From roots to canopy: Unraveling the influence of species diversity on tree water relations under warmer and drier climates
The worsening of drought events with rising air temperature alters tree water relations causing severe hydraulic impairments and widespread forest mortality. Mixing tree species with contrasting hydraulic traits could reduce forest vulnerability to extreme ...
EPFL2024Soil 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 ...
Elsevier2024Investigation of microbial community dynamics in soil during variable hydrological forcing
Climate change is expected to alter the temporal distribution of precipitation events, leading to prolonged drought periods and an increased frequency of extreme precipitation events. Changes in precipitation pattern will directly affect soil moisture dyna ...
EPFL2024Invasive palms have more efficient and prolonged CO2 assimilation compared to native sub-Mediterranean vegetation
Charlotte Grossiord, Christoph Bachofen, Thibaut Michel Georges Juillard, Janisse Deluigi, Marco Conedera
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 ...
Amsterdam2024Fungal community composition predicts forest carbon storage at a continental scale
Forest soils harbor hyper-diverse microbial communities which fundamentally regulate carbon and nutrient cycling across the globe. Directly testing hypotheses on how microbiome diversity is linked to forest carbon storage has been difficult, due to a lack ...
Nature Portfolio2024Electron transfer reactions and their role in soil carbon cycling
Electron transfer reactions are central to the transformation of energy in the environment and play an important role in biogeochemical element cycling. In soils, one of the main drivers of carbon cycling is the activity of organisms that utilize the energ ...
2024Tree diversity reduces variability in sapling survival under drought
Charlotte Grossiord, Jingjing Liang, Xiaojuan Liu
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 ...
Wiley2024The cost of adaptability: resource availability constrains functional stability under pulsed disturbances
Global change exposes ecosystems to changes in the frequency, magnitude, and concomitancy of disturbances, which impact the composition and functioning of these systems. Here, we experimentally evaluate the effects of salinity disturbances and eutrophicati ...
Washington2024The microbial genomics of glacier-fed streams: adaptations to an extreme ecosystem
Glacier-fed streams are the cold, ultra-oligotrophic, and unstable streams that are fed by glacial meltwater. Despite these extreme conditions, they harbour a diverse and abundant microbial diversity that develops into biofilms, covering the boulders and s ...
EPFL2024Twenty years of irrigation acclimation is driven by denser canopies and not by plasticity in twig- and needle-level hydraulics in a Pinus sylvestris forest
Charlotte Grossiord, Christoph Bachofen, Eugénie Isabelle Mas, Hervé Cochard, Alice Jacqueline Frédérique Gauthey, Alex Tunas Corzon
Climate change is predicted to increase atmospheric vapor pressure deficit, exacerbating soil drought, and thus enhancing tree evaporative demand and mortality. Yet, few studies have addressed the longer-term drought acclimation strategy of trees, particul ...
