| Résumé : |
The spatial genetic differentiation among European beech stands in western Germany was analysed by a new method. The genetic structure at 8 enzyme gene loci of lOO sarnpled populations was used as data base. The data represent authors' own results and published data from 8 different studies. For 10 geographic distance classes [h] from 0 to 500 km, the average genetic distance J(h between the populations for each single gene locus, a gene-pool distance J(hk) and the semivariances ,(hk) of genetic diversity Ugam were computed. Significant deviation from random spatial genetic structure was teste by permutation analysis. ln many cases (Lap-B, Mdh-B, Mdh-C and 6Pgdh-C) the mean genetic distance h J between stands with spatial distance up to 200 km was significantly smaller and the gene[...]
