The high profile of the biodiversity hotspots approach has resulted in some criticism. Papers such as Kareiva & Marvier (2003) [21] have pointed out that biodiversity hotspots (and many other priority region sets) do not address the concept of cost, [22] and do not consider phylogenetic diversity. [23]
Megadiversity means exhibiting great biodiversity. The main criterion for megadiverse countries is endemism at the level of species, genera and families. A megadiverse country must have at least 5,000 species of endemic plants and must border marine ecosystems.
Biodiversity hotspots across the world Several international organizations focus their conservation work on areas designated as biodiversity hotspots . According to Conservation International , to qualify as a biodiversity hotspot a region must meet two strict criteria:
Tropical regions are hotspots for biodiversity, so conservation efforts are essential to focus on in these places. Many species can be observed and conserved in the tropics. [ 8 ] The tropics receive much attention when it comes to conservation and management due to increased public awareness of the significance of tropical ecosystems and the ...
Maputaland-Pondoland-Albany Hotspot 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 forests extend in a narrow band along the coast of the Indian Ocean, from southern Somalia in the north, through coastal Kenya and Tanzania to the mouth of the Limpopo River in southern Mozambique.
Most of the exponential human population growth worldwide is occurring in or close to biodiversity hotspots. [6] This may explain why human population density accounts for 87.9% of the variation in numbers of threatened species across 114 countries, providing indisputable evidence that people play the largest role in decreasing biodiversity. [18]
This biodiversity hotspot is known for being the home of the Sierran giant sequoia tree and its close relative the coast redwood. [1] In 1996, the Province was designated as a biodiversity hotspot allowing it to join ranks among 33 other areas in the world with many endemic species. To be named a biodiversity hotspot, an area has to contain ...
