Linear models comparing hydraulic traits between coarse roots and branches of 13 woody angiosperms in a seasonally dry Ethiopian Highland forest.

Trait	contrast	SE	df	t.ratio	p.value
Dh	22	6.2	24	3.6	0.0014
CD	-36	21	24	-1.7	0.096
F	9.3	2.6	24	3.6	0.0015
$K_S^{pot}$	34	11	24	3.1	0.0044
$K_S^{hydr}$	7.2	1.3	23	6.1	3.5e-06
WD	-0.11	0.038	24	-2.9	0.0079

Contrasts are calculated as marginal means of roots minus marginal means of branches per trait. Traits are: Hydraulically weighted conduit diameter (D_h, µm), conduit density (CD, n mm^-2), conduit lumen fraction (F, %), potential ( $K_S^{pot}$ ) and xylem-specific conductivity ( $K_S^{hydr}$ , kg m^-1 MPa^-1 s^-1), and wood density (WD, g cm^-3).
