Comparison of temperature measurements between the dry and humid slopes in the study region.

Parameter	Dry slope	Humid slope	t	p
Residuals (mean annual air temperature)	0.13 ± 0.58	-0.33 ± 0.49	1.79	0.09
Residuals (mean annual soil temperature)	0.09 ± 0.65	-0.03 ± 0.50	0.31	0.77
Absolute minimum air temperature	-2.58 ± 1.28	-2.33 ± 0.60	-0.56	0.58
Residuals (absolute minimum soil temperature)	-0.22 ± 0.53	0.09 ± 0.81	-0.73	0.49
Absolute maximum air temperature	23.10 ± 5.65	16.52 ± 0.50	3.87	0.01
Residuals (absolute maximum soil temperature)	0.10 ± 0.73	-0.39 ± 0.58	1.18	0.27
Residuals (mean air temp. of growing season)	0.56 ± 0.45	-0.26 ± 0.37	3.17	0.01
Residuals (mean soil temp. of growing season)	-0.02 ± 0.59	0.18 ± 0.76	-0.48	0.65

For those factors for which significant linear relationships to elevation were recovered when combining data from both dry and humid slopes, t-tests were used to compare the residuals of the dry against the humid sites. For those two parameters without significant elevational trends, the raw values were compared.
