Philip Ashmole
Nelson Philip Ashmole (born 11 January 1934 in Amersham, BuckinghamshireMen of Achievement, p. 33, 15th Edition 93–94, Taylor & Francis, 1993. .), commonly known as Philip Ashmole, is an English zoologist and conservationist. His main research field focused on the avifauna of islands, including Saint Helena, Ascension Island, Tenerife, the Azores, and Kiritimati. Other interests include insects and spiders, of which Ashmole discovered and described some new taxa. Career In 1957, Ashmole graduated to Bachelor of Arts in Zoology at Brasenose College in Oxford. In the same year he became a research student at the Edward Grey Institute of Field Ornithology (EGI) and accompanied the scientists' couple Bernard and Sally Stonehouse and the ornithologist Doug Dorward on a two-year expedition of the British Ornithologists' Union to Ascension Island in the South Atlantic. Ashmole studied here the breeding and moult cycles of terns, which he wrote about in his Oxford doctoral thesis, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amersham
Amersham ( ) is a market town and civil parish within the unitary authority of Buckinghamshire, England, in the Chiltern Hills, northwest of central London, from Aylesbury and from High Wycombe. Amersham is part of the London commuter belt. There are two distinct areas: * Old Amersham, set in the valley of the River Misbourne, containing the 13th-century parish church of St Mary's Church, Old Amersham, St. Mary's and several old pubs and coaching inns * Amersham-on-the-Hill, which grew in the early 20th century around , which was served by the Metropolitan Railway, now the Metropolitan line, and the Great Central Railway. Geography Old Amersham occupies the valley floor of the River Misbourne. This is a chalk stream which dries up periodically. The river occupies a valley much larger than it is possible for a river the size of the present River Misbourne to cut, which makes it a misfit stream. The valley floor is at around Ordnance Datum, OD, and the valley top is at aro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David Lack
David Lambert Lack FRS (16 July 1910 – 12 March 1973) was a British evolutionary biologist who made contributions to ornithology, ecology, and ethology. His 1947 book, ''Darwin's Finches'', on the finches of the Galapagos Islands was a landmark work as were his other popular science books on ''Life of the Robin'' and ''Swifts in a Tower''. He developed what is now known as Lack's Principle which explained the evolution of avian clutch sizes in terms of individual selection as opposed to the competing contemporary idea that they had evolved for the benefit of species (also known as group selection). His pioneering life-history studies of the living bird helped in changing the nature of ornithology from what was then a collection-oriented field. He was a longtime director of the Edward Grey Institute of Field Ornithology at the University of Oxford. Education and early life Lack was born in London, the oldest of four children of Harry Lambert Lack MD FRCS, who later became Pre ...

Conservation (ethic)
Nature conservation is the moral philosophy and conservation movement focused on protecting species from extinction, maintaining and restoring habitats, enhancing ecosystem services, and protecting biological diversity. A range of values underlie conservation, which can be guided by biocentrism, anthropocentrism, ecocentrism, and sentientism, environmental ideologies that inform ecocultural practices and identities. There has recently been a movement towards evidence-based conservation which calls for greater use of scientific evidence to improve the effectiveness of conservation efforts. As of 2018 15% of land and 7.3% of the oceans were protected. Many environmentalists set a target of protecting 30% of land and marine territory by 2030. In 2021, 16.64% of land and 7.9% of the oceans were protected. The 2022 IPCC report on climate impacts and adaptation, underlines the need to conserve 30% to 50% of the Earth's land, freshwater and ocean areas – echoing the 30% goal of t ...

Saint Helena Earwig
The Saint Helena earwig or Saint Helena giant earwig (''Labidura herculeana'') is an extinct species of very large earwig endemism, endemic to the oceanic island of Saint Helena in the south Atlantic Ocean. Description Growing as large as long (including forceps), the Saint Helena earwig was the world's largest earwig. It was shiny black with reddish legs, short elytron, elytra and no hind wings. Distribution and ecology The earwig was endemic to Saint Helena, being found on the Horse Point Plain, Prosperous Bay Plain, and the Eastern Arid Area of the island. It was known to have lived in plain areas, Commidendrum, gumwood forests and seabird colony, seabird colonies in rocky places. The earwig inhabited deep burrows, coming out only at night following rain. Dave Clark of the London Zoo said that "the females make extremely good mothers". Known from subfossils remains, Saint Helena hoopoe, Saint Helena giant hoopoe could have been a predator of this earwig. History The Saint ...

