In the tropical rainforest of the Tai National Park (ivory Coast), only 20.6 percent of the 160 species of trees recorded are colonized by hemi-epiphytic figs. These figs are not randomly distributed among the host trees; some common host species are proportionately much less colonized than other less common species. The comparative statistical analysis of the structural characters of colonized and noncolonized trees suggests a model of tree structure favoring colonization by figs. Still, if these characters combined converge toward light access, which agrees with the evolution of figs toward hemi-epiphytism, part of this work and the subsequent discussion tend to show that hemi-epiphytic figs are interacting with other influencing factors, such as the presence or absence of epiphytic ferns and orchids.
