Vascular Plant And Epiphytic Lichen Communities In Canadian Aspen Parkland: Determinants Of Small-Scale Species Richness, H.L. Buckley Jan 2002

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 …


Influence Of Forest Composition On Understory Cover In Boreal Mixedwood Forests Of Western Quebec, Sonia Legare, Yves Bergeron, David Pare Jan 2002

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 …
