The Root dynamics of mixed and single species stands in the boreal forest of central and eastern Canada
(2010)I examined trends of fine root biomass and necromass in different mixed- and single-species stands within the central and eastern regions of the North American boreal forest to determine how annual fine root production, ... -
Selecting locations for forest fuel treatments using simulation optimization
(2009)Wildfires in the Canadian boreal forest poses a considerable threat to forest inventory, structures and human lives. Traditional reactive methods of fire suppression fail to mitigate this threat and can worsen the problem ... -
Species diversity and aboveground productivity relationships in forest ecosystems
(2012-11-10)Empirical and theoretical studies have attributed the observed positive diversity-productivity relationship (DPR) across various ecosystems to a complementarity effect through niche differentiation and/or facilitation among ... -
Terrestrial lichen abundance in relation to stand structure and silvicultural history
(2014-01-22)Terrestrial lichen has been identified as an important factor contributing to suitable woodland caribou (Rangifer tarandus caribou) winter habitat. Conservation efforts to maintain viable populations of woodland caribou ... -
Testing local adaptation in five populations of Hyalella azteca in northern Alberta’s oil sands region
(2015)Canada’s oil sands hold the third largest petroleum reserves worldwide. Rapid economic growth has led to increased exploitation of the surrounding boreal forest despite limited understanding of the environmental effects ... -
Tracking habitat use by boreal toads in disturbed forest on the boreal plain in Alberta
(2014-12-05)Radio-telemetry is an effective way of collecting detailed information on the behaviour of a great many species. However, the presence of the radio-transmitter may influence the behaviour of the subject, an effect for which ... -
Using a novel methodology to test whether group size affects foraging behaviour in elk
(2012-11-10)Group formation is one of the most striking patterns in the natural world. Elk (Cervus elaphus and C. canadensis) are well known for their social and gregarious nature, but motivations for this behaviour are not fully ... -
Using coarse-scale physical lake characteristics to model lake sturgeon (acipenser fulvescens) feeding habitat and their prey
(2012)Coarse-scale, physical lake characteristics (lake fetch, shoreline exposure, and littoral-zone slope) were investigated as to their ability to predict benthic macroinvertebrate communities and lake sturgeon feeding along ... -
Using portfolio theory to evaluate the regional deployment of transferring tree seeds under uncertain future climates
(2012-11-10)In this study, the problem of deploying seed from multiple tree improvement orchards to multiple sites in an environment of uncertain climate change is addressed. A modeling approach is designed and applied with the objective ... -
Woody biomass-based bioenergy development at the Atikokan power generating station: local perceptions and public opinions
(2015-08-05)To tackle climate change, reduce air pollution and promote development of renewable energy, the Ontario government is investing in the conversion of the coal-based Atikokan Power Generating Station (APGS) in Atikokan, ...
