Response to Comment on “Mycorrhizal association as a primary control of the CO 2 fertilization effect”C.Terrer MorenoauthorS.ViccaauthorB.A.HungateauthorR.P.PhillipsauthorP.B.ReichauthorO.FranklinauthorB.D.StockerauthorJ.B.FisherauthorI.C.PrenticeauthorNorby et al. center their critique on the design of the data set and the response variable used.
