Recommended: Environmental adaptation of wolves
Although Timber and Arctic Wolves originate in two different places, they still have similarities and differences. Arctic Wolves and Timber Wolves have been around for about 110 years. They have adapted in different ways to their environments over the many decades. Arctic Wolves live in the Canadian Arctic, and northern parts of Greenland. Timber Wolves live in mountains, temperate forests, and Grasslands. Timber Wolves are the largest wolves in the canine family. They weigh 75- 125 lbs, and some males grow up to be 175 lbs, but this isn’t often. Arctic wolves are smaller than timber wolves by 3-6 feet. They are bulkier than timber wolves, and are usually over 100 lbs. Male Arctic Wolves are more often to be 175 lbs than Timber Wolves. Arctic wolves also have smaller ears, which helps maintain body heat. Timber Wolves live six through eight years, and are in packs of two …show more content…
For instance, the Timber Wolves breed from January to April, while the Arctic wolves breed from May to June. That is about two months shorter than the timber wolves! Usually the alpha male and female Timber Wolves breed together, and they usually have around six in a litter, but can have a range from one to eleven. The female Arctic Wolves have their pups from two to three years, which is almost a month later than any other wolf species! Although there are many differences in these two wolf specie’s life cycle, there are still similarities. Like humans, Timber and Arctic wolves do not leave their pups! The parents provide meat and meda for food, along with shelter. When these pups are older they can either stay in their original pack or find a different pack. The Timber and Arctic Wolves lifespan is an average of seven years, but usually five to six because of lack of prey. When the wolves are pregnant, they live underground to keep safe from any other species out in the open. This is good for the mother and the wolf
In this research paper, I will address the changes that occurred within the ecosystem of Yellowstone National Park since the reintroduction of the grey wolves. The paper will consist of four sections; the first section will include the history behind the extirpation and subsequent reintroduction of the gray wolf in Northern America. The second section will explore the political controversy that surrounds the reintroduction of the gray wolf in Yellowstone. The third section will contain discuss the gray wolf and its impact on the ecosystem of Yellowstone. I will conclude my essay by explaining how the gray wolves act as climate change buffers in Yellowstone amidst global warming.
Gray Wolf Optimization Gray wolf optimization is presented in the following subsections based on the work in [13]. 1) Inspiration: Grey wolves are considered as apex predators, meaning that they are at the top of the food chain. Grey wolves mostly prefer to live in a pack. The group size is 512 on average. They have a very strict social dominant hierarchy.
Many hundreds of years ago wolves roamed the entire North American continent with no barriers and very few predators. As settlers moved into the United States, wolves became more and more scarce in the wild of America. As the wilderness areas of the United States declined, so did the population of the wolf, until there were only a few spots in the wild where wolves could still be found.
Hypotheses of the Effects of Wolf Predation Abstract: This paper discusses four hypotheses to explain the effects of wolf predation on prey populations of large ungulates. The four proposed hypotheses examined are the predation limiting hypothesis, the predation regulating hypothesis, the predator pit hypothesis, and the stable limit cycle hypothesis. There is much research literature that discusses how these hypotheses can be used to interpret various data sets obtained from field studies. It was concluded that the predation limiting hypothesis fit most study cases, but that more research is necessary to account for multiple predator - multiple prey relationships. The effects of predation can have an enormous impact on the ecological organization and structure of communities.
One of the biggest reasons for the reintroduction of wolves back into Yellowstone was that they had originally roamed from Yellowstone all the way down to Mexico. While a lot of people were in favor of the reintroduction of the wolves, there were many who were against it. The main people who were against the reintroduction of the wolves back into the park were the ranchers who made a living in the areas surrounding the park.
Not many people know about the arctic wolf, it is the snowy white version of a wolf. They have a really big appite when it comes to eating. They most only eat one meal a day and eat up to 20 pounds in that one meal. They are mostly carnivores; they mainly eat big animals like the caribou and the musk ox so they can feed themselves and the whole pack (Arctic/Antarctic: The Arctic Wolf). People eat up to three meals a day, but wolves can go up to days with out eating a single thing (Arctic/Antarctic: The Arctic Wolf). When wolves are hunting they have to be able to have a plan to catch their food. Wolves would get all the pack members that are hunting to surround the animal, and pounces on them. One bit to the neck and the animal would be dead. When they are eating they will eat everything, like the meat, shin, fur and bone (Arctic/Antarctic: The Arctic Wolf). Also Arctic wolves can live up to 20 years in captivity, while they can only live 7- 15 years in the wild (Arctic/Antarctic: The Arctic Wolf). Arctic wolves are one of the most prettiest and unique types of wolf. When Arctic wolves are pups t...
This report is all about the gray wolf. Its scientific name is Canis Lupis. Canis is the Latin word for dog. The genus also includes jackals and coyotes. Lupis is the Latin word for wolf. Gray wolves look similar to German shepherds, but the wolf has longer legs and bigger feet. The color of a gray wolf can range from black to white, but shades of gray are the most common. A unique feature about gray wolves is that the farther north you find them, the larger they are. Males can range from (nose-to-tail) five to six and a half feet and females range from four and a half to six feet. The normal life span of a wolf is about thirteen years, but most wolves don’t live past ten years for numerous reasons. Examples include disease, hunters, etc. The wolves that live in Arctic climates have very thick coats of fur that keeps them warm. Wolves, like all canines, have 42 teeth. Their “fangs”, or canine teeth, are used to grab prey and like a hook. These teeth can be as long as two and a half inches.
