⭐ Core Definition: Reindeer

The reindeer or caribou (Rangifer tarandus) is a species of deer with circumpolar distribution, native to Arctic, subarctic, tundra, 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 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 in the context of 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.

Reindeer in the context of Pastoralism

Pastoralism is a form of animal husbandry where domesticated animals (known as "livestock") are released onto large vegetated outdoor lands (pastures) for grazing, historically by nomadic people who moved around with their herds. The animal species involved include cattle, camels, goats, yaks, llamas, reindeer, horses, and sheep.

Pastoralism occurs in many variations throughout the world, generally where environmentally effected characteristics such as aridity, poor soils, cold or hot temperatures, and lack of water make crop-growing difficult or impossible. Operating in more extreme environments with more marginal lands means that pastoral communities are very vulnerable to the effects of global warming.

Reindeer in the context of Nomadic pastoralism

Nomadic pastoralism, also known as nomadic herding, is a form of pastoralism in which livestock are herded in order to seek for fresh pastures on which to graze. True nomads follow an irregular pattern of movement, in contrast with transhumance, where seasonal pastures are fixed. However, this distinction is often not observed and the term 'nomad' used for both—and in historical cases the regularity of movements is often unknown in any case. The herded livestock include cattle, water buffalo, yaks, llamas, sheep, goats, reindeer, horses, donkeys or camels, or mixtures of species. Nomadic pastoralism is commonly practiced in regions with little arable land, typically in the developing world, especially in the steppe lands north of the agricultural zone of Eurasia. Pastoralists often trade with sedentary agrarians, exchanging meat for grains; however, they have been known to raid.

Of the estimated 30–40 million nomadic pastoralists worldwide, most are found in central Asia and the Sahel region of North and West Africa, such as Fulani, Tuaregs, and Toubou, with some also in the Middle East, such as traditionally Bedouins, and in other parts of Africa, such as Nigeria and Somalia. Increasing numbers of stock may lead to overgrazing of the area and desertification if lands are not allowed to fully recover between one grazing period and the next. Increased enclosure and fencing of land has reduced the amount of land for this practice.

Reindeer in the context of Reindeer herders

Reindeer herding is when reindeer are herded by people in a limited area. Currently, reindeer are the only semi-domesticated animal which naturally belong to the North. Reindeer herding is conducted in nine countries: Norway, Finland, Sweden, Russia, Greenland, the United States (Alaska), Mongolia, China and Canada. A small herd is also maintained in Scotland's Cairngorms National Park.

Reindeer herding is conducted by individuals within some kind of cooperation, in forms such as families, districts, Sámi and Yakut villages and sovkhozy (collective farms). A person who conducts reindeer herding is called a reindeer herder and approximately 100,000 people are engaged in reindeer herding today around the circumpolar North.

Reindeer in the context of Magdalenian

Magdalenian cultures (also Madelenian; French: Magdalénien) are later cultures of the Upper Paleolithic and Mesolithic in western Europe. They date from around 17,000 to 12,000 years before present. It is named after the type site of Abri de la Madeleine, a rock shelter (abri) located in the Vézère valley of Tursac in Dordogne, France.

Édouard Lartet and Henry Christy originally termed the period L'âge du renne "the age of the reindeer". They conducted the first archaeological excavation of the type site, publishing in 1875. The Magdalenian is associated with reindeer hunters. Magdalenian sites contain extensive evidence for the hunting of red deer, wild horses, and other megafauna present in Europe toward the end of the Last Glacial Period. The culture was geographically widespread, and later Magdalenian sites stretched from Portugal in the west to Poland in the east, and as far north as France, the Channel Islands, England, and Wales. Besides la Madeleine, the chief stations of the Magdalenian are Les Eyzies, Laugerie-Basse, and Gorges d'Enfer in the Dordogne; Grotte du Placard in Charente and others in Southwest France.

Reindeer in the context of Karaginsky Island

Karaginsky Island or Karaginskiy Island (Russian: Карагинский остров) is an island in the Karaginsky Gulf of the Bering Sea. The 40-kilometre (25 mi)-wide strait between the Kamchatka Peninsula and this island is called Litke Strait. Karaginsky Island is a Ramsar site. Even though the island is uninhabited, the Karagin Koryaks have traditionally lived in Karaginskiy Island. Migrant reindeer herders still live in temporary shelters on the island.

The island is 101 km (63 mi) long and up to 27 km (17 mi) wide, with an area of 193,597 ha (1,935.97 km; 747.48 sq mi). The highest peak of the island is 912 m (2,992 ft). Karaginsky Island is covered with tundra vegetation and cedar underwood. In the summer, there are many flowers.

