Extended Data Fig. 6: Examples of relationships between a functional trait and tree species growth.

Each panel presents the relationship between the Specific Leaf Area (SLA) value and the growth rate value of different tree species growing in a given common garden. Scatter plots present three sites of the European Atlantic Network (a, b, c) and three sites of the Tree Diversity Network (d, e, f). These sites are also identified in Fig. 2b. For panels from a-f, the statistics of the regressions (level of confidence of the error band = 0.95) were respectively: t = −2.13, −0.55, +1.85, −2.05, +1.33, and +3.40; df = 17, 18, 21, 10, 8, and 10; n = 19, 20, 23, 12, 10, and 12.
