Table 2 Percentage of deviance explained, AIC (Akaike’s Information Criterion), θ parameter in the variance of the negative binomial distribution, basis dimension (k) and effective degrees of freedom (e.df) of the functional linear predictor and the spatial smooth according to model 1 and model 2 in both plots. Inventory 2001, Inventory 2006, Inventory 2010, and Inventory 2014 indicate the effective degrees of freedom of the spatial smooth during the four inventories in model 2
