The Nature Conservancy’s Atlas of Global Conservation is a fabulous resource for understanding biological diversity. Scientists have divided up the world into more than 1,000 ecoregions and analyzed how they compare across dozens of measures. I’ve used data from TNC’s atlas to create a slide deck that illustrates patterns in species richness and threats to […]
