus'' were endemics of the main islands, while the two extinct species of the genus ''Nestor'' were found at the nearby oceanic islands such as Chatham Island of New Zealand, and Norfolk Island and adjacent Phillip Island. The Norfolk kaka and the Chatham kaka have become extinct in re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early Miocene
The Early Miocene (also known as Lower Miocene) is a sub-epoch of the Miocene Epoch made up of two stages: the Aquitanian and Burdigalian stages. The sub-epoch lasted from 23.03 ± 0.05 Ma to 15.97 ± 0.05 Ma (million years ago). It was preceded by the Oligocene epoch. As the climate started to get cooler, the landscape started to change. New mammals evolved to replace the extinct animals of the Oligocene epoch. The first members of the hyena and weasel family started to evolve to replace the extinct ''Hyaenodon'', entelodonts and bear-dogs. The chalicotheres survived the Oligocene epoch. A new genus of entelodont called ''Daeodon'' evolved in order to adapt to the new habitats and hunt the new prey animals of the Early Miocene epoch; it quickly became the top predator of North America. But it became extinct due to competition from '' Amphicyon'', a newcomer from Eurasia. ''Amphicyon'' bested ''Daeodon'' because the bear-dog Amphicyonidae is an extinct family of terrestr ...

Chatham Kākā
The Chatham kākā or Chatham Island kākā (''Nestor chathamensis'') is an extinct parrot species previously found on the Chatham Islands, New Zealand. The first individuals were thought to belong to the New Zealand kākā (''Nestor meridionalis''), but detailed examination of the subfossil bones showed that they actually belong to a separate endemic species. The species became extinct within the first 150 years of the arrival of the Polynesians around 1500, long before any European settlers. No skins or descriptions are available. Taxonomy The Chatham kākā is assigned to the genus ''Nestor'' in the family Nestoridae, a small group of parrot species native to New Zealand. It is considered to have been more closely related to the kākā (''Nestor meridionalis'') and the extinct Norfolk kākā (''Nestor productus'') than to the kea (''Nestor notabilis''). Ecology The Chatham kākā was a forest dwelling species of about the same size as the North Island subspecies of the kāk� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gondwana
Gondwana () was a large landmass, often referred to as a supercontinent, that formed during the late Neoproterozoic (about 550 million years ago) and began to break up during the Jurassic period (about 180 million years ago). The final stages of break-up, involving the separation of Antarctica from South America (forming the Drake Passage) and Australia, occurred during the Paleogene. Gondwana was not considered a supercontinent by the earliest definition, since the landmasses of Baltica, Laurentia, and Siberia were separated from it. To differentiate it from the Indian region of the same name (see ), it is also commonly called Gondwanaland. Gondwana was formed by the accretion of several cratons. Eventually, Gondwana became the largest piece of continental crust of the Palaeozoic Era, covering an area of about , about one-fifth of the Earth's surface. During the Carboniferous Period, it merged with Laurasia to form a larger supercontinent called Pangaea. Gondwana (and Pan ...

Wasp
A wasp is any insect of the narrow-waisted suborder Apocrita of the order Hymenoptera which is neither a bee nor an ant; this excludes the broad-waisted sawflies (Symphyta), which look somewhat like wasps, but are in a separate suborder. The wasps do not constitute a clade, a complete natural group with a single ancestor, as bees and ants are deeply nested within the wasps, having evolved from wasp ancestors. Wasps that are members of the clade Aculeata can Stinger, sting their prey. The most commonly known wasps, such as yellowjackets and hornets, are in the family Vespidae and are Eusociality, eusocial, living together in a nest with an egg-laying queen and non-reproducing workers. Eusociality is favoured by the unusual haplodiploid system of sex-determination system, sex determination in Hymenoptera, as it makes sisters exceptionally closely related to each other. However, the majority of wasp species are solitary, with each adult female living and breeding independently ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Common Brushtail Possum
The common brushtail possum (''Trichosurus vulpecula'', from the Greek for "furry tailed" and the Latin for "little fox", previously in the genus ''Phalangista'') is a nocturnal, semiarboreal marsupial of the family Phalangeridae, native to Australia and naturalised in New Zealand, and the second-largest of the possums. Like most possums, the common brushtail possum is nocturnal. It is mainly a folivore, but has been known to eat small mammals such as rats. In most Australian habitats, eucalyptus leaves are a significant part of the diet, but rarely the sole item eaten. Its tail is prehensile and naked on its lower underside. The four colour variations are silver-grey, brown, black, and gold. It is the Australian marsupial most often seen by city dwellers, as it is one of few that thrive in cities and a wide range of natural and human-modified environments. Around human habitations, common brushtails are inventive and determined foragers with a liking for fruit trees, vegetable g ...

Invasive Species In New Zealand
A number of introduced species, some of which have become invasive species, have been added to New Zealand's native flora and fauna. Both deliberate and accidental introductions have been made from the time of the first human settlement, with several waves of Polynesian people at some time before the year 1300, followed by Europeans after 1769. Almost without exception, the introduced species have been detrimental to the native flora and fauna but some, such as farmed sheep and cows and the clover upon which they feed, now form a large part of the economy of New Zealand. Registers, lists and indexes of species that are invasive, potentially invasive, or a threat to agriculture or biodiversity are maintained by Biosecurity New Zealand. Animal species Many invasive animal species are listed in schedules 5 and 6 of the Wildlife Act 1953. Those in Schedule 5 have no protection and may be killed. Those in Schedule 6 are declared to be noxious animals and subject to the Wild A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Norfolk Kaka
Norfolk () is a ceremonial and non-metropolitan county in East Anglia in England. It borders Lincolnshire to the north-west, Cambridgeshire to the west and south-west, and Suffolk to the south. Its northern and eastern boundaries are the North Sea, with The Wash to the north-west. The county town is the city of Norwich. With an area of and a population of 859,400, Norfolk is a largely rural county with a population density of 401 per square mile (155 per km2). Of the county's population, 40% live in four major built up areas: Norwich (213,000), Great Yarmouth (63,000), King's Lynn (46,000) and Thetford (25,000). The Broads is a network of rivers and lakes in the east of the county, extending south into Suffolk. The area is protected by the Broads Authority and has similar status to a national park. History The area that was to become Norfolk was settled in pre-Roman times, (there were Palaeolithic settlers as early as 950,000 years ago) with camps along the higher lan ...

Phillip Island (Norfolk Island)
Phillip Island is an island located south of Norfolk Island in the Southwest Pacific, and is part of the Norfolk Island group. It was named in 1788 by Lieutenant Philip Gidley King after Arthur Phillip, the first Governor of New South Wales. Phillip Island is part of the Australian external territory of Norfolk Island, and is included in Norfolk Island National Park, as is neighbouring Nepean Island and about 10 percent of Norfolk Island proper. A National Parks hut located near the centre of the island houses a small rotating group of around four people for much of the year. Otherwise the island is uninhabited. Phillip Island has an area of , measuring from west to east and from north to south, with the highest point, Jacky Jacky, being above sea level. It is roughly shaped like a hairdryer with the nozzle pointing east. The island is of volcanic origin, made of basaltic tuff and lava dating from the Miocene epoch. Phillip Island is included on the Register of the N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Norfo ...
