Recommended: Value of Species as Umbrella Species and Keystones
Every pack of red wolves has its own home range which they hunt in and defend aggressively from other canids. If necessary, red wolves will fight other wolves to defend themselves and their territory (“Red Wolf” nd). Red Wolves are generally shy and secretive and hunt alone or in their packs. They are also nocturnal. Red wolves communicate in a variety of forms including scent marking, vocal sounds like howling, facial expression, and body postures (“Red Wolf” 2017). From the 63 red wolves released in the late 80s/early 90s after they were bred in captivity, the population reached around 120 wolves in 2012. Since then, however, it has declined, and in the 2015, only 50-75 wolves remained (“Causes of mortality in wild red wolves (Canis rufus) 2012–2015”). The red wolf has massive ecological, economic, and cultural value. According to the U.S. Fish and Wildlife Service, it is both an umbrella and a keystone species. As an umbrella species, efforts to conserve the red wolf will also benefit other plants and animals within its habitat. Moreover, the red wolf is an …show more content…
Thirty years later then we can look at their progression and determine if the action was worth it and if further action to protect the species would also be worth the costs. There is an excellent case to be made for the conservation of the species since it acts as both a keystone and umbrella species for its environment. As previously stated, the red wolf provides numerous ecological, economic, and cultural values. On the other hand, despite the millions of dollars spent and the extensive actions done by the U.S. Fish & Wildlife Service over the past forty years, the species is again in decline and facing extinction, bringing into question if all the money and effort spent is worth it or if the species can even be
After reading "scared to death" and "wolf family values" I think the second article gave better reasoning behind why we should protect the wolf population. Both articles talk of the wolves return to Yellowstone national park, but the first essay "scared to death" by Ed Yong focuses on the wolves effect on the elk population. The second essay "wolf family values" by Sharon Levy focuses mainly on the wolves and their population and changes of their behavior because of hunting and trying to manage the population. it also focuses on the effects they have on the environment in general.
The gray wolf, Canis lupus, on Isle Royal is a small ever fluctuating population. On the endangered species list since 1978, the gray wolf has recently been taken off the endangere...
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.
National Parks are the cornerstone of every country because it preserves the rich cultural and natural resources of a nation, such as Yellowstone in the United States of America. Yellowstone National Park is the World’s First National Park which brings millions of attraction each year, it is larger than Rhode Island and Delaware combine and have over a thousand species of plants and animal (Yellowstone Media). However, a very important type of species has been missing in Yellowstone National Park for a very long time. Wolves, which got reintroduce back into Yellowstone National Park, should stay there because without them the ecosystem would be out of balance.
Over the past several years, the gray wolf, native to the Wisconsin area, has been listed federally as an endangered species due to the graphic and horrific treatment they had received during the industrialization periods of America, when they were frowned upon and hated because they are predatory creatures and did, on occasion, attack livestock and pets. Because the government was encouraging the hunting, including bounties for the animals, the wolves were hunted to near extinction. However, now Wisconsin faces a new problem. With the reintroduction of the wolves to the state, and their continued endangered status federally, the population has increased well beyond expectations, reaching what could be considered a problematic state. A regulated hunt and a population control procedure has become necessary in Wisconsin to protect state's economic endeavors of game, wildlife, and agriculture, and also the wolves themselves, to keep them from overpopulating and facing starvation and lack of land.
The history behind the extirpation of the grey wolf in the United States dates back to the very first European settlers that colonized eastern North America in the late 16th century. The killing of gray wolves was done primarily out of fear in an attempt to protect livestock, and, in some cases, to protect human life within the colonies. As more settlers expanded West, the practice of killing wolves was considerably increased to protect livestock that included cows, pigs, and chickens. As waves of European settlers expanded westward, they began to deplete the deer, moose, and elk populations. The gray wolves food source continual depletion gave rise to wolf populations actively targeting the settler’s livestock, causing great financial loss. The fiscal loss of livestock became such an issue to wealthy ranchers and settlers that they began to offer cash rewards for wolf pelts. This practice gave birth to a lucrative cottage industry of professional hunters and trappers. As the wolves began to move further West, and into Wyoming, they began to diminish the elk and moose population. To respond to this threat, Congress approved funding in 1914, to eliminate the native gray wolves from
Wolves have always been a symbol of the wild, free in spirit and roamers of the land. These animals are considered majestic and protectors of the wilderness. They have always roamed the western United States, although their population has fluctuated over time. Over the past 10 years wolf reintroduction into Yellowstone National Park has been a controversial topic to those of the United States. As of 1995, wolves have been reintroduced into the park. This has come with some strong opposition and yet has prevailed. The future of the wolf in Yellowstone park is now looking bright, although not certain since there still are those who want them banished again.

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...
Wolves generally live in packs. A typical wolf pack would include a leader male and female wolf (alpha wolves), their pups, and possibly several other non-breeding adult wolves. Packs can vary from 25 square miles to 500 square miles, depending on the availability of prey. Within a pack, only one pair of wolves mate. This pair is known as the “alpha pair.” The female wolf only goes into heat once a year in January or February. If she becomes pregnant, she wil...
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 controversy surrounding the reintroduction of the wolves are many from both sides. Some local farmers are against it because some wolves hunt their animals. However, if the farmers can prove their animal was attacked by a wolf, then the government would reimburse them for the animals value. Another problem is that some taxpayers are against the reintroduction because it cost them money to get the wolves back into the park. Another issue for taxpayers is that they have to pay for the damage the wolves do to the farmer’s animals.
In comparison, wolves were gone from Yellowstone for more than 70 years. While they were gone, the ecosystem continued to function properly. With the gray wolf returning, the ecosystem improved. Yellowstone depends on the gray wolf to hel...
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.
Let me tell you something. In 1970, Gray Wolves used to have a population of 250,000. But now due to mass wolf hunting, the numbers are down to 500. Hello everyone. Today, I’d like to speak on behalf of the Wolf Conservation Center about the importance of wolves, and why they should be protected. Wolves are too often a misunderstood creature, instead of showing fascination, we always fear them, which is the exact opposite of what we should be doing. The society of wolves is just like ours, sorted by ranks, defined by confidence, and full of emotions. We are more like them than we think. Except they are being hunted, and we are not. In many parts of where they range, all types of wolves are being persecuted for killing livestock. As a result, humans have been killing wolves for years, because of us, their numbers are decreasing by thousands.
