Biologie des WolfesAm Wolfsforschungszentrum erkunden wir die Gemeinsamkeiten zwischen Wolf, Hund und Mensch. Unsere Wölfe und Hunde werden von Wissenschaftlern. Der Wolf ist rezent das größte Raubtier aus der Familie der Hunde. Wölfe leben meist in Familienverbänden, fachsprachlich Rudel genannt. Hauptbeute sind in den meisten Regionen mittelgroße bis große Huftiere. Von allen Säugetieren hatte der Wolf (Canis lupus) ursprünglich das weltweit größte Verbreitungsgebiet. Er besiedelte fast die gesamte Nordhemisphäre bis zum.

All of a pack's adults help to care for young pups by bringing them food and watching them while others hunt. Gray wolf. Wolves With their piercing looks and spine-tingling howls, wolves inspire both adoration and controversy around the world.
Find out how many wolf species exist, the characteristics that make each wolf's howl unique, and how the wolf population in the continental United States nearly became extinct.
Photographs by Joel Sartore. WATCH: Photographing the Wild Wolves of Yellowstone Hear photographer Ronan Donovan describe the challenge of documenting one of Yellowstone's most elusive and iconic species.
Continue Reading. They mate in late winter. The female has a gestation period of nine weeks and gives birth to a litter consisting of one to 11 pups.
When the pups are born, they are cared for by all of the adult wolves in the pack. Young pups start off drinking milk from their mother, but around five to 10 weeks they will start eating food regurgitated from adult pack members.
At six months, wolf pups become hunters, and at 2 years old they are considered adults. On average, a wolf will live four to eight years in the wild.

Though wolves once roamed far and wide, they are very scarce today. The International Union for Conservation of Nature and Natural Resources IUCN lists red wolves as critically endangered.
According to the National Parks Conservation Association, there are 20 to 80 red wolves currently living in the wild. The Ethiopian wolf is also listed as endangered by the IUCN.
The Eastern wolf is threatened and is protected in Canada. Packs of wolves don't like to stay in one place. They are known to travel as far as 12 miles 20 kilometers per day.
Wolves have friends. Wolves howl to communicate with other members of the pack. If other adult wolf members of the pack mate, the alpha female wolf will be aggressive towards the other female wolf and usually the alpha male wolf will chase the other adult male wolf out of the pack.
It is common for one litter of pups to be born to one pack of wolves. It is rare for two litters to occur unless the alpha male has mated with another subordinate female.
This is usually when the alpha female wolf gets aggressive. The alpha female will try to prevent this by aggressively dominating other females and physically separating them from the alpha male wolf during the mating season.
When breeding season arrives breeding wolves begin to get more affectionate with each other. This occurs in anticipation of the females ovulation cycle.
Pheromones in the females urine and the swelling of her vulva, tell the male she is ready to mate.
During the first 5 days of estrus, the female will shed a lining of her uterus and will be unreceptive to the male. Following this, she will begin ovulation and mating will occur.
During the period of mating, the two wolves become physically inseparable for anywhere between 10 and 30 minutes, during which time the male wolf will ejaculate multiple times.
The mating ordeal is repeated many times throughout the females brief ovulation period, which occurs once per year per female unlike female dogs, with whom estrus usually occurs twice per year.
It is believed that both male and female wolves can continue to breed in this manner until at least 10 years of age. Once the alpha pair have mated, the gestation period lasts from 60 — 63 days.
Wolf pups are born blind, deaf and completely dependant on their mother. There can be between 1 — 14 pups in one litter, with the average number being 4 — 6 pups.
For the first 8 weeks, the pups will stay inside the den in which they were born. The den is usually on high ground, near and open water source.
During this time, the pups will grow and become more independent. The wolf pups will begin to explore the area just outside the den, gradually roaming up to a mile away from it.
At 4 weeks old, the pups milk teeth have appeared and they begin to eat regurgitated food. At 6 weeks old they are weaned. During the first few weeks the pups are developing, the alpha mother will stay with them alone.
