One researcher estimated that the Swedish moose population contributed 300,000 metric tons of feces each year to the land. 5 (2005): 619-628. The division of moose into European and North American species was believed to be supported by morphological differences and evidence that European moose have 68 chromosomes and North American moose have 70. [109][110] A moose's diet often depends on its location, but they seem to prefer the new growths from deciduous trees with a high sugar content, such as white birch, trembling aspen and striped maple, among many others. [42], The moose population in New Hampshire fell from 7,500 in the early 2000s to a current[when?] [139] The males are polygamous and will seek several females to breed with. Forest types include boreal, broadleaf and mixed (coniferous-deciduous). This trait serves a second purpose in cooling down the moose on summer days and ridding itself of black flies. 652-653 in D Wilson, D Reeder, eds. Moose herbivory, browse quality, and nutrient cycling in an Alaskan treeline community. Moose have six pairs of large, flat molars and, ahead of those, six pairs of premolars, to grind up their food. It is listed under Appendix III of the Bern Convention. Alces alces Name Synonyms Alces alce Alces antiquorum Alces coronatus Alces europaeus Alces jubata Alces machilis Alces muswa Richardson, 1852 Alces palmatus Alces runnymedensis Hay, 1923 Cervus alces Linnaeus, 1758 Homonyms Alces alces (Linnaeus, 1758) Common names Alce in Spanish Alce in Portuguese Alce euroasiatico in Italian Naturaliste Canadien, 101: 393-415. Oecologia, 94: 472-479. Moose can become severely infested with winter ticks and death can sometimes result in winter as a result of blood loss and nutritional stress. Warm climates that have temperatures above 27 C for long periods likely limit their southern distribution. Male survival is more variable due to hunting and male-male competition. Predation by wolves is higher in the winter when snow depths are high enough to impede the movement of moose. Pp. It had a longer, narrower snout and a less-developed nasal cavity, more resembling that of a modern deer, lacking any sign of the modern moose-snout. Alces alces El alce (Alces alces) (en dellos llugares tamién conocíu como ante o alce) ye una especie de mamíferu artiodáctilu de la familia de los cérvidos. Pp. The black moose is (by all that have hitherto writ of it) accounted a very large creature. Bull moose use dominant displays of antlers to discourage competition and will spar or fight rivals. Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts. ranking system or pecking order among members of a long-term social group, where dominance status affects access to resources or mates. [43][44][45][46] Loss of the insulating winter coat through attempts to rid the moose of winter tick increases the risk of hypothermia in winter.[47]. Moose usually flee upon detecting wolves. Antlers take three to five months to fully develop, making them one of the fastest growing animal organs. Rutting and mating occurs in September and October. While much lower in energy, aquatic plants provide the moose with its sodium requirements, and as much as half of their diet usually consists of aquatic plant life. Telfer, Edmund S., and John P. Kelsall. (2010). Eventually, in North America the wapiti became known as an elk while the moose retained its Anglicized Native-American name. Referring to something living or located adjacent to a waterbody (usually, but not always, a river or stream). Its main value, however, is seen in the opportunities it offers for the research in the physiology and behavior of the moose, as well as in the insights it provides into the general principles of animal domestication. [132], In some areas, moose are the primary source of food for wolves. Wolves usually follow moose at a distance of 100 to 400 meters (330 to 1,310 ft), occasionally at a distance of 2 to 3 kilometers (1.2 to 1.9 mi). Soils usually subject to permafrost. (Eds.). Gestation averages about 231 days with cows giving birth to one calf on average, although twins are common. Moose hunters contribute $31 million annually to Alaska’s economy and $50 million to Canada’s. [117] Other species can pluck plants from the water too, but these need to raise their heads in order to swallow. Dr. Valerius Geist, who emigrated to Canada from the Soviet Union, wrote in his 1999 book Moose: Behaviour, Ecology, Conservation: In Sweden, no fall menu is without a mouthwatering moose dish. In Mongolia and China, where poaching took a great toll on moose, forcing them to near extinction, they are protected, but enforcement of the policy is weak and demand for traditional medicines derived from deer parts is high. 2004. 2003. The British began colonizing America in the 17th century, and found two common species of deer for which they had no names. Its face resembled that of the modern wapiti. [114] Moose are excellent swimmers and are known to wade into water to eat aquatic plants. Most moose have antlers that are broad and palmate (flat) with tines (points) along the outer edge. Males and females attract each other by making vocalizations and scent marking trees. Other bulls challenge the harem master for the right to mate. The youngest bones were found in Scotland and are roughly 3,900 years old. Moose can also be a pest to agriculture and forestry in some areas. Pp. Confirmation of this is not available due to a lack of studies, although it is known that they depend less on sight than their sense of hearing or smell. [101] The largest of all the races is the Alaskan subspecies (A. a. gigas), which can stand over 2.1 m (6.9 ft) at the shoulder, has a span across the antlers of 1.8 m (5.9 ft) and averages 634.5 kg (1,399 lb) in males and 478 kg (1,054 lb) in females. Immature bulls may not shed their antlers for the winter, but retain them until the following spring. 2000. Iteroparous animals must, by definition, survive over multiple seasons (or periodic condition changes). The largest confirmed size for this species was a bull shot at the Yukon River in September 1897 that weighed 820 kg (1,808 lb) and measured 2.33 m (7.6 ft) high at the shoulder.

