对南美洲圭亚那的干燥常绿(Walaba)森林中成熟的Eperua树上附生苔藓和地衣的区系和生态学进行了研究。使用登山技术，从树基到树冠最高的树枝都对树木进行了采样。附生植物种类和生活型垂直分布格局明显。许多物种，特别是叶状地衣，似乎对瓦拉巴森林中的优势树种--大花Eperua Grandiflora或Eperua Fallcata(豆科)--具有优先或排他性。特别关注了冠层上部枝条上物种丰富的附生植被，包括两类物种：太阳附生植物和先锋植物(附生植物)。
A floristic and ecological study of epiphytic bryophytes and lichens on standing mature Eperua trees was carried out in dry evergreen (walaba) forest in Guyana, South America. The trees were sampled from their base up to the highest canopy twigs, using mountaineering techniques. Clear vertical distribution patterns of epiphytic species and life-forms were found. Many species, particularly foliose lichens, appear to be preferential or exclusive to either Eperua grandiflora or E. falcata (Leguminosae), which are the dominant trees in the walaba forest. special attention is given to the species-rich epiphyte vegetation on the upper canopy twigs, which include two categories of species: the sun epiphytes and the pioneers (faculative epiphylls).
