Evaluating models to assess the distribution of Buxus balearica in southern Spain
(Wiley, 2010)
uestion: Which is the best model to predict the habitat distribution of Buxus balearica Lam. in southern Spain?
Location: Málaga and Granada, Spain, across an area of 38 180 km2.
Methods: Prediction models based on ...
Monitoring post-fire regeneration in Mediterranean ecosystems by employing multitemporal satellite imagery
(CSIRO PUBLISHING, 2009)
Fire-damaged ecosystems have often been monitored by applying a combination of field survey information and vegetation indices derived from remotely sensed data. Furthermore, it has been demonstrated that remotely sensed ...
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. ...
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 ...
Hyperspectral and multispectral satellite sensors for mapping chlorophyll content in a Mediterranean Pinus sylvestris L. plantation
(Science Direct, 2014)
A new generation of narrow-band hyperspectral remote sensing data offers an alternative to broad-band multispectral data for the estimation of vegetation chlorophyll content. This paper examines the potential of some of ...
Semi-automated stand delineation in Mediterranean Pinus sylvestris plantations through segmentation of LiDAR data: the influence of pulse density
(Science Direct, 2017)
Traditionally, forest-stand delineation has been assessed based on orthophotography. The application of LiDAR has improved forest management by providing high-spatial-resolution data on the vertical structure of the forest. ...
Tracking the seasonal dynamics of boreal forest photosynthesis using EO-1 hyperion reflectance: sensitivity to structural and illumination effects
(IEEE, 2016)
During the growing season, the photosynthesis and growth of boreal forests are regulated by physiological responses to environmental factors. Physiological variations affect the spectral properties of leaves. Linking ...
Previsual symptoms of Xylella fastidiosa infection revealed in spectral plant-trait alterations
(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 ...
Modelling hyperspectral- and thermal-based plant traits for the early detection of Phytophthora-induced symptoms in oak decline
(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 ...
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 ...
