Figure 2

Differentiation snails at three levels of genetic integration in four oak stands. For six microsatellite loci scored in four stands of oak (R, B, S, E) the differentiation snails were constructed from the snail components Δ j in Tab. 1. Dotted circles mark the symmetric population differentiation Δ SD . Within each snail, the quantitative differences among the components are slight. Each snail differs qualitatively in the ranking of the stands from the other two (i.e., covariation C < 1 for each comparison). The significantly large increase in the radius Δ SD of the snails with each higher integration level confirms the differentiation among the stands for form of gene association.
