Ecological impacts of different harvesting scenarios for temperate evergreen rain forest in southern Chile-A simulation experiment
(Elsevier, 2007)
Current forestry practices in Chile largely rely on exotic tree plantations, and limited management experiences are available for the species-rich native evergreen rain forests. Yet, conservationists and forest scientists ...
Litterfall dynamics and nitrogen use efficiency in two evergreen temperate rainforests of southern Chile
(2003)
In unpolluted regions, where inorganic nitrogen (N) inputs from the atmosphere are minimal, such as remote locations in southern South America, litterfall dynamics and N use efficiency of tree species should be coupled to ...
Coarse woody debris stimulates soil enzymatic activity and litter decomposition in an old-growth temperate forest of Patagonia, Argentina
(Springer, 2013-04-30)
In most temperate forest ecosystems, tree mortality over time generates downed logs that accumulate as coarse woody debris (CWD) on the forest floor. These downed logs and trunks have important recognized ecosystem functions ...
Silica biogeochemical cycle in temperate ecosystems of the Pampean Plain, Argentina
(Pergamon-Elsevier Science Ltd, 2015-11)
Silicophytoliths were produced in the plant communities of the Pampean Plain during the Quaternary. The biogeochemistry of silicon is scarcely known in continental environments of Argentina. The aim of this work is to ...
Coupled biospheric synchrony of the coastal temperate ecosystem in northern Patagonia: A remote sensing analysis.
Over the last century, climate change has impacted the physiology, distribution, and phenology of marine and terrestrial primary producers worldwide. The study of these fluctuations has been hindered due to the complex ...
Ecological theory and values in the determination of conservation goals: examples from temperate regions of Germany, United States of America, and Chile
(Sociedad de Biología de Chile, 2004)
Pinus ponderosa alters nitrogen dynamics and diminishes the climate footprint in natural ecosystems of Patagonia
(Wiley, 2014-04)
1. Understanding climate effects on plant?soil interactions in terrestrial ecosystems remains challenging due to the fact that floristic composition covaries with climate, particularly along rainfall gradients. It is ...
Successional changes in soil nitrogen availability, non-symbiotic nitrogen fixation and carbon/nitrogen ratios in southern chilean forest ecosystems
(Springer, 2004)
Vast areas of southern Chile are now covered by second-growth forests because of fire and logging. To study successional patterns after moderate-intensity, anthropogenic fire disturbance, we assessed differences in soil ...
