Literature review - Essay Example Geologic, fossil and ecological records have provided the evidence for the variable nature of the climate whose occurrence in the past has caused the evolution of various eco systems of the earth (Emmanuel, W.R, Stughart, H.H, Stevenson, M, 1985, p.29-43). The change caused in the precipitation rate which is one of the resultant effects of the climate change is expected to affect the interaction between the checker spot butterfly larvae and its host plant. This reason when coupled with the disturbance of the habitat of the butterfly would aggregate the problem when it is observed in relation with the dispersal ability of the species. The study was taken with the hypothesis that extinctions of two populations of the checkerspot butterfly, Euphydryas editha bayensis, were caused by a combination of habitat loss and regional climate change in the form of increasing variability in precipitation (McLaughlin et.al, 2002). Euphydryas editha bayensis is a beautiful and charismatic butterfly species which is a resident species of Western North America. (Dyke, F.V, 2008,p.128). Taylor, K. E. and Penner, J. E. (1994, pp. 734 – 737) has described the major cause of climate change as man made carbon and other Green House Gas emissions in addition to the natural changes in climate. Several detrimental effects like Sea-level rise, Hurricanes, Diseases, Famines, Desertification and Species loss has been pointed out as the impacts of climate change.(Morris, Julian 1997,p.5-17). Though this study had only general indications towards the impact of climate change on species loss, this indication has been reiterated by a number of literatures which state that climate change would affect the population of animal and plant species. Christina Figueres & Maria Ivanova (2002,p.205) has argued that climate change would affect the major components of our biosphere including air, the ocean, the range of animal and plant species and the climate system itself. A study by J. B. Hughes,

Communication - Essay Example Finally I analyzed how clearly did the two men speak and what effect their clarity had on the overall speech and the message they were trying to convey. By analyzing the two speeches there were number things that I was able to understand. Analyzing the two speeches required me to utilize my observational skills to assess the type of expressions that president Obama and Lt. General David Morrison portrayed while delivering their respective speeches. A speech has little to do with words and has more to do with the manner in which message of the speech is conducted. The manner in which Morrison delivered his speech was firm, whereas Obama’s manner delivered it in a manner that displayed immense sorrow for individuals that had lost their lives. Such gestures are non-verbal gestures that I learned to quickly pick up. Another thing that I learned from analyzing the two speeches understood the reaction or their emotions from the clarity in their voice and how easily it was for them to speak out words of the speech. While working on the article analysis I worked on was to gather information regarding the current method that has been employed by airline companies regarding communication systems being used in emergencies. I initially obtained information of the internet, which required a great deal of research skills. Using the internet I was able to obtain a great deal of information, however a great deal of this information was either irrelevant or was outdated. I filtered the information that was needed and then organized it in a presentable manner. In order to obtain information in a greater depth I discussed the article with a number of individuals that had experience with the field. Before contacting these individuals I developed a set of questions that was directed at obtaining information in much greater detail. I later compiled the answers I got
