Abstract Forecasted increase drought frequency and severity may drive worldwide declines in forest productivity. Species‐level responses to a drier world are likely be influenced by their functional traits. Here, we analyse resilience using an extensive network of tree‐ring width data satellite imagery. We compiled proxies growth productivity ( TRW i, absolutely dated ring‐width indices; NDVI , Normalized Difference Vegetation Index) for 11 tree species 502 forests Spain corresponding...
Drought-triggered declines in forest productivity and associated die-off events have increased considerably due to climate warming the last decades. There is an increasing interest quantifying resilience capacity of forests against drought uncover how different stands tree species will resist recover after more frequent intense droughts. Trees form annual growth rings that represent accurate record responded past Here we use dendrochronology quantify radial subjected contrasting climatic...
Abstract Global climate change is expected to further raise the frequency and severity of extreme events, such as droughts. The effects droughts on trees are difficult disentangle given inherent complexity drought events (frequency, severity, duration, timing during growing season). Besides, might be modulated by trees’ phenotypic variability, which is, in turn, affected long‐term local selective pressures management legacies. Here we investigated magnitude temporal changes tree‐level...
Significance Forests dominate carbon fluxes in terrestrial ecosystems. We demonstrate how an intensified climatic influence on tree growth during the last 120 y has increased spatial synchrony annual ring-width patterns within contrasting (boreal and Mediterranean) Eurasian biomes broad scales. Current trends are related to regional changes climate factors controlling productivity, overriding local taxonomic imprints forest dynamics. Enhanced is becoming a widespread, although regionally...
Growth models can be used to assess forest vulnerability 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 particularly threatened. Here, we address these statements by analyzing projecting growth responses of three major species (silver fir, Abies alba; Scots pine, Pinus sylvestris; mountain uncinata) mountainous areas NE Spain. This region is subjected...
Abstract X‐ray microdensitometry on annually resolved tree‐ring samples has gained an exceptional position in last‐millennium paleoclimatology through the maximum latewood density (MXD) parameter, but also increasingly other parameters. For 50 years, based measurement techniques have been de facto standard. However, studies report offsets mean levels for MXD measurements derived from different laboratories, indicating challenges of accuracy and precision. Moreover, reflected visible...
Significance Climate extremes are major drivers of long-term forest growth trends, but we still lack appropriate knowledge to anticipate their effects. Here, apply a conceptual framework assess the vulnerability Circum-Mediterranean Abies refugia in response climate warming, droughts, and heat waves. Using tree-ring network process-based model, future Mediterranean forests. Models abrupt reductions for late 21st century when climatic conditions will be analogous most severe dry/heat spells...
Abstract The negative impacts of drought on forest growth and productivity last for several years generating legacies, although the factors that determine why such legacies vary across sites tree species remain unclear. We used an extensive network tree‐ring width (RWI, ring‐width index) records 16 from 567 forests, high‐resolution climate normalized difference vegetation index (NDVI) datasets Spain during common period 1982‒2008 to test hypothesis conditions features modulate legacy effects...
Abstract Aim We investigate the effects of environmental and geographical processes driving growth resilience recovery in response to drought Mediterranean Pinus pinaster forests. explicitly consider how intraspecific variability modulates drought. Location Western basin. Methods analysed tree rings from a large network 48 forests (836 trees) encompassing wide ecological climatic gradients, including six provenances. To characterize major constraints P. under extremely dry conditions, we...
Abstract Climate warming is expected to positively alter upward and poleward treelines which are controlled by low temperature a short growing season. Despite the importance of as bioassay climate change, global field assessment posterior forecasting tree growth at annual scales lacking. Using annually resolved tree‐ring data located across Eurasia Americas, we quantified modeled relationship between radial treeline during 20th century. We then tested whether this temperature–growth...
Tree phenology is sensitive to climate warming and changes in seasonal precipitation. Long xylogenesis records are scarce, thus limiting our ability analyse how radial growth responds variability. Alternatively, process-based models can be used simulate intra-annual dynamics better understand why bimodality varies along temperature precipitation gradients. We the Vaganov-Shashkin (VS) model main climatic drivers of eight trees shrubs conifers (four pines four junipers) across Spain. selected...
Mediterranean pine forests display high resilience after extreme climatic events such as severe droughts. However, recent dry spells causing growth decline and triggering forest dieback challenge the capacity of some to recover following major disturbances. To describe how resilient responses drought can be, we quantified dynamics in plantations two species (Scots pine, black pine) located south-eastern Spain showing drought-triggered dieback. Radial was characterized at inter- (tree-ring...
Rear-edge populations at the xeric distribution limit of tree species are particularly vulnerable to forest dieback triggered by drought. This is case silver fir (Abies alba) forests located in Southwestern Europe. While drought-induced patterns have been previously explored, information on role played nutritional impairment lacking despite its potential interactions with carbon-water balances. We performed a comparative analysis radial growth, intrinsic water-use efficiency (iWUE), oxygen...

The impacts drought decline pines have not been evaluated considering species different vulnerability and contrasting climates.
