Invasive 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 ...
Amsterdam2024Chronic warming and dry soils limit carbon uptake and growth despite a longer growing season in beech and oak
Charlotte Grossiord, Yann Vitasse, 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 ...
Cary2023Warming may extend tree growing seasons and compensate for reduced carbon uptake during dry periods
Charlotte Grossiord, Christoph Bachofen, Yann Vitasse, Eugénie Isabelle Mas, 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 ...
Accounting for foliar gradients in Vc(max) and J(max) improves estimates of net CO2 exchange of forests
Vertical gradients in the canopy represent a major challenge for scaling from foliar photosynthesis to ecosystem-level CO2 fluxes. We tested whether accounting for independent gradients of carboxylation capacity (Vc(max)) and photosynthetic electron transp ...
ELSEVIER2022Foliar 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 ...
WILEY2021Effect of temperature and feeding on carbon budgets and O2 dynamics in Pocillopora damicornis
Niclas Heidelberg Lyndby, Michael Kühl
Studying carbon dynamics in the coral holobiont provides essential knowledge of nutritional strategies and is thus central to understanding coral ecophysiology. In this study, we assessed the carbon budget in Pocillopora damicornis (usingH13CO3) as a funct ...
2020Characterization of bacterial communities in Lake Geneva by comparing genetic and physiological methods
Over the last century, the level of atmospheric CO2 has increased to the highest concentrations on Earth within the past 800'000 years. Current predictions anticipate that the effects of greenhouse gases will lead to a rise in air temperature ranging betwe ...
2020Kleptoplastidic benthic foraminifera from aphotic habitats: insights into assimilation of inorganic C, N and S studied with sub-cellular resolution
Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin
The assimilation of inorganic compounds in foraminiferal metabolism compared to predation or organic matter assimilation is unknown. Here, we investigate possible inorganic-compound assimilation in Nonionellina labradorica, a common kleptoplastidic benthic ...
WILEY2019Kleptoplastidic benthic foraminifera from aphotic habitats: Assimilation (or not) of inorganic C, N, and S studied at sub-cellular resolution
Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin
The assimilation of inorganic compounds and their role in the foraminiferal metabolism compared to predation or organic matter assimilation is unknown. Here we investigate these processes with a study of the species Nonionellina labradorica (Dawson, 1860), ...
2018Correlated TEM-NanoSIMS investigation of foraminiferal metabolism
Charlotte Madeleine Nicole Lekieffre
Foraminifera are ubiquitous eukaryotic protists inhabiting all types of marine environments. The chemical and isotopic compositions of their carbonate tests are commonly used as proxies for paleo-environmental conditions. However, while foraminifera repres ...
