Branch xylem density variations across the Amazon Basin
(Copernicus Publications, 2009)
Xylem density is a physical property of wood that varies between individuals, species and environments. It reflects the physiological strategies of trees that lead to growth, survival and reproduction. Measurements of ...
Above- and below-ground net primary productivity across ten Amazonian forests on contrasting soils
(Copernicus Publications, 2009)
The net primary productivity (NPP) of tropical forests is one of the most important and least quantified components of the global carbon cycle. Most relevant studies have focused particularly on the quantification of the ...
Diálogo de saberes y meta-saberes del diálogo: una perspectiva amazónica
(Universidad del Cauca, 2008)
Hacemos una reflexión crítica sobre la noción de diálogo de saberes, a partir de nuestra experiencia en un proyecto conjunto sobre frutales oleaginosos entre la Universidad Nacional de Colombia y una comunidad uitoto del ...
Fine root dynamics for forests on contrasting soils in the Colombian Amazon
(Copernicus Publications, 2009)
It has been hypothesized that as soil fertility increases, the amount of carbon allocated to below-ground production (fine roots) should decrease. To evaluate this hypothesis, we measured the standing crop fine root mass ...
Regional and large-scale patterns in Amazon forest structure and function are mediated by variations in soil physical and chemical properties
(Copernicus Publications, 2009)
Forest structure and dynamics have been noted to vary across the Amazon Basin in an east-west gradient in a pattern which coincides with variations in soil fertility and geology. This has resulted in the hypothesis that ...
Pueblos indígenas y cambio climático: el caso de la Amazonía colombiana
(2009)
Este artículo analiza las percepciones de los pueblos indígenas de la Amazonía colombiana acerca de los cambios climáticos ocurridos durante los últimos 10 años y los efectos directos sobre sus modos de subsistencia. En ...
