Recommended: Introduction of Yellowstone Park

The discovery of widespread trophic cascades has been one of the most exciting scientific findings for the past half century. A trophic cascade is an ecological process which starts at the top of the food chain and tumbles all the way down to the bottom. An example of this is the Yellowstone national park in the United States when wolves were reintroduced in 1995.
Before the wolves turned up, they have been absent for 70 years. As a result, the number of deer, because there was nothing to hunt them had built up in the Elliston park. Despite efforts by humans to control them, managed to reduce much of the vegetation there to almost nothing. As soon as the wolves arrived, although they were few in number, had the most remarkable effects. They

    This makes them seem less menacing and scary like the first article makes them look. Sharon Levy says in part "It is only in the two decades that biologists have started to build a clearer picture of wolf ecology….Instead of seeing rogue man-eaters and savage packs, we now understand that wolves have evolved to live in extended family groups.." (ll 19-22) This article also explains the positive overall effects of the wolves moving back to Yellowstone. Not only did the wolves have a new home filled with beautiful elk for prey they were also protected from hunters. This changed the attitude of the wolves as well as their population, of course their population grew and stayed more

    Fig.3-This food web shows that Pandas are prey to jackals and leopards. Photosynthesis is the beginnings of the food web as it produces the energy to help plants grow, which are the primary producers as highlighted in green. The Panda comes under the secondary consumer, as it uses photosynthesis to produce its food- bamboo. Cubs become a prey to other animals such as leopards and tigers which are known as the apex consumers. Decomposers listed on the right include bacteria and fungi which break down dead plants and animals.

  • Deer Overpopulation and Some Proposed Solutions

    1340 Words  | 3 Pages

    ...I think that repopulating wolves in an area where they might have to deal with people is kind of a feeble-witted idea. Wolves are not an animal with a great reputation, even though they might not deserve that reputation most people do not like. I think that people as a whole would probably rather have deer in their back yard rather than wolves. Therefore, the questions what can happen, what should happen, and what will happen, with the deer problem all three have different answers. These answers will differ due to the area that the deer are in and the peoples' feeling towards these deer. It is too bad that there is not one perfect solution to the deer problem. Maybe in the future there will be, but until then we will have to deal with each problem that comes up individually.

    The wolves’ were hunted in late 1800 s’ and early 1900‘s in the United States because farmers wanted more land for their cattle’s to graze upon. As farmers were moving out west they felt threaten that the wolves would hunt their cattles so the farmers thought that the best solution would be to take them out of the picture. This was possible because at the time there were no government regulations on hunting....

  • Reintroduction and extirpation of the Gray wolf

    1083 Words  | 3 Pages

    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

  • Reintroducing Wolves to Yellowstone and Idaho

    1914 began the official war of the wolves. This year Congress officially approves funds for the eradication of wolves, cougars, and other destructive animals. Wolves were declared destructive to agricultural and big game interests and formally hunted. Nearly a century later, in 1995, wolves were reintroduced to Yellowstone National Park and Idaho's Frank Church-River of No Return Wilderness(Phillips, 1996, p.20). The reintroduction of wolves in Yellowstone National Park did not end the debate of whether wolves should stay or go. Advocates for wolf reintroduction say the wolves control elk and deer population numbers; preventing the destruction of ranchers cattle and the land. Opponents say the wolves kill elk and deer that could be hunted. Ranchers fear the wolves will kill their livestock decreasing profits.

  • Impact of Sea Otters on Community Ecology

    1490 Words  | 3 Pages

    Introduction Sea otters (Enhydra lutris) are marine mammals capable of spending their entire lives in water. Being carnivorous in nature, they feed on sea urchins, crabs, fishes, mussels and clams. They are referred to as keystone species due to their profound impact on marine ecology. The interaction between sea otters, sea urchins and kelp forests has been studied as a model for the impact of predator-prey interactions on community ecology. Sea otters are keystone predators, whose presence has a far-reaching influence on the marine food web by affecting the populations of sea urchins, which indirectly affects the populations of kelp forests & other marine organisms.

  • Persuasive Essay On Deer Hunting

    1590 Words  | 4 Pages

    In the last decade, from the Rockies to New England and the Deep South, rural and suburban areas have been beset by white-tailed deer gnawing shrubbery and crops, spreading disease and causing hundreds of thousands of auto wrecks. But the deer problem has proved even more profound, biologists say. Fast-multiplying herds are altering the ecology of forests, stripping them of native vegetation and eliminating niches for other wildlife. ' 'I don 't want to paint deer as Eastern devils, ' ' said Dr. McShea, a wildlife biologist associated with the National Zoo in Washington, ' 'but this is indicative of what happens when an ecosystem is out of whack. ' ' The damage is worse than anyone expected, he and other scientists say. Higher deer densities have affected growth, survival, and reproduction of many plant species which have aesthetic, economic or ecological value. In some cases, many species of trees have also been shown to have reduced growth as a result of high deer density (Environmental Benefits of Hunting, 1). Deer prefer certain plant species over others and frequently feed on economically valuable tree species. For example, they prefer oak and sugar maple seedlings, as well as acorns, over less palatable species like American Beech and striped maple. Thus, less marketable species are more likely to survive to maturity,

    The wind wailed through the towering pines of Grand National Park. The sun illuminated the landscape. Those pines were more than five hundred years old. They stood unchanging like the forest itself. The animals lived in a flawless balance with nature. No humans had ruined this pristine wilderness for some time. The trails overgrew with shrubs. Gathering, clouds brought an ominous dread to the forest. It became darker by the minute. Suddenly, lightning brightened the terrain. As the rain pummeled the forest, most of the animals darted in fear. Not all the animals were terrified of the storm. The bear roared in delight.
