Table 3. Summary of heterozygosity estimates (HE) and Allelic Richness (AR) for the two negative control populations—each with two time points, and standard errors (SE).
Species | Site | Year | N | HEXP | SE | P(EL) | AR | SE | P(EL) |
An. gambiae (M) | Tiko, Cameroon | September, 2003 | 52 | 0.739 | 0.028 | 8.6 | 0.70 | ||
August, 2006 | 52 | 0.711 | 0.044 | 0.44 | 8.9 | 0.92 | 0.51 | ||
Fanzana, Mali | August, 2002 | 43 | 0.803 | 0.031 | 13.00 | 1.193 | |||
September, 2006 | 89 | 0.801 | 0.031 | 0.78 | 15.417 | 1.264 | 0.30 |
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.
