Elk

 

The Life of Animals | Elk | Early European explorers in North America, who were with the smaller deer Europe think more North America animals such as moose, elk and therefore the name of that is the name of common European elk. Moose is the word American elk Norse, Scandinavian Elgr ELG / elk ALG and German, all of which to the animal in North America known as Moose relate the following. This name will be used primarily for the Asian subspecies (Altai wapiti, Tian Shan wapiti, moose Manchuria and Alashan wapiti), moose Eurasia, because the name is still used by moose. Especially on Caspian red deer (Cervus elaphus maral), a subspecies of deer It is a subspecies of elk in Mongolia called the Altai wapiti (Cervus canadensis sibiricus), also known as maral Altai, Siberia Siberia known moose or elk. Populations vary in shape and size of timber behavior, body size, coloration and mating.


Of the six subspecies of elk known inhabited North America in historical times have four remain, including the Roosevelt (C. canadensis roosevelti), Tule (C. canadensis nannodes), Manitoba (C. canadensis manitobensis) and Rocky Mountain (C. canadensis nelsoni ). Eastern subspecies of elk (C. canadensis) and Merriam Elk (C. canadensis merriami) were described disappeared for at least a four subspecies in Asia are the century Altai Wapiti (C. canadensis sibiricus) and the Tianshan Wapiti (C. canadensis songaricus). Two different subspecies in China and Korea are the Manchurian wapiti (C. canadensis xanthopygus) and Alashan wapiti (C. canadensis alashanicus). The Manchurian wapiti is darker and redder the other populations. Alashan wapiti of north central China is the smallest of all subspecies, has the lightest coloration and is the least investigated. Biologist Valerius Geist, who wrote about the different species of deer in the world, said that there are only three subspecies of elk.


Recent studies suggest that it is not the DNA of more than three or four subspecies of elk. All American forms appear to belong to a subspecies (Cervus canadensis canadensis). Also Siberian elk (Cervus canadensis sibiricus) are more or less identical to the American forms and therefore belong to the subspecies, also. However the Manchurian wapiti (Cervus canadensis xanthopygus) is significantly different differ from the shape Siberia, but not from the Alashan wapitiThe Chinese subspecies are sometimes considered separate species, namely the Asian red deer (Cervus wallichi), which also deals with deer Kashmir Adult elk usually stay in single-sex groups for most of the year. If no bull back, grab the timber and fight bulls sometimes erect serious injury. Dominant bulls follow groups of cows during the rut, from August to early winter. A bull will defend his harem of 20 cows or bulls against rivals and enemies. Only males have large harems and breeding success peaks at the age of eight years. Toros young adults keep a harem later in the breeding season than bulls in their prime. A bull can with a harem rarely feeds and lose up to 20 percent of their body weight. When the females are ready to give birth, they tend to isolate themselves from the herd and remain isolated until the calf is large enough to escape predators. Elk calves are as big as an adult white-tailed deer at the age of six months. The gestation period is the same for all subspecies. Elk live 20 years or more in captivity but average 10 to 13 years in the wilderness. Coyote packs feed primarily on elk calves, but sometimes a weakened adult winter. In the vast Yellowstone ecosystem, including Yellowstone National Park, bears are major predators of calves. The main enemies in Asia are the wolf, dhole, brown bear, Siberian tiger, Amur Leopard and Snow Leopard. Lynx and wild boars sometimes hunt for Asian elk calves. Male elk retain their antlers for more than half of the year and are less likely to group with other males when they have antlers.


