The Effect of Invasive Species The piece I chose to do my literary analysis on was the article, The Truth About Invasive Species, written by Alan Burdick. The article states that invasive species are all around us, but the area with the most prominent amount is the suburbs of Miami. It goes into detail about how abundant invasive species are in this area. Most people who would see a strange animal in their lawn or area would be bemused, however for the people of Southern Florida, this is a recurring scene. Burdick states that “virtually everyone in the South Florida, including Hardwick, has a neighbor with a backyard menagerie of lucrative critters on hold for resale”. Burdick describes both how an invasive species is introduced into an ecosystem, and the impact the have on other species upon their arrival. …show more content…
This is because there are so many species close to each other, but little expertise managing them. Since so many animals escape each year, it is hard for people to apprehend all of them, which leaves them to reproduce and increase their numbers throughout the ecosystem. Sometimes, people get exotic animals as pets, and when they don’t want to care for them anymore, they let them loose into the wild. This poor and unsafe behavior can also wreak havoc in the ecosystem. The issue with this is that people will recognize that a lion in the road is out of place, however, people would not notice a new plant or a small tree frog. Not all evasions are bad per say; Burdick talks about how “marine environments turn out to be particularly absorbent to-and forgiving of-alien species.” In other words, certain biomes are capable of accepting and thriving with newly introduced species. If this is true, then why are invasive species notorious for being destructive in new
Invasive species are non-native organisms that occupy habitats and disrupt the natural ecological cycles of the habitat. They threaten the biodiversity of an ecosystem and are biological pollutants Invasive species introduced into new habitats usually maximize their reproduction in their new home and crowd out native species. Their lack of natural predators in their new community allow for a proliferation in growth and expansion as a result of their abundant food supply. Once they are established, invasive species can rarely be eliminated because their new habitat is favorable for their survival.
The invasive species, the Burmese Python has done irreparable damage to the Everglades National Park in Florida. A steady decline in mammals has been observed since the introduction of Burmese pythons occurred. Burmese pythons were first introduced into the United States as part of the pet trade which then led to the escape or intentional release out into the wild. The first notation of these species arriving was in the year 2000. However, within just eleven years this invasive species had done such a large amount of damage to Florida’s Ecosystem that many species had gone almost completely extinct.
To begin with, going beyond the contrast in the atmosphere of the swamp, the two analyses are even contrary with the most quantitative observations. However, In the first passage, the swamp is described to be home to 175 species of birds, and yet in the second passage, it has shockingly hosted a massive immigration, now being home to 225 species of birds. The writers differ extraordinarily in their views of the
Nonnative species can also be called alien, exotic, or nonindigenous. Their presence is due to humans dispersing them to other locations beside their native habitat, or by humans creating environmental conditions that allow their growth. When nonnative species begin to take over a new habitat and displace native species, they are then termed an invasive species. Nonnative invasive species are one of the biggest threats to ecosystems in North America (Cox, 1999) because they are able to have an impact on many levels, including ecosystems, communities, and populations (Cushman, Tierney, & Hinds, 2004).
Exotic pets threaten the safety of the community for they pose potential risks of injury and fatality. Natural animal instincts and lack of proper care can trigger destructive behaviours of animals, injuring their owners or other community members. There has been a total of 543 human injuries and 75 deaths as a result of exotic pets, including 52 year old woman killed by a Bengali tiger (http://channel.nat......). These numbers illustrate the risk that exotic animals pose to owners and community members. Keith Gisser, an exotic reptile owner claims he's “not the kind of animal owner neighbours need to worry about”, yet Brian Johnson Gisser's neighbour says on of the reptile owner's snakes escaped into his backyard (www.wkyc.com....). Injury and fatalities are a risk, endangering the community when exotic animals are kept as pets which is yet another reason why owning them should be illegal.
Global change is taking place every day; therefore, it is important to understand how human activities and behavior alters the biodiversity and functions of ecosystems. Alien species is a stimulator of major changes in ecosystems (Vila et al. 2011). An invasive species, is a non-native plant, animal, or fungus that moves to a new ecosystem in a foreign environment. Invasive ecology explores how the invasive species affect the economic, environmental, and human health on the new environment. For example, invasive ecology studies how an invasive species tends to crowd out and sometimes replace a native species (Richardson and Pysek 2008).
