The sweeping hemorrhage of species across the planet continues to rattle scientists and conservationists. A recent report from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services revealed that a million species or more could go extinct.
But squaring that global trend with what’s happening at local levels has been difficult. At this level, research shows that the sheer number of species in many spots are holding steady or even going up. That’s led some scientists to believe that species richness, an oft-used measure of biodiversity that tabulates the number of species living in a given area, provides an incomplete understanding of how life on Earth is changing.
