Epiphytes represent a key component in tropical forests. They are affected by anthropogenic and natural disturbances suffered by forests, since they depend on their hosts and the microclimatic conditions they generate. We analyzed differences in abundance, species richness, and vertical distributions of epiphytic bromeliads in primary and disturbed forests. We found a higher abundance (5316 individuals) and species richness (8 species) of bromeliads in disturbed forest than in primary forest (1360 individuals and 4 species, respectively). Most bromeliads (97%) were found on , a dominant tree with rough bark in the disturbed forest (gallery forest). Bromeliads were more abundant in the middle of the tree and diminished towards the trunk base and the upper crown. was the most abundant bromeliad, and the size categories of this species differentially colonize trees in gallery forest according to Johansson zones; seedlings of . abundantly colonize the upper canopy, and juveniles colonize the middle canopy or secondary branches. Gallery forest represents an important reservoir for epiphytic bromeliads. Hence, it is important to extend this kind of study to wetland sites to understand the role they play as a habitat for epiphytes, as well as the dynamics and ecological processes that occur in such habitats.
附生植物是热带森林的关键组成部分。由于它们依赖宿主以及宿主所营造的微气候条件，所以会受到森林遭受的人为和自然干扰的影响。我们分析了原生林和干扰林中附生凤梨科植物在丰度、物种丰富度和垂直分布上的差异。我们发现，干扰林中凤梨科植物的丰度（5316株个体）和物种丰富度（8种）高于原生林（分别为1360株个体和4种）。大多数凤梨科植物（97%）生长在 上， 是干扰林（长廊林）中一种树皮粗糙的优势树种。凤梨科植物在树的中部更为丰富，向树干基部和树冠上部逐渐减少。 是最为丰富的凤梨科植物，根据约翰松区域，该物种的不同大小类别在长廊林中对树木的定植情况不同； 的幼苗大量定植在上层树冠，幼株定植在中层树冠或次生枝条上。长廊林是附生凤梨科植物的重要储存库。因此，将这类研究扩展到湿地环境很重要，以便了解它们作为附生植物栖息地所起的作用，以及这类栖息地中发生的动态变化和生态过程。
