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 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 ... -
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 ... -
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 ... -
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 ... -
An inquiry into the fungal diversity associated with the galls formed by Pemphigus betae Doane
(2020)Leaves affected by galls induced by the aphid Pemphigus betae were collected from a Populus balsamifera tree located near the community garden on the campus of Lakehead University Thunder Bay. Out of the galls that were ... -
Invasive plant species management for the city of Thunder Bay

Mycoparasites and decay fungi: a study of their ecological interactions on wood blocks of Betula papyrifera
(2020)Decay fungi are an extremely important part of the forest ecosystem and provide essential ecosystem services including the breakdown of complex organic compounds and nutrient release. However, this important group of fungi ... -
An overview and update of low-impact developments (LIDS) in Thunder Bay
(2023)Climate change is accelerating at a rapid pace across the globe and with this, flooding in urban environments is also increasing. This means that there is and will be an increasing need for alternative methods of stormwater ... -
The potential uses of virus-infected symbionts to improve drought and heat stress in trees for improvement, climate change resilience, and restoration
(2023)With the rapid changes occurring to the climate of the boreal forest, many populations of trees are facing increased stresses and seeing lower productivity and survival. Conventional tree improvement programs take decades ... -
