Abstract: Growth models can be used to assess forest vulnerability to climate warming. If global warming amplifies water deficit in drought-prone areas, tree populations located at the driest and southernmost distribution limits (rear-edges) should be particularly threatened. Here, we address these statements by analyzing and projecting growth responses to climate of three major tree species (silver fir, Abies alba; Scots pine, Pinus sylvestris; and mountain pine, Pinus uncinata) in mountainous areas of NE Spain.

“…If, as argued by some authors, i) forests in the Mediterranean zone are especially vulnerable to these changes (EEA, 2008;Sánchez-Salguero et al, 2017); ii) the most sensitive functional group to this increase in aridity is precisely the sclerophyll group (Valladares et al, 2004), and iii) the holm oak is particularly sensitive to climate change due to its debatable ecophysiological tolerance and low water-use efficiency during episodes of extreme drought (Joffre et al, 2001;Martínez-Vilalta et al, 2002, Reichstein et al, 2002; then the findings of this study suggest that some holm oak stools may already be showing serious problems in this regard. Applying the process model GOTILWA, the following changes were predicted in a holm oak coppice under a scenario of increasing both temperature and atmospheric CO 2 and reducing water availability (Gracia et al, 1999c): increase in the proportion of gross primary production invested in maintenance respiration; increase in leaf shedding and decrease in mean leaf life and as a result of both of these factors, an increase in leaf production, in spite of which, the increase in leaf maintenance costs causes a decrease in LAI; decrease in wood production; tree mortality.…”

“…( Sánchez-Salguero et al, 2017). In this sense, growth in rear edges is often constrained by low precipitation levels and high evapotranspiration rates enhancing drought stress as shown by previous studies on silver fir, Scots pine, and beech (Jump et al, 2006;Piovesan et al, 2008;Camarero et al, 2011Camarero et al, , 2015b.…”

“…Furthermore, forest growth resilience seems to rely on the species considered, indicating species-specific responses to drought stress (Anderegg et al, 2015Gea-Izquierdo et al, 2017Peltier et al, 2016;Pretzsch et al, 2013;S anchez-Salguero, Camarero, Guti errez et al, 2017;Yin & Bauerle, 2017). Evergreen gymnosperms dominating the semi-arid and drought-prone areas displayed lower resistance but faster recovery than evergreen gymnosperms and deciduous angiosperms dominating the temperate and wet regions, suggesting different adaptations and physiological mechanisms to cope with drought ( Figure 3).…”

“…Remote sensing information from the red and near-infrared electromagnetic spectrum is used to calculate the Normalized Difference Vegetation Index (NDVI; Tucker, 1979), which has been widely used to determine drought impacts on forest activity and biomass in several regions worldwide (e.g. Gazol, Ribas, Guti errez, & Camarero, 2017;Lloret, Keeling, & Sala, 2011;Vitali, B€ untgen, & Bauhus, 2017), and only few studies have evaluated forest response to drought across broad environmental gradients, including several biomes, biogeographical regions, and tree species (but see Girardin et al, 2016;S anchez-Salguero, Camarero, Carrer et al, 2017;S anchez-Salguero, Camarero, Guti errez et al, 2017). Although linking tree-ring width and NDVI series may be limited by their different spatial and temporal scales, previous studies suggest a positive relationship between inter-annual NDVI variability and annual radial growth (Coulthard, Touchan, Anchukaitis, Meko, & Sivrikaya, 2017), despite discrepancies between different regions and forest types (Vicente-Serrano et al, 2016).…”
