Abstract
The spatial distribution pattern of Tillandsia violacea Baker was studied along an altitudinal gradient in a temperate forest in "El Chico" National Park, Hidalgo, Mexico, with emphasis on the host tree species. Results clearly showed a clumped spatial distribution pattern in the four habitat types of host trees. We found a positive effect of altitude in the T. violacea abundance, a preference for Abies religiosa as host tree, and a relation between height of host trees and abundance of T. violacea. Se estudió el patrón de distribución espacial de Tillandsia violacea Baker en un gradiente altitudinal en un bosque templado en el Parque Nacional "El Chico," Hidalgo, México, con énfasis en la especie de árbol soporte. Nuestros resultados mostraron un patrón de distribución claramente agregado en los cuatro tipos de hábitat en el árbol soporte. Se encontró un efecto positivo de la altitud sobre la abundancia de T. violacea, y una tendencia de estas plantas a usar preferentemente Abies religiosa como árbol soporte. También se encontró una relación significativa entre la altura del árbol soporte y la abundancia de epífitas.