Eventually, the rest of the pack will join in with the rearing of the pups in some way or other. The wolf pups stand a better chance of surviving when more wolves contribute to their care, such as bringing them food and guarding them from danger.
At 2 months old, the wolf pups will be moved to a safe place which they will reside in while some of the adult wolves go hunting.
One or two adult wolves will of course stay behind to watch over the pups and keep them safe. After a few more weeks of development and growing, the wolf pups are sometimes allowed to join in on the hunts.
The wolf pups are only allowed as observers, however, until they are about 8 months old, by which time they are large enough to actively participate.
The wolf pups receive first rights on anything killed regardless of their low rank within the pack. Letting the wolf pups fight for the right to eat, results in a secondary ranking being formed among them and lets them practice the dominance and submission rituals that will be essential to their future survival in pack life.
Wolves typically reach sexual maturity when they are around 2 — 3 years old. At this time, a wolf may feel the need to disperse from its pack, find a mate and start a pack of its own in its own territory.
Wolves were mistakenly viewed as a pest species and almost exterminated. We are more enlightened today, although this opinion still remains among farmers.
Through the efforts of ecologically-minded people and with the Endangered Species Act funding, the wolf is being reintroduced in parts of North America.
With an increasing number of animals throughout the world either in a critically endangered situation, becoming endangered or a threatened species, wolves are no exception.
Many projects are being carried out to reintroduce many wolf species such as the USFWS in North America and the International Wolf Centre.
Learn more about wolves by looking at Wolf Web sites and reading more about them in books. You will find lots of information about them on the internet and on personal web pages.
Tell your friends and other people what you know about wolves, and how important they are to this world and how important it is to save a place for them in nature.
The gray, or timber, wolf Canis lupus is the better known. It is the largest nondomestic member of the dog family Canidae and inhabits vast areas of the Northern Hemisphere.
The Ethiopian, or Abyssinian, wolf C. Pervasive in mythology, folklore, and language, the gray wolf has had an impact on the human imagination and has been the victim of levels of misunderstanding that few animals have shared.
It lived in every type of habitat except tropical forests and the most arid deserts, and it was the premier hunter of the large hoofed mammals. Several subspecies occur throughout North America, Eurasia, and Africa; however, classifications disagree on the number of wolf subspecies.
Wolves were domesticated several thousand years ago, and selective breeding produced dogs. The wolf is built for travel.
Its long legs, large feet, and deep but narrow chest suit it well for life on the move. Keen senses, large canine teeth, powerful jaws, and the ability to pursue prey at 60 km 37 miles per hour equip the wolf well for a predatory way of life.
A typical northern male may be about 2 metres 6. Standing 76 cm 30 inches tall at the shoulder, it weighs about 45 kg pounds , but weight ranges from 14 to 65 kg 31 to pounds , depending on the geographic area.
Females average about 20 percent smaller than males. The largest wolves are found in west-central Canada, Alaska, and across northern Asia.
The smallest tend to be near the southern end of their distribution the Middle East , Arabia, and India. Fur on the upper body, though usually gray, may be brown, reddish, black, or whitish, while the underparts and legs are usually yellow-white.
Light-coloured wolves are common in Arctic regions. Early human societies that hunted for survival admired the wolf and tried to imitate its habits, but in recent centuries the wolf has been widely viewed as an evil creature, a danger to humans especially in Eurasia , a competitor for big game animals, and a threat to livestock.
Depredation of livestock was the primary justification for eradicating the wolf from virtually all of the United States, Mexico, and most of Europe.
Wolves in the United States were killed by every method imaginable in the 19th and early 20th centuries, and by they remained only in the northeastern corner of Minnesota.
In the late 20th century, greater tolerance, legal protection, and other factors allowed their range to expand in portions of North America and Europe.
Wolves are probably more popular now than at any other time in recorded history. In wolves from Canada were reintroduced to Yellowstone National Park and Idaho, and captive-reared Mexican wolves a subspecies were released to their former range in eastern Arizona beginning in At the beginning of the 21st century, an estimated 65,—78, wolves inhabited North America.
