1 . you Problem Statement
Over a century in the past the hippo seal inhabitants on Macquarie Island survived a period of severe over-harvesting. The practice of hunting seals for food, olive oil and skin had a popular in the market and was typically carried out by Sydney based bande (Bradshaw ou al, 2003). During the early 1900's Macquarie Island was declared a nature reserve and the hunting of closes came to a halt. After cessation of sealing, the people of the elefant seal elevated but continues to be recovering. Through the years, a distinctive decline in the population has become observed and has now been listed being a nationally susceptible species. The species at this point face various potential threats; these include waste debris and pollution from boats, local climate change and oceanographic change and human-related threats such as disturbance with tourism, interaction with fisheries, research or perhaps interference. This kind of report will certainly investigate the results that human activity has on the elephant seal off and assessment the conservation status that will foster a safe and lasting environment for the elephant seal. 1 ) 2 Reason
This task was selected because it is presumed that Macquarie Island isn't only a small nevertheless magnificent refuge, but is likewise one of Australia's truly wonderful island hideaways for our marine mammals. Nestled in the midst of the The southern part of Ocean, it is a protected backwoods that provides exceptional habitats for migratory types and offers an abundance of wildlife. The elephant seal was picked for this report because after extensive analysis was carried out on Macquarie Island and its particular inhabitants, it was found that the elephant seal was the simply mammal on the island that was decreasing in numbers yearly. It is presumed that one of the reasons for this decline is caused by human activity, for that reason making human beings partly responsible for the environment in which they live. It is important to review the different dangers that individuals may create on the mammal and to check out the current solutions that may already be in place to aid the mammal and their environment. 1 . three or more Research Queries
1) What is the history of sealing? And has securing in the past damaged the current drop in the population of the mammal? 2) Exactly what the home requirements to get the elephant seal, i actually. e. their access to area and their foodstuff source? And can lack of food source and access to terrain be affecting the population of the elephant seal off? 3) What sorts of human activity will be contributing to the decline in population with the Macquarie Area elephant seal?
4) What conservation tactics have been implemented to ensure a safe and eco friendly environment pertaining to the hippo seal? installment payments on your 0 Method
In order to commence the research just for this report, a mind map was created to support begin the researching method (See Appendix A). To aid create your brain map an initial web based search was conducted using the Curtin University catalogue and Yahoo Scholar. After narrowing over the initial target, the mind map was then broken down into a few key questions that were then looked into through regular research and focusing on largely scientific content articles and studies. A main concern for the research for this survey was getting articles on the internet which were not going to price any money as many of the articles or blog posts available essential a paid out subscription. To overcome this kind of, reference catalogs from the community library had been sourced and most of the articles on the net were found in the books. Also a beneficial collaborate period that mentioned the Boolean search terms aided in reducing search results on Google Scholar and Curtin University or college library. a few. 0 Discussion posts and Results
