Figure 6: Flowering abundance of small species under the first
quartile height (‘1st quartile’; A), flowering
abundance of small species under the median height (‘median’, B),
flowering richness of ‘1st quartile’ small species (C) and flowering
richness of ‘median’ small species (D) vs. mean light penetration (%)
per plot. We used log10 transformations on ‘1st
quartile’ and ‘median’ small species flowering abundance and fit all
with linear models. Flowering ‘1st quartile’ small
species (A; P = 0.027, R2 = 0.08), flowering
‘median’ small species (B; P = 0.012, R2 =
0.11) as well as richness of flowering ‘median’ small species (D;P = 0.014, R2 = 0.10) significantly declined as
mean light penetration decreased. Flowering ‘1st quartile’ species
richness was not significantly affected by light penetration (C).
