Effect of Elephant Ear on Growth of Water Tupelo Research Question: How does the growth of the Invasive Species Colocasia escuelenta (Elephant Ear) affect the growth of Water Tupelo (Nyssa aquatica) in Bluebonnet Swamp? Variables: Independent: Presence of Invasive Species Colocasia escuelenta Dependent: Presence of Water Tupelo (Nyssa aquatica) Background: Colocasia escuelenta is an invasive species primarily present in wetlands, swamps, and along shorelines. This species is typically grown for aesthetic purposes, but has spread to southern wetlands. In these wetlands, it spreads densely in clumps and blocks sunlight and takes nutrients from other native species (Capital Area Plant Society). The elephant ear are characterized by their large leaves that block sunlight from …show more content…

I will wear gloves and cover my whole body to prevent interaction with potentially harmful elements of the environment. I will also be very careful to touch as little as possible in the environment so as not to disturb the wildlife. Hypotheses: If Colocasia escuelenta is present, then Nyssa aquatica will not be, because Colocasia escuelenta is an invasive species that will likely dimish the presence of native species such as Nyssa aquatica. Therefore, the two species will have a negative association. Null: There is no association between the species Colocasia escuelenta and Nyssa aquatic. Alternate: There is an association between the species Colocasia escuelenta and Nyssa aquatic. Methodology: Sample Size: 100 quadrat samples were taken at random in Bluebonnet Swamp. This area was chosen due to its humid climate and it’s wetlands. Data Collection 1. Create a data table like so: Colocasia escuelenta present Colocasia escuelenta absent Nyssa aquatica present Nyssa aquatic absent 2. Place quadrat in a random position within the boundaries of the

    Did you know that you happen to be surrounded by invasive species? These species are animals that come into areas they do not belong in. The articles, “Invaders among Us,” and “Invader Alert,” show this. They harm the environment, cost tons of money in damage and extermination, and they have to be prevented.

    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.

    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).

  • Invasive Species: Eurasian Milfoil

    970 Words  | 2 Pages

    Invasive species are organisms that harm a new environment that they are not native to. Many invasive species like Eurasian milfoil are easily able to reproduce and can do so fast. Due to this, the limited space in a body of water or area of land is quickly taken over by the invasive species so other native plants face the risk of death or even extinction. Overall, these invasive species can do great harm to an ecosystem or an economy, causing problems that are destructive to numerous organisms.

  • The Truth About Invasive Species By Alan Burdick

    960 Words  | 2 Pages

    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.

  • Essay On Elephantiasis

    332 Words  | 1 Pages

    Symptoms of elephantiasis are enlargement and swelling of a part of the body due to the blockage of the lymphatic nodes. The lymphatic system is not able to take out the extra fluid of the body which causes an accumulation of body fluid. The arms and legs are the most affected areas in the body. It can swell to more than three times of its normal shape. Affected areas will have malformed shapes; skin and tissue will become thick and appear to look like an elephant’s leg. The skin of the affected areas becomes extremely dry, thickened (hyperkeratosis), and discolored. Other symptoms may include Fever, chills, and a feeling of sickness. Elephantiasis may affect the male and female external genital area. Some male suffer from enlargement of the scrotum, in some cases scrotum can become abnormally enlarged and can weigh over 100 lb. The penis may be hidden under the skin. In some women the external area of the genitalia will appear thickened and ulcerated rough skin may develop. The breasts may become enlarged. Infected individuals are susceptible to bacterial and fungal due to the damage of the lymphatic system. Infections may become worsen due to the lack of immunity caused by a damaged lymphatic system. People affected by this disease may experience severe pain and a burning

    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 humans are an invasive species. Before people debate 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 outside their natural range of distribution, where they become established and disperse, generating a negative impact on the local ecosystem and species” (Zielinski).

    Elephants should not be killed because they are one of the main reasons that people visit the foreign land of Africa. Africa is incredibly hot and is not the most intriguing place to go on your vacation. If there were no elephants the amount of tourists would significantly decrease. Twenty eight percent of all tourist come to see the elephants. In the movie “Ivory Wars” the narrator says “ One of the few attractions for tourists is the African elephants that run wild and free across the vast plains of the continent of Africa.” When the amount of tourists decrease so does the money that they pay to see the elephants at a safari. Africa is obviously does not have the strongest economy to begin with and without the elephants to bring in tourists the continent of Africa will fall apart. Elephants are exotic and amazing to see, and without them would there really be a reason to visit Africa?

  • Essay On Invasive Species

    1245 Words  | 3 Pages

    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.

  • Habitat Destruction

    Introducing exotic species has been a highly debated issue. Why should we bring another animal or plant into a region to eradicate another species? That’s the question that people have been asking for ages. Of course, there are positives to bringing in another species, but many times, there are just as many negatives. Also, these species can be introduced accidentally or intentionally. The new organism may cause no obvious problems and eventually, it will be considered “native” to the area. For example, corals are “perhaps the oldest animals on the planet, and these long-lived corals have evolved in one of the Earth’s most stable environments” (Eichenberg, p.2). If a new type of fish were to be put into the ecosystem with the corals, the coral would be affected. First, the fish might eat the coral. Second, they could use the coral for shelter, and possibly damaging it that way. Third, the fish could bring predators that might also eat the coral. Introducing an exotic species has the “rippling affect” of dropping a stone into a pool of water. Everything outside the epicenter is affected. A study was done at Cornell University, and they estimated that $120 billion per year are spent fixing the problems caused by exotic species” (Chiras, p.
