Notes

Abstract:
Epiphytes play an integral role in nutrient cycling in tropical rainforests and are often found on the trunks of tree ferns. This study examined the role of elevation on epiphyte load on tree ferns. Ninety-six tree ferns were examined along an elevational gradient, and data were collected regarding the identity and dimensions of the trees as well as their elevations and the number and type of epiphytes on their trunks. Epiphyte abundance was not significantly correlated with elevation, but epiphyte load was significantly related to tree fern morphology. The Alsophila, whose spines likely provide a prime habitat for epiphytes, possessed a significantly larger epiphyte load than Cyathea, which does not possess spines (P = 0.0062). Further study regarding tree fern morphologies and epiphyte load should be conducted. ( ,, )
Abstract:
Las epífitas juegan un rol integral en el ciclo de nutrientes en el bosque lluvioso tropical y a menudo se encuentran en los troncos de helechos arborescentes. Este estudio examinó el rol de la elevación en la carga de epífitas en los helechos arborescentes. Noventa y seis helechos arborescentes fueron examinados a lo largo de un gradiente altitudinal y se colectó datos con respecto a la identidad y dimensiones de los helechos con respecto a sus elevaciones y al número y tipo de epífitas en sus troncos. La abundancia de epífitas no estuvo significativamente correlacionada con la elevación, pero la carga de epífitas estuvo significativamente relacionada con la morfología del helecho arborescente. Alsophila, cuyas espinas probablemente proveen un mejor hábitat para las epífitas, tuvo una carga significativamente mayor de epífitas que Cyathea, la cual no tiene espinas (P = 0.0062). Debe de estudiarse la morfología de los helechos arborescentes y la respectiva carga de epífitas.
