Along for the ride or missing it altogether: exploring the host specificity and diversity of haemogregarines in the Canary Islands

Table 1 AMOVA tests of genetic structure for haplotypes B1 to E

Source of variation	df	SS	Var. comp.	Var. %	ɸ-statistic^a	P-value^b
By island
Among islands	6	107.70	1.12	69.32	ɸ_ST = 0.65	>> 0.001
Among locations within islands	22	6.86	-0.06	-3.90	ɸ_SC = -0.13	0.68
Within locations	89	49.74	0.56	34.58	ɸ_CT = 0.69	>> 0.001
By Gallotia spp.
Among host species	3	104.19	1.40	72.82	ɸ_ST = 0.71	>> 0.001
Among locations within host spp.	25	10.38	-0.04	-1.87	ɸ_SC = -0.69	0.52
Within locations	89	49.74	0.56	29.05	ɸ_CT = 0.73	>> 0.001

^aThe ɸ-statistics indicate the degree of genetic differentiation within and among groups in relation to the total (i.e., zero would be a situation of panmixia and one total separation)
^bP-values were calculated from 1000 permutations
Abbreviations: df, degrees of freedom; SS, sums of squares; Var. comp., variance components; Var. %, percentage of variation
Results from the analysis performed in the Arlequin software, by island and by Gallotia host species. Numbers have been reduced to two decimals for presentation
