The genetic diversity of eastern North American tree species as related to the extent of their spatial distribution during the Last Glacial Maximum
(2020)The distribution of boreal and temperate species during the last glacial maximum (LGM) in Eastern North America can have a significant effect on the genetic diversity of present day populations. Here, I modelled the LGM ... -
Grazing intensity and carbon pools in soils, roots and forage plants on the Thunder Bay community pasture
(2020)This thesis explores carbon (C) storage in the forage plants found on the Thunder Bay Community Pasture (TBCP). Plant tissues, roots and shoots, were collected from the TBCP and analyzed at Lakehead University using a ... -
Habitat composition and spatial response of white-tailed deer to forestry treatments in moose range, Grand Portage Indian Reservation, Minnesota
(2020)Moose (Alces alces L.) have long been an important subsistence species are of great cultural value to the Ojibwe peoples. White-tailed deer (Odocoileus virginianus Z.) have been implicated in negatively impacting ecosystems ... -
Harvest productivity analysis based on stand boundary length of Weyerhaeuser’s Pembina Timberlands
(2022)Harvest productivity can be influenced by many different factors within a harvest block and knowing the impact of those factors allows harvest efficiency to be maximized. This thesis explored the effect that stand boundary ... -
Heavy metal pollution control technology - phytoremediation in China
(2017)As a worldwide problem, soil heavy metal pollution has a huge impact on human production and life. The world has invested a lot of manpower and material resources for environmental governance. Environmental pollution ... -
How does aquatic invertebrate community structure and abundance relate to brook trout (Salvelinus fontinalis) habitat quality?
(2019)Sixty-seven streams located south-west of Lake Nipigon, Ontario, were sampled for brook trout and macroinvertebrate orders. Sixteen orders were used to determine if their community structure significantly changed in different ... -
How Ontario’s managed forest tax incentive program (MFTIP) works, why it is useful, and its benefits to private landowners and the environment
(2021)The vast majority of Ontario’s forest is owned by the Province. However, most of the deciduous and Great Lakes- St. Lawrence forest is privately owned. Government has very little control over private land. To encourage ... -
How to achieve meaningful consultation/accommodation with First Nation communities: The need/benefits for community-led forest management plans in Ontario’s forest industry
(2022)The inherent Aboriginal and treaty rights of First Nations people continue to be infringed upon in Ontario’s forest industry. The province of Ontario continues to abuse its colonially obtained Section 92 powers and has ... -
Hydromapping Tool Creation for Sprat Lake Using Unmanned Aerial Vehicles (UAV) Surface From Motion Analysis; A Proactive Approach to Reduce Potential Mercury Fluxes Following Forest Harvesting By Using Variable Retention Buffers and Preplanned Machine Travel Corridors
(2017)There has been an increase in the awareness and concern regarding mercury contamination in Northwestern Ontario fish. Wetland and low laying areas are considered hotspots for methylmercury production which, when disturbed ... -
Impact and relation between proximity of two individual trees and their general development
(2021)The intend of the following study is to understand and analyse a trend which marks the relationship between proximity of two trees and their general development. In this study we will examine two types of regeneration ... -
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 ... -
The impact of climate change on the phenology of short- and long-distance migratory birds
(2021)Quickly changing temperatures due to climate change are expected to have devastating consequences on the migratory bird populations around the globe. However, surprisingly, several studies have demonstrated that some ... -
The impact of invasive thistle species on dynamics of Cercopidae in the Stikine-Skeena region of northern British Columbia
(2020)During the Summer of 2019 I worked on suppressing invasive species spread in the Stikine-Skeena region of Northern British Columbia. I frequently observed invasive thistle species of the genus Cirsium hosting abundant ... -
Impacts of different forest watershed composition factors on soil condition in upstream of Miyun Reservoir Watershed, nothern China and its current situation
(2020)This thesis explores the Miyun Reservoir Watershed’s soil condition and the current situation it faces now. Miyun Reservoir is located in northern Beijing and has more than sixty years of history. It is the primary water ... -
Impacts of different harvesting methods on forest environment
(2019)Harvesting methods are an important component of forestry management. Determining the impact of harvesting methods on forest environment can help us to do it more efficiently. In this paper, the methods, impact and intensive ... -
Impacts of invasive earthworms on carbon storage in southern boreal hardwood forests
(2017)The introduction of invasive, non-native earthworms into forest ecosystems has increased as recreational, industrial, and commercial activities increase in northern Ontario. The presence of these ecosystem engineers in ... -
The impacts unnatural foods have on hibernation and health in American Black Bears
(2021)As humans encroach more and more into wild spaces, we will continue to see an increase in the negative impacts our lives have on those of the animals we share these spaces with. One of these ways is through our food. In ... -
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 ... -
Increasing diameter growth content of red pine (Pinus Resinosa) through intensive management
(2017)Intensive forest management can only be justified if it increases wood quality or yield sufficiently to compensate for the additional investment. Treatments such as thinning and/or pruning are typically only applied to ... -
Industrial biochar characterization : properties and potential applications
(2021)Biochar is a carbon-rich charcoal produced from pyrolyzed biomass such as wood, agricultural waste, or animal products. Biochar is primarily used as a soil amendment, but it has promising applications in carbon sequestration, ...
