Invasive palms have more efficient and prolonged CO2 assimilation compared to native sub-Mediterranean vegetation

Charlotte Grossiord, Christoph Bachofen, Janisse Deluigi, Thibaut Michel Georges Juillard

In sub-Mediterranean ecosystems, shade-tolerant broadleaf evergreens, especially the invasive Trachycarpus fortunei, are spreading uncontrollably in the forest understorey, impeding the regeneration of the native deciduous woody vegetation. Most invasive s ...

Hotter droughts alter resource allocation to chemical defenses in pinon pine

Charlotte Grossiord

Heat and drought affect plant chemical defenses and thereby plant susceptibility to pests and pathogens. Monoterpenes are of particular importance for conifers as they play critical roles in defense against bark beetles. To date, work seeking to understand ...

Hydraulic architecture explains species moisture dependency but not mortality rates across a tropical rainfall gradient

Charlotte Grossiord

Intensified droughts are affecting tropical forests across the globe. However, the underlying mechanisms of tree drought response and mortality are poorly understood. Hydraulic traits and especially hydraulic safety margins (HSMs), that is, the extent to w ...

VPDrought – a novel approach to disentangle atmospheric and soil drought in a natural Scots pine forest

Charlotte Grossiord, Giovanni Bortolami

In recent years, an increasing number of studies have reported on forest declines and shifts in species composition in response to changing climatic conditions (Rigling et al. 2012). The intensification of droughts through rising evaporative demand (i.e., ...

Disentangling the Effects of Vapor Pressure Deficit and Soil Water Availability on Canopy Conductance in a Seasonal Tropical Forest During the 2015 El Niño Drought

Charlotte Grossiord

Water deficit in the atmosphere and soil are two key interactive factors that constrain transpiration and vegetation productivity. It is not clear which of these two factors is more important for the water and carbon flux response to drought stress in ecos ...

Tree functioning under different soil water availability and atmospheric water demand

Charlotte Grossiord, Giovanni Bortolami

As a consequence of ongoing climate change, trees are increasingly exposed to atmospheric and soil drought. The project “VPDrought - a novel approach to disentangle atmospheric and soil drought” investigates how trees respond to distinct and combined chang ...

Acclimation to High Vapor Pressure Deficit in Warmer Air Can Reduce Tree Vulnerability to Drought-Induced Mortality

Charlotte Grossiord, Laura Mekarni

Climate change imposes new constraints on tree survival, emphasising two key parameters: the vapour pressure deficit (VPD) and air temperature. Yet, no study has experimentally evaluated drought-induced tree mortality risk following acclimation to elevated ...

Tree diversity reduces variability in sapling survival under drought

Jingjing Liang, Charlotte Grossiord

Enhancing tree diversity may be important to fostering resilience to drought-related climate extremes. So far, little attention has been given to whether tree diversity can increase the survival of trees and reduce its variability in young forest plantatio ...

Interactions between beech and oak seedlings can modify the effects of hotter droughts and the onset of hydraulic failure

Charlotte Grossiord, Eugénie Isabelle Mas, Janisse Deluigi, Margaux Clara Lou Didion-Gency

center dot Mixing species with contrasting resource use strategies could reduce forest vulnerability to extreme events. Yet, how species diversity affects seedling hydraulic responses to heat and drought, including mortality risk, is largely unknown. Using ...

Reduced soil moisture drives leaf anatomical shifts more than chronically elevated temperatures in European temperate trees

Charlotte Grossiord, Janisse Deluigi, Thibaut Michel Georges Juillard

Chronic reductions in soil moisture combined with high air temperatures can modify tree carbon and water relations. However, little is known about how trees acclimate their foliar structure to the individual and combined effects of these two climate driver ...

In vivo X-ray microtomography locally affects stem radial growth with no immediate physiological impact

Charlotte Grossiord, Pascal Turberg, Laura Mekarni

Microcomputed tomography (mu CT) is a nondestructive X-ray imaging method used in plant physiology to visualize in situ plant tissues that enables assessments of embolized xylem vessels. Whereas evidence for X-ray-induced cellular damage has been reported, ...

Prolonged warming and drought reduce canopy‐level net carbon uptake in beech and oak saplings despite photosynthetic and respiratory acclimation

Alvaro Ruben Poretti, Charlotte Grossiord, Christoph Bachofen, Eugénie Isabelle Mas, Janisse Deluigi, Laura Mekarni, Margaux Clara Lou Didion-Gency

Tree net carbon (C) uptake may decrease under global warming, as higher temperatures constrain photosynthesis while simultaneously increasing respiration. Thermal acclimation might mitigate this negative effect, but its capacity to do so under concurrent s ...

Nature-based solution enhances resilience to flooding and catalyzes multi-benefits in coastal cities in the Global South

Jérôme Chenal, Paolo Perona, Charlotte Grossiord, Montana Marshall, Emmanuel Qays Dubois

Coastal cities are facing a rise in groundwater levels induced by sea level rise, further triggering saturation excess flooding where groundwater levels reach the topographic surface or reduce the storage capacity of the soil, thus stressing the existing i ...

Tree water uptake patterns across the globe

Charlotte Grossiord, Christoph Bachofen

Plant water uptake from the soil is a crucial element of the global hydrological cycle and essential for vegetation drought resilience. Yet, knowledge of how the distribution of water uptake depth (WUD) varies across species, climates, and seasons is scarc ...

Aridity and cold temperatures drive divergent adjustments of European beech xylem anatomy, hydraulics and leaf physiological traits

Charlotte Grossiord

Understanding plant trait coordination and variance across climatic gradients is critical for assessing forests' adaptive potential to climate change. We measured 11 hydraulic, anatomical and leaf-level physiological traits in European beech (Fagus sylvati ...

Mechanisms of woody-plant mortality under rising drought, CO2 and vapour pressure deficit

Charlotte Grossiord

Drought-associated woody-plant mortality has been increasing in most regions with multi-decadal records and is projected to increase in the future, impacting terrestrial climate forcing, biodiversity and resource availability. The mechanisms underlying suc ...

Soil warming alters tree water use and canopy stomatal conductance in a mixed subtropical forest

Charlotte Grossiord, Christoph Bachofen

As air temperature and vapor pressure deficit (VPD) increase continuously, forests are losing more water through evapotranspiration, with large consequences for local and global hydrological cycles. In regions with high vegetation cover, soil warming can b ...
