Seed sourcing strategies are the basis for identifying genetic material meeting the requirements of future climatic conditions and social demands. Specifically, local seed sourcing has been extensively promoted, based on the expected adaptation of the populations to local conditions, but there are some limitations for the application. We analyzed S...
1. Riparian vegetation supports high biodiversity providing many services and is, therefore, an important landscape element. Riparian ecosystems are subject to numerous pressures leading to population decline and genetic erosion of riparian plants. This may have cascading effects at various ecosystem levels, including decreasing ecosystem services,...
Marginal and peripheral populations are important for biodiversity conservation. Their original situation in a species’ geographic and ecological space often confers them genetic diversity and traits of high adaptive value. Yet theoretical hypotheses related to marginality are difficult to test because of confounding factors that influence marginal...

Understanding species-specific responses to climate change allows a better assessment
of the possible impact of global warming on forest growth. We studied the responses of the shrub species Corylus avellana L., Corylus maxima Mill. and intermediate forms, together stated as the Corylus taxa, and Cornus sanguinea L. upon periodically elevated tempe...
Future predictions of forest ecosystem responses are a challenge, as global temperatures will further rise in the coming decades at an unprecedented rate. The effect of elevated temperature on growth performance and phenology of three Prunus spinosa L. provenances (originating from Belgium, Spain, and Sweden) in a common garden environment was inve...
Background:
Progress in the field of evolutionary forest ecology has been hampered by the huge challenge of phenotyping trees across their ranges in their natural environments, and the limitation in high-resolution environmental information.
Findings:
The GenTree Platform contains phenotypic and environmental data from 4,959 trees from 12 ecolog...
Premise:
Persistence of tree populations in the face of global change relies on their capacity to respond to biotic and abiotic stressors through plastic or adaptive changes. Genetic adaptation will depend on the additive genetic variation within populations and the heritability of traits related to stress tolerance. Because traits can be genetica...
Research Highlights: We experimentally tested different seed sourcing strategies (local, predictive, climate-predictive, climate-adjusted, composite and admixture) under a climate change high emissions scenario using a Scots pine multi-site provenance test. Background and Objectives: There is an urgent need to conserve genetic resources and to supp...
Rationale: Understanding the dynamics of selection is key to predict the response of tree species to new environmental conditions in the current context of climate change. However, selection patterns acting on early recruitment stages and its climatic drivers remain largely unknown in most tree species, despite being a critical period of their life...
Pinsapo fir (Abies pinsapo Boiss.) is an endangered Mediterranean conifer that has raised strong conservation interest as a paradigmatic example of species characterized by small and fragmented populations. We studied an old reforestation stand composed of A. pinsapo, Pinus nigra and Pinus sylvestris established in the 1910s in central-eastern Spai...
Given that the ecological niche of tree species is typically narrower for earlier life stages, intraspecific genetic variation at early fitness traits may greatly influence the adaptive response of tree populations to changing environmental conditions. In this study, we evaluated genetic variation in early fitness traits among 12 populations of Bet...

The dataset presented here was collected by the GenTree project (EU-Horizon 2020), which aims to improve the use of forest genetic resources across Europe by better understanding how trees adapt to their local environment. This dataset of individual tree-core characteristics including ring-width series and whole-core wood density was collected for...
Visual description (pictures) of three established stages of the primary growth in Pinus halepensis for standarization
During their long lifespan, pines must cope with simultaneous abiotic and biotic stresses such as drought and herbivory. Mediterranean pines are isohydric species that rapidly close their stomata in response to drought reducing carbon fixation. In such situations, the synthesis of chemical defences could be impaired. Here, we tested the hypothesis...
Water and carbon fluxes in forests are largely related to leaf gas exchange physiology varying across spatiotemporal scales and modulated by plant responses to environmental cues. We quantified the relevance of genetic and phenotypic variation of intrinsic water-use efficiency (WUEi, ratio of net photosynthesis to stomatal conductance of water) in...

Site index curves were created for natural Aleppo pine (Pinus halepensis Mill.) stands in the Ebro Valley (northeastern Spain). Data were obtained from 54 felled dominant trees. The Generalized Algebraic Difference Approach (GADA) was used to fit 11 equations with a longitudinal data structure that included all possible growth intervals. Three stat...
Agriculture and forestry activities are one of the many sources of greenhouse gas (GHG) emissions, but they are also sources of low-cost opportunities to mitigate these emissions compared to other economic sectors. This paper provides a first estimate of the potential for mitigation in the whole Spanish agriculture. A set of mitigation measures are...
•Premise of the study Serotiny, the maintenance of ripe seeds in closed fruits or cones until fire causes dehiscence, is a key adaptive trait of plants in fire-prone ecosystems, but knowledge of phenotypic plasticity for cone retention in woody plants is extremely scarce. Based both in literature and field observations, we hypothesized that increas...
Forest trees in Mediterranean continental areas undergo both summer and winter stress. Recent large-scale studies of regeneration patterns of pine and oak species have reported the expansion of Quercus ilex to the detriment of pine species. To asses this trend from a physiological point of view, we compared the effect of summer and winter stress on...

