Northland Tusked Wētā
The Northland tusked wētā, ''Anisoura nicobarica'', is a rare monotypic wētā of the family Anostostomatidae, endemic to the northern half of Northland in New Zealand, and originally described in 1932. The type specimen was wrongly labelled as coming from the Nicobar Islands, so the species was named ''Anisoura nicobarica''. It was erroneously described again in 1950 by a different author, who placed it in the ground wētā genus ''Hemiandrus'' (as ''Hemiandrus monstrosus)''. Description Tusked wētā are distinctive because of the long curved "tusks" adult males have projecting forward from their jaws. The tusks are not used for biting but are used to push an opponent. Among the three species of tusked wētā, the Northland tusked wētā, ''Anisoura nicobarica,'' is the smallest measuring up to 21mm in body length. The Middle Island tusked wētā, ''Motuweta isolata,'' being the biggest measuring up to 70 mm in body length and the Raukumara tusked wētā, ''Motuweta ...

Arboreal Locomotion
Arboreal locomotion is the locomotion of animals in trees. In habitats in which trees are present, animals have evolved to move in them. Some animals may scale trees only occasionally, but others are exclusively arboreal. The habitats pose numerous mechanical challenges to animals moving through them and lead to a variety of anatomical, behavioral and ecological consequences as well as variations throughout different species.Cartmill, M. (1985). Climbing. In ''Functional Vertebrate Morphology'', eds. M. Hildebrand D. M. Bramble K. F. Liem and D. B. Wake, pp. 73–88. Cambridge: Belknap Press. Furthermore, many of these same principles may be applied to climbing without trees, such as on rock piles or mountains. Some animals are exclusively arboreal in habitat, such as the tree snail. Biomechanics Arboreal habitats pose numerous mechanical challenges to animals moving in them, which have been solved in diverse ways. These challenges include moving on narrow branches, mov ...

Orthoptera Genera
Orthoptera () is an order of insects that comprises the grasshoppers, locusts, and crickets, including closely related insects, such as the bush crickets or katydids and wētā. The order is subdivided into two suborders: Caelifera – grasshoppers, locusts, and close relatives; and Ensifera – crickets and close relatives. More than 20,000 species are distributed worldwide. The insects in the order have incomplete metamorphosis, and produce sound (known as a "stridulation") by rubbing their wings against each other or their legs, the wings or legs containing rows of corrugated bumps. The tympanum, or ear, is located in the front tibia in crickets, mole crickets, and bush crickets or katydids, and on the first abdominal segment in the grasshoppers and locusts. These organisms use vibrations to locate other individuals. Grasshoppers and other orthopterans are able to fold their wings (i.e. they are members of Neoptera). Etymology The name is derived from the Greek ὀρθό ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Zealand Threat Classification System
The New Zealand Threat Classification System is used by the Department of Conservation to assess conservation priorities of species in New Zealand. The system was developed because the IUCN Red List, a similar conservation status system, had some shortcomings for the unique requirements of conservation ranking in New Zealand. plants, animals, and fungi are evaluated, though the lattermost has yet to be published. Algae were assessed in 2005 but not reassessed since. Other protists have not been evaluated. Categories Species that are ranked are assigned categories: ;Threatened This category has three major divisions: ::*Nationally Critical - equivalent to the IUCN category of Critically endangered ::*Nationally Endangered - equivalent to the IUCN category of Endangered ::*Nationally Vulnerable - equivalent to the IUCN category of Vulnerable ;At Risk This has four categories: ::*Declining ::*Recovering ::*Relict ::*Naturally Uncommon ;Other categories ;;Introduced and Natur ...

