TLALOC : un modèle spatio-temporel de la dynamique des communautés végétales en lien avec la dynamique érosive et sédimentaire de ravines marneuses

open access: yesSciences, Eaux & Territoires, 2009
Les ravines marneuses des Alpes du Sud subissent fréquemment des crues torrentielles. Ces dernières sont à l'origine de phénomènes érosifs ayant des conséquences néfastes en aval (augmentation du risque d'inondation et envasement des barrages hydro ...

Bridging the Gap From Peat to Ponds: Terrestrial and Aquatic Greenhouse Gas Emissions in an Evolving Permafrost‐Associated Subarctic Peatland

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract Rapid permafrost thaw in peatlands transforms the subarctic landscape into a mosaic of ponds and peat soil, varying in moisture, carbon and nutrients, and time since thaw. As subarctic permafrost degrades, ponds emerge and mature and can gradually infill with Sphagnum peat.

Electroreduction of CO2 From Flue Gas: Impurity Tolerance and Mechanistic Insights in Molecular Catalysis

open access: yesChemSusChem, Volume 19, Issue 6, 27 March 2026.
Impurity‐tolerance exhibited by Re molecular complex for CO2 conversion from flue gas containing 10% CO2, 10% O2, 100 ppm NO2 and 50 ppm SO2 in N2 matrix. This tolerance is based on electrochemical reduction of gas impurities on the electrode surface under CO2 electrolysis conditions.

Pairing Spruce Budworm Control and Minimal Understory Perturbations: Effects of Btk Spraying Frequency in Boreal Forests

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
Spruce budworm epidemic induces tree mortality and modifies understory communities. Could aerial spraying of Btk reduce perturbations in understory communities? Biannual Btk spraying could prevent both wood loss and understory degradation. ABSTRACT Since 1985, more than 10 million hectares of Canadian forests have been treated against spruce budworm ...
