(Asociación Española de Ecología Terrestre, 2013) -
Deficiencias minerales en plantas de una savia de dos especies frondosas mediterráneas (Quercus suber L. y Ceratonia siliqua L.)
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2003) -
Deficiencias nutritivas en plantas de una savia de tres especies del género Pinus sp. en cultivo hidropónico.
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2001)El objeto del presente trabajo es el estudio de los efectos de las deficiencias de nitrógeno, fósforo, potasio y hierro en tres especies de pinos mediterráneos: Pinus pinaster Ait., Pinus pinea L. y Pinus halepensis Mill. ... -
Deforestation and Biomass Production in Miombo Forest in Huambo (Angola): A Balance between Local and Global Needs
(MDPI, 2021)Miombo is one of the most widely distributed ecosystems in Angola, with a great social and environmental value. Thus, the rural population uses the biomass as fuel and miombo provides important ecosystem services, such as ... -
Deriving predictive relationships of carotenoid content at the canopy level in a conifer forest using hyperspectral imagery and model simulation
(IEEE, 2014)Recent studies have demonstrated that the R570/R515 index is highly sensitive to carotenoid (Cx + c) content in conifer forest canopies and is scarcely influenced by structural effects. However, validated methods for the ... -
Diagrama de manejo de densidad y su aplicación a raleo en bosques de segundo crecimiento de Drimys winteri en el sur de Chile
(Universidad Austral de Chile, 2011)Stand density management (DMD) diagrams are graphical models of uniform stands at different ages that reflect the relationship among size, density, competition, site occupancy and self thinning. DMDs allow planning of ... -
Differences in the Response to Acute Drought and Phytophthora cinnamomi Rands Infection in Quercus ilex L. Seedlings
(MDPI, 2018)The sustainability of “dehesas” is threatened by the Holm oak decline. It is thought that the effects of root rot on plant physiology vary depending on external stress factors. Plant growth and biomass allocation are ... -
Discriminación de bosques de Araucaria araucana en el Parque Nacional Conguillío, centro-sur de Chile, mediante datos Landsat TM
(Universidad Austral de Chile, 2011)Araucaria forests (Araucaria araucana) have a tremendous ecological relevance; however, the information concerning their spatial distribution is still insufficient. They have only been classified according to small management ... -
Diseño, instalación y aplicación de la herramienta Marteloscopio para el entrenamiento práctico y la incorporación efectiva de valores económicos, ecológicos y sociológicos a los tratamientos selvícolas en monte
(UCOPress, 2018)Un Marteloscopio es una herramienta didáctica para el entrenamiento selvícola (ejercicios virtuales de selección de árboles). La disponibilidad de los datos del rodal forestal en un dispositivo móvil (tablet) en combinación ... -
Distribution and Factors Influencing Organic Carbon Stock in Mountain Soils in Babia Góra National Park, Poland
(MDPI, 2019)The objective of this study was to determine the soil organic carbon stock (T-SOC stock) in different mountain soils in the Babia Góra National Park (BNP). Environmental factors, such as the topography, parent material, ... -
Divergent abiotic spectral pathways unravel pathogen stress signals across species
(Springer Nature, 2021)Plant pathogens pose increasing threats to global food security, causing yield losses that exceed 30% in food-deficit regions. Xylella fastidiosa (Xf) represents the major transboundary plant pest and one of the world’s ... -
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 ... -
