From: Humpback whale migrations to Antarctic summer foraging grounds through the southwest Pacific Ocean
Smooths of generalized additive mixed modelling. (GAMM) terms showing the influence of environmental variables on whale ‘search’ behaviour (b). Locations of observations are shown as tick marks on the x-axes. Solid lines are the estimates of the smooths, grey areas indicate standard errors of the estimated smooths. The y-axis indicates the effect of the smooth function of each covariate upon the probability of being in ‘search’ behaviour; with a lower (higher) value indicating reduced (increased) probability. (a) Bathymetric gradient, (b) summer chlorophyll climatology, (c) distance to ice edge, (d) ice melt rate, (e) coefficient of variation (CV) of ice concentration two months prior, and (f) mean ice concentration one month prior.
