It must have at least 1,500 vascular plants as endemics — which is to say, it must have a high percentage of plant life found nowhere else on the planet. A hotspot, in other words, is irreplaceable. It must have 30% or less of its original natural vegetation. In other words, it must be threatened.
Which of the following is the characteristics of hotspot biodiversity?
To qualify as a biodiversity hotspot on Myers 2000 edition of the hotspot-map, a region must meet two strict criteria: it must contain at least 0.5% or 1,500 species of vascular plants as endemics, and it has to have lost at least 70% of its primary vegetation. Around the world, 36 areas qualify under this definition.

- It must contain 30% (or less) of its original habitat, i.e. it must be threatened.
What is the hot spot?
Mobile WiFi hotspots
Did you know that you can use your iPhone or many Android smartphones as a WiFi hotspot? By turning on this feature, your phone uses its cellular data to create a WiFi hotspot. You can then connect a computer or other device to this hotspot to access the internet.
What are biodiversity hotspots What is the measure of the biodiversity?

What are hotspots of biodiversity class 12?
Class 12 Biology: A biodiversity hotspot is a biogeographic region that has a significant pool of biodiversity but at the same time it is also threatened with destruction. The British biologist Norman Myers gave the term “biodiversity hotspot” in 1988.
