Short‐term soil responses and site conditions to inverted mounding on peatland linear features in Alberta, Canada

Restoration Ecology, EarlyView.
Abstract Introduction Seismic lines represent one of the most extensive and persistent anthropogenic disturbances in boreal peatlands, limiting forest regeneration and altering key ecosystem functions. Inverted mounding is increasingly applied to elevate planting microsites above shallow water tables, yet evidence on short‐ to medium‐term biophysical ...

Greenhouse Gas Reduction Potential Through Bioheat for Remote Communities in Northeastern Ontario

GCB Bioenergy, Volume 18, Issue 7, July 2026.
Heating infrastructure in remote areas has high potential for fuel switching, possibly leading to decreased greenhouse gas emissions. Using a simplified life cycle analysis approach, we show that woody residues from the forest industry have the potential to reduce greenhouse gas emissions compared to commonly used fossil fuels.

Glacial refugia, postglacial dynamics, and hybrid zones of Pinaceae in Eurasia captured from sedimentary ancient DNA

Ecosphere, Volume 17, Issue 6, June 2026.
Abstract Boreal forests cover nearly one‐third of global forest area. Glacial cycles have shaped the distribution and connectivity of modern Pinaceae genera, yet species‐level refugia, postglacial migrations, and hybridization patterns remain unclear due to limited high‐resolution taxonomic and temporal data. We applied a hybridization capture approach

An Evaluation of New Snow Interception and Ablation Parameterisations in Continental, Subarctic and Maritime Needleleaf Forests

Hydrological Processes, Volume 40, Issue 6, June 2026.
A new mass and energy balance for intercepted snow more accurately represented observations of subcanopy snow water equivalent and canopy intercepted snow load compared to an existing approach. The new CanSnow model also revealed how intercepted snowfall is partitioned between throughfall, sublimation, drip and unloading to the forest floor at two ...

Simulated Impacts of the 2023 Megadrought on Black Spruce Potential Productivity Across Canada

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Black spruce (Picea mariana) is a dominant tree species across the Canadian boreal forest and a key contributor to national carbon dynamics. However, its growth and stand productivity are increasingly threatened by intensifying droughts, rising temperatures, and associated disturbances such as wildfire. In this study, we used the process‐based

Résultats d’un délai d’application du dégagement mécanique en plantations d’épinettes blanche et noire dans un scénario de reboisement hâtif

The Forestry Chronicle, 2018
La maîtrise de la végétation concurrente est essentielle afin que les plantations présentent les rendements escomptés, mais ses effets dépendent de son moment d’application.

Contrasting Genomic Signatures of Climate Adaptation and Adaptive Plasticity Across the Distribution Ranges of Sessile Oak and European Beech

Molecular Ecology, Volume 35, Issue 11, June 2026.
ABSTRACT The persistence of organisms in changing climates depends on both phenotypic plasticity and adaptation. However, despite extensive research, it remains largely unclear how forest trees will genetically adapt or phenotypically acclimate to future climates.

Variability of Multispectral Lidar 3D and Intensity Features with Individual Tree Height and Its Influence on Needleleaf Tree Species Identification

Canadian Journal of Remote Sensing, 2018
Tree species identification is important in forest management. The multispectral lidar Titan of Teledyne Optech Inc. can improve tree species separation by providing classification features computed from the three-channel intensities, ratios and ...

Specifics of life cycle and damage of Oligonychus ununguis (Acari: Tetranychidae) on introduced species of coniferous plants in conditions of megalopolis

Persian Journal of Acarology, 2020
Population of the spider mite Oligonychus ununguis (Jacobi, 1905) was monitored on introduced species of coniferous plants in the Fomin Botanical Garden, Kyiv, Ukraine in 2012–2019.