...r controlled activities. Natural upheaval such as fires, floods, tornadoes, and tree falls also provide way for invasive species to grow. The huge change brought upon the Florida landscape over the last few hundred years has set things out of balance. Without exotic species, native species and ecosystems would normally benefit from natural disturbances because they provide a chance for genetic mixing and nutrient recycling to occur.
Emma Marris’ blog, “In Defense of Everglade Pythons,” exhibits that humans have controlled the relationships between the already existing ecosystem within the Florida Everglades, by the latest introduction of pythons, “It’s the blame-the-invasive species narrative…”(Marris). One major method that people have favored unknowingly at times to manipulate nature is introducing a new species to an already working ecosystem. Therefore, people have controlled nature significantly in the U.S. since 1492, when Christopher Columbus sailed the ocean blue. Humans have altered environments and how that new species will develop. They have overpopulated and underpopulated current places and animal inhabitants. And they have even changed environments for
All discussions regarding the phenomenon of invasive species will inherently result in the consensus that they are an unwanted or an even evil entity. Ever since the age of exploration humans have been primary dispersers of these so called “exotic” species (Mooney and Cleland 2001). Famous examples include the release of cane toads in Australia (Urban et al., 2008); the rainbow trout (Fausch 2008) and the Japanese Kudzu vine in the southern U.S. (Blaustein 2001) and zebra mussels in the great lakes of Canada (Nalepa and Schloesser 1992). However, documented marine invasions compared with
When people think of invasive species they normally do not think of the human species, but why not? There is a large debate about whether or not human are an invasive species. Before people debate about whether or not the human race is an invasive species they should know the definition of one. The legal definition of an invasive species in the United States is “an alien species whose introduction does or is likely to cause economic or environmental harm or harm to human health” (Zielinski). The International Union for Conservation of Nature, IUCN, defines an invasive species as “animals, plants or other organisms introduced by man into places out of their natural range of distribution, where they become established and disperse, generating a negative impact on the local ecosystem and species” (Zielinski). If we recognize that the human race is an invasive species then we can take steps to lessen the places we are at, the damage we do to the environment, and the damage we do to other species.

Their findings contributed to a further explanation of the definition of an invasive species. It was concluded that invasive species are detrimental to the environment that they are invading. Jackson (2015) mentioned that negative relationships among invaders are a particular concern since it is possible that both of the invasive species would need to be controlled in order for an area to rebound after invasion. Hoopes et al. (2013) concluded that native species on island refuges are more likely to be come extinct during an invasion compared to those of mainland refuges. These results also help to confirm the importance of understanding invasive species from a conservation point of view since invasive species are a major threat to native populations in their
Invasive species as a whole have become a nuisance to many habitats and ecosystems around the world. What defines an invasive species is the following. It must be a species that is foreign to the habitat it resides in, have no natural predators which allow it to reproduce in such a rapid manner, and out compete native animals of food and shelter (Rosenthal 2011). These characteristics are what create such high populations of these invasive species in various habitats around the globe.

Invasive species, (also known as invasive alien species or simply alien species) are defined as any organism (plant, animal, pathogen, or other living thing) that is alien (non-native) to an ecosystem, which can cause adverse economical, ecological, or health effects to native species and/or humans. The roots of these problems all stem from the massive negative ecological impact these organisms are having on the environment (CBD, 2009). For all animal extinctions where the cause is known since the 1600’s, invasive alien species have been a contributing factor 40% of the time (CBD, 2006); the second most contributing factor to extinctions after loss of habitat (GC, 2013). By eliminating native species through competition for resources, predation, and transmittal of disease, invasive species continue to reduce biodiversity in almost all ecosystems around the world (CBD, 2009). In the future, this problem may worsen, and if no action is taken, could lead to a cascading ecological problem so large that whole communities or even ecosystems could collapse.
