There was no statistically significant inter-individual variation in the degree of plasticity nor covariation between the intercept and the slope for either spring snowpack (Slope Variance ± SE = 0.39 ± 1.68, Intercept/Slope Covariance ± SE = 1.07 ± 1.69, LRT₂ = 0.40, p-value = 0.82) or spring temperature (Slope Variance ± SE = 0.02 ± 1.45, Intercept/Slope Covariance ± SE = 0.27 ± 1.69, LRT₂ = -0.01, p-value = 1) (Figure 3).
