The regeneration niche of white spruce following fire in the mixedwood boreal forest [PDF]
Silva Fennica, 2002 Early establishment of white spruce (Picea glauca) in mixedwood boreal forest stands following fire was examined at several times-since-fire (1-, 2-, 4-, 6-, 14-years). Abiotic and biotic conditions in the stands were assessed at two scales, tree plot

The Forestry Chronicle, 2023 Mixedwood stands, dominated by trembling aspen (Populus tremuloides Michx.) and white spruce (Picea glauca (Moench) Voss), are an important fibre source in Canada’s boreal forest and provide a range of ecological services. We present results from a study

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.
