Higher plant diversity does not appear to have any great effect on soil processes such as decomposition rates, but does affect productivity and enhances the stability of ecosystem processes. Generally speaking, greater species diversity (alpha diversity) leads to greater ecosystem stability. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level. Three main mechanisms are likely to operate in the stabilising effects of biodiversity on ecosystem properties: (1) asynchrony of species' intrinsic responses to environmental fluctuations, (2) differences in the speed at which species respond to perturbations, (3) reduction in the strength of competition. Linking the ecosystem multifunctionality concept and ecosystem stability can transform the perceived effects of diversity on ecological stability and may help to translate this science into policy-relevant information. Even though scientists may use cloning, there’s nothing we can do about it once a species becomes extinct.
