  1. aOU alternative corresponds to Ornstein–Uhlenbeck models with different numbers of parameters. Here, only the model with the best AIC value is reported, see the full set of OU models in summarized in the Additional file 1: Table S6. (AICc = corrected Akaike Information Criterion values, ΔAIC Delta AICc and ω = Akaike weights)
