The average AUC value for the Bsal distribution model was 0.917
(SD ± 0.047), signifying strong model performance. The top three
variables for model predictions included mean diurnal range, maximum
temperature of the warmest month, and precipitation during the coldest
quarter (Fig. 1A).
The modeling predictions estimated that only a small fraction of
suitable habitats for Bsal occurrences exists under current
climate conditions, with patchy distribution in the subtropical
evergreen forests of the Guangxi region. (Fig. 1A). The anticipated
habitats for Bsal occurrence were situated in southwestern areas
near the coastlines. Among the 27 wild sampling sites, 14 were deemed
suitable for Bsal , with suitability levels ranging from low to
high.
