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 ...
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 ...
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.
Ciscoes are culturally and socio-economically ...
Drought effects on soil enzyme activity
(2021)
Soil extracellular enzyme activity (EEA) is a strong predictor for soil health. EEA cycle
nutrients within terrestrial systems, processing carbon, nitrogen, and phosphorous, while also
mineralizing and stabilizing gas. ...
Climate change impacts on the health and livelihoods of Indigenous communities in Northern Ontario
(2021)
Climate change is expected to affect people’s health and livelihoods in northern
Indigenous communities more adversely than in others due to existing socio-economic
conditions and direct reliance on the environment 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 ...
Interactive effects of elevated CO2 and temperature, nutrition, and ectomycorrhizas on morphological traits and summer shoot formation in jack pine
(2022)
Understanding the responses of trees, ectomycorrhizal fungi (ECM) and their association to
climate change can be challenging due to their interactions with multiple environmental factors.
The combined impacts of elevated ...
