Keystone Species Research Paper

Climate change has affected us in many ways, but it was even more influential on organisms and their community. The Earth is gradually heating and we are left to deal with the consequences. Homes are being destroyed, organisms are dying, and resources are running low. Since 1880, Our Earth’s temperature had increased by about 0.8 degrees Celsius. Climate change is affecting the Earth and scientists say that one more degree will greatly affect people from all over the world. There are many consequences of climate change and each one has a great impact on all of us, but organisms’ homes are being destroyed and thousands of species are dying out. These organisms are imperative to our world and how it functions.

Ecology is how organisms interact with each other and the environment. The Lion King is linked to ecology by showing how organisms interact with each other and the environment. My three topics are how symbiotic relationships are important to a community, how limiting factors affect a community, how communities respond to abiotic or biotic factors, and how this is linked to the movie and Ecology. Symbiotic Relationships are interactions between two species and how they affect each other. There are three different types of symbiotic relationships Mutualism, Commensalism, and Parasitism.

Not only will climate affect the ecosystems but will also affect the animals. Climate change affects habitats for thousands of species. Animals that are affected by this would either have to adapt to the new environment or roam other places. Climate change can change life cycles for animals and

Potential unintended consequences include diversion of foods (corn and sugar cane) from human consumption, by creating scarcity and increasing food prices. Humanitarian food aid could dwindle. Conversion of forests to croplands can increase carbon dioxide levels, and threaten

plants can't change and adapt along with the rapid warming of the earth, which will

The article discussed the changes in many habitats due to anthropogenic activity. Anthropogenic is an adjective that describes changes in nature due to the people. Next, this article discussed climate change and the impact that it is having on species like clams, and fish due to ocean temperatures rising. The article also addressed carbon dating of fossils to look for cause of extinctions. Human development and agriculture have had a tremendous impact on the population of many species that are terrestrial. Deforestation is a big problem that has caused a decline in the bird species. Commercial fishing in many areas has led to a decline in fish populations. Furthermore this article

A keystone species has a high impact on a community by keeping an ecosystem together. Most often Beavers, Bears, and Bees are just a couple of keystone species.

The audience of this book is presumed to be the general person who is not fully intact with the ideas that he or she is disrupting the ecosystem and is not aware of the effects they are doing as a whole. The book argues that no ecosystem is completely inert as things such as climate changes or drought can also affect the enviorment. Without human interaction an environment can still have issues, but the introduction of human life and economy does take a grave toll on the climate. These are irreversible effects that mankind are doing to the ecosystem. The English

Issue: The environmental issue that I have chosen is the impact that invasive species have on the environment. The impact that invasive species have on the environment is vast, yet little is done about it. This issue is extremely important and will impact the world for generations to come. In this paper, I hope to learn about the effect they have on environment and what we can do about it.

Yellowstone National Park is located mostly in Wyoming but spreads into Idaho and Montana. Yellowstone national park has a Taiga biome. Taiga is the largest terrestrial biome in the world. It is primarily coniferous forest or boreal forest. The North American Taiga is at high elevations, in the mountainous western region. Within this park, there are various species of consumers, producers, prey, and predators. One very important species is the gray wolves. The gray wolves are one of the keystone species in Yellowstone National Park. A keystone species is a species that has a large effect on a community relative to the abundance of the species. This means that as the gray wolf population increases or decreases in this area, it will have some drastic effects on the entire community.

In the ecosystem organisms rely on each other for food and protection. The Food chain is like a pyramid you have the producers, primary consumers, secondary consumers, tertiary consumers, and quaternary consumers. It’s an almost perfect balance and if any level were to just stop existing then the food chain would be destroyed. An example of organisms relying on others is an issue of isle royale were the wolves and moose population are in jeopardy. This relationship is important because without the other animal the population would die.

A keystone species is a species that has a disproportionate effect on its environment relative to its abundance. Such an organism plays a role in its ecosystem that is analogous to the role of a keystone in an arch. While the keystone feels the least pressure of any of the stones in an arch, the arch still collapses without it. Similarly, an ecosystem may experience a dramatic shift if a keystone species is removed, even though that species was a small part of the ecosystem by measures of biomass or productivity. It has become a very popular concept in conservation biology.

Keystone species are species that greatly impact the ecosystem that they are a part of. These impacts can come from all different components of the ecosystem, but ultimately they change the way the whole ecosystem functions. There are many different examples of keystone species, often times keystone species are found at the top of the trophic pyramid because they have the largest influence over the other species and the environment. However, many keystone species are not the top predator, in fact there are many species that are not predators at all, but still change the whole dynamic of the environment around them and are thus considered keystone species. Two examples of keystone species are elephants and prairie dogs.

What is the meaning of a keystone species? Keystone species are species with an integral role in maintaining the balance of an ecosystem (Dunn). Changes to a keystone species will cause a drastic change in the ecosystem. There are many different types of keystones, like the keystone modifier, which affects the ecosystem habitat more than the species themselves (Whittaker P.5). Keystone species are important to identify. According to Villy Christenson, since keystone species are important to an ecosystem, identifying them is crucial in keeping the ecosystem stable and diverse (Libralato). Keystone species are an essential concept in an ecosystem and understanding them is important

First, defining keystone species so as the reader will gain a better understanding of their purpose and the species representing the different bio domes. “The definition of a keystone species states, their species whose purpose/ role and the presence has disproportionate effects, within the ecosystem and another organism within the system” (keystone species. (Nod). The species are the dominant predator whose existence is important in the different bio domes.
