Fine Root Growth of Black Spruce Trees and Understory Plants in a Permafrost Forest Along a North-Facing Slope in Interior Alaska [PDF]
Frontiers in Plant Science, 2021 Permafrost forests play an important role in the global carbon budget due to the huge amounts of carbon stored below ground in these ecosystems. Although fine roots are considered to be a major pathway of belowground carbon flux, separate contributions ...

The spread of Kalmia angustifolia on black spruce forest cutovers contributes to the spatial heterogeneity of soil resources. [PDF]
PLoS ONE, 2018 Kalmia angustifolia is a boreal ericaceous shrub that can rapidly spread on black spruce forest cutovers in eastern Canada, where CPRS (i.e. Cutting with Protection of Regeneration and Soils") is practiced.

Impacts of fire on non-native plant recruitment in black spruce forests of interior Alaska. [PDF]
PLoS ONE, 2017 Climate change is expected to increase the extent and severity of wildfires throughout the boreal forest. Historically, black spruce (Picea mariana (Mill.) B.S.P.) forests in interior Alaska have been relatively free of non-native species, but the ...

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.

Highly informative single-copy nuclear microsatellite DNA markers developed using an AFLP-SSR approach in black spruce (Picea mariana) and red spruce (P. rubens). [PDF]
PLoS ONE, 2014 Microsatellites or simple sequence repeats (SSRs) are highly informative molecular markers for various biological studies in plants. In spruce (Picea) and other conifers, the development of single-copy polymorphic genomic microsatellite markers is quite ...

Does the type of silvicultural practice influence spruce budworm defoliation of seedlings?
Ecosphere, 2021 Spruce budworm (Choristoneura fumiferana (Clem)) is the main defoliator in the boreal forest of North America, and its outbreaks have major ecological and economic consequences and represent a challenge for forest management.

Fertiliser Addition Is Important for Tree Growth on Cut-Over Peatlands in Eastern Canada [PDF]
Mires and Peat, 2008 Fertilisation is considered essential for tree growth on cut-over peatlands. However, little research has been carried out on these managed ecosystems in North America. Two experiments were conducted on peatlands planted with black spruce (Picea mariana (

Ecosphere, 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 ...

The spruce budworm, a potential threat for Norway spruce in eastern Canada?
The Forestry Chronicle, 2020 Norway spruce, an exotic tree species in North America, was largely used in reforestation programs in the province of Québec between 1972 and 1990. Several of these plantations are now reaching their commercial maturity and the resurgence of spruce ...
