Abstract	:	Treefall gaps in rainforest landscapes play a crucial role in providingopportunities for establishment and growth of rare, light-demanding plants such asPassiflora vines in Corcovado rainforests, Costa Rica. This study considers the interplayof landscape dynamics with plant life history traits and strategies in an ephemeral patchnetwork.In Chapter One, I show how patch quality dynamics and propagule dispersalaffect colonization of treefall gaps by Passiflora vitifolia. Recruitment required highpatch quality, exceeding 3 hours of sunlight and patches closed after about 6 years.Colonization by seed dispersal (80 ) was constrained by patch quality and isolation,while clonal growth from dormant plants (20 ) was limited to rare adjacent patches.Since patch turnover is critical in these systems, Chapter Two is focused on factorsaffecting canopy structure. I showed that prior landuse altered the dynamics.
