Invasive species

Within the past several decades, the zebra mussel Dreissena polymorpha has made its way to the top of the list as one of the most destructive invasive species in the North American water systems. While many studies have been made focusing on the ecological impact of zebra mussels, little is known about the geographical history of their invasions and patterns of genetic differentiation among and within populations in their native and invaded ranges (May, Gelembiuk, Panov, Orlova, & Lee, 2006).…

the spread of invasives, and that this is a big issue. This process is known as ballast water exchange. Unfortunately, it doesn’t fully eliminate all of the estimated 160 new invasive species, carried over to the Great Lakes from ships' ballast tanks(National Wildlife Federation). Since the invasive species are so hard to take care of, the damage and removal can tend to cost billions of dollars. What can we do as ship owners or knowing someone with a ship? The spread of invasive species in the…

Invasive species sound like nothing, right? Like plants and animals that threaten to destroy our native wildlands are no big deal. Well, it’s a very big deal, and invasive species are a tremendously real threat to the U.S. Humans introduced invasive species to the United States, and with the damage that they do, it is vital that we stop them. “1) non-native (or alien) to the ecosystem under consideration and 2) whose introduction causes or is likely to cause economic or environmental harm or…

Science Professor Julie Allman October 22nd, 2014 An exotic predator's ecological impact on Florida ecosystems The sub-tropical environment of southern Florida supports a wide variety of introduced exotic reptile and amphibian species. The majority of these species were introduced by human activities. Irresponsible keepers, animal dealers, and the international trade has released large predators like African and Asian pythons, South American tegu lizards, and African monitor lizards into new…

Description of area: Larchwood Lake can be found in central New York, outside of Laurens New York. Buried in the woods, Larchwood Lake was a Boy Scout camp in the early 1960’s. Around 1988 the Boy Scouts sold the land to residents creating the Larchwood Lake Homeowners Association. The lake was manually increased to twice its size. Today the lake has a long almost swan like shape. According to The Biological Field Station Larchwood Lake is “near pristine.” The lake is not that deep, it has a…

The Brainerd lakes area is a beautiful tourist attraction in central Minnesota. Thousands of people come to the huge resorts and their elaborate lake houses every summer. Many people come to fish as well which is one of the main attractions to the place I grew up in. Zebra mussels have been invading some of the lakes in our area now which is alarming. They are most prominent in Gull Lake which is a very large tourist lake which has 12 resorts and 5 separate restaurants that are accessible by…

Invasive species are plants and animals or pathogens that are non-native to the ecosystem. In which under consideration and whose introduction may cause harm to the environment.(Gateway to Invasive Species Information) They come from different countries due to different environmental that factors that attract them here. Many of the animals that you thought that were native to the united states of america are not. Such as the Oryctolagus Cuniculus also known as the european wild rabbit or a…

Impact The environmental issue is how the Brown Tree Snakes are making native species extinct. This can affect the local, regional and global scale in multiple ways. This problem affects the local level because the snakes eat the species on the island weakening and eventually change the ecosystem and cause power outages for residents on Guam. This problem also affects them on a regional level because in the future the snakes might spread to other regional island and also weaken their ecosystems…

environment, Invasive Species. Invasive Species can include any type of living organism that is not native to a certain ecosystem which can cause harm to that newly inhabited ecosystem. The harm that can cause doesn't always just affect the environment but the economy and even human health. Invasive species cause harm to a newly inhabited ecosystem in many different ways. When introduced into a new ecosystem it may not have any natural predators which will lead to increased population of the…

non-native species becomes controversial. The major issue that most people worried about is that whether non-native species threaten the natural environment. Mark Sagoff (2005) asserts that non-native species are not necessarily harmful. In response to Sagoff’s viewpoint, Simberloff comes up with opposing opinion that “major environmental impacts of non-native species…have both been demonstrated and judged by the public to be harmful” (Simberloff 2005, p595). To prove that non-native…
