Optimization of Bioactive Polyphenols Extraction From Picea mariana Bark [PDF]

open access: yesMolecules, 2017
Reported for its antioxidant, anti-inflammatory and non-toxicity properties, the hot water extract of Picea mariana bark was demonstrated to contain highly valuable bioactive polyphenols.

Near-saturated and complete genetic linkage map of black spruce (Picea mariana) [PDF]

open access: yesBMC Genomics, 2010
Background Genetic maps provide an important genomic resource for understanding genome organization and evolution, comparative genomics, mapping genes and quantitative trait loci, and associating genomic segments with phenotypic traits.

Exploring genomic variation associated with drought stress in Picea mariana populations [PDF]

open access: yesEcology and Evolution, 2020
Predicted increases in drought and heat stress will likely induce shifts in species bioclimatic envelopes. Genetic variants adapted to water limitation may prove pivotal for species response under scenarios of increasing drought.

Postglacial phylogeography, admixture, and evolution of red spruce (Picea rubens Sarg.) in Eastern North America

open access: yesFrontiers in Plant Science, 2023
Climate change is a major evolutionary force that can affect the structure of forest ecosystems worldwide. Red spruce (Picea rubens Sarg.) has recently faced a considerable decline in the Southern Appalachians due to rapid environmental change, which ...

Effects of invasion by birch on the growth of planted spruce at a post-extraction peatland [PDF]

open access: yesMires and Peat, 2020
Planting forest on cutover peatlands may be regarded as a viable restoration technique in western Canada, where natural bogs are treed with a high density of Black Spruce, Picea mariana. Fertilizer is needed to promote P. mariana establishment on cutover

Radial growth of subarctic tree and shrub species: relationships with climate and association with the greening of the forest-tundra ecotone of subarctic Québec, Canada

open access: yesArctic Science, 2023
Climate change has resulted in a widespread increase in primary productivity in northern regions. This “greening” can alter terrestrial ecosystems dynamics and trigger positive climate feedbacks, but often exhibits spatial heterogeneity. Few studies have

Bridging implementation gaps to connect large ecological datasets and complex models

open access: yesEcology and Evolution, 2021
Merging robust statistical methods with complex simulation models is a frontier for improving ecological inference and forecasting. However, bringing these tools together is not always straightforward.

Divergent responses to permafrost and precipitation reveal mechanisms for the spatial variation of two sympatric spruce

open access: yesEcosphere, 2021
The ranges of black and white spruce are largely sympatric, suggesting both species have similar climate requirements. The two species, however, are highly segregated across the landscape with black spruce most common on nutrient‐poor sites with cold ...

Variation, coordination, and trade-offs between needle structures and photosynthetic-related traits across five Picea species: consequences on plant growth

open access: yesBMC Plant Biology, 2022
Background Picea species are distributed and planted world-wide due to their great ecological and economic values. It has been reported that Picea species vary widely in growth traits in a given environment, which reflects genetic and phenotypic ...
