ABSTRACT Aim To assess the spatial patterns of forest expansion (encroachment and densification) for mountain pine ( Pinus uncinata Ram.) during last 50 years at a whole range scale by study different topographic socio‐economic potential drivers in current context global change. Location The area includes distributional Catalan Pyrenees (north‐east Spain). This represents more than 80 municipalities, covering total 6018 km 2 . Methods Forest cover was obtained image reclassification 200...

Location More than 1000 linear kilometres sub‐alpine (north‐east S pain) Methods Using aerial photographs supervised classification, we reclassified images into a binary raster with ‘tree’ ‘non‐tree’ values, determined canopy cover We then change 2006 based changes forest cover. used distance from to theoretical potential –...
Abstract Aim Current interest in forecasting changes to species ranges has resulted a multitude of approaches distribution models ( SDMs ). However, most include only small subset the available information, and many ignore smaller‐scale processes such as growth, fecundity dispersal. Furthermore, different often produce divergent predictions with no simple method reconcile them. Here, we present flexible framework for integrating at multiple scales using hierarchical Bayesian methods....
Abstract Mountain forests face important threats from global change and spatio-temporal variation in tree height can help to monitor these effects. In this study, we used the Global Ecosystem Dynamics Investigation space-borne laser sensor examine relationship between maximum elevation, role of climate, main European mountain ranges. We found a piecewise elevation all ranges, supporting existence common breakpoint that marks beginning development limitations. Temperature precipitation were...
Mountain regions in Western Europe have gone through a massive rural–urban migration and the collapse of their traditional socioeconomic system. As result, forest has occupied many old pastures croplands. In protected areas – such as National Parks changes landscape can affect biodiversity other services, including values that motivated declaration. Any policy decision these requires quantifying extent impact land-cover consequences on structure functioning. this study we analyze patterns...
Abstract. Regional-level applications of dynamic vegetation models are challenging because they need to accommodate the variation in plant functional diversity, which requires moving away from broadly defined types. Different approaches have been adopted last years incorporate a trait-based perspective into modeling exercises. A common parametrization strategy involves using trait data represent between individuals while discarding taxonomic identity. However, this ignores phylogenetic...
Abstract Background Climate change is altering the fire regime and compromising post-fire recovery of vegetation worldwide. To understand factors influencing cover restoration, we calculated in 200,000 hectares western Mediterranean forest burned by 268 wildfires over a 27-year period (1988–2015). We used time series Tasseled Cap Transformation Brightness (TCTB) spectral transformation Landsat imagery to calculate recovery. Then, quantified importance main drivers (climate, severity,...
Abstract Forests are exposed to changing climatic conditions reflected by increasing drought and heat waves that increase the risk of wildfire ignition spread. Climatic variables such as rain wind well vegetation structure, land configuration forest management practices all factors determine burning potential wildfires. The assessment emissions released combustion is essential for determining greenhouse gases air pollutants. estimation wildfire-related depends on type fraction fuel (i.e.,...
Competition can intensify the struggle for resources among plants, affecting forest growth and dynamics. The intensity mode of competition – asymmetric vs. symmetric change along environmental gradients with time, impacting response plants to their environment, but this is seldom explicitly considered in management plans. In study, we aim (i) disentangle main tree-related factors that affect post-fire Pinus halepensis sapling growth; (ii) determine which characterizes species regeneration;...
Mixed and multi-layered forest ecosystems are sometimes more productive than monospecific single-layered ones. It has been suggested that trees of different species sizes occupy complementary positions in space, which would act as a mechanism to increase canopy light interception wood production. However, greater reduces the average amount variability transmitted radiation, offering fewer opportunities for all regenerate maintain heterogeneity long run. We investigated whether increasing...
Secondary succession (SS) is one of the main consequences abandonment agricultural and forestry practices in rural areas, causing -among other processes- woody encroachment on former pastures croplands. In this study we model monitor spatial evolution SS over semi-natural grassland communities mountain range Pyrenees Spain, during last 36 years (1984-2019). Independent variables for ‘annual-based’ ‘period-based’ modeling were drawn from a suite Surface Reflectance Landsat images, LandTrendr...
En los últimos años la gestión forestal está evolucionando frente a las consecuencias futuras y actuales del cambio climático. Para prepararse mejor se están ejecutando diferentes proyectos como, el LIFE ADAPT-ALEPPO tiene como objetivo desarrollo de herramientas adaptación bosques pino carrasco al Esta nota centra en adaptativa post-incendio para mejorar resiliencia incendiados hace 20 o 30 años. Los tratamientos consisten una reducción 95% densidad rodales situados Castilla-La Mancha,...
Regional mapping of Above Ground Biomass Density (AGBD) using Remote Sensing data has shown high accuracy but lacks replicability at a global scale. In contrast, models capture AGBD variability across biomes struggle with biome-specific accuracy. To address this gap, we develop and assess the performance Deep Learning model for 10-m resolution multi-source satellite (Sentinel-1, Sentinel-2, ALOS PALSAR-2, GEDI) four biomes: Mediterranean, taiga (boreal forests), tropical rainforests,...
Questions: Is light availability the main factor driving forest dynamics in Pyrenean sub-alpine forests? Do pines and firs differ growth, mortality morphological response to low availability? Can differences shade tolerance affect predictions of future biome changes forests absence thermal limitation? Location: Montane–sub-alpine ecotones Eastern Pyrenees (NE Spain). Methods: We evaluated plasticity, survival growth saplings Scots pine, mountain pine silver fir a mixed ecotone. For each...