Moose populations are stable at 25 calves for every 100 cows at 1 year of age. 1998. Ces animaux, dont les bois sont aplatis en éventail, sont les plus grands des cervidés actuels. Naturaliste Canadien, 101: 117-130. Farther east, it survived in Alsace and the Netherlands until the 9th century as the marshlands in the latter were drained and the forests were cleared away for feudal lands in the former. [85] Moose with antlers have more acute hearing than those without antlers; a study of trophy antlers using a microphone found that the palmate antler acts as a parabolic reflector, amplifying sound at the moose's ear. Unlike other large, hooved mammals, such as horses, moose can kick in all directions including sideways. Moose prefer sub-alpine shrublands in early winter, while bison prefer wet sedge valley meadowlands in early-winter. Its upper lip is so extremely large, for which reason it is obliged to go backwards when grazing; otherwise, by moving onwards, the lip would get doubled up. one of the sexes (usually males) has special physical structures used in courting the other sex or fighting the same sex. Journal of Wildlife Management, 57: 454-468. Cows with young calves are very protective and will attack humans who come too close, especially if they come between mother and calf. Libralces gallicus came from the warm savannas of Pliocene Europe, with the best-preserved skeletons being found in southern France. IUCN Red List of Threatened Species. scrub forests develop in areas that experience dry seasons. In the West, moose populations extend well north into Canada (British Columbia and Alberta), and more isolated groups have been verified as far south as the mountains of Utah and Colorado and as far west as the Lake Wenatchee area of the Washington Cascades. having the capacity to move from one place to another. [133] Wolf packs primarily target calves and elderly animals, but can and will take healthy, adult moose. Attempts in 1930 and again in 1967 in marshland north of Berlin were unsuccessful. Disturbance by large herbivores in Boreal forests with special reference to moose. Attacks from wolves against young moose may last seconds, though sometimes they can be drawn out for days with adults. Adult moose are in their prime from 5 to 12 years of age but begin to suffer from arthritis, dental diseases and wear, and other factors after about 8 years. Molecular Phylogenetics and Evolution, 22: 375-387. The lower prong of this fork may be either simple, or divided into two or three tines, with some flattening. Individual hairs are 15 to 25 cm long and hollow, resulting in excellent insulation. However, the antlers had a shorter horizontal bar and larger palmations, more resembling those of a modern moose. The size of the moose varies. 1999. Lundmark, Caroline. Female moose have an eight-month gestation period, usually bearing one calf, or twins if food is plentiful,[141] in May or June. 403-439 in A Franzmann, C Schwartz, eds. Journal of Mammalogy 99, no. Boulder, CO: University Press of Colorado. animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. The state agency in charge of railroad infrastructure (Jernbaneverket) plans to spend 80 million Norwegian kroner to reduce collision rate in the future by fencing the railways, clearing vegetation from near the tracks, and providing alternative snow-free feeding places for the animals elsewhere. Cervalces carnutorum was soon followed by a much larger species called Cervalces latifrons (broad-fronted stag-moose). They also have a tough tongue, lips and gums, which aid in the eating of woody vegetation. Food habits of Amur tigers in Sikhote-Alin Zapovednik and the Russian Far East, and implications for conservation. Calves can browse and follow their mother at 3 weeks old and are weaned at 5 months. Moose–train collisions were more frequent in winters with above-average snowfall. Scrafford, Matthew A., and Mark S. Boyce. Their sense of smell is exceptional due to the large surface area of their nasal cavities, which are lined with millions of sent-smelling cells. "Temporal patterns of wolverine (Gulo gulo luscus) foraging in the boreal forest." Their large bodies, inability to sweat, and the heat produced by fermentation in their guts mean they cannot tolerate temperatures exceeding 27 degrees Celsius for long. Boulder, Colorado: University Press of Colorado. Pp. Hundertmark, K., G. Shields, I. Udina, R. Bowyer, A. Danilkin, C. Schwartz. Also, as with bears or any wild animal, moose that have become used to being fed by people may act aggressively when denied food. Ecology and Management of the North American Moose. 