Appendix B. Generalized Linear Mixed Models used to explain the number of agonistic interactions experienced during homing in relation to the deviation of the homing path and to the density of damselfish along the homing path.

TABLE B1. Generalized Linear Mixed Models used to explain (a) the number of agonistic interactions experienced during homing in relationship to the deviation of the homing path from the alternative route maximizing the use of reef and (b) the relationship between the number of agonistic interactions received and the density of damselfish along the homing path. Parameter estimates, standard errors (SE), and the 95% confidence intervals of each parameter are presented. All models include a constant. For the configuration predictor, we used a treatment contrast and Continuous configuration was the contrast. Predictors in bold do not contain zero within the 95% confidence intervals.
