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).
