Science Definition Of Biodiversity Hotspot
Biodiversity hotspots are home to unique flora and fauna most of which are endemic to the particular environment.
Science definition of biodiversity hotspot. To qualify as a biodiversity hotspot an area must meet two strict criteria. Earth s biologically richest and most endangered terrestrial. Hotspots were thought to be caused by a narrow stream of hot mantle. In geology a hotspot is a location on the earth s surface that has experienced active volcanism for a long period of time.
The term biodiversity hotspot specifically refers to 25. To qualify as a biodiversity hotspot a region must meet two strict criteria. The concept of biodiversity hotspots was originated by norman myers in two articles in the environmentalist 1988 1 1990 2 revised after thorough analysis by myers and others in hotspots. A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitation.
A biodiversity hotspot is a biogeographic area notable for sustaining significant levels of biological diversity and which is threatened by destructive activities. Norman myers wrote about the concept in two articles in the environmentalist 1988 and 1990 revised after thorough analysis by myers and others hotspots. Biodiversity hotspots make up about 2 3 percent of earth s land surface but 44 percent of the world s plants and 35 percent of land vertebrates live in these regions. Yet biodiversity hotspots are by definition in a conservation crisis.
Most plants in a biodiversity hotspot are endemic meaning they are not found anywhere else on earth. A biodiversity hotspot is a biogeographic region that is both a significant reservoir of biodiversity and is threatened with destruction. Many of the biodiversity hotspots exceed the two criteria. Guarding these regions from further damage is considered environmentally and culturally.
Contain at least 1 500 species of vascular plants found nowhere else on earth known as endemic species. It must have 30 or less of its original natural vegetation in other words it must be threatened. A biodiversity hotspot is a region of the earth that is extremely biologically diverse and also under severe threat due to habitat loss climate change or extensive species loss around 25 sites worldwide are recognized as such hotspots and several organizations have made efforts to protect these sites. The objective of this study was to show how unpublished data in combination with citizen science can be useful for identifying biodiversity hotspot areas using thailand as an example.
Earth s biologically richest and most endangered terrestrial ecoregions and a paper published in. A biodiversity hotspot is a biogeographic region with a significant reservoir of biodiversity that is under threat from humans. Have lost at least 70 percent of its primary native vegetation.
