Mountain cloud forests hold a high diversity and abundance of epiphyte plants. This high abundance promotes the establishment of multiple associations among epiphytes, which have been scarcely studied. Using experimental epiphyte mats, positive and negative effects, as well as both effects occurring simultaneously were found. However, more studies are necessary to determine the effect of both intra- and inter-specific associations occurring among all the species within the epiphyte community. The goal of this study was to determine both intra- and inter-specific associations established among epiphytes and their effects (positive, negative or neutral) within the community. Epiphyte identification, abundance and distance between closest neighbors were determined in 0.25 ha of a cloud forest in Central Mexico. Chi-squared tests and Haberman residuals were used to test the existence of significant associations and their effects (positive, negative or neutral). A two-way ANOVA was applied to test the effect of the epiphyte species, the association type (intra- vs. inter-specific) and the interaction between them on the distance between pairs of closest neighbor epiphytes. Significant epiphyte-epiphyte associations within the community were found (χ2 = 6317, d.f.= 196, P < 0 .0001). A total of 225 associations were found; out of these, 155 were neutral, 36 were negative, and 34 positive. Out of the total number of associations detected, 210 were interspecific and 15 were intraspecific. The fern Pleopeltis accicularis had the highest number of positive interspecific associations (4 with other ferns, 1 with the orchid Prostechea linkiana, and 1 with Peperomia tetraphylla). Contrastingly, P. tetraphylla (Piperaceae) and Tillandsia crypthanta (Bromeliaceae) had the highest number of negative interspecific associations (with 8 other epiphyte species). Among the intraspecific associations, 13 were positive; Prosthechea linkiana was the only species with neutral intraspecific associations, whereas Pleopletis acicularis was the only one with negative associations. Epiphyte-epiphyte distance was significantly affected by the species interacting (F12, 3060 = 25.27, P << 0.0001), the type of association (F1, 3060 = 203.0, P << 0.0001), and the interaction between those factors (F12, 3060 = 12.16, P<< 0.0001). Within interspecific associations Prosthechea linkiana (1.3 ± 0.55 cm) and Pleopeltis polylepis (25.9 ± 5.24 cm) had the shortest and greatest distance, respectively, with their closest neighbors. Likewise, Hintonella mexicana (8.5 ± 1.28 cm) and Tillandsia macoyana (16.16 ± 1.39 cm) had the shortest and greatest distance with their congeneric closest neighbors. Interspecific associations had a shortest mean distance (6.95 ± 0.29 cm) than the intraspecific ones (13.67 ± 0.4 cm). Six out of a total of 13 species included in the analysis had a significantly greater distance with their intraspecific closes neighbors (14.68 ± 0.76 cm) than with the interspecific ones (4.93 ± 0.32 cm). For seven epiphyte species, intra- and inter-specific mean distance (12.28 ± 0.36 cm) was similar. Intraspecific associations were predominantly positive (except in two species); whereas the interspecific associations were mainly neutral. Therefore, closest neighbor identity and distance between neighbors seem to have an important influence on the type of association established between pairs of epiphytes and, consequently, on the structure of the epiphyte community.
