What is the importance of hotspots of biodiversity?

These areas that are particularly important for biodiversity conservation are called biodiversity hotspots. Two things are crucial when determining that a place is a biodiversity hotspot: (i) the number of different species there; and (ii) whether species in that area are endangered or currently being destroyed.

How are hotspots formed?

A hot spot is a region deep within the Earth’s mantle from which heat rises through the process of convection. This heat facilitates the melting of rock. The melted rock, known as magma, often pushes through cracks in the crust to form volcanoes. … Instead it occurs at abnormally hot centers known as mantle plumes.

Where are the hotspots located?

Most of these are located under plate interiors (for example, the African Plate), but some occur near diverging plate boundaries. Some are concentrated near the mid-oceanic ridge system, such as beneath Iceland, the Azores, and the Galapagos Islands. A few hotspots are thought to exist below the North American Plate.
