Come from away: Reconstructing a long‐range migratory flight of spruce budworm moths to Newfoundland, Canada Venues de loin : reconstitution d'un vol migratoire de longue distance de tordeuses des bourgeons de l'épinette vers Terre‐Neuve, au Canada

Ecological Entomology, Volume 51, Issue 1, Page 41-58, February 2026.
Lagrangian atmospheric models were used in conjunction with ecophysiological factors to reconstruct the path and meteorological conditions of a long‐range migration flight of spruce budworm moths to Newfoundland, Canada. Moths travelled under high winds and warm temperatures that favoured their migratory flight until encountering cooler temperatures ...

Disentangling seed availability and establishment filters at alpine treelines through a decade‐long field manipulation

Journal of Ecology, Volume 113, Issue 12, Page 3830-3844, December 2025.
Treeline advance under warming occurs only when multiple filters align—adequate seed supply, favourable microclimatic windows, moderated herbivory and shrub effects that remain facilitative rather than competitive. Abstract Climate warming is expected to increase upslope shifts of alpine treelines globally.

Impact of obscured data on species distribution models

Conservation Biology, Volume 39, Issue 5, October 2025.
Abstract The lack of knowledge about geographic distribution and environmental preference can hinder conservation efforts for rare and threatened species. Open‐source databases provide an opportunity to address these knowledge gaps through the geographic information they hold on species worldwide.

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

Wood density variation across an Andes‐to‐Amazon elevational gradient

Journal of Ecology, Volume 113, Issue 9, Page 2370-2385, September 2025.
We study how wood density varies along a 3500‐m elevational gradient, spanning from the Andean tree line to the Amazon basin. Our results reveal that wood density decreases from low to mid‐elevations, then increases toward the tree line. These patterns underscore the influence of species composition, life forms such as tree ferns, and local ...
