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 ...

Warming 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 ...

Foliar respiration is related to photosynthetic, growth and carbohydrate response to experimental drought and elevated temperature

Charlotte Grossiord

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 ...

Kleptoplastidic 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 ...

Correlated 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 ...

Quantitative Mass Spectrometry Reveals Plasticity of Metabolic Networks in Mycobacterium smegmatis

John McKinney, Tarun Chopra, Romain Hamelin, Florence Armand, Diego Chiappe, Marc Moniatte

Mycobacterium tuberculosis has a remarkable ability to persist within the human host as a clinically inapparent or chronically active infection. Fatty acids are thought to be an important carbon source used by the bacteria during long term infection. Catab ...

Endosomes: Guardians Against [Ru(Phen)3]2+ Photo-action In Endothelial Cells During In Vivo pO2 Detection?

Georges Wagnières, Veronika Huntosova

Phototoxicity is a side-effect of in vitro and in vivo oxygen partial pressure (pO(2)) detection by luminescence lifetime measurement methods. Dichlorotris(1,10-phenanthroline)-ruthenium(II) hydrate (Ru(Phen)(3)) is a water soluble pO(2) probe associ ...

The Response of the Mediterranean Gorgonian Eunicella singularis to Thermal Stress Is Independent of Its Nutritional Regime

Alexandre Buttler, Leïla Ezzat

Over the last few decades, sessile benthic organisms from the Mediterranean Sea have suffered from the global warming of the world's oceans, and several mass mortality events were observed during warm summers. It has been hypothesized that mortality could ...
