Interesting article in Science looking at the role of latitude in extinction and speciation. The authors conclude: ” most efforts have aimed at identifying the geological, climatic, and ecological factors that might have elevated tropical speciation rates, our results suggest that both speciation and extinction vary with latitude and contributed importantly to the latitudinal diversity gradient.” You or your institution will need a subscription to get past the abstract.
