A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitation. [1][2] Norman Myers wrote about the concept in two articles in The Environmentalist in 1988 [3] and 1990, [4] after which the concept was revised following thorough analysis by Myers and others into "Hotspots: Earth's ...
This is a hotspot approach because the priority is set to target species level concerns over population level or biomass. [105] [failed verification] Species richness and genetic biodiversity contributes to and engenders ecosystem stability, ecosystem processes, evolutionary adaptability, and biomass. [110]
The California Floristic Province is a world biodiversity hotspot as defined by Conservation International, due to an unusually high concentration of endemic plants: approximately 8,000 plant species in the geographic region, and over 3,400 taxa limited to the CFP proper, as well as having lost over 70% of its primary vegetation.
In-situ conservation. In situ conservation is the on-site conservation or the conservation of genetic resources in natural populations of plant or animal species, such as forest genetic resources in natural populations of tree species. [1] This process protects the inhabitants and ensures the sustainability of the environment and ecosystem.
Biodiversity is commonly measured in terms of taxonomic richness of a geographic area over a time interval. In order to calculate biodiversity, species evenness, species richness, and species diversity are to be obtained first. Species evenness[ 181 ] is the relative number of individuals of each species in a given area.
The 20 current like-minded megadiverse countries. On 18 February 2002, the Ministers in charge of the Environment and the Delegates of Brazil, China, Colombia, Costa Rica, India, Indonesia, Kenya, Mexico, Peru, the Philippines, South Africa and Venezuela assembled in Cancún, Mexico. These countries declared to set up a Group of Like-Minded ...
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 ...
Sundaland, and in particular Borneo, has been an evolutionary hotspot for biodiversity since the early Miocene due to repeated immigration and vicariance events. [3] The modern islands of Borneo, Java, and Sumatra have served as refugia for the flora and fauna of Sundaland during multiple glacial periods in the last million years, and are ...
