periods
3.6 The centroid distribution shifts
The change in the potential distribution of Francois’ langur from 2021
to 2100 is shown in Figure 6. These models predicted that future global
change would promote the contraction of the potentially suitable
habitats for Francois’ langur, with the total suitable habitats
decreasing. In particular, most of the suitable habitat in Chongqing and
Guizhou would contract sharply. Francois’ langur would expand slightly
in southwestern Guangxi and western Chongqing. The potential core
distribution of Francois’ langur would move southeast from southern
Guizhou to northern Guangxi under future climate conditions.
Furthermore, the distance of the centroid shifts were 109.43km,
145.99km, 82.26km, and 227.09km in 2021-2040, 2041-2060, 2061-2080, and
2081-2100, respectively, compared to the current (Figure 7).
