Latitudinal and altitudinal patterns of plant community diversity on mountain summits across the tropical Andes.
(Ecography 40: DOI: 10.1111/ecog.02567, 2016-11-04)
The high tropical Andes host one of the richest alpine floras of the world, with exceptionally high levels of endemism
and turnover rates. Yet, little is known about the patterns and processes that structure altitudinal ...
Facilitation and edge effects influence vegetation regeneration in old-fields at the tropical Andean forest line
(2015)
Questions: Do local plant-plant interactions and facilitation play an important role in vegetation dynamics after disturbance in the high tropical Andes? In particular, does the dominant shrub Baccharis prunifolia have an ...
Estructura, diversidad y dinámica de la vegetación en el ecotono bosque-páramo: revisión de la evidencia en la Cordillera de Mérida
(2015)
En los Andes tropicales, el límite altitudinal de los bosques corresponde a una compleja zona de transición entre el bosque paramero y el páramo andino. En el límite inferior de esta zona ocurre a su vez una transición ...
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 ...
The context-dependence of beneficiary feedback effects in plant facilitations
(New Phytologist: DOI: 10.1111/nph.12908, 2014-05-20)
Facilitative effects of some species on others are a major driver of biodiversity. These
positive effects of a benefactor on its beneficiary can result in negative feedback effects of the
beneficiary on the benefactor and ...
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 ...
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 ...
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 ...
Ecología, hidrología y suelos del páramo
(Programa de Capacitación Técnica. Proyecto Páramo Andino-CONDESAN, Quito. 272 pp., 2012-08)
