(Univ. Pinar Rio Hermanos Saiz Montes Oca, 2020)The production of poles in Chile is done by choosing trees specially selected for that purpose, however, the forestry that is massively applied is oriented to the simultaneous production of pruned, sawn and pulpable logs. ...
-
(SCION, 2022)Background: South America has the largest area of temperate forests in the Southern Hemisphere, which grow in diverse site conditions. The aim of this paper is to review the practices of silviculture applied and recommended ...
-
(MDPI, 2020)Mediterranean cultural landscapes have been recognized as multifunctional landscapes that are currently threatened by two opposing trends: rural abandonment and agricultural intensification. Uncovering people's perceptions ...
-
(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 ...
-
(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 ...
-
(MDPI, 2018)This study aims to determine if there is variation in precipitation concentrations in Chile. We analyzed daily and monthly records from 89 pluviometric stations in the period 1970-2016 and distributed between 29 degrees ...
-
(Wiley, 2021)To better identify biodiversity hotspots for conservation on Hainan Island, a tropical island in southern China, we assessed spatial variation in phylogenetic diversity and species richness using 18,976 georeferenced ...
-
(Elsevier, 2017)Current geographic patterns of biodiversity are a consequence of the evolutionary history of the lineages that comprise them. This study was aimed at exploring how evolutionary features of the vascular flora of Chile are ...

Spatio-Temporal Changes in Structure for a Mediterranean Urban Forest: Santiago, Chile 2002 to 2014 (MDPI, 2016)There is little information on how urban forest ecosystems in South America and Mediterranean climates change across both space and time. This study statistically and spatially analyzed the spatio-temporal dynamics of ...

(Springer, 2018)In most conservation programs that include public participation, the word "biodiversity" is used. However, many variables influence the public understanding of the term and determine what biodiversity means to local ...
-
(Pontificia Universidad Católica de Chile. Facultad de Agronomía Ingeniería Forestal, 2016)Stem CO2 efflux is a highly variable component of the carbon budget of forest ecosystems. It reflects the balance between the CO2 respired by the living stem tissues, less the CO2 dissolved in the xylem sap moving upward ...
-
(Elsevier, 2015)Remote sensing-assisted estimates of aboveground forest biomass are essential for modeling carbon budgets. It has been suggested that estimates can be improved by building species- or strata-specific biomass models. ...
-
(COLEGIO DE POSTGRADUADOS, 2008-05)In Chile, the Australian weevil Gonipterus scutellatus Gyllenhal (Coleoptera: Curculionidae), specific to eucalyptus, was first detected in 1998. It has spread trough the IV to IX Regions and could affect more than 525 ...

Systematics, taxonomy and domestication of alpaca and llama: new chromosomal and molecular evidence (2007)Four camelid species exist in South America: two wild, the guanaco (Lama guanicoe) and the vicuna (Victigna vicugna), and two domestic, the alpaca (Lama pacos) and the llama (Lama glama). However, the origin of the domestic ...
