Managing forests under climate change requires adaptation. The adaptive capacity of forest tree populations is huge but not limitless. Integrating evolutionary considerations into forestry practice will enhance the managed to respond climate-driven changes. Focusing on natural regeneration systems, we propose a general framework that can be used in various and complex local situations by managers, combination with their own expertise, integrate decision making for emergence an...
Abstract Interindividual variation in fecundities has major consequences on population evolutionary potential, through genetic drift and selection. Using two spatially explicit mating models that analyse the genotypes of seeds seedlings, we investigated male female within among three European beech ( Fagus sylvatica ) stands situated along an altitudinal gradient. Female individual fecundity distributions were both skewed this monoecious species, found a higher variance as compared to...
Summary The seed dispersal kernel is a major determinant of spatial population dynamics and distribution genetic diversity. Among the main methods to estimate it, inverse modelling ( IM ) gene shadow model GSM rely on counts in traps, whereas competing source CSM spatially explicit mating models SEMM s) compositions pools. Moreover, , exploit information from molecular markers, only exploits ignoring origins. These were also applied established seedlings. In presence post‐dispersal...
Evolutionary processes are expected to be crucial for the adaptation of natural populations environmental changes. In particular, capacity rear edge evolve in response species limiting conditions remains a major issue that requires address their evolutionary potential. situ quantitative genetic studies based on molecular markers offer possibility estimate potentials manipulating neither environment nor individuals which phenotypes measured. The goal this study was heritability and...
A central issue in plant evolutionary ecology is to understand how several coordinated suites of traits (i.e. syndrome) may be jointly selected within a single species. This study aims describe patterns variation and co‐variation functional water‐stressed tree population test their relationships with performance traits. Within Mediterranean Fagus sylvatica experiencing recurrent summer droughts, we investigated the phenotypic leaf unfolding phenology, area (LA), mass per (LMA), water content...
We carried out a population genetic study of 14 populations (692 plants characterised at 23 microsatellite loci) the plant species Antirrhinum majus L. (Plantaginaceae) across its geographic range. Our results showed that A. are genetically differentiated and diverse. also found small but statistically significant differentiation between subspecies pseudomajus striatum. Genetic diversity was higher in pseudomajus. Geographic distance both latitudinal longitudinal coordinates had no impact on...
Background: Plant phenological traits such as the timing of budburst or flowering can evolve on ecological timescales through response to fecundity and viability selection. However, interference with sexual selection may arise from assortative mating. This study aims investigate how these three components spring phenology combine in European beech populations contrasting environments (high versus low altitude). Methods: we monitored (TBB) 339 adult trees estimated their using spatially...

L’adaptation est un enjeu majeur de la gestion forestière dans le contexte du changement climatique La diversité génétique qui caractérise les arbres forestiers leur confère potentiel adaptatif très important mais pas illimité Prendre en compte mécanismes l’évolution pratiques adaptative renforcera capacité des forêts gérées à répondre aux changements et aléas induits par climat. En mettant l’accent sur cas régénération naturelle, nous proposons cadre conceptuel général permettant d’intégrer...
