Table 2. Results of the general additive mixed model (GAMM) of daily and monthly variation in singular call and phrase production rates. For each sound type, F -ratios and P -values for each of the three variables (Location, Month, and Time-of-day, TOD) are presented; as well as percent deviance explained by the model and generalized cross-validation (GCV) score. Location was classified as inshore or offshore, and sample size was n =351 for each sound type. Variables with significant P -values are marked with an asterisk and italicized.
