Table 1. Fixed effects of stand and species related attributes on the probability of stem breakage from the ice storm.

Fixed effects	Δ AIC	p		dir
Stand properties
Stand age	−9.13	0.001 **		↓
Richness	1.20	0.371
Stand axis 1 (e.g. vegetation cover)	−0.30	0.129
Stand axis 2 (e.g. decreasing functional diversity)	1.66	0.559
Species traits
Xylem axis 1 (e.g. crystals)	1.75	0.617
Xylem axis 2 (e.g. decreasing vessel diameter)	−0.21	0.137
Mechanics axis 1 (e.g. decreasing shering stress)	1.27	0.393
Mechanics axis 2 (e.g. wood elasticity)	1.99	0.943
Wood density	1.25	0.386
Leaf axis 1 (e.g. SLA)	−3.32	0.021 *		↓
Leaf axis 2 (e.g. dentate leaves)	1.95	0.828

The column “dir” indicates the direction of the effect, in this case a decrease (↓) with increasing axes scores. Significant differences are indicated as ** at level of <0.01 and * at the level of <0.05.
