Effect of Organic Layer Thickness on Black Spruce Aging Mistakes in Canadian Boreal Forests
Boreal black spruce (Picea mariana) forests are prone to developing thick organic layers (paludification). Black spruce is adapted to this environment by the continuous development of adventitious roots, masking the root collar and making it difficult to age trees. Ring counts above the root collar underestimate age of trees, but the magnitude of age underestimation of trees in relation to orga...
متن کاملPartial and clear-cut harvesting of high-elevation spruce-fir forests: implications for small mammal communities
Subalpine spruce (Picea) -fir (Abies) forests Occur throughout the Cordillera of western North America. A variety of alternative silvicultural systems to clear-cutting are being investigated in these high-elevation forests in terms of their impacts on ecosystem components. We tested the hypotheses that abundance, reproduction, and survival of populations of (i) southern red-backed voles (Clethr...
متن کاملCarbon allocation in boreal black spruce forests across regions varying in soil temperature and precipitation
A common hypothesis for northern ecosystems is that low soil temperatures inhibit plant productivity. To address this hypothesis, we reviewed how separate components of ecosystem carbon (C) cycling varied along a soil temperature gradient for nine welldrained, relatively productive boreal black spruce (Picea marianaMill. [B.S.P.]) forests in Alaska, USA, and Saskatchewan and Manitoba, Canada. A...

متن کاملEctomycorrhizal fungal communities of black spruce differ between wetland and upland forests
Ectomycorrhizal (ECM) communities of black spruce (Picea mariana (Mill.) BSP) seedlings were characterized from three habitats spanning a moisture gradient in central British Columbia: black spruce dominated wetlands, black spruce – tamarack wetlands, and black spruce – lodgepole pine uplands. Morphological and molecular (PCRRFLP) analyses indicated a diverse community of root-associated ECM fu...
