| 英文摘要 | The main Korean mountain range (the so-called "Baekdudaegan"), which stretches from north to south across most of the country, has been thought to harbor glacial refugia for boreal plant species, where they likely found relatively stable habitats and maintained large population sizes. Under this scenario, high levels of genetic variation and low or moderate degree of differentiation among populations within these species were expected. To test this hypothesis, we examined levels of allozyme diversity (14 loci) in eight populations of the boreal herb Lilium cernuum, which in Korea occurs largely along the Baekdudaegan and, as a reference, in eight populations of its congener Lilium amabile, a temperate species that is distributed on lower hillsides in peripheral regions of the Baekdudaegan. L. cernuum harbored higher levels of genetic variation within populations than L. amabile (%P = 49.1 vs. 25.0, A = 1.71 vs. 1.34, and H-e = 0.159 vs. 0.048). Genetic differentiation among populations was low for both species (F-ST = 0.119 and 0.014 for L. cernuum and L. amabile, respectively). A series of historical and ecological factors may explain the contrasting levels of genetic diversity between L. cemuum and L. amabile: occurrence within the main ranges of the Baekdudaegan (enduring the glacial periods in macrorefugia) vs. low elevation peripheral areas (in microrefugia) and shade-tolerant vs. shade-intolerant. This study, as well as previous population genetics studies, strongly suggests that the Baekdudaegan merits high priority for conservation given its proposed role as glacial refugia for montane species.
