Etude par capteur optique du dépôt formé lors de la filtration d'une suspension de bentonite sur fibre creuse [PDF]

, 1993
Lors de la filtration sur fibres creuses de suspensions de bentonite, il a été mis en évidence que le facteur limitant est la formation d'un dépôt à la surface de la fibre.Parlant de ces considérations, un dispositif optique a été mis au point pour ...

Recent vegetation shifts in the French Alps with winners outnumbering losers

Journal of Ecology, Volume 113, Issue 11, Page 3275-3292, November 2025.
Analysing 11 million records of 4250 French Alps plant species over 30 years shows that one‐third expanded their range, dominated by thermophilic and fast‐colonizing species, while 13% declined. Most species showed little response, with potential shifts lagging behind climate change. Our study deepens our understanding of the complex dynamics of recent

Approche inverse régularisée pour la reconstruction 4-D en tomographie dynamique sans compensation de mouvement [PDF]

, 2013
National audienceLa tomographie dynamique est la reconstruction, à partir de projections, d'objets induits d'un mouvement, le plus souvent périodique (e.g. le cycle respiratoire chez un patient).

Ecological factors underlying the spatiotemporal dynamics in a key forest beetle pollinator Facteurs écologiques à la base de la dynamique spatio‐temporelle d'un important coléoptère forestier pollinisateur

Agricultural and Forest Entomology, Volume 27, Issue 4, Page 590-599, November 2025.
Eusphalerum, an understudied beetle pollinator in North America, comprises over 50% of beetle specimens collected using flight‐intercept traps in forests across New Brunswick, Canada. In a study investigating its phenology, congeneric aggregation and population dynamics, we demonstrated that Eusphalerum exhibits unique phenology distinct from other ...

Predicting rare events using training data from stratified sampling designs, with application to human‐caused wildfire prediction

Canadian Journal of Statistics, Volume 53, Issue 3, September 2025.
Abstract Response‐based sampling is often used in modelling rare events from large, imbalanced data for efficiency. When modelling the event with logistic regression, the sampling design may be adjusted for using sampling weights or an offset. We propose a stratified sampling design for modelling rare events with large data which improves on previous ...

Evaluating patterns of plant phenological progression and pronghorn movement behaviors across diverse landscapes Évaluation des modèles de progression phénologique des plantes et des comportements de mouvement des antilopes d'Amérique dans divers paysages

Wildlife Monographs, Volume 218, Issue 1, September 2025.
We found variable spatial and temporal patterns and predictability of plant phenological progression across 8 pronghorn ranges in Montana. We sampled potential exposure to phenology values for migrants and residents along spring movement paths and summer ranges and found that within herds and years the resident and migrant movement strategies conferred

Aedes albopictus Is Rapidly Invading Its Climatic Niche in France: Wider Implications for Biting Nuisance and Arbovirus Control in Western Europe

Global Change Biology, Volume 31, Issue 8, August 2025.
Aedes albopictus is invading Western Europe, causing autochthonous cases of arboviral diseases. Through a mechanistic modeling framework, we simulated the impacts of climate changes on the extension of the area environmentally suitable for the presence of this vector and for the transmission of arboviruses.

Influence de la déforestation sur le fonctionnement hydrologique de petits bassins versants tropicaux [PDF]

, 1998
Les régions tropicales subissent une déforestation importante. En Amérique du Sud,la forêt est généralement remplacée par une prairie, C'est pourquoi nous avons étudié le comportement hydrologique de 2 petits (1,5 ha) bassins versants.

Long‐Term Temporal Divergence in Post‐Drought Resilience Decline Between Deciduous and Evergreen Tree Species

Global Change Biology, Volume 31, Issue 7, July 2025.
Severe drought increasingly threatens the resilience of forest biomes worldwide. Using a tree‐ring database from Canadian forests, encompassing 40,147 trees across 4558 plots and 23 species, we analyzed temporal and spatial patterns of drought resilience.
