2.3 MaxEnt model ensembles
MaxEnt software (http://www.cs.princeton.edu/, version 3.4.1) was employed for creating the Satyrium habitat suitability model. Models that produced 75% of the occurrence records were used for training, while those that produced 25% of the occurrence records were employed for testing (16).
The number of iterations and the number of background points were both limited to 1000 and 10,000, respectively. The model’s performance was improved by repeating the ensemble processes using 10-fold cross-validation (8). The logistical output of the MaxEnt software, which revealed environmental appropriateness for S. ciliatum, S. nepalense, and S. yunnanense with values no higher than one, was used to create the final prospective distribution map. For additional analysis, the MaxEnt results were combined in ArcGIS 10.2, and the prospective habitat categories were regrouped into four groups: highly suitable habitat (0.50-1.00), moderately habitat (0.30-0.50), poorly suitable habitat (0.10-0.30), and unsuitable habitat (0-0.10).
