Soil enzymes associated with carbon and nitrogen cycling in invaded and native secondary forests of northwestern Argentina [PDF]

open access: yes, 2014
Background and aims: Alien success has frequently been associated with changes in the concentrations of soil nutrients. We aim to investigate the effects of plant invasion on soil nutrients, potential enzyme activity and litter elemental composition and ...

STUDIES IN MONODOMINANT FORESTS IN EASTERN MATO GROSSO, BRAZIL: II. A FOREST IN THE AREÕES XAVANTE INDIAN RESERVE

open access: yesEdinburgh Journal of Botany, 2001
The floristic composition, structure, soil fertility and leaf nutrient concentrations were analysed in a monodominant forest of Brosimum rubescens Taub. located in the Areões Xavante Indigenous Reserve (14°34′S, 51°58′W). The area lies in the ecotone between Amazonian forest and cerrado in the municipality of Água Boa, Mato Grosso State, Brazil.
