Winter post-droughts amplify extreme nitrate concentrations in German rivers
Hydrological extremes can affect nutrient export from catchments to streams, posing a threat to aquatic ecosystems. In this study, we investigated the effects of hydrological drought on nitrate concentrations in the streamflow of 182 German catchments from ...
Bristol2024Twenty 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 ...
Oxford2024From 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 ...
EPFL2024Interactions between beech and oak seedlings can modify the effects of hotter droughts and the onset of hydraulic failure
Charlotte Grossiord, Eugénie Isabelle Mas, Hervé Cochard, Margaux Clara Lou Didion-Gency, Janisse Deluigi, Fernando Valladares
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 ...
Hoboken2023The effects of previous summer drought and fertilization on winter non-structural carbon reserves and spring leaf development of downy oak saplings
Xiaoyu Wang, Yue Yang, Peng He
It is still unknown whether the previous summer season drought and fertilization will affect the winter non-structural carbohydrate (NSC) reserves, spring leaf development, and mortality of trees in the next year. We, therefore, conducted an experiment wit ...
FRONTIERS MEDIA SA2022Canopy dieback and recovery in Australian native forests following extreme drought
Alice Jacqueline Frédérique Gauthey
In 2019, south-eastern Australia experienced its driest and hottest year on record, resulting in massive canopy dieback events in eucalypt dominated forests. A subsequent period of high precipitation in 2020 provided a rare opportunity to quantify the impa ...
NATURE PORTFOLIO2022Photosynthetic acclimation and sensitivity to short- and long-term environmental changes in a drought-prone forest
Future climate will be characterized by an increase in frequency and duration of drought and warming that exacerbates atmospheric evaporative demand. How trees acclimate to long-term soil moisture changes and whether these long-term changes alter trees' se ...
OXFORD UNIV PRESS2022Root carbon and nutrient homeostasis determines downy oak sapling survival and recovery from drought
The role of carbon (C) and nutrient uptake, allocation, storage and especially their interactions in survival and recovery of trees under increased frequencies and intensities of drought events is not well understood. A full factorial experiment with four ...
2021Phenotypic plasticity versus ecotypic differentiation under recurrent summer drought in two drought-tolerant pine species
Despite worldwide reports of high tree mortality, growing evidence indicates that many tree species are well adapted to survive repeated dry spells. The drought resilience of trees is related to their phenotypic plasticity and ecotypic differentiation. Whe ...
WILEY2021Drought alters the biogeochemistry of boreal stream networks
Drought is a global phenomenon, with widespread implications for freshwater ecosystems. While droughts receive much attention at lower latitudes, their effects on northern river networks remain unstudied. We combine a reach-scale manipulation experiment, o ...
