Essay On Invasive Species

A species that is introduced to an ecosystem by humans can harm ecosystems in many ways. Animals that are introduced into a new area, could hunt a main food source for some animals, causing that population to decrease. Plants could be poisonous, or need to feed off of other plants. Species introduced into an ecosystem by humans through off the natural balance of the wildlife.

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.

What makes something invasive? Is it when the object takes over? When it reproduces to a great extent? When it takes over all of your space? These are all aspects of an "invasive" thing. Invaders cause other tiny problems along the path of their destruction that can be difficult to control. In Mark Sanchez's, "The Invaders," and Aaron Hartman's, "Kudzu: From Pretty Vine to Invasive Pest", two plants, the milfoil and kudzu, are taking over. These invasive weeds have more than just being invasive in common with each other, they also share a hand full of dissimilarities. These plants have gobs of similarities and differences between each other.

Invasive species make bad situations into worse situations. Having a species from a different ecosystem makes them invasive species. Such as a toad or even bacteria being in another ecosystem other than their natural habitat.

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 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.

There are many creative ways the of invasive species is being addressed and they are a problem. There are many different problems with invasive species. There might be problems with invasive species, but people are coming up with fun and different ways the problem can be addressed. Pythons, wild pigs, and red foxes are all a danger to different wild life. There will continually be more species even if everyone thinks they are gone, they will come back every time even if it is a different

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.

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).

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

Invasive species are organisms that aren’t native to a certain land, and result in a negative effect. The Kudzu plant (Pueraria Montana) is an obnoxious plant species that surrounds everything in it’s path, giving it the nick-name The Vine That Ate The South. Kudzu originated in Japan and was brought to the U.S. because expedition attendees from Philadelphia thought it was pretty. Removing the Kudzu plant would lead to less property being destroyed and less plants dying. I believe that we should make an attempt to remove the Kudzu plant because it is a great nuisance. Although there are some advantages to the removal of the invasive species, the limitations are more significant than the advantages.

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.

Exotic animals can easily become endangered animals. According to current estimates, a third of the world’s amphibians, one in eight birds, and a quarter of all mammals are endangered. (“Endangered Species”). On average, there are twenty-three states in the United States of America alone that allow you to legally own an exotic animal, and twelve of those you do not even need a permit to acquire them (Loria). This increases the chance of fatality, malnourishment, being endangered, extinction and other issues. Exotic animals being kept can also endanger humans while being in harm's way themselves. Examples of some popular exotic animals some people might not consider exotic are snakes, birds, monkeys, big cats, and turtles. Turtles are the most endangered in the vertebrate groups due to the pet trade. This is because once you get a turtle, you cannot release it again or else it will not survive. Second, big cats are extremely popular in the US. There are around 10,000 tigers being kept as pets. This means there are more tigers kept as pets than in the wild. Statistically, since 1990 there have been 21 human deaths, 246 maulings, and 143 wild-cat deaths in captivity. Next, monkeys are also incredibly popular. Monkeys can carry various diseases such as Herpes B-Virus, Monkeypox, Ebola, and many more. Owning a monkey is bad for the monkey and for the owner. Additionally, there are over 150,000 parrots smuggled into the U.S. every year. Birds are meant to fly and be free, not to have their wings clipped and be confined into a tiny space. They have lost their whole life, and freedom so they can be called “pretty bird” and fed little pellets. Lastly, are the snakes. Snakes are everywhere around the world, ranging in color, shape, size, and species. In the last decade, more than 12 people have been killed from boa constrictor incidents, and with even more injuries. Snakes are also very dangerous to humans. Not only do a lot of

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.
