Abstract The dataset presented here was collected by the GenTree project (EU-Horizon 2020), which aims to improve use of forest genetic resources across Europe better understanding how trees adapt their local environment. This individual tree-core characteristics including ring-width series and whole-core wood density for seven ecologically economically important European tree species: silver birch ( Betula pendula ), beech Fagus sylvatica Norway spruce Picea abies black poplar Populus nigra...
Genetic association studies in forest trees would greatly benefit from information on the response of to environmental stressors over time, which can be provided by dendroecological analysis. Here, we jointly analysed and genetic data surviving silver fir explore basis their iconic stress episode 1970s 1980s that led large-scale dieback Central Europe has been attributed air pollution. Specifically, derived dendrophenotypic measures 190 Bavarian Forest characterize resistance, resilience...
In a climate change perspective, the resilience of Mediterranean forest ecosystems is closely linked to their ability cope with drought and rising temperatures. This can be influenced by genetic differences between within species or provenances. changing environment, management guidelines should weight risks associated both local and/or non-local provenances, promote effective conservation sustainable resilient resources. this study, we analysed growth responses silver fir (Abies alba) in...
Fragmentation can affect the demographic and genetic structure of populations near boundary their biogeographic range. Higher differentiation among coupled with lower level within-population variability is expected as a consequence reduced population size isolation. The effects these 2 factors have been rarely disentangled. Given high gene flow, anemophilous forest trees should be more affected, in terms loss diversity, by small rather than geographic isolation alone. We studied impact...
Abstract Aim Mediterranean refugial areas are generally underrepresented in large‐scale genetic surveys of forest trees. In the case silver fir ( Abies alba Mill.), this has led to divergent hypotheses about exact location glacial refugia and trajectory recolonization routes. Based on comprehensive sampling Apennine populations, we aimed reconcile discrepancies number for Apennines test alternative demographic scenarios developed from palaeobotanical data. Location Basin; surrounding areas....
Abstract Aim Climate is a major driver of large‐scale variability in biodiversity, as likely result more intense biotic interactions under warmer conditions. This idea fuelled decades research on plant‐herbivore interactions, but much less known about higher‐level trophic interactions. We addressed this gap by characterizing both bird diversity and avian predation along climatic gradient at the European scale. Location Europe. Taxon Insectivorous birds pedunculate oaks. Methods deployed...
Abstract Human activities have dramatically affected the status of river ecosystems, mainly by completely altering their natural dynamics. One main questions in this regard is: 'How do origin (natural or artificial) and hydrology (lentic lotic) a riverine wetland influence its heterogeneity functional diversity vegetation?' To answer question, data from 60 wetlands were collected along Oglio River (northern Italy), ~700 km 2 ecosystem that is typically over‐exploited plain. In order to...
The quantitative assessment of wood anatomical traits offers important insights into those factors that shape tree growth. While it is known conduit diameter, cell wall thickness, and density vary substantially between within species, the interconnection traits, tree-ring width, height age, as well environment effects on anatomy remain unclear. Here, we measure derived 65 in cross-sections five outermost rings (2008–2012) 30 Norway spruce (Picea abies (L.) H. Karst.) trees growing along an...
Abstract High genetic variation and extensive gene flow may help forest trees with adapting to ongoing climate change, yet the bases underlying their adaptive potential remain largely unknown. We investigated range‐wide patterns of potentially in 64 populations European beech ( Fagus sylvatica L.) using 270 SNPs from 139 candidate genes involved either phenology or stress responses. inferred neutral structure processes (drift flow) performed differentiation outlier analyses gene‐environment...
Background Local adaptation is a key driver of phenotypic and genetic divergence at loci responsible for adaptive traits variations in forest tree populations. Its experimental assessment requires rigorous sampling strategies such as those involving population pairs replicated across broad spatial scales. Methods A hierarchical Bayesian model selection (HBM) that explicitly considers both the replication environmental contrast structure among study sites introduced. power was assessed...
The Kunming-Montreal Global Biodiversity Framework recognised the urgency of taking action to conserve intraspecific genetic diversity (IGD) as an insurance against habitat degradation and environmental change. Recent work suggests that 90–99 % IGD should be conserved safeguard viability future generations. Here, we addressed such a conservation issue in three forest tree species Italy: silver fir (Abies alba Mill.), Heldreich's pine (Pinus heldreichii H. Christ), pedunculate oak (Quercus...
Most tree species underwent cycles of contraction and expansion during the Quaternary. These led to an ancient complex genetic structure that has since been affected by extensive gene flow strong local adaptation. The extent which hybridization played a role in this multi-layered is important be investigated. To study effect on joint population two dominant Eurasian boreal forest, Picea abies P. obovata, we used targeted resequencing obtained around 480 K nuclear SNPs 87 chloroplast 542...
Abstract An increase in biotic interactions towards lower latitudes is one of the most consistent patterns ecology. Higher temperatures and more stable climatic conditions at low are thought to enhance interactions, accelerating biological evolution leading stronger anti-herbivore defences plants. However, some studies report contradictory findings, highlighting need for further investigation into underlying mechanisms. We used a combination field observations feeding trials controlled...
The fine-scale assessment of both spatially and non-spatially distributed genetic variation is crucial to preserve forest resources through appropriate management. Cryptic within-population structure may be more common than previously thought in tree populations, which has strong implications for the potential forests adapt environmental change. present study was aimed at comparing European beech (Fagus sylvatica L.) plots experiencing different disturbance levels. Five plot pairs made up by...
In the European plains, up to eighty percent of riverine wetlands have been lost due alteration hydrological regime and catchment exploitation. This condition is expected be further negatively exacerbated by climate change. To better understand observed change in distribution patterns hydro-hygrophilous vegetation temperate Mediterranean floodplains, a survey was conducted within lower Oglio River reach Northern Italy. river mid-size, altered nutrient-rich left tributary Po River.

Abstract Aim Marginal tree populations, either those located at the edges of species' range or in suboptimal environments, are often a valuable genetic resource for biological conservation. However, there is lack knowledge about consequences population marginality, estimated across entire ranges. Our study addresses this gap by providing information several indicators and their variability marginal core populations identified using quantitative marginality indices. Location Southwestern...
