Selvas y bosques nublados de Venezuela
(Medina, E., Huber, O., Nassar, J., Navarro, P. Recorriendo el paisaje vegetal en Venezuela. Ediciones IVIC, Instituto Venezolano de Investigaciones Científicas. Caracas, Venezuela. pp. 125-155, 2013)
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 ...
Aspectos ecofisiológicos del establecimiento de dos especies de árboles siempreverdes de las sabanas estacionales
(2012-06-26)
El patrón espacial y la abundancia relativa de gramíneas y árboles en las sabanas están
determinados por interacciones complejas y dinámicas entre el clima, la topografía, los
suelos, la geomorfología, la ...
Microclimate and regeneration patterns of Polylepis Sericea in a treeline forest of the Venezuelan Andes
(SABER-ULA, 2011-06)
Tropical high mountains constitute environments where harsh conditions prevail. Polylepis forests are found above the continuous forest line throughout the Andes, with P. sericea as the only species in Venezuela. Sprouting ...
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 ...
