Invasive Species Essay

An invasive species has entered Maryland’s waters and threatens to dramatically alter the balance of the aquatic ecosystem. The Northern Snakehead fish, native to Asia and Africa, is a voracious predator, competing with native fish at all stages of its life. The juveniles will consume zooplankton, insect larvae, small crustaceans and other fry fish. Adults eat fish, crustaceans, frogs, small reptiles and even birds and mammals. Snakeheads aggressively protect their young. They are also air-breathers which allow them to survive on land for as long as four days and migrate up to a quarter mile over land making control difficult. Snakeheads carry a disease, Epizootic Ulcerative Syndrome, and there is concern this disease may be transmitted to native fish. The snakehead fish was probably intentionally released in the U.S. by aquarium owners and through the live food fish trade attempting to establish a local food source. To date, the snakehead fish is found in seven states with reproducing populations documented in Maryland and Florida. In Maryland, they have been captured in the Potomac River and tributaries. The Maryland Department of Natural Resources (DNR), the U.S. Fish and Wildlife Service, and the Biological Resources Division of the U.S.G.S. are all involved in monitoring and eradicating the snakehead fish. Maryland anglers can help by learning to identify the snakehead fish and by removing it from the ecosystem. As further incentive, Maryland DNR has offered

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 come in many forms; they can be plants, animals, insects, fish, fungus, organisms, and bacteria. Invasive plants are those which cause environmental, economic and human harm and originate from another area or region. They are a complex and difficult problem to tackle. There are more than 4,000 plants species found in Florida, of those 1300 or more are non-native or invasive. Many invasive species are taking over Florida’s waterways disrupting their natural ecosystem by outgrowing and replacing Florida’s native plants. Relieving the damage they cause is not easy, but scientists and members of the communities being affected are finding that it is achievable, as long as everyone works as a team to address the issue.

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.

Research Strategy: In order to back my idea I will find several informed and scholarly articles, backing my theory. This includes looking at the effects invasive species have on the native ones. I will look at both sides to accurately come to the final conclusion. The most accurate information will come from books published on invasive species. These books can be found at local libraries and online libraries.

When you think of invasive species possibly common invasive animals like the goby or zebra mussel comes to mind, the last thing you would think of as aggressive, habitat destroying, and invasive is a large beautiful bird the mute swan. Mute swans originally from Europe were brought to America by early explorers and colonists and released them here when no one thought that their messy eating habits and their aggressive behavior would affect native organisms. That was a long time ago before they started to overpopulate. Mute swans are very large birds and they raise many cygnets (baby swans) every year and the cygnet survival rate is very high that is just

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.

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.

They used more than two hundred species of plants, mostly seed and root plants. Each autumn they gathered nuts from pine groves and storing much of the supply for winter. Early spring was a difficult time because there weren't much left of these

There are many invasive species that populate Florida. An invasive species is defined as a plant, animal, or fungus that has come to occupy a location aside from its native grounds. Often times, because Florida is not their homeland, these animals play a negative part in the ecosystem. Because of this, the citizens affected are often forced to seek means of removing these animals to eliminate their negative effects. The Burmese Python, the Green Iguana, and the Wild Boar are just a few examples of some of the invasive species that can be found in Florida.

The St.Lawrence river is a large tourist attraction for northern New York. With invasive species being introduced to the river and the land surrounding they have affected the way the river looks and the species that are in it. Any plant or animal found outside of its normal range is considered to be invasive to the area it is now located. There has been an estimated 163 invasive species that have been discovered in the Great Lakes and the St.Lawrence since the late 1800’s. Of the 163 species that have been unintentionally introduced to the area, 85 of them reside in the St.Lawrence river. The variety of non-native plants and animals in the St.Lawrence river and surrounding land have had a continuing negative effect on the native ecosystem.

Plants can change by themselves when they are purposely grow and given the care they need, wild almonds are poisonous, the Romans were the most successful at this

With the increasing amount of disturbed habitats, invasive species could soon become the leading cause of ecological degradation (Soulé & Orians, 2001).  Invasive species can alter habitats in a number of ways.  Changes in the physical structure of the land are the most visually obvious.  Examples include narrowing stream channels, reducing sand supply to dunes, and stabilizing surfaces such as mudflats, and each invasive species goes about these changes in their own way.  For instance, the burrowing activities of Australian isopods cause the banks of tidal channels to collapse, leading to the widening of channels and the loss of vegetated salt marsh (Cox, 1999).  On the other hand, Japanese mussels that have invaded the San Diego area are stabilizing mudflats.  Although reaching Southern California in the 1960s,

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.
