Abstract
The zonation patterns ofAvicennia bicolor andRhizophora racemosa were studied in a mangrove forest on the Pacific Coast of Costa Rica. Comparisons were made between the establishment, survival, and growth of both species in three plots, 1 ha each, located along the flooding gradient. Based on cohort analysis and reciprocal planting observations, it was concluded that species zonation was primarily regulated by the depth of tidal inundation and the differential ability of the propagules to become established. However, tidal sorting was not the only operative factor related to inundation. Drought and probably high soil salinities limited the survival and growth ofR. racemosa in the landward sections of the forest. Tidal sorting, however, confined propagules to zones where they probably had the highest likelihood of contributing to another generation.
