Biodiversity and Biodiversity Indices

The most obvious definition of biodiversity is the variety of species on Earth. Biodiversity or biological diversity refers to the variety of life forms: the different form. This plants, animals and microorganisms, the genes they contain, and the ecosystems they living wealth is the product of hundreds of millions of years of evolutionary history. Biological diversity is usually considered at three different levels: genetic diversity, species diversity and ecosystem diversity.
Genetic diversity refers to the variety of genetic information contained in all of the individual plants, animals and microorganisms. Genetic diversity occurs both within and between distinct populations of the same species, as well as between species in one particular population. New genetic variation is produced in populations of organisms that can reproduce sexually by recombination and in individuals by gene and chromosome mutations.…
