(Elsevier, 2018)The Earth surface is modulated by interactions among tectonics, climate, and biota. The influence of each of these factors on hillslope denudation rates is difficult to disentangle. The Chilean Coastal Cordillera offers a ...
-
(Cambridge University Press, 2018)We estimated visitors' willingness to pay (WTP) for a variety of environmental attributes in a protected area of the Atacama Desert, a biodiversity hotspot in northern Chile. By using a choice experiment, WTP was estimated ...
-
(Springer, 2018)The assessment of visitors’ willingness to pay (WTP) to achieve scenarios that guarantee good conservation status in protected areas and that positively contribute to visitor experience is crucial to revealing the potential ...
-
(Sociedad Chilena de la Ciencia del Suelo, 2008)El carbono orgánico del suelo (COS) se relaciona con la sustentabilidad de los sistemas agrícolas afectando las propiedades del suelo relacionadas con el rendimiento sostenido de los cultivos. El COS se vincula con la ...
-
(ELSEVIER SCIENCE BV, 2013-01)Soil management practices may change the soil properties. The magnitude of the change varies according to the soil property, the climate, and the type and time of implementation of a particular management system. The aim ...
-
(Copernicus Gesellschaft MBH, 2020)A critical aspect of predicting soil organic carbon (SOC) concentrations is the lack of available soil information; where information on soil characteristics is available, it is usually focused on regions of high agricultural ...
-
(Copernicus Gesellschaft MBH, 2020)We combine geophysical observations from ground-penetrating radar (GPR) with regolith physical and chemical properties from pedons excavated in four study areas spanning 1300 km of the climate and ecological gradient in ...

(Elsevier, 2012)We studied the effects of afforestation on soil respiration (Rs) in an arid shrubland in northern Chile. We sampled Rs monthly for three years in two adjacent plots, one left as control in natural condition, and one afforested ...

Evaluation of impacts of management in an anthropogenic peatland using field and remote sensing data (ESA, 2015)Peatlands are a type of wetland characterized by the accumulation of organic matter, called peat, and are important carbon reservoirs. In areas with poor drainage, human-induced forest fires and logging can produce flooded ...
-
(Universidad de Chile, 2011)Los suelos circundantes a la fundición de cobre de Caletones presentan altos niveles de aluminio intercambiable debido a la acidificación que han sufrido por la lluvia ácida, generada a partir de los gases emitidos por la ...
-
(Soil Science Society of America, 2014)Litter extraction (LE) is a common practice in many forests of the world. This process can cause long-term depletion of C substrates, thereby affecting ecosystem balances. The effects of LE on soil properties such as soil ...
-
(Springer, 2014)Background: Quillaja saponaria Mol., Cryptocarya alba Mol. Looser, and Lithraea caustica Molina Hook et Arn., are common sclerophyllous species in Mediterranean Central Chile. Mesophyll conductance, gm, may strongly ...
-
(ELSEVIER, 2008-05-30)This study evaluates the effect of silvicultural and exploitative interventions on soil organic carbon (SOC) in Chilean Lenga (Nothofagus pumilio (Poepp et Endl.) Krasser) forests in south Patagonia. We analyzed SOC and ...
-
(ELSEVIER SCIENCE BV, 2008-06)No-tillage systems affect soil properties depending on the soil, climate, and the time since its implementation. In heavy no-tilled soils a surface compacted layer is commonly found. Such layer can affect root growth and ...
-
(2014)Sclerophyllous shrubs and forests are predominant in semiarid Central Chile and have a long history of degradation by fire, cultivation, firewood extraction and grazing. The aim of this study was to compare the amount ...
-
(Universidad Austral de Chile, Facultad de Ciencias Forestales y Recursos Naturales, 2015)The carbon stock associated with tree biomass was estimated in evergreen forests near the town of Inío in Chiloé Island, Chile (43º21’ S, 74º07’ W), analyzing its relation with biotic and abiotic properties. A total of ...
-
(Universidad de Chile, 2008)El objetivo de este estudio fue evaluar la variación temporal de la estabilidad de los agregados de un suelo manejado con cero labranza (CL) y labranza convencional (LC). Se evaluó además la actividad microbiana del suelo. ...
