The Population Dynamics of a Long-Lived Conifer (Pinus palustris)

摘要: We investigated the demography and spatial pattern of an old-growth longleaf pine population using a large plot in which all trees at least 2 cm dbh were mapped tagged for individual recognition. The was uneven age size; tree size correlated positively with age. Large or old only loosely aggregated, forming background matrix that filled forest. In contrast, juvenile highly aggregated located areas low adult densities. Recruitment within this thus appears to occur primarily open spaces created by deaths trees. Variable time lags may before colonization spaces, however, because temporal variation seed production occurrence summer ground fires. absence gaps age-class distribution indicated recruitment has occurred frequently past 250 years. Neither age- nor size-class distributions, stab...
