Visual Recognition Software for Binary Classification and Its Application to Spruce Pollen Identification. [PDF]
PLoS ONE, 2016 Discriminating between black and white spruce (Picea mariana and Picea glauca) is a difficult palynological classification problem that, if solved, would provide valuable data for paleoclimate reconstructions.

Journal of Animal Ecology, EarlyView.Anthropogenic disturbances associated with mineral extraction influenced space use and activity patterns in grizzly bears, and to a much lesser extent in black bears, in a subarctic ecosystem, signalling an asymmetric response. Abstract Niche partitioning is an evolutionary process that allows the coexistence of multiple species in a landscape. However,

Tree growth response and adaptation to climate change and climate extremes: From canopy to stem
Journal of Integrative Plant Biology, EarlyView.This review synthesizes the responses and adaptations of tree growth, including canopy phenology, intra‐annual wood formation dynamics, and annual stem growth, to climate change and climate extremes. It highlights key knowledge gaps for future research to support sustainable forest management and enhance forest carbon storage under ongoing climate ...

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 ...

Black spruce (Picea mariana) seed availability and viability in boreal forests after large wildfires
Annals of Forest Science, 2023 Key message Black spruce (Picea mariana (Mill.) B.S.P.) has historically self-replaced following wildfire, but recent evidence suggests that this is changing.

Responses of black spruce (Picea mariana) and tamarack (Larix laricina) to flooding and ethylene [PDF]
Tree Physiology, 2003 Black spruce (Picea mariana (Mill.) BSP) and tamarack (Larix laricina (Du Roi) K. Koch) are the predominant tree species in the boreal peatlands of Alberta, Canada, where low nutrient availability, low soil temperature and a high water table limit their growth.

Terra Nova, EarlyView.ABSTRACT Annual tree‐ring oxygen‐isotope values were measured from sections of two fossil logs of Picea mariana (black spruce) recovered from last glacial maximum proglacial sediment in Illinois, USA. Collectively, the specimens date from ca. 25,130 to 24,720 cal years BP.

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.
