Interactions 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 ...
Hoboken2023Phloem water isotopically different to xylem water: Potential causes and implications for ecohydrological tracing
Andrea Rinaldo, Paolo Benettin
The stable isotopes of hydrogen and oxygen in xylem water are often used to investigate tree water sources. But this traditional approach does not acknowledge the contribution of water stored in the phloem to transpiration and how this may affect xylem wat ...
WILEY2022One hundred years of Company Town: the case of Dalmine, Italy.
The appearance of new forms of inhabiting the space has emerged to meet citizens' demands and new business paradigms. The contemporary city embraces a postmodern concept. The outcome is a new biopolitical project that affects citizens' living conditions th ...
2022Increasing 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 ...
Wiley2022Phenotypic 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 ...
WILEY2021On the use of leaf water to determine plant water source: A proof of concept
Source water apportionment studies using the dual isotopes of oxygen and hydrogen have revolutionized our understanding of ecohydrology. But despite these developments-mostly over the past decade-many technical problems still exist in terms of linking xyle ...
WILEY2021Foliar respiration is related to photosynthetic, growth and carbohydrate response to experimental drought and elevated temperature
Short-term plant respiration (R) increases exponentially with rising temperature, but drought could reduce respiration by reducing growth and metabolism. Acclimation may alter these responses. We examined if species with different drought responses would d ...
WILEY2021Alfalfa leaf curl virus is efficiently acquired by its aphid vector Aphis craccivora but inefficiently transmitted
Faustine Ambroisine Charline Ryckebusch
Alfalfa leaf curl virus (ALCV) is the first geminivirus for which aphid transmission was reported. Transmission by Aphis craccivora was determined previously to be highly specific and circulative. Using various complementary techniques, the transmission jo ...
MICROBIOLOGY SOC2021Persistent decay of fresh xylem hydraulic conductivity varies with pressure gradient and marks plant responses to injury
Defining plant hydraulic traits is central to the quantification of ecohydrological processes ranging from land-atmosphere interactions, to tree mortality and water-carbon budgets. A key plant trait is the xylem specific hydraulic conductivity (Kx), that d ...
2020Tree growth, transpiration, and water-use efficiency between shoreline and upland red maple (Acer rubrum) trees in a coastal forest
Coastal shoreline forests are vulnerable to seawater exposure, the impacts of which will increase due to sea-level rise, but the long-term adaptation strategies and vulnerability of coastal forests are not well understood. We used whole-tree transpiration, ...
