Background and aims: Ferns and lycophytes are highly diverse in Neotropical forests, and their distribution is influenced by various biotic and abiotic factors, including disturbance.

Background and aims: Ferns and lycophytes are highly diverse in Neotropical forests, and their distribution is influenced by various biotic and abiotic factors, including disturbance. This study analyzes the effect of some of these factors on the diversity of these plants in a sub-Andean forest.
M&M: Four transects of 400 m2 (80×5 m) were established, two in highly disturbed sites, grassland, and stream edge, and two in the forest. Each transect was divided into 16 plots where all terrestrial and epiphytic individuals were recorded. Clustering analyses were performed to recognize the presence of floristic groups, and a canonical correlation analysis was performed to identify how soil chemistry and vegetation structure affect the composition and diversity of these plants.
Results: A total of 4935 individuals were found, representing 42 species. Amauropelta rudis (Kunze) Pic. Serm. (2485 individuals) and Asplenium flabellulatum Kunze (1190 individuals) were the dominant terrestrial species. The clustering and ordination analyses revealed that the plots of open sites are more related to each other than to those of the forest. Species of open sites are more correlated with a lower layer of litter, a lower height and coverage of trees or saplings, a higher concentration of aluminum and a lower concentration of sodium.
Conclusions: Ferns and lycophytes are influenced by the environmental, structural and disturbance conditions of the site where they grow. Key words Disturbance, diversity, edaphic factors, multivariate analysis, pteridophytes, richness, structural factors. |

Introducción y objetivos: Los helechos y licófitos son muy diversos en los bosques neotropicales y su distribución está influenciada por diversos factores bióticos y abióticos, incluida la perturbación. En este estudio se analiza el efecto de algunos de estos factores sobre la diversidad de estas plantas en un bosque subandino. M&M: Se establecieron cuatro transectos de 400 m2 (80×5 m), dos en sitios altamente perturbados, pradera y borde de quebrada, y dos en el bosque. Cada transecto se dividió en 16 parcelas donde se registraron todos los individuos terrestres y epífitos. Se realizaron análisis de agrupamiento para reconocer la presencia de grupos florísticos, y un análisis de correlación canónica para identificar cómo la química del suelo y la estructura de la vegetación afectan la composición y diversidad de estas plantas. Resultados: Se encontraron 4935 individuos que representan 42 especies. Amauropelta rudis (Kunze) Pic. Serm. (2485 individuos) y Asplenium flabellulatum Kunze (1190 individuos) fueron las especies terrestres dominantes. Los análisis de agrupamiento y ordenación revelaron que las parcelas de sitios abiertos están más relacionadas entre sí que con las del bosque. Las especies de zonas abiertas están más correlacionadas con una menor capa de hojarasca, una menor altura y cobertura de árboles grandes y pequeños, una mayor concentración de aluminio y una menor concentración de sodio. Conclusiones: Los helechos y licófitos están influenciados por las condiciones ambientales, estructurales y de perturbación del sitio donde crecen.
