Variable importance of the top-performing Random Forest model in classifying nesting activity of 21 Galapagos giant tortoises from triaxial acceleration. Values are reported as Mean Decrease Gini, a measure of the importance of each variable in predicting classifications across the ensemble of trees. Variables of a higher decrease Gini value indicate the variable made a greater contribution to model fit. Averages across iterations are shown with horizontal bars indicating the range. Validation methods include withholding a year (“Temporal”), random individuals (“Individual”), and a random subset of data (“Random”). Refer to Table 1 for detailed covariate descriptions
