“Invasive species are a rapidly growing problem, and in many areas, they are the second-most-important cause of species declines” (Perry & Vice, 2009, p. 993). Often times, the invasive problem is by accident due to transportation of the species, but at times is intentional. This paper will review the history of the Brown Tree Snake as an invasive species, a species description of the Brown Tree Snake, and the impact this species has had on Guam. Potential ways to resolve and control the ecological and economic impacts of the Brown Tree Snake on Guam and efforts to prevent new invasions by this species on other Pacific islands

than usually destroy the environment they are introduced to. Take the cane toad for example; this is an invasive species problem that is currently occurring in the United States. The cane toad (Rhinella marina), is a species that is native to South America, Central America, Mexico, and southwestern Texas. The cane toad began to become introduced in Florida, Hawaii, and even Louisiana. Originally, they were let out around sugar cane plantations in order to eliminate pests that ate the cane. Eventually they “escaped” and people began to keep them as pets and in their backyards. The cane toad preys on and can sometimes compete with native species due to having similar niches. The cane toad also secretes a toxic chemical from its skin, which is extremely poisonous for common household pets, including dogs, cats and birds (Hardman).

In the past we have tried to contain these Cane Toads by setting up traps in the dry-seson however many blue tongue lizard got caught in them. They also tried to set up fences around areas that only have 1 or 2 freshwater lakes in them so that the babies cannot walk away from the area. This worked but we cannot simply fence up all the water sources in the top half of Australia. But I think we should create a poison on the cane toads. Because the other thing that eats Cane Toads is Cane Toads; therefore if we create a poisson on them we are able to get rid of many toads. The first step in creating this plan would be to make the poission. Secondly we would give the poison in a syringe to every homeowner in Northern Queensland so that they can

Invasive species are a potential critical problem. They can influence the environment completely; anything from individual species to entire ecosystems. The brown tree snake was at first located in Indonesia and New Guinea, but the brown tree snake became an invasive species to Guam by coincidence (3). Because the Brown tree snake is very capable to hide in confined spaces it is believed that they were distributed to Guam by U.S military ships during their war against Japan (5). The brown tree snake can be easily distinguished by its brown, greenish colour, rear fangs and a large, almost disproportioned, head compared to its body (5).

There are many invasive species that populate Florida. An invasive species is defined as a plant, animal, or fungus that has come to occupy a location aside from its native grounds. Often times, because Florida is not their homeland, these animals play a negative part in the ecosystem. Because of this, the citizens affected are often forced to seek means of removing these animals to eliminate their negative effects. The Burmese Python, the Green Iguana, and the Wild Boar are just a few examples of some of the invasive species that can be found in Florida.

Over one hundred million years of existence, capable of traveling through the oceans of the world. One creature so magnificent that it is able to live up to 70 years old and weigh between 200 to 500 pounds. This creature is the majestic Hawaiian green sea turtle. Although they are found throughout the world, Hawaiian green sea turtles are distinctly different from other green sea turtles (NOAA Fisheries par. 4). They travel to the Northwestern Hawaiian Islands to nest and then travel to the main Hawaiian Islands to feed. Such a unique creature is very important to the Hawaiian Islands. Hawaiian green sea turtles play an important role in the ecosystem, the economy, the culture, and the

Firstly, the author states the one way to prevent the spread of the Cane toad would be to build a national fence that blocks the advance of the toads will prevent them from moving into those parts of Australia, on the contrary, the professor believes the national fence is not a useful way to block of this amphibian because some young ones and the eggs of these animals

An invasive species in my state, the state of Louisiana, would be the Nutria, also known as Coypu. Nutria are a beaver-like rodent, originating from South America and popular for their fur. They are semi-aquatic with webbed feet and are known to be strong swimmers that can stay submerged underwater for up to five minutes. They are commonly found in the wetlands or burrowing in riverbanks. They are omnivores, their diet consisting of mussels, snails, and roots. They are commonly known as the river rat while they are scientifically known as Myocastor coypus.

