The Impact of Rana Catesbeiana in Arizona

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.

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.

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.

My invasive species that I’m investigating is the American mink it is invasive in England. The American mink came from North America, and got brought to England in 1929 for fur farming.

The American Bullfrog is native to lands east of the Rockies. The Bullfrog was brought over during the goldrush in the late 1800s, when gold miners ate the California Red-Legged frog all the way to near extinction. After that there was a ghuge rush to bring Bullfrogs here, after that they nearly did the same thing to the Red-Legged frog. The Bullfrog has been introduced to four of the seven continents in the world, where it either eats the natives, or competes with the natives for food until the natives die out or near extinction as it happened in the

An invasive species in my state, the state of Louisiana, would be the Nutria, also known as Coypu. Nutria are a beaver-like rodent, originating from South America and popular for their fur. They are semi-aquatic with webbed feet and are known to be strong swimmers that can stay submerged underwater for up to five minutes. They are commonly found in the wetlands or burrowing in riverbanks. They are omnivores, their diet consisting of mussels, snails, and roots. They are commonly known as the river rat while they are scientifically known as Myocastor coypus.

The bullfrog, Lithobates catesbeianus (Shaw 1802), is a common aquaculture species that has become a dangerous invasive species. Considering that this North American anuran involve a great risk to native communities, its invasion is a mayor threat to biodiversity at the Neotropic. The invasion of this species is associated with different continental aquatic systems, but it displays a preference to the permanent ponds and water reservoirs. In Uruguay, three bullfrog populations were detected so far, two of which have failed to establish (a situation that seems to have happened in several cases), but one persisted and is expanding in Aceguá, Cerro Largo. Although local authorities are concerned about this invasion, no control action was implemented

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

To start, invasive species are any kind of living organisms that isn’t native to an ecosystem and can cause negative effects to that ecosystem and whatever thrives there. As a matter of fact, they are the reason for the decline of 42% of endangered and threatened species all around the world. Most forms are plants that poison the animals and causes them to become endangered. Other forms are animals killing the others and disease wiping the populations out. The plants also kill the neighboring plants by releasing poisonous compounds. As the poisonous compounds, diseases and animals spread out to various locations,

Scientists looked for extinctions caused by invasive species. They found 170 extinct animal species with a cause of extinction listed. Invasive species are a plant, fungus, or animal species that is not native to a specific location, and has a tendency to spread to a degree that can cause damage to the environment, human economy or human health. According to the NWF, Invasive species are outcompeting native species, growing out of control, and cost the economy a lot of money.

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.

One example of an invasive species is Xenopus laevis, or the African clawed frog. These frogs carry a fungus called Batrachochytrium dendrobatidis. Chytrid fungus infects amphibians with chytridiomycosis by attacking the part of a frog’s skin that contains keratin. Frogs use their skin to
