Malherbe's Parakeet
Malherbe's parakeet (''Cyanoramphus malherbi''), usually known as the orange-fronted parakeet ( mi, kākāriki karaka), is a small parrot endemic to New Zealand.

Charles De Souancé
Charles de Souancé (2 May 1823 – 23 January 1896) was a French ornithologist and a purser in the French Navy, more precisely "Commissaire de la Marine". He made many studies on the ornithological collection of his uncle François Victor Masséna and described several new species of parrots (Psittacidae) in the scientific journal ''Revue et Magazin de Zoologie''. A subspecies of the maroon-tailed parakeet, ''Pyrrhura melanura souancei'', is named for him. Published works * ''Description de quelques nouvelles espèces d'oiseaux de la famille des psittacidés'', with François Victor Masséna, 1854 – Description of some new species of birds within the family Psittacidae. * ''Iconographie des perroquets, non figurés dans les publications de Levaillant et de M.

Fuscospora
''Nothofagus'', also known as the southern beeches, is a genus of 43 species of trees and shrubs native to the Southern Hemisphere in southern South America (Chile, Argentina) and Australasia (east and southeast Australia, New Zealand, New Guinea, and New Caledonia). The species are ecological dominants in many temperate forests in these regions. Some species are reportedly naturalised in Germany and Great Britain. The genus has a rich fossil record of leaves, cupules, and pollen, with fossils extending into the late Cretaceous period and occurring in Australia, New Zealand, Antarctica, and South America. Description The leaves are toothed or entire, evergreen or deciduous. The fruit is a small, flattened or triangular nut, borne in cupules containing one to seven nuts. Reproduction Many individual trees are extremely old, and at one time, some populations were thought to be unable to reproduce in present-day conditions where they were growing, except by suckering ( clonal ...

Habitat Fragmentation
Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (habitat), causing population fragmentation and ecosystem decay. Causes of habitat fragmentation include geological processes that slowly alter the layout of the physical environment (suspected of being one of the major causes of speciation), and human activity such as land conversion, which can alter the environment much faster and causes the extinction of many species. More specifically, habitat fragmentation is a process by which large and contiguous habitats get divided into smaller, isolated patches of habitats. Definition The term habitat fragmentation includes five discrete phenomena: * Reduction in the total area of the habitat * Decrease of the interior: edge ratio * Isolation of one habitat fragment from other areas of habitat * Breaking up of one patch of habitat into several smaller patches * Decrease in the average size of each patch of hab ...

Habitat Destruction
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wide ...

Pinus Radiata
''Pinus radiata'' ( syn. ''Pinus insignis''), the Monterey pine, insignis pine or radiata pine, is a species of pine native to the Central Coast of California and Mexico ( Guadalupe Island and Cedros island). It is an evergreen conifer in the family Pinaceae. ''P. radiata'' is a versatile, fast-growing, medium-density softwood, suitable for a wide range of uses. Its silviculture reflects a century of research, observation and practice. It is often considered a model for growers of other plantation species. It is the most widely planted pine in the world, valued for rapid growth and desirable lumber and pulp qualities. Although ''P. radiata'' is extensively cultivated as a plantation timber in many temperate parts of the world, it faces serious threats in its natural range, due to the introduction of pine pitch canker (''Fusarium circinatum''). Description ''P. radiata'' is a coniferous evergreen tree growing to tall in the wild, but up to in cultivation in optimum condi ...

Fuscospora Fusca
''Nothofagus fusca'', commonly known as red beech (Māori: tawhai raunui) is a species of southern beech, endemic to New Zealand, where it occurs on both the North Island and South Island. Generally it is found on lower hills and inland valley floors where soil is fertile and well drained. In New Zealand the species is called ''Fuscospora fusca''. It is a medium-sized evergreen tree growing to 35 m tall. The leaves are alternately arranged, broad ovoid, 2 to 4 cm long and 1.5 to 3 cm broad, the margin distinctively double-toothed with each lobe bearing two teeth. The fruit is a small cupule containing three seeds. Pollen from the tree was found near the Antarctic Peninsula showing that it formerly grew in Antarctica since the Eocene period. Red beech is not currently considered threatened. Uses Red beech is the only known plant source, apart from rooibos (''Aspalathus linearis''), of the C-linked dihydrochalcone glycoside nothofagin. It is also grown as an or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blechnum Penna-marina
''Austroblechnum penna-marina'', synonym ''Blechnum penna-marina'', known as Antarctic hard-fern, alpine water fern and pinque (Chilean Spanish), is a species of fern in the family Blechnaceae, with a natural range from the Araucanía Region to the south and from the coast to the tree line of the Magellanic forests in Chile and adjacent areas of Argentina. It is also found in New Zealand, Australia and some Pacific islands. It is evergreen In botany, an evergreen is a plant which has foliage that remains green and functional through more than one growing season. This also pertains to plants that retain their foliage only in warm climates, and contrasts with deciduous plants, whic ... and grows to .

Leptinella Maniototo
''Leptinella'' is a genus of alpine flowering plant in the family Asteraceae, comprising 33 species, distributed in New Guinea, Australia, New Zealand, South Africa, and South America. Many of the species are endemic to New Zealand. For over 100 years, ''Leptinella'' species were considered part of the genus ''Cotula'', but the genus ''Leptinella'' was reinstated by Lloyd & Webb in 1987. They determined that all species of ''Leptinella'' are distinguished from those of the other two sections of ''Cotula'', and other Anthemideae, by the conspicuous "inflated" corollas of the female florets and by chromosome numbers based on x = 26 where known. ''Leptinella squalida'' 'Platt's Black' is a form cultivated as a garden plant, and is used for ground cover Groundcover or ground cover is any plant that grows over an area of ground. Groundcover provides protection of the topsoil from erosion and drought. In an ecosystem, the ground cover forms the layer of vegetation below the shru ...
