Assessing above- and belowground competitive effects in pure and mixed stands of jack pine (Pinus banksiana) and black spruce (Picea mariana)
(2009)Ecological principles of niche, competition and competitive reduction suggest that competition in mixed stands composed of pine and spruce may experience positive interactions through (1) vertical stratification of canopy ... -
Charcoal in North American boreal forests: implications for carbon storage and management
(2014-01-22)Charcoal plays an important role in boreal soil function and carbon storage, and is present in most boreal forest soils as a result of naturally recurring wildfires. Charcoal management has been proposed as a potentially ... -
Growth and photosynthetic responses of white spruce seedlings to levels of trembling aspen and red raspberry cover
(2012-11-10)The effect of competitve species upon crop tree regeneration and growth continues to receive attention from researchers due to the importance of the outcomes. This study stakes a new approach, by examining the combined ... -
Impact of biochar and industrial ash amendments on soil properties, growth and nutrition of black and white spruce seedlings in a sandy loam soil
(2014)The purpose of this study was to establish and examine a controlled field experiment near Thunder Bay, Ontario using industrially produced ash and biochar as a soil amendment. This study monitors the change in physical, ... -
The Influence of site type and harvest intensity on understory composition in boreal Picea mariana (Mill.) B.S.P. forest communities in Northwestern Ontario
(2015-08-05)Plant diversity and composition in boreal black spruce understory communities was assessed 15 years after the application of three harvest disturbance treatments on loam, sand and peat site types. The study was carried out ... -
Investigating productivity and foliar nutrient status in second growth white spruce (Picea glauca) and trembling aspen (Populus tremuloides)
(2012-11-10)This thesis synthesizes two related papers investigating competitive interactions of second growth white spruce (Picea glauca [Moench] Voss) and trembling aspen (Populus tremuloides Michx.) at the Fallingsnow Ecosystem ... -
Moisture reduction and nutrient retention associated with field-drying forest harvest residues on clearcut sites in Northwestern Ontario, Canada
(2012-11-10)The increased utilization of forest harvest residues as supplemental, inexpensive and renewable energy raises two key concerns: 1) continued removal may negatively affect long-term site productivity; and 2) because 50-60% ...
