NON-SYMBIOTIC NITROGEN FIXATION, NET NITROGEN MINERALIZATION AND DENITRIFICATION IN EVERGREEN FORESTS OF CHILOÉ ISLAND, CHILE: A COMPARISON WITH OTHER TEMPERATE FORESTS
(Facultad de Ciencias Naturales y Oceanográficas, Universidad de Concepción, 2003)
Nitrogen mineralization in two unpolluted old-growth forests of contrasting biodiversity and dynamics
Studies in unpolluted, old-growth forests in the coastal range of southern Chile (42°30′S) can provide a baseline for understanding how forest ecosystems are changing due to the acceleration of nitrogen (N) inputs that has ...
Vegetation composition, structure, and biomass of two unpolluted watersheds in the Cordillera de Piuchué, Chiloé Island, Chile
Research in pristine forests provides a necessary reference of energy and nutrient cycling in absence of anthropogenic influence. Therefore two unpolluted watersheds in the Cordillera de Piuchué of southern Chile (42°30′ ...
OLD-GROWTH TEMPERATE RAINFORESTS OF SOUTH AMERICA: CONSERVATION, PLANT–ANIMAL INTERACTIONS, AND BASELINE BIOGEOCHEMICAL PROCESSES
A structural and compositional definition of old-growth forest is presented, which places emphasis on the lack of recurrent human impact, the presence of a shade-tolerant canopy with emergent pioneers, and a patch area ...
Litterfall dynamics and nitrogen use efficiency in two evergreen temperate rainforests of southern Chile
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 ...
Species assemblages of zooplanktonic crustaceans in mountain shallow ponds of Chile (Parque Cani)
(SOC BRASILEIRA ZOOLOGIA. UNIV FEDERAL PARANA, 2010)
Successional changes in soil nitrogen availability, non-symbiotic nitrogen fixation and carbon/nitrogen ratios in southern chilean forest ecosystems
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 ...
Non-symbiotic nitrogen fixation during leaf litter decomposition in an old-growth temperate rain forest of Chiloé Island, southern Chile: Effects of single versus mixed species litter
(Ecological Society of Australia, 2010)
Heterotrophic nitrogen fixation is a key ecosystem process in unpolluted, temperate old-growth forests of southern South America as a source of new nitrogen to ecosystems. Decomposing leaf litter is an energy-rich substrate ...
