FIGURE 4 Dynamic distribution change patterns of four Lamiaceae
species across different periods in the Third Pole. The yellow region
shows the area remained still (Unchanged), the green region shows the
new area to be colonized (Gained), and the blue region shows the area to
be lost (Lost).
Overall, in the future, species potential distribution areas
will expand in the high–altitude and high–latitude regions of the TP,
while continually contracting in the regions of the Hengduan Mountains
( Figure 3 and Figure 4). All species are facing a reduction in
their current potential distribution range of at least 8% up to as much
as 30%. Species with a higher current mean altitude exhibit more
pronounced distribution losses in the Hengduan Mountains (Table 1 and
Table 2). Warmer scenarios will accelerate the shifts with higher loss
and gain.
