As students we have learned in school that every animal and plants can be species. The definition of invasive species is an alien species whose introduction does cause an economic harm or harm to human health. (Sarah Zielinski,2011) My own interpretation of invasive species would be animals or plants from another region of the world that don’t belong in their new environment. Invasive species are introduced into an area through ship waters, accidental release, and also by humans. Invasive species can have harmful effects to the environment such as, affecting the ecosystem; limiting biodiversity; and using resources available to the existing habitats. Invasive species are also recognized in forest and open forest habitats. An example of …show more content…
They are many reasons why species are successful at effectively living in a new environment. Species have many different characteristics that allow them to be successful in its own habitat, some of the characteristics are they have the ability to grow quickly. They have very basic eating diets. The species can spread out too many other environment conditions and survive. For example, Kudzu became known as “The mile a minute vine” and “the line that ate the south” due to its quick growth and widespread takeover. (Gonzalez) Species have the ability to have multiple offspring and reproduce quickly, gives them the ability to have a large number of their species and gives them a higher chance to dominant their …show more content…
An example of this species is an Zebra Mussels. Zebra mussels are invasive can kill native freshwater mussels in two ways the attachment to the shells of native species can kill them. Another way these species can outcompete native mussels and other filter feeding invertebrates for food. Zebra mussels are from Eastern Europe and Russia. They were brought over to the great lakes in ships. The population of zebra mussels were first discovered in the Great Lakes in 1988. Scientifically known as Dreissena Polymorpha. They are very different from Great Lake another region. The shellfish is small and has pattern on the outside of their shell. The color can change from only being dark to light colors with no stripes. Zebra mussels also have a large reproduction
Originally found in the Atlantic Ocean, the sea lampreys where first discovered in Lake Michigan in 1936. The sea lampreys can be described as jawless parasites with mouths similar to suction disks. They also have very sharp teeth which they us to attach themselves to fish in the water, allowing them to feed on their blood and body fluid for various hours or even weeks. This usually causes visible injures to the bigger fishes and kill smaller fishes. These sea lampreys contribute to the decline in the population of white fish in the great lakes.
It’s hard to manage system when there are constant changes. A large change in Lake Michigan started about 25 years ago when Quagga Mussels got into the system. The bottom of the lake is now covered with them because the smooth surface and cold water is the ideal for habitat for quagga mussels to grow on. Quagga Mussels can filter up to four liters water per day.
The Asian Carp Response in the Midwest states: “The presence of Asian carp in the Great Lakes could cause declines in abundances of native fish species. Asian carp will compete with native fish for food—native fish like cisco's, bloaters, and yellow perch, which in turn are fed upon by predator species including lake trout and walleye” (np). Another consequence is the poor quality of water that carp cause when they enter into new waters. They are known to be responsible for the unpredictable and disastrous results in habitats. As stated by Hansen, M. “Asian carp are like zebra mussels, which also prey on the base of aquatic food webs, and can thereby reorganize nutrient and energy flow with unpredictable consequences on native species” (np).
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.
Due to Minnesota having a tremendous amount of lakes, it opens up doors for new invasive species to come in and take over. A popular specie that has been taking over lakes lately are zebra mussels. Although another invasive species that doesn't get too much attention is Eurasian Watermilfoil. Eurasian watermilfoil was brought over to North America from Europe around the 1950s. It spread inland from boat users and waterbirds near the 1970s.
People will not take good care of them because they get to big and their owners get scared and release them into the wild where there is already other animals habitats without thinking there is other ways you can get rid of your invasive pet. The second reason is, Certain plant rely on animals to keep them alive in their environment in which they live in. If you take the animal away from its original environment it could affect plants that rely on that animal and could cause the animal that went to its new environment to cause it to scare an animal away that had a plant that relied on that animal. or the new animal could eat the plant that the other animal relied on. My third and final reason is, The invasive species multiply and take over the environment causing corruption and harm.
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.
After this each group tallied the same "species" together
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.
Briefly describe two possible reasons for the presence of this invasive species on the stream bank. The seeds or spores of this plant could have been accidentally introduced when goods were shipped from other continents. This plant, the purple loosestrife is native to Europe and Asia, so when goods have been transported from there, they could have been introduced to our ecosystems. It also could have been introduced unintentionally, since it was sold in packets of flower seeds for gardeners.
Invasive species have been a massive problem in Hawaii since the 17s and 18 hundreds. At first, it wasn’t that big of a deal, but the influx of invasive species grew over time, and it became a dangerous slippery slope. Species that were once alienated poured into Hawaii and destroyed indigenous species that had been native to Hawaii for a very long time. Since then, the Hawaiian people and advocates of removing invasive plants and animals have banded together to help remove these species. There has been a great global effort to remove invasive species in all places, but the hasty spread of them has made it almost impossible to eradicate a lot of them. I think my group can majorly help with this by educating you all about the seriousness of invasive species.
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
And do different species in the same locations evolve similar characteristics?" (Bender 5). Cities do provide the best testing area as they face rapid development and changes. The answer to his questions is that same populations of animals evolve according to the pressures that they face. The example of the Peppered moth where human activity caused the mostly white moths to die to the minority Black moths that would go on to survive in the city.
Salmo trutta, S. salar, Oncorhynchus tshawytscha, O. kisutch, and O. mykiss; Basulto 2003; León-Muñoz et al. 2007; Soto et al. 2006), therefore Salmonids are useful models to address how species evolve in a new environment. In this context, Rainbow trout Oncorhynchus mykiss Walbaum, 1972 is one of the most introduced and successful freshwater species due to its economic value, its ease of culture, and importance to sport fishing (Casal 2006; Crawford and Muir 2008). In addition this species is listed in the 100 of the world’s worst invasive alien species (Lowe et al.
When the habitat is viable for reproduction, the species has a better chance of recovering naturally in the