1 sous-espèce est exclusivement européenne : ♦ Alces alcas alces : élan européen : cette sous-espèce habite la Scandinavie, la Finlande, la For this reason, they are considered to be a keystone species. Home range size of males tend to be larger than females. 173-221 in A Franzmann, C Schwartz, eds. For example: antlers, elongated tails, special spurs. "Alces alces" Outside of the rutting period, males and females are sexually segregated: males and females are separated spatially, temporally, and/or by habitat. Il y a des millions d'années, les tout premiers cervidés ne vivaient qu'en Asie. These moose were brought from Chukotka, home to the largest moose on the planet. Sa taille, mesurée au garrot, dépasse celle des plus grands chevaux de selle.

However, like all ungulates known to attack predators, the more aggressive individuals are always darker in color.[116]. It is an appropriate name because moose primarily browse upon the stems and twigs of woody plants in the winter and the leaves and shoots of deciduous plants in the summer. Historiquement le genre Alces était considéré comme monotypique, comprenant uniquement l'espèce Alces alces, elle-même divisée en plusieurs sous-espèces, mais aujourd'hui certains spécialistes proposent de considérer les populations d'Amérique du Nord et d'Eurasie comme des espèces distinctes dont les noms scientifiques respectifs seraient Alces americanus et Alces alces1. The widest spread recorded was 210 centimeters (83 in) across. They are most likely to attack if annoyed or harassed, or if approached too closely. A moose's upper lip is very sensitive, to help distinguish between fresh shoots and harder twigs, and is prehensile, for grasping their food. Its antlers were smaller than the Irish elk's, but comparable in size to those of Libralces gallicus. Miquelle, D., E. Smirnov, H. Quigley, M. Hornocker, E. Nikolaev, E. Matyushkin. 2007. Trapping elk in pits is an extremely effective hunting method. [118][119] The moose's varied and complex diet is typically expensive for humans to provide, and free-range moose require a lot of forested acreage for sustainable survival, which is one of the main reasons moose have never been widely domesticated. Males and females are sexually mature at two years of age but full growth potential isn't reached until 4 or 5 years of age. active during the day, 2. lasting for one day. The daily pattern is traveling to a new site to feed, avoiding predators, browsing on plants, standing, and lying down for the rumination of their food. Both sexes are capable of making a loud, guttural “roaring” sound as a threat. Moose are crepuscular by nature, being most active at sunrise and sunset. National Science Foundation (Wilson and Ruff, 1999), Moose are hunted throughout much of their range and provide millions of pounds in meat to humans each year. Moose are not usually aggressive towards humans, but can be provoked or frightened to behave with aggression. (Eurasian elk should not be confused with North American elk, Cervus canadensis, which are a different species.) 67. [48][49] Unsuccessful thus far in recolonizing these areas via natural dispersal from source populations in Poland, Belarus, Ukraine, Czech Republic and Slovakia, it appears to be having more success migrating south into the Caucasus. © 2020 Regents of the University of Michigan. "Larver av nässtyngfluga i ögat - ovanligt men allvarligt problem. Ils étaient armés de défenses pour se battre, mais les élans les perdirent au cours de l'évolution pour acquérir les bois immenses et spectaculaires qui les caractérisent désormais dans le règne animal. [123] Brown bears (Ursus arctos)[102] are also known to prey on moose of various sizes and are the only predator besides the wolf to attack moose both in Eurasia and North America. An all-white color phase is rare. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Some moose migrate seasonally, up to 179 km in North America and 300 km in northeastern Europe. Biogeography of moose with particular reference to western North America. 