FIGURE 7 The centroid distributional shifts for Satyrium ciliatum, Satyrium nepalense, and Satyrium yunnanense
Figure 7 shows that the centroid of S. ciliatum ’s current habitat is located in Central Yunnan Province at 99°84’E and 27°27’N. Under SSP1-2.6, the centroid of suitable habitat will shift to 99°35’E and 27°87’N in the 2050s, and 98°69’E and 27°94’N in the 2070s. Under SSP5-8.5, the centroid of the future suitable region will be located at 98°86’E and 28°01’N in the 2050s. Under SSP5-8.5, the acceptable area’s centroid will relocate to 98°15’E and 28°91’N in the 2070s. In summary, we can see that the core distribution of S. ciliatum will shift to the northwest under both future emission trajectories (SSP1-2.6, SSP5-8.5). The centroid of the existing habitat for S. nepalenseis located in Southern Yunnan Province at 99°28’E and 27°15’N. Under SSP1-2.6, the centroid of the suitable region will shift to 98°79’E and 27 °69’N in the 2050s and 98°38’E and 27 °69’N in the 2070s. Under SSP5-8.5, the centroid of the future suitable region will be located at 98°82’E and 27°69’N in the 2050s. The centroid of the suitable region will relocate to 97°67’E and 28 °56’N in the 2070s under SSP5-8.5. The centroid of the current habitat for S. yunnanense is located in south Sichuan province at 102°67’E and 27°75’N. Under SSP1-2.6, the centroid of the suitable area will shift to 103°73’E and 29 °02’N in the 2050s, and 102°22’E and 28 °94’N in the 2070s. According to SSP5-8.5, the suitable area’s centroid will relocate to 101°91’E and 29 °68’N by the 2050s, then to 100°05’E and 30 °94’N in the 2070s.
