Resumen: A central concept in current models of tropical tree regeneration is that many species require a gap in order to regenerate. An operational approach to the analysis of regeneration is proposed here, focusing on effects of specific environmental factors, such as light availability, and evaluating processes in all juvenile stages for each species. Preliminary data are reported on the juvenile stages of 6 canopy tree species (Lecythis ampla, Minquartia guianensis, Pithecellobium pedicellare, Hymenolobium pulcherrimum, Hyeronima oblonga, Dipteryx panamensis) at the La Selva Biological Station, Costa Rica. The number of crowns above individuals decreased with increasing stem diameter. The 6 species did not differ in the number of crowns above juveniles <10 cm in diameter; however, marked interspecific differences existed in the 10-20 cm diameter class. For most juveniles of <10 cm diameter the incident light was lateral, and not from canopy openings directly above. Species did not differ in crown position for juveniles up to 10 cm diameter, but significant differences existed in the 10-20 cm class. Annual diameter increment was correlated with crown position for many species/size combinations. The differences in mortality rates of juveniles <1 cm diameter did not follow preliminary tolerance classifications. All juveniles 2-30 cm in diameter (N = 173) survived 2 yr. It is concluded that a simple classification based on dependency on gaps will not adequately categorize the regeneration process for these species