After the routine, women form large herds of up to 50 people. As is the case with many species of deer, especially in the mountainous regions, elk migrate to higher altitudes is in the spring after snow fell, and the opposite direction in the fall. Hunting pressure also impacts on migration and movements. Roosevelt Elk are usually settled by less seasonal variability of food sources. Numbers Yellowstone elk herd large ecosystem of more than 200,000 people in the spring and fall, to participate in the longest elk migration in the continental U.S. Elk in the south of Yellowstone National Park and national forest around south of the town of Jackson, Wyoming, where the winter for a maximum of six months in the National Elk Refuge. Environmentalists will ensure the herd is fed well in the harsh winters. A large number of elk that live in the ecosystem of the northern Greater Yellowstone lower elevations in Montana to migrate mainly in the north and west. Elk have played an important role in the cultural history of the peoples. Pictographs and petroglyphs of elk were carved into cliffs thousands of years ago by the Anasazi of the southwestern United States youngest Indian tribes, including the Kootenai, Cree, Blackfeet, Ojibwa and Pawnee, produced blankets and fur robes moose. At birth, Lakota men were to promote elk tooth for a long life because it's too bad as the last piece of dead moose. The moose is considered a high level of sexual activity and young Lakota men who had dreamed of elk an image of the mythical representation of the dynamics in their "hands" on the court as a sign of sexual potency have. Neolithic rock carvings from Asia are fewer female moose antlers, which was interpreted as a symbol of rebirth and food. The Rocky Mountain Elk is the official animal of the State of Utah. A picture of a moose and a moose on the state flag of Michigan appear. The Benevolent and Protective Order of Elks (BPOE) chose the elk as its namesake, as many of its attributes seemed appropriate for the culture of fraternity members.


Elk kept in captivity or kept for the production of venison and velvet collection. All Asian subspecies, as well as other deer have been for their antlers in central and eastern Asia by Han Chinese, Turkic peoples, Tungusic peoples, Mongolians and Koreans raised. Elk farms are relatively common in North America and New Zealand. Modern applications are decorative, but elk skin shoes, gloves and belts are not uncommon. Since 1967, the Boy Scouts of America at the National Elk Refuge staff have assisted in Wyoming by collecting wood that are made every winter. In 2010 2.520 kg (5600 pounds) auction of wood, bringing more than $ 46,000.

Groundhog

 

The Life of Animals | Groundhog  | The higher is the marmot Sciuridae in its geographical area, usually 40-65 cm (16-26 inches) long (including 15 cm (6 inches) from the tail) and weighing 2 to 4 kg (4-9 lb). In regions with less natural predators and large amounts of alfalfa, groundhogs can grow to 80 cm (30 inches) and 14 kg (31 lbs). Groundhogs are well adapted for digging, with short limbs, yet powerful curved claws thick. Adapted to the temperate habitat, groundhogs are covered with two layers of fur: a dense gray long coat and a bunch of guard hairs that gives the groundhog its distinctive "frozen".

Groundhogs are well adapted for digging, with short limbs, yet powerful curved claws thick. Adapted to the temperate habitat, groundhogs are covered with two layers of fur: a dense gray long coat and a bunch of guard hairs that gives the groundhog its distinctive "frozen".


Groundhogs are well adapted for digging, with short limbs, yet powerful curved claws thick. Groundhogs are excellent burrowers, with burrows for sleeping, rearing young, and hibernating. The average groundhog has been estimated to move approximately 1 m3 (35 cubic feet) or 320 kg (710 lb) ground by digging a burrow. Although groundhogs are the most solitary of the marmots, several individuals may occupy the same burrow. Groundhog burrows usually have 2-5 inputs, providing groundhogs principal means of escape from predators. Groundhogs are one of the few species that enter into true hibernation, and often build a "winter burrow" for this purpose separate.


Groundhogs are most of the time during the day. Groundhogs may squeal when fighting, seriously injured or captured by the enemy. Others sounds groundhogs may make are low barks and a sound produced by the grinding of teeth when groundhogs are frightened, the hairs of the tail support, giving the tail looks like a hair brush The breeding season runs from early March to mid or late April, after hibernation. Litter is produced annually, usually containing 5:58-blind, hairless and helpless young. Marmot young are weaned and ready to seek their own burrow 5-6 weeks of age. The groundhog prefers open country and the edges of forests, and rarely far from a burrow entrance.


Groundhogs are often hunted for sport, which tends to control their numbers. Marmots bred in captivity can be socialized relatively easily, but their aggressive nature can pose problems. Doug Schwartz, a zookeeper and groundhog trainer Staten Island Zoo, was quoted as saying. United States and Canada, the annual Groundhog Day gave the recognition and popularity of the marmot, like in the movie of the same name. The best known of these groundhogs are Wiarton Willie and Punxsutawney Phil, well maintained, as part of celebrations of Groundhog Day in Wiarton, Ontario and Punxsutawney, Pennsylvania, respectively. A marmot famous south, General Beauregard Lee, is based on the Yellow River Game Ranch outside Atlanta, Georgia.


