Background and aims: Filmy ferns (Hymenophyllum) are notable for their reliance on moist microsites for survival, though the determinants of their assemblage in the habitat remain partially undefined.

| description |
Background and aims: Filmy ferns (Hymenophyllum) are notable for their reliance on moist microsites for survival, though the determinants of their assemblage in the habitat remain partially undefined. The aim of this study was to investigate how five habitat variables – stem orientation (N-S-E-W), forophyte species, presence of climbers, diameter at breast height (DBH) and canopy cover – affect the composition of film fern communities in a temperate forest fragment.
M&M: 120 trees were sampled along a transect through the centre of the forest, assessing the presence/absence of ferns up to 2.3 m above the stem. Data analysis was performed using PERMANOVA with 10,000 permutations followed by multiple comparisons to detect differences in fern composition between forophyte species.
Results: A significant influence of both tree DBH (pseudo-F = 21.617; p < 0.001) and forophyte species identity (pseudo-F = 4.123; p < 0.001) was detected. Multiple comparisons revealed significant differences (pseudo-T, p < 0.05) in fern assemblages associated with forophyte species groups.
Conclusions: The results indicate that certain physical and biotic characteristics of the forophyte are crucial for the structuring of film fern communities, other environmental factors initially considered may not be as important or their effect may be masked by homogeneity of sampling conditions, insufficient sample size or effect of anthropogenic disturbances. |

Introducción y objetivo: los helechos película (Hymenophyllum) se destacan por su dependencia de micrositios húmedos para su supervivencia, aunque los factores determinantes de su ensamblaje en el hábitat permanecen parcialmente indefinidos. El objetivo de este estudio fue explorar cómo cinco variables del hábitat —la orientación del tronco (N-S-E-O), la especie forófita, la presencia de trepadoras, el diámetro a la altura del pecho (DAP), y la cobertura del dosel— afectan la composición de comunidades de helechos película en un fragmento de bosque templado. M&M: se muestrearon 120 árboles a lo largo de un transecto trazado por el centro del bosque, donde se examinó la presencia-ausencia de helechos hasta una altura de 2.3 m sobre el tronco. El análisis de datos se realizó mediante PERMANOVA con 10.000 permutaciones, seguido de comparaciones múltiples para discernir diferencias en la composición de helechos entre las especies forófitas. Resultados: se detectó una influencia significativa tanto del DAP de los árboles (Pseudo-F = 21,617; p < 0,001) como de la identidad de las especies forófitas (Pseudo-F = 4,123; P < 0,001). A través de las comparaciones múltiples, se revelaron variaciones significativas (Pseudo-t, p < 0.05) en los ensambles de helechos asociados a grupos de especies forófitas. Conclusiones: Los resultados indican que ciertas características físicas y bióticas del forófito son cruciales para la estructuración de las comunidades de helechos película, otros factores ambientales considerados inicialmente podrían no ser tan importantes o su efecto podría estar enmascarado por la homogeneidad de las condiciones de muestreo, tamaño muestreal insuficiente o efecto de perturbaciones antrópicas.
