Abstract

The composition and diversity of vascular epiphytes was studied in four types of forests at the Puerto Abeja river basin, in the southeast region of the Chiribiquete National Natural Park, Colombian Guayana. The forests are named as: riparian or periodically flooded forest (R), upland forest (TF), transitional forest (T), and “Varillar” (V). In 500 m2 of each forest type, vascular epiphytes were screened in all phorophytes with a DBH > 2,5 cm. Of the 1110 trees found, 406 of them harbour epiphytes, with the greater proportion of phorophytes in TF and R. A total of 2015 individual vascular epiphytes were recorded (879 in R, 514 in TF, 405 in T and 217 in V), that included 183 species, 71 genera and 27 families (157 species and 20 families of angiosperms and 25 species and seven families of pteridiohytes). R and TF were the most specious (with 100 and 94 species respectively), while V was the poorest (with just 30 species). T and V exhibited 1–2 species with exceeding relative density values, while in R and TF none of the species had a distinct abundance. The Orchidaceae and Dryopteridaceae families were always part of the most important families (FIV) in all the forests; while families like Araceae, Bromeliaceae, Clusiacae, Grammitidaceae, Hymenophyllaceae, and Polypodiaceae, had an important significance in some of them. In R and TF the most specious families were Araceae and Orchidaceae, with the latter also being the most specious in T and V. According to similarity coefficients based on presence/absence and abundance of species, R and TF presented the highest similarity, while V was differentiated from them, and T could not be distinguished significantly from the others. Of all the epiphyte species, 68 (36,8%) were found in two or more forests and 117 (63,2%) in only one of them.
