| Understanding how diversity is maintained in species-rich communities, such as tropical forests, remains a challenge in ecology. Recent work suggests that the controversy between competing theories could be better resolved by considering the spatial scale at which different processes rule community assembly. Here we use individual species?area relationships (ISAR) to evaluate the spatial organization of tree diversity around individuals of different species in a completely-mapped tropical dry forest in south Ecuador. We test two hypotheses. First,stressful environmental conditions promote facilitative interactions that will generate spatial signals of accumulation of diversity around individual trees ? contrary to what has been reported in humid tropical forests. Second, spatial signals will shift through ontogeny. As, as larger, older trees generate new microsite conditions that affect the recruitment of younger, smaller trees. | |
