Table 5. Associations between geographical and qualitative population variables (factors) and genetic diversity and rarity (h_Nei, Nei’s diversity index; Nei, 1987; DW, frequency down-weighted marker values; N_r, number of rare alleles), as tested using the generalized linear model (GLM).

Geographical groups: IP, Iberian Peninsula; M, Morocco; CI, Canary Islands. All the values are indicated as mean ±SE. Different letters indicate significant differences in the multiple comparison test at P < 0.05, performed after the bootstrapped GLM.
