Otago Skink
The Otago skink (''Oligosoma otagense'') is a rare, endangered species of large skink in the family Scincidae, found in the rocky canyons and grassy patches of Central Otago, New Zealand. Physical characteristics Otago skinks are large compared to other New Zealand skinks, growing up to . They are marked with distinctive black, yellow, and green spots, which provides excellent camouflage in their rocky habitat of lichen-covered rocks and schist outcrops. Juveniles have more of a yellow base with dark blotches and shorter limbs. Like most skinks, Otago skinks are omnivores and feed on a wide variety of insects, fleshy fruits, flower petals, or even other small reptiles. They are long-lived, reaching around 16 years in the wild and up to 40 years in captivity, and are slow to mature, reaching sexual maturity at 3–4 years. Unlike many reptiles, this species is viviparous, with embryos developing in the mother's body, who then gives birth to live young. Between one and three yo ...

Charles McCann
Yule Mervyn Charles McCann (4 December 1899 – 29 November 1980) was a naturalist in India. He wrote a popular book on the trees of India and edited a major regional flora apart from publishing many of his other observations, mainly in the journal of the Bombay Natural History Society (BNHS) that he was associated with. Early life Born at Castle Rock in India, his exposure to the wilderness during his childhood in the forests of the Goa area shaped his lifelong interest in natural history: He studied at St. Mary's High school at Mazagaon in Bombay (now Mumbai) and worked for a while under Father Ethelbert Blatter at St. Xavier's College as a laboratory assistant and curator. During 1916-1920 he worked under Blatter on botany. He briefly worked with the Bombay city police and then joined the Bombay Natural History Society (BNHS) as a collector for the Mammal Survey. He worked on the survey around 1921-22 in the Palni Hills and also in the Indus delta areas. Career McCann ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Hāwea
Lake Hāwea is New Zealand's List of lakes in New Zealand#Largest lakes, ninth largest lake. The lake is in the Otago Region at an altitude of 348 metres. It covers 141 km² and reaches 392 metres deep. Lake Hāwea is named after a Māori people, Māori tribe who preceded the Waitaha (South Island iwi), Waitaha people in the area. Lake Hāwea stretches 35 kilometres from north to south. It lies in a U-shaped valley, glacial valley formed during the last ice age, and is fed by the Hunter River (New Zealand), Hunter River. Nearby Lake Wānaka lies in a parallel glacial valley eight kilometres to the west. At their closest point, a rocky ridge called The Neck, the lakes are only 1000 metres apart. Lake Hāwea is dammed to the south by an ancient terminal moraine created some 10,000 years ago. In 1958 the lake was artificially raised 20 metres to store more water for increased hydroelectric power generation at the Roxburgh Dam. The only flat land around the lake is at its s ...

Oligosoma
''Oligosoma'' is a genus of small to medium-sized skinks (family Scincidae) found only in New Zealand, Norfolk Island and Lord Howe Island. ''Oligosoma'' had previously been found to belong to the ''Eugongylus'' group of genera in the subfamily Lygosominae; the Australian genus ''Bassiana'' appears to be fairly closely related. Species The currently described species are: *'' Oligosoma acrinasum'' – Fiordland skink *'' Oligosoma aeneum'' – copper skink *'' Oligosoma alani'' – Alan's skink, robust skink *''Oligosoma albornense'' – Alborn skink *'' Oligosoma auroraense'' – Hawke's Bay skink, eastern speckled skink *'' Oligosoma awakopaka'' – Awakopaka skink *'' Oligosoma burganae'' – Burgan skink *'' Oligosoma chloronoton'' – green skink *'' Oligosoma elium'' – Marlborough spotted skink *'' Oligosoma fallai'' – Falla's skink, Three Kings skink *'' Oligosoma grande'' – grand skink *'' Oligosoma hardyi'' – Hardy's skink *'' Oligosoma homalonotum' ...

