Summary of heterozygosity estimates (HE) and Allelic Richness (AR) for the two negative control populations—each with two time points, and standard errors (SE).

P values for tests of the null hypothesis that mean heterozygosity or allelic richness is the same between time points (based on a paired t-test) are also presented. One P(EL) value is reported for the pairwise comparison for statistical difference between estimates for the two time points. P-values for comparisons that showed significant differences are emboldened.
