Floristic and functional characterization of vascular epiphytes associated with palms of the genus Phoenix L. in Bogotá, Colombia ; Caracterización florística y funcional de las epífitas vasculares asociadas a palmas del género Phoenix L. en Bogotá, Colombia

Palms of the Phoenix genus have been introduced for aesthetic purposes in different cities around the world and have been reported to have communities of epiphytic plants growing on them. This research evaluated the epiphytic flora found in the necromass and the crowns of palms of the Phoenix genus in Bogotá, Colombia, and the traits that make them establish there. For this purpose, 66 individuals were sampled in the localities of Kennedy and Bosa, and the Importance Value Index (IVI), the Shannon-Wiener index (H), the functional diversity index (FRic), the functional equity (FEve) and functional divergence (FDiv) and the similarity with the epiphytes found in palms of the same genus in four cities around the world through the Jaccard index were calculated. The results obtained show a high floristic richness and diversity, with the presence of 42 species, 36 genera and 19 families. Asteraceae, Poaceae, Polygonaceae and Amaranthaceae were the most important families. Regarding functional traits, most species had life history traits suitable for the colonization of novel or intervened areas, finding that only 7% of the species are true epiphytes. ; Las palmas del género Phoenix han sido introducidas con fines estéticos en diferentes ciudades del mundo y se ha reportado que tienen comunidades de plantas epifitas creciendo sobre ellas. Esta investigación evaluó la flora epifita encontrada en la necromasa y en las copas de palmas de este género en Bogotá, Colombia, y los rasgos que hacen que se establezca allí. Para esto se muestrearon 66 individuos en las localidades de Kennedy y Bosa, se calculó el Índice de Valor de Importancia (IVI), el índice de Shannon-Wiener (H), el índice de diversidad funcional (FRic), la equidad funcional (FEve) y divergencia funcional (FDiv) y la similaridad con las epifitas encontradas en palmas del mismo género en cuatro ciudades del mundo a través del índice de Jaccard. Los resultados obtenidos muestran una alta riqueza y diversidad florística, con la presencia de 42 especies, 36 ...
