Functional diversity of wetland vegetation in the high-andean Páramo, Venezuela
(Spehn, E., Liberman, M., Körner, C. (Eds), 2006)
Variaciones microclimáticas en invernadero: efecto sobre las relaciones hídricas e intercambio de gases en pimentón (Capsicum annuum)
(2005)
En este estudio se compararon los efectos de días despejados con altas radiaciones (1700 mmol m-2 s-1) y días nublados
(por debajo de 1000 µmol m-2 s-1) sobre el microclima en invernaderos y las relaciones hídricas e ...
Relaciones hídricas e intercambio de gases en Theobroma cacao var. Guasare bajo períodos de déficit hídrico
(2005)
Se evaluó las relaciones hídricas y el intercambio de gases en Theobroma cacao var. Guasare bajo períodos de déficit
hídrico. Se midieron las variables microclimáticas (temperatura del aire, humedad relativa y radiación ...
Determination of water-soluble and total extractable polyphenolics in biomass, necromass and decomposing plant material using near-infrared reflectance spectroscopy (NIRS)
(2005)
Near infrared reflectance spectroscopy (NIRS) was used to predict the water-soluble and total extractable polyphenolics of plant material. Different life forms (forbs, grasses, shrubs, giant rosettes), organs (leaves, ...
Participatory planning for biodiversity conservation in the high tropical andes: are farmers interested?
(2005)
The success of participatory conservation projects depends greatly on the interest shown by the local population and on the strategies used to incorporate all stakeholders from the initial stages. In the highly diverse ...
Seasonal variations in leaf gas exchange of platain cv. Hartón (Musa AAB) under different soil water conditions in a himid tropical region
(2005)
The seasonal effect of soil water availability on leaf gas exchange of plantain plants cv. Hartón growing on two different texture soils (loamy and clayey) were evaluated. Soil water deficits corresponded to 48, 24 and 4 ...
Modelling the effects of fire and competition on the dynamics of neotropical savannas: from plants to community
(2005)
Savannas are one of the most extensive biomes of the world and are subject to intense pressures due to large human populations using this ecosystem, even though it is characterized by low crop yields and poor nutritional ...
Mapping savanna ecosystems of the Llanos del Orinoco using multitemporal NOAA satellite imagery
(2004)
Monthly composites NOAA-advanced very high resolution radiometer (AVHRR) normalized difference vegetation index (NDVI) images (June 1992–October 1993) were used to analyze the phenology of savanna ecosystems in the Llanos ...
Seed dispersal in Palicourea rigida H.B.K, a common treelet species from neotropical savannas
(2001)
The dispersal system of Palicourea rigida (Rubiaceae), a common
woody species of neotropical savannas, was studied in a seasonal Venezuelan savanna.
Production and consumption of fruits, dispersal agents, feeding ...
