Are invasive species harmful or beneficial for an ecosystem? Invasive species can have an overall negative or positive effect on the environment around them. It is easy to create a bias in viewpoints when looking into different topics of invasive species. Many people believe invasive species are destructive to the environment they inhabit. While, others believe they take on new beneficial roles that benefit the resources around them. As you look at the influential features of different invasive species it will open up insight on whether or not invasive species are beneficial for an eco-system.
An invasive species can be defined as an organism that is introduced into a new, non-native environment. Invasive species are often described as an

Invasive species affect biodiversity as well as habitat eco structure in the environment. The highest threat invasive species pose to biodiversity is the threat on endangered species. Nearly 50 percent of the 1,900 endangered species are endangered because of invasive species and the ways in which it can alter an ecosystem. Invasive species are currently the second leading threat to biodiversity. Invasive species alone, have a stronger negative affect on biodiversity than forest clearing, disease and pollution combined. For example, the Nile perch is a species of fish that was introduced to Lake Victoria as another resource for food. This new non-native fish quickly became a devastating predator and has eliminated over one hundred species of fish. The Nile perch was able to do this because they reproduced rapidly and they could out compete native fish for habitat and food. Invasive species are aggressive species that can control a newly introduced ecosystem by spreading quickly and taking over the …show more content…
The Asian oyster is an invasive species that helps benefit the ecosystem it inhabits. The Asian oyster filters out water pollutants, improving the water quality they live in. They also grow fast and prevent disease which can allow the oyster industry to revitalize. Often, efforts will be made to remove an invasive species, which can have a negative effect on an ecosystem with a newly adapted balance. These attempts funded by the government to remove a species could just be a waste of tax dollars and
The other predators are introduced animals. The first one was the Dingo. This was introduced as a domestic Dog several thousand years ago; it became feral. More recently, the Europeans have introduced Foxes for recreational hunting. Cats are also a problem.
Invasive species are “species that is non-native to the ecosystem whose introduction is likely to cause economic and environmental harm”. A example of Invasive species would be the Zebra Mussel. Zebra Mussels or also known as Dreissena polymorpha is a small freshwater mussel. The Zebra Mussels can live up to three-nine years which can grow up to 2 inches. These mussels attach to hard surfaces such as rocks or boats.
The location of where the oysters are grown and the conditions of that environment are extremely important to the oyster industry. The Croxtons explained that the oysters are put in cages that are elevated above the muddy sea floor so they can eat better food and have a better lifestyle. Another theme of geography that is used is human-environment impact. The Croxtons are impacting the environment and ecosystem of Chesapeake Bay in a beneficial way by harvesting oysters. The oysters help filter the water in the
There are many invasive species that are affecting the Everglades by invading the ecosystem. Many of these species were brought to the everglades by people and animals. They are changing the ecosystem and are competing with natural native inhabitants of that area. The native species have to adapt to the change or move to another area to survive. Both plant and animal species have invaded the area within the Everglades.
Isaiah Edgerton Florida's Everglades is a wetland ecosystem that is home the many animal and plants. Florida's Everglades native species are being threatened by invasive species such as pythons and there offspring who have been released in to the wild by pet owners. Before people knew the benefits of Florida's Everglades people wanted to drained it to get rid of the disease caring bugs, residential and industrial development, farming land, and dumping which caused pollution. Now people know the good o Florida's Everglades out ways the bad as it can buffer storms, provide hunting and fishing, and provides jobs and attractions.
THE ZEBRA MUSSEL INCIDENT The Zebra Mussel Incident Zebra Mussels are an invasive species which now dominate the Great Lakes region, they were introduced in the 1980’s and ever since then their quantities have increased dramatically. Since the time they arrived they have caused many problems including problems in the ecosystem and with the economy. Human’s have been trying ever since their arrival to eliminate or reduce their quantities but not much progress has been made. Right now Zebra Mussels are one of the biggest issues affecting the great lakes.
Eurasian Watermilfoil Invasive species are becoming a big problem in today’s society. They are not native to the local habitat. A lot of times, invasive species are extraordinarily good at adapting to the environment. However, they can block out and do harm to other native organisms.
One of the largest invasive species in the U.S. and the world is the Burmese Python. According the USDA, “invasive species are plants, animals, or pathogens that are non-native (or alien) to the ecosystem under consideration and whose introduction causes or is likely to cause harm.” The Burmese Python, scientifically called Python bivittatus, is native to the jungles and marshes in Southeast Asia. This animal now has a large population in the Everglades of Florida thriving with its wide availability to prey and weather like it is in Southeast Asia. What are the benefits and drawbacks of removing the Burmese Python out of the Florida Everglades?
An invasive species is defined as a species that isn’t native to a country and has negative effects on our economy, environment, or health. The species I am researching is the Asian carp. Its scientific name is Cyprinous Capario. The Asian carp live in many different areas around the United States, such as the Great Lakes area and the Mississippi River. Lake Michigan is home to very diverse populations and species.
Invasive Species Invasive, alien species, those which colonise, expand and out compete native species (Smith & Smith, 2009), are a major threat to our habitats, terrestrial and aquatic species, and biodiversity. Agricultural and leisure industries are affected as well as conservation welfare and the continued wellbeing of man, flora and fauna. Whole ecosystems can be distorted and the economic cost of awareness, prevention and eradication systems is substantial. Most invasive species have been introduced by mandeliberately or otherwise. As an island, Ireland has been subjected to less invasive species than larger nearby land masses e.g. Europe, but islands have a less diverse species population and are therefore more vulnerable when invaded.
A drastic change as we can see that more than half of the Everglades has disappeared. Along with the disappearance of its land and water we see that animals have been effected to. The Everglades is an environmentally diverse location that holds many different habitats and in those habitats lie native, invasive, and endangered species. Throughout this speech you will learn just what exactly is happening to the precious animals of the Everglades.
They’ve crippled the Everglades’ populations of opossums, rabbits, bobcats and foxes, thus dominating the food web to such a degree that there’s not much of a web anymore. Invasive pythons aren’t the only non-native species that threaten the Everglades ecosystem. There are invasive plants too, hurting the balance of the Everglades, not only choking out native species (some vine-like plants actually grow over original trees and plants), but growing so thick that they block water flow and movement of
Invasive species are a big problem to the United States ,because they can cause billions of dollars in damage. In this paper it will reveal some of the most known invasive species in the Florida everglades. The different Invasive species that will be discussed are the Giant African Snail, the Brazilian Pepper Tree, and the Cuban Treefrog. The first invasive species is the Giant African Snail. It originated from Africa and was first presented to Florida as being a pet.
Poaching and illegal hunting can cause an off set in the ecosystem by overhunting animals. When one animal population decline drastically, other organisms are affected too. The decline in native predators is the main cause for overpopulation of animals like deer. Deer overpopulation has led to rapid decrease vegetation life causing other animals to be put at risk. Removing predators from the food web disrupts the entire balance of an
But are non-native species always harmful? In the northeastern USA, the dominant earthworms arose from non-native species in the nineteenth century; they have enriched the soil. Other non-natives with positive benefits include honeybees, plants that feed butterflies, and non-native fruit trees that feed birds. And there can be plus-minus effects. Even the infamous zebra mussel has clarified water and increased fish populations of some
