Factors controlling decomposition of soil organic matter in fallow systems of the high tropical Andes: A field simulation approach using 14C- and 15N- labelled plant material
(2006)
N-rich (C:N ¼ 27) and N-poor (C:N ¼ 130) wheat straw, labelled with 14C and 15N, was incubated for 2 yr in two major ecosystems of the upper elevation belt of cultivation in the high Andes: the moist Paramo (precipitation ...
Nitrogen and phosphorus as limiting factors for growth and primary production in a flooded savanna in the Venezuelan Llanos
(2006)
The effects of N, P, NP and NPKS application on plant growth, above-ground primary production and N and P accumulation in the above-ground
biomass of a flooded savanna were assessed over two growth cycles. Application ...
Flowering and fruit production dynamics of sweet pepper (Capsicum chinense Jacq) under different shade conditions in a humid tropical region
(2006)
Growing sweet pepper (C. chinense) under shade has increased in the region south of Lake Maracaibo in Venezuela. We studied the effects of different shade conditions on the dynamics of flowering and fruit production of C. ...

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 ...
