How can genetic diversity be measured

WebDiversity can be measured by considering species richness, the Shannon index, or Shannon entropy. The data on biodiversity are incomplete or insufficient to provide a complete picture. Nevertheless, the available information helps decision-makers to come up with useful approximations for terrestrial and marine ecosystems.
