| Variable |
Description | |
|---|---|---|
| Measured traits | ||
| H | Height (cm) | Total height of each tree in 2007, 2009 and 2010 |
| F. Rep | Female reproduction | Presence or absence of seed cones in each tree, yearly from 2007 |
| M.Rep | Male reproduction | Presence or absence of pollen cones in each tree in 2009 and 2010 |

| μ | Intercept of reproduction-size logistic regression at the population level | |
| α | Slope of reproduction-size logistic regression at the population level | |
| TSFR | Median threshold size for first reproduction (cm) | Size at which the probability for a tree within a population to have reached sexual maturity was 50 %, equal to μ/α |
| SRI | Smallest reproductive individual (cm) | Size of the smallest reproductive individual in the population |
| LVI | Largest vegetative individual (cm) | Size of the largest vegetative individual in the population |