Reindeer in the context of Enontekiö

Enontekiö (Finnish: [ˈenontekiø]; Northern Sami: Eanodat [ˈe̯anoðah(t)]; Swedish: Enontekis; Inari Sami: Iänudâh; Skolt Sami: Jeänõk) is a municipality in the Finnish part of Lapland with approximately 1,800 inhabitants. It is situated in the outermost northwest of the country and occupies a large and very sparsely populated area of about 8,400 square kilometres (3,200 sq mi) between the Swedish and Norwegian border. Finland's highest point, the Halti fell, with a height of 1,324 metres (4,344 ft) above the mean sea level, is situated in the north of Enontekiö. The municipality shares borders with regions of Sweden and Norway that encompass the Scandinavian Mountains. The administrative centre of Enontekiö is the village of Hetta. About one fifth of the community's population are Sami people. Enontekiö's main industries are tourism and reindeer husbandry.

Reindeer in the context of Late Pleistocene megafauna extinctions

The Late Pleistocene to the beginning of the Holocene saw the extinction of the majority of the world's megafauna, typically defined as animal species having body masses over 44 kg (97 lb), which resulted in a collapse in faunal density and diversity across the globe. The extinctions during the Late Pleistocene are differentiated from previous extinctions by their extreme size bias towards large animals (with small animals being largely unaffected), the widespread absence of ecological succession to replace these extinct megafaunal species, and the regime shift of previously established faunal relationships and habitats as a consequence. The timing and severity of the extinctions varied by region and are generally thought to have been driven by humans, climatic change, or a combination of both. Human impact on megafauna populations is thought to have been driven by hunting ("overkill"), as well as possibly environmental alteration. The relative importance of human vs climatic factors in the extinctions has been the subject of long-running controversy, though some sources suggest that most scholars support at least a contributory role of humans in the extinctions.

Major extinctions occurred in Australia-New Guinea (Sahul) beginning around 50,000 years ago and in the Americas about 13,000 years ago, coinciding in time with the early human migrations into these regions. Extinctions in northern Eurasia were staggered over tens of thousands of years between 50,000 and 10,000 years ago, while extinctions in the Americas were virtually simultaneous, spanning only 3,000 years at most. Overall, during the Late Pleistocene about 65% of all megafaunal species worldwide became extinct, rising to 72% in North America, 83% in South America and 88% in Australia, with all mammals over 1,000 kg (2,200 lb) becoming extinct in Australia and the Americas, and around 80% globally. Africa, South Asia, and Southeast Asia experienced more moderate extinctions than other regions.

Reindeer in the context of Mammoth steppe

The mammoth steppe, also known as steppe-tundra, was once the Earth's most extensive biome. During glacial periods in the later Pleistocene, it stretched east to west from the Iberian Peninsula in the west of Europe, then across Eurasia and through Beringia (the region including the far northeast of Siberia, Alaska and the now submerged land between them) and into the Yukon in northwest Canada; from north to south, the steppe reached from the Arctic southward to southern Europe, Central Asia and northern China. The mammoth steppe was cold and dry, and relatively featureless—though climate, topography, and geography varied considerably throughout. Certain areas of the biome, such as coastal areas, had wetter and milder climates than others. Some areas featured rivers which through erosion naturally created gorges, gulleys, or small glens. The continual glacial recession and advancement over millennia contributed more to the formation of larger valleys and different geographical features. Overall, however, the steppe is known to be flat and expansive grassland. The vegetation was dominated by palatable, high-productivity grasses, herbs and willow shrubs. Although it was primarily a Eurasian and Beringian biome, an analog of the mammoth steppe existed on the southern edge of the Laurentide ice sheet in North America as well, and contained many of the same animals such as woolly mammoths, muskoxen, scimitar cats, and caribou.

The fauna was dominated by species such as reindeer, muskox, saiga antelope, steppe bison, horses, woolly rhinoceros and woolly mammoth. These herbivores, in turn, were followed and preyed upon by various carnivores, such as wolves, brown bears, Panthera spelaea (the cave or steppe-lion), cave hyenas, wolverines, among others, as well as scimitar-toothed cats and giant short-faced bears in east Beringia (with scimitar-toothed cats also having rare records from the mammoth steppe in Eurasia).

Reindeer in the context of Reindeer moss

Cladonia rangiferina, also known as reindeer cup lichen, reindeer lichen (cf. Sw. renlav) or grey reindeer lichen, is a light-coloured fruticose, cup lichen species in the family Cladoniaceae. It grows in both hot and cold climates in well-drained, open environments. Found primarily in areas of alpine tundra, it is extremely cold-hardy.

Other common names include reindeer moss, deer moss, and caribou moss, but these names can be misleading since it is, though somewhat moss-like in appearance, not a moss. As the common names suggest, reindeer lichen is an important food for reindeer (caribou), and has economic importance as a result. Synonyms include Cladina rangiferina and Lichen rangiferinus.

