Libythea Collenettei
''Libythea collenettei'', the Marquesan snout butterfly, is a species of Nymphalid butterfly in the subfamily Libytheinae. The species was first described by Edward Bagnall Poulton and Norman Denbigh Riley in 1923. The specific name honours its original collector, Cyril Leslie Collenette, a member of the 1925 St George Expedition to French Polynesia. It is endemic to French Polynesia, ''L. collenettei'' is the only species of butterfly endemic to the Marquesas Islands. Its conservation status has not been evaluated by the IUCN. However, a survey by Akito Y. Kawahara and Emmanuel Toussaint in 2018 designates it as endangered using the IUCN 3.1 criterion, but with an overall lack of sightings it is possibly extinct. It was previously listed as extinct, but was rediscovered in 2001 by Kawahara. It is threatened by deforestation because encroaching Caribbean pine tree farms incentivize clearing the host plant ''Celtis pacifica'' from the Toovii Plateau of Nuku Hiva. It is morp ...

Edward Bagnall Poulton
Sir Edward Bagnall Poulton, FRS HFRSE FLS (27 January 1856 – 20 November 1943) was a British evolutionary biologist, a lifelong advocate of natural selection through a period in which many scientists such as Reginald Punnett doubted its importance. He invented the term sympatric for evolution of species in the same place, and in his book '' The Colours of Animals'' (1890) was the first to recognise frequency-dependent selection. Poulton is also remembered for his pioneering work on animal coloration. He is credited with inventing the term aposematism for warning coloration, as well as for his experiments on 'protective coloration' (camouflage). Poulton became Hope Professor of Zoology at the University of Oxford in 1893. Life Edward Poulton was born in Reading, Berkshire on 27 January 1856 the son of the architect William Ford Poulton and his wife, Georgina Sabrina Bagnall. He was educated at Oakley House School in Reading. Between 1873 and 1876, Poulton studied at Jes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voltinism
Voltinism is a term used in biology to indicate the number of broods or generations of an organism in a year. The term is most often applied to insects, and is particularly in use in sericulture, where silkworm varieties vary in their voltinism. * Univoltine (monovoltine) – (adjective) referring to organisms having one brood or generation per year * Bivoltine (divoltine) – (adjective) referring to organisms having two broods or generations per year *Trivoltine – (adjective) referring to organisms having three broods or generations per year * Multivoltine (polyvoltine) – (adjective) referring to organisms having more than two broods or generations per year * Semivoltine – There are two meanings: :* (''biology'') Less than univoltine; having a brood or generation less often than once per year :* or (adjective) referring to organisms whose generation time is more than one year. Examples The speckled wood butterfly is univoltine in the northern part of its range, e.g. nort ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mohotani
Mohotani (sometimes spelt ''Moho Tani''; also called ''Molopu'' or ''Motane'') is an uninhabited island southeast of Hiva Oa and east of Tahuata in the southern Marquesas Islands. It has an area of 15 km2. Much of the island's sparse vegetation has been destroyed by feral goats and sheep, to the extent that following its rare rains, the sea around it is stained red from runoff. Early reports describes the island as fertile, with forest and fields. When Thor Heyerdahl visited the island in 1938, there were only a few goats and remains of deserted huts and villages. Mohotani is administratively part of the commune (municipality) of Hiva-Oa, itself in the administrative subdivision of the Marquesas Islands. It is reported that at one time the island was inhabited by a clan called the “Moi a Tiu”, but that population has long since been wiped out by disease and war, the few survivors having departed for Hiva ʻOa. In pre-European times, the island was considered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ua Huka
Ua Huka is one of the Marquesas Islands, in French Polynesia, an overseas territory of France in the Pacific Ocean. It is situated in the northern group of the archipelago, approximately to the east of Nuku Hiva, at . Name Ua Huka is sometimes also found spelled ''Roohka'' or ''Ua Huna''. The first Western navigator to sight the island was U.S. Navy Captain Joseph Ingraham in 1791. He named the island "Washington Island" in honor of U.S. President George Washington, a name which was eventually extended to include all of the northern group of the Marquesas Islands. Other names for the island include ''Riou'' and ''Solide''. ''See also Names of the Marquesas Islands''. The spider genus '' Uahuka'' is named after this island. History Although Ua Huka is located in the northern Marquesas, historically, culturally and linguistically the island's tribes were far more closely aligned with the southern Marquesas Islands, especially with the tribes from Pepane, in the eastern h ...

