Right on time: evaluating accuracy and timing of burn-severity assessments to support post-fire management

Abstract Effective wildfire impact assessment and post-fire management rely on burn-severity maps that accurately characterize fire effects on vegetation and soils. These maps inform time-sensitive activities such as post-fire flood and debris-flow modeling, risk mitigation for h...

Understanding forest soil degradation in Canada: threats, indicators and knowledge gaps

Canadian forests, encompassing approximately 367 million hectares, play an important role in global biodiversity conservation, carbon sequestration, hydrological regulation, and timber production. Nevertheless, these ecosystems are subjected to degradation pressures arising from...

Tree Species Vulnerability to Fire Increases at Dry Range Edge

ABSTRACT Plant responses to fire are generally characterized for individual species and thus do not capture the variation in responses that can occur geographically. Here, we examine post‐fire responses across the climatic range of multiple resprouting eucalypt species following...

The PtoERF1 ‐ PtomiR393a ‐ PtoFBL4 module confers drought tolerance via ABA –auxin crosstalk in Populus

Drought stress limits forest tree growth and adaptation, with xylem vessels critical for hydraulic transport and structural integrity. However, the molecular mechanisms of abscisic acid (ABA)-auxin interaction in regulating vessel morphogenesis under water-deficit conditions rema...

Life‐History Traits and Overwintering of Actia interrupta (Diptera: Tachinidae), a Larval Parasitoid of Choristoneura fumiferana (Lepidoptera: Tortricidae)

ABSTRACT Actia interrupta (Diptera: Tachinidae) is an important larval parasitoid of the eastern spruce budworm, Choristoneura fumiferana (Lepidoptera: Tortricidae), especially during low‐density (endemic) population phases. Despite its ecological importance, information on its b...
