Tropical montane cloud forest

摘要: Tropical montane cloud forests (TMCFs) are covered in clouds and fog, by definition, abundant with mosses, lichens epiphytes. The hydrology of these ecosystems is poorly understood due to the extreme wetness, complex topography, remoteness, TMCF also susceptible several types disturbance. two main objectives this thesis were (i) study fire history a (ii) investigate changes water input secondary TMCF. Field studies conducted southern Mexico northern Costa Rica. Chimalapas region Oaxaca, was subjected fires during El Nino events 1997 1998. Previous evident from charcoal, which collected soil pits. Radiocarbon dating indicated that at least nine episodes have occurred area past 10, 000 years findings suggest there been repeated investigated TMCFs. Rican aimed estimate total horizontal rain fog (HP) edge interior Net capture defined as HP reached calculated throughfall + stemflow - vertical precipitation. Over 11-month measurement period, accumulated net decreased linearly forest (ca. 1200 mm) centre plot 20 m into (ca.-1900 mm).
