“Rabbits and Wolves”
Introduction
I will be conducting a computer simulation called “Rabbits and Wolves”. In this experiment I will be interaction with a simple forest ecosystem model that will simply take into account three organisms: rabbits, wolves, and grass.
As defined by “Environmental Science- 14th Edition”, an ecosystem is “a set of organisms within a defined area or volume that interact with one another and with their environment of nonliving matter and energy.” I will be using the computer simulation to alter the interactions of the organisms in the ecosystem to see what changes occur.
Based on mathematical formulas and probability of certain events occurring, the model predicts the changes in the populations of the three organisms. I will be able to change different variables, such as the starting number of organisms, the reproduction rate, the food consumption rate, the growth rate, and more.
I will be able to analyze the data I gain from this simulation to observe how changes in an ecosystem can alter the organisms that live in the ecosystem.

Objectives
1. To view and interact with a simple scientific computer model.
2. To determine how simple changes in populations of one organism will effect populations of organisms in the same system.
3. To use a computer model to complete objective 2.

Hypothesis
I believe that allowing a greater number of rabbits in the beginning of the simulation will allow the rabbits to out-populate the wolves to a very large degree, so that the rabbit population doesn’t risk extinction in the face of the wolves predation.

Wolves

...settlers and American Indians existed together in harmony with wolves. Many of the wolves’ ways were adopted by pioneers, but later became enemies when the settlers’ livestock was hunted for food. Today, wolves are a symbol of the wilderness, a world in which men and women have long forgotten. They are beautiful, highly intelligent, but sadly very misunderstood creatures. Wolves are a remarkable because of their social structure, physical traits, and communication. Wolves function as a social pack and are established according to a strict hierarchy, with a dominant male and his mate. The leaders of the pack have the greatest amount of social freedom compared to the rest of the pack. In addition, they help resolve any disputes within the pack and have greater control over resources, such as food. Also, the dominant male and female are usually the only animals of the pack to breed. Second in command are the beta wolves and at the lowest position in the pack is the omega. Furthermore, all wolves in the pack assist in raising wolf pups and hunting for food. Wolves are the largest members of the dog family. They are powerful built animals that possess the strength to take down a moose. Also, wolves have the willpower to travel long distances and run up to 35 miles an hour. In addition, wolves have two layers of heavy coats. The first layer of hair is tough guard hairs, while the second layer is a dense undercoat. Moreover, wolves have a keen eyesight and can detect the......

Rabbit Run

...English 211 Rabbit, Run Is There Help? “Mr. and Mrs. Garcia, I am Officer Rodriguez, I am very sorry to have to be the one to tell you this, but there has been an accident. Your daughter was killed in a motor vehicle accident last night. As far as we can tell, there was alcohol involved”. Imagine getting a knock on your door at 2:00 in the morning, opening it up to find two police officers standing there. It is every parent’s worst nightmare. Unfortunately, this is exactly the news my parents received on January 24th, 2006. My 22 year old sister was killed by a drunk driver. To make the situation even harder to bear, he was 18, her friend, and had 3 prior DWIs. No one understood why my sister continued to befriend this kid. He was a ‘bad kid’, always in trouble, ‘no good’. These are the words people in the small community of Taos used to describe him. “He has potential, nobody has given him a chance, if I can be a positive influence and make a difference in his life, then mine will be worth it” that’s how she’d explain it to everyone who asked. On the night she was killed, she went with him to try to convince him to go home. All of the witnesses and her autopsy proved she hadn’t been drinking. When he realized she was dead, he tried to pull her lifeless body into the driver’s seat and had intended to report that she had stolen his car. He couldn’t lift her body so he climbed over her and left her hanging half out of the car. He stole her purse and......

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. ...

The Rabbit Hole

...In the story “The rabbit hole” the author Ann Beattie, challenge us to think about the conflict among family members when dealing with an aging parent with a serious illness. As a person ages In today’s society there is a role reverse between parent and child. Children are taking care of their parents and assuming all the responsibilities and decision making about their parents health care needs. The story raises a question about family relationships among family members, more specifically the relationship between a bother and his sister, when dealing with the decision concerning what is best for their mother. The author described the way both children had a different point of view on how to deal with their mother Illness. The daughter the primary care giver drove mother to all her appointment, took time off from work. Had to deal with the choice of giving up her life when she moved back home and let the love of her life go when she “ made the mistake of not marrying “ (pg 365) her boyfriend because she was having trouble balancing her love and personal life.

