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.
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 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 ...
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 ...

Biodiversity hotspots are chiefly tropical regions that feature high concentrations of endemic species and, when all hotspots are combined, may contain over half of the world's terrestrial species. [6] These hotspots are suffering from habitat loss and destruction.
The forests contained the characteristics of high levels of plant endemism and loss of habitats. Myers went on to add eight more hotspots by 1990. Myers went on to add eight more hotspots by 1990. The Conservation International reassessed Myers definition of a hotspot and by 1999 criteria for a hotspot developed to be used globally.
