Effects of species mixtures on fine root production in a young boreal forest
(2019)1. Fine roots (< 2 mm) play a key role in terrestrial ecosystem processes. Species diversity loss has been recognized as one of the primary global change drivers that can have profound negative effects on ecosystem ... -
The estimation of boreal forest properties using spectral indices
(2018)The field of forestry has evolved to meet several objectives, including timber and other forest product production, tourism and recreation, habitat and wildlife management and climate change monitoring. As the field ... -
Fire disturbance mapping in a northern boreal forest using AVHRR/NDVI imagery : comparing techniques of change detection and substrate correction
(2000)Ontario’s landmass north of 51° latitude has been designated as the least intensively managed zone with respect to fire protection. Consequently, large natural fires dominate the boreal landscape. This northern zone, ... -
Foliar nutrient resorption and litterfall production with stand age, overstory composition, and disturbance origin in boreal forests
(2015-01-13)Nutrient resorption (NuR) prior to developmental senescence allows for nutrient conservation in plants, driven primarily by genetics, development stage, climate and soil fertility, and litterfall is the vector for the ... -
Global environmental change effects on forest dynamics: lessons from permanent sample plot networks
(2019)Global environmental change caused by anthropogenic emissions of greenhouse gasses is a major threat to forest ecosystems globally. Before we can begin to adequately mitigate these threats, we first must understand how ... -
Habitat use by woodland caribou in a managed boreal forest landscape
(2012-11-10)Woodland caribou (Rangifer tarandus caribou) populations throughout much of the boreal forest have decreased as a result of changes to forest composition, including an increase in moose (Alces alces) and wolf (Canis lupus) ... -
Impacts of invasive earthworms on carbon storage in southern boreal hardwood forests
(2017)The introduction of invasive, non-native earthworms into forest ecosystems has increased as recreational, industrial, and commercial activities increase in northern Ontario. The presence of these ecosystem engineers in ... -
Influence of fire, logging, and overstory composition on understory abundance, diversity, and composition in boreal forests, Ontario Canada
(2006)Study area : Northwestern Ontario -
Influence of riparian harvesting on boreal understory vegetation
(2014-01-22)In the boreal forest, understory vegetation accounts for the majority of floristic diversity and affects overstory succession and productivity, nutrient cycling, and wildlife habitat. In riparian forests, understory ... -
Introduction to the legacy forest small streams study : runoff patterns and related biogeochemistry on the western portion of the boreal shield
(2007)The Forest Watershed and Riparian Disturbance (FORWARD) Project is an ongoing study initiated on the western Boreal Plain (northwestern Alberta) in 2001 to incorporate hydrologic processes into industrial forest management. ... -
Lichen detectability under varying canopy closure
(2019)Monitoring lichen distribution is of increasing concern as mapping is critical in characterizing habitat for woodland caribou. Aerial photography collected using drones, the method used for this study, is a common method ... -
Limitations of forest overstory composition and age as proxies for habitat in a harvested boreal forest
(2014-12-11)Despite the importance of wildlife habitat protection in meeting land use management objectives, criteria for habitat identification are surprisingly amorphous. For example, while much current habitat modeling has tended ... -
Living landscapes of Granville Lake, Manitoba
(2012-11-10)This thesis addresses aspects of indigenous knowledge held by members of the community of Pickerel Narrows, located on Granville Lake, Manitoba as part of a larger community-based heritage research project led by Kevin ... -
Modelling the radial and longitudinal variation in wood density and its sensitivity to climate in black spruce (Picea mariana (Mill.) B.S.P.)
(2014-01-22)Wood density variation affects structural timber performance and is correlated with different sources (genetic diversity, stand dynamics and climatic effects) which, to date, have not been comprehensively quantified in ... -
Ojibway plant taxonomy at Lac Seul First Nation, Ontario, Canada
(2000)The Ojibway (Anishinabe) of Lac Seul First N ation reside in the transition zone of the Great Lakes-St. Lawrence and southern Boreal Forest regions of northwestern Ontario, Canada. Hunting and gathering of certain animal ... -
Past and future impacts of climate change on boreal forest timber supply
(2018)The boreal forest is home to a thriving forest industry which requires stable, long term timber to remain viable. Anthropogenic climate change, caused by the release of greenhouse gasses, is occurring rapidly in northern ... -
Patterns and mechanisms of epiphytic macrolichen and abundance, diversity and composition in boreal forest
(2014-12-11)Epiphytes are important components of the forest ecosystem, but the mechanisms that control epiphyte diversity are not clear. Epiphytes are sensitive to disturbance, but their responses to stand-replacing fire are poorly ... -
Patterns and mechanisms of understorey vegetation associated with stand development in boreal forests
(2018)The understorey vegetation comprises the greatest plant diversity and contributes substantially to ecosystem functioning and services in boreal forests. Although many studies have examined patterns of understorey species ... -
Plant abundance, diversity, and composition following reclamation in Alberta's oil sands
(2014-12-18)The Alberta oil sands have caused an economic boom in the Canadian economy in recent years. Identifying the best strategy for vegetation recovery after oil sands extraction is critical to restoring the biodiversity and ...
