The ecology of hemiepiphytes is very poorly understood. More appalling is the lack of information on hemiepiphyte vital rates and demography. Such information is essential to understand the ecology, management and conservation of this group that is an important component of tropical forest. Here, I aimed to fill some of these gaps in knowledge on hemiepiphyte ecology. I studied three sympatric secondary hemiepiphyte of the genus Heteropsis in the Colombian Amazon.
