Jämthund
The Jämthund, also called the Swedish Elkhound, is a breed of dog of the Spitz type that is found in Northern Europe. The Jämthund is eponymous with Jämtland, a province in the middle of Sweden. History The Swedish Elkhound is one of a number of breeds of spitz-type hunting dogs that have been known throughout Scandinavia for centuries. Historically these dogs have been used to hunt a wide variety of game including bear, elk, wolf and lynx. The Swedish Elkhound received official recognition as a breed in 1946, due to intensive work by Aksel Lindström and others. Before that, both it and the Norwegian Elkhound were seen as the same breed. They are both used for hunting large game, such as moose and bear. Lineage The breed falls under the mitochondrial DNA sub-clade referred to as d1 that is only found in northern Scandinavia. It is the result of a male dog-female wolf hybridization that occurred post-domestication. Subclade d1 originated 480–3,000 years ago and it includes ...

Jämtland
Jämtland (; no, Jemtland or , ; Jamtish: ''Jamtlann''; la, Iemptia) is a historical province () in the centre of Sweden in northern Europe. It borders Härjedalen and Medelpad to the south, Ångermanland to the east, Lapland to the north and Trøndelag and Norway to the west. Jämtland covers an area of 34,009 square kilometres, 8.3% of Sweden's total area and is the second largest province in Sweden. It has a population of 115,331, the majority of whom live in , the area surrounding lake Storsjön. Östersund is Jämtland's only city and is the 24th most populous city in Sweden. The historical province is one of the least densely populated. Jämtland was originally an autonomous republic,Ekerwald, Carl-Göran (2004). ''Jämtarnas historia'' (in Swedish), 124.

Spitz
Spitz (derived from the German word ''spitz'' 'pointed') is a type of domestic dog characterized by long, thick, and often white fur, and pointed ears and muzzles. The tail often curls over the dog's back or droops. While all of the breeds resemble primitive dogs, smaller breeds resemble foxes, while larger breeds resemble jackals, coyotes, wolves, and even dingoes. The exact origins of spitz dogs are not known, though most of the spitzes seen today originate from the Arctic region or Siberia. The type was described as ''Canis pomeranus'' by Johann Friedrich Gmelin in his revision of ''Systema Naturae'' in 1788. Characteristics Spitzes are well suited to living in harsh northern climates. They often have an insulating, waterproof undercoat that is denser than the topcoat to trap warmth. Small, upright ears help to reduce the risk of frostbite, square proportions and thick fur that grows on the paws protects the dogs from sharp ice. Many spitz breeds, like the Japanese Akita ...

Norwegian Elkhound
The Norwegian Elkhound is one of the Northern Spitz-type breeds of dog and is the National Dog of Norway. The Elkhound has served as a hunter, guardian, herder, and defender. It is known for its courage in tracking and hunting elk and other large game, such as bears or wolves. The Norwegian Elkhound was first presented at a dog exhibition in Norway in 1877. The AKC breed name "Norwegian Elkhound" is a mistranslation from its original Norwegian name , meaning "Norwegian moose dog". In Norwegian "elg" means "moose" and "hund" means "dog," as it does in many other Germanic languages. It is Spitz breed, not a "hound" dog. The breed's object in the hunt is to independently track down and hold the moose at bay—jumping in and out toward the moose, distracting its attention, while signaling to the hunters by barking very loudly—until the hunter who follows the sound can arrive to shoot it. The dog will only bark while the moose is stationary, but it can also slowly drive the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Norwegian Elkhound
The Black Norwegian Elkhound is a small Spitz breed classified by the FCI as a hunting dog. It is very rare outside the Nordic countries of Scandinavia. It is bred for the same purpose as the Grey Norwegian Elkhound, but is smaller, more agile, and easier to recognize in the snow. Historically, it is a much "younger" breed, first bred in Norway during the 18th century. The breed name "Elkhound" comes directly from its original Norwegian name "Elghund," meaning ""elk dog" or "moose dog." In Norwegian, "elg" refers to the animal English speakers know as an "elk" (in Eurasia) or "moose" (in the United States), and "hund" means "dog." Description Appearance The Black Norwegian Elkhound is a typical Spitz breed with a short compact body, dark eyes, ears standing straight up, and a curly tail carried over the back. It has a rich coat that does not stand out from the body. This is an all-weather hunting dog and the coat is very important. It must be able to keep out the heavy aut ...

Wolf
The wolf (''Canis lupus''; : wolves), also known as the gray wolf or grey wolf, is a large canine native to Eurasia and North America. More than thirty subspecies of ''Canis lupus'' have been recognized, and gray wolves, as popularly understood, comprise wild subspecies. The wolf is the largest extant member of the family Canidae. It is also distinguished from other ''Canis'' species by its less pointed ears and muzzle, as well as a shorter torso and a longer tail. The wolf is nonetheless related closely enough to smaller ''Canis'' species, such as the coyote and the golden jackal, to produce fertile hybrids with them. The banded fur of a wolf is usually mottled white, brown, gray, and black, although subspecies in the arctic region may be nearly all white. Of all members of the genus ''Canis'', the wolf is most specialized for cooperative game hunting as demonstrated by its physical adaptations to tackling large prey, its more social nature, and its highly advanc ...

