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).
