14.2 Differences in biodiversity

Different regions on planet Earth have different levels of biodiversity. Different ecosystems are home to different organisms that have adapted to the specific conditions of their ecosystems. Different ecosystems also accomodate different levels of biodiversity. 


Biodiversity hotspots.

Some regions of the planet (such as the island of Madagascar) accomodate exceptionally high levels of biodiversity. These kind of regions are called biodiversity hotspots.

Biodiversity hotspots are mostly found in the tropical and subtropical geographic zones. Many biodiversity hotspots are located in isolated oceanic islands, such as the Galapagos islands and the Hawaii islands. These areas have developed their own, unique species that are not found anywhere else on the planet. Such species are called endemic species.


The islands of Hawaii are one of the biodiversity hotspots of planet Earth.
