2-DE proteomics analysis of drought treated seedlings of Quercus ilex supports a root active strategy for metabolic adaptation in response to water shortage
(Frontiers Media, 2015)Holm oak is a dominant tree in the western Mediterranean region. Despite being well adapted to dry hot climate, drought is the main cause of mortality post-transplanting in reforestation programs. An active response to ... -
A Farmer’s Perspective on the Relevance of Grassland-Related Innovations in Mediterranean Dehesa Systems
(MDPI, 2022)Grasslands are of key importance for the provision of ecosystem services (ES). Suitable management is essential to guarantee their persistence and functionality. There is a growing interest in innovations such as new ... -
A methodology for determining operational priorities for prevention and suppression of wildland fires
(CSIRO, 2014)Traditional uses of the forest (timber, forage) have been giving way to other uses more in demand (recreation, ecosystem services). An observable consequence of this process of forest land use conversion is an increase in ... -
A Novel Methodology to Estimate Single-Tree Biophysical Parameters from 3D Digital Imagery Compared to Aerial Laser Scanner Data
(MDPI, 2014)Airborne laser scanner (ALS) data provide an enhanced capability to remotely map two key variables in forestry: leaf area index (LAI) and tree height (H). Nevertheless, the cost, complexity and accessibility of this ... -
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 ... -
Aboveground biomass in Prosopis pallida (Humb. and Bonpl. ex Willd.) H. B. K. ecosystems using Landsat 7 ETM+ images
(Sociedad de Biología de Chile (Santiago), 2007)The significance of field work in remote sensing studies when applied to large areas has often been underestimated. The combination of specific forest inventories for the estimation of aboveground biomass in large dry ... -
Airborne Laser Scanning Cartography of On-Site Carbon Stocks as a Basis for the Silviculture of Pinus Halepensis Plantations
(MDPI, 2018)Forest managers are interested in forest-monitoring strategies using low density Airborne Laser Scanning (ALS). However, little research has used ALS to estimate soil organic carbon (SOC) as a criterion for operational ... -
An automatic trunk-detection system for intensive olive harvesting with trunk shaker.
(Elsevier, 2018)Trunk shakers are widely used for olive harvesting, being the main detachment system for fruit harvesting. In recent decades, the components of trunk shakers have evolved at mechanical, hydraulic and control levels. ... -
An ecophysiographic approach for Araucaria araucana regeneration management
(Pontificia Universidad Católica de Chile, 2012)Chilean temperate forests are dominated by Nothofagus and Araucaria araucana species. Despite A. araucana not being at imminent risk of extinction, its cultural value and the associated environmental services and landscape ... -
Analysis of postfire vegetation dynamics of Mediterranean shrub species based on terrestrial and NDVI data
(SpringerLink, 2009)The present study offers an analysis of regeneration patterns and diversity dynamics after a wildfire, which occurred in 1993 and affected about 7000 ha in southern Spain. The aim of the work was to analyze the rule in the ... -
Analysis of Site-dependent Pinus halepensis Mill. Defoliation Caused by ‘Candidatus Phytoplasma pini’ through Shape Selection in Landsat Time Series
(MDPI, 2019)High levels of ‘Candidatus Phytoplasma pini’ have produced extensive forest mortality on Pinus halepensis Mill forests in eastern Spain. This has led to the widespread levels of forest mortality. We used archival Landsat ... -
Archaeological, Palynological and Geological Contributions to Landscape Reconstruction in the Alluvial Plain of the Guadalquivir River at San Bernardo, Sevilla (Spain)
(Elsevier, 1998)Archaeological, palynological and geological studies carried out in the San Bernardo district (Sevilla) allowed us to reconstruct the changes that have taken place in vegetation and landscape relief over the areas studied. ... -
Aridity gradients shape intraspecific variability of morphological traits in native Ceratonia siliqua L. of Morocco
(MDPI, 2023)The carob tree (Ceratonia siliqua L.) is a significant fruit tree in the Mediterranean region with cultural, biological, and ecological importance. Despite its importance, intraspecific trait variability (ITV) in carob ... -
Aridity Modulates N Availability in Arid and Semiarid Mediterranean Grasslands
(Public Library of Science, 2013)While much is known about the factors that control each component of the terrestrial nitrogen (N) cycle, it is less clear how these factors affect total N availability, the sum of organic and inorganic forms potentially ... -
Assessing structural effects on PRI for stress detection in conifer forests
(Science Direct, 2011)The retrieval of indicators of vegetation stress from remote sensing imagery is an important issue for the accurate assessment of forest decline. The Photochemical Reflectance Index (PRI) has been demonstrated as a ... -
Assessing the contribution of understory sun-induced chlorophyll fluorescence through 3-D radiative transfer modelling and field data
(Science Direct, 2021)A major international effort has been made to monitor sun-induced chlorophyll fluorescence (SIF) from space as a proxy for the photosynthetic activity of terrestrial vegetation. However, the effect of spatial heterogeneity ... -
Assessing the Crop-Water Status in Almond (Prunus dulcis Mill.) Trees via Thermal Imaging Camera Connected to Smartphone
(MDPI, 2018)Different tools are being implemented in order to improve the water management in agricultural irrigated areas of semiarid environments. Thermography has been progressively introduced as a promising technique for irrigation ... -
Assessing the effects of forest health on sun-induced chlorophyll fluorescence using the FluorFLIGHT 3-D radiative transfer model to account for forest structure
(Science Direct, 2017)Sun-induced fluorescence (SIF) has been proven to serve as a proxy of photosynthesis activity and therefore, as an early indicator of physiological alterations for global monitoring of vegetation. However, the interpretation ... -
Assessing the spatiotemporal patterns and impacts of droughts in the Orinoco river basin using earth observations data and surface observations
(MDPI, 2023)Droughts impact the water cycle, ecological balance, and socio-economic development in various regions around the world. The Orinoco River Basin is a region highly susceptible to droughts. The basin supports diverse ... -
