开花和结果的时间和水平进行了研究，在哥伦比亚西部的前山地雨林。花卉生产的季节性比水果生产少，高峰期的结果并不总是紧随着开花活动的高峰期。与季节性热带环境相比，水果产量在全年中分布更均匀，但有两个小的果实高峰集中在一年中较潮湿的部分。林冠物种比林下物种按比例较少产生鸟类分散的果实，几乎所有的林下树木都产生这种类型的果实。紫藤属的果实种类在一年中有一定的顺序，但果实中的个体总数季节性变化。这种变化显然被其他树木结果活动的增加所抵消，因为鸟类水果的供应没有明显的季节性衰退。
The timing and levels of flowering and fruiting were studied in a premontane rain forest in western Colombia. Flower production is less seasonal than fruit production, and periods of peak fruiting do not always closely follow the periods of higher flowering activity. Fruit production is more equitably distributed through the year than in seasonal tropical environments, but there are two small fruiting peaks that center on the wetter portions of the year. Proportionally fewer canopy species than understory species produce bird-dispersed fruits, and almost all understory trees produce this type of fruit. Species of Miconia fruit sequentially through the year, but the total number of individuals in fruit varies seasonally. This variation is apparently offset by an increase in fruiting activity of other trees as there is no marked seasonal depression in the availability of fruit for birds.