Reindeer in the context of Cervidae

A deer (pl.: deer) or true deer is a hoofed ruminant ungulate of the family Cervidae (informally the deer family). Cervidae is divided into subfamilies Cervinae (which includes, among others, muntjac, elk (wapiti), red deer, and fallow deer) and Capreolinae (which includes, among others reindeer (caribou), white-tailed deer, roe deer, and moose). Male deer of almost all species (except the water deer), as well as female reindeer, grow and shed new antlers each year. These antlers are bony extensions of the skull and are often used for combat between males.

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.

Reindeer in the context of Edgeøya

Edgeøya (Norwegian: [ˈɛdʒˌœ͡ʏɑ]), anglicised as Edge Island, is a Norwegian island located in southeast of the Svalbard archipelago; with an area of 5,073 square kilometres (1,960 sq mi), it is the third-largest island in this archipelago. An Arctic island, it forms part of the Søraust-Svalbard Nature Reserve, home to polar bears and reindeer. An ice field covers its eastern side. The island takes its name from Thomas Edge (died 1624), an English merchant and whaler. It is seldom visited today and development of tourist facilities is forbidden by law because of its nature reserve status.

Reindeer in the context of Tautavel Man

Tautavel Man refers to the archaic humans which—from approximately 550,000 to 400,000 years ago—inhabited the Caune de l’Arago, a limestone cave in Tautavel, France. They are generally grouped as part of a long and highly variable lineage of transitional morphs which inhabited the Middle Pleistocene of Europe, and would eventually evolve into the Neanderthals (Homo neanderthalensis or H. sapiens neanderthalensis). They have been variably assigned to either H. (s.?) heidelbergensis, or as a European subspecies of H. erectus as H. e. tautavelensis. The skull is reconstructed based on the specimens Arago 21 and 47 (probably male), and it is, to a degree, more characteristic of what might be considered a typical H. erectus (sensu stricto) morphology than a typical H. heidelbergensis morphology. The brain capacity is 1,166 cc. They seem to have had an overall robust skeleton. Average height may have been 166 cm (5 ft 5 in).

The Caune de l'Arago opens on a cliffside 80 m (260 ft) above a river, overlooking the Tautavel plain, with a plateau above, and mountainous terrain to the sides. During and after human occupation, the area swung from temperate and humid forestland, to cold and dry steppeland. Stratigraphically, humans are present from beds Q–C. Bed G, dating to roughly 455,000 years old during a forested event, has yielded the most remains. They seem to have hunted a variety of animals, including red deer, fallow deer, argali, tahr, horse, reindeer, beaver, and the extinct narrow-nosed rhinoceros, among others. They made Acheulean stone tools, but mainly produced smaller retouched tools such as scrapers, rather than more iconic macro-tools such as bifaces (hand axes). In beds G and F, they may have been practicing ritual cannibalism. Evidence of fire is absent until bed C (400,000 years ago).

Reindeer in the context of Milking

Milking is the act of removing milk from the mammary glands of cattle, water buffalo, humans, goats, sheep, and, more rarely, camels, horses, and donkeys. Milking may be done by hand or by machine, and requires the animal to be currently or recently pregnant. The milker may refer either to the animal that produces the milk or the person who milks said animal.

Reindeer in the context of Cairngorms

The Cairngorms (Scottish Gaelic: Am Monadh Ruadh) are a mountain range in the eastern Highlands of Scotland closely associated with the mountain Cairn Gorm. The Cairngorms became part of Scotland's second national park (the Cairngorms National Park) on 1 September 2003. Although the Cairngorms give their name to, and are at the heart of, the Cairngorms National Park, they only form one part of the national park, alongside other hill ranges such as the Angus Glens and the Monadhliath, and lower areas like Strathspey.

The Cairngorms consists of high plateaux at about 1,000–1,200 m (3,300–3,900 ft) above sea level, above which domed summits (the eroded stumps of once much higher mountains) rise to around 1,300 m (4,300 ft). Many of the summits have tors, free-standing rock outcrops that stand on top of the boulder-strewn landscape. In places, the edges of the plateau form steep cliffs of granite and they are excellent for skiing, rock climbing and ice climbing. The Cairngorms form an arctic-alpine mountain environment, with tundra-like characteristics and long-lasting snow patches. This area is home to bird species such as ptarmigan, dotterel, snow bunting, curlew and red grouse, as well as mammals such as mountain hare. The plateau also supports Britain's only herd of reindeer (albeit semi-domesticated). Surrounding the central massif are many remnants of the Caledonian forest in straths and glens of the Rivers Spey and Dee. These forests support many species that are rare elsewhere in Britain, including red squirrels, pine marten, wood ants, Scottish crossbill, capercaillie and crested tit.