Tree Wētā
Tree wētā are wētā in the genus ''Hemideina'' of the family Anostostomatidae. The genus is endemic to New Zealand. There are seven species within the genus ''Hemideina'', found throughout the country except lowland Otago and Southland. Because many tree wētā species are common and widespread they have been used extensively in studies of ecology and evolution. Habitat Tree wētā are commonly encountered in forests and suburban gardens throughout most of New Zealand. They are up to 40 mm long and most commonly live in holes in trees formed by beetle and moth larvae or where rot has set in after a twig has broken off. The hole, called a gallery, is maintained by the wētā and any growth of the bark surrounding the opening is chewed away. They readily occupy a preformed gallery in a piece of wood (a "wētā motel") and can be kept in a suburban garden as pets. A gallery might house a harem of up to 10 adult females and one male. Behaviour Tree wētā are nocturnal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hokianga
The Hokianga is an area surrounding the Hokianga Harbour, also known as the Hokianga River, a long estuarine drowned valley on the west coast in the north of the North Island of New Zealand. The original name, still used by local Māori, is ''Te Kohanga o Te Tai Tokerau'' ("the nest of the northern people") or ''Te Puna o Te Ao Marama'' ("the wellspring of moonlight"). The full name of the harbour is Te Hokianga-nui-a-Kupe — "the place of Kupe's great return". Geography The Hokianga is in the Far North District, which is in the Northland Region. The area is northwest of Whangarei—and west of Kaikohe—by road. The estuary extends inland for from the Tasman Sea. It is navigable for small craft for much of its length, although there is a bar across the mouth. In its upper reaches the Rangiora Narrows separate the mouths of the Waihou and Mangamuka Rivers from the lower parts of the harbour. 12,000 years ago, the Hokianga was a river valley flanked by steep bu ...

Bay Of Islands
The Bay of Islands is an area on the east coast of the Far North District of the North Island of New Zealand. It is one of the most popular fishing, sailing and tourist destinations in the country, and has been renowned internationally for its big-game fishing since American author Zane Grey publicised it in the 1930s. It is north-west of the city of Whangarei. Cape Reinga, at the northern tip of the country, is about by road further to the north-west. Geography The bay itself is an irregularly-shaped -wide, drowned valley system and a natural harbour. It contains 144 islands, of which the largest is Urupukapuka, and numerous peninsulas and inlets. The three largest inlets are Waikare Inlet in the south, and Kerikeri and Te Puna (Mangonui) inlets in the north-west. The Purerua Peninsula, north of Te Puna Inlet, separates the north-western part of the bay from the Pacific Ocean, and Cape Brett Peninsula extends into the ocean at the eastern end of the bay. The biggest t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leptospermum Scoparium
''Leptospermum scoparium'', commonly called mānuka, () mānuka myrtle, New Zealand teatree, broom tea-tree, or just tea tree, is a species of flowering plant in the myrtle family Myrtaceae, native to New Zealand (including the Chatham Islands) and south-east Australia. Its nectar produces Mānuka honey. Description Mānuka is a prolific shrub-type tree and is often one of the first species to regenerate on cleared land. It is typically a shrub growing to tall, but can grow into a moderately sized tree, up to or so in height. It is evergreen, with dense branching and small leaves long and broad, with a short spine tip. The flowers are white, occasionally pink, – rarely up to – in diameter, with five petals. The wood is tough and hard. Mānuka is often confused with the related species kānuka (''Kunzea ericoides'') – the easiest way to tell the difference between the two species in the field is to feel their foliage – mānuka leaves are prickly, while kānuka lea ...

Mercury Islands Tusked Wētā
The Mercury Islands tusked wētā, ''Motuweta isolata,'' also known as the Middle Island tusked wētā, is a large flightless insect in the family Anostostomatidae, discovered in 1970 living on a single small island in New Zealand. Distinguished by the enormous tusks with which males fight, it was saved from extinction by a captive breeding programme and translocation: the entire world population is descended from a male and two females captured and bred in captivity in 1998, just before the species went extinct in the wild. ''Motuweta isolata'' is the largest of the three tusked wētā species, and the most endangered wētā, ranked Nationally Critical by the Department of Conservation. Taxonomy ''Motuweta isolata'' was discovered in 1970 on Middle Island (Atiu in Māori) in the Mercury Islands group by herpetologist Tony Whitaker, and was nicknamed "Jaws". It was 15 years before more specimens were collected for research, and another 12 years before the species was finally d ...