2001. (3 months)Calves stay near their mothers at all times. During the fall mating season, bulls may be aggressive toward humans because of the high hormone levels they experience. Pp. Alces alces alces Myre Norway From Denali National Park. 2007. These migrations can exceed 300km in European populations. offspring are produced in more than one group (litters, clutches, etc.) Also, cows with calves at heel seclude themselves from conspecifics to reduce the risk of being singled out by predators. By September the velvet is removed by rubbing and thrashing which changes the colour of the antlers. In Europe, moose are currently found in large numbers throughout Norway, Sweden, Finland, Latvia, Estonia, Poland, with more modest numbers in the southern Czech Republic, Belarus and northern Ukraine. [23] This is the southernmost naturally established moose population in the United States. In practical terms this means moose are more vulnerable in areas where wolf or bear populations were decimated in the past but are now rebounding. ADW doesn't cover all species in the world, nor does it include all the latest scientific information about organisms we describe. 1_supplement (2019): 767-19. With availability of adequate nutrition, mild weather, and low predation, moose have a huge potential for population expansion.[143]. 15 déc. [107], Moose lack upper front teeth, but have eight sharp incisors on the lower jaw. An Alces alces in nahilalakip ha genus nga Alces, ngan familia nga Cervidae. Antler beam diameter, not the number of tines, indicates age. A moose of either sex that is confronted by danger may let out a loud roar, more resembling that of a predator than a prey animal. Pp. Wild mammals of North America: Biology, management and conservation. [27] Moose reestablished populations in eastern New York and Connecticut and appeared headed south towards the Catskill Mountains, a former habitat. Pagano, Anthony Santino, Jeffrey T. Laitman, Kurt Albertine, and Samuel Marquez. Coniferous or boreal forest, located in a band across northern North America, Europe, and Asia. Karns, P. 2007. Moose meat tastes, wrote Henry David Thoreau in "The Maine Woods", "like tender beef, with perhaps more flavour; sometimes like veal". Alces, 40: 103-122. 4 (2009): 270-278. [17], After expanding for most of the 20th century, the moose population of North America has been in steep decline since the 1990s. Pp. The Pleistocene epoch was a time of gigantism, in which most species were much larger than their descendants of today, including exceptionally large lions, hippopotamuses, mammoths, and deer. 2007. Remains of wooden fences designed to guide the animals toward the pits have been found in bogs and peat. Population distribution, density, and trends. This equals about 5,600 tons of nitrogen, which is essential for plant growth. Walker's Mammals of the World. [170], In eastern Germany, where the scarce population is slowly increasing, there were two road accidents involving moose since 2000.[50]. [137], Moose are also subject to various diseases and forms of parasitism. Il possède un nez large, une petite queue, de longues pattes, un cou assez court, des sabots élargis et palmés. Trends in Ecology & Evolution, 13: 58-63. "[84] This requires intense grazing on a highly-nutritious diet. In North America, moose have been observed to consume as many as 221 plant species and genera, and in Russia 355, although only a select few comprise a significant portion of their diet. from a high of 5,000 animals in 2005. Smith, A. T., Xie, Y., Hoffmann, R. S., Lunde, D., MacKinnon, J., Wilson, D. E., & Wozencraft, W. C. Moose have very acute hearing due in part to the large external surface area of their ears. [86], The antlers of mature Alaskan adult bull moose (5 to 12 years old) have a normal maximum spread greater than 200 centimeters (79 in). Pp. Le genre Alces était autrefois considéré comme étant monotypique, mais des études récentes ont démontré que l'orignal et l'élan d'Eurasie sont en fait deux espèces bien distinctes In northern Europe, the moose botfly is a parasite whose range seems to be spreading.[138]. Moose migrations in North America. Moose d'Alaska - Alces Alces Le moose d'Alaska est un mammifère appelé élan en Europe ou orignaux au Canada. Annales Zoologici Fennici 44, no. Food habits and feeding behavior. DESCRIPTION. Annales Zoologici Fennici, 37: 251-263. The status and management of moose in North America circa 2000-01. Birds, carnivores and rodents eat dropped antlers as they are full of protein and moose themselves will eat antler velvet for the nutrients. In the Americas, moose injure more people than any other wild mammal, and worldwide, only hippopotamuses injure more. They inhabit the taiga and temperate forest biomes, including the tundra-subalpine zone. Some