Environmental Impact Of The Asian Mongoose On The Hawaiian Islands

Improved Essays
Abstract

This research paper looks at the impact of the Asian Mongoose on the Hawaiian Islands, and how their existence has put the Hawaiian Islands in a cataclysmic downward spiral within some aspects of their ecosystem. The Asian mongoose has done more than just interfere with the biological stages of the islands it has also been a major hindrance to the economy. The introduction of the Asian mongoose to Hawaii could very well eliminate certain species of birds along the islands. The Asian mongoose was suggested to the sugar farmers of Hawaii from Jamaican sugar cane farmers to control the rats that lived in the fields. This turned out to be a disastrous idea. This release of the mongoose happened in or about the 1880’s and has been plaguing

Who would have realized that the single release could have resulted in such a huge turn of events? The ecological burden introduced to the islands of Hawaii spans well beyond the sugar canes fields of the big island of Hawaii. All throughout Hawaii there are signs of invasion, especially when it comes to the avian population. A record number of the bird species has become critically close to extinction. To include the following birds: “the ne-ne or Hawaiian goose (Branta sandvicensis), the Alala or Hawaiian crow (Corvus Hawaiiensis), the Koloa or Hawaiian duck (Anas wyvilliana), the alae ke‘oke‘o or Hawaiian coot (Fulica alai), the ae‘o or Hawaiian stilt (Himantopus mexicanus knudseni), the alae ‘ula or Hawaiian gallinule (Gallinula chloropus sandvicensis), the ‘ua‘u or Hawaiian petrel (Pterodroma sandwichensis), and the ‘a‘o or Newell shearwater (Puffinus auricularis newelli).” (Hayes, Conant). These are just from the bird population! This just proves that the invasiveness of a single species can totally change how the ecosystem can function. Many other species have been affected by the Asian Mongoose, reptiles for instance have seen a dramatic decline in their reproduction. Today, many mongooses have turned to eating the eggs of reptiles due to the lack of the bird population. This has made the sea turtle population start to see a lowering in reproduction and new birth

    Emma Marris presents us with a new way of viewing nature in the first chapter of her book, “Rambunctious Garden”. She explains that the definition of nature depicted in our “glossy magazines” describing a place “somewhere distant, wild and free” is incorrect, as it “blinds us” from the truth (Marris 1). Marris argues that we must adjust this definition to also include the nature found in “the bees whizzing down Fifth Avenue in Manhattan” and “the butterfly bushes that grow alongside the urban river” as well as the nature found in “managed national parks” (Marris 2). She uses experiences gained during her time spent in the forests of Hawaii and in Australia’s Scotia Sanctuary as evidence to support her argument. Marris also makes the point…

    They don’t have very much competition because they aren’t very picky in their eating habits. They also aren’t in a fight for space (unless you would count us or non native species). They mainly eat fish, smaller birds, bugs, and mice. One of the kinds of birds that they used to eat is the Hawaiian Crow which is now Extinct in the wild. The reason they are near threatened is because people are shooting them illegally, hitting them with their vehicles, and we are taking up their habitat with urban…

Upon their introduction there was a noticeable decline in native vertebrates such as the goanna, northern quoll and freshwater crocodile due to their vulnerability to the cane toad’s poison. This is decreasing the biodiversity amongst the ecosystems as these native species are decreasing in population and are in danger of extinction. This is contrasted with some…

    Edward Hoagland is an animal lover at heart, saying that he has owned “dogs, cats, turtles, snakes, alligators, pigeons, possums, goats” while he was in his home state of Connecticut (Stuttering Foundation). He writes about animals and their conservations often. He has many works, 60 years’ worth, of conservation of animals fueled by this relentless desire to write for animals who cannot write for themselves (Stuttering Foundation). An example of these animals that need a voice are turtles. Turtles are a less familiar species that are easily overlooked by humans.…

    My endangered species is called the Bog Turtle. The Latin name for the bog turtle is the Glyptemys Muhlenberg.

    Florida Invasive Species

    Introduction Southwest Florida's ecosystem consists of warm temperate waters and a subtropical climate that attracts the majority of the generalist species. Generalist species are species that can adapt to a variety of locations without needing certain foods to eat or certain climates to survive in. Attracting generalist species that do not belong a part of Southwest Florida's ecosystem concludes in an unbalanced environmental system. My interest in this topic was the certitude that if we continue to surmise that this issue will not affect us, it will cease in an extremely negative way. It is crucial to inflate the effects invasive species have on our ecosystem to prevent any more harm to the environment.…

    Think back to the last vacation you had overseas and how many American companies you may have seen in that foreign country. Whether it was McDonalds or a JW Marriott, western culture is an overarching presence in Latin America. Not only can it potentially interfere with the current culture of the country, it also exploits the land and resources in the area. In Through the Arc of the Rainforest, Yamashita discusses the globalization process through overarching American corporations westernizing Southern America. Because of this, nature is exploited and not left to be natural.…
