t0“The Relationship of Leaf Area and Foliage Biomass to Sapwood Conducting Area in Four Subalpine Forest Tree Species”
e0“Leaf dry weight and area were strongly correlated with sapwood area measured at 1.37 m, but leaf area per unit sapwood area varied widely among species: 1.88 m²·cm-2 for subalpine fir, 0.72 for Engelmann spruce, 0.44 for lodgepole pine, and 0.19 for aspen”

Other claims from this paper (7)
- Association Leaf dry weight and leaf area were strongly correlated with sapwood area measured at 1.37 m.
- Observation Leaf area per unit sapwood area was 1.88 m²·cm-2 in subalpine fir.
- Observation Leaf area per unit sapwood area was 0.72 in Engelmann spruce.
- Observation Leaf area per unit sapwood area was 0.44 in lodgepole pine.
- Association The leaf area to sapwood area relationship was nearly constant for different portions of the crown.
- Association The upper portion of a larger tree had the same leaf area to sapwood area ratio as the entire crown of a smaller tree.
- Mechanism The results support the hypothesis of a physiological balance between conducting tissue and the water requirements of the shoot.