scientists, such as Adrian Lister, grouped all the species into one genus, while others, such as Augusto Azzaroli, used Alces for the living species, placing the fossil species into the genera Cervalces and Libralces. having markings, coloration, shapes, or other features that cause an animal to be camouflaged in its natural environment; being difficult to see or otherwise detect. However the consumption of moose liver or kidneys significantly increased cadmium intake, with the study revealing that heavy consumers of moose organs have a relatively narrow safety margin below the levels which would probably cause adverse health effects. (Eurasian elk should not be confused with North American elk, Cervus canadensis, which are a different species.) Ecology and Management of the North American Moose. Taxon Information L'Orignal (Alces alces Americana) Orignal mâle: Orignal femelle: Description : L’orignal mâle adulte, doté de son panache complet, est l’animal le plus imposant de l’Amérique du Nord. Alaskan moose have been reported to successfully fend off attacks from both black and brown bears. This in turn means that the cow moose has at least a small degree of control over which bulls she mates with. En Amérique du Nord, l'aire de répartition des orignaux comprend presque … The moose is a browsing herbivore and is capable of consuming many types of plant or fruit. Calves are born at an average weight of 16.2 kg and gain approximately 1 kg per day while they are nursing. In otherwords, Europe and Asia and northern Africa. Incidental mortality. (Bowyer, et al., 2003; Franzmann, 1981; Renecker and Schwartz, 2007), Wolves, brown or grizzly bears, black bears, and cougars are major predators of moose, and to a lesser extent coyotes and Amur tigers. Henttonen, H., M. Stubbe, T. Maran, A. Tikhonov. [166][167] Newfoundland and Labrador recommended that motorists use caution between dusk and dawn because that is when moose are most active and most difficult to see, increasing the risk of collisions. living in the Nearctic biogeographic province, the northern part of the New World. Home range, dispersal and migration. 2008, no. 6 (1984): 1828-1834. [159], The center of mass of a moose is above the hood of most passenger cars. Upper Saddle River, NJ: Prentice-Hall. Following Bergmann's rule, population in the south (A. a. cameloides) usually grow smaller, while moose in the north and northeast (A. a. buturlini) can match the imposing sizes of the Alaskan moose (A. a. gigas) and are prized by trophy hunters. [55] The last proven sighting of a moose in New Zealand was in 1952. gonochoric/gonochoristic/dioecious (sexes separate), maternal position in the dominance hierarchy affects status of young, body parts are source of valuable material, Ecology and Management of the North American Moose, Wild mammals of North America: Biology, management and conservation, Ecology and management of large mammals in North America, Mammal species of the world: a taxonomic and geographic reference, Ecology and management of the North American moose, Mammal community dynamics in western coniferous forests: Management and conservation, Ecology and management of North American moose, The Smithsonian Book of North American Mammals. Boulder, Colorado: University Press of Colorado. Moose are the only deer that are capable of feeding underwater. 1998. Alces, 39: 131-151. Thus, the moose's digestive system has evolved to accommodate this relatively low-fiber diet. [90][89], As with all members of the order Artiodactyla (even-toed ungulates), moose feet have two large keratinized hooves corresponding to the third and fourth toe, with two small posterolateral dewclaws (vestigial digits), corresponding to the second and fifth toe. [108] A typical moose, weighing 360 kg (794 lb), can eat up to 32 kg (71 lb) of food per day. [50][51], In 2008, two moose were reintroduced into the Scottish Highlands[52][53] in Alladale Wilderness Reserve.[54]. Additional support has come from the Marisla Foundation, UM College of Literature, Science, and the Arts, Museum of Zoology, and Information and Technology Services. For larger trees a moose may stand erect and walk upright on its hind legs, allowing it to reach branches up to 4.26 meters (14.0 ft) or higher above the ground.[112][113]. Hayward, M. W., Jędrzejewski, W., & Jedrzejewska, B. Voir plus d'idées sur le thème animaux, animaux sauvages, orignal. Moose also require access to mineral licks, safe places for calving and aquatic feeding sites.
