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

open access: yesAgricultural 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

open access: yesCanadian 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

open access: yesWildlife 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

open access: yesGlobal 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.

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

open access: yesGlobal 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.

Towards a better understanding of avian collision in wind energy facilities using automatic detection systems

open access: yesJournal of Applied Ecology, Volume 62, Issue 6, Page 1437-1448, June 2025.
Data from automatic detection systems are a promising non‐invasive approach that requires few human and logistical resources to develop a more comprehensive bird collision risk mitigation strategy. They can be valuable to biodiversity stakeholders to highlight environmental factors that locally increase bird exposure and sensitivity, to avoid ...

Querying Multigranular Spatio-temporal Objects [PDF]

open access: yes, 2008
The integrated management of both spatial and temporal components of information is crucial in order to extract significant knowledge from datasets concerning phenomena of interest to a large variety of applications. Moreover, multigranularity, i.e., the

Les variations spatio-temporelles de la (non) reconnaissance sociale du deuil périnatal

open access: yes, 2020
Stemming from a critical reflexion on the concept of disenfranchised grief (DG), this article examines the way (non) acknowledgement unfolds in the context of perinatal death/grief, along spatial and temporal lines. It was shown that acknowledgment tends to decrease as we move along the temporal axis (i.e.
