A Field Investigation Of Planimetric Knickpoint Morphology From Rock-Bed Sections Of Niagara Escarpment Fluvial Systems (Ontario), Richard Stanley Pyrce

Theses and Dissertations (Comprehensive)

This study was an initial attempt to understand the impact of parents, peers, the media, and sex education curricula on shaping adolescents' knowledge and attitudes about dating relationships and sexuality. In addition, participants' descriptions of what constitutes a "good" date and a "bad" date were investigated. One hundred participants (48 females, 52 males) aged thirteen to sixteen participated: half of the sample were early adolescents (13-14 years) and the other half were middle adolescents (15-16 years). All participants were asked to describe experienced or hypothetical "good" and "bad" dates. For "good" dates, respondents identified engaging in fun, recreational activities, whereas …

Hydrometeorological Investigations On A Small Valley Glacier In The Sawtooth Range, Ellesmere Island, Northwest Territories, Paul Michael Wolfe

Theses and Dissertations (Comprehensive)

Hydrometeorological techniques were employed during the summer of 1993 to study a small (4.7km2) valley glacier in the Sawtooth Range, Fosheim Peninsula, Ellesmere Island, Northwest Territories. The annual 1992-93 mass balance for Quviagivaa Glacier (unofficial name), and for the adjacent Nirukittuq Glacier (unofficial name) was -532mm and -530mm water equivalent respectively. The equilibrium line altitude was above the upper limit of the glaciers due to the exceptional warmth of the summer. Slight marginal shrinking in the areal extent of Quviagivaa Glacier since 1959 suggests that strongly negative mass balances such as those recorded in 1993 are not indicative of the …

The Volumetric Change Of The Peyto Glacier, Alberta, Canada, 1896-1966, Alistair Lennox Wallace

Theses and Dissertations (Comprehensive)

The historical information concerning the Peyto Glacier is plentiful, especially with regards to terrestrial photographs. The information available dates from 1896 to present day. The glacier has been studied intensively since the 1960’s. The purpose of this thesis is to document a comprehensive historical record and determine volumetric changes of the Peyto Glacier, 1896-1966.

Changes in the extent of Peyto Glacier, Alberta are determined for the period 1896-1966. Data sources used include terrestrial photographs of Peyto Glacier from 1896, 1902 and 1917, the 1917 Alberta-British Columbia Interprovincial Boundary Commission Survey map and the 1966 map of the Peyto Glacier produced …

Linking Landscape Ecology And Ecosystem Health: The Case Of Lunigiana, Italy, Susan Anna Pellanda

Theses and Dissertations (Comprehensive)

As ecosystem-based management is increasingly used to manage the environment, methods of applying these approaches to resolve environmental and natural resource issues must be established. The concept of ecosystem health can be used to assist in ecosystem-based management since it takes into account the environmental, economic, and social aspects of ecosystems. The aim of this thesis is to demonstrate the manner in which landscape ecology can be used to manage for the goal of obtaining a healthy ecosystem. This is achieved by studying the landscape of Lunigiana, Italy, an agricultural region located near Italy's northwestern coast. Particular emphasis is placed …

Opportunities For The Integration Of Institutional Arrangements For Riparian Buffer Zone Management In Ontario, Canada, Jeffrey Willard King

Theses and Dissertations (Comprehensive)

A need exists in Ontario for improved management of land and water resources. In addition the need for increased integration within and among the agencies responsible for these resources is imperative. Between these two resources is the riparian zone, for which riparian vegetative buffer zones are a recognized Best Management Practice (BMP) for water quality improvement. However, the problem remains that each agency views buffers from a particular perspective. Hence, butters are being implemented primarily for a single purpose without considering the multiple use of buffers. To achieve an integrated management framework for riparian buffers, it is necessary to evaluate …
