Analysis of current and future Low Impact Development sites in Thunder Bay, Ontario
(2017)The rapid spread of urbanization in Thunder Bay has caused the increase of impermeable surfaces and the increase in flood incidents within the city. Another contributing factor to increased flood incidents is due to the ... -
The antifeedant action of climacodon septentrionalis and two species of sphaerobolus to hyphal grazing by the fungus-feeding nematode aphelenchoides sp.
(2012-11-10)Fungi are ubiquitous in forest ecosystems and are, collectively, a major force in driving nutrient and organic matter availability and cycling. Some saprotrophic and mycorrhizal fungi are characterized by a perennial ... -
A case for the commercial harvest of wild edible fungi in Northwestern Ontario
(2020)This undergraduate thesis explores the feasibility of a commercial wild edible mushroom industry in Northwestern Ontario. Commercially relevant fungi reviewed in this thesis include chanterelles, matsutake, boletes, ... -
A comparison of decomposition of jack pine and trembling aspen wood blocks by eight wood decay fungi
(2017)Decay is an important component of the carbon cycle, as it breaks down wood and releases the stored carbon back into the atmosphere. White rot, brown rot, and soft rot are all types of decay which initiate this process. ... -
An economic analysis of the impact of the Bronze Birch Borer on birch trees in Thunder Bay, Ontario
(2022)Urban street trees provide many ecosystem services, environmental and economic benefits for residents, communities, cities, and municipalities. The economic benefits of trees are not easily quantified as they have no ... -
Economic risk analysis of the Bronze Birch Borer on the Thunder Bay campus of Lakehead University
(2024)Urban forests serve many purposes to a city, from parks to street trees to crown cover in downtown cores. Trees in urban environments are more prone to stress and pathogen due to the environment in which they live. Birch ... -
Economic risk analysis of the emerald ash borer on the Thunder Bay campus of Lakehead University
(2018)In addition to their beauty, these trees contribute valuable ecosystem services. As of June 2016 the emerald ash borer, an invasive beetle from Asia, has been found in Thunder Bay and has the potential to kill every ash ... -
The effect of ectomycorrhizal fungus Hebeloma longicaudum on drought stress of Pinus banksiana seedlings
(2023)This study looks at the influence of the ectomycorrhizal fungus Hebeloma longicaudum to form associations and impact growth of jack pine seedlings under simulated drought conditions. Four treatment groups of jack pine ... -
Efficacy of MYKE® on in vitro growth of American elm (Ulmus americana)
(2017)This thesis is an examination of the commercial product MYKE which is a perlite-peat mixture containing 7 spores/g of Glomus intraradices N.C Schenk & G.S. Sm., a vesicular-arbuscular mycorrhiza-forming fungus. Seeds of ... -
An Examination of bark beetles and their associated blue stain fungi on boreal jack pine (Pinus banksiana) and white spruce (Picea glauca) in the Thunder Bay Region
(2009)Blue stain, caused by members of the Ophiostomatales, is of concern to the forest industry because it can quickly devalue timber by penetrating deep into the sapwood and creating dark blue to black staining. These fungi ... -
Examination of species of wood decay fungi present on hazard street trees in Thunder Bay, Ontario
(2018)Urban forests are an integral component in modern day urban infrastructure. Forests systematically planted in unnatural growing conditions are predisposed to injury, deficiency and disease, therefore requiring regular ... -
An examination of the effectiveness of MYKE® on growth of potted American elm seedlings under greenhouse conditions
(2018)This thesis is an examination of the commercial mycorrhizal additive known as MYKE®, and the impact upon growth that it has on American elm seedlings grown under greenhouse conditions. Seedlings of American elm were grown ... -
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 ... -
Fungi associated with the emerald ash borer on urban green ash
(2018)The emerald ash borer (Agrilus planipennis) is an invasive beetle recently introduced from Asia. It has quickly spread throughout much of eastern North America causing death of millions of ash (Fraxinus spp.) in both natural ... -
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 ... -
Health and management of trees planted in tree pits in Thunder Bay’s downtown north core
(2024)A survey of Thunder Bay’s downtown north core (formerly known as Port Arthur) examined 276 trees in an attempt to correlate the size and health condition of the trees with the size of the planting site. The largest and ... -
The impact of a fungus-feeding nematode (Aphelenchoides sp.) on decomposition of trembling aspen wood by various wood-decay fungi
(2018)Grazing by fungus feeding invertebrates on fungal mycelium can potentially impact many important ecological processes such as the formation of mycorrhizas and the decomposition of wood and litter. A study was initiated to ... -
Implementing a tree pruning cycle into the city of Thunder Bay
(2021)Several cities in Ontario and across Canada were contacted regarding their tree pruning programs. Of the ten from Ontario that responded, seven had a cyclical tree pruning program. Annual budgets ranged from $50,000 up ... -
