Vitex Lucens
''Vitex lucens'', or pūriri, is an evergreen tree endemic to New Zealand. History Pūriri was first collected (by Europeans) at Tolaga Bay by Banks and Solander during Cook's first visit in 1769. The plant was excellently described by Solander in his manuscript "Primitae Florae Novae Zelandiae" under the name ''Ephielis pentaphylla'', and a drawing of considerable artistic merit was also prepared.Cheeseman (1914) Illustrations of the New Zealand Flora. Vol 2. The next botanist to notice pūriri, Allan Cunningham, did not do so until 1826 when he observed it on "the rocky shores of Bay of Islands, growing frequently within the range of salt water." Cunningham named it ''Vitex littoralis'', correctly assigning it to the genus ''Vitex'' but overlooking that "littoralis" had been used for a Malayan species 4 years earlier. Thomas Kirk proposed ''V. lucens'' in 1897 after attention had been drawn to the fact that ''V. littoralis'' was taken.A.C. Dijkgraaf (1994) Propagation and ...

Thames, New Zealand
Thames () ( mi, Pārāwai) is a town at the southwestern end of the Coromandel Peninsula in New Zealand's North Island. It is located on the Firth of Thames close to the mouth of the Waihou River. The town is the seat of the Thames-Coromandel District Council. The Māori iwi are Ngāti Maru, who are descendants of Marutuahu's son Te Ngako. Ngāti Maru is part of the Ngati Marutuahu confederation of tribes or better known as Hauraki Iwi. Thames had an estimated population of 15,000 in 1870, but this declined to 4,500 in 1881, and it has increased modestly since. It is still the biggest town on the Coromandel. Until 2016, a historical oak tree that was planted by Governor George Grey stood on the corner of Grey and Rolleston streets. Demographics Thames covers and had an estimated population of as of with a population density of people per km2. Thames had a population of 7,293 at the 2018 New Zealand census, an increase of 342 people (4.9%) since the 2013 census, and a ...

Tiritiri Matangi Island
Tiritiri Matangi Island is located in the Hauraki Gulf of New Zealand, east of the Whangaparaoa Peninsula in the North Island and north east of Auckland. The island is an open nature reserve managed by the Supporters of Tiritiri Matangi Incorporated, under the supervision of the Department of Conservation and is noted for its bird life, including takahē, North Island kōkako and kiwi. It attracts between 30,000 and 32,000 visitors a year, the latter figure being the maximum allowed by the Auckland Conservation Management Strategy. The name, Māori for "tossed by the wind", is often popularly shortened to Tiritiri. Māori mythology considers the island to be a float of an ancestral fishing net. History Human use The first people to settle on the island were Māori of the Kawerau iwi. Later, members of the Ngāti Pāoa moved to the island, like the Kawerau partly for shark fishing until about 1700, when the Kawerau regained control and remained until forced to retr ...

Waipoua Forest
Waipoua Forest is a forest, on the west coast of the Northland Region of New Zealand's North Island. It preserves some of the best examples of kauri forest remaining in New Zealand. It is notable for having two of the largest living kauri trees, '' Tāne Mahuta'' and '' Te Matua Ngahere''. The forest was declared a sanctuary in 1952. A community-based volunteer organisation, the Waipoua Forest Trust, helps maintain the forest. The sanctuary is bordered to the south by the Professor W.R McGregor Reserve, named after W. R. McGregor (1894–1977). In the 1940s, McGregor successfully campaigned to end logging of the forest and to have it declared a sanctuary, a status it achieved in 1952. Today, the forest is a significant drawcard for visitors to Northland, with approximately 200,000 people visiting Tāne Mahuta every year. This has led to concerns about the health of the forest and the spread of kauri dieback disease. There are also easy walking tracks to Te Matua Ngahere ...

Cape Egmont
Cape Egmont, splitting Northern and Southern Taranaki Bights, is the westernmost point of Taranaki, on the west coast of New Zealand's North Island. It is located close to the volcanic cone of Mount Taranaki or Mount Egmont. It was named ''Kaap Pieter Boreel'' by Dutch explorer Abel Tasman in 1642, but renamed ''Cape Egmont'' by British explorer James Cook in 1769. (Note: Tasman did not sight Mount Taranaki, due to bad visibility, but Cook did, and after naming the mountain Mount Egmont, bestowed the same name on the promontory, which became the enduring name). Ironically, the cape retained a Dutch name, as Cook named the mountain and cape after the Earl of Egmont, who claimed descent of the Dutch House of Egmond. In July 1862, Kapoaiaia near Cape Egmont was the site of a hui between 600 members of Taranaki, Ngāti Ruanui, Ngā Rauru and Whanganui Māori iwi, discussing the First Taranaki War (1860–1861). There, it was agreed that the lands East and West of New Plymout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Māhia Peninsula
Māhia Peninsula (Maori: or ) is located on the east coast of New Zealand's North Island, in the Hawke's Bay region, between the towns of Wairoa and Gisborne. Rocket Lab has set up its Launch Complex 1 close to Ahuriri Point at the southern tip of the peninsula to launch its Electron rocket. Currently, it is being used as a commercial launcher of small satellites in the range of 135–235 kg, and miniature satellites called CubeSats. New Zealand's first orbital space launch took place from Launch Complex 1 on 21 January 2018. Geography The peninsula is long and wide. Its highest point is Rahuimokairoa, above sea level. The peninsula was once an island, but now a tombolo joins it to the North Island. Demographics The statistical area of Mahia, which at 472 square kilometres is larger than the peninsula and includes Nūhaka, had a population of 1,119 at the 2018 New Zealand census. This was a decrease of 153 people (−12.0%) since the 2006 census. There were 4 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autogamy
Autogamy, or self-fertilization, refers to the fusion of two gametes that come from one individual. Autogamy is predominantly observed in the form of self-pollination, a reproductive mechanism employed by many flowering plants. However, species of protists have also been observed using autogamy as a means of reproduction. Flowering plants engage in autogamy regularly, while the protists that engage in autogamy only do so in stressful environments. Occurrence Protists ''Paramecium aurelia'' '' Paramecium aurelia'' is the most commonly studied protozoan for autogamy. Similar to other unicellular organisms, ''Paramecium aurelia'' typically reproduce asexually via binary fission or sexually via cross-fertilization. However, studies have shown that when put under nutritional stress, ''Paramecium aurelia'' will undergo meiosis and subsequent fusion of gametic-like nuclei. This process, defined as hemixis, a chromosomal rearrangement process, takes place in a number of steps. First, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fruit Anatomy
Fruit anatomy is the plant anatomy of the internal structure of fruit. Fruits are the mature ovary or ovaries of one or more flowers. They are found in three main anatomical categories: aggregate fruits, multiple fruits, and simple fruits. Aggregate fruits are formed from a single compound flower and contain many ovaries or fruitlets. Examples include raspberries and blackberries. Multiple fruits are formed from the fused ovaries of multiple flowers or inflorescence. Examples include fig, mulberry, and pineapple. Simple fruits are formed from a single ovary and may contain one or many seeds. They can be either fleshy or dry. In fleshy fruit, during development, the pericarp (ovary wall) and other accessory structures become the fleshy portion of the fruit. The types of fleshy fruits are berries, pomes, and drupes. In some fruits, the edible portion is not derived from the ovary, but rather from the aril, such as the mangosteen or pomegranate, and the pineapple from which ti ...
