Table 3. Mantel tests for correlations between-population pairwise Q _STs for the three quantitative traits (larval period, metamorphic mass and growth rate), difference in altitude and geographic distance.

Matrix 1		Matrix 2
Dependent matrix	Trait	Independent matrix	r	P-value
QST	Larval period	FST	0.08	0.64
		Altitude difference	0.71	<0.001
		Geo. distance	0.68	<0.001
	Mass	FST	0.28	0.09
		Altitude difference	0.80	<0.001
		Geo. distance	0.83	<0.001
	Growth	FST	0.29	0.09
		Altitude difference	0.60	<0.001
		Geo. distance	0.66	<0.001

Matrix 1 is the dependent variable (Q_ST), whereas matrix 2 is the independent variable (F_ST, difference in altitude or geographic distance).P-value <0.05 are indicated in bold font.
