2.5 Model performance comparison
We evaluated and compared the performances of each habitat suitability
model and the ensemble model for each species using AUC and True
Statistic Skill (TSS). We considered a model with AUC > 0.9
as excellent, 0.8-0.9 as good, 0.7-0.8 as moderate and 0.6-0.7 as poor.
We took a model with TSS > 0.75 as indicating excellent,
0.4-0.75 as good and < 0.4 as poor (Eskildsen et al., 2013).
Variables contribution for each model of each species was calculated in
Biomod 2. Besides, the response curves of presence points to the most
significant variables in each model were produced and interpreted for
each species.
