Elk

The elk (pl.: elk or elks; Cervus canadensis) or wapiti, is the second largest species within the deer family, Cervidae, and one of the largest terrestrial mammals in its native range of North America and Central and East Asia. The word "elk" originally referred to the European variety of the moose, Alces alces, but was transferred to Cervus canadensis by North American colonists.

The name "wapiti" is derived from a Shawnee and Cree word meaning "white rump", after the distinctive light fur around the tail region which the animals may fluff-up or raise to signal their agitation or distress to one another, when fleeing perceived threats, or among males courting females and sparring for dominance. A similar trait is seen in other artiodactyl species, like the bighorn sheep, pronghorn and the white-tailed deer, to varying degrees.

Elk dwell in open forest and forest-edge habitats, grazing on grasses and sedges and browsing higher-growing plants, leaves, twigs and bark. Male elk have large, blood- and nerve-filled antlers, which they routinely shed each year as the weather warms. Males also engage in ritualized mating behaviors during the mating season, including posturing to attract females, antler-wrestling (sparring), and bugling, a loud series of throaty whistles, bellows, screams, and other vocalizations that establish dominance over other males and aim to attract females.

Elk were long believed to belong to a subspecies of the European red deer (Cervus elaphus), but evidence from many mitochondrial DNA genetic studies, beginning in 1998, shows that the two are distinct species. The elk's wider rump-patch and paler-hued antlers are key morphological differences that distinguish C. canadensis from C. elaphus. Although it is currently only native to North America, and Central, East and North Asia, elk once had a much wider distribution in the past; prehistoric populations were present across Eurasia and into Western Europe during the Late Pleistocene, surviving into the early Holocene in Southern Sweden and the Alps. The now-extinct North American Merriam's elk subspecies (Cervus canadensis merriami) once ranged south into Mexico. The wapiti has also successfully adapted to countries outside of its natural range where it has been introduced, including Argentina and New Zealand; the animal's adaptability in these areas may, in fact, be so successful as to threaten the sensitive endemic ecosystems and species it encounters.

As a member of the Artiodactyla order (and distant relative of the Bovidae), elk are susceptible to several infectious diseases which can be transmitted to or from domesticated livestock. Efforts to eliminate infectious diseases from elk populations, primarily by vaccination, have had mixed success. Some cultures revere the elk as having spiritual significance. Antlers and velvet are used in traditional medicines in parts of Asia; the production of ground antler and velvet supplements is also a thriving naturopathic industry in several countries, including the United States, China and Canada. The elk is hunted as a game species, and their meat is lean and higher in protein than beef or chicken.

By the 17th century, Alces alces (moose, called "elk" in Europe) had long been extirpated from the British Isles, and the meaning of the word "elk" to English-speakers became rather vague, acquiring a meaning similar to "large deer". The name wapiti is from the Shawnee and Cree word waapiti (in Cree syllabics: ᐙᐱᑎ or ᐚᐱᑎ), meaning "white rump". There is a subspecies of wapiti in Mongolia called the Altai wapiti (Cervus canadensis sibiricus), also known as the Altai maral.

According to the Oxford English Dictionary, the etymology of the word "elk" is "of obscure history". In Classical Antiquity, the European Alces alces was known as Ancient Greek: ἄλκη, romanized: álkē and Latin: alces, words probably borrowed from a Germanic language or another language of northern Europe. By the 8th century, during the Early Middle Ages, the moose was known as Old English: elch, elh, eolh, derived from the Proto-Germanic: *elho-, *elhon- and possibly connected with the Old Norse: elgr. Later, the species became known in Middle English as elk, elcke, or elke, appearing in the Latinized form alke, with the spelling alce borrowed directly from Latin: alces. Noting that elk "is not the normal phonetic representative" of the Old English elch, the Oxford English Dictionary derives elk from Middle High German: elch, itself from Old High German: elaho.

The American Cervus canadensis was recognized as a relative of the red deer (Cervus elaphus) of Europe, and so Cervus canadensis were referred to as "red deer". Richard Hakluyt refers to North America as a "lande ... full of many beastes, as redd dere" in his 1584 Discourse Concerning Western Planting. Similarly, John Smith's 1616 A Description of New England referred to red deer. Sir William Talbot's 1672 English translation of John Lederer's Latin Discoveries likewise called the species "red deer", but noted in parentheses that they were "for their unusual largeness improperly termed Elks by ignorant people". Both Thomas Jefferson's 1785 Notes on the State of Virginia and David Bailie Warden's 1816 Statistical, Political, and Historical Account of the United States used "red deer" to refer to Cervus canadensis.
