FORESTS 10/01/21 Xylem Phenology and Growth Response of European Beech, Silver Fir and Scots Pine along an Elevational Gradient during the Extreme Drought Year 2018. Highlights: European beech (Fagus sylvatica L.) and silver fir (Abies alba Mill.) displayed parabolic elevational trends of the cessation of xylem cell differentiation phases.

FORESTS 10/01/21 Xylem Phenology and Growth Response of European Beech, Silver Fir and Scots Pine along an Elevational Gradient during the Extreme Drought Year 2018

Xylem phenology and growth rates of Scots pine (Pinus sylvestris L.) appeared to be less influenced by the 2018 drought, whereas beech reduced growth on the lowest elevation and fir seemed negatively affected in general. Background: The year 2018 was characterized by multiple drought periods and heat waves during the growing season.

SCIENCE DAILY 10/08/17 Climate change: Silver fir beats Norway spruce and European beech

The trees would have to adapt genetically to the rapidly changing climate to continue flourishing at their current growth location. Yet, they are unlikely to do so in such a short period of time -- a single tree generation already takes 100 years or longer. Therefore, the question on how well adapted the trees already are today to the future climate will be crucial for the forests' future. Unique comparison of Norway spruce, silver fir and European beech A WSL research team led by Caroline Heiri, investigated for the first time the climate change induced risk faced by the three most important tree species for the Swiss forestry sector and timber industry: Norway spruce, silver fir and European beech.

The results certainly astonished. The deciduous European beech is also exposed to climate risks, but less pronounced than Norway spruce. Rev. For. Fr.

LE BERRY 28/09/20 La forêt domaniale de Vierzon souffre de plus en plus des sécheresses et des fortes chaleurs : « Les hêtres meurent massivement »

Dans la forêt domaniale de Vierzon, « les hêtres meurent massivement », constate Alexis Hachette, responsable de l’unité territoriale de l’Office national des forêts (ONF) à Vierzon. Avec son équipe, il observe que c’est « l’espèce qui paye un lourd tribut depuis trois ans » face à la sécheresse, le manque d’eau et les fortes températures estivales. « C’est un arbre qui souffre de plus en plus à Vierzon », souligne Alexis Hachette. Et le phénomène est grandissant. « Un expert arbre conseil passe, chaque année, sur le sentier de la Salamandre (sentier aménagé et adapté qui accueille du public, labellisé Espace naturel sensible, NDLR).

Fin 2018, nous avions deux arbres à traiter. Au printemps 2020, après son passage, nous avons reçu le rapport qui indique qu’il y a, dorénavant, cinquante-sept arbres à traiter, c’est-à-dire abattre des arbres ou les élaguer car ils deviennent potentiellement dangereux. JOURNAL OF EVOLUTIONARY BIOLOGY 03/03/20 Climate‐associated genetic variation in Fagus sylvatica and potential responses to climate change in the French Alps. Local adaptation patterns have been found in many plants and animals, highlighting the genetic heterogeneity of species along their range of distribution.

JOURNAL OF EVOLUTIONARY BIOLOGY 03/03/20 Climate‐associated genetic variation in Fagus sylvatica and potential responses to climate change in the French Alps

In the next decades, global warming is predicted to induce a change in the selective pressures that drive this adaptive variation, forcing a reshuffling of the underlying adaptive allele distributions. For species with low dispersion capacity and long generation time such as trees, the rapidity of the change could impede the migration of beneficial alleles and lower their capacity to track the changing environment. Identifying the main selective pressures driving the adaptive genetic variation is thus necessary when investigating species capacity to respond to global warming.

In this study, we investigate the adaptive landscape of Fagus sylvatica along a gradient of populations in the French Alps. GLOBAL CHANGE BIOLOGY 04/07/17 Risk of genetic maladaptation due to climate change in three major European tree species. Aim To better understand and more realistically predict future species distribution ranges, it is critical to account for local adaptation and phenotypic plasticity in populations' responses to climate.

This is challenging because local adaptation and phenotypic plasticity are trait‐dependent and traits covary along climatic gradients, with differential consequences for fitness. Our aim is to quantify local adaptation and phenotypic plasticity of vertical and radial growth, leaf flushing and survival across the range of Fagus sylvatica and to estimate the contribution of each trait to explaining the species' occurrence.
