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 ... -
Eficacia de diferentes formulaciones de Clonostachys rosea en el control del moho gris (Botrytis ...
(Universidad de Concepción, Facultad de Ciencias Forestales., 2015)Los aislados de Clonostachys rosea A10 y A11 han demostrado previamente su capacidad antagónica frente al patógeno Botrytis cinerea tanto en condiciones in vitro como en condiciones de campo. ... -
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 ...
