The influence of land-use change on the organic carbon distribution and microbial respiration in a volcanic soil of the Chilean Patagonia.
Abstract Land-use changes can modify soil carbon contents. Depending on the rate of soil organic matter (SOM) formation and decomposition, soil-vegetation systems can be a source or sink of CO 2 .… Expand

No information is available about carbon (C) sequestration potentials in ecosystems on Andisols of the Chilean Patagonia. This study was undertaken to measure the size of C stocks in three… Expand
Carbon Sequestration Potential of Silvopastoral and Other Land Use Systems in the Chilean Patagonia
This study was undertaken to quantify the carbon (C) sequestration potentials in three predominant ecosystems on the volcanic soils in Patagonia, Chile. The systems were: Pinus ponderosa Dougl. ex P.… Expand
The influence of thinning and tree size on the sapwood area / leaf area ratio in coigue
The effect of thinning and crown class on the projected leaf area, specific leaf area, and projected leaf area / sapwood area ratio was evaluated in a 48-year-old even-aged stand of coigue (Nothofa...
Estimating the bioenergy potential of Pinus radiata plantations in Chile.
E. Acuna, M. Espinosa, J. Cancino, R. Rubilar, and F. Munoz. 2010. Estimating the bioenergy potential of Pinus radiata plantations in Chile. Cien. Inv. Agr. 37(1): 93– 102. The bioenergy potential… Expand
A process-based model to evaluate site quality for Eucalyptus nitens in the Bio-Bio Region of Chile
In a particular region, potential site productivity, expressed as wood production, is linearly related to leaf area index (LAI), a variable that expresses the amount of foliar surface available for… Expand
Analysis of productivity of radiata pine plantations under different silvicultural regimes using the 3-PG process-based model
Summary The effects of crown structure and management of site resources on production of wood were studied. Growth and development of three stands with agroforestry management were compared with a… Expand
Selected carbon fluxes in Pinus ponderosa-based silvopastoral systems, exotic plantations and natural pastures on volcanic soils in the Chilean Patagonia
This study was undertaken to measure certain carbon (C) fluxes in a Pinus ponderosa-based silvopastoral systems (SPS) in Patagonia, Chile. Results are compared to those from adjacent 18-year-old… Expand
The effect of pruning and thinning on above ground aerial biomass of Eucalyptus nitens (Deane & Maiden) Maiden
The effects of pruning and thinning treatments, applied at age 6 years, on the growth and aboveground biomass accumulation of a 15-year-old E. nitens plantation located in the coastal Arauco-Central Chile, suggest a negative effect of stocking on live crown length. Expand
Needle mass, fine root and stem wood production in response to silvicultural treatment, tree size and competitive status in radiata pine stands
It is concluded that foliage mass was not affected by the silvicultural treatment, tree size or competitive status, andFine root biomass showed an inverse relationship with fertilization, and greater stem wood allocation recorded in the agroforestry treatment is interpreted as a response to two different types of competition.
