Combining aerial LiDAR and multispectral imagery to assess postfire regeneration types in a Mediterranean forest
(NRC Research Press (Canadian Science Publishing), 2015-02-26)Wildfires play a major role in driving vegetation changes and can cause important environmental and economic losses in Mediterranean forests, especially where the dominant species lacks efficient postfire regeneration ... -
Spatially variable pesticide application in vineyards: Part I, developing a geostatistical approach
(ElsevierAcademic Press, 2020-05-18)A geostatistical methodology is presented to optimise the dosage of plant protection products (PPP) in vineyards with spatial variability. Sprayers are commonly used in viticulture to apply a constant volume rate per unit ... -
Fuji-SfM dataset: A collection of annotated images and point clouds for Fuji apple detection and location using structure-from-motion photogrammetry
(Elsevier, 2020)The present dataset contains colour images acquired in a commercial Fuji apple orchard (Malus domestica Borkh. cv. Fuji) to reconstruct the 3D model of 11 trees by using structure-from-motion (SfM) photogrammetry. The data ... -
History matters: previous land use changes determine post-fire vegetation recovery in forested Mediterranean landscapes
(Elsevier, 2012-06-23)Land use changes and shifts in disturbance regimes (e.g. wildfires) are recognized worldwide as two of the major drivers of the current global change in terrestrial ecosystems. We expect that, in areas with large-scale ... -
Mixing of Scots pine (Pinus sylvestris L.) and European beech (Fagus sylvatica L.) enhances structural heterogeneity, and the effect increases with water availability
(Elsevier, 2016-04-27)The mixing of tree species with complementary ecological traits may modify forest functioning regarding productivity, stability, or resilience against disturbances. This may be achieved by a higher heterogeneity in stand ... -
The role of below-ground competition during early stages of secondary succession: the case of 3-year-old Scots pine (Pinus sylvestris L.) seedlings in an abandoned grassland
(Springer Nature, 2006-02-18)In abandoned or extensively managed grasslands, the mechanisms involved in pioneer tree species success are not fully explained. Resource competition among plants and microclimate modifications have been emphasised as ... -
Climate change could negate positive tree diversity effects on forest productivity: a study across five climate types in Spain and Canada
(Springer Nature, 2017-10-17)A positive relationship between tree diversity and forest productivity is reported for many forested biomes of the world. However, whether tree diversity is able to increase the stability of forest growth to changes in ... -
Valuing acorn dispersal and resprouting capacity ecological functions to ensure Mediterranean forest resilience after fire
(Springer Nature, 2011-08-21)Ecological processes within forests provide vital ecosystem services to society, most of which depend on the persistence of tree cover that can be altered after the impact of a disturbance. The aim of the present study was ... -
The use of scenarios and models to evaluate the future of nature values and ecosystem services in Mediterranean forests
(Springer Nature, 2018-09-07)Science and society are increasingly interested in predicting the effects of global change and socio-economic development on natural systems, to ensure maintenance of both ecosystems and human well-being. The Intergovernmental ... -
Stand-level drivers of tree-species diversification in Mediterranean pine forests after abandonment of traditional practices
(Elsevier, 2015-06-03)The progressive abandonment of traditional forest management over the last few decades has led to significant densification processes in most Mediterranean pine stands. In parallel, some of these stands have also shown ... -
Unraveling the relative importance of factors driving post-fire regeneration trajectories in non-serotinous Pinus nigra forests
(Elsevier, 2015-11-14)In the Mediterranean, non-serotinous pinewoods are suffering an increasing occurrence of high-severity crown fires that usually drive vegetation shifts to fire-adapted communities and a decrease in pine-dominated area. ... -
Different factors for different causes: analysis of the spatial aggregations of fire ignitions in Catalonia (Spain)
(John Wiley and Sons, 2015-03-03)The present study analyzes the effects of different socioeconomic factors on the frequency of fire ignition occurrence, according to different original causes. The data include a set of documented ignition points in the ... -
Effects of crown architecture and stand structure on light absorption in mixed and monospecific Fagus sylvatica and Pinus sylvestris forests along a productivity and climate gradient through Europe
(John Wiley and Sons, 2017-04-29)1. When tree‐species mixtures are more productive than monocultures, higher light absorption is often suggested as a cause. However, few studies have quantified this effect and even fewer have examined which light‐related ... -
Nitrogen forms affect root structure and water uptake in the hybrid poplar
(Springer Nature, 2011-03-02)The study analyses the effects of two different forms of nitrogen fertilisation (nitrate and ammonium) on root structure and water uptake of two hybrid poplar (Populus maximowiczii x P. balsamifera) clones in a field ... -
Contrasting patterns of tree species mixture effects on wood δ13C along an environmental gradient
(Springer Nature, 2019-09-06)Establishing mixed-species stands is frequently proposed as a strategy to adapt forests to the increasing risk of water scarcity, yet contrasted results have been reported regarding mixing effects on tree drought exposure. ... -
Linking multiple-level tree traits with biomass accumulation in native tree species used for reforestation in Panama
(Springer Nature, 2007-12-12)To improve establishment yield and carbon accumulation during reforestation, analyses of species adaptations to local environments are needed. Here we measured, at the individual scale, links between biomass accumulation ... -
A general method for the classification of forest stands using species composition and vertical and horizontal structure
(Springer Nature, 2019)Key message. We present a novel approach to define pure- and mixed-forest typologies from the comparison of pairs of forest plots in terms of species identity, diameter, and height of their trees. Context. Forest typologies ... -
Predicting the spatial and temporal dynamics of species interactions in Fagus sylvatica and Pinus sylvestris forests across Europe
(Elsevier, 2017-09-28)The productivity and functioning of mixed-species forests often differs from that of monocultures. However, the magnitude and direction of these differences are difficult to predict because species interactions can be ... -
Coupling a water balance model with forest inventory data to predict drought stress: the role of forest structural changes vs. climate changes
(Elsevier, 2015-07-09)Mechanistic water balance models can be used to predict soil moisture dynamics and drought stress in individual forest stands. Predicting current and future levels of plant drought stress is important not only at the local ... -
