Endangered species of the US:
Western region: Bakersfield Cactus, often Trealese’s Beavertail prickley pear (Ranis pretiosa)
The Bakersfield cactus is now listed (1990) as an endangered species due to habitat loss from open range to citrus groves, residential development and petroleum production. Other human effects are off-road activity, trash dumping and gravel mining. Competition from other grasses as well (exotics) is affecting this prickly pear. There is a recovery plan in place (1998) and we can wait and see what will happen with this pain-inducing species. Southeast region: The Ozark Hellbender:
The clear fast moving waters of the Ozarks can be lots of fun from fishing to kayaking. The story of the Ozark hellbender’s decline is an all too familiar one just like many of the other endangered species– increased siltation, water quality degradation, and increased human interference to their habitat. To add insult to injury, a highly infectious chytrid fungus is proving fatal to an ever-increasing number of amphibians throughout the world. Over 75 percent of hellbender deaths that occurred in the St. Louis Zoo’s captive population from March 2006 through April 2007 were due to this disease. This prompted the testing of Missouri’s wild Ozark hellbenders, and they found that 100% of the population was infected.

Global endangered species:
Panamanian Golden frog ((Atelopus zeteki),
Considered lucky by the Panamanians, A. zeteki was first listed under the ESA in 1976. It too is undergoing a rapid decline through human interventions. Factors affecting A. zeteki include illegal collecting for the pet trade as well as legal collecting for hotels and Zoos. Deforestations as well as stream sedimentation from logging and local farming. And then you add insult to injury again. The chytrid fungal problem that affects the hellbenders in the Ozarks. This pathogenic fungus is what may have caused the golden toad (Bufo periglene)to go extinct and A. zeteki may possibly become extinct at this time.
Rosy Periwinkle: the miracle cure (Catharanthuss roseus)
Considered endangered in the wild rain forests of madagascar, modern day researchers found that the Madagascar healers used C. roseus to cure diabetes and other ailments. This led them to find the chemical alkaloids that are active. Vinblastine and Vincristine are two of the most valuable. Vinblastine has raised the cure rate of Cchilhood Leukemia from 10 to 95% and Vinblasitne is used to treat Hodgkins Disease. Fighting over the rights to the drug companies money (even to the extant of being called pirates) is ongoing to this day. This plant is cultured successfully worldwide in subtropical climes both for ornamental purposes and medicinal purposes.

Wolves

...Wolves My project is going to be on wolves. Wolves are fierce and beautiful creatures. With their strong jaws and sharp teeth they are deadly hunters, but wolves can be gentle and playful too. Most packs contain between 5-8 wolves. Small packs may have about 2 members. Large packs can hold up to 30 wolves. Wolves have many different ways of communicating with each other. They can make a wide range of noises, including snarls, whines, whimpers, squeaks, and barks. Wolves in a pack are mostly friendly and affectionate with one another. When two pack members meets, they whine, wag their tails, and lick one another’s fur. Wolves are carnivores, they mainly eat meat. They prefer to hunt and eat large animals such as moose, muskoxen, elk, and caribou. These creatures are powerful, armed with sharp hooves, and fierce horns or antlers. They can only be hunted by wolves in a pack. Other wild dogs like cats, bears, raccoons, hyenas, and seals are also carnivores. Like members of the dog family, wolves breed only once a year. Mating takes place in late winter. The young develop inside the mother for 63 days until birth. Two weeks after they are born the cubs are bigger and stronger. They can know hear and they eyes are open so they can see. They clamber over one another to reach the warmest places under their mother’s body. By the age of three weeks they are able to stand and wobble to the den entrance; they sniff the air and look outside the world. ...

Wolves Research Paper

...Wolves Wolves are very interesting animals. Wolves are from the kingdom animalia, phylum chordata, class mammalia, order carnivore, family cavesnidae, genus canis, and species lupus. They come in many subspecies and inhabit a wide variety of habitats in North America and Eurasia including the arctic, tundra, temperate zones, desserts, forests, taiga, and sometimes even urban areas. (www.en.wikipedia.org/wiki/Wolves). Wolves have survived through the ice age. An ancient form of primitive wolf may have originated seven hundred fifty thousand years ago in the eastern part of North America which are thought to be the ancestors of the Eastern Wolf and Red Wolf. Wolves have been in folklore, myths, and cave paintings throughout history. In some cultures wolves were respected and revered, but in other cultures they were feared or looked down upon. Their behaviors have frequently been misunderstood by people. The wolf was once the most widely distributed mammal in the world. Their decline in population and reduction in territory is due to people destroying their habitats and killing them. There were once about fifty subspecies recognized, but the list can be condensed to about thirteen-fifteen general subspecies due to DNA testing, anatomy, distribution, and migration. In 2005, thirty-seven subspecies existed including the dingo and the dog. Some subspecies are extinct or endangered. Some subspecies have been saved by conservation efforts and are being...

