Gynaephora Groenlandica
''Gynaephora groenlandica'', the Arctic woolly bear moth, is an erebid moth native to the High Arctic in the Canadian archipelago, Greenland and Wrangel Island in Russia. It is known for its slow rate of development, as its full caterpillar life cycle may extend up to 7 years, with moulting occurring each spring. This species remains in a larval state for the vast majority of its life. Rare among Lepidoptera, it undergoes an annual period of diapause that lasts for much of the calendar year, as ''G. groenlandica'' is subject to some of the longest, most extreme winters on Earth.Bennett VA, Lee RE Jr, Nauman JS, Kukal O. Selection of overwintering microhabitats used by the arctic woollybear caterpillar, ''Gynaephora groenlandica''. Cryo Letters. 2003 May-Jun;24(3):191-200. In this dormant state, it can withstand temperatures as low as −70 °C. The Arctic woolly bear moth also exhibits basking behavior, which aids in temperature regulation and digestion and affects both met ...

Greenland
Greenland ( kl, Kalaallit Nunaat, ; da, Grønland, ) is an island country in North America that is part of the Kingdom of Denmark. It is located between the Arctic and Atlantic oceans, east of the Canadian Arctic Archipelago. Greenland is the world's largest island. It is one of three constituent countries that form the Kingdom of Denmark, along with Denmark and the Faroe Islands; the citizens of these countries are all citizens of Denmark and the European Union. Greenland's capital is Nuuk. Though a part of the continent of North America, Greenland has been politically and culturally associated with Europe (specifically Norway and Denmark, the colonial powers) for more than a millennium, beginning in 986.The Fate of Greenland's Vikings , by Dale Mackenzie Brown, ''Archaeological Institute of America'', ...

Gynaephora Rossii
''Gynaephora rossii'', in English known as Ross' tussock moth, is a species of tussock moth in the family Erebidae. It is widespread in the tundras and highlands of the Holarctic. It has large, furry caterpillars which seem to eat mostly saxifrages. Taxonomy This moth was first described in 1835 by John Curtis as ''Laria rossii'', who placed it in the genus ''Laria'' described by Franz von Paula Schrank in 1802; the genus ''Laria'', however, had already been used in 1763 for a genus of beetles by Scolipi (now ''Pria''), so the species required moving to another genus. Heinrich Benno Möschler first moved it to the genus '' Dasychira'' in his 1870 work on the moths of Labrador. Otto Staudinger also classified it in the genus ''Dasychira'' in 1901, but in 1927 William Schaus moved it to the genus ''Byrdia''. Also in 1927 Otto Bang-Haas described the subspecies ''Dasychira rossii relictus'' from the eastern Sayan Mountains. A year later, in 1928, Shōnen Matsumura described ''Konoka ...

Haplotype
A haplotype ( haploid genotype) is a group of alleles in an organism that are inherited together from a single parent. Many organisms contain genetic material ( DNA) which is inherited from two parents. Normally these organisms have their DNA organized in two sets of pairwise similar chromosomes. The offspring gets one chromosome in each pair from each parent. A set of pairs of chromosomes is called diploid and a set of only one half of each pair is called haploid. The haploid genotype (haplotype) is a genotype that considers the singular chromosomes rather than the pairs of chromosomes. It can be all the chromosomes from one of the parents or a minor part of a chromosome, for example a sequence of 9000 base pairs. However, there are other uses of this term. First, it is used to mean a collection of specific alleles (that is, specific DNA sequences) in a cluster of tightly linked genes on a chromosome that are likely to be inherited together—that is, they are likely to be con ...

Disjunct Distribution
In biology, a taxon with a disjunct distribution is one that has two or more groups that are related but considerably separated from each other geographically. The causes are varied and might demonstrate either the expansion or contraction of a species' range. Range fragmentation Also called range fragmentation, disjunct distributions may be caused by changes in the environment, such as mountain building and continental drift or rising sea levels; it may also be due to an organism expanding its range into new areas, by such means as rafting, or other animals transporting an organism to a new location (plant seeds consumed by birds and animals can be moved to new locations during bird or animal migrations, and those seeds can be deposited in new locations in fecal matter). Other conditions that can produce disjunct distributions include: flooding, or changes in wind, stream, and current flows, plus others such as anthropogenic introduction of alien introduced species either acciden ...

Yukon
Yukon (; ; formerly called Yukon Territory and also referred to as the Yukon) is the smallest and westernmost of Canada's three territories. It also is the second-least populated province or territory in Canada, with a population of 43,964 as of March 2022. Whitehorse, the territorial capital, is the largest settlement in any of the three territories. Yukon was split from the North-West Territories in 1898 as the Yukon Territory. The federal government's ''Yukon Act'', which received royal assent on March 27, 2002, established Yukon as the territory's official name, though ''Yukon Territory'' is also still popular in usage and Canada Post continues to use the territory's internationally approved postal abbreviation of ''YT''. In 2021, territorial government policy was changed so that “''The'' Yukon” would be recommended for use in official territorial government materials. Though officially bilingual (English and French), the Yukon government also recognizes First Natio ... [...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] |
Dicallomera Fascelina
''Dicallomera fascelina'', the dark tussock, is a moth in the family Erebidae. The species was first described by Carl Linnaeus in his 1758 10th edition of ''Systema Naturae''. It is found in most of Europe, through the Palearctic to Central Asia to Korea. Technical description and variation The wingspan is 35–45 mm. "Forewing ash-grey, lighter at the costal margin, with black and yellow irrorations, the median area bounded on the inner side by a regularly curved dark transverse line and on the outer side by a similar one twice or three times broken; both lines being most distinct at the costal margin. Hindwing grey or whitish. ab. ''proletaria'' Strand does not attain more than 29 mm. in the male; it is also distinguished by the ground colour of both wings being olive-grey, with the two transverse lines rather indistinct and not reaching the hindmargin, while the discocellular spot is more conspicuous than in true ''fascelina''. - ''medicagitlis'' Hbn. is darker i ...

