Title
Evidence for “diminishing returns” from the scaling of stem diameter and specific leaf area
Karl J. Niklas; Edward D. Cobb American Journal of Botany 2008. doi:10.3732/ajb.0800034
Other claims from this paper (5)
- Observation The scaling exponent for total leaf area vs leaf mass was less than one in woody dicot species.
- Observation The exponent for leaf area per leaf mass vs stem diameter was negative in woody dicot species.
- Observation Size effects on the scaling exponents were statistically significant.
- Observation The scaling exponents differed among species and different species groupings.
- Observation The diminishing returns hypothesis receives statistical support in woody dicot species.
