Population dynamics of A. mexicanum at the LTS. Population growth rate (λ) vs. initial population density (D) during three periods: 1975–1981 (A), 1981–2005 (B), and 2005–2013 (C). Annual mortality rate (AMR; ind/ind per year; continuous line) and annual recruitment rate (ARR; ind/ind per year; dashed line) vs. initial population density for 1975–1981 (D), 1981–2005 (E), and 2005–2013 (F). In all cases, λ was calculated as (N_t/N₀)^(1/t), where N₀ and N_t are population density (juvenile and adult palms) at year 0 and t years after, respectively. In A and D, best-fit significant parameter regressions are shown; in all other cases, the trends were nonsignificant.
