Climatic Changes and its Impact on Biodiversity

Seeking explanations for this fascinating question of how animals and plants are distributed in the world has a long history among bio geographers and ecologists. The present distribution pattern of any species on the Earth is affected by a set of historical, climatological, geological and ecological factors, mainly elevation, temperature, precipitation, soil type and vegetation cover. Moreover, habitat suitability and its relevant issues (e.g. micro-climatic conditions) and organism association with its ecological niche, the environmental requirements of species or the impact that the species can have on its environment, have crucial role for providing better insights on dispersal, diversification patterns and speciation mode of different taxa. However, a limited number of studies have been focused on climatic conditions as an important key affecting species presence, their activity and life cycle and different levels of ecological hierarchy.
