Online Resource 2In this Online Resource, we show the results and summary statistics of seasonal Brunner-Dette-Munk (BDM) contrasts for sunfleck frequency classes (Tables 9 and 10) and sunfleck frequency in Aldea del Fresno (Fig. 5).

Table 9 Summary statistics of seasonal contrasts of direct PPFD classes in Aldea del Fresno.

Table 10 Summary statistics of seasonal contrasts of direct PPFD classes in San Luis

Fig. 5Sunfleck frequencies in Aldea del Fresno

Table 9Summary statistics of seasonal contrasts of direct PPFD classes in Aldea del Fresno. Mm: mid-morning; Md: midday. We provide P-values in text format to facilitate the visualization of the results.

DF1: Degrees of freedom of the factor (Season with two levels: summervs.winter)

DF2: Degrees of freedom of the whole model

F*: non-parametric ANOVA-like F

P(F>F*): P-value; α=0.05

* p<0.05; n.s.: non-significant

Dashes (-) indicate PPFD classes that were not analysed because all values were equal to zero

N=5 trees

Fig. 5Average sunfleck frequencies (number of seconds) as a function of classes of cumulative direct PAR per period of the day in Aldea del Fresno in the middle-crown in summer (A) and winter (B), and in the inner-crown in summer (C) and winter (D). Closed circles: mid-morning; open circles: midday. Asterisks indicate significant mean rank differences between periods of the day for each PPFD class from BDM tests. *: p<0.05; **: p<0.01; ***: p<0.001; N=5 trees
