Spatial relations and population structure of a dominant tree along a treeline ecotone in the Tropical Andes: interactions at gradient and plant-neighbourhood scales
(Plant Ecology and Diversity 6(3-4): 343-353, 2013)
Background: Studies in temperate mountains suggest that plant-plant interactions
modulate tree establishment above the forest line. In tropical mountains worldwide this
issue remains largely unexplored.
Aims: To analyse ...
Modelling competitive ability of neotropical savanna grasses: Simulation of shading and drought impacts on biomass production
(Ecological Informatis 13: 57-69, 2013)
In this paper, we develop a technique to model the spatial distribution of shoots along vertical and horizontal
dimensions of a plant community. We use it to simulate the growth of a tropical savanna near the city of ...

Community impacts of Prosopis juliflora Iivasion: biogeographic and congeneric comparisons
(Plos ONE 7(9):e44966. 1-13, 2012-09-12)
We coordinated biogeographical comparisons of the impacts of an exotic invasive tree in its native and non-native ranges with a congeneric comparison in the non-native range. Prosopis juliflora is taxonomically complicated ...

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 ...
Leaf spectra and weight of species in canopy, sub-canopy, and understory layers in a Venezuelan Andean cloud forest
(Scientifica, Article ID 839584, 14 pages http://dx.doi.org/10.6064/2012/839584, 2012-04-22)
We characterize the leaf spectra of tree species of an Andean cloud forest in Venezuela, grouped according to position in canopy, subcanopy and understory. We measured leaf reflectance and transmittance spectra in the ...
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. ...