Rabbit and Wolves Lab

...“Rabbits and wolves” Introduction The computer simulation named “Rabbits and wolves” is about models and simple systems. In the simulation, there are three main organisms, rabbits, wolves and grass all put together in a forest ecosystem. An ecosystem is a set of organism within a defined area or volume that interact with one another and with their environment (Miller & Spoolman). A system is a collection of elements or components that are organized for a common purpose (Rouse, 2005). The purpose of this simulation is to see how these three organisms will interact with one another in the same environment. We will see how the populations of these organisms change by modifying parameters specific to each organism and how changing the start up parameter of an organism can affect the way the others grow. Objectives 1. To view and interact with a simple scientific computer model. 2. To determine how simple changes in populations of one organism will affect populations of organism in the same system. 3. To use a computer model to complete objective 2. Hypothesis Placing rabbits in a larger forest will not only allow them to grow better and have enough sustenance but also to avoid being eaten by wolves. Results The default parameters are the following: | Rabbit | Wolf | Maximum food capacity | 45 units | 200 units | Metabolism rate | 3 units/stage | 2 units/stage | Reproduction age | 10 stages | 10 stages | Probability of......

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......

Rabbits

...Rabbits by Dorothy Nimmo 1. Summary: The story is about two sisters, who had been giving a nice china rabbit each by their uncle. They’re having a tea party in the garden and it is all very idyllic. But the oldest girl is very manipulating, and manipulates her little sister, to give her the rabbit her little sister had been giving. Then the older sister decides that she wants her own rabbit back, and she gets it her way. 2. Characterize the two sisters: Kate: Kate is described, from a small girl’s point of view, as a brave, intellectual, talkative, naughty and pretty girl. I will say, that Kate is about eight or nine years old. She is very aware of herself and very manipulative against her little sister Ellen. She is probably a bully, because she seems to enjoy nagging on Ellen. She calls Ellen fat, because she is eating redcurrants and threatens to tell their mother. Kate has a great power over Ellen, and is abusing it for her own amusement. Ellen: Ellen is two years younger than Kate. Six or seven years old, is my guess. She is very cautious, a fusspot if you may. She is described as a clumsy girl who always fall over her own feet, and is all covered up with plasters. She looks up to her big sister Kate, and sees her as an idol. Ellen is imitating her big sister, and does as Kate says. Kate asks Ellen, to go to the shed and get a brush, and Ellen just goes down the path to the shed, without protesting. 3. Comment on Kate’s way to manipulate: Kate knows......

Dances with Wolves

...Dances With Wolves Dances with wolves is an important motion picture which gives us a look into the lives of Native American culture, and white America. The movie promotes acceptance and tolerance for the Lakota culture. During the film the humanity of the Lakota people and their familial bonds and tribal culture is introduced to us. These different people that are established in nature are threatened with running into the white civilization and having everything they know ripped away from them. Little do they know that they will run into a white settler who will teach them white ways, introduce them to new technology and english words, practice their own culture as well and live together in harmony, without superiority getting in the way. At first when we are introduced to John Dunbar a Lutenient who is positioned at a white soldier fort alone, it assumed that the indians are not too far off from the post, and the two cultures will eventually clash and could potentially end in a battle. We see the Lakota Sioux tribe who are friendly and accommodating, and the Pawnee Indians who numerous tribes are not accepting of other cultures even the Lakota which is surprising due to the fact that they are both indians. The only reason the Lakota Indians feel as though they have to ever fight is because the pawnee is threatheing their well being. At first when the Lakota discover that their is a white man positioned at a post close to their own homes, two leaders are sent their......

Dances with Wolves

...Dances with Wolves Tera Butler ENG225- Introduction to film Professor Daniel Burrello February 8, 2015 Dances with Wolves Westerns are stories of life and adventure in the American West a time period and way of life everyone should reflect on. Dances with Wolves(1990) is one of the most truth brought forward Westerns of our time, as it explores the ending of the Civil war and the embarks on the New Frontier that ultimately changed the way of life for most all Native Americans. This film is compiled with drama, love, loyalty, courage, and racism all with lasting impact on its audience. Directed by Kevin Costner in a simple cinematographic technique that allows the audience to experience the characters every move. This movie was written by Michael Blake and directed by Kevin Costner who also is the lead actor throughout the film. Other actors include Mary McDonnell, Graham Greene, Rodney Grant, and Floyd Red Crow Westerman. The story starts with a wounded Civil War soldier about to have his foot amputated when he makes an attempt at his life by stealing a horse and running recklessly across the open battlefield nearly getting shot. The build from this scene is that the soldiers fighting see his act of desperation and encouragement and a distraction and use the fact that the enemy is so focused on shooting him off his horse that they never see the final attack coming. The end of this scene Kevin Costner...

