Abstract

We investigated the spatial distribution of genotypes among 20 and seven Korean populations of Eurya japonica Thunb. and E. emarginata (Thunb. ) Makino, widespread and broadleaved evergreen dioecious trees native to East Asia, using spatial autocorrelation analysis of enzyme polymorphism. Korean populations of E. japonica are large, abundant, and contiguous, while populations of E. emarginata in Korea are small, isolated in few localities. Although the two species have very similar life history traits (e.g., obligate outcrossing, high fecundity, and longgeneration time), the observed pattern of genetic distribution among populations of E. japonica appears to be different from that of E. emarginata examined. For example, the number of overall significant correlograms is different from each species (10%, 3/29 in E. japonica vs. 40%, 8/20 in E. emarginata). The average Moran's I values for E. japonica were very similar among three distance classes (-0.01, -0.07, and -0.07), whereas these values for E. emarginata were 0.02, -0.18, and -0.34 for each distance class. The results indicate that more genetic structuring among Korean populations exists in E. emarginata than E. japonica. The distribution patterns and effective population sizes found in the two species may be important factors in shaping the observed genetic structures among populations of the species.