Functionally Extinct
Functional extinction is the extinction of a species or other taxon such that: #It disappears from the fossil record, or historic reports of its existence cease; #The reduced population no longer plays a significant role in ecosystem function; or #The population is no longer viable. There are no individuals able to reproduce, or the small population of breeding individuals will not be able to sustain itself due to inbreeding depression and genetic drift, which leads to a loss of fitness. In plant populations, self-incompatibility mechanisms may cause related plant specimens to be incompatible, which may lead to functional extinction if an entire population becomes self-incompatible. This does not occur in larger populations. In polygynous populations, where only a few males leave offspring, there is a much smaller reproducing population than if all viable males were considered. Furthermore, the successful males act as a genetic bottleneck, leading to more rapid genetic drift or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
In Situ Conservation
''In-situ'' conservation is the on-site conservation or the conservation of genetic resources in natural populations of plant or animal species, such as forest genetic resources in natural populations of Teagan species. This process protects the inhabitants and ensures the sustainability of the environment and ecosystem. Methods About 4% of the total geographical area of the country is used for ''in situ'' conservation. The following methods are presently used for ''in situ'' conservation. Biosphere reserve Biosphere reserves cover very large areas, often more than 5000 km2. They are used to protect species for a long time. Currently, there are 18 Biosphere Reserves in India. National parks A national park is an area dedicated for the conservation of wildlife along with its environment. A national park is an area which is used to conserve scenery, natural and historical objects. It is usually a small reserve covering an area of about 100 to 500 square kilometers. Within ...

Habitat Conservation
Habitat conservation is a management practice that seeks to conserve, protect and restore habitats and prevent species extinction, fragmentation or reduction in range. It is a priority of many groups that cannot be easily characterized in terms of any one ideology. History of the conservation movement For much of human history, ''nature'' was seen as a resource that could be controlled by the government and used for personal and economic gain. The idea was that plants only existed to feed animals and animals only existed to feed humans. The value of land was limited only to the resources it provided such as fertile soil, timber, and minerals. Throughout the 18th and 19th centuries, social views started to change and conservation principles were first practically applied to the forests of British India. The conservation ethic that began to evolve included three core principles: 1) human activities damage the environment, 2) there was a civic duty to maintain the environment ...

Predator Control
Hunting is the human practice of seeking, pursuing, capturing, or killing wildlife or feral animals. The most common reasons for humans to hunt are to harvest food (i.e. meat) and useful animal products (fur/ hide, bone/tusks, horn/ antler, etc.), for recreation/taxidermy (see trophy hunting), to remove predators dangerous to humans or domestic animals (e.g. wolf hunting), to eliminate pests and nuisance animals that damage crops/livestock/poultry or spread diseases (see varminting), for trade/tourism (see safari), or for ecological conservation against overpopulation and invasive species. Recreationally hunted species are generally referred to as the '' game'', and are usually mammals and birds. A person participating in a hunt is a hunter or (less commonly) huntsman; a natural area used for hunting is called a game reserve; an experienced hunter who helps organize a hunt and/or manage the game reserve is known as a gamekeeper. Many non-human animals also hunt (s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
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 ...

Department Of Conservation (New Zealand)
The Department of Conservation (DOC; Māori: ''Te Papa Atawhai'') is the public service department of New Zealand charged with the conservation of New Zealand's natural and historical heritage. An advisory body, the New Zealand Conservation Authority (NZCA) is provided to advise DOC and its ministers. In addition there are 15 conservation boards for different areas around the country that provide for interaction between DOC and the public. Function Overview The department was formed on 1 April 1987, as one of several reforms of the public service, when the ''Conservation Act 1987'' was passed to integrate some functions of the Department of Lands and Survey, the Forest Service and the Wildlife Service. This act also set out the majority of the department's responsibilities and roles. As a consequence of Conservation Act all Crown land in New Zealand designated for conservation and protection became managed by the Department of Conservation. This is about 30% of New Z ...
