The economic feasibility of replacing diesel with renewable energy resources in remote First Nation communities in Northern Ontario
(2017)Ontario has many First Nation communities in the remote northern region that use diesel fuel to generate part or the whole of their energy requirements. There is a huge financial and environmental cost associated with ... -
Effect of boreal forest disturbance due to logging at different spatial scales on migratory songbirds
(2024)Boreal birds have experienced population declines that may be related to alteration of the forest at a range of scales. Understanding how resource extraction may affect the distribution and abundance of species is critical ... -
Effects of CO2 elevation on the responses to flooding in black spruce (P. mariana) and tamarack (L. larcina) seedlings
(2016)Anthropogenic activities have been increasing the atmospheric CO2 concentration globally and the increase is predicted to continue to rise in the future. Increased CO2 has been shown to increase photosynthetic rates as ... -
Effects of nitrogen supply on the physiological and morphological responses to elevated [CO2] in yellow birch (Betula alleghaniensis Britt.)
(2023)Ongoing climate changes can substantially impact soil nitrogen availability through its effects on other environmental conditions such as temperature, precipitation, and the frequency and intensity of extreme whether ... -
Effects of Photoperiod, Soil Moisture and Soil Temperature on the Northward Migration Potential of Jack Pine under the Scenario of Doubled Atmospheric CO2 Concentration
(2016)Climate envelope models predict that boreal trees can potentially migrate northward by as much as 10º by 2100 as a consequence of the predicted climate change associated with the doubling of atmospheric CO2 concentration, ... -
The effects of soil compaction on the germination and growth of Picea mariana and Pinus banksiana
(2020)Soil compaction has long been an issue for the forestry industry. Soil compaction can reduce soil aeration, porosity and drainage, and restrict the growth and success of trees and other plants. The objective of this study ... -
Effects of water availability, longer photoperiod, and elevated [CO2] on the potential of the northward migration in trembling aspen (populus tremuloides michx.)
(2019)Based on climate envelope models, boreal tree species may migrate to higher latitudes (approximately 10˚N toward the north) in response to rapid climate changes by the end of this century. Multiple factors will likely ... -
Enabling community forestry in Northern Ontario
(2018)The forestry crisis that crippled the forest industry in northern Ontario in the new millennium led to a province wide forest tenure reform that created new forest governance institutions and a resurgence of a long-standing ... -
Environmental and economic impact assessment of biochar-based bioenergy production in Northwestern Ontario, Canada
(2016)Bioenergy is becoming very popular in Ontario with the 2014 ban on the use of coal in power generation. Biochar is produced as a by-product or a co-product of bioenergy. Past literature shows that if biochar is produced ... -
Estimating DBH with iPad Pro LiDAR in Boreal Forests: methodological considerations and a case study in natural boreal forests
(2024)Diameter at Breast Height (DBH) is the measure of the diameter of a tree stem 1.3 meters above the ground. DBH is a key variable measured in Forest Resource Inventories (FRIs) and is traditionally measured manually, which ... -
Exploring food system assessments as a contribution to sustainability and equity: a case study of the Thunder Bay + area food strategy community food system report card
(2023)The corporate food regime has contributed to a number of negative outcomes that include land, water, and ecosystem degradation; human health concerns; marginalization of smallholder farmers and urban agriculture producers; ... -
Exterior characteristics and internal wood decay of hazard trees in Thunder Bay, Ontario
(2013)One major component of urban forestry is the ability to recognize hazard trees and have them removed before they fail or cause damage to people or property. Thunder Bay's urban forest consists of approximately 20,000 street ... -
First Nation observations and perspectives on the changing climate in Ontario's Northern Boreal: forming bridges across the disappearing "Blue-Ice" (Kah-Oh-Shah-Whah-Skoh Siig Mii-Koom)
(2017)Forests can have significant potential to mitigate climate change. Conversely, climatic changes have significant potential to alter forest environments. Forest management options may well mitigate climate change. However, ... -
A functional trait analysis of successional pathway dynamics
(2018)The study of plant community re-assembly following disturbances in anthropogenically managed landscapes is a necessity in today’s climate. The measurement of plant functional traits is a tool that can be of great help in ... -
Genetic diversity and colonization patterns of Onnia tomentosa and Phellinus tremulae (Hymenochaetaceae, Aphyllophorales) in the boreal forest near Thunder Bay, northwestern Ontario
(2016)Forest health is impacted greatly by fungi, particularly those that cause disease in living trees. By examining genetic diversity within populations of pathogenic fungi and their patterns of colonization it is possible to ... -
Genetic variation of functional traits related to drought tolerance in yellow birch seedlings
(2022)Understanding patterns of variation in drought-related traits of hardwood trees is crucial for conserving and managing North American temperate forests under climate change. In this study, I examined provenance variation ... -
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 ... -
Herpetofauna in Rondeau Provincial Park, Ontario, Canada: comments on sample methodology and forest disturbance
(2022)Habitat selection in herpetofauna in Rondeau Provincial Park (RPP) around roads and human structures in built areas were described alongside recommendations on cover board material for their survey. The first objective ... -
Holocene fire-climate-vegetation dynamics in Central Canadian Shield boreal forests of Northwestern Ontario, Canada / by Dominic Lafontaine-Senici.
(2014)The boreal forest is the largest terrestrial ecosystem in North America, one of the least disturbed by humans, and most disturbed by fire. This combination makes it an ideal system to explore the environmental controls on ... -
How forests and forest management messaging was disseminated in governmental promotional material in Ontario, 1800–1959
(2020)This dissertation studies governmental forestry promotional publications issued in Ontario, to examine how messaging of forests and forest management was disseminated in promotional publications released by government ...
