Invasive Species Research Paper

An invasive species is a species that comes out of its natural environment, and enters another. These animals are usually very bad for the ecosystem and may cause an unbalance. These animals usually come in with many competitive advantages and can easily dominate any competition. This will give them the ability to eat as much as they would like without being threatened in any way. This could possibly diminish many populations and end an entire ecosystem.

Humans have caused another extinction, one that could possibly take us down in the process, species are exponentially going extinct because of habitat loss, species exportation, and invasive species bullying native species. On the other hand, scientists are trying to safe guard native species, keep animals in captivity whether it be for the animals well-being or for research, and widespread invasion. In this essay I will be comparing and contrasting “What Everglades Pythons and Other Invasive Species are Trying to Tell Us,” by Julia Whitty and “The Sixth Extinction,” by Jeff Corwin.

Invasive species are very common all over the world. Invasive species are an organism that lives in an ecosystem in which they don’t belong. Invasive species are not only dangerous to people, but also the ecosystem and must be removed.

One environmental issue that the great lakes watershed has been exposed to is invasive species. An invasive species is any organism that is foreign to an ecosystem and causes harm (United States Environmental Protection Agency, 2016). In ordered to be classified as foreign they do not have to be from a different country but they just must be a non-native to an established ecosystem. Some of the species travel at their own will but they primarily spread through human activities unintentionally. As we import and export goods, or travel, some uninvited species may ride along and travel to new places. Organisms can be stowed away in ships or products like wood. Some ornamental plants may

Invasive species are animals, plants, or fungi that are non-native to the place they are currently in. Some non-native species are not invasive, but if the organisms cause harm to the native species, then they become invasive. Some invasive species on the Pacific Northwest are nutria, bullfrogs, and yellow star thistle. These plants and animals ruin the ground, eat whatever they can fit in their mouth, and can cause diseases. These invasive species don’t help the environment or the organisms living in the Pacific Northwest.

Significance: The question of whether or not invasive species impact the environment is an important one. The answer affects everyone. In today’s world, we take the outdoors for granted. People don’t realize how much it does for us. It provides economical resources, areas to relax, and oxygen for us to breathe. Without these simple things our lives would change drastically. Life as we

Invasive species don’t just cause monetary damage, they can completely disrupt and destroy ecosystems. Invasive predators like the brown tree snake can hunt native species to extinction because these species have not evolved defences against them. Even herbivores can cause indirect damage by feeding on the same plants as native herbivores therefore taking away their food sources. Plants can cause damage as well. Through various strategies they can take over the land where native plants would normally grow diminishing native plant populations. No matter what kind of creature an invasive species is it can still cause damage.

An example of an invasive species is “Cane Toad.” The cane toad was supposed to get rid of sugar cane pest, but then it came a pest. It only has a few predators outside from where it lives.But when animals try to eat it a discharge of poison goes on it’s skin and the predator gets poisoned and dies in a few minutes.Also it has been released into out of zoos on purpose.The cane toad used to live in South America and mainland middle of America, now it has been moved to Oceania and the Caribbean also North Australia.What people do is they eat toad and make soup of their eggs but this ends up killing them.

Invasive species have been brought into the United States, some on purpose to help fill a needed use and then latter getting out of control and creating a mess of what they have done to waterways,

It is no question that invasive species cause more damage than nourishment. They have caused harm on every continent on this planet and are a threat to their ecosystems. The key to successfully managing invasive species is to understand what they are, how they arrive here, and the damage they cause. That way we as a society can recognize the threat that they pose to our ecosystems and manage them. Step one in successfully managing invasive species is to understand what they are.

The invasive species are species that are moved to a different environment. The example of Invasive species are the German Yellow Jacket. They are a species that are "alien" to their new environment. The German Yellow Jacket always harm people and cause fear. Whenever, they sting people, these people always end up with swollen limb. These species eat insects and even eat human's foods such as soda. The German Yellow Jacket's predators are ants, raccoon, and skunks. Although ants are super small, but they can eat The German Yellow Jacket. They are also known as Vespula Pensylvanica. Lastly, they were first discovered in U.S. during 1970s.

Evolution occurs when natural selection elaborates and diversifies organisms over long periods of time. Natural selection acts on a natural (environmental and non-environmental) variants and drives evolution over time through the development of genetic variants as species adapt to different environments. Minor alterations in genetics can be observed in organisms that are more favorable for their particular environment. This is what is responsible for the evolution of species. Speciation is simply the formation of new and distinct species through the course of evolution driven by natural selection. Thus, biodiversity or the variety of all life on Earth is simply a direct result of evolution. Biodiversity is important to the survival of most ecological communities.

Influence on ecosystems range from human causes like the bulldozing of a forest to natural causes like a fire or a flood.  In recent times, the introduction and spread of invasive species has transformed native communities rapidly and, in some cases, created irreversible damages.  In the Earth’s history, changes have often occurred in the ecosystems.  For example, glaciers and the retreat of glaciers cause wide-spread changes.  However, although change is a constant in ecosystems, animals and habitats often cannot adapt to the rapid alterations of non-natural stresses.  Harm to the environment from the introduction of invasive species occurs through changes in the habitat and declines in the native species.  Invasive species

The biodiversity effects of non-native invasive species have been described as “immense, insidious and usually irreversible” (Veitch and Clout, 2002). There is significant evidence proving that invasive species can cause severe economic, environmental and ecological damage (Mack et al., 2000). A lot of time and research has been devoted to dividing the world into regions with distinctive habitats and species. Numerous pathways, mostly anthropogenic, are breaking down these realms and facilitating the ecological and biological invasion of non-native species.

Invasive species are organisms that are not native to an ecosystem and cause harm to it. These organisms are capable of bringing about a great deal of damage to the ecosystems they are foreign to. This can range from disrupting the growth of the environment it has taken over to completely decimating other species. The introduction of invasive species to new environments often involves humans. The way that invasive species are introduced to a new environment varies greatly. Invasive species may be introduced by something as simple as humans accidentally tracking species into a new environment from the bottom of their shoes, or something bigger like destroying an ecosystem to clear the land, forcing the species that lived there to flee to a new ecosystem that can be disrupted by the presence of a new species.
