Other claims from this paper (5)
- Observation During self-thinning, simulated stand density and biomass per ground area followed a power relationship irrespective of initial density or allocation pattern.
- Observation Simulated light competition in a crowded stand was asymmetrically two-sided.
- Observation Height-growth type plants showed greater competitive asymmetry than diameter-growth type plants.
- Observation The simulated effect of competition on individual growth converged to a stationary state even while stand structure changed greatly.
- Method / resource The authors proposed a new general functional form for growth rate G(t, x) in crowded stands.
