where are many critical biodiversity hotspots located?

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].

Brazil is the Earth's biodiversity champion. Between the Amazon rainforest and Mata Atlantica forest, the woody savana-like cerrado, the massive inland swamp known as the Pantanal, and a range of other terrestrial and aquatic ecosystems, Brazil leads the world in plant and amphibian species counts.

Forests are biodiversity hotspots because they are areas with many different types of species that are under threat from human activity.

Importance. The Western Ghats are known for their high biodiversity and endemism as it is identified as one of the world's eight hot hotspots of biological diversity. It is classified as evergreen forest as it receives as much as 350 inches of rain every year.

In geology, the places known as hotspots or hot spots are volcanic regions thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle. Examples include the Hawaii, Iceland and Yellowstone hotspots.

Biodiversity is important for human wellbeing as it provides food, potential foods, industrial materials and new medicines. Activities that create air and water pollution are reducing biodiversity in many ecosystems.

Biodiversity refers to the number of biological species that exist in a given region. High biodiversity means that a region supports a wide variety of species, while low biodiversity implies that an area supports only a few.

Criterion (x): The enormous size and diversity of the GBR means it is one of the richest and most complex natural ecosystems on earth, and one of the most significant for biodiversity conservation.

It has been shown that biodiversity of an area has a large impact on the ecosystem stability of that area. Areas with high levels of species and genetic diversity are likely to have a more complex ecosystem, with a variety of food webs and biotic interactions.

Biodiversity is important on many levels, from the scale of an ecosystem, to the global scale. ... Biodiversity at this scale is important because it ensures ecosystem stability. With a large number of species present in an ecosystem the extinction of one is less likely to have a major impact on the rest of the system.
