Calculating species extinction rates is a tricky business at the best of times, but a new research paper in Nature suggests the most widely used methods are “fundamentally flawed” and overestimate extinction rates by as much as 160 percent. Paper co-author Stephen Hubbell, a distinguished professor of ecology at UCLA, explained why he believed extinction […]
