According to Google Scholar, this paper has over 2500 citations. Even though it was published less than a decade ago, already Myers and colleagues’ ‘hotspots’ concept has become the classic lexicon for, as they defined it, areas with high species endemism and degradation by humans. In other words, these are places on the planet (originally only terrestrial, but the concept has been extended to the marine realm) where at the current rates of habitat loss, exploitation, etc., we stand to lose far more irreplaceable species. The concept has been criticised for various incapacities to account for all types of threats – indeed, many other prioritisation criteria have been proposed (assessed nicely by Brooks et al. 2006 and Orme et al. 2005), but it’s the general idea proposed by Myers and colleagues that has set the conservation policy stage for most countries. One little gripe here – although the concept ostensibly means areas of high endemic species richness AND associated threat, people often take the term ‘hotspot’ to mean just a place with lots of species. Not so. Ah, the intangible concept of biodiversity!
