Correction of statistical miscalculation slightly alters conclusions about diversity effects for Douglass et al. (2008).
While most of the conclusions about diversity effects in Douglass, J.G., Duffy, J.E. & Bruno, J.F. [Ecol. Lett., 11, 2008, 1] are upheld, correction of a statistical miscalculation indicates that grazer diversity and predator diversity had combined effects on responses, but did not have interactive effects as initially reported.