Rabbits

...Rabbits – by Dorothy Nimmo The short story is about to sisters who are sitting in the orchard garden and having a tea party. Both of them Katy and Ellen has been given a china rabbi by their uncle. Kate who is elder by two years has gotten a blue rabbit; Ellen has gotten a brown one. Kate Manipulate her sister to give her the rabbit she had been giving. Then Katy wants her own rabbit back, and somehow gets it again. Settings The text “Rabbits” take place in a summerhouse orchard (frugthave), the story is not real but could be something happening in real life. In the text, the girls are not only in the summerhouse but also some other place ex. The shed. We do not hear about the social environment in the text. The text is describe detailed and we get a sort of an imagination of the place the two sisters are staying in. Their surroundings makes the story peaceful and idyllic. (Does it reveal anything about the characters’ feelings? Not answered yet). Characters In the story, there are two characters involved two sisters, Kate and Ellen. We know that Kate is two years older than her sister Ellen is. Kate is the dominating sister, who is able to manipulate Ellen. From Ellen’s point of view, Kate is described as a Clever, naughty, pretty, talkative, lovable and most importantly older then she is (Page 1 line 16-17). We do not get the age of the two girls, but I would say that Kate is 8-9 years old. Kate is very aware of herself and manipulative against her little sister......

Swamp Rabbit

...The Swamp Rabbit of Missouri LaShonda Howard University of Phoenix BIO/101 August 10, 2015 Linda Mottison (2015, February 6).  Swamp Rabbit of Missouri Introduction The (Sylvilagus aquaticus) or Swamp Rabbit, a native of Missouri, is by far the largest of the cottontail family. While they are the largest, they have the smallest ears of them all. The term “cottontail” is the defining character trait of the tail of the rabbit when raised that resembles a piece of fluffy cotton. Even though the swamp rabbit looks similar to other eastern cottontails, they are larger and darker in color – dark brown, rust and sometimes black. Once densely populating the southern United States frequently along the mighty Mississippi, Swamp rabbits are found abiding in lowlands, swamps, floodplains, and marshlands. The swamp rabbit is playing impactful roles in both the ecosystem and economic system. However, the extensive hunt of the species along with human development and expansion continues to erode the habitat and creates obstacles for survival (2013).  The decline, teetering on extinction in some places, will continue unless we push the habitat needs to the forefront. One such place in Missouri is the Mingo National Wildlife Refuge in southeast Missouri. Environment Description and Role of Organism Never more than two kilometers away from water, the very moist, humid, and often hot environment of the Swamp Rabbit is the wetlands. They prefer residing in areas such as......

Dances with the Wolves

...Dances with Wolves Dances with wolves is a movie based upon John J. Dunbar’s experience going back to an old fort and along the way he met indians and learned their ways of living. Also he met a white women that was taken in by the indians and John married her. John created a strong relationship with the indians. He taught them his language and they taught him theirs. As for the name of the film, the indians gave John the name dances with the wolves. This was brought up from a wolf following John around during the movie and was loyal to him. 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. This movie focused on seeing indians from a different perspective and not just savages. Though this movie was one of the top movies on the board when it first came out, the historical facts aren’t very accurate. 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...

Chassing the Rabbit

...Chassing the Rabbit Chappisha Morgan Book Critique “Chasing the Rabbit” May 31, 2012 This book “Chasing the Rabbit” by Steven Spear was a difficult read for me, I didn’t like that it didn’t flow easily like the “Hug your customer” book by Jack Mitchell. This is supposed to be a good read book, but I honestly wasn’t impressed. I don’t like all his focus on Toyota and other industries. I’m assuming the goal of this book was to show us different challenges that organization may face while they are all on the chase for the rabbit or money or success I should say. I get that the main focus of a company is to bring in revenue and to compete with other companies in their industry, but I don’t see why he need to focus so much of the book on Toyota’s success, I get that his little stories showed us something in the end but I do feel like it was too much at times. The books message is to show how much can be accomplished with less cost. Giving us the debate of weather an even trade off is how much we give up for something we really want which is taught in microeconomics. Life is all about the trade and what we have to lose in hope of a bigger gain or the better good. This much I can agree with. I think his chasing the rabbit metaphor is a good way to look at it because when you open a business we are competing with other companies and we all start at the same beginning but we get to the ending (which is the success level) differently. I like the......
