Description:

Explain the concept of biodiversity and how it is measured.

Biodiversity exists at three scales: ecosystem diversity, species diversity, and genetic diversity.  Environmental scientists measure species diversity both by the number of species in a particular location (species richness) and by how evenly individuals are distributed among those species (species evenness).  The greater the number of species, and the more even the distribution, the higher the diversity.
