Comparing Generalized Linear Models and random forest to model vascular plant species richness using ...
(Elsevier, 2016)Biodiversity is considered to be an essential element of the Earth system, driving important ecosystem services. However, the conservation of biodiversity in a quickly changing world is a ... -
Consideraciones sobre la sistemática de las familias y los géneros de plantas vasculares endémicos de Chile
(Ediciones Universitarias, 2015)Endemism is one of the main considerations in historical biogeography and one of the most important criteria when establishing conservation priorities. Worldwide, more than 90% of the plants ... -
The physiological and growth response of Acacia caven under water stress and the application of different ...
(PUC, 2015)Acacia caven (Mol.) Mol. (Leguminosae), generally known as "espino," is one of the most common tree species in the Mediterranean region of Chile. This species grows in nutritionally poor soils ... -
Diagrama de manejo de la densidad de rodal para el control del tamaño de ramas basales en bosques ...
(Universidad de Chile, Facultad de Ciencias Forestales y de la Conservación de la Naturaleza, 2015)Con el objetivo de construir un modelo de manejo para el autocontrol del tamaño de las ramas en las trozas basales de renovales dominados por Nothofagus obliqua (roble) que crecen en la ... -
Comparative leaf anatomy and micromorphology of the Chilean Myrtaceae: Taxonomic and ecological implications
(Elsevier, 2015)The family Myrtaceae in Chile comprises 26 species in 10 genera. The species occur in a diverse range of environments including humid temperate forests, swamps, riparian habitats and coastal ... -
Influence of thinning over growth, water potential and photosynthetic response of Peumus boldus: ...
(Univ Austral Chile, Fac Ciencias Forestales, 2015)Peumus boldus, an endemic tree species of central Chile, belongs to sclerophyllous forests. Its semi-xerophytes condition allows it to grow in places with low rainfall and poor soils. The ... -
Crown size and growing space requirement of common tree species inurban centres, parks, and forests
(Elsevier, 2015)Tree crown size determines among others tree’s growth, carbon sequestration, shading, filtering of fineair particulates, and risk of wind-breaking. The dependence of crown size on species, ... -
Does Environmental Heterogeneity Promote Cognitive Abilities?
(Elsevier, 2015)In the context of global change the possible loss of biodiversity has been identified as a major concern. Biodiversity could be seriously threatened as a direct consequence of changes in ... -
La comunidad de Mata de Limón, Pacífico central de Costa Rica y la extracción de colonchos Callichirus ...
(Univ Católica de Valparaíso, 2015)En el presente estudio, se realizaron visitas mensuales a la comunidad de Mata de Limón (diciembre 2011 a noviembre 2012) localizada en el Pacífico central de Costa Rica para evaluar una serie ... -
Quantitative analysis of forest fire extinction efficiency
(INIA, 2015)Aim of study: Evaluate the economic extinction efficiency of forest fires, based on the study of fire combat undertaken by aerial and terrestrial means. Area of study, materials and methods: ... -
Recruitment Dynamics of the Relict Palm, Jubaea chilensis: Intricate and Pervasive Effects of Invasive ...
(Public Library Science, 2015)Shrubs can have a net positive effect on the recruitment of other species, especially relict species in dry-stressful conditions. We tested the effects of nurse shrubs and herbivory defoliation ... -
Leaf micromorphology and anatomy of Myrceugenia rufa (Myrtaceae). An endemic coastal shrub of north-central ...
(Facultad de Ciencias Naturales y Oceanográficas, Universidad de Concepción, 2015)Species of fleshy-fruited Myrtaceae are generally associated with humid environments and their vegetative anatomy is mainly mesophytic. Myrceugenia rufa is an endemic and rare species from ... -
Determining response times for the deployment of terrestrial resources for fighting forest fires. A ...
(PUC, 2015)A study of response times for the arrival of terrestrial forest fire fighting resources was undertaken. The advantage of the method proposed here is that it may be exactly replicated in different ... -
Modeling forest biomass using Very-High-Resolution data - Combining textural, spectral and photogrammetric ...
(Italian Society of Remote Sensing, 2015)We used spectral, textural and photogrammetric information from very-high resolution (VHR) stereo satellite data (Pleiades and WorldView-2) to estimate forest biomass across two test sites ... -
Seedling fate across different habitats: The effects of herbivory and soil fertility
(ELSEVIER, 2015)The impact of extinction of predators and subsequent herbivore release on ecosystem functioning has been well studied in temperate ecosystems, yet we have very little information on threatened ... -
Comparison of Airborne LiDAR and Satellite Hyperspectral Remote Sensing to Estimate Vascular Plant ...
(MDPI AG, 2015)The Andes foothills of central Chile are characterized by high levels of floristic diversity in a scenario, which offers little protection by public protected areas. Knowledge of the spatial ... -
Biomass yield and quality of an energy dedicated crop of poplar (Populus spp.) clones in the Mediterranean ...
(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 ... -
Effect of Clearcutting Operations on the Survival Rate of a Small Mammal
(Cross Mark, 2015)Clearcutting is a common timber harvesting technique that represents a significant and abrupt change in habitat conditions for wildlife living in industrial forests. Most research on this type ... -
Stratified aboveground forest biomass estimation by remote sensing data
(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 ... -
Maintenance of Genetic Diversity in an Introduced Island Population of Guanacos after Seven Decades ...
(2014)Fifteen guanacos were introduced to Staats Island in the Falklands/Malvinas archipelago from Patagonia in the 1930s. Twenty five years later, the population was culled from 300 to 10–20 ...
