Patterns of cross-continental variation in tree seed mass in the Canadian Boreal Forest. [PDF]

PLoS ONE, 2013
Seed mass is an adaptive trait affecting species distribution, population dynamics and community structure. In widely distributed species, variation in seed mass may reflect both genetic adaptation to local environments and adaptive phenotypic plasticity.

Role of Mixed-Species Stands in Attenuating the Vulnerability of Boreal Forests to Climate Change and Insect Epidemics

Frontiers in Plant Science, 2021
We investigated whether stand species mixture can attenuate the vulnerability of eastern Canada’s boreal forests to climate change and insect epidemics.

Probability of Spring Frosts, Not Growing Degree-Days, Drives Onset of Spruce Bud Burst in Plantations at the Boreal-Temperate Forest Ecotone

Frontiers in Plant Science, 2020
Climate warming-driven early leaf-out is expected to increase forest productivity but concurrently increases leaf exposure to spring frosts, which could reduce forests' net productivity.

Black spruce extracts reveal antimicrobial and sprout suppressive potentials to prevent potato (Solanum tuberosum L.) losses during storage

Journal of Agriculture and Food Research, 2021
Canadian forest residues, such as bark, are an abundant and accessible biomass currently burned to produce energy, therefore neglecting their great potential for various applications owing to their multiple biological properties.

Genetics and Breeding of Black Spruce and Red Spruce

The Forestry Chronicle, 1969
This review emphasizes findings that are of value for early application in tree breeding and silviculture. Black spruce and red spruce are closely related genetically and hybridize where their ranges overlap, particularly in the Maritime Provinces.

Black spruce assimilates nitrate in boreal winter [PDF]

Tree Physiology, 2018
Winter has long been considered a dormant season in boreal forests regarding plant physiological activity such as nutrient acquisition. However, biogeochemical data clearly show that soil can remain unfrozen with substantial rates of nutrient transformation for several weeks following autumn snowfall.

Enhancing genetic mapping of complex genomes through the design of highly-multiplexed SNP arrays: application to the large and unsequenced genomes of white spruce and black spruce

BMC Genomics, 2008
Background To explore the potential value of high-throughput genotyping assays in the analysis of large and complex genomes, we designed two highly multiplexed Illumina bead arrays using the GoldenGate SNP assay for gene mapping in white spruce (Picea ...

Reflectance of Alaskan black spruce and white spruce foliage in relation to elevation and latitude [PDF]

Tree Physiology, 2003
Leaf reflectance at visible and near-infrared wavelengths (400-1000 nm) is related primarily to pigmentation, leaf structure and water content, and is an important tool for studying stress physiology and relationships between plants and their growth environment.

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 ...

The effects of fire on the thermal stability of permafrost in lowland and upland black spruce forests of interior Alaska in a changing climate

Environmental Research Letters, 2013
Fire is an important factor controlling the composition and thickness of the organic layer in the black spruce forest ecosystems of interior Alaska. Fire that burns the organic layer can trigger dramatic changes in the underlying permafrost, leading to ...
