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 ... -
Black spruce (Picea mariana [Mill.] B.S.P.) boreal ecosystems : how tree-length and full-tree harvesting affects soil microbial populations
(2000)To evaluate the hypothesis that microbial populations are affected by organic biomass removals, a study was designed to complement ongoing work in a black spruce {Picea mariana [Mill.] B.S.P.) Boreal ecosystem. The ... -
Carbon and nitrogen dynamics associated with post-wildfire stand development of boreal mixed conifer ecosystems : application of data in model validation and refinement
(2006)Study site : Northwestern Ontario -
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 ... -
An examination of forest-dwelling birds in recreational areas within Thunder Bay, ON.
(2018)Forest-dwelling birds hold various social, economic, and ecological values. This study aims to identify the habitat elements that recreational areas provide or lack for various forest birds. Three recreational areas across ... -
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 ... -
Is habitat management in northwestern Ontario meeting the physiological needs of moose in the fall and early winter?
(2021)This thesis explores the question of whether the habitat management guidance provided by the Forest Management Planning Manual in Ontario is meeting the physiological needs of moose in the fall and early winter. Moose ... -
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% ... -
Potential of modeling to predict the re-establishment of bat populations affected by white-nose syndrome in northwestern Ontario
(2021)Since the first confirmed case in North America in 2007, white nose syndrome caused by Pseudogymnoascus destructans has decimated bat populations in the northeastern US and eastern Canada. Ontario is home to eight species ... -
Quantitative metrics of deadwood decay classes as a function of moisture regime and tree species
(2017)The patterns and rates of decomposition of dead woody debris (DWD) in the boreal ecosystem throughout the wood decay process have been hypothesized to vary across moisture regimes and between species. A fundamental aspect ...
