Gestión selvícola y regeneración natural ante un futuro incierto: marco teórico y principios generales
(Sociedad Española de Ciencias Forestales, 2014)Desde hace algunas décadas los bosques ibéricos están sujetos a un importante proceso de cambio, moti-vado por un conjunto de razones de índole ambiental y socio-económico. Ante este contexto de creciente in-certidumbre ... -
Growth and yield of mixed versus pure stands of Scots pine (Pinus sylvestris L. ) and European beech (Fagus sylvatica L.) analysed along a productivity gradient through Europe
(Springer, 2015)Mixing of complementary tree species may increase stand productivity, mitigate the effects of drought and other risks, and pave the way to forest production systems which may be more resource-use efficient and stable in ... -
Diaphragm valve hydraulic behavior depending on operating pressure
(American Society of Civil Engineers (ASCE), 2019-08-19)In this study, a hydraulically operated and diaphragm-actuated type of diaphragm valve using an elastic diaphragm was tested. With this type of valve, the opening fraction depends on the pipeline pressure; thus, it is ... -
Assessment of spray drift potential reduction for hollow-cone nozzles: Part 1. Classification using indirect methods
(Elsevier B.V., 2019-06-10)Spray drift is one of the main pollution sources identified when pesticides are sprayed on crops. In this work, in order to simplify the evaluation of hollow-cone nozzles according to their drift potential reduction, several ... -
Assessing ranked set sampling and ancillary data to improve fruit load estimates in peach orchards
(Elsevier, 2019-08-08)Fruit load estimation at plot level before harvest is a key issue in fruit growing. To face this challenge, two sampling methods to estimate fruit load in a peach tree orchard were compared: simple random sampling (SRS) ... -
Variable rate dosing in precision viticulture: Use of electronic devices to improve application efficiency
(Elsevier, 2010-03)Two different spray application methods were compared in three vine varieties at different crop stages. A conventional spray application with a constant volume rate per unit ground area (1 ha(-1)) was compared with a ... -
Spatial variability in commercial orange groves. Part 2: relating canopy geometry to soil attributes and historical yield
(Springer, 2018-10-16)Site-specific management strategies are usually dependant on the understanding of the underlying cause and effect relationships that occur at the within-field level. The assessment of canopy geometry of tree crops has been ... -
Spatial variability in commercial orange groves. Part 1: canopy volume and height
(Springer, 2018-09-22)Characterizing crop spatial variability is crucial for estimating the opportunities for site-specific management practices. In the context of tree crops, ranging sensor technology has been developed to assess tree canopy ... -
Wind and snow damage in the Pyrenees pine forests: effect of stand attributes and location
(Finnish Society of Forest Science, 2010)Wind and snow-induced damage have been analyzed at stand level for three pine forests in the Central-Eastern Pyrenees (Pinus nigra Arn. salzmanii, Pinus sylvestris L. and Pinus uncinataRam.). Stand-level models have been ... -
Species proportions by area in mixtures of Scots pine (Pinus sylvestris L.) and European beech (Fagus sylvatica L.)
(Springer, 2016)Scots pine (Pinus sylvestris L.) and European beech (Fagus sylvatica L.) dominate many of the European forest stands. Also, mixtures of European beech and Scots pine more or less occur over all European countries, but have ... -
Ús de dades de teledetecció per a la definició i mapificació de tipologies de regeneració en zones afectades per grans incendis forestals
(Centre de la Propietat Forestal, 2015) -
KFuji RGB-DS database: Fuji apple multi-modal images for fruit detection with color, depth and range-corrected IR data
(Elsevier Inc., 2019-07-19)This article contains data related to the research article entitle 'Multi-modal Deep Learning for Fruit Detection Using RGB-D Cameras and their Radiometric Capabilities' [1]. The development of reliable fruit detection and ... -
Resistance, resilience or change: post-disturbance dynamics of boreal forests after insect outbreaks
(Springer, 2019)Understanding and measuring forest resistance and resilience have emerged as key priorities in ecology and management, particularly to maintain forest functioning. The analysis of the factors involved in a forest’s ability ... -
Assessment of spray drift potential reduction for hollow-cone nozzles: Part 2. LiDAR technique
(Elsevier B.V., 2019-06-11)Pesticide spray drift poses health hazards to humans and causes a significant impact on the environment. In this work the capacity of an ad hoc light detection and ranging (LiDAR) system to differentiate spray nozzles ... -
Multi-modal deep learning for Fuji apple detection using RGB-D cameras and their radiometric capabilities
(Elsevier, 2019-05-10)Fruit detection and localization will be essential for future agronomic management of fruit crops, with applications in yield prediction, yield mapping and automated harvesting. RGB-D cameras are promising sensors for fruit ... -
Tree light capture and spatial variability of understory light increase with species mixing and tree size heterogeneity
(NRC Research Press, 2016)Mixed and multi-layered forest ecosystems are sometimes more productive than monospecific and single-layered ones. It has been suggested that trees of different species and sizes occupy complementary positions in space, ... -
Unraveling the role of light and biotic interactions on seedling performance of four Pyrenean species along environmental gradients
(Elsevier, 2013)The predicted upward displacement of forest species due to climate warming is expected to be modulated by a medley of abiotic and biotic factors acting at microsite level. Species-specific differences in plant responses ... -
Understory light predictions in mixed conifer mountain forests: Role of aspect-induced variation in crown geometry and openness
(Elsevier, 2012)Predicting light availability in forest understory is a key step in the modeling of forest dynamics. Aspect is often the main source of environmental variation in mountain forests, and so aspect-induced differences in crown ... -
Lessons learned from arson wildfire incidence in reforestations and natural stands in Spain
(MDPI, 2019-03-05)Wildfires are currently considered the major threat to forests in Mediterranean countries. It has been implied that a large percentage of arson-caused fires in Spain are connected with the extensive reforestation programs ...
