The Relationships Of Vegetation And Bird Communities With Landforms And Geomorphic Processes On The Central Niagara Escarpment (Ontario), Robert John Milne
The Relationships Of Vegetation And Bird Communities With Landforms And Geomorphic Processes On The Central Niagara Escarpment (Ontario), Robert John Milne
Theses and Dissertations (Comprehensive)
This study has examined the relationships between geomorphic form and process, vegetation composition and dynamics, and avian populations for landscapes in the central Niagara Escarpment, Southern Ontario. This includes an area extending from Speyside Conservation area near Milton to Mono Cliffs Provincial Park north of Orangeville. Data was collected for geomorphic form and process parameters, vegetation species and structural parameters, and avian species. The physical parameters included a combination of landform characteristics including slope angle, aspect, and landscape position and geomorphic processes, such as creep and debris slides, measured as a level of disturbance. Human levels of disturbance were also …
Developing A Conceptual System Model For Ecological Integrity Planning In The Greater Kluane Region, Yukon, Brent Heyward Parker
Developing A Conceptual System Model For Ecological Integrity Planning In The Greater Kluane Region, Yukon, Brent Heyward Parker
Theses and Dissertations (Comprehensive)
Understanding the complexity and ecological organization of protected area ecosystems, and their bioregional surroundings, is fundamental to maintaining their integrity. This research set out to integrate the bodies of systems and hierarchy theory to establish a framework for developing a conceptual model that would synthesize knowledge from diverse fields and identify key system processes, thereby providing new insight into ecosystem organization, function, and integrity. This understanding was then applied to planning for ecological integrity in the Canadian National Parks context through a case study of Kluane National Park and Reserve (KNP&R) within the Greater Kluane Region (GKR). The methodology characterized …
Variability Of Metals In Soils In The Sudbury Area (Ontario), Vera Spektor
Variability Of Metals In Soils In The Sudbury Area (Ontario), Vera Spektor
Theses and Dissertations (Comprehensive)
Industrial development influences the natural and human environment. At the local scale, the most intensive industrial pollution is in the area of factories and industrial centers. Industrial pollution is concentrated in soil and vegetation (then, using water systems and trophic chains it may enter all ecosystem components). The industrial pollution of the Sudbury region includes mostly sulfur dioxide and heavy metals. The main goal of this study was to examine spatial variability in metal distribution in soil for the Sudbury area. Objectives of the work were to describe metal distribution depending on geographic factors such as topographic location, vegetation cover, …
