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 ...
Low temperature resistance in saplings and ramets of Polylepis sericea in the Venezuelan Andes
(Acta Oecologica 35(5): 610–613, 2009-10)
The frequent occurrence of all year-round below zero temperatures in tropical high mountains constitutes a most stressful climatic factor that plants have to confront. Polylepis forests are found well above
the continuous ...
Functional characterisitcs of the arborescent genus Polylepis along a latitudinal gradient in the high Andes
(Interciencia 32(10): 663-668, 2007-09)
Polylepis is a genus restricted to the Andean Mountain Range, naturally occurring above the upper continuous forest limit. The purpose of this work was to integrate and compare
functional characteristics in terms of water ...
