Asplenium Hookerianum
''Asplenium hookerianum'', commonly known as Hooker's spleenwort, rocklax and maidenhair fern, is a small fern native to New Zealand and Australia. Description This small fern may be found two forms. The ''broad-pinnuled'' version's fronds have rounded ultimate segments while the ''narrow-pinnuled'' version has very fine and narrow ultimate segments. Distribution ''Asplenium hookerianum'' is found in New Zealand (including the Chatham Islands) and Australia. New Zealand Found throughout the North and South Islands of New Zealand. Less common in Northland, inland Taranaki, western Waikato, King Country and the West Coast. Its range extends to Stewart Island and the Chatham Islands although it is uncommon. Occurs in lowland and montane forests, on shaded clay banks and rocky outcrops, in shrubland and open forest. May also be found among grass and in open pasture, under pine and macrocarpa trees, and in disturbed forest remnants. In the South Island, it is mostly co ...

William Colenso
William Colenso (17 November 1811 – 10 February 1899) FRS was a Cornish Christian missionary to New Zealand, and also a printer, botanist, explorer and politician. He attended the signing of the Treaty of Waitangi and later wrote an account of the events at Waitangi. Life Born in Penzance, Cornwall, he was the cousin of John William Colenso, bishop of Natal. His surname is locative and it originates from the place name Colenso in the parish of St Hilary, near Penzance in west Cornwall, it is a Cornish language (Celtic) name, from the Cornish "Kelyn dhu" meaning "dark hollies". He trained as a printer's apprentice then travelled to New Zealand in 1834 to work for the Church Missionary Society as a printer/missionary. He was responsible for the printing of the Māori language translation of the New Testament in 1837. It was the first book printed in New Zealand and the first indigenous language translation of the Bible published in the southern hemisphere. pp 110 By Jul ...

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. ...

Asplenium Bulbiferum
''Asplenium bulbiferum'', known as mother spleenwort, is a fern species native to New Zealand only. It is also called hen and chicken fern and, in the Māori language, pikopiko, mouku or mauku. Its fronds are eaten as a vegetable. It grows small bulbils on top of its fronds. Once grown to about , these offspring fall off and, provided the soil they land in is kept moist, develop a root system and grow into new ferns. This additional means of reproduction can be employed with greater ease than propagation by spores. There are a number of similar Southern Hemisphere species which have a similar mode of reproduction, including '' Asplenium daucifolium''. ''Asplenium bulbiferum'' commonly grows in most bush areas in New Zealand. It thrives in many situations from shade to partial sunlight. Similar species It is often confused with ''Asplenium gracillimum'' which is a fern species native to both New Zealand and Australia. ''A. gracillimum'' is the fertile allotetraploid P ...

Joseph Dalton Hooker
Sir Joseph Dalton Hooker (30 June 1817 – 10 December 1911) was a British botanist and explorer in the 19th century. He was a founder of geographical botany and Charles Darwin's closest friend. For twenty years he served as director of the Royal Botanical Gardens, Kew, succeeding his father, William Jackson Hooker, and was awarded the highest honours of British science. Biography Early years Hooker was born in Halesworth, Suffolk, England. He was the second son of the famous botanist Sir William Jackson Hooker, Regius Professor of Botany, and Maria Sarah Turner, eldest daughter of the banker Dawson Turner and sister-in-law of Francis Palgrave. From age seven, Hooker attended his father's lectures at Glasgow University, taking an early interest in plant distribution and the voyages of explorers like Captain James Cook. He was educated at the Glasgow High School and went on to study medicine at Glasgow University, graduating M.D. in 1839. This degree qualified him for ...

Homonym
In linguistics, homonyms are words which are homographs (words that share the same spelling, regardless of pronunciation), or homophones (equivocal words, that share the same pronunciation, regardless of spelling), or both. Using this definition, the words ''row'' (propel with oars), ''row'' (a linear arrangement) and ''row'' (an argument) are homonyms because they are homographs (though only the first two are homophones): so are the words ''see'' (vision) and ''sea'' (body of water), because they are homophones (though not homographs). A more restrictive and technical definition requires that homonyms be simultaneously homographs ''and'' homophoneshomonym ''Random House Unabridged Dictionary'' at dictionary.com – that is to say they have identical spelling ''and'' pronunciation, but with different meanings. Examples are the pair ''stalk'' ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

