【 摘 要 】

:The aim of this study was to characterize the demographic structure and spatial pattern ofCampomanesia xanthocarpa(Mart.) O. Berg, Myrcianthes gigantea(D. Legrand) D. Legrand and Myrciaria delicatula(DC.) O. Berg. Within one hectare of Ombrophilous Mixed Forest, all the three populations' individuals were counted and measured with regard to their height and diameter. From the collected data, the assessment of the demographic structure was realized after the individual's size classification. Spatial pattern was determined by applying the Standardized Morisita's Index. C. xanthocarpaand M. delicatulashowed an inverted-J frequency distribution in the individuals size classes, which differed fromM. giganteathat did not follow the same pattern. The spatial pattern ofC. xanthocarpaand M. delicatulapopulations was found mainly to be aggregated; whereas, M. gigantea showed spatial randomness. The three Myrtaceaepopulations responded differently with regard to structure and spatial distribution in sites with the same environmental filters.