Sometimes they even hunt moose. Their sense of smell is superior. Wolves hunt in packs all male to be exact. Wolf packs are mostly led by the parents of the wolves and some other wolves with the parent wolf to join their pack for hunting and killing their prey. The Gray Wolf can also run as fast as 31 - 37 MPH which makes them really good hunters. And they have been seen viciously attacking people. Unlike some animals wolves don’t hibernate so they have to hunt all year. Wolves also tend to mate in the early spring as well. Then before you know it the female wolf has babies some time during the winter, and their babies also have to eat.
According to eol.org Kit Foxes are mainly monogamous, which means that they usually mate for life. The specific mating patterns that occur within the Kit Foxes usually occurs from mid December to January, with litters being able to hold up to one to seven pups at a time. New born’s are weaned and nurtured up until about four weeks and usually become independent at around five to six months. It is not uncommon for young females to delay and completely skip their independence part of their lives to stay back in their homes in order to help raise the next litter of pups that are going to come. Individual Kit Foxes have been known to live up to seven years in the wild on their own. Kit Foxes are the types of animals that are most active in the night, but have a tendency to have crepuscular behavior. Upon finding a mate it is not uncommon for them to share the same dens throughout their year of life together. Each pair of foxes
Canis Lupus, the Latin term for the “North American Wolf”. A meat eating mammal with the capability of weighing up to 180 pounds and reaching a height of sixty-three inches, the wolf is easily the largest member of the canine family. Over 500,000 wolves once lived in harmony, roaming the Northern Americas alongside the Native American tribes and the rest of the ecosystem. Wolves live in packs, a pack essentially being a family. While the average size of a pack is six to ten, the largest confirmed pack recorded in North America can be found in Yellowstone National Park where the “Druid Pack” numbers thirty-seven strong and counting. There have been alleged reports of a pack that attacked a small Russian town killing thirty horses in just four days. This pack numbered up to almost 400 members. Animal experts remain suspicious due to the fact that this number is almost fifteen times the size of an average sized pack. Wolves heavily rely on their pack. Every member of the pack has a specific job that benefits the pack, without the pack, death would be almost imminent. The pack is set up as a hierarchy, with an alpha male and an alpha female. The alphas get the best of everything, the best part of the kill, the best sleeping spot, and the breeding rights. When hunting, one member will scout ahead and will determine the weakest member of the herd. Once determined, the rest of the pack will chase the animal down and either takes it down on the run or chase it until it tires out. Unlike many predators in the animal kingdom, wolves eat their prey alive. While wolves are known for their spine tingling howls, the howl is not the only way they communicate. “Wolf Language” so to speak, consists of many grunts, snarls, growls, yips, and whines....
The most likely scenario for wolves beginning to coexist with humans is that a human hunting party came across a very young wolf cub and decided to take it with them. The wolf cub would have been very puppy-like at an early age. The reason that humans would ever take a wolf cub is because the cub would be seen as a valuable resource to humans back then. The wolf cub would become a sort of tool for humans since it is a better tracker, has keener senses, and is faster then humans. The hunters would have figured they and wolves were both hunters and hunted in packs. The humans would share their food with the cub and protect it from being hunted by outside animals, but they would also use the cub to keep them alive by having it track down prey for food. Also, they would probably watch to see if the cub sensed danger in the nearby area so then the hunters could avoid it, too.
Wolves had live throughout parts of the world for thousands of years before humans just kept rising in population and minimizing the wolves’ population through the expansion of their territories for farm agriculture and industrialization. It is only in the United States where humans completely annihilated wolves; they did this by hunting the wolves down until the last wolf was killed in 1926. However, in 1995, 14 wolves were caught from Canada and release into Yellowstone National Park. This makes it almost 70 years since the wolves have been reintroduced back into Yellowstone National Park (17 July 2009)
Studies show that wolves play a significant role in maintaining healthy ecosystems, and could even help stave off some of the effects of climate change. They help keep large animal herd populations in check, which can benefit numerous other plan...
Many fairy tales in literature convey hidden messages and meanings that can be found in almost every aspect of life. These subliminal messages are prevalent in the short story, “The Company of Wolves”, through the theme of gender inequality. In “The Company of Wolves”, Angela Carter displays the issue of gender through a feminist light in the plot and through symbolism, as she consistently symbolizes the woman and the wolf creature as archetypal ideologies of their own gender.
MATING: Siberian tigers mate in winter months and following a 3-5 month gestation period, the female produces 3-4 cubs. Cubs weigh just over 2 pounds each and are born blind. The small litter of cubs stay close to their mother for the first 8 weeks of life. By 18 months, the young are capable of hunting on their own. Young stay with their mother for 2 years, at which time they leave the pact and travel solo. The life span of the Siberian tiger is 15 years in the wild, and significantly longer in captivity.
