Stagewise crop yield prediction with multisource functional indices

Canadian Journal of Statistics, Volume 54, Issue 1, March 2026.
Abstract Index insurance design involves integrating weather data, soil moisture, phenology information, and satellite imagery, which presents challenges in data fusion. This article addresses the modelling of multisource functional indices of varying lengths by constructing a stagewise ensemble of sequential models.

Physiological roles of lignins – tuning cell wall hygroscopy and biomechanics

New Phytologist, Volume 248, Issue 6, Page 2674-2706, December 2025.
Summary Lignins constitute the second most abundant carbon‐storing biopolymers in the biosphere. These phenolic polymers accumulate in different concentrations, compositions, and localisations within and between cell wall layers and cell types. Lignins were acquired during plant terrestrialisation 450 million years ago, and the diversification of their

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

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 ...

État des lieux des représentations dynamiques des temporalités des territoires [PDF]

, 2014
Le temps et ses caractéristiques ont toujours fait l’objet de grandes attentions pour comprendre les dynamiques des territoires. Aujourd’hui, que ce soit à cause des nouvelles capacités d’observation en temps réel, de l’accumulation des séries de données

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.
