Figure 1. Differences between the plant functional types in (a)
turgor loss point (πtlp), (b) vegetative height
(log10-transformed), (c) specific leaf area (SLA), (d)
intrinsic water use efficiency measured by carbon stable isotopes
(δ13C) and (e) leaf dry matter content (LDMC) and.
Bars are mean + 1 standard error.
Figure 2. Standardized major axis of the relationships between
turgor loss point (πtlp) and leaf dry matter content
(LDMC), specific leaf area (SLA), intrinsic water use efficiency
measured as carbon stable isotopes ratio (δ13C) and
vegetative height (log10-transformed). Left panel
presents actual data and right panel presents data after accounting for
the phylogenetical relatedness (‘PIC’; phylogenetic independent
contrasts). Purple dots and lines denote forbs, green dots and lines
denote graminoids, grey dashed line is based on all data. ‘All’, all
data combined; ‘F’, forbs; ‘G’, graminoids; ‘F = G’, slopes of the
relationship do not differ significantly between forbs and graminoids.
