Natural Fire Regime: A Guide For Sustainable Management Of The Canadian Boreal Forest, Yves Bergeron, Alain Leduc, Brian D. Harvey, Sylvie Gauthier
Aspen Bibliography
The combination of certain features of fire disturbance, notably fire frequency, size and severity, may be used to characterize the disturbance regime in any region of the boreal forest. As some consequences of fire resemble the effects of industrial forest harvesting, conventional forest management is often considered as a disturbance that has effects similar to those of natural disturbances. Although the analogy between forest management and fire disturbance in boreal ecosystems has some merit, it is important to recognise that it also has its limitations. Short fire cycles generally described for boreal ecosystems do not appear to be universal; rather, …
Influence Of Forest Composition On Understory Cover In Boreal Mixedwood Forests Of Western Quebec, Sonia Legare, Yves Bergeron, David Pare
Influence Of Forest Composition On Understory Cover In Boreal Mixedwood Forests Of Western Quebec, Sonia Legare, Yves Bergeron, David Pare
Aspen Bibliography
Forest overstory composition influences both light and nutrient availability in the mixed boreal forest. The influence of stand composition on understory cover and biomass was investigated on two soil types (clay and till deposits). Four forest composition types were considered in this study: aspen (Populus tremuloides Michx.), paper birch (Betula papyrifera Marsh.), jack pine (Pinus banksiana Lamb.) and a mixture of balsam-fir (Abies balsamea (L.) Mill.) and white spruce (Picea glauca (Moench) Voss). The cover of all understory species was recorded while the biomass of two important and ubiquitous species was measured: mountain maple (Acer spicatum Lam.) of the shrub …
Vascular Plant And Epiphytic Lichen Communities In Canadian Aspen Parkland: Determinants Of Small-Scale Species Richness, H.L. Buckley
Vascular Plant And Epiphytic Lichen Communities In Canadian Aspen Parkland: Determinants Of Small-Scale Species Richness, H.L. Buckley
Aspen Bibliography
Within-community species-area relationships were examined for vascular plants and epiphytic lichens on Populus spp within 100 treed patches in an area of less than 4 km2 in the aspen parkland of south-central Alberta, Canada. Both plants and lichens were sampled on three scales (patch-scale and two within-patch scales). This study is one of the few to demonstrate scale-dependent species-area relationships at a small scale and highlights the importance of multi-scale sampling in ecology. At the larger patch scale, the relationship between plant species richness and area was positive for both the full plant dataset and the forest habitat specialist …