Arctia
''Arctia'' is a genus of tiger moths in the family Erebidae. Therein, it belongs to the subtribe Arctiina in the tribe Arctiini in the subfamily Arctiinae. Species are well distributed throughout North America, Palearctic, India, and Sri Lanka. As a result of phylogenetic studies by Rönkä et al. in 2016, the following genera were determined to be synonyms with ''Arctia'', and their species were reclassified in this genus. :''Acerbia'' :''Ammobiota'' :''Atlantarctia'' :''Borearctia'' :''Callarctia'' :''Chionophila'' :''Eupsychoma'' :''Gonerda'' :''Nemeophila'' :''Oroncus'' :''Pararctia'' :''Platarctia'' :''Platyprepia'' :''Preparctia'' :''Sinoarctia'' Description Palpi porrect (extending forward), reaching beyond the frons where the first two joints are hairy. Antennae bipectinated in male, with short branches swollen at extremity, and with a terminal bristle, whereas female has serrate. Legs hairy with hind tibia bears two spur pairs. Forewings rather short and broad. Spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Koldewey
Carl Christian Koldewey (26 October 1837 – 17 May 1908) was a German Arctic explorer. He led both German North Polar Expeditions. Life and career Koldewey was the son of merchant Johann Christian Koldewey and his wife Wilhelmine Meyer. Koldewey enrolled as a sailor in 1853 immediately after Grammar school at Clausthal. At age 22, he attended the Naval school in Bremen, where he was among Arthur Breusing's best pupils. Later he went to sea again but returned to Naval school in 1861. After becoming a captain, Koldewey studied mathematics, physics, and astronomy at the universities of Hanover and Göttingen between 1866 and 1867. Expeditions Through his teacher Breusing and encouraged by August Petermann Koldewey was given the leadership of the first Arctic expedition as captain of ship ''Grönland''. He had the choice of either advancing northwards as far as possible along Greenland's east coast or to reach so-called Gillis-Land by travelling around Spitsbergen. But adverse con ...

German North Polar Expedition
The German North Polar Expeditions were a short series of mid-19th century German expeditions to the Arctic. The aim was to explore the North Pole region and to brand the newly united, Prussian-led German Empire as a great power. In 1866, German geographer August Petermann wrote a pamphlet strongly advocating German participation in the international quest for the North Pole, which stimulated a German expedition. First German North Polar Expedition The first expedition took place in the summer of 1868 and was led by Carl Koldewey on the vessel ''Grönland''. The expedition explored some hitherto unknown coastal tracts of northeastern Spitsbergen, but did otherwise not lead to any new scientific knowledge. However, it served as preparation for the second expedition. Second German North Polar Expedition The second expedition consisted of a two-vessel convoy: * – a schooner specifically constructed for the expedition, with a crew of 15 men commanded by Carl Koldewey * '' ...

Germania (ship, 1869)
The ''Germania'' was a German schooner built in Geestemünde, Bremerhaven, in 1869. Career Fitted with an auxiliary steam engine, it was especially built as the main research ship of the Second German North Polar Expedition of 1869–1870 that explored northeastern Greenland. The captain of the ship was Carl Koldewey, leader of the expedition. Emperor Wilhelm I was present at the ship launching ceremony on 16 April 1869. The smaller schooner, ''Hansa''—not fitted with an auxiliary engine—was the convoy and supply ship of the ''Germania'' during the expedition. During the wintering period, ''Hansa'' was crushed by pack ice and sank. However, ''Germania'' managed to force its way through the ice, returning to Bremerhaven on 11 September 1870. ''Germania'' took part in a further two Arctic expeditions, being refitted as a whaler A whaler or whaling ship is a specialized vessel, designed or adapted for whaling: the catching or processing of whales.

Gottlieb August Wilhelm Herrich-Schäffer
Gottlieb August Wilhelm Herrich-Schäffer (17 December 1799 – 14 April 1874) was a German entomologist and physician. He was born, and died, in Regensburg. Herrich-Schäffer studied and collected particularly butterflies and moths (Lepidoptera). He was chairman of the Regensburg Botanical Society () from 1861 to 1871, and was awarded an honorary citizenship of Regensburg in 1871. He wrote ''Systematische Bearbeitung der Schmetterlinge von Europa'' between 1843 and 1856, one of the most influential works on the higher classification of Lepidoptera of the 19th century. Many of the lepidopteran higher taxa recognized today were defined in this work for the first time. He based his classification mostly on wing venation. Parts of his collection went to Otto Staudinger at the Museum für Naturkunde in Berlin and M. J. Bastelberg at the Zoologische Staatssammlung München. Many Microlepidoptera in his collection were given to Ottmar Hofmann (1835–1900) at the Natural History Museum, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
