Table 2.

Final GLM results for response metrics in all years pooled at three radii from glacial fronts. Bold numbers indicate p < 0.05. GLMs at 10 km were estimated with quasi-likelihood model structures to account for overdispersion for sum total visits (all time periods) and proportion of narwhals visiting glaciers. Dashes indicate covariate was not included in the final model; blanks indicate models fail to converge at the smaller radii.
