Isopods have the highest species diversity in natural habitats such as wetlands and natural forests. The species richness in these habitats is directly correlated to the presence of both the species typical to natural areas and the synanthropic ones. The high diversity in these areas can be contributed to terrestrial isopods showing a preference for moist environments with large amounts of organic matter available (FERENTI et al 2013). The terrestrial isopod is known as a crustacean and they show a preference in these moist environments mainly because the have gills for breathing. Since they have gills they must stay in areas that tend to have more moisture (Ayari et al 2016). Environments similar to natural rain forests and wetlands tent to have a more acidic soils. These acidic soils are rich in metals that are nutritious for the isopods. In these moist environment isopods can find soils and leaves that contain large quantities of cadmium and many other heavy metals. They consume these heavy metals and in turn effectively clean up the soil (Mann et al 2005).
Terrestrial isopods tend to inhabit moist acidic environments but what would happen if the isopod could choose its preferred habitat (Mann et al 2005). Specifically, what would an isopod choose when given the option of a neutral PH, an acidic PH, or a basic PH. The reasoning for this experiment sets out to gather supporting evidence as to which environment an isopod would favor when given an immediate choice. What was tested was whether terrestrial isopods would show a preference when given the choice between the following variables; RO water and RO water (the negative control), an acidic solution and RO water (the positive control), an acidic solution against a basic solut...

...came when the isopods were given the option between a basic solution and acid solution. In this instance and equal distribution was also found (Figure 4).
According to the data collected from this experiment and the experiment the isopods should have leaned toward the acidic environment. Instead the data collected resulted in an equal split between the acid and the base. This is most likely due to major design flaw in that not enough isopods were tested during each trial. This lead the numbers to be to close to each other and not allow for a deviation to occur. This is why the numbers resembled random chance and not the acid favoring we desired. In future investigations a simple way to correct this problem would be to add more isopods per trail. Running a trial with upwards of around a 100 isopods would yield greater results and allow the data to be more consistent.

Essay on Protecting And Conserving Natural Habitats And Ecosystems

- Over the last two decades there has been a heightened emphasis on protecting and conserving natural habitats and ecosystems in order to protect the environment (Saayman et al., 2015). This has resulted in an increased desire to participate in nature-based and wildlife viewing activities before it is too late, and a corresponding rise in popularity of ecotourism (Tonder et al., 2013). Today, more so than ever before, there has been a significant focus around ensuring that tourism development is biologically sustainable (Kruger and Saayman, 2013, cited in Saayman et al., 2015)....   [tags: Tourism, Natural environment]

Essay about The Endangered Species Act ( Esa )

- In the year 1973, the Endangered Species Act (ESA) was instituted in order to bring attention to the issue of species that are in danger of extinction as well as to provide conservation of species that are endangered or threatened. Currently, there are around 2,245 species that the Endangered Species Act lists as either endangered or threatened throughout the world, many of which are found in the United States ecosystems and a handful that are only found in foreign ecosystems (Ehrlich 12). Because of the considerable number of endangered species, people should be aware of endangered species and help to protect these creatures society, as their unnatural extinction due to our actions and negl...   [tags: Extinction, Endangered species, Biodiversity]

- Darwinism is a theory developed by Charles Darwin with the help of many others. It states that natural selection is the most common cause of evolution. All species of organisms arise and grow through the natural selection of inherited variations that help increase the individual's ability to survive and reproduce in its environment. 1735 Carolus Linnaeus: He believed that God had created the world in a divine order from the simplest creatures up to human beings.

Animal Species Are Threatened By Extinction Essay

- Have you ever wondered how many plant and animal species are threatened by extinction. In an article of an issue of the Discovery Education magazine it stated “To date 16,928 plant and animal species are believed to be threatened with extinction.” (Extinction Facts) That is an enormous number and with the constant growing and changing world that number will only increase. Based on all the environmental factors placed on animals, the extinction of untamed animals is inevitable but, steps should be taken to preserve the remains of untamed animals so that scientific research can be conducted....   [tags: Extinction, Endangered species, Global warming]

Essay about Biogenic Habitats

- Human-induced alteration of biogenic habitats at the landscape scale is increasing, and directly influencing local diversity and system functioning (Vitousek et al. 1997, Duarte 2002, Lozte et al. 2006 and Airoldi & Beck 2007). Alteration of natural landscapes can result in loss of entire habitats or transition of more complex to less complex habitats, for example shellfish reefs or seagrass beds to mud flats (Short and Wyllie-Echeverria 1996, Hughes et al. 2002, Ruesink et al. 2005, Thrush et al....   [tags: Biodiversity, The Canopy]
