Biology Moreton Bay Ecosystem and St Hellena Bay

Question: Discuss about theBiologyfor Moreton Bay Ecosystem and St Hellena Bay. Answer: Introduction Moreton Bay ecosystem is a rich habitat full of various species that cohabit together to form close relationship. They interact through two factors which include biotic and a biotic variable. In assessing these components the following tools and equipments can be used; techniques for differentiating the organism are done through different keys and field guides notes, utilization of sampling techniques such as underwater video cameras, gliders and sediment grabbers. Methods likely to be beneficial include measurement of data in the ecosystem i.e salinity levels, temperature and lighting exposure. Moreton Bay aquatic system is a natural environment where it is rich in marine habitat, plants and a variety of animals. The extended cover of mangroves is beneficial for birds shelter fish and other wild life animals, the habitat which supports rich variety of fauna and flora. The human contact is characterized by an ideal location for the human impact and cultural initiatives from the neighboring countries. Moreton Bay has a divers system of rich habitat and iconic species, the human population is slowly encroaching and it is a cause for alarm for the impacts which are currently, (Pantus Denninson, 2005). The biotic factors in the Moreton Bay ecology include the living organisms which exist in the ecosystem. It houses approximately 757 species combined of plants and animals. These factors coexist mutually in this intricate ecosystem and all living through creation of symbiotic relationship. The presence of bacteria in the bay plays a crucial role as biotic factor. They occur naturally and majorly found in the sewage pipes, they leave deposits in waterways , and leave sewage smell and effect on water, it has been investigated to causes no harm to the people or animal health. This rich ecosystem forms a close relationship with the fauna and flora through initiatives such as bird watching and planting of the indigenous flora in the ecosystem to create a sustenance relationship, (Hewson et al., 2001). Abiotic factors are those components of non living organisms like soils, weather and geographical positioning which have an impact on the environment, depending on the degree of severity. In Moreton Bay Region, sulfate soils which are in the low coastal areas have been found to have an impact on the soil. They form reactions with the oxygen and cause toxicity and acidity in the air. The effects of the soil on the environment are so broad and harm the environment; it affects the ecology through the killing of fish or causing diseases. The soils have been found to affect the flora and fauna and cause infrastructural damage which facilitates erosion. The mangroves cover is decreased and the animals are likely to fall on the same pattern as they depend on the food produced by the same affected soil components. Lack of food will lead to decrease in numbers in the population of creatures. Acid sulfates cane be harmful to the eyesights causing irritation and dermatitis to both human and ani mals. The impact on climate are evident, the tidal wave changes might affect the marine species, (Clouston, 2002). The response to any changes is the shift of the animals to safer climatic zones or succumbs to changing shift or change in climate. The geographical position is likely to have positive outcome to the ecosystem of Moreton Bay, it is strategically placed in between tropical and temperate waters, and this conditions allows the inhabitation of variety of fauna and flora thus providing a balanced and delicate marine ecosystem. Ways of Improving the Ecosystem Ways of improving the ecosystem at St Helena and Moreton Bay, include expansion of the Marine national park as at current state limits the high number of species from more effective interactions or alternatively to remove the Marine National park zone from the surrounding of St Helena zone. Another option is by creating a Marine National park around the Green island area. Choice of appropriate fishery management tools need to be deployed to manage the fish at the zone., (Van De Geer et al., 2013).The interaction created by the bacteria with water has made the resort to have regular checking to ensure the water is safe for human consumption, (Bunn et al., 2007).
