Effects of the nitrogen deposition on the forest ecosystems: an overview
(2023)Human activities exacerbate the production and emission of reactive nitrogen and lead to the increase and globalization of nitrogen deposition. At present, the interference of human activities in the global nitrogen cycle ... -
Trends in breeding propensity of Common Loons (Gavia immer) in relation to lake water clarity in and around Algonquin Provincial Park
(2023)Productivity of Common Loons has been in decline across most of Canada for several decades. Many environmental factors and human impacts on the breeding grounds may be causing the decline, and these factors are known to ... -
Challenges with regenerating chipper debris pads: evaluating seedling performance nine years after planting
(2023)Debris from in-bush portable chain flail chippers can alter the abiotic environment factors within the mineral soil. Thus, chipper debris can create an unsuitable seedbed for seedling growth and survival. In this thesis, ... -
A review of silvics, stand dynamics, density management, and vegetation management in the Ontario boreal forest
(2023)Adaptive forest management requires constant re-evaluation of the efficacy and impact of current practices. Continuous development of information is key to any adaptive management regime, especially in the face of ... -
Evaluating the effects of clearcutting, wildfire, and bioenergy wood ash application on forest soils to improve emulation silviculture
(2023)Ontario’s forest management guides promote the use emulation silviculture to manage the province’s forests on a landscape scale based on natural disturbance regimes. While clearcut harvesting can have similar effects to ... -
Assessment of lake trout (Salvelinus namaycush) mercury concentration across a gradient of food web complexity and environmental variables
(2023)Exposure to mercury has been linked to health risks in both people and wildlife. In Ontario, mercury pollution is to blame for 85% of the consumption restrictions on fish from inland lakes. Heavy metals like mercury ... -
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 ... -
Wildlife management on urban golf courses: the case of the Ottawa Hunt and Golf Club
(2023)Urban development has put increasing pressure on public greenspaces and the local wildlife populations encompassing them. Golf courses are an accessible way for the public to view the natural environment and wildlife ... -
Driver and landscape-related factors associated with reported wildlife-vehicle collisions in Thunder Bay, Ontario
(2022)The ever-expanding road network in Ontario has created serious implications for wildlife and their movement within the province. This has led to the discovery of many factors that have the potential to increase the risk ... -
The invasion of garlic mustard in North America and control measures
(2022)The purpose of this report is to investigate the impact of garlic mustard invasion on forest and control measures. Invasive species often cause harm to local ecosystems. Garlic mustard is an invasive herb native to Europe ... -
Assessing the feasibility of low-cost unmanned aerial vehicle data collection and automatic tree detection to determine silviculture stand stocking status in BC
(2022)The objective of this research was to evaluate the capabilities and limitations of low-cost UAV-collected silviculture data derived from Digital Aerial Photogrammetric point clouds. Four regenerating forest stands with a ... -
A geospatial analysis and comparison of snow leopard and mountain lion habitat: implications for conservations and research
(2022)Big cats form an integral part of landscape ecosystem management and are vital to the persistence of natural habitats. Global change, alongside human interactions has severely harmed populations of these predators, often ... -
Application of Walki®Biomass cover as a better alternative to plastic mulching
(2022)Mulch is a material that works as a protective layer over the soil so as to retain water and prevent excess evaporation. They are either in the form of continuous sheets like plastic mulch or they come in a shredded form, ... -
Population genetics of caribou in the Brightsand range of Ontario
(2022)Boreal woodland caribou are listed as threatened in Ontario. This thesis examined whether the genetic diversity of boreal woodland caribou in the Brightsand Range differs comparing populations in portions of the range with ... -
The impact of environmental and ecological construction on the sustainable development of cities: a case study of Nanjing, Jiangsu Province, China
(2022)Today, urban development faces an ecological crisis. As a famous historical and cultural city in China, the contradiction between the morphological development of Nanjing and the ecological environment is becoming increasingly ... -
Production of wood pellets from forest product waste
(2022)Wood pellet production is increasing due to lower costs and supply stability as compared to natural gas and has less environmental concerns. A wood pellet is made mechanically from a uniform substance that has initially ... -
Updates from camera traps used to monitor the elk population in the Lake of the Woods area
(2022)Elk (Cervus elaphus L. canadensis), once widespread across North America, severely declined due to overhunting and habitat conversion in the 1900s. The Lake of the Woods are was one of four locations chosen to reintroduce ... -
Evaluating success of energy from algal biomass
(2022)This thesis explores the effectiveness of algal biomass as a possible alternative to fossil fuels. The thesis examines the cost-effectiveness, sustainability and environmental friendliness factors of algal biomass and ... -
Black bear attacks in Canada and a review of the factors influencing them
(2022)Canada has experienced numerous black bear attacks over the last several decades. The purpose of this study is to determine if there is an increase in the number of black bear attacks in Canada. Data came from various ... -
The history of deforestation in Southwestern Ontario and methods used in afforestation of old agricultural fields – a literature review
(2022)The forests of southwestern Ontario were logged in the 1700’s for use by the British and French navies as ship masts, spars and hulls. Early settlers cleared the forests to make way for agriculture and settlements. The ...
