Table 4 LMM coefficients for the following dependent variables: tree age, number of stems per tree, quadratic mean diameter (QD), height, and crown diameter using only reproductive trees (n = 451). The variable QD is log-transformed. The marginal and conditional r2 is also provided (delta for number of stems). The levels sex: female, site: Maranchón, and gradient: long-existing are included in the intercept
