研究了哥斯达黎加太平洋海岸红树林中白骨壤和红树的分区格局。对沿洪水梯度分布的三个样地（每块 1 公顷）中两种物种的定居、存活和生长进行了比较。基于队列分析和相互种植观察，得出的结论是，物种分区主要受潮汐淹没深度和繁殖体定植能力差异的调节。然而，潮汐排序并不是与洪水相关的唯一影响因素。干旱和可能的高土壤盐度限制了R.的生存和生长。总状花序生长在森林的向陆部分。然而，潮汐分类将繁殖体限制在最有可能为下一代做出贡献的区域。
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.