Marmots are used in medical research on liver cancer induced hepatitis B. Marmot burrows have been known to be at least one archaeological site, the site Ufferman in the state of Ohio, United States Although archaeologists have excavated the Ufferman site, many objects were found through activities local marmots.

Sailfish

 

The Life of Animals | Sailfish | Both species grow rapidly sailboats, reaching 1.2 to 1.5 m (3 ft. 10 in.-4 ft. 10 in.) in length in a single year, and feed on the surface or deep medium and small pelagic feed on squid. This tactic has also been observed during feeding, when a group of sailboat sails use "herd" a school of fish or squid.


Sailfish are highly prized game and fish are known for their incredible jumps and high speed. They can be displayed in a surprising variety of brown and gray subjects purple and silver, too. Sailfish can change their colors change almost instantaneously controlled by the nervous system. The yacht can quickly turn his body blue with yellow stripes when excited, confusing its prey and making capture easier, while signaling its intention to sail colleague Sailfish are two species of fish in the genus Istiophorus living in warmer sections of all the oceans of the world.

Queen Angelfish

 

The Life of Animals | Queen Angelfish | The color adult queen angelfish overall body color can be blue to blue-green with yellow wheels described in its scales. Queen Angelfish is also known to have blue markings around each gill cover. Young people have dark blue bodies with yellow lips, gills and tail and vertical bars ranging in color from blue to white. The colors of young fish to help them integrate into the reef. Queen Angelfish are about three and a half kilos.


The queen angelfish feeds primarily on sponges, but also feeds on jellyfish, tunicates and corals and plankton and algae. Young people serve as "cleaners" and feed on the parasites of larger fish at cleaning stations. Despite having in home aquariums, aquarium made for the queen angelfish diet of meaty foods and algae queen angels inhabit the reef base and are often located near the Florida Keys and Florida in particular, the Bahamas and the Gulf of Mexico.


Pairs reproduce by rising water, the wombs. Freely anywhere from 25 to 75 thousand eggs each night and up to 10 million eggs per reproductive cycle Eggs are transparent, dynamic and pelagic, floating in the water column. The size of the yolk sac is absorbed after 48 hours, during which the larvae develop normal characteristics of free swimming fish. Larvae are in the water column and feed plankton. The queen angelfish harass other fish without discrimination, in particular, the new additions to the aquarium.

Muskox

 

The Life of Animals | Muskox | Both sexes have long curved horns. Average adult weighs 285 kg (600 lb), and the range of 180-410 kg (400-900 lb). The thick and large head often suggests a larger animal musk oxen and really, bison, musk ox, which is regularly compared, can be up to twice as much. Rare 'white' musk oxen were found in the Queen Maud Gulf Bird Sanctuary. Musk oxen are sometimes domesticated for wool, meat and milk. Qiviut wool is valued for its softness, length and insulation value. Musk oxen are native to Arctic regions of Canada, Greenland and the United States. The species was introduced from Iceland Banks in northern Europe, including Sweden. The world population is estimated from 80,000 to 125,000, with an estimated 68,788 living on Banks Iceland. Muskox was successfully introduced in the Taimyr Peninsula in 1975 again.


Musk oxen ate grass pastures arctic woody plants, lichens and mosses. Muskoxen have a high threshold of fat reserves before design, reflecting their conservative breeding strategies. Dig winter camp in the snow surface to reduce total energy costs in the snow to reach food. Musk oxen live in herds that number 12-24 and 8-20 in winter and summer. Muskox have both male and female age hierarchies bills with oxen dominant mature minors. Dominant cattle guard, better access to resources and move subordinates tufts in winter. Muskox bulls assert their dominance in many ways. Shout Bulls swung his head and paws the ground. Tori dominant sometimes treat subordinate bulls like cows. A dominant male accidentally throws one of his subordinates with his foreleg, which are cows during mating.