Background:
A central question for understanding the evolutionary responses of plant species to rapidly changing environments is the assessment of their potential for short-term (in one or a few generations) genetic change. In our study, we consider the case of Pinus pinaster Aiton (maritime pine), a widespread Mediterranean tree, and (i) test, un...
Despite being an abundant species as a whole, some subspecies and populations of the European black pine (Pinus nigra Arnold) are particularly threatened due to climate change and alterations of fire regimes across the Mediterranean basin. This is the case of westernmost populations of P. nigra salzmannii in the Spanish Central Range (mostly in Sie...
Semi-arid Mediterranean regions are highly susceptible to desertification processes which can reduce the benefits that people obtain from healthy ecosystems and thus threaten human wellbeing. The European Union Biodiversity Strategy to 2020 recognizes the need to incorporate ecosystem services into land-use management, conservation, and restoration...
Dynamic conservation of forest genetic resources (FGR) means maintaining the genetic diversity of trees within an evolutionary process and allowing generation turnover in the forest. We assessed the network of forests areas managed for the dynamic conservation of FGR (conservation units) across Europe (33 countries). On the basis of information ava...
We studied the intraspecific variability of maritime pine in a set of morphological and physiological traits: soil-to-leaf hydraulic conductance, intrinsic water-use efficiency (WUE, estimated by carbon isotope composition, δ(13)C), root morphology, xylem anatomy, growth and carbon allocation patterns. The data were collected from Pinus pinaster Ai...
We analysed proline, abscisic acid, (ABA), jasmonic acid (JA), indole acetic acid (IAA) and salicylic acid (SA) accumulation
after summer drought at two Pinus pinaster provenance-progeny trial sites. The aim of the study was to evaluate P. pinaster phenotypic plasticity and intraspecific variation in the endogenous concentrations of these metabolit...
As part of a program to select maritime pine (Pinus pinaster Ait.) genotypes for resistance to low winter temperatures, we examined variation in photosystem II activity by chlorophyll fluorescence. Populations and families within populations from contrasting climates were tested during two consecutive winters through two progeny trials, one located...
The objectives of the study were to assess the phenotypic variation in the vulnerability to water stress-induced cavitation
(estimated by P50, or the xylem water potential which causes a 50% loss of conductivity) and the trade-offs between P50 and related hydraulic traits, i.e., stem specific conductivity (K
s), slope of the vulnerability curve (sl...
• Carbon isotope composition (δ13C) is a complex trait involved in acclimation, adaptive processes and related to water use efficiency (WUE) and/or productivity.
• To estimate the genetic variation in δ13C and growth (h), their relationship, and the genotype by environment interaction effect in both variables, we analyzed three Pinus pinaster popul...
Life histories in Mediterranean pines are well known to be closely related to different fire and disturbance regimes. Variation in these factors is also reflected in reproductive strategies at the specific and intraspecific level. Specifically, the onset of reproduction is a crucial stage for any organism because it has profound implications on fit...

Black poplar (Populus nigra L.) is a keystone species for riparian ecosystems in Europe. We analysed the structure of genetic diversity of 17 populations from 11 river valleys that are part of seven catchment systems (Danube, Ebro, Elbe, Po, Rhine, Rhone, and Usk) in Europe, in relation to geography and river management. In total, 1069 trees were g...
El genero Populus constituye un material excelente para cualquier tipo de estudio debido a su rapidez de crecimiento y a su gran facilidad de propagación vegetativa que permite la producción de una gran cantidad de material clonal para la experimentación. Esto ha sido confirmado mediante numerosos estudios ecofisiológicos cuyo objetivo ha sido la d...
Scots pine (Pinus sylvestris L.) has the widest distribution of pine species and the populations are locally adapted to very different environmental conditions. Adaptive traits such as those related to growth are optimal for understanding adaptation of populations to local conditions in widely distributed forest species. A study of the timing of Gr...

Eleven laboratories have collaborated to study chloroplast DNA (cpDNA) variation in black poplar (Populus nigra L.) across Europe in order to improve our understanding of the location of glacial refugia and the subsequent postglacial routes of recolonisation. A common analysis based on the restricted fragments produced by five primer pairs was used...
Populus nigra L. is a pioneer tree species of riparian ecosystems that is threatened with extinction because of the loss of its natural habitat. To evaluate the existing genetic diversity of P. nigra within ex-situ collections, we analyzed 675 P. nigra L. accessions from nine European gene banks with three amplified fragment length polymorphism (AF...
Plants obtained from seed of 16 Spanish and 6 German provenances of Scots pine (Pinus sylvestris L.) were installed at five trial sites distributed throughout the natural range of the species in Spain. Five years after planting (7 years of age) the experimental material was measured for total height, diameter, number of twigs at the fourth year who...
The pattern of geographic variation and the relationship among genetic variation in quantitative and molecular traits have been investigated in 15 populations of Aleppo pine covering the range of its distribution in Spain. The FST was estimated by means of 5 polymorphic isozyme loci, and, in a subset of 6 populations, by 24 RAPDs and 9 Cp-microsate...
Se presentan dos aplicaciones de los modelos diagnosis e idoneidad (Allué, 1990, 1997) al estudio dos problemas existentes en la mejora genética forestal: la relación entre variación genética y clima a recomendación de uso del material forestal de reproducción, ambos aplicados a Pinus sylvestris en España. En un ensayo de procedencias situado en Ar...
Nine half-sib families of maritime pine (Pinus pinaster Ait.) of known adult performance were grown in continuous light at either 25 degrees C or 25/20 degrees C for 18 weeks. They were then exposed to a dormancy induction period followed by a dormancy release period and then grown for a further 9 weeks in a 16-h photoperiod at a day/night temperat...
Resumen El cambio global afecta a todos los ecosistemas terrestres, de entre los que destaca el papel de los bosques, que puede comportarse como fuente de emisión de CO 2 o como sumidero. La gestión forestal se revela como una herramienta de gran importancia en el control del problema, y para ello es necesario contabilizar y monitorizar la evolució...