Tahuata
Tahuata is the smallest of the inhabited Marquesas Islands, in French Polynesia, an overseas territory of France in the Pacific Ocean. It is located 4 km (2.5 mi.) to the south of the western end of Hiva Oa, across the Canal du Bordelais, called Ha‘ava in Marquesan. History Archæological evidence indicates that Tahuata was inhabited by Polynesians as early as AD 200. In later pre-European times, the tribes of Tahuata were allied with the tribes from the Nuku province of Hiva Oa, and the island was considered a dependency of that province. The first recorded sighting by Europeans was by the Spanish expedition of Álvaro de Mandaña on 22 July 1595. They charted the island as ''Santa Cristina''. They landed at Vaitahu that they named ''Madre de Dios'' (God's Mother in Spanish). According to the Spanish accounts Tahuata had fowls, fish, sugar cane, plantains, nuts and fruits. The existent town was built on two sides of a rectangular space, the houses being of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hiva Oa
With its , Hiva Oa is the second largest island in the Marquesas Islands, in French Polynesia, an overseas territory of France in the Pacific Ocean. Located at 9 45' south latitude and 139 W longitude, it is the largest island of the southern Marquesas group. Around 2,200 people reside on the island. A volcano, Temetiu, is Hiva Oa's highest point with . History Colonial period The first recorded sighting of Hiva Oa by the Europeans was by the Spanish expedition of Álvaro de Mendaña on 21 July 1595. They charted it as ''Dominica''. Overview Administratively, Hiva Oa is part of the commune (municipality) of Hiva-Oa, itself in the administrative subdivision of the Marquesas Islands.

Ua Pou
Ua Pou (french: Ua Pou, North Marquesan: ''’uapou'') is the third largest of the Marquesas Islands, in French Polynesia, an overseas territory of France in the Pacific Ocean. History Pre-European history Ua Pou is the only major island that was unified under a single monarch prior to the arrival of European explorers. Prior to the island's unification, reportedly about 1585, there is evidence that the tribes of Ua Pou were sometimes united in war with the tribes of Te I'i on Nuku Hiva against those of Tai Pi Vai. Despite the fact that tribes from both the eastern and western halves of Ua Pou were often united in war against each other, however, it appears that such differences among them were not considered when members of tribes from either side of the island sought refuge among the tribes of Te I'i on Nuku Hiva. The early Polynesian settlers of Ua Pou lived under rock overhangs, as excavations from 1982 onwards at the Anapua rock shelter, not far from the village of Ha ...

Fatu Hiva
Fatu-Hiva (the "H" is not pronounced, see name section below) is the southernmost island of the Marquesas Islands in French Polynesia, an overseas territory of France in the Pacific Ocean. With Motu Nao as its closest neighbor, it is also the most isolated of the inhabited islands. ''Fatu Hiva'' is also the title of a book by explorer and archaeologist Thor Heyerdahl, in which he describes his stay on the island in the 1930s. Name The name of the island in Marquesan is Fatu Iva (without "h": ). However, the name was recorded by Europeans as ''Fatu-Hiva,'' perhaps under the influence of other Marquesan islands containing the element ''Hiva'' (Nuku-Hiva and Hiva-Oa) and also because in French the letter "h" is silent. The spelling ''Fatu-Hiva'' has now become official. The island was named ''Isla Magdalena'' ("Magdalene Island") by Spanish explorers in the 16th century, a name rarely used. Hatauheva is another name form that appears in 1817, by Camille de Roquefeuil during his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic
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] |
