A Novel Methodology to Estimate Single-Tree Biophysical Parameters from 3D Digital Imagery Compared to Aerial Laser Scanner Data
Hernández Clemente, Rocío; Navarro Cerrillo, Rafael M.; Romero Ramírez, Francisco J.; Hornero, Alberto; Zarco-Tejada, Pablo J. (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 ... -
Assessing the contribution of understory sun-induced chlorophyll fluorescence through 3-D radiative transfer modelling and field data
Hornero, Alberto; North, P. R. J.; Zarco-Tejada, Pablo J.; Rascher, U.; Martín, M.P.; Migliavacca, M.; Hernández Clemente, Rocío (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 effects of forest health on sun-induced chlorophyll fluorescence using the FluorFLIGHT 3-D radiative transfer model to account for forest structure
Hernández Clemente, Rocío; North, P. R. J.; Hornero, Alberto; Zarco-Tejada, Pablo J. (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 ... -
Divergent abiotic spectral pathways unravel pathogen stress signals across species
Zarco-Tejada, Pablo J; Poblete, T.; Camino, C.; González-Dugo, Victoria; Calderón, R.; Hornero, Alberto; Hernández Clemente, Rocío; Román-Écija, M.; Velasco-Amo, P.; Landa, Blanca B.; Beck, P. S. A.; Saponari, M.; Boscia, D.; Navas Cortés, Juan A. (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 ... -
Early diagnosis of vegetation health from high-resolution hyperspectral and thermal imagery: lessons learned from empirical relationships and radiative transfer modelling
Hernández Clemente, Rocío; Hornero, Alberto; Möttus, Matti; Penuelas, J.; González-Dugo, Victoria; Jiménez, J. C.; Suárez, L.; Alonso, L.; Zarco-Tejada, Pablo J. (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 ... -
Global monitoring of soil multifunctionality in drylands using satellite imagery and field data
Hernández Clemente, Rocío; Hornero, Alberto; González-Dugo, Victoria; Berdugo, Miguel; Quero, José L.; Jiménez, J. C.; Maestre, Fernando T. (Zoological Society of London, 2023)Models derived from satellite image data are needed to monitor the status of terrestrial ecosystems across large spatial scales. However, a remote sensing-based approach to quantify soil multifunctionality at the global ... -
Modelling hyperspectral- and thermal-based plant traits for the early detection of Phytophthora-induced symptoms in oak decline
Hornero, Alberto; Zarco-Tejada, Pablo J.; Quero, José L.; North, P. R. J.; Ruiz-Gómez, Francisco José; Sánchez de la Cuesta, Rafael; Hernández Clemente, Rocío (Science Direct, 2021)Holm oak decline is a complex phenomenon mainly influenced by the presence of Phytophthora cinnamomi and water stress. Plant functional traits (PTs) are altered during the decline process — initially affecting the physiological ... -
Previsual symptoms of Xylella fastidiosa infection revealed in spectral plant-trait alterations
Zarco-Tejada, Pablo J.; Camino, C.; Beck, P. S. A.; Calderón, R.; Hornero, Alberto; Hernández Clemente, Rocío; Kattenborn, T.; Montes-Borrego, M.; Susca, L.; Morelli, M.; González-Dugo, Victoria; North, P. R. J.; Landa, Blanca B.; Boscia, D.; Saponari, M.; Navas Cortés, Juan A. (Nature, 2018)Plant pathogens cause significant losses to agricultural yields and increasingly threaten food security1, ecosystem integrity and societies in general2,3,4,5. Xylella fastidiosa is one of the most dangerous plant bacteria ...
