Newfoundland Wolf
The Newfoundland wolf (''Canis lupus beothucus'') was a subspecies of grey wolf that was native to Newfoundland. As a food source, the species would prey and rely on the Newfoundland caribou. During the autumn and early winter, some wolves would turn white while others remained dark enough to look black. Description It was described as being a medium-sized, slender-skulled wolf with a white pelt, though melanists also occurred. In comparison to its mainland relatives it bears a striking difference in its internal accessory cusp angles allowing for distinction between subspecies. The last specimen was reportedly killed in 1911. Taxonomy This wolf is recognized as a subspecies of ''Canis lupus'' in the taxonomic authority ''Mammal Species of the World (2005)''. In 1912, Gerrit S. Miller Jr have concluded that in North America, specifically west of the Mississippi River and Hudson Bay, and north of the Platte and Columbia rivers, there are three types of wolves: timber-wolf, pla ...

Glover Morrill Allen
Glover Morrill Allen (February 8, 1879 – February 14, 1942) was an American zoologist. Born in Walpole, New Hampshire, the son of Reverend Nathaniel Glover Allen and Harriet Ann (Schouler) Allen, he studied at Harvard University. While still a student, Allen published ''The Birds of Massachusetts'' and ''A List of the Birds of New Hampshire''. After graduating in 1901, he was appointed librarian to the Boston Society of Natural History, and in 1904, obtained a Ph.D. from Harvard. From 1924, he lectured in zoology at Harvard and held the position of Curator of Mammals in the Museum of Comparative Zoology. He traveled widely, to Central and South America, to East and West Africa, the Nile, the Belgian Congo as a member of the eight-man Harvard Medical African Expedition (1926–1927), and Australia as a member of the six-man Harvard Australian Expedition (1931–1932) along with his student, Ralph Nicholson Ellis.

Thomas Barbour
Thomas Barbour (August 19, 1884 – January 8, 1946) was an American herpetologist. He was the first president of the Dexter School in 1926. From 1927 until 1946, he was director of the Harvard Museum of Comparative Zoology (MCZ) founded in 1859 by Louis Agassiz at Harvard University in Cambridge, Massachusetts. Life and career Barbour, the eldest of four brothers, was born in 1884 to Colonel William Barbour, and his wife, Julia Adelaide Sprague. Colonel Barbour was founder and president of The Linen Thread Company, Inc., a successful thread manufacturing enterprise having much business in the United States, Ireland, and Scotland. Although born on Martha's Vineyard, Massachusetts, where the family was spending the summer, Barbour grew up in Monmouth, New Jersey, where one of his younger brothers, William Warren Barbour, entered the political arena, eventually serving as U.S. Senator from New Jersey from 1931 to 1937 and again from 1938 to 1943. At age fifteen, Thomas Barbo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies Of Canis Lupus
There are 38 subspecies of ''Canis lupus'' listed in the taxonomic authority '' Mammal Species of the World'' (2005, 3rd edition). These subspecies were named over the past 250 years, and since their naming, a number of them have gone extinct. The nominate subspecies is the Eurasian wolf (''Canis lupus lupus''). Taxonomy In 1758, the Swedish botanist and zoologist Carl Linnaeus published in his ''Systema Naturae'' the binomial nomenclature – or the two-word naming – of species. '' Canis'' is the Latin word meaning "dog", and under this genus he listed the dog-like carnivores including domestic dogs, wolves, and jackals. He classified the domestic dog as ''Canis familiaris'', and on the next page he classified the wolf as ''Canis lupus''. Linnaeus considered the dog to be a separate species from the wolf because of its head, body, and ''cauda recurvata'' – its upturning tail – which is not found in any other canid. In 1999, a study of mitochondrial DNA indicated that t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Newfoundland (island)
Newfoundland ( , ; , ) is a large island within the Canadian province of Newfoundland and Labrador. It is situated off the eastern coast of the Northern America, North American mainland and the geographical region of Labrador. The island contains 29 percent of the province's land area, but is home to over 90% of the province's population, with about 60% of the province's population located on the small southeastern Avalon peninsula. The island is separated from the Labrador Peninsula by the Strait of Belle Isle and from Cape Breton Island by the Cabot Strait. It blocks the mouth of the Saint Lawrence River, creating the Gulf of Saint Lawrence, the world's largest estuary. Newfoundland's nearest neighbour is the French overseas collectivity of Saint Pierre and Miquelon. With an area of , Newfoundland is the List of islands by area, world's 16th-largest island, List of Canadian islands by area, Canada's fourth-largest island, and the largest Canadian island outside Northern Can ...

