What are some different types of biological diversity?

There is ecological diversity, species diversity, genetic diversity, and ecosystem diversity.

Usually, when we talk about biological diversity , we mean ecological diversity. Ecological diversity is the number of species within a community.

There is also species diversity, meaning the diversity or variety of species in a defined area. Species diversity incorporates both species richness and how even species abundance is distributed. Tropical forests are high in biodiversity because they have many different types of species. This is perhaps the most common meaning of biodiversity.

Another use of biodiversity refers to the genetic diversity within a species. Cheetahs have low genetic diversity whereas the domestic dog has tremendous diversity. The biodiversity of some species is higher than others.

The last common use of biodiversity is in reference to ecosystem biodiversity. This is the variety of different ecosystems within an area. For example, ecosystem biodiversity on Madagascar is very high.
