Local and regional determinants of vascular epiphytes mortality in the Andean mountains of Colombia

Abstract: In this study we present the first census of mortality of vascular epiphyte communities carried out at large-scale in mountains of the Andes. Our goal was to identify the main modes of death and the determinants variables on epiphytes mortality. During one year, we went behind the fate of...

Our goal was to identify the main modes of death and the determinants variables on epiphytes mortality. During one year, we went behind the fate of 4,247 epiphytes in 10 forests (116 host trees) located from 60 to 2900 m a.s.l. Our results suggested that the survival of epiphytes is limited primarily by the instability of substrate constituting a possible risk of extinction for those species with slow life cycles because of the impossibility to colonize new substrates quickly. The role of ET in the probability of death of the epiphytes indicated both the direct (limitation of the metabolism) and indirect impact (increasing the mechanical mortality) that climate change could have on the vascular epiphytes dynamics. The influence of local determinants clarified the effect of the microclimate in the dynamics of this non-tree growth component of the forest.Resumen: Se presenta el primer censo de mortalidad de comunidades epífitas vasculares llevado a cabo a gran escala en el noroccidente de los Andes colombianos. Nuestro objetivo fue identificar los principales modos de muerte y las variables que determinan la mortalidad de epífitas. Durante un año seguimos el destino de 4.247 epífitas hospedadas por 116 forofitos de 10 bosques localizados entre 60 y 2900 m.s.n.m. Nuestros resultados sugieren que la sobrevivencia de las epífitas es limitada principalmente por la dinámica del sustrato, constituyendo un riesgo de extinción para aquellas especies con ciclos de vida lentos ante la imposibilidad de colonizar nuevos sustratos rápidamente. El papel de la evapotranspiración en la mortalidad de epífitas indica el impacto directo (limitando el metabolismo) e indirecto (incrementando la mortalidad por factores mecánicos) que puede tener el cambio climático en la dinámica de las epífitas.
