Wellecome!

This space is intended to be useful during this extraordinary course of Environmental Systems and Societies. A subject such as this demands specific and detailed data about how the environment is formed and how it works, besides the most recent and relevant events regarding ecological issues. And what could be better than a blog to have and share all this information. I hope all posts will be useful to create an ESS thinking; also I am looking forward to learn from the comments you leave.

Biodiversity

"Biological diversity" or Biodiversity is the amount of the different species, plants and animals, that can be found within an ecosystem, biome or the entire Earth. 

As time passes by, different biodiversity indices have been created. The completest one might be the Simpsons' one. It covers dominance, diversity and evenness.

Why to measure biodiversity?

It can be a reflect of the health of an ecosystem, because is clear that an ecosystem that has a wide biodiversity have favorable conditions for life to grow, but there are some "healthy" ecosystems with a narrow biodiversity, and that's why not always biodiversity is used to measure this.
As an index, biodiversity can state the natural capital that have certain ecosystem, in terms of species living inside, which is a reflect of the synergy between biotic and abiotic factors which allow a "fertile" and suddenly stable ecosystem. Taking this, biodiversity allow humans to put a value in the natural resources provided by the ecosystem, justifying the measurement of biodiversity as a way to determine "how rich" an ecosystem is.
