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,
