Invasive Species In The Pacific Northwest

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.

The article “Nutria, Eating Louisiana’s Coast” goes into great detail about nutria rats and their effects on the Louisiana area. It also presents the reader with facts that prove what the author is explaining.

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.

What is an invasive species? An invasive species is a species not native to an area, in this case not native to the Great Lakes area. A non-native species is a species that originally was not in a certain location but was brought there and causes a lot of damage. An invasive species also is a great danger to the environment and can cause damage to humans, plants, and animals. In Illinois and the Great Lakes area there are more than 180 invasive and non-native species. That means a lot of damage is made into our environment. One particular invasive species is Agrilus planipennis, more commonly known as emerald ash borer.

Invasive species are organisms that are accidentally or intentionally introduced into an environment, that adapts quickly and disrupts the natural ecosystem. Bullfrogs (Rana catesbeiana) are native to the northeastern part of North America and are some of the most damaging invasive species. Many cultures around the world eat frog as a delicacy, so bullfrogs were gathered up and sold around the world. However, some of the species were introduced into countries around the world. Currently, they have become established in over fifteen countries as invasive species (Save The Frogs! et al. 2013).

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.

Before we continue let’s define the word species. The Merriam-Webster dictionary defines species as a group of organisms capable of exchanging genes and reproducing to create young. It’s common knowledge that all fertile humans are capable of producing a child, this means that all humans are the same species. Julian has already defined invasive species for you, but let me define it again. An invasive species is any non-native, living organism migrating or being imported to a land foreign to it/them. Now I think the most important part of that definition is non-native. Humans are native to every continent on earth. For a species to classify as an invasive species it must be non-native. I guess the The National Wildlife Federation might not be reputable enough for you. How about The United States National Agricultural library. A non-native species introduced to a particular ecosystem introduced by means of migration or importation. Don’t believe the National Agricultural library? How about the International Union for Conservation of Nature. An invasive species is a non-native animal, plant or other organism introduced into a place out of their natural range of distribution. Notice any recurring theme? Non-native, non-native, non-native. Humans aren’t non-native to any place on earth; so to consider them an invasive species is illogical, unintelligent, and flat out

Nutria are large semiaquatic rodents that appear to look like beavers with long, thin tails, however they are considered to be an invasive species. They survive in swamplands and typically other wetlands surrounding Louisiana. These organisms have created a problem to the Louisiana environment by creating openings in the marsh vegetation that sustains the Louisiana coastline and by weakening flood control levees that protect low-lying areas. Nutria are also known for their high procreative rates. Because of this, maintaining a well balance between the factors of supply and demand are difficult. Preventive measures and other available techniques have been presented in order to alleviate ongoing damage and to reduce the levels of damage already

Invasive species are a group of organisms that are not native to the land, and also have a negative impact on the ecosystem. Zebra mussels are one of many invasive species in North East America and Europe. These species cause much havoc for humans, and weaken food webs by even affecting zooplankton.

Similarly, sea otters in kelp forests keep sea urchins in check. Kelp roots are merely anchors, and not the vast nutrient gathering networks of land plants. Thus the urchins only need to eat the roots of the kelp, a tiny fraction of the plant's biomass, to remove it from the ecosystem.

Invasive species are one of the 5 causes of the inevitable 6th extinction. An invasive species is any kind of plant, animal, fungi, or bacteria that is not endemic to a region but, when introduced, can spread quickly and cause destruction to that region. Primarily due human activities, these species are spread by sea, air, and other ways. Sometimes these species are purposely brought to an area as a means of pesticide or other uses, but others can be introduced accidentally. When an new species is introduced to an ecosystem, it can destroy wildlife because organisms may not be evolved to defend against such invaders.

Invasive species are non- native plants, animals and pathogens that cause or are likely to cause ecological disruption, economic losses or harm to humans (Twelve invasive species of high concern in Virginia). I have chosen three examples of invasive species

When any of the species’ mentioned above are released into the wild where they are not native, they have a chance to become an invasive species. According to the Cooperative Invasive Species Management Area or CISMA, invasive species are “nonnative plants or animals that cause harm to the environment, economy, or human health” (CISMA, 2017). Invasive species are normally brought to a new area by people who want to own exotic pets or have plants that will survive in extreme weather. When the conditions are favorable to the species it can survive much better than the native species. If the species happens to find a mate to reproduce, it can grow in population rapidly. One example of this is the rabbit population on the island of Macquarie where the population went from 20,000 to 130,000 in just six

Biological invasions are generally considered an environmental threat, out competing native species and increasing community homogenisation. Importantly though, invasive species also alter ecosystems, yet little research has focused on whether invasions are a threat to their functioning or services. This encompasses two main debates: determining whether invasive species alter ecosystem functioning and, if they do, whether these impacts are positive or negative. After reviewing current literature in an effort to resolve this controversy, it seems that in most cases, non-native species do alter ecosystem functioning. However, whether this change had

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.
