Fig. 2. Tests of boat presence (B) and location (L) effects on transitions between preceding behavior (P) and succeeding behavior (S). Models and their respective goodness-of-fit G² statistics, degrees of freedom (df), and Akaike Information Critera (AIC) values are shown in the boxes. Terms added, with the corresponding increment in G² and degrees of freedom, are shown along the arrows (adapted from Caswell 2001).
