Key Points

To evaluate how variation in sample size and species ecological specialization influences the predictive performance of four distinct species distribution modeling methods.
Tested four distribution modeling algorithms (Bioclim, Domain, GARP, and Maxent) across 18 species characterized by varying degrees of ecological specialization.
Assessed performance across six sample size treatments (including 5, 10, and 25 occurrences) using three separate evaluation metrics adapted for presence-only data.
Maxent demonstrated the highest accuracy and utility at very small sample sizes (5, 10, and 25 occurrences), whereas Domain and GARP exhibited moderate resilience and Bioclim performed poorly.
Model accuracy was systematically higher for species possessing narrow environmental tolerances and restricted geographic ranges compared to ecological generalists.
