Summary of heterozygosity estimates (<i>H_E</i>) and Allelic Richness (<i>A_R</i>) for the two negative control populations—each with two time points, and standard errors (SE).

<p><i>P</i> 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 <i>P_(EL)</i> 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.
