Caribou
Reindeer (in North American English, known as caribou if wild and ''reindeer'' if domesticated) are deer in the genus ''Rangifer''. For the last few decades, reindeer were assigned to one species, ''Rangifer tarandus'', with about 10 subspecies. A 2022 revision of the genus elevated five of the subspecies to species (see Taxonomy below). They have a circumpolar distribution and are native to the Arctic, sub-Arctic, tundra, boreal forest, and mountainous regions of northern Europe, Siberia, and North America. Reindeer occur in both migratory and 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 species, the Svalbard reindeer (''R. t. platyrhynchus''), to the largest subspecies, Osborn's caribou (''R. t. osborni''). Although reindeer are quite numerous, some species and subspecies are in d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peary Caribou
The Peary caribou (''Rangifer arcticus pearyi'') is a subspecies of caribou found in the High Arctic islands of Nunavut and the Northwest Territories in Canada. They are the smallest of the North American caribou, with the females weighing an average of and the males . In length the females average and the males . Like other caribou, both the males and females have antlers. The males grow their antlers from March to August and the females from June to September, and in both cases the velvet is gone by October. The coat of the caribou is white and thick in the winter. In the summer it becomes short and darker, almost slate-grey in color. The coat is made up of hollow hair which helps to trap warmer air and insulate the caribou. The males become sexually mature after two years and the females after three years. Breeding is in the fall and depends on the female having built up sufficient fat reserves. The gestation period last for seven to eight months and one calf is produced. ...

Antler
Antlers are extensions of an animal's skull found in members of the Cervidae (deer) family. Antlers are a single structure composed of bone, cartilage, fibrous tissue, skin, nerves, and blood vessels. They are generally found only on males, with the exception of reindeer/caribou. Antlers are shed and regrown each year and function primarily as objects of sexual attraction and as weapons. In contrast to antlers, horns—found on pronghorns and bovids, such as sheep, goats, bison and cattle—are two-part structures that usually do not shed. A horn's interior of bone is covered by an exterior sheath made of keratin (the same material as human fingernails and toenails). Etymology Antler comes from the Old French ''antoillier '' (see present French : "Andouiller", from'' ant-, ''meaning before,'' oeil, ''meaning eye and'' -ier'', a suffix indicating an action or state of being) possibly from some form of an unattested Latin word ''*anteocularis'', "before the eye" (and appl ...

Northwest Territories
The Northwest Territories (abbreviated ''NT'' or ''NWT''; french: Territoires du Nord-Ouest, formerly ''North-Western Territory'' and ''North-West Territories'' and namely shortened as ''Northwest Territory'') is a federal territory of Canada. At a land area of approximately and a 2016 census population of 41,790, it is the second-largest and the most populous of the three territories in Northern Canada. Its estimated population as of 2022 is 45,605. Yellowknife is the capital, most populous community, and only city in the territory; its population was 19,569 as of the 2016 census. It became the territorial capital in 1967, following recommendations by the Carrothers Commission. The Northwest Territories, a portion of the old North-Western Territory, entered the Canadian Confederation on July 15, 1870. Since then, the territory has been divided four times to create new provinces and territories or enlarge existing ones. Its current borders date from April 1, 1999, when the ...

Reindeer In Russia
Reindeer in Russia include tundra and forest reindeer and are subspecies of ''Rangifer tarandus''. Tundra reindeer include the Novaya Zemlya (''R.t.pearsoni'') and Sápmi (''R.t. tarandus'') subspecies and the Siberian tundra reindeer (''R.t. sibiricus''). Novaya Zemlya reindeer The subspecies of reindeer, the Novaya Zemlya (''R.t.pearsoni''). on the islands of the Novaya Zemlya, were herded by the Nenets people, Nenets. Novaya Zemlya is an archipelago in the Arctic Ocean in the North of Russia and the extreme Northeast of Europe, the extreme points of Europe, easternmost point of Europe lying at Cape Flissingsky on the Northern island. The indigenous population (from 1872 to the 1950s when it was resettled to the mainland) consisted of about 50–300 Nenetses who subsisted mainly on reindeer herding, fishing, animal trapping, trapping, polar bear hunting and seal (mammal), seal hunting.

Deer
Deer or true deer are hoofed ruminant mammals forming the family Cervidae. The two main groups of deer are the Cervinae, including the muntjac, the elk (wapiti), the red deer, and the fallow deer; and the Capreolinae, including the reindeer (caribou), white-tailed deer, the roe deer, and the moose. Male deer of all species (except the water deer), as well as female reindeer, grow and shed new antlers each year. In this they differ from permanently horned antelope, which are part of a different family (Bovidae) within the same order of even-toed ungulates (Artiodactyla). The musk deer (Moschidae) of Asia and chevrotains (Tragulidae) of tropical African and Asian forests are separate families that are also in the ruminant clade Ruminantia; they are not especially closely related to Cervidae. Deer appear in art from Paleolithic cave paintings onwards, and they have played a role in mythology, religion, and literature throughout history, as well as in heraldry, such as ...

Svalbard Reindeer
The Svalbard reindeer (''Rangifer tarandus platyrhynchus'') is a small species of reindeer found on the Svalbard archipelago of Norway. Males average 65–90 kg (143-198 lb) in weight, females 53–70 kg (116-154 lb), while for other reindeer generally body mass is 159–182 kg (350-400 lb) for males and 80–120 kg (176-264 lb) for females. The species is endemic to the islands of Svalbard, where it has lived for at least 5,000 years, and has become well adapted to the harsh climate, being found on nearly all non-glaciated areas of the archipelago. By 1925 they had almost gone extinct due to over-hunting in the late 19th and early 20th centuries. Over recent decades, their population has increased. As of 2019, the total population across the archipelago is approximately 22,000. They are the only large grazing mammal in the European High Arctic, and this makes them exceptional for studies concerning the introduction of pollutants to changin ...

Genetics And Breeding Of Animals
Genetics is the study of genes, genetic variation, and heredity in organisms.Hartl D, Jones E (2005) It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring over time. He observed that organisms (pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene. Trait inheritance and molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded to study the function and behavior of genes. Gene structure and function, variation, and distribution are studied within the context of the cell, the organism (e.g. dominance), and within the cont ...
