Table 4. Analysis of molecular variance (AMOVA) from haplotypic frequencies for Sodalis glossinidius microsatellite data.

Source of variation	d. f.	Variance components	Percentage of variation	Fixation indices / P-value
Among groups	1	0.009	1.93	0.019 (FCT)/0.252
Among populations within groups	2	0.001	0.29	0.003 (FSC)/0.333
Among all populations	240	0.432	97.78	0.022 (FST)/0.006

Groups correspond to the two HAT foci, Bipindi (S. glossinidius population in Ebimimbang) and Campo (Campo Beach (CB)/Ipono, Akak, and Mabiogo populations). The three fixation indices are: F_CT, which can be interpreted as the relative divergence between HAT foci, F_SC, corresponding to the relative divergence between populations within the Campo focus, and F_ST, corresponding to the relative divergence between populations.
