Allozyme surveys indicate that many woody species are highly polymorphic and maintain high levels of genetic variation within populations (reviewed by Hamrick and Godt 1989; Loveless and Hamrick 1984). This genetic variation, or diversity, is usually structured, with spatial and (or) temporal differences in the distribution of alleles of genotypes resulting for the joint action of mutation, migration, selection, and genetic drift. (Loveless and Hamrick 1984). The distribution of genetic diversity is hierarchical because the variation can be partitioned among individuals within a populations: several ecological factors factors and life-history characteristics may affect the distribution (cf. reviews by Hamrick et al, 1979, 1981; Hamrick 1983; Loveless and Hamrick 1984.)
