The percentage of variation explained in genetic and epigenetic loci accounted for by non-geographically-structured environmental variables [a], shared (geographically-structured) environmental variables [b], pure geographic factors [c], and undetermined component [d] analyzed based on environmental PC1.

Proportions of explained variation were obtained from variation partitioning by redundant analysis. F and P values are specified for testable fractions. Fraction [b] is untestable because the adjusted R2 value was obtained by subtraction ([a + b + c]-[a]-[c]) rather than by estimation.
