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 ...
