Greenland Wolf
The Greenland wolf ( taxonomic Latin: ''Canis lupus orion'', Danish: ''grønlandsulv'') is a subspecies of gray wolf that is native to Greenland. Historically, it was heavily persecuted, but today it is fully protected and about 90% of the wolf's range falls within the boundaries of the Northeast Greenland National Park. A recent genomic study has shown that wolves of Ellesmere Island, Canada, likely should be included in the same subspecies, a view also supported by earlier morphological reviews. The entire population is very small, probably about 200 individuals but with significant uncertainty due to its very remote range. Taxonomy and evolution In 1935, the British zoologist Reginald Pocock attributed the subspecies name ''Canis lupus orion'' to a specimen from Cape York, northwest Greenland. He also attributed the name ''Canis lupus arctos'' (Arctic wolf) to a specimen from Melville Island in the nearby Queen Elizabeth Islands, Canada. Both wolves are recognized as separ ...

Peary Land
Peary Land is a peninsula in northern Greenland, extending into the Arctic Ocean. It reaches from Victoria Fjord in the west to Independence Fjord in the south and southeast, and to the Arctic Ocean in the north, with Cape Morris Jesup, the northernmost point of Greenland's mainland, and Cape Bridgman in the northeast. History Ancient settlements Peary Land was historically inhabited by three separate cultures, during which times the climate was milder than presently: *Independence I culture, Paleo-Eskimo (around 2000 BC, oldest remains dating from 2400 BC) *Independence II culture, Paleo-Eskimo (800 BC to 200 BC) * Thule culture (ancestral to the modern Inuit, around AD 1300) Peary's explorations The area is named after Robert E. Peary, who first explored it during his expedition of 1891 to 1892. Originally, Peary Land was believed to be an island, separated from the main island by the so-called Peary Channel, an assumed connection between Nordenskiöld Fjord and ...

Sirius Dog Sled Patrol
The Sirius Dog Sled Patrol ( da, Slædepatruljen Sirius), known informally as ''Siriuspatruljen'' (the Sirius Patrol) and formerly known as ''North-East Greenland Sledge Patrol'' and ''Resolute Dog Sled Patrol'', is an elite Danish naval unit. It conducts long-range reconnaissance patrolling, and enforces Danish sovereignty in the Arctic wilderness of northern and eastern Greenland, an area that includes the Northeast Greenland National Park, which is the largest national park in the world. Patrolling is usually done in pairs and using dog sleds with about a dozen dogs, sometimes for four months and often without additional human contact. The Sirius Dog Sled Patrol has the ability to engage militarily, and has done so historically. Its purpose is to maintain Danish sovereignty and police its area of responsibility.Formål ...

Arctic Fox
The Arctic fox (''Vulpes lagopus''), also known as the white fox, polar fox, or snow fox, is a small fox native to the Arctic regions of the Northern Hemisphere and common throughout the Arctic tundra biome. It is well adapted to living in cold environments, and is best known for its thick, warm fur that is also used as camouflage. It has a large and very fluffy tail. In the wild, most individuals do not live past their first year but some exceptional ones survive up to 11 years. Its body length ranges from , with a generally rounded body shape to minimize the escape of body heat. The Arctic fox preys on many small creatures such as lemmings, voles, ringed seal pups, fish, waterfowl, and seabirds. It also eats carrion, berries, seaweed, and insects and other small invertebrates. Arctic foxes form monogamous pairs during the breeding season and they stay together to raise their young in complex underground dens. Occasionally, other family members may assist in raising the ...

Inbred
Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically. By analogy, the term is used in human reproduction Human reproduction is sexual reproduction that results in human fertilization to produce a human offspring. It typically involves sexual intercourse between a sexually mature human male and female. During sexual intercourse, the interaction b ..., but more commonly refers to the genetic disorders and other consequences that may arise from expression of wikt:deleterious, deleterious or dominance (genetics), recessive traits resulting from incestuous sexual relationships and consanguinity. Animals avoid incest only rarely. Inbreeding results in homozygous, homozygosity, which can increase the chances of offspring being affected by recessive phenotypic trait, traits. In extreme cases, this usually leads to at least temporarily decreased Fitness (biology), biological fitness of a population ...

Arctic Hare
The Arctic hare (''Lepus arcticus'') is a species of hare highly adapted to living in the Arctic tundra and other icy biomes. The Arctic hare survives with shortened ears and limbs, a small nose, fat that makes up close to 20% of its body, and a thick coat of fur. It usually digs holes in the ground or under the snow to keep warm and to sleep. Arctic hares look like rabbits but have shorter ears, are taller when standing, and, unlike rabbits, can thrive in extreme cold. They can travel together with many other hares, sometimes huddling with dozens or more, but are usually found alone, sometimes taking more than one partner. The Arctic hare can run up to . Taxonomy Arctic explorer John Ross described the Arctic hare in 1819. Description The Arctic hare is one of the largest living lagomorphs. Typically, this species measures from long, not counting a tail length of . The body mass of this species is typically between , though large individuals can weigh up to .Burnie D and W ...

Muskox
The muskox (''Ovibos moschatus'', in Latin "musky sheep-ox"), also spelled musk ox and musk-ox, plural muskoxen or musk oxen (in iu, ᐅᒥᖕᒪᒃ, umingmak; in Woods Cree: ), is a hoofed mammal of the family Bovidae. Native to the Arctic, it is noted for its thick coat and for the strong odor emitted by males during the seasonal rut, from which its name derives. This musky odor has the effect of attracting females during mating season. Its Inuktitut name "umingmak" translates to "the bearded one". Its Woods Cree names "mâthi-môs" and "mâthi-mostos" translate to "ugly moose" and "ugly bison", respectively. Muskoxen primarily live in Greenland and the Canadian Arctic of the Northwest Territories and Nunavut, with reintroduced populations in the American state of Alaska, the Canadian territory of Yukon, and Siberia, and an introduced population in Norway, part of which emigrated to Sweden, where a small population now lives.

Genome
In the fields of molecular biology and genetics, a genome is all the genetic information of an organism. It consists of nucleotide sequences of DNA (or RNA in RNA viruses). The nuclear genome includes protein-coding genes and non-coding genes, other functional regions of the genome such as regulatory sequences (see non-coding DNA), and often a substantial fraction of 'junk' DNA with no evident function. Almost all eukaryotes have mitochondria and a small mitochondrial genome. Algae and plants also contain chloroplasts with a chloroplast genome. The study of the genome is called genomics. The genomes of many organisms have been sequenced and various regions have been annotated. The International Human Genome Project reported the sequence of the genome for ''Homo sapiens'' in 200The Human Genome Project although the initial "finished" sequence was missing 8% of the genome consisting mostly of repetitive sequences. With advancements in technology that could handle seq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 co ...
