Figure 4: Predicted habitat suitability surfaces based on ENMs for (A) Speyeria atlantis , (B) northern S. hesperis , and (C) southern S. hesperis . For each lineage, five ENMs were built, each withholding a different 20% of occurrence localities used for model evaluation. Background points (n = 10,000) were generated within each lineage’s buffered minimum convex polygon to sample available habitat. The average of the five models were used to predict habitat suitability across the entire study area. Each 1-km grid cell received a habitat suitability score ranging from 0–1, with higher values indicating higher suitability.
