The Five Causes Of 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.

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.

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.

An introduced species is a species that were intentionally or accidentally transported to another area in consequence of human activities such as planes, ships, heavy water pulling it away from its natural environment. These organisms do also commence becoming invasive after they are shipped on purpose to be supplied as exotic pets, decoration, food for livestock or humans, or way to eradicate native `pests.

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.

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.

Invasive species are organisms that harm a new environment that they are not native to. Many invasive species like Eurasian milfoil are easily able to reproduce and can do so fast. Due to this, the limited space in a body of water or area of land is quickly taken over by the invasive species so other native plants face the risk of death or even extinction. Overall, these invasive species can do great harm to an ecosystem or an economy, causing problems that are destructive to numerous organisms.

An invasive species is an organism that is not native to a certain area but it resides there anyway (What is an Invasive Species, 2016). There are many of these invasive species that are now in Florida. Such as the Muscovy duck, the Burmese python, the Asian sword fern, and many others. Invasive species can be a huge burden on nature, and society. This is why certain species that are not in this region of the world should stay out.

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.
