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

Yann Vitasse, Charlotte Grossiord, 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 ...

Warming may extend tree growing seasons and compensate for reduced carbon uptake during dry periods

Yann Vitasse, Charlotte Grossiord, Eugénie Isabelle Mas, Christoph Bachofen, Margaux Clara Lou Didion-Gency

Warming and drought alter plant phenology, photosynthesis and growth with important consequences for the global carbon cycle and the earth’s climate. Yet, few studies have attempted to tease apart their effects on tree phenology, particularly leaf senes ...

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

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

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 ...

Frost hardening and dehardening potential in temperate trees from winter to budburst

Amarante Vitra, Yann Vitasse

We investigated how deciduous trees can adjust their freezing resistance in response totemperature during the progress of the ecodormancy phase, from midwinter to bud burst. We regularly sampled twigs of four different temperate deciduous tree species from ...
