For each organization level (between species and between MLLs and MLGs within species) the probability (P) that the observed number of monocultures at a given sampling level (ant mounds, soil samples and aphid chambers) could have resulted from a random distribution of aphids was estimated using a bootstrap approach with 1000 iterations. P values below 0.05 (bold Figures) indicate deviations from a random distribution.
