A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitation. [1] [2] Norman Myers wrote about the concept in two articles in The Environmentalist in 1988 [3] and 1990, [4] after which the concept was revised following thorough analysis by Myers and others into "Hotspots: Earth's Biologically Richest and Most Endangered ...

Habitat destruction. Map of the world's biodiversity hot spots, all of which are heavily threatened by habitat loss and degradation. Habitat destruction (also termed habitat loss and habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved to elsewhere or ...
Mesoamerica is considered one of many biodiversity hotspots where extinction is a significant threat. [5] This area is the world’s third largest biodiversity hotspot. [1] Some efforts have been made to protect organisms in the region, however, many of these protected sites are “small, fragmented, isolated, or poorly protected”. [4]
Global biodiversity is the measure of biodiversity on planet Earth and is defined as the total variability of life forms. More than 99 percent of all species [ 1 ] that ever lived on Earth are estimated to be extinct. [ 2 ][ 3 ] Estimates on the number of Earth's current species range from 2 million to 1 trillion, but most estimates are around ...
Sundaland[1] (also called Sundaica or the Sundaic region) is a biogeographical region of Southeast Asia corresponding to a larger landmass that was exposed throughout the last 2.6 million years during periods when sea levels were lower. It includes Bali, Borneo, Java, and Sumatra in Indonesia, and their surrounding small islands, as well as the ...
The Maputaland-Pondoland-Albany Hotspot ( MPA) is a biodiversity hotspot, a biogeographic region with significant levels of biodiversity, in Southern Africa. It is situated near the south-eastern coast of Africa, occupying an area between the Great Escarpment and the Indian Ocean. [ 1] The area is named after Maputaland, Pondoland and Albany.
Himalayan high-elevation wetlands are also notable for their biodiversity. [3] The picture seen right is of the national flower of Bhutan Meconopsis gakyidiana, commonly called the blue poppy. This flower was the source of an ecological mystery for nearly a century, due to its misclassification as Meconopsis grandis. In 2017, after three years ...
