What is biodiversity?

Global Biodiversity Outlook 3 – VNR

The most comprehensive report yet compiled on the state of life on our planet based not only on a wide range of scientific studies, but also on 110 national reports, compiled by governments.

What is biodiversity?

From the hot arid deserts of the Sahara, through the lush green rainforests of the Amazon, to the ocean depths and bright corals, our natural world is a marvel of different landscapes, materials, colours and textures.

The land, air and seas of our planet are home to the tiniest insects and the largest animals, which make up a rich tapestry of interconnecting and interdependent forces.

This is life, this is biodiversity.

Biodiversity found on Earth today consists of many millions of distinct biological species. the product of four billion years of evolution .

However, the word “Biodiversity” is relatively new, and is thought to have first been coined as a contraction of the term "biological

diversity" in 1985 and then popularized by a number of authors. (Nematology: advances and perspectives, Volume 1By Z. X. Chen, S. Y. Chen, Donald Ward Dickson p439)

Biodiversity is the variety of life on Earth. it includes all organisms, species, and populations; the genetic variation among these; and their complex assemblages of communities and ecosystems.

It also refers to the interrelatedness of genes. species. and ecosystems and in turn, their interactions with the environment.

Three levels of biodiversity are commonly discussed—genetic, species, and ecosystem diversity.

     1. Genetic diversity is all the different genes contained in all the living species including individual plants, animals, fungi, and microorganisms.

     2. Species diversity is all the different species, as well as the differences within and between different species.

     3. Ecosystem diversity is all the different habitats, biological communities and ecological processes, as well as variation within individual ecosystems.
