Hypnum jutlandicum - Results of fitting a linear mixed-effects model to the cover data by maximizing the restricted log-likelihood. Columns show the denominator degrees of freedom, F-values, p-values from Wald tests for each term, and the \(\beta\) coefficients. The interaction terms (ty : Fnh3 etc.) give the change in cover per year per g N deposited m\({}^{-2}\) y\({}^{-1}\). Because we include interactions in the model, Fnh3, Fnh4, Fno3 and PK are effectively intercept terms, the effects of nitrogen deposition when time, t\({}_{y}\) = 0.
