Ecophysiological adaptations of black spruce (Picea mariana) and tamarack (Larix laricina) seedlings to flooding.

, 2004
Black spruce and tamarack are the predominant tree species in boreal peatlands. The effects of flooding on morphological and physiological responses were investigated in greenhouse grown (18 months old) black spruce (Picea mariana) and tamarack (Larix ...

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

Distinction anatomique du bois du mélèze (Larix laricina [Du Roi] K. Koch), de l'épinette blanche (Picea glauca [Moench.] Voss), et de l'épinette noire (Picea mariana [Mill.] B.S.P.), en vue de l'analyse des macrorestes

, 2000
Eighty-four specimens of wood collected in northeastern North America from pre-identified conifers were used to define new anatomical criteria to distinguish woody macroremains of Picea mariana, Picea glauca and Larix laricina.

Dynamics at the treeline: differential responses of Picea mariana and Larix laricina to climate change in eastern subarctic Québec

Environmental Research Letters, 2012
Treelines are known to be temperature-sensitive ecotones, and therefore could rapidly expand their range limits in response to climate warming. Observations of lack of range expansion, however, indicate that ecological constraints partly control the ...

Using LiDAR to quantify, map, and conserve late‐successional and old‐growth forest in Maine, USA

Ecosphere, Volume 17, Issue 6, June 2026.
Abstract The world continues to lose late‐successional and old‐growth (LSOG) forest as the human population and demand for wood fiber grow. However, older forest age classes provide structural and compositional characteristics important to biodiversity that are often not present in forests managed for timber.

Variation in reproductive potential across a multi-species treeline

Arctic, Antarctic, and Alpine Research, 2018
Cone and seed production at the forest-tundra ecotone, or treeline, depend on species-specific tolerances to limiting abiotic and biotic factors. As range expansion via seed dispersal is needed to keep pace with climate change, reproductive limitations ...

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.

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
