Table 3 ANOVA to test for factors affecting intra-genomic variability within invasive genotype (Ia) of Amphistegina lobifera and Wilcoxon test for pairwise comparisons of different oceanic basins and different status of invasion.

From: Invasion success of a Lessepsian symbiont-bearing foraminifera linked to high dispersal ability, preadaptation and suppression of sexual reproduction
