瓶颈

Along the low altitudinal plateau edge, haplotypes A, B and C tended to be fixed or nearly fixed in different populations, indicating that the species may have survived the last glacial period in different refugia within this area, and the bottlenecks due to the repeated reduction and expansion of the population size resulted in the reduction of biodiversity.
