Climate model projections suggest widespread drying in the Mediterranean Basin and wetting Fennoscandia coming decades largely as a consequence of greenhouse gas forcing climate. To place these other "Old World" climate into historical perspective based on more complete estimates natural hydroclimatic variability, we have developed World Drought Atlas" (OWDA), set year-to-year maps tree-ring reconstructed summer wetness dryness over Europe during Common Era. The OWDA matches accounts severe...
Abstract Aim Climate change is expected to modify growth trends of forests around the world. However, this modification may vary in strength and intensity across a species' biogeographical range. Here, we study European populations silver fir ( Abies alba ) its southern distribution limits Spain, Italy Romania. We hypothesized that will differ range, with marked decline drought‐prone regions near southernmost limits. Location Europe (Spain, Italy, Romania). Methods collected tree‐ring data...
Under predicted climate change, native silver fir (Abies alba) and European beech (Fagus sylvatica) are the most likely replacement species for Norway spruce (Picea abies) monocultures planted across large parts of continental Europe. Our current understanding adaptation potential fir-beech mixed forests to change is limited because long-term responses two environmental changes have not yet been comprehensively quantified. We compiled analysed tree-ring width (TRW) series from 2855 dominant,...
Summary Growth rates of European silver fir ( Abies alba Mill.) rapidly increased in the last century. At same time, ring widths declined at species southern distribution limits Mediterranean. Such diverse growth trends and responses have largely been attributed to regional climate conditions, but this was prior considering species' post‐glacial phylogeny. A dendrochronological network composed 1961 tree‐ring width series TRW ) from 78 sites between 365 1400 m a.s.l. along Carpathian Arc...
This paper aims to develop the first differentiated (earlywood—EW, latewood—LW, and total ring width—RW) dendrochronological series for ash (Fraxinus excelsior L.) oak (Quercus robur trees from Republic of Moldova, analyze their climatic response spatio-temporal stability. For this, 18 26 were cored Dobrușa protected area, Eastern Europe, new EW, LW, RW chronologies developed covering last century. The obtained results showed that LW have a similar both species, while EW is capturing...
Abstract Numerical simulations indicate that extreme climate events (e.g., droughts, floods, heat waves) will increase in a warming world, putting enormous pressure on society and political decision-makers. To provide long-term perspective the variability of these events, here we use ~700 years tree-ring oxygen isotope chronology from Eastern Europe, combination with paleo-reanalysis data, to show summer drying over Europe observed last ~150 is best our knowledge unprecedented 700 years....
ABSTRACT With ongoing global warming, increasing water deficits promote physiological stress on forest ecosystems with negative impacts tree growth, vitality, and survival. How individual species will react to increased drought is therefore a key research question address for carbon accounting the development of climate change mitigation strategies. Recent tree‐ring studies have shown that trees at higher latitudes benefit from warmer temperatures, yet this likely highly species‐dependent...
The future performance of the widely abundant European beech (Fagus sylvatica L.) across its ecological amplitude is uncertain. Although considered drought-sensitive and thus negatively affected by drought events, scientific evidence indicating increasing vulnerability under climate change on a cross-regional scale remains elusive. While evaluating changes in sensitivity secondary growth offers promising avenue, studies from productive, closed-canopy forests suffer knowledge gaps, especially...
<Abstract>Earlier studies suggested that the Mesovoid Shallow Substratum (MSS), a subterranean network of voids immediately under soil and scree horizon, might play an important role in life cycle some troglobitic species. No ecological have been conducted to test whether this terrestrial shallow habitat only plays for few or preferential species, it is also faunal structure dynamics. We investigated spatial temporal patterns arthropod community MSS sub-alpine analysed correlations with...
Stomatal O3 flux accumulated over the growing season (or phytotoxic ozone dose above a y threshold of uptake, PODy) is nowadays considered as best biologically based metric to assess injury vegetation and establishing critical levels (CLs). So far, CLs have used biomass losses forest-health indicator in experimental research. Ozone-induced adult forests, however, are difficult assess. We stress need reconcile present dose-response functions estimate O3-induced losses. In fact, clear...
Abstract The mechanistic pathways connecting ocean-atmosphere variability and terrestrial productivity are well-established theoretically, but remain challenging to quantify empirically. Such quantification will greatly improve the assessment prediction of changes in carbon sequestration response dynamically induced climatic extremes. jet stream latitude (JSL) over North Atlantic-European domain provides a synthetic robust physical framework that integrates climate not accounted for by...
In the context of forecasted climate change scenarios, growth forest tree species at their distribution margin is crucial to adapt current management strategies. Analyses beech (Fagus sylvatica L.) have shown high plasticity, but easternmost populations been rarely studied. To describe response marginal population in far east sites its distribution, we first compiled new ring width chronologies. Then analyzed climate-growth relationships for three Republic Moldova. We observed a relatively...
In this study, we made use of a regional oak tree-ring network from six stands that cover the northern Moldavian Plateau (eastern Europe) to analyze how different tree ring parameters (i.e., early wood width, late and total width) Quercus sp. are influenced by occurrence extreme climatic events (e.g., long-lasting drought events). order explore influence hydroclimatic on have selected each most positive negative years growth addressed seasonal cycle in comparison with main parameters, then...
