Drought stress and pests increase defoliation and mortality rates in vulnerable Abies pinsapo forests
(Forest Ecology and Management, 2022)Forest ecosystems are increasingly exposed to the combined pressure of climate change and attacks by pests and pathogens. These stress factors can threaten already vulnerable species triggering dieback and rising defoliation ... -
Early diagnosis of vegetation health from high-resolution hyperspectral and thermal imagery: lessons learned from empirical relationships and radiative transfer modelling
(Springer, 2019)Purpose of Review We provide a comprehensive review of the empirical and modelling approaches used to quantify the radiation–vegetation interactions related to vegetation temperature, leaf optical properties linked to ... -
Economic susceptibility of fire-prone landscapes in natural protected areas of the southern Andean Range
(Elsevier, 2018)Large fires are the most important disturbances at landscape-level due to their ecological and socioeconomic impacts. This study aimed to develop an approach for the assessment of the socio-economic landscape susceptibility ... -
Economic vulnerability of timber resources to forest fires
(Elsevier, 2012)The temporalespatial planning of activities for a territorial fire management program requires knowing the value of forest ecosystems. In this paper we extend to and apply the economic valuation principle to the concept ... -
Edad y clima como moduladores del crecimiento en poblaciones relícticas de Pinus nigra subsp. salzmannii en España
(Asociación Española de Ecología Terrestre, 2013) -
Efecto de distintas fertilizaciones de fósforo en la resistencia de brinzales de encina y alcornoque a "Phytophthora cinnamomi" Rands
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2004)El factor de contribución más virulento en el proceso de decaimiento forestal en el sur de la península ibérica es el Oomiceto Phytophthora cinnamomi Rands. Recientes investigaciones avalan el uso de fertilizaciones ... -
Efecto de la cobertura y de la fertilización en el desarrollo de plantas de Nothofagus alessandrii cultivadas en contenedor
(Universidad Austral de Chile, 2011)Nothofagus alessandrii is an endangered species. Yet, available information for the propagation and nursery cultivation of this species is conspicuously lacking. To this end, we studied the effect of cover and fertilization ... -
Efecto de los sistemas de riego en la rentabilidad de plantaciones de eucalipto (Eucalyptus globulus)
(Colegio de Postgraduados (México), 2010)El riego es utilizado con mayor frecuencia para establecer plantaciones, con el fin de aumentar el crecimiento y la productividad por superficie. Se estudió el efecto de tres sistemas de riego: microaspersión (T1), goteo ... -
Efecto de poda y raleo en el área foliar de Eucalyptus nitens
(Universidad Austral de Chile, 2008)Eucalyptus nitens is an important commercial fast growing species planted mainly in Chile and Australia (Tasmania). In Chile there are not previously published studies quantifying leaf area in adult forest plantations of ... -
Effect of leaves in the dynamic response of olive tree branches and their computational model
(Elsevier, 2022)The application of vibration in the mechanical harvesting of fruit trees is a determining factor to achieve fruit detachment. The acceleration required to do so is experimentally determined in expensive tests using ... -
Effects of two water regimes on morphological traits, nutritive value and physiology of three Bituminaria bituminosa varieties from the Canary Islands
(Wiley, 2021)Morphological traits, nutritive values and physiological responses to two different water regimes of three Bituminaria bituminosa varieties: var. albomarginata, var. crassiuscula and var. bituminosa were evaluated in a ... -

Estimating leaf carotenoid content in vineyards using high resolution hyperspectral imagery acquired from an unmanned aerial vehicle (UAV)
(Science Direct, 2013)Chlorophyll a+b (Ca+b) and carotenoids (Cx+c) are leaf pigments associated with photosynthesis, participation in light harvesting and energy transfer, quenching and photoprotection. This manuscript makes progress on ... -
Estimating pasture quality of Mediterranean grasslands using hyperspectral narrow bands from field spectroscopy by Random Forest and PLS regressions
(Elsevier, 2022)Mediterranean grasslands are a cornerstone ecosystem to provide ecosystem services and sustain human societies. The sustainability and provision of ecosystem services by these systems rely on their management. One of the ... -
Evaluación de la mortalidad de bosques de ñirre (Nothofagus antarctica) en la Patagonia chilena mediante imágenes Landsat TM y ETM+
(Universidad Austral de Chile, 2008)Antarctic beech forests (Nothofagus antarctica (G. Forst.) Oerst.) have shown a major decline process in the past few decades, together with an important lack of specific studies on this type of forest. The aim of this ... -
