A comparison between traditional ordinary least-squares regression and three methods for enforcing additivity in biomass equations using a sample of Pinus radiata trees
(Scion, 2020)Background: Additivity has long been recognised as a desirable property of systems of equations to predict the biomass of components and the whole tree. However, most tree biomass studies report biomass equations fitted ... -
A system to evaluate fire impacts from simulated fire behavior in Mediterranean areas of Central Chile
(Elsevier, 2017)Wildfires constitute the greatest economic disruption to Mediterranean ecosystems, from a socio-economic and ecological perspective (Molina et al., 2014). This study proposes to classify fire intensity levels based on ... -
Above-ground biomass accumulation and growth in a marginal nothofagus macrocarpa forest in Central Chile
(2010)Nothofagus macrocarpa forests are situated in the northern limit of Nothofagus genus distribution in South America. Data related to their growth conditions are insufficient. Above-ground biomass accumulation and growth ... -
Aboveground biomass estimation in intervened and non-intervened Nothofagus pumilio forests using remotely sensed data
(Taylor & Francis, 2012-06-20)Forest inventory data can be used along with remotely sensed data to estimate biomass and carbon stocks over large and inaccessible forested areas. In this study, the relationship between satellite-derived multispectral ... -
Actividad insecticida de extractos del fruto de Melia azedarach en distintos estados de madurez sobre Drosophila melanogaster
(2008)Se evaluó la actividad insecticida de extractos del fruto de Melia azedarach L. (Meliaceae) en distintos estados de madurez sobre Drosophila melanogaster Meigen (Diptera: Drosophilidae), con miras a su uso potencial en ... -
An air-drying model for piled logs of Eucalyptus globulus and Eucalyptus nitens in Chile
(Springer, 2015)Background: Water accounts for around half of the total mass in living trees, and therefore large savings can be achieved if logs are dried before transporting or burning. Methods: An air-drying model for piled logs of ... -
Analysis of within and between-GCM uncertainties of runoff projections in Mediterranean-like catchments
(Australian bureau meteorology, 2017)Streamflow reductions have been reported in mid-latitude Southern Hemisphere (SH) catchments, in particular in the southwest of Western Australia (SWA) and in central Chile (CC), following decreases in precipitation since ... -

Por una parte, se trata de estudiar los aspectos fundamentales de la teoría de las finanzas corporativas, es decir, ... -
Anthropocene and streamflow: long-term perspective of streamflow variability and water rights
(University of California, 2019)Since 1981, water allocation in Chile has been based on a water use rights (WURs) market, with limited regulatory and supervisory mechanisms. The volume to be granted as permanent and eventual WURs is calculated from ... -
Antioxidant activity of a new aromatic geranyl derivative of the resinous exudates from Heliotropium glutinosum Phil.
(2007)Heliotropium glutinosum Phil. (Heliotropiceae) is a resinous bush that grows at a height of 2000 in in Chanaral, Chile. From the resinous exudates of Heliotropium glutinosum Phil. a new aromatic geranyl derivative: ... -
Aplicación de Ondas Sónicas y Ultrasónicas como Medio de Control del Ataque de Termitas Subterráneas Reticulitermes fl avipes (Kollar) en Madera de Pino Radiata.
(UNIV BIO-BIO, WOOD ENGINEERING DEPT, 2008)The behavior of the termites was analyzed when applying sonic and Ultrasonic waves with different frequencies, levels of energy. and waveform to establish the conditions to create a physical barrier to the action of the ... -
Assessing floristic representativeness in the protected areas national system of Chile: are vegetation types a good surrogate for plant species?
(Cambridge Univ. Press, 2016)Conservation planning relies heavily on representativeness patterns. In Chile, this has not been assessed at the species level. This study evaluates floristic representativeness in the National System of Protected Areas ... -
Assessing habitat loss and fragmentation and their effects on population viability of forest specialist birds: linking biogeographical and population approaches
(Wiley, 2018-06)Aim: Biogeographic approaches usually have been developed apart from population ecology, resulting in predictive models without key parameters needed to account for reproductive and behavioural limitations on dispersal. ... -
Assessing the value of species: a case study on the willingness to pay for species protection in Chile
(Springer, 2013)We conduct a valuation of species protection in central Chile's Campana National Park (CNP) using the choice experiment (CE) method. The CNP has been recognized as having global relevance for the conservation of ... -
Assessing visitors' preferences for ecosystem features in a desert biodiversity hotspot
(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 ... -
Baseline of carbon stocks in pinus radiata and eucalyptus spp. plantations of Chile
(MDPI, 2020)Forest plantations have a large potential for carbon sequestration, playing an important role in the global carbon cycle. However, despite the large amount of research carried out worldwide, the absolute contribution of ... -
Biomass yield and quality of an energy dedicated crop of poplar (Populus spp.) clones in the Mediterranean zone of Chile
(Elsevier, 2015)The biomass of nineteen Populus spp. clones was measured and characterized as a feedstock for energy production. Biomass yield was estimated using the average volume and dry weight of each clone. Quality traits analyzed ... -
Botanical Composition and Diet Quality of the Vicuñas (Vicugna vicugna Mol.) in Highland Range of Parinacota, Chile
(MDPI, 2020)Simple Summary For the proper management of grazing wild ungulates, it is very important to know the botanical composition and quality of their selected diets. In the case of the vicuna, a wild camelid that lives in the ... -
Can conservation in protected areas and visitor preferences converge? An empirical study in Central Chile
(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 ... -
Caracterización cromosómica de Rhodolirium laetum (Phil.) Ravenna (Amaryllidaceae) a través de cariotipificación e hibridación in-situ de ADN ribosómico
