Differences between the two distances decreased with age for trees, but persisted for saplings and seedlings along the chronosequence. Singlestemmed saplings can divert resources to maximizing rates of vertical extension. Dominant, co-dominant, upper mid-canopy, lower mid-canopy and understorey strata (tree saplings only) are represented. A high sapling density and a dense herbaceous layer characterize the forest floor. Open circles are for the saplings on the edge of the path, filled circles for those in the understorey. Thus, crown traits, response rates of crown traits, and rates of light fluctuations might influence future growth and survival of saplings in the understorey. For saplings and seedlings we calculated density and basal area only. Therefore, the crown architectural and leaf traits strongly influence the growth and survival of saplings. Responses to canopy openings in architectural development of saplings in eight deciduous broad-leaved tree species. Mature trees supported more and different chrysomelid species than conspecific saplings. In mixed forest, 0.3 ha was sampled for both saplings and seedlings. Micro-environmental changes following gap creation allow seed germination, seedling establishment and sapling recruitment. These facts suggest that drought might be one of the important factors affecting leaf fall in saplings of this species. Crown architecture is one of the factors affecting sapling leaf area.
