Functional Diversity in Tropical High Elevation Giant Rosettes
(Goldstein G, Santiago LS (Eds). Tropical Tree Physiology. Springer., Suiza, 2016-03-04)Strong daily temperature variations, seasonal soil water availability and high air evaporative demands play an essential role in adaptive responses of tropical high elevation mountain plants. Giant rosettes are a perfect ... -

Gas exchange in sweet pepper (Capsicum chinense Jacq) under different light conditions
(Journal of Agricultural Science, 3 (3):134-142, Venezuela, 2011-09)Plants in the tropics are exposed to high radiation and consequently high temperature and evaporative demands throughout the year. Under these conditions, physiological processes and final yield may negatively affect ... -
Gas exchange, growth, flowering and furit production in sweet pepper (Capsicum chinenseJacq) along a thermal gradient determined by altitudinal differences in a tropical region
(Experimental Agriculture 15: doi:10.1017/S0014479715000071., Inglaterra, 2016-04)A common practice in some South American countries consists in moving around Capsicum chinense cultivars between regions where edaphoclimatic conditions differ notably. The purpose of this research was to compare and relate ... -

Heterogeneidad del paisaje de selva semicaducifolia montana en tres cuencas de Los Andes venezolanos
(SABER ULA, Venezuela, 2011-12)Se realizó un análisis comparativo de la heterogeneidad del paisaje de selva semicaducifolia montana en tres cuencas con diferente grado y tipo de intervención. Se elaboraron mapas de cobertura de la vegetación natural e ... -
How do two Lupinus species respond to temperature along an altitudinal gradient in the Venezuelan Andes?
(Revista Chilena de Historia Natural 81: 335-343, Chile, 2008)Temperature determines plant formations and species distribution along altitudinal gradients. Plants in the tropical high Andes, through different physiological and morphological characteristics, respond to freezing night ... -
Increase in the woody component of seasonal savannas under different fire regimes in Calabozo, Venezuela
(SABER ULA, 2005-06-27)Abstract Aim We tested the hypothesis that exclusion from fire and cattle is responsible for the increase in tree cover in open savanna vegetation. Location Four plots in open savanna vegetation from the Calabozo region ... -
Influencia de la altitud y la distancia al Lago de Maracaibo en la caracterización pluviométrica del estado Trujillo, Venezuela
(Venezuela, 2000)Con el fin de determinar la influencia de algunas variables físico-geográficas en la caracterización de la pluviometría del estado Trujillo y áreas adyacentes, se conformó una base de datos con precipitación mensual, altitud ... -
Intercepción y drenaje en las epifitas de dosel de una selva nublada Andina Venezolana
(Ataroff, M. y J.F. Silva (eds) 2005. Dinámica Hídrica en Sistemas Neotropicales. ICAE, Universidad de Los Andes, Mérida, Venezuela, Venezuela, 2005)En la selva nublada de La Mucuy, Andes de Venezuela, estudiamos la capacidad de interceptar y retener agua por parte de ramas con epifitas del dosel. Secciones de ramas de 1,4m, colectadas en árboles de tres parcelas entre ... -
Interception of water by pastures of Pennisetum clandestinum Hochst. ex Chiov. and Melinis minutiflora Beauv
(Agricultural and Forest Meteorology 149: 1616-1620, Venezuela, 2009-10)The conversion of montane cloud forests into pastures for grazing cattle is the main cause of important impacts on rivers and streams in most of the Andes. In order to evaluate the effects of vegetation changes we need to ... -
