Table 4 Summary statistics and standardized effect size (Hedges’g) for paired t-test between control and experimental plots (controls are set as reference group).

From: Lack of detectable genetic isolation in the cyclic rodent Microtus arvalis despite large landscape fragmentation owing to transportation infrastructures

Paired t-test (control versus experimental)

H1: true difference in means is not equal to 0

  1. Response variables are: observed heterozygosity (Ho), unbiased expected heterozygosity (uHe), allelic richness (Ar) and their homologous between sides within plots computations (DIF), genetic variation within plots (σbw) genetic differentiation metrics (Fst and G”st) and partial mantel r (rGd, rDps, rLrm) as a measure of genetic dissimilarities/similarities within plots.
