Summary of SMA regression parameters (<i>n</i>, <i>p</i>, <i>r</i>², α, β, 95%CI, respectively) for allometric relationships between plant functional traits (shoot height, root/shoot ratio, branch length and leaf number) and plant size of the macrophyte species <i>Potamogeton maackianus</i> across transects of two lakes: e1, e2, e3 in Erhai Lake and n1, n2, n3, n4 in Niushanhu Lake.

<p><i>n</i>, samples number; <i>r</i>², correlation coefficient; <i>p</i>-values refer to correlation analyses following standardized major axes (SMA) procedures (see the Material and Methods section); α, slope; CIα, 95% CIs of the slope; β, intercept; CIβ, 95% CIs of the intercept;</p>*<p>: <i>p</i><0.05; **: <i>p</i><0.01; ***: <i>p</i><0.001.
