Figure 2. Influence of soil environment (soil water in spring, acidity and nutrients) on initial and mature seed productivity.

Values of individual-level seed productivity have been averaged for a time period of 10 years (from 2002 to 2012) and relativized by m² of tree basal area. Quercus canariensis has been represented with black symbols and solid lines, whereas Quercus suber with white symbols and dashed lines. Lines represent the best-fitted models (details in S1 Table).
