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., 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 ...
Functional Diversity in Tropical High Elevation Giant Rosettes
(Goldstein G, Santiago LS (Eds). Tropical Tree Physiology. Springer., 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 ...
Shrubs as foundation species in a high tropical alpine ecosystem: a multi-scale analysis of plant spatial interactions
(Plant Ecology and Diversity, 2014-09)
Background: Studies on plant–plant interactions in alpine ecosystems show a strong bias for temperate vs. tropical latitudes and pay limited attention to the implications of biophysical heterogeneity beyond the local plant ...
Freezing avoidance in tropical Andean bamboos
(The Journal of the American Bamboo Society 27:1-10., 2014)
Frost resistance was compared in five species of different life forms in the neotropical woody
bamboo genus
Chusquea growing along a cloud forest-paramo gradient, between 2250-4010 m
a.s.l. in the Venezuelan Andes. C. ...
La evolución de la investigación ecológica en los páramos de Venezuela: múltiples visiones de un ecosistema único
(Medina, E., Huber, O., Nassar, J., Navarro, P. Recorriendo el paisaje vegetal en Venezuela. Ediciones IVIC, Instituto Venezolano de Investigaciones Científicas. Caracas, Venezuela. pp 173-209, 2013)
La investigación ecológica en los páramos venezolanos tiene más de 40 años de desarrollo. A partir de los trabajos pioneros durante los años setenta, se han venido consolidando una serie de líneas de investigación que han ...
Water relations and gas exchange in Coespeletia moritziana (Sch. Bip) Cuatrec., a giant rosette species of the high tropical Andes
(Photosynthetica 50: 429-436, 2012-04-26)
Giant rosettes are ones of the most striking features of the vegetation in the high tropical Andes, with Coespeletia moritziana reaching the highest altitudes up to 4,600 m a.s.l. Different from other giant rosettes, this ...
Freezing avoidance in tropical Andean bamboos
(LXth World bamboo Congress proceedings. Sección 2, Massachusetts, USA. pp. 247-257, 2012-04-15)
Frost resistance was compared in five species of different life forms in the neotropical woody bamboo genus Chusquea growing along a cloud forest-paramo gradient, between 2250-4010 m a.s.l. in the Venezuelan Andes. C. ...
Seasonal gas exchange and water relations in juveniles of two evergreen neotropical savanna tree species with contrasting regeneration strategies
(Trees 25(3): 473-483, 2011)
Colonization dynamics of woody species into
grasslands in Neotropical savannas are determined by two main factors: plant-available moisture and fire. Considering
seasonality of precipitation and high fire frequency in these ...
Leaf gas exchange in canopy species of a Venezuelan cloud forest
(Biotropica 41(6): 659-664, 2009-11)
Tropical cloud forests are considered humid ecosystems with frequent cloud cover down to the ground surface. However, seasonal variation in precipitation may induce
short-term water stress. For canopy leaves, this water ...
