Summary of the generalised additive model for assessing the influence of each predictor to the relative abundance manta rays (M. alfredi) exhibiting cruising, cleaning and foraging behaviour at LEI.

The significance (p-value) of each term was based on the Likelihood-ratio test of comparing the full model and the model omitting the respective predictor, and only significant predictors were included in each model. The percentage of deviance explained (% Dev. Exp.) represents the importance of each predictor.
