Chronic warming and dry soils limit carbon uptake and growth despite a longer growing season in beech and oak

Charlotte Grossiord, Yann Vitasse, Margaux Clara Lou Didion-Gency

Progressively warmer and drier climatic conditions impact tree phenology and carbon cycling with large consequences for forest carbon balance. However, it remains unclear how individual impacts of warming and drier soils differ from their combined effects ...

Increasing temperature and vapor pressure deficit lead to hydraulic damages in the absence of soil drought

Pascal Turberg, Charlotte Grossiord, Eugénie Isabelle Mas, Laura Mekarni, Philipp Schuler, Leonie Corine Schönbeck

Temperature (T) and vapor pressure deficit (VPD) are important drivers of plant hydraulic conductivity, growth, mortality, and ecosystem productivity, independently of soil water availability. Our goal was to disentangle the effects of T and VPD on plant h ...

Genetic signatures of divergent selection in European beech (Fagus sylvatica L.) are associated with the variation in temperature and precipitation across its distribution range

Elia Vajana

High genetic variation and extensive gene flow may help forest trees with adapting to ongoing climate change, yet the genetic bases underlying their adaptive potential remain largely unknown. We investigated range-wide patterns of potentially adaptive gene ...

Contrasting Leaf Trait Responses of Conifer and Broadleaved Seedlings to Altered Resource Availability Are Linked to Resource Strategies

Christoph Bachofen, Yan Li Zhang

(1) Understanding tree seedling responses to water, nutrient, and light availability is crucial to precisely predict potential shifts in composition and structure of forest communities under future climatic conditions. (2) We exposed seedlings of widesprea ...

Ecological response of tree saplings to simulated climate change along an elevational gradient (CLIMARBRE)

María Paula Sanginés De Cárcer

Switzerland will face higher temperature increases than the global average, which will have strong impacts on the mountain ecosystems. How tree species will respond to future climate change scenarios, and what mechanisms will they adopt, remains as a gap o ...

Asymmetric effects of cooler and warmer winters on beech phenology last beyond spring

Alexandre Buttler, Rodolphe Schlaepfer, Constant Signarbieux, María Paula Sanginés De Cárcer, Yann Vitasse, Ester Toledano Díaz

In temperate trees, the timings of plant growth onset and cessation affect biogeochemical cycles, water, and energy balance. Currently, phenological studies largely focus on specific phenophases and on their responses to warming. How differently spring phe ...

Responses of antinomic foliar traits to experimental climate forcing in beech and spruce saplings

Alexandre Buttler, Rodolphe Schlaepfer, Constant Signarbieux, María Paula Sanginés De Cárcer

Global warming is predicted to have a strong impact on mountain ecosystems. Subalpine sylvopastoral systems are very sensitive to climate change, which puts their future sustainability at stake. These ecosystems are mostly dominated by spruce and beech, an ...

Climate or migration: what limited European beech post-glacial colonization?

Basil Andrew Stansfield Davis

AimDespite the recent improvements made in species distribution models (SDMs), assessing species' ability to migrate fast enough to track their climate optimum remains a challenge. This study achieves this goal and demonstrates the reliability of a process ...

The influence of competition from herbaceous vegetation and shade on simulated browsing tolerance of coniferous and deciduous saplings

Alexandre Buttler, Charlotte Vandenberghe, François Frelechoux

The ability of saplings to tolerate browsing (i.e. the ability to persist with reduced biomass and to compensate for biomass loss) is influenced by the level of stress and their growth strategies. Ultimately, insight into species-specific responses of sapl ...

Short-term effects of cattle browsing on tree sapling growth in mountain wooded pastures

Alexandre Buttler, Charlotte Vandenberghe, François Frelechoux

Browsing by livestock has been identified as an important factor preventing tree regeneration in wooded pastures. Two field experiments were performed to investigate the effects of cattle browsing on tree sapling growth in a mountainwooded pasture. Two siz ...
