Douglass et al. ( Ecol. Lett. , 11 , 2008, 1) concluded that grazer diversity and predator diversity have an interactive effect on herbivore abundance in experimental marine mesocosms. Re‐analysis of their data fails to support this conclusion, which was apparently based on a statistical miscalculation.
