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 ...
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 ...
How do two Lupinus species respond to temperature along an altitudinal gradient in the Venezuelan Andes?
(Revista Chilena de Historia Natural 81: 335-343, 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 ...
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 ...
