GLM models obtained by stepwise selection of habitat variables influencing king penguins from the Falkland Islands and South Georgia.

Parameters are shown in the order of importance, derived from the stepwise selection. In addition, the plus or minus signs preceding the parameters indicate whether there is a positive or negative effect. For each competing model, the Akaike Information Criterion (AIC) and the difference between the AIC of the current model and the most-parsimonious model (ΔAIC) are given. The most parsimonious model for each case are marked in bold and mean area-under-the-curve (AUC) values computed for 100 replicate parameterizations of the models. All 100 replicates had AUC≥0.7.
