“…The results show that the arboreal soils were generally acidic. Gill and Onyibe (1986) obtained similar results in their phytosociological studies of epiphytic flora on Elaeis guineensis. The highest pH of 6.5 was obtained for the soils collected on Alstonia booneii, the tree species with 11 epiphytes, which was the lowest number of epiphytes recorded in this study.…”

As components of forest communities, epiphytes influence litter and nutrient cycling while providing shelter, nesting materials and food for arboreal animals, thereby promoting diversity. Their preference for certain tree species (phorophytes) influences biodiversity and distribution, but this association is poorly understood in the tropics. We assessed the diversity and spatial distribution of epiphytes associated with four phorophytes (Alstonia booneii, Peltophorum pterocarpum, Mangifera indica and Terminalia catappa) in southern Nigeria, with number of trees sampled as 4, 29, 32 and 44, respectively. The epiphytes were delineated, sampled and identified. Soil samples were collected from tree pockets for textural and pH analyses. On the four phorophytes, 265 epiphytes under seven species (Platycerium elephantotis, Microgamma owariensis, Nephrolepis biserrata, Funaria hygrometrica, Axonopus compressus, Commelina benghalensis and Ficus spp.) and five families (Polypoidaceae, Funariaceae, Poaceae, Commelinaceae and Moraceae) were recorded. The three most abundant were Funaria hygrometrica (109), Platycerium elephantotis (102) and Microgamma owariensis (44), being present on all four phorophytes. Funaria hygrometrica and Platycerium elephantotis were the most abundant on M. indica (32 each) and T. catappa (44 and 39, respectively). Nephrolepis biserrata appeared only once on T. catappa; so too did Axonopus compressus and Commelina benghalensis on P. pterocarpum. Altogether, A. booneii, P. pterocarpum, M. indica and T. catappa had 11, 62, 89 and 103 epiphytes, respectively. Funaria hygrometrica traversed three tree strata, while others were restricted to two or even one stratum. Canopy layer, middle stratum and lower portion hosted four, five and three epiphytic species, respectively out of the seven recorded, pointing to the relative importance of light, spaciousness and moisture, respectively in epiphyte abundance on trees. Epiphytes distribution on phorophytes was not influenced by texture of the arboreal soils, but was inversely related to their pH. This study has provided useful information on epiphyte-phorophyte association in tropical environments and deserves repetition with more tree species in more natural forests.

“…Species Distribution: Unequal distribution along vertical column in forests (Figs. 1 and 2) is regularly explained by variation on moisture, luminosity, substrate availability substrate characteristics (Waechter 1980, 1992, Gill & Onyibe 1986, Steege & Cornelissen 1989, Zimmermman & Olmsted 1992, Kernan & Fowler 1995, Kersten & Silva 2001. Brown (1990) stated that variations of microclimate, and substrate diameter, are the main factors responsible for epiphyte distribution pattern.…”

“…= %frequency in strata, Ind.= %frequency in host individuals. Gill & Onyibe (1986) considered ten important environmental factors to the establishment of epiphytic flora: host age, inclination, luminosity, humus deposition, host tree size, daily weather variation, seed dispersion, temperature, moisture and wind. Ingram & Nadkarni (1993) observed positive correlation between epiphytic biomass and branch size, and negative between biomass and branch inclination.…”

The study was carried out in a 3 000m 2 area of coastal Atlantic rain forest at Ilha do Mel island (25 o 30''S 48 o 23'W), on 100 assorted trees separated into 2 meter-high strata starting from the ground. In each stratum all of the occurring epiphytic species were recorded. The sampled species were grouped into three categories: exclusive, preferential, and indifferent, according to their abundance in each strata, and selective, preferential and indifferent, according to abundance on the forophytes. Intermediate strata registered the highest diversity. Six species were considered exclusive to one or two strata, 15 were restricted to some strata and 5 presented a broad distribution. No epiphytic species showed uniform horizontal distribution on the area. The epiphyte richness in a host tree varied from zero to 30. Regarding to fidelity on host tree species, few selective or preferential, and mainly indifferent epiphyte species, were found. A total of 82 epiphyte species were sampled in the surveyed tree, and the Wittaker plot indicate a highly dominant assemblage.

“…In oil palm plantation in Nigeria, Gill and Onyibe [21] revealed a total of 174 weeds comprising of five ferns, 52 monocotyledons, and 117 dicotyledons. A majority of the weeds, numbering 142 (81.6 %) were broad leaved, whereas 22 (12.6 %) were grasses, and remaining 10 (5.7 %) were sedges.…”
