Cache‐Cache: Dans les souffles du Grand Fleuve…

open access: yesAnthropology of Consciousness, Volume 37, Issue 2, Fall 2026.
ABSTRACT Between ventriloquism and divination, devotion and consecration, an old and sublime marine game unfolds each day, with living breaths shared in the waters of the great river. In Tadoussac, on the north shore of the St. Lawrence Estuary, at the mouth of the Saguenay, the rumor of whales has long resonated.

Epilithic biomass in a large gravel-bed river (the Garonne, France): a manifestation of eutrophication? [PDF]

open access: yes, 2002
In order to evaluate the impact of outputs of the city of Toulouse (740 000 inhabitants) on the epilithic communities colonizing pebble banks in the river Garonne, a large gravel-bed river (eighth order), dry mass (DM), ash-free dry mass (AFDM) and ...

Can molecular oscillation technology be used as an alternative to acid injection to prevent the clogging of emitters in drip irrigation systems?

open access: yesIrrigation and Drainage, Volume 74, Issue 2, Page 586-599, April 2025.
Abstract In this study, molecular oscillation technology (Merus ring), developed to prevent calcification, biofilm formation and corrosion in piping in industrial water treatment systems, was compared as an alternative to acid injection to prevent the clogging of emitters by chemicals, and fresh and saline water were compared on the basis of system ...

Opinion and report of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) relating to an analysis of the health risks associated with exposure to caterpillars with stinging hairs and the development of management recommendations

open access: yesFood Risk Assess Europe, Volume 3, Issue 2, April 2025.
Abstract Several species of Lepidoptera with caterpillars bearing urticating hairs are increasing their range in metropolitan France from year to year, such as the pine processionary (Thaumetopoea pityocampa Denis et Schiffermüller 1775) whose presence was historically limited to the south of France, and which is gradually being observed in the north ...

Opinion and report of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) on the assessment of the impact of fox population dynamics on public health

open access: yesFood Risk Assess Europe, Volume 3, Issue 2, April 2025.
ABSTRACT The Red Fox (Vulpes vulpes) can be hunted as a game species. It may also be listed as a “species likely to cause damage” (ESOD – the acronym in French), for public health reasons among others. Conversely, benefits linked to the presence of foxes are also put forward, such as the predation of rodents carrying zoonotic agents.

Why are there so many definitions of eutrophication?

open access: yesEcological Monographs, Volume 94, Issue 3, August 2024.
Abstract Because of the first observations in the 1900s of the oligotrophic and eutrophic states of lakes, researchers have been interested in the process that makes lakes become turbid because of high phytoplankton biomass. Definitions of eutrophication have multiplied and diversified since the mid‐20th century, more than for any other ecological ...

Enhancing Osteogenic Potential in Bone Tissue Engineering: Optimizing Pore Size in Alginate–Gelatin Composite Hydrogels

open access: yesAdvanced Engineering Materials, Volume 26, Issue 13, July 2024.
Alginate and gelatin hydrogels are used in bone tissue engineering for their biocompatibility and 3D structure. This study shows that the hydrogels produced by freeze‐thaw cycles with 650 μm pores (3A5G) significantly enhance osteogenic differentiation compared to 350 μm pores (4A6G).

Is our understanding of aquatic ecosystems sufficient to quantify ecologically driven climate feedbacks?

open access: yesGlobal Change Biology, Volume 30, Issue 6, June 2024.
Life influences global climate by modulating Earth's atmospheric composition (which determines its greenhouse effect) and reflectivity (which determines its capacity to absorb solar heat). As human‐induced climate change reshapes environments on our planet, so too will changes in ecosystem structure and function alter climate.
