Other claims from this paper (6)
- Method / resource Self-shading model predicted optimal foliage fractal dimensions between 2 and 3 depending on light interception and crown size.
- Observation Measured foliage fractal dimension was less than 3 in gymnosperm trees.
- Association Foliage fractal dimension depended weakly on crown size.
- Association Foliage biomass scaled with crown woody biomass at exponent 0·78.
- Mechanism Deviation in crown woody biomass and length scaling could explain the observed scaling.
- Observation Authors conclude gymnosperm foliage deviates from volume filling.
