Table 3 Results from exact test of population differentiation and M values for each species

Species	R–PR		R–YK		PR–YK		South–YK
Species	p value	M	p-value	M	p-value	M	p-value
I. incerta	1.000	12.46	> 0.0001	0.52	> 0.0001	0.85	> 0.0001
M. columbi	0.112	13.53	> 0.0001	1.10	0.00103	0.85	> 0.0001
T. fumipennis	1.000	(infinite)	0.00571	0.39	0.00323	0.49	0.00151

Differentiation was examined for each pair of regions, as well as for the structure established by Geneland. Values in italic indicate significant p-values (p > 0.05). R Prairies, PR Peace River region, YK Yukon, South includes the Prairies and Peace River. M values (number of absolute migrants between regions per generation) are also included for each pair of regions
