Parameter estimates of the optimal univariate models for otolith carbon isotope ratios and increment width selected with AICc.

Estimates are given for all fixed effects with confidence intervals (CI) and significance (p). For the random effects residual variance (σ2), the variance associated with tested effects (τ00) and their intraclass correlation coefficient (ICC) are given. The number of observations used to fit model and the amount of variance explained (marginal and conditional R2) are specified.
