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 ...
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, ...
Early growth responses of black spruce seed sources selected for reforestation under climate change scenarios in Ontario
(2014)
Study area : Northern boreal forest: (Northeastern - Sault Ste. Marie region) ; (Northwestern : Dryden and Kakabeka regions)
Comparative analysis of the properties of tamarack (Larix laricina (Du Roi) K. Koch) particleboard and thermally treated oriented strand board (OSB)
(2014)
Engineered wood products (EWPs), for example, particleboard and oriented strand board (OSB), are normally made from wood residuals or small particles of underutilized wood species for replacing solid sawn products as its ...
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 ...
The response of avian predator populations to forest tent caterpillar (Malacosoma disstria; Lepidoptera: Lasiocampidae) outbreaks in Ontario, Canada
(2020)
Outbreaks of insect defoliators have broad ecological effects on forested
ecosystems because they can cause extensive mortality in host tree
populations. They also represent peaks in the density of food for specialist ...

(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 ...
Diversity, phenology, and host associations of wild bees (Hymenoptera: Anthophila) in Thunder Bay, Ontario
(2020)
Although extremely important to the functioning of productive ecosystems, wild
bee communities are at risk due habitat loss and agricultural intensification. Wild bee
species surveys provide valuable information on the ...
Spatiotemporal effects of climate on the relationship between tree diversity and forest ecosystem functioning
(2020)
Worldwide, forest ecosystem functioning and plant diversity have been altered by global
environmental change. Understanding the relationship between biodiversity and ecosystem
functioning with long-term environmental ...
An investigation into the local and traditional knowledge of the Saugeen Ojibway Nation regarding the status of ciscoes (Coregonus spp.) in Lake Huron
(2020)
The ciscoes (Coregonus spp.) of Lake Huron are a poorly understood group of fish that have
experienced declines in population numbers and a collapse of their ecological communities.
