Fig. 1.
Long-term population growth trajectory of A. mexicanum at LTS. (A) Population growth trajectories of adult palms over 39 y; the red line corresponds to the best-fit exponential model (generalized linear model with Poisson error; NT is population size at year T, 1,186 is the mean population density in 1975 (year 0), and 0.0289 is the intrinsic annual rate of increase). The red line corresponds to the best-fit relationship considering data from all plots and dates; gray lines (and letters) correspond to plots in closed sites with high (A, AA), medium (B, BB), and low (C, CC) population densities in 1975, and in tree-fall gap sites (D, DD). (B) Change in population size structure from 1975 to 2013.
