Document Summary
Area of tropical rainforest the size of fifteen city blocks may contain over a thousand different. Panamanian rainforest, just one of these tree species can yield as many as 945 different species of tree species beetles alone. Astonishing diversity also extends to aquatic environments africa"s lake malawi is home to over. 500 species of fish, belong to a single genus. Speciation the evolutionary process by which new species are formed, clearly responsible for the ultimate generation of species diversity over geologic time. How different species coexist (co-occur in the same location for many generations) is a long- standing and not fully resolved question for ecologist. Competitive exclusion principle states that two species competing for the same resource cannot coexist. The species that is better at gaining the limiting resource will eventually eliminate the inferior competitor. Simple prediction of the competitive exclusion principle is schematically portrayed in figure 2a.