Pincer (biology)
A pincer is the part of an arthropod that enables it to carry loads, to defend against other creatures, or to attack prey. In insects, the pincers are usually part of the creature's mandible, and often venom or acid can be injected through the pincer into an enemy during a pincer strike. Some arthropods such as crabs, lobsters, and scorpions possess pincers in the form of chelae at the ends of their front limbs (pedipalps), to assist in feeding, defence or even courtship. See also * Chela (organ) * Krukenberg procedure * Pedipalp * Pincer (tool) Pincers are a hand tool used in many situations where a mechanical advantage is required to pinch, cut or pull an object. Pincers are first-class levers, but differ from pliers in that the concentration of force is either to a point, or to an ... References {{reflist Arthropod anatomy ...

Forceps
Forceps (plural forceps or considered a plural noun without a singular, often a pair of forceps; the Latin plural ''forcipes'' is no longer recorded in most dictionaries) are a handheld, hinged instrument used for grasping and holding objects. Forceps are used when fingers are too large to grasp small objects or when many objects needed to be held at one time while the hands are used to perform a task. The term "forceps" is used almost exclusively in the fields of biology and medicine. Outside biology and medicine, people usually refer to forceps as tweezers, tongs, pliers, clips or clamps. Mechanically, forceps employ the principle of the lever to grasp and apply pressure. Depending on their function, basic surgical forceps can be categorized into the following groups: # Non-disposable forceps. They should withstand various kinds of physical and chemical effects of body fluids, secretions, cleaning agents, and sterilization methods. # Disposable forceps. They are usually made o ...

Ascension Crake
The Ascension crake (''Mundia elpenor'') is an extinct flightless bird that previously lived on Ascension Island in the South Atlantic Ocean. Like many other flightless birds on isolated islands, it was a rail. It was declared extinct by Groombridge in 1994; BirdLife International confirmed this in 2000 and 2004. The bird was endemic to Ascension Island. Numerous subfossil bones of the bird have been found in deposits at the base of vertical fumaroles. Peter Mundy, a 17th-century merchant and traveler gave an account of the bird and made a sketch of it when he visited Ascension Island in June 1656. It was described by Mundy as: It most likely lived in the near-desert areas of the island and primarily ate sooty tern (''Sterna fuscata'') eggs. It is probable that it became extinct after rats were introduced to the island in the 18th century, but it may have survived until the introduction of feral cats in 1815. The bird was regarded by Storrs Olson as a relative of '' Atlan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ascension Night Heron
The Ascension night heron (''Nycticorax olsoni'') is an extinct night heron species from the genus ''Nycticorax'' endemic to the South Atlantic island of Ascension Island, Ascension. It is predominantly known from the bone fragments of six specimens found in guano deposits and caves on Ascension Island and described by Philip Ashmole, Kenneth Edwin Laurence Ryder Simmons, and William Richmond Postle Bourne in 2003. The Ascension night heron disappeared in the 16th century. Its scientific name commemorates Storrs L. Olson. A possible report on the Ascension night heron is found in the chapter "''D'une isle nommte I'Ascention''" in the travel report ' by André Thévet. Given that Thévet alludes to a flightless bird named ''Aponar'' in 1555, it could be quite possible that he was referring to the Ascension night heron. The English translation of Thévet's notice about the ''Aponar'' (sometimes also written ''Aponat'' or ''Aponard'') is stated as:Jeremy Gaskell: Who killed the Grea ...

Saint Helena Hoopoe
The Saint Helena hoopoe (''Upupa antaios''), also known as the Saint Helena giant hoopoe or giant hoopoe, is an extinct species of the hoopoe (family Upupidae), known exclusively from an incomplete subfossil skeleton. It was last seen around 1550. Description It was endemic to the island of Saint Helena in the South Atlantic. ''Upupa antaios'' was a large bird, having bigger and more robust skull and wing elements than those of the common hoopoe (''Upupa epops''). Its beak is also more massive and decurved in comparison with common hoopoe, which could be the ancestor of ''U. antaios''. It was most likely flightless.Storrs L. Olson.

Nuclear Weapons Testing
Nuclear weapons tests are experiments carried out to determine nuclear weapons' effectiveness, Nuclear weapon yield, yield, and explosive capability. Testing nuclear weapons offers practical information about how the weapons function, how detonations are affected by different conditions, and how personnel, structures, and equipment are affected when subjected to Nuclear explosion, nuclear explosions. However, nuclear testing has often been used as an indicator of scientific and military strength. Many tests have been overtly political in their intention; most List of countries with nuclear weapons, nuclear weapons states publicly declared their nuclear status through a nuclear test. The first nuclear device was detonated as a test by the United States at the Trinity site in New Mexico on July 16, 1945, with a yield approximately TNT equivalent, equivalent to 20 kilotons of TNT. The first thermonuclear weapon technology test of an engineered device, codenamed "Ivy Mike", was teste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
