Functional relationships obtained with generalized additive models between DPM and environmental variables for the three acoustic populations: (a) ANT BW (explained deviance = 21.2%), (b) SEIO PBW (explained deviance = 57%), and c) SWIO PBW (explained deviance = 37.6%). Solid lines represent the estimated smooth functions and the dashed lines represent the approximate 95% confidence intervals. The x-axis corresponds to the linear predictor and the y-axis to the covariate. Tick marks on the x-axis show the distribution of data points.