Coccinia grandis is a common invasive plant species found on Hawaii (KISC, 2015). This vine-like plant displays broad, flat leaves with star-shaped white flowers, and is characterized by chili-like red fruits (Fox, 2008, p.D8). According to Fox, C. grandis (also referred to as 'Ivy Gourd') is native to parts of Southeast Asia, India, and Africa, and it is likely that this hardy (and hard to eradicate) plant found its way to the Hawaiian islands as a hidden passenger on immigrants from these areas. It is well established that C. grandis is a harmful invasive species posing a threat to native Hawaiian plants and ecosystems in direct and indirect ways. Despite the plant's negative effects on Hawaiian plants, however, research has shown that C.

What is a Hawaiian rainforest without its Hawaiian native plants. Our island of Hawaii has took a rough turn and the amount of our Hawaiian native wildlife has decreased drastically. This new change is caused by the indigenous beautiful, yet deadly, Kahili Ginger. Individuals who support this claim are the Hawaii Volcanoes National apart Recreational People. They believe the Kahili Ginger plays a huge roll in the decline of native wildlife. The Kahili ginger is a huge problem in Hawaii primarily because it grows so rapidly, and displaces native mosses, ferns, and other shrubs.

E. coqui reproduce in their native range year round, but during wet season is when breeding activity is concentrated. A female E. coqui lay 4-6 clutches of about 28 eggs each and about 16-41 clutches per year. The life cycle for the E. coqui start in a larval form that leads in a froglet within the egg. The next stage make this frog unique as it bypasses the tadpole stage in development, this is called free-living. The E. coqui internal fertilizes and, like other eleutherodactylids, the fertilized eggs never pass through a free-living larval (tadpole) stage. This particular stage is key to the success in the E. coqui survival in different habitats. It allows for the eggs to be

Overall, they conducted an experiment over an invasive species in Florida. Invasive species can negatively affect communities and ecosystems on a world-wide scale. According to the authors, “Most reptiles are predators that, as ectotherms, can direct large proportions of assimilated energy to growth, storage, and reproduction, often allowing them to persist at high densities and pose major risks to native wildlife.” Once these predators take root in a new environment, it may take a while before people realize any decline in native species. The invasive species this study focuses on is the Burmese Python which can grow up to 55 meters. The Burmese Python originally came from Asia. Though recently, they were introduced to Florida, specifically

Frogs has many ways in which they protect themselves from their predators. There are some frogs that contain poison to defend themselves. Frog release a posion toxics when animals try to eat them. The predators can't eat these frogs due to the posion the frog gives off. The

Since an invasive species can be any kind of newly introduced living organism then it would be hard to determine what risk there would be from the introduction and what they would result in since, “Approximately 42% of Threatened or Endangered species are at risk primarily due to invasive species” (Source A). This shows that the introduction between these species have either not been thought out well or nothing has been done to prevent these threats. Since the protection of the native specie and the ability of the non native specie to adapt to the new environment is a crucial factor for a good encounter, the results must first be calculated as accurate as possible in order for the government to base the decision upon because the non native species will endanger the native specie if it becomes more dominant. Therefore, the habitat and food cycle of the native species must also be studied in order to prevent any altercations because they are considered one of the most impacted areas when the defence system of the native species is off. As a result, transferring the non indigenous specie into the habitat of a native specie will only be beneficial if there is balance in their ability to defend themselves from one

The biodiversity effects of non-native invasive species have been described as “immense, insidious and usually irreversible” (Veitch and Clout, 2002). There is significant evidence proving that invasive species can cause severe economic, environmental and ecological damage (Mack et al., 2000). A lot of time and research has been devoted to dividing the world into regions with distinctive habitats and species. Numerous pathways, mostly anthropogenic, are breaking down these realms and facilitating the ecological and biological invasion of non-native species.
