F, dependent matrix of minor allele frequencies; RDA tests are of the form: F ~ independent matrices | covariate matrices. env., seven retained environmental variables; geog., three retained principal coordinates of neighbourhood matrices variables. Total explained, total adjusted R2 of individual fractions; Total confounded, total of individual fractions confounded between various combinations of environment and geography.
