Summary: | The relationships between areal sizes of high, intermediate, low, and total
sum of habitats with low, intermediate and high suitability habitat ranges,
and the International Union for Conservation of Nature (IUCN) threatened
status of global terrestrial mammals were studied. Polyserial correlation
analysis showed that all types of areal size closely and positively
correlated with IUCN categories of threatened species. The results indicate
that area-based extinction risk assessment is feasible and reliable in
species’ conservation prioritization. Furthermore, the partial polyserial
correlation test indicates that significant correlations between the IUCN
threatened status of species and range sizes of high, intermediate and low
suitability habitats are not influenced by the polyserial correlation between
IUCN threatened status and total suitability habitat range size. Thus, the
prediction of species’ extinction risks can be accurately fulfilled by
evaluating the areal size of any one of total, high, intermediate or low
suitability ranges. The present study implies that if the area size
information of a totally suitable range is not available for species’
extinction risk assessment, the usage of areal sizes from any parts of
suitable habitats (high, intermediate or low) are effective surrogates. |
