This recent article in the American Naturalist has taken a second look at some of the famously inflated species estimates, some going high as 100 million (Erwin, 1988). Estimates conducted by the authors indicate that projections above 30 million have probabilities of <0.00001. Their estimated range is more likely to be between 2.5 a . . . → Darllen Mwy: Estimates of Global Species Diversity