Overhang (rock Formation)
An overhang is a rock face or artificial climbing wall with a slope of more than 90°, i.e. it slopes beyond the vertical. Particularly severe overhangs that reach, or nearly reach, the horizontal, are referred to as a roof. In climbing, overhangs and especially roofs place special demands both in terms of technique and equipment as well as the constitution of the climber. With increasing steepness the loading on arm and hand muscles increases, because the feet can support less and less of the body weight. Rest points where the muscles can be relaxed, especially no-hands rests, are rarely found in overhangs. Climbing techniques to tackle overhangs include placing the body's centre of mass as close as possible to the rock and striving for the highest possible body tension. Many climbing techniques such as the foothook are almost exclusively used in overhangs and roofs. For a long time in Alpine climbing, roofs were almost always tacked using climbing aids. By contrast, in mo ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Rock-faces
In geography and geology, a cliff is an area of rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs. An escarpment (or scarp) is a type of cliff formed by the movement of a geologic fault, a landslide, or sometimes by rock slides or falling rocks which change the differential erosion of the rock layers. Most cliffs have some form of scree slope at their base. In arid areas or under high cliffs, they are generally exposed jumbles of fallen rock. In areas of higher moisture, a soil slope may obscure the talus. Many cliffs also featur ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Dicksonia Antarctica
''Dicksonia antarctica'', the soft tree fern or man fern, is a species of evergreen tree fern native to eastern Australia, ranging from south-east Queensland, coastal New South Wales and Victoria to Tasmania. Anatomy and biology These ferns can grow to in height, but more typically grow to about , and consist of an erect rhizome forming a trunk. They are very hairy at the base of the stipe (adjoining the trunk) and on the crown. The large, dark green, roughly-textured fronds spread in a canopy of in diameter. The shapes of the stems vary as some grow curved and there are multi-headed ones. The fronds are borne in flushes, with fertile and sterile fronds often in alternating layers. The "trunk" of this fern is merely the decaying remains of earlier growth of the plant and forms a medium through which the roots grow. The trunk is usually solitary, without runners, but may produce offsets. They can be cut down and, if they are kept moist, the top portions can be replanted and ...

Gully
A gully is a landform created by running water, mass movement, or commonly a combination of both eroding sharply into soil or other relatively erodible material, typically on a hillside or in river floodplains or terraces. Gullies resemble large ditches or small valleys, but are metres to tens of metres in depth and width and are characterised by a distinct 'headscarp' or 'headwall' and progress by headward (i.e. upstream) erosion. Gullies are commonly related to intermittent or ephemeral water flow usually associated with localised intense or protracted rainfall events, or snowmelt. Gullies can be formed and accelerated by cultivation practices on hillslopes (often gentle gradient) in farmland, and they can develop rapidly in rangelands from existing natural erosion forms subject to vegetative cover removal and livestock activity. Etymology The earliest known usage of the term is from 1657. It originates from the French word ''goulet'', a diminutive form of ''goule'' which m ...

Rainforest
Rainforests are characterized by a closed and continuous tree canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforest can be classified as tropical rainforest or temperate rainforest, but other types have been described. Estimates vary from 40% to 75% of all biotic species being indigenous to the rainforests. There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the " world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests as well as endemic rainforest species are rapidly disappearing due to deforestation, the resulting habitat loss and pollution of the atmosphere. Definition Rainforest are characterized by a closed and continuous tree canopy, high humidity, the presence of moisture-dependent vegetation, a moist layer of lea ...

Victoria (Australia)
Victoria is a state in southeastern Australia. It is the second-smallest state with a land area of , the second most populated state (after New South Wales) with a population of over 6.5 million, and the most densely populated state in Australia (28 per km2). Victoria is bordered by New South Wales to the north and South Australia to the west, and is bounded by the Bass Strait to the south (with the exception of a small land border with Tasmania located along Boundary Islet), the Great Australian Bight portion of the Southern Ocean to the southwest, and the Tasman Sea (a marginal sea of the South Pacific Ocean) to the southeast. The state encompasses a range of climates and geographical features from its temperate coastal and central regions to the Victorian Alps in the northeast and the semi-arid north-west. The majority of the Victorian population is concentrated in the central-south area surrounding Port Phillip Bay, and in particular within the metropolit ...
