Relationship between the within-plot Shannon index of genetic diversity and the first between-group Eigenanalysis (BPCA) score of amplified fragment length polymorphism (AFLP) profiles among plots. The Gaussian additive model is significant (P=0.03, deviance explained=0.178) and indicates that plots with intermediate AFLP profiles show a significantly higher genetic diversity than the extreme ones forming homogeneous patches. Such a pattern is expected for nuclear genes under a ‘reshuffling effect’.
