Fig. 5

– Each panel shows: on top, the partial dependence plots, depicting the effect of a variable on the response, after accounting for the average effects of the other covariates in the model. We show the marginal effects (including a smooth representation of such effects, to aid interpretation) of the three most influential variables in the habitat models on the probability of presence of Pterodroma madeira and P. deserta, with respective relative variable importance (VI) in the top right corner. On the bottom, a violin plot depicting the density curves of the used (opaque, upper half of the violin) and available (transparent, lower half of the violin) explanatory variables. Results for Pterodroma madeira and P. deserta are shown in red and in gold, respectively
