B. da Fonseca & Jennifer Kent Biodiversity hotspots for conservation priorities Nature403, 853-858 (24 February 2000) | doi:10.1038/35002501 Conservationists are far from able to assist all species under threat, if only for lack of funding. This places a premium on priorities: how can we support the most species at the least cost? One way is to identify 'biodiversity hotspots' where exceptional concentrations of endemic species are undergoing exceptional loss of habitat. As many as 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 land surface of the Earth. Meyers et al.
