Abstract

39 species of vascular epiphytes were found in a 625-m(2) plot in a cloud forest in Veracruz, Mexico. Epiphyte biomass was estimated for all species in six zones distinguished on each tree > 10 cm in DBH: stembase, lower stem, upper stem, branches > 20 cm, branches from 5 - 20 cm and branches < 5 cm diameter. Branches were additionally separated according to their position in the upper, middle or lower canopy. Total dry matter of green organs was 318 kg/ha. Dominance/diversity curvesfitted best to the lognormal model. Principal Coordinate Analysis showed that canopy height and branch thickness are both important factorsand also that the stem base was the most distinct zone. Microhabitat preferences and niche overlap of the frequent species proved some degree of resource partitioning within the canopy. Ecophysiological characters possibly responsible for these preferences and implications for conservation are discussed.
