Although predictions suggest that the potential distribution areas of individual species may expand, the future of these species remains uncertain due to the accumulation of risks from multiple aspects. There may be overly optimistic estimations regarding the future situation of alpine species. The optimistic predictions imply that species need to full track climate change. It is almost impossible to occupy all newly predicted suitable areas, while most species will experience various levels of contraction in their current suitable areas, which poses an urgent threat to the species. Migration lag frequently occurs in alpine species due to their limited dispersive ability, ultimately resulting in incomplete filling of the predicted range (Dullinger et al., 2012; Morgan & Venn, 2017). Features such as shorter height, less efficient vectors, and lower reproductive investment result in their limited dispersal abilities. As reference, most alpine species in Snowy Mountains have a dispersal distance of less than 10 meters (Morgan & Venn, 2017). Geographical barriers, habitat fragmentation and limited dispersal abilities have led to a persistent lack of gene flow among alpine species populations, resulting in considerable genetic divergence (Luo et al., 2017).
