We used the Maxent algorithm, which estimates a target probability
distribution by finding the probability associated with
the maximum entropy (or the closest to a uniform distribution)
(Phillips et al., 2006). The Maxent approach is useful primarily
because it can be applied to analyze small and presence-only
datasets (Wisz et al., 2008). The area under the curve (AUC) of the
receiver-operating graph (ROC) was used to estimate the success
and failure of the prediction during the modeling process with a
set of test data (30% of the data) (Fielding and Bell, 1997). The AUC
values vary from 0 to 1. A value of 1 indicates the highest accuracy
