“…However, the scatter plot shows that there is a cloud of points that fill an area with right triangle pattern. This is because the sampling method used, produce a lot of data noise, requiring to use a different data analysis from traditional, one more relevant to macroecology (Rosabal et al, 2010). This noise can also be a cause of why the NMS patterns were not clear.…”

“…Epiphyte sampling: A total of 43 phorophytes (tree) with a high coverage of epiphytes were chosen. For nonvascular epiphyte sampling, we measured (cm 2 ) all thalli located from the base of the trunk up to 2 m height, calculating coverage by species (McCune, 1990;Rosabal, Burgaz, & de la Masa, 2010). The coverage was measured as the area covered by each thallus over the sampled trunk expressed as a percentage (Rosabal et al, 2010).…”

In the case of vascular epiphytes, all individuals on the trees were counted, recording the number of individuals per species, understanding each individual as the smallest unit distinguishable.…”

<span>Los bosques húmedos tropicales son ecosistemas que acumulan una alta biodiversidad y alto endemismo, principalmente en la ecorregión del Chocó biogeográfico. La vegetación en esta zona ha sido poco estudiada, sobre todo para el grupo de las epífitas. De esta forma, el objetivo de este trabajo fue evaluar la diversidad y composición de estas plantas (vasculares y no vasculares) en una zona de transición entre bosque húmedo tropical y bosque seco tropical en el Chocó biogeográfico. Se muestrearon 43 árboles con abundante cobertura de epífitas: las no vasculares fueron muestreadas hasta los 2 m de altura, mientras que las vasculares a lo largo de todo el forófito. Los datos se agruparon en seis zonas a lo largo de la vía, siendo la zona 1 la más cercana al Pacífico (bosque húmedo tropical) y la zona 6 la más cercana al enclave subxerofítico del río Dagua (bosque seco tropical); también se agruparon dependiendo de la exposición a la luz en tres micrositios: abiertos, semi abiertos y cerrados. Se recolectaron 485 ejemplares de epífitas no vasculares pertenecientes a 77 especies de líquenes, cinco de hepáticas y ocho de musgos, para un total de 90 especies. Por otro lado, se registraron 5 987 individuos pertenecientes a 24 especies de epífitas vasculares, siendo la familia Bromeliaceae la más rica en especies (seis especies), seguida de Gesneriaceae, Orchidaceae y Polypodiaceae (cuatro especies). Se encontraron 25 nuevos registros de líquenes para Colombia, 26 para el Chocó biogeográfico, también 11 nuevos registros de epífitas vasculares para Chocó biogeográfico. La riqueza y diversidad de las comunidades de no vasculares fueron afectadas por la zona y el micrositio donde estaban los árboles, mientras que en las comunidades de vasculares, fueron afectadas por la zona a lo largo de la carretera.</span>

“…Rosabal et al (2012Rosabal et al ( , 2013 found that lichens with crustose biotype and sexual reproduction are the most frequent strategies in the montane rainforest of Gran Piedra. As well, Rosabal et al (2010) describe the microclimatic conditions as suitable for the establishment of lichens in the understory of this forest. Thus, the limiting resource on these phorophytes is the size of the habitat.…”

“…Pese a que se han realizado pocos estudios en el trópico en lo concerniente a la preferencia de forófito de los líquenes (Sipman & Harris 1989, Gradstein 1992, Wolf 1993, Gradstein et al 1996, Merwin & Nadkarni 2001, Coppins & Wolseley 2002, Cáceres et al 2007, Rosabal et al 2010, se ha encontrado que estos organismos muestran patrones similares a los de zonas templadas (Sipman & Harris 1989, Boonpragob & Polyiam 2007. Por ejemplo, en dos bosques de Guyana, los líquenes presentaron una ligera especificidad de forófito y una pronunciada zonación vertical desde la vegetación baja de sombra hasta el dosel de los árboles (Cornelissen & ter Steege 1989, Montfoort & Ek 1990).…”

Especificidad de forófito y preferencias microambientales de los líquenes cortícolas en cinco forófitos del bosque premontano de finca Zíngara, Cali, Colombia Abstract: Phorophyte specificity and microenvironmental preferences of corticolous lichens in five phorophyte species from premontane forest of Finca Zíngara, Cali, Colombia). Lichenized fungi or lichens are organisms that have been little studied in the tropics and which distribution is affected by microenvironmental factors and substrate characteristics. The present study aimed to identify phorophyte specificity and microenvironmental preferences of corticolous lichens in five phorophyte species from premontane forest of the farm Finca Zingara in Cali, Colombia. For this, five individuals were selected from five tree species (phorophytes). Lichen species present in a 0.50x0.20m 2 quadrant located in the trunk of each tree at a height of 1.3m were identified. Substrate parameters such as bark pH, Diameter Breast Height (DBH) and bark structure were measured. Also, microenvironmental factors including temperature, humidity and irradiance were determined. In order to detect phorophyte preferences, a non-metric multidimensional scaling (NMS) and indicator species analysis were made. Spearman correlation analysis was used to assert the relationship between environmental variables and groupings found in the NMS. A total of 69 species of lichens were found, of which 37 were identified to species, 18 to genera and 14 were not determined because they were sterile or had no spores. NMS showed that some individuals of the same tree species were grouped alongside the analysis dimensions, and they were related with the factors of light intensity, temperature and DBH. Only three lichens with preference for certain tree species were found (Arthonia microsperma by Meriania sp., Cladonia ceratophylla and sorediado 8 by Clusia sp.), suggesting absence of phorophyte preferences. Thus, it can be concluded that lichens from the study area do not show phorophyte preference, but their distribution is affected by light, temperature and DBH. Rev. Biol. Trop. 60 (2): 843-856.