Endangered: Understanding Wolves

...Endangered: Understanding Wolves Roxanne Green Devry University ENGL135 Cynthia Pengilly April 10, 2011 Abstract Understanding the wolf and their ways of life is the key to saving these animals from extinction. Throughout time people have killed wolves out of fear, because they want their fur, or because they have lost livestock to a wolf. Fear comes from not knowing, not understanding the wolf and their life. Loss of livestock happens because people take over the wolves land and territory, killing off the wolf’s prey and introducing livestock. By education people can become familiar with the ways of the wolf and help this very important animal from becoming extinct. Endangered: Understanding Wolves The beauty of a wolf is breath taking; they are fascinating creatures that will set fear in most people. They have been the center of attention in myths, legends, and folklores creating a relationship that is not only ancient but complex between humans and the wolf. Wolves are social predators that live in families and they develop packing orders. The wolf is the largest member of the canine family. At one time they lived in large areas in North American, Europe, and Asia. The most common threat and source of death for the wolf has been people. Over time they have been hunted so much that they are now near extinction. Wolves are feared animals; they are misunderstood, people want their fur, and complaints of livestock being killed by wolves are leading these animals to...

John lived with the indians in their forts for many months. John went back to his fort and when he got there he saw that American soldiers had set up there and attacked John when he arrived. They interrogated him and were going to put him to death. Just in time the indians saved John and he safely got home. John and his wife left and as the movie was ending they closed with the American soldiers finding the indian troops and were said to have destroyed all their forts and wiped out the indian population.

To start off the American soldiers did murder lots of indians but they didn’t completely wipe out their population, there are still indians alive today. Also when John found the women she just became widowed and it is a ritual...

Analysis and Interpretation of the Company of Wolves

...Analysis and interpretation of “The Company of Wolves” The Company of Wolves is an interesting rewriting of LRRH* and a female author’s slightly feministic interpretation of an old classic. You can see that the story is a rewriting of “LRRH” because there are a lot of similarities. For example in both stories we have a little girl walking through a forest to give her grandmother a basket of dainties . Besides that we also have the classic sentences: “What big eyes you have”, “What big arms you have” and “What big teeth you have”. The story is a rewriting so of course there are also differences like that we don’t have a heroic hunter who comes and saves the grandmother and the girl and the wolf’s genitals is described in a way so the story might not be the best bedside reading. The girl is about twelve years old (p. 22: “she has just started her woman’s bleeding”), has flaxen hair and wears a red shawl. She is a latecomer and has been so indulged that she does not know about the dangerous world she lives in (p. 22: “in this savage country”, p. 23: “she is afraid of nothing”). She is described as very innocent: Pretty, pale, fair hair like lint and virginity (p. 22). The hunter part of the wolf is described as: “a handsome one” and “a fine fellow” (p. 23). Besides that the author describes him as gallant since he offers her to carry her basket. He is a real gentleman. The wolf part of the wolf is on the other hand described as: “a beast of...

Who Is Michael Blake's Dances With Wolves?

...Dances with Wolves by Michael Blake was published in 1986 after many years of rejection after rejection. This two-hundred-eighty-five page historical fiction novel tells the beautiful and awe-inspiring tale of young Lieutenant John Dunbar and his love for the vast open prairies of South Dakota. But, what is perhaps even more wonderful is the people who inhabited the land long before white men ever thought to settle it. This extraordinary tale shows the prejudices of whites against Indians and one man’s attempt to bridge that gap and save the land and people he has grown to love more than life itself. Dances with Wolves takes place in the year 1863 at the tail-end of the Civil War when morale runs lower than resources. Lieutenant John Dunbar is sent with supplies to a desolate Fort Sedgewick. Upon his arrival the fort has been abandoned, its men gone back to the East Coast. Ever vigilant to his duties, Dunbar holds the fort, hoping that they will return and reinforcements arrive. All is for naught, his presence at the fort is not known by anyone, save himself. As time passes he soon finds himself in the company of an older wolf, Two-Socks. The two form a strange friendship and Dunbar finds peace and beauty on the prairie he has never felt before....

...The Wolves By Paisley Rekdal It was the week of asking. Asking to watch her eat. Asking if she understood the doctors’ questions. Asking her to explain the difference between wanting to die right now, and dying later. The tumor making certain answers unquestionable. I watched her point to the incense dish from which someone swept all the ashes up. Asking if she recognized us. Because that is what the living want: thinking it is a sign we have been loved. But the answer was a summer drive, a mountain, piles of leaves beneath which a wolf slept, suckling her cubs. Some deaths are good and it makes them hard to grieve. She was, at times, in great pain. We wanted her to die, too. That was important. But first we wanted her to remember. From the bed, a finger pressed into a pile of leaves. Gray haunch, unmovable ashes. I didn’t want to disturb their tableau, she told us. And drifted off. And we did not know the meaning behind this. The wolves must have looked so comfortable to her: wordless and in this wordlessness perfect. Did she want to go there, too. I could point to the image and say, my father must be in there, my uncle. Or: the wolf is you, you are still the mother, as if necessary to name that self at the end of its world. An animal cry, memory. That was our selfishness. As death was hers. She insisted upon it. And why not. It was good for me to get a chance to know you, she said, who had known me my entire...

The Big Bad Wolf

Such myths and legends have portrayed the wolf as a threat to human existence. Feared as cold-blooded killers, they were hated and persecuted. Wolves were not merely shot and killed; they were tortured as well. In what was believed to be a battle between good and evil, wolves were poisoned, drawn and quartered, doused with gasoline and set on fire, and, in some cases, left with their mouths wired shut to starve (Begley 53). Convinced that they were a problem to be solved, U.S. citizens gradually eradicated gray wolves from the lower 48 states over a period of 25 years. Today many people are convinced that the elimination of the gray wolf was not only an error, but also a detriment to the quality of life in this country. There has been a public outcry to rectify the situation created by the ignorance of our ancestors. However, in seeking to address a situation created by the human compulsion to control nature, it is crucial to discern how much human interference is necessary.
