Detailed explanation-1: -Biological hot-spots include the Western Amazon (Colombia, Ecuador, Peru), Madagascar, North and eastern Borneo, Northeastern Australia, West Africa, and the Brazilian Atlantic forrest . All of these areas have high diversity and many are threatened by human activities.
Detailed explanation-2: -Tropical forests are typically biodiversity hotspots and are usually filled with endemic species. The Upper Amazonia/Guyana Shield, the Congo Basin, and the New Guinea/Melanesian Islands have the highest number of endemic terrestrial (land-living) species on Earth [6].
Detailed explanation-3: -It is because tropical regions have a stable ecosystem, suitable weather, and a favourable environment for animals, plants, and other living things to survive.
Detailed explanation-4: -Around the world, 36 areas qualify as hotspots. Their intact habitats represent just 2.5% of Earth’s land surface, but they support more than half of the world’s plant species as endemics-i.e., species found no place else-and nearly 43% of bird, mammal, reptile and amphibian species as endemics.
