| differences in spatial autocorrelation between four sub-populations of alnus trabeculosa hand.-mazz. (betulaceae). | to investigate the spatial structure of alnus trabeculosa hand.-mazz, we compared three sub-populations at imaichi in tochigi prefecture and one sub-population at juo in ibaraki prefecture, japan. a total of 269 trees, covering 0.71 ha in total, were mapped and genetically analyzed using nine enzyme systems encoding 13 isozyme loci. there were no significant differences between the four sub-populations in terms of na,ne, h(o), h(e )and f(is). however, according to spatial autocorrelation analysi ... | 2002 | 12242643 |