Agouti (gene)
Agouti-signaling protein is a protein that in humans is encoded by the ASIP gene. It is responsible for the distribution of melanin pigment in mammals. Agouti interacts with the melanocortin 1 receptor to determine whether the melanocyte (pigment cell) produces phaeomelanin (a red to yellow pigment), or eumelanin (a brown to black pigment). This interaction is responsible for making distinct light and dark bands in the hairs of animals such as the agouti, which the gene is named after. In other species such as horses, agouti signalling is responsible for determining which parts of the body will be red or black. Mice with wildtype agouti will be grey, with each hair being partly yellow and partly black. Loss of function mutations in mice and other species cause black fur coloration, while mutations causing expression throughout the whole body in mice cause yellow fur and obesity. The agouti-signaling protein (ASIP) is a competitive antagonist with alpha-Melanocyte-stimulating hormon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dogs
The dog (''Canis familiaris'' or ''Canis lupus familiaris'') is a domesticated descendant of the wolf. Also called the domestic dog, it is derived from the extinct Pleistocene wolf, and the modern wolf is the dog's nearest living relative. Dogs were the first species to be domesticated by hunter-gatherers over 15,000 years ago before the development of agriculture. Due to their long association with humans, dogs have expanded to a large number of domestic individuals and gained the ability to thrive on a starch-rich diet that would be inadequate for other canids. The dog has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes. Dog breeds vary widely in shape, size, and color. They perform many roles for humans, such as hunting, herding, pulling loads, protection, assisting police and the military, companionship, therapy, and aiding disabled people. Over the millennia, dogs became uniquely adapted to human behavior, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Finnish Lapphund
The Finnish Lapphund (or Finnish Lapponian Dog) – fi, Suomen Lapinkoira– is a hardy, easy going, medium-size dog breed, breed of Spitz type. Traditionally it has been used for herding reindeer. Although it is one of the most popular dog breeds in its native country, Finland, it is not very numerous outside of the Nordic countries. Lineage The breed falls under the mitochondrial DNA sub-clade referred to as d1 that is only found in northern Scandinavia. It is the result of a female wolf-male dog hybridization that occurred post-domestication. Subclade d1 originated 480–3,000 years ago and is found in all Sami people, Sami-related breeds: Finnish Lapphund, Swedish Lapphund, Lapponian Herder, Jamthund, Norwegian Elkhound and Hällefors Elkhound. The maternal wolf sequence that contributed to these breeds has not been matched across Eurasia and its branch on the phylogenetic tree is rooted in the same sequence as the 33,000 year-old Paleolithic dog#Altai dog – 33,000 B ...

Paleolithic Dog
The Paleolithic dog was a Late Pleistocene canine. They were directly associated with human hunting camps in Europe over 30,000 years ago and it is proposed that these were domesticated. They are further proposed to be either a proto-dog and the ancestor of the domestic dog or an extinct, morphologically and genetically divergent wolf population. Taxonomy One authority has classified the Paleolithic dog as ''Canis c.f. familiaris'' (where c.f. is a Latin term meaning uncertain, as in ''Canis'' believed to be ''familiaris''). Previously in 1969, a study of ancient mammoth-bone dwellings at the Mezine paleolithic site in the Chernigov region, Ukraine uncovered 3 possibly domesticated "short-faced wolves". The specimens were classified as ''Canis lupus domesticus'' (domesticated wolf). Naming In 2002, a study looked at 2 fossil skulls of large canids dated at 16,945 years before present (YBP) that had been found buried 2 metres and 7 metres from what was once a mammoth-bone hut ...

Phylogenetic Tree
A phylogenetic tree (also phylogeny or evolutionary tree Felsenstein J. (2004). ''Inferring Phylogenies'' Sinauer Associates: Sunderland, MA.) is a branching diagram or a tree showing the evolutionary relationships among various biological species or other entities based upon similarities and differences in their physical or genetic characteristics. All life on Earth is part of a single phylogenetic tree, indicating common ancestry. In a ''rooted'' phylogenetic tree, each node with descendants represents the inferred most recent common ancestor of those descendants, and the edge lengths in some trees may be interpreted as time estimates. Each node is called a taxonomic unit. Internal nodes are generally called hypothetical taxonomic units, as they cannot be directly observed. Trees are useful in fields of biology such as bioinformatics, systematics, and phylogenetics. ''Unrooted'' trees illustrate only the relatedness of the leaf nodes and do not require the ancestral root to b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
