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 1,500 species of vascular plants (more than 0.5% of the world's total) as endemics, and it has to have lost at least 70% of its primary vegetation. [6]
The region was designated a biodiversity hotspot by Conservation International. Geography. The forests extend in a narrow band along the coast of the Indian ...
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 ]
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.
Tumbes-Chocó-Magdalena is a biodiversity hotspot, which includes the tropical moist forests and tropical dry forests of the Pacific coast of South America and the Galapagos Islands. The region extends from easternmost Panama to the lower Magdalena Valley of Colombia, and along the Pacific coast of Colombia and Ecuador to the northwestern ...
Biodiversity hotspots and coldspots are a way of recognizing that the spatial concentration of genes, species, and ecosystems is not uniformly distributed on the Earth's surface. [100] For example, "... 44% of all species of vascular plants and 35% of all species in four vertebrate groups are confined to 25 hotspots comprising only 1.4% of the ...
The Conservation International reassessed Myers definition of a hotspot and by 1999 criteria for a hotspot developed to be used globally. A hotspot needs 1,500 endemic vascular plant species and a loss of at least 30 percent of its original land. [2] [3] [4] With these criteria, 25 hotspots were identified in 1999 and published in the journal ...
The transition to the Sundaland Hotspot in the south occurs on the Thai-Malay Peninsula, the boundary between the two hotspots is represented by the Kangar-Pattani Line, which cuts across the Thailand-Malaysia border, though some analyses indicate that the phytogeographical and zoogeographical transition between the Sundaland and Indo-Burma ...
