Abstract
In this work, we attempted to study the genetic differentiation between populations
of Quercus glauca in Taiwan using microsatellite markers to infer the evolutionary history
in the last glaciation stage. We found that Q. glauca has relatively high
within-population diversity (HE = 0.741) and low population differentiation (FST = 0.042),
but shows isolation by distance. The most-divergent populations, according to the average
FST for individual populations in comparison with every other population, were found in
populations Chinshuiying, Shanping and Hungyeh in southern Taiwan, and Paling in
north-central Taiwan. Moreover, populations Chinshuiying, Shanping and Paling were
recognized as being the source populations for gene recolonization after the last
glaciation stage. In addition, the three sites of Wushe, Yangmingshan, and Chinshuiying
exhibited the highest gene diversities which coincided with populations with the highest
chloroplast DNA variations. This may have resulted from an admixture of colonization
routes.