Some organizations subordinate bull can change the charge state of a dominant male. Coupling (or "rutting") season begins muskox late June or early July. Fighting bulls rub first pre-orbital glands against their legs crying out loud, and then shows the horns of bulls and walk upwards of 20, lowered his head and charged into each other and continue to do so until that when a bull goes. But older people and bulls leave the herd form bachelor groups or become loners. Tori prevent dominant cows from their harems. Herds reassemble when the summer ends. Herds move more frequently when the cows get enough food to feed their children. Cows have a gestation period of 8-9 months with the birth occurring from April to June, cows do not give birth every year. At birth remain the cows in the herd protection. Then begins a calf occasionally eat the vegetation and nurses. Cows and their calves communicate bray.


Musk oxen have characteristic defensive behavior when the herd is threatened, the bulls and the cows are outwardly to form a stationary or semi-circle around the calves. The bulls are usually flock to the first line of defense against predators and cows and young people around. Bulls determine the defensive formation during rutting while the cows decide the rest of the year, Historically, this species has declined due to hunting, but population recovery took place after the implementation of the legislation on hunting. Most populations are in the National Park, where they appear to be protected against hunting muskox in four protected areas of Greenland, found with the indigenous peoples in northern Greenland National Park and three introduced populations in reserves Arnangarnup Qoorua Kangerlussuaq natural and and Manii

The Life of Animals | Two Toed Sloth | As its name implies, have only two toes on their front paws, although, like other sloths have three toes on the hind legs. They are also three-toed sloths. The mother gives birth to a young, while hanging upside down. Two-toed sloths spend most of their lives upside down in the trees. She can not walk, so they prefer to hand to hand, which is extremely slow in one.

Rhesus Macaque

 

The Life of Animals | Rhesus Macaque | The rhesus macaque is brown or gray and has a pink face, which is hairless. Its tail is of medium length and average between 20.7 and 22.9 cm (8.1 to 9.0 inches). Adult males measure about 53 cm (21 inches) on average and weigh about 7.7 kg (17 lbs). The females are smaller, with an average of 47 cm (19 inches) long and 5.3 kg (12 lbs). Rhesus macaques have an average of 50 vertebrae. The rhesus macaque has 32 teeth with a dental formula 2.1.2.3/2.1.2.3 bilophodont molars. The lower molars also have four cusps: metaconid, protoconid, hypoconid and entoconid. Rhesus monkeys are native to northern India, Bangladesh, Pakistan, Nepal, Burma, Thailand, Afghanistan, Vietnam, southern China and neighboring regions. They have the widest geographic distribution of a non-human primate, occupying a wide range of altitudes throughout Central, South and South-East Asia.


Broadening the range of rhesus macaque a natural process in some regions and a direct consequence of the introduction by humans in other regions has serious implications for the declining populations of endemic and bonnet macaques in southern India Rhesus monkeys are diurnal and arboreal and terrestrial time. During the monsoon season, which derive much of their water from fruits ripe and juicy. Macaques who live far from water sources lick the dew from the leaves and drink the rain water accumulated in tree holes. Drink water when they feed and congregate around streams and rivers. Rhesus monkeys are specialized pockets like the cheeks, which allows them to accumulate temporarily foods.


Rhesus macaques interact with a variety of vocalizations and body postures and facial expressive gestures. Perhaps the most common expression of the face makes Java is the "silent bared teeth" face. During the movements, macaques will "tuba" and "grunts". When foods are rarely high quality macaques makes "chirping", "harmonic arches" or "correction." When at risk, macaques emits a high-pitched sound which he called "sour bark." "Oops", "cry", "twitter", "pants-threats," "growls" and "bark" are used in aggressive interactions. Babies "gecker" to attract the attention of his mother. Adult male macaques seek to maximize their reproductive success by taking wife couples with women, both inside and outside of the breeding season. The females prefer to mate with males that increase the survival of their offspring. So a man marries provides resources for girls and protects them from predators.


Male rhesus macaques were observed to fight for access to sexually receptive females, but suffer more injuries during the mating season. Male macaques generally play no part in rearing the young, but they have peaceful relations with their children, couples wife. Mothers with one or more immature girls, and their children are in contact with the younger children of those who have immature older girls and mothers can pass the responsibility of raising their daughters. Children farther from the center of the most vulnerable groups outside infanticide. Some mothers abuse their children, which is supposed to be the result of controlling parenting styles.