Reindeer
The reindeer or caribou (''Rangifer tarandus'') is a species of deer with circumpolar distribution, native to Arctic, subarctic, tundra, taiga, boreal, and mountainous regions of Northern Europe, Siberia, and North America. It is the only representative of the genus ''Rangifer''. More recent studies suggest the splitting of reindeer and caribou into six distinct species over their range. Reindeer occur in both Animal migration, migratory and wiktionary:sedentary#Adjective, sedentary populations, and their herd sizes vary greatly in different regions. The tundra subspecies are adapted for extreme cold, and some are adapted for long-distance migration. Reindeer vary greatly in size and color from the smallest, the Svalbard reindeer (''R.'' (''t.'') ''platyrhynchus''), to the largest, Osborn's caribou (''R. t. osborni''). Although reindeer are quite numerous, some species and subspecies are in decline and considered Vulnerable species, vulnerable. They are unique among deer (Ce ...

Melanism
Melanism is the congenital excess of melanin in an organism resulting in dark pigment. Pseudomelanism, also called abundism, is another variant of pigmentation, identifiable by dark spots or enlarged stripes, which cover a large part of the body of the animal, making it appear melanistic. The morbid deposition of black matter, often of a malignant character causing pigmented tumors, is called melanosis. Adaptation Melanism related to the process of adaptation is called adaptive. Most commonly, dark individuals become fitter to survive and reproduce in their environment as they are better camouflaged. This makes some species less conspicuous to predators, while others, such as leopards, use it as a foraging advantage during night hunting. Typically, adaptive melanism is heritable: A dominant allele, which is entirely or nearly entirely expressed in the phenotype, is responsible for the excessive amount of melanin. By contrast, adaptive melanism associated with Batesian mimi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Wolves Of North America (1944) C
''The'' is a grammatical article in English, denoting nouns that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pronoun ''thee' ...

Labrador Wolf
The Labrador wolf (''Canis lupus labradorius'') is a subspecies of gray wolf native to Labrador, Newfoundland, and northern Quebec. It has been described as ranging in color from dark grizzly-gray to almost white,Glover, A. (1942)''Extinct and vanishing mammals of the western hemisphere, with the marine species of all the oceans'' American Committee for International Wild Life Protection, p. 209. and of being closely related to the Newfoundland wolf (''C. l. beothucus''). This wolf is recognized as a subspecies of ''Canis lupus'' in the taxonomic authority ''Mammal Species of the World (2005)''. History Due to over-hunting in the early 1900s, Labrador wolf sightings were infrequent through the 1950s. Around that time period, the caribou population began to increase at a steady rate, which then correlated with an increase in the wolf population. However, the increase in number of the Labrador wolf was not enough to offset the continuing rise in caribou in the region, causing a r ...

Labrador
Labrador () is a geographic and cultural region within the Canadian province of Newfoundland and Labrador. It is the primarily continental portion of the province and constitutes 71% of the province's area but is home to only 6% of its population. It is separated from the island of Newfoundland by the Strait of Belle Isle. It is the largest and northernmost geographical region in the four Atlantic provinces. Labrador occupies most of the eastern part of the Labrador Peninsula. It is bordered to the west and south by the province of Quebec. Labrador also shares a small land border with the territory of Nunavut on Killiniq Island. The indigenous peoples of Labrador include the Northern Inuit of Nunatsiavut, the Southern Métis of NunatuKavut, and the Innu of Nitassinan. Etymology Labrador is named after João Fernandes Lavrador, a Portuguese explorer who sailed along the coasts of the Labrador Peninsula in 1498–99.

Extinct Subspecies Of Canis Lupus
Extinction is the termination of an organism by the death of its last member. A taxon may become functionally extinct before the death of its last member if it loses the capacity to reproduce and recover. As a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, and mammoths. Through evolution, species arise through the process of speciation. Species become extinct when they are no longer able to survive in changing conditions or against superior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Newfoundland (island)
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becoming ...
