Fig. 5
Time series showing mean group size per week at site W (a) and H (d). Black dots represent percent effort in weeks with less than 100% recording effort, and gray shading represents periods with no recording effort. Generalized Additive Model (GAM) results showing relationships between the probability of goose-beaked whale group sizes and Julian day (b) and (e), normalized time of day (NTOD, sunrise at 0 and sunset at −1/1 with blue shading representing nighttime, (f), and acoustic presence (c) and (g) with group size. GAMs are fit separately for each site, and not all predictors were retained during model selection for all sites. Rug plots show distribution of predictor variables. p value significance is denoted by ***p<0.001; **p<0.01; and *p<0.05. Model fit is shown as a black line, 95% confidence intervals are shown as either a shaded area (for smooths) or a dashed line (for factors).
