Powelliphanta
''Powelliphanta'' is a genus of large, air-breathing land snails, pulmonate gastropods in the family Rhytididae, found only in New Zealand. They are carnivorous, eating invertebrates, mostly native earthworms. Often restricted to very small areas of moist forest, they are prey to introduced mammalian predators, and many species are threatened or endangered. Taxonomy ''Powelliphanta'' was originally described by A. C. O'Connor in 1945 as a subgenus of the kauri snails, '' Paryphanta.'' They were named "in recognition of the great service rendered to the study of the family by Mr A. W. B. Powell", and from their similarity to ''Paryphanta''. In 1977 Climo raised ''Powelliphanta'' to genus rank, retaining just two species in ''Paryphanta''. There are at least 21 species and 51 subspecies within the genus. The relationship between the species is complex, and it has been suggested that the group ''Powelliphanta gilliesi-traversi-hochstetteri-rossiana-lignaria-superba'' forms ...

Body Whorl
The body whorl is part of the morphology of the shell in those gastropod mollusks that possess a coiled shell. The term is also sometimes used in a similar way to describe the shell of a cephalopod mollusk. In gastropods In gastropods, the body whorl, or last whorl, is the most recently formed and largest whorl (or revolution) of a spiral or helical shell, terminating in the aperture. It is called the "body whorl" because most of the body of the soft parts of the animal fits into this whorl. The proportional size of the body whorl in gastropod shells differs greatly according to the actual shell morphology. For shells in which the rate of whorl expansion of each revolution around the axis is very high, the aperture and the body whorl are large, and the shell tends to be low spired. The shell of the abalone is a good example of this kind of shell. The opposite tendency can sometimes create a high spire with very little whorl increase per revolution. In these instances, e.g. ...

Fiordland
Fiordland is a geographical region of New Zealand in the south-western corner of the South Island, comprising the westernmost third of Southland. Most of Fiordland is dominated by the steep sides of the snow-capped Southern Alps, deep lakes, and its steep, glacier-carved and now ocean-flooded western valleys. The name "Fiordland" comes from a variant spelling of the Scandinavian word for this type of steep valley, "fjord". The area of Fiordland is dominated by, and very roughly coterminous with, Fiordland National Park, New Zealand's largest National Park. Due to the often steep terrain and high amount of rainfall supporting dense vegetation, the interior of the Fiordland region is largely inaccessible. As a result, Fiordland was never subjected to notable logging operations, and even attempts at whaling, seal hunting, and mining were on a small scale and short-lived, partly also because of the challenging weather. Today, Fiordland contains by far the greatest extent of u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marlborough Sounds
The Marlborough Sounds are an extensive network of sea-drowned valleys at the northern end of the South Island of New Zealand. The Marlborough Sounds were created by a combination of land subsidence and rising sea levels. According to Māori mythology, the sounds are the prows of the many sunken waka of Aoraki. Overview Covering some of sounds, islands, and peninsulas, the Marlborough Sounds lie at the South Island's north-easternmost point, between Tasman Bay / Te Tai-o-Aorere in the west and Cloudy Bay in the south-east. The almost fractal coastline has 1/10 of the length of New Zealand's coasts. The steep, wooded hills and small quiet bays of the sounds are sparsely populated, as access is difficult. Many of the small settlements and isolated houses are only accessible by boat. The main large port is Picton on the mainland, at the head of Queen Charlotte Sound. It is at the northern terminus of the South Island's main railway and state highway networks. The main small-bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Island
The South Island, also officially named , is the larger of the two major islands of New Zealand in surface area, the other being the smaller but more populous North Island. It is bordered to the north by Cook Strait, to the west by the Tasman Sea, and to the south and east by the Pacific Ocean. The South Island covers , making it the world's 12th-largest island. At low altitude, it has an oceanic climate. The South Island is shaped by the Southern Alps which run along it from north to south. They include New Zealand's highest peak, Aoraki / Mount Cook at . The high Kaikōura Ranges lie to the northeast. The east side of the island is home to the Canterbury Plains while the West Coast is famous for its rough coastlines such as Fiordland, a very high proportion of native bush and national parks, and the Fox and Franz Josef Glaciers. The main centres are Christchurch and Dunedin. The economy relies on agriculture and fishing, tourism, and general manufacturing and services. ...

Lake Waikaremoana
Lake Waikaremoana is located in Te Urewera in the North Island of New Zealand, 60 kilometres northwest of Wairoa and 80 kilometres west-southwest of Gisborne. It covers an area of . From the Maori Waikaremoana translates as 'sea of rippling waters'. The lake lies in the heart of Tuhoe country. The hamlet of Aniwaniwa and the Waikaremoana Holiday Park are located on the lakeshore, along SH38 (from Wai-O-Tapu via Murupara to Wairoa), which connects the lake to the central North Island (Rotorua) and Gisborne. There is a Department of Conservation office at Aniwaniwa. Several walks start here, including a short stroll to Aniwaniwa Falls.

Endemic (ecology)
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 to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ring Species
In biology, a ring species is a connected series of neighbouring populations, each of which interbreeds with closely sited related populations, but for which there exist at least two "end" populations in the series, which are too distantly related to interbreed, though there is a potential gene flow between each "linked" population and the next. Such non-breeding, though genetically connected, "end" populations may co-exist in the same region ( sympatry) thus closing a "ring". The German term , meaning a circle of races, is also used. Ring species represent speciation and have been cited as evidence of evolution. They illustrate what happens over time as populations genetically diverge, specifically because they represent, in living populations, what normally happens over time between long-deceased ancestor populations and living populations, in which the intermediates have become extinct. The evolutionary biologist Richard Dawkins remarks that ring species "are only showing us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
