Fuscospora Truncata
''Nothofagus truncata'', or hard beech ( mi, tawhai raunui), is a species of tree endemic to New Zealand. Its common name derives from the fact that the timber has a high silica content, making it tough and difficult to saw.John Dawson and R. Lucas. 2000 Hard beech is a tree up to 30m tall occurring in lowland and lower montane forest from latitude 35°S to 42°30'S, that is, from the north of the North Island southwards to Marlborough and south Westland in the South Island.C. Michael Hogan. 2009 In Taranaki it forms almost pure stands on the rugged sandstone country there and is partially deciduous, dropping many of its leaves at the end of the winter.''Fuscospora truncata'' (Hard Beech) TERRAIN ''N. truncata'' became known as ''Fuscospora truncata'' after 2013 in ...

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 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silica
Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula , most commonly found in nature as quartz and in various living organisms. In many parts of the world, silica is the major constituent of sand. Silica is one of the most complex and most abundant families of materials, existing as a compound of several minerals and as a synthetic product. Notable examples include fused quartz, fumed silica, silica gel, opal and aerogels. It is used in structural materials, microelectronics (as an Insulator (electricity), electrical insulator), and as components in the food and pharmaceutical industries. Structure In the majority of silicates, the silicon atom shows tetrahedral coordination geometry, tetrahedral coordination, with four oxygen atoms surrounding a central Si atomsee 3-D Unit Cell. Thus, SiO2 forms 3-dimensional network solids in which each silicon atom is covalently bonded in a tetrahedral manner to 4 oxygen atoms. In contrast, CO2 is a linear ...

North Island
The North Island, also officially named Te Ika-a-Māui, is one of the two main islands of New Zealand, separated from the larger but much less populous South Island by the Cook Strait. The island's area is , making it the world's 14th-largest island. The world's 28th-most-populous island, Te Ika-a-Māui has a population of accounting for approximately % of the total residents of New Zealand. Twelve main urban areas (half of them officially cities) are in the North Island. From north to south, they are Whangārei, Auckland, Hamilton, Tauranga, Rotorua, Gisborne, New Plymouth, Napier, Hastings, Whanganui, Palmerston North, and New Zealand's capital city Wellington, which is located at the south-west tip of the island. Naming and usage Although the island has been known as the North Island for many years, in 2009 the New Zealand Geographic Board found that, along with the South Island, the North Island had no official name.

Westland District
Westland District is a Districts of New Zealand, territorial authority district on the West Coast, New Zealand, West Coast of New Zealand's South Island. It is administered by the Westland District Council. The district's population is History Westland was originally a part of Canterbury Province, administered from Christchurch in the East coast. The booming population as a result of the gold rush, together with the difficulty of travel and communication across the Southern Alps, led first to the creation of a special Westland County, then the formal separation of Westland from Canterbury to form the short-lived Westland Province (1873–1876). Westland Province also included what is now the southern portion of Grey District with the provincial boundary at the Grey River (New Zealand), Grey and Arnold River (New Zealand), Arnold rivers. Greymouth proper was in Westland Province, Cobden, New Zealand, Cobden, on the north bank of the Grey River, was in Nelson Province . After the ...

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. ...

Taranaki
Taranaki is a region in the west of New Zealand's North Island. It is named after its main geographical feature, the stratovolcano of Mount Taranaki, also known as Mount Egmont. The main centre is the city of New Plymouth. The New Plymouth District is home to more than 65 per cent of the population of Taranaki. New Plymouth is in North Taranaki along with Inglewood and Waitara. South Taranaki towns include Hāwera, Stratford, Eltham, and Ōpunake. Since 2005, Taranaki has used the promotional brand "Like no other". Geography Taranaki is on the west coast of the North Island, surrounding the volcanic peak of Mount Taranaki. The region covers an area of 7258 km2. Its large bays north-west and south-west of Cape Egmont are North Taranaki Bight and South Taranaki Bight. Mount Taranaki is the second highest mountain in the North Island, and the dominant geographical feature of the region.

Understorey
In forestry and ecology, understory (American English), or understorey (Commonwealth English), also known as underbrush or undergrowth, includes plant life growing beneath the forest canopy without penetrating it to any great extent, but above the forest floor. Only a small percentage of light penetrates the canopy so understory vegetation is generally shade-tolerant. The understory typically consists of trees stunted through lack of light, other small trees with low light requirements, saplings, shrubs, vines and undergrowth. Small trees such as holly and dogwood are understory specialists. In temperate deciduous forests, many understory plants start into growth earlier in the year than the canopy trees, to make use of the greater availability of light at that particular time of year. A gap in the canopy caused by the death of a tree stimulates the potential emergent trees into competitive growth as they grow upwards to fill the gap. These trees tend to have straight trunks ...

Crown Fern
''Lomaria discolor'', synonym ''Blechnum discolor'', commonly called crown fern (Māori: piupiu), is a species of fern in the family Blechnaceae. This species is endemic to New Zealand New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island count .... As noted by C. Michael Hogan, this species is found in a number of forest communities in diverse locations within New Zealand, and is sometimes a dominant understory component. Spores are produced on specialised fronds. These are more erect, with a dark and shrivelled look.Andrew Crowe (1994). ''Which Native Fern?'', p. 39. Auckland: Viking. . References * C.

Tannin
Tannins (or tannoids) are a class of astringent, polyphenolic biomolecules that bind to and precipitate proteins and various other organic compounds including amino acids and alkaloids. The term ''tannin'' (from Anglo-Norman ''tanner'', from Medieval Latin ''tannāre'', from ''tannum'', oak bark) refers to the use of oak and other bark in tanning animal hides into leather. By extension, the term ''tannin'' is widely applied to any large polyphenolic compound containing sufficient hydroxyls and other suitable groups (such as carboxyls) to form strong complexes with various macromolecules. The tannin compounds are widely distributed in many species of plants, where they play a role in protection from predation (acting as pesticides) and might help in regulating plant growth. The astringency from the tannins is what causes the dry and puckery feeling in the mouth following the consumption of unripened fruit, red wine or tea. Likewise, the destruction or modification of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nothofagus Solandri
''Nothofagus solandri'' var. ''solandri'', commonly called black beech, is a variety of the tree species ''Nothofagus solandri'', endemic to New Zealand. Black beech occurs on both the North and the South Island at low altitudes up to the mountains. The other variety of ''N. solandri'' is called mountain beech or ''Nothofagus solandri'' var. ''cliffortioides'', and grows at higher altitudes than black beech. In New Zealand the taxon is called ''Fuscospora solandri''. Black beech is a medium-sized evergreen tree growing to 27 m tall. The leaves are oppositely arranged, ovoid, 10 mm long and 5 mm broad, with smooth margins. Black beech is known as black beech because it is prone to a sooty mold which covers the trunk and branches. This, in turn, is the result of a scale insect which sucks sap from the tree, and excretes honeydew, a sweet liquid, in small droplets (less than 1 mm diameter) on the end of stalks. This feeds the sooty mold, and also forms a valuable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
