Dispersion around response curve fitted using Eq. (5) assuming heteroscedasticity. This displays leaf dry weight against leaf area in arithmetical scale and response curve (median) estimated by the heteroscedastic regression model of Eqs. (5) and (6) (red lines). Also shown is region comprising 95% of leaf dry weight values observed for a given value of leaf area
