Constraints on the formation of depositional placer accumulations in coarse alluvial braided river systems
(1989)Placer accumulations are formed by the preferential sedimentation of heavy minerals from the general population of detritus being transported by a fluid. The depth, velocity, and grain size conditions under which placers ... -
Stratigraphy of two late paleozoic basins : implication for the timing of final emplacement of the Meguma terrane
(1990)Paleoraagnetic studies indicate the Meguma terrane's final emplacement occurred between the Mid-Devonian and Early Permian. Lithostratigraphic units near the boundary of the terrane were investigated in order to provide ... -
Public participation in community forests : the Ontario community forest pilot projects / by Florence Wanjira Chege.
(1994)Levels of public participation in the management of a community forest (CF) depend on the CF’s goals and the subsequent decision-making structure that the community adopts. To evaluate the hypothesis that the Ontario ... -
Simulation analysis of components of Ontario's moose habitat guidelines
(1994)The intent of Ontario's "Timber Management Guidelines for the Provision of Moose Habitat" is to use timber management to maintain or improve the moose habitat potential of a forest. In the boreal forests of Ontario, ... -
Long-term effects of timber management on marten (Martes americana) habitat potential in an Ontario boreal forest
(1993)To evaluate the hypothesis that current forest management practices in the boreal forest are decreasing the quantity and quality of long-term marten habitat, and alternative, more suitable strategies exist, a ... -
Trends and variability of temperature and precipitation in Northwestern Ontario during the 20th century : implications for forest management
(2000)Time series of temperature and rainfall in Northwestern Ontario are joined and adjusted to provide a database for analysis of regional climate change. Processes used to locate and adjust for non-climatic discontinuities ... -
Interfacing an aggregate wood supply model with a geographic information system
(1994)By developing a general interface between forest planning models and geographic information systems, the forest planner is capable of spatially analyzing the results of wood supply analysis. The planner can change the ... -
Ecosystem sustainability and resource-based tourism : linkages and indicators
(2000)The landscape of northern Ontario provides an ideal setting for resource-based tourism and, in recent years, the focus on tourism has increased due to the popularity of outdoor recreation and the notion that tourism can ... -
Implications of alternative herbicide-use policies for forest management in Ontario
(1995)Public sentiment is against herbicide use on public forests in Ontario. Provincial policies are directing research into alternative vegetation management with only limited interaction or support with forest resource based ... -
Regional environmental assessment of forest management : experience in Ontario and Minnesota
(1995)Environmental assessment (EA) was originally conceived as a process applying to discrete projects such as power dams and timber harvest plans, but increasingly it is being applied to programs and policies for large areas. ... -
Indicators of forest sustainability for Ontario boreal forests : a first approximation
(1995)If humankind is to cope with the cumulative effects of its expanding populations on the earth’s ecosystems, a new relationship is required with natural systems. Serious adoption of the concepts of forest sustainability ... -
Effects of water depth increases on the production and growth of wild rice, Zinzania aquatica L.
(1987)Wild rice, grown in plastic buckets suspended from specially designed rafts, was subjected to increases in water depth during the submerged-leaf, first floating-leaf, second floating-leaf, and the first aerial-leaf ... -
Growth of wild rice, Zizania aquatica L., in flocculent sediments
(1988)The objectives of this research were to classify sediments from wild rice lakes, and to examine, in detail, one type of sediment that is not suitable for commercial production of wild rice. Based on physical and chemical ... -
Effectiveness of dispute resolution mechanisms in natural resource management in Ontario
(1994)For a variety of reasons, the number and complexity of natural resource management conflicts in Ontario is increasing rapidly. To evaluate the premise that existing natural resource management planning processes are ... -
Use of wetlands to remediate gold mine effluent
(2000)The effluent from Musselwhite Mine was examined to determine the improvement to water quality as it passed through a treatment wetland prior to final discharge to the receiving water body. Potential toxicity problems ... -
Effects of perceived competence and goal orientations on task persistence and affect in physical activity : a test of Dweck and Leggett's motivation theory
(1990)This study tested Dweck and Leggett’s (1988) social cognitive model of motivation in the physical domain. It investigated the effects of perceived competence (PC) and goal orientation (GO) on affective and behavioral ... -
Mating system and population structure in a black spruce (Picea mariana (Mill.) B.S.P.) clonal seed orchard in Northwestern Ontario
(1985)Multi-locus enzyme systems were studied in a black spruce {Picea maniana (Mill.) B.S.P.) clonal seed orchard in northwestern Ontario. The embryonic and megagametophytic tissues of each clone were sampled and ... -
Coping and affect in performance by youth swimmers : an investigation of patterns of coping
(1993)The primary purpose of this study was to examine how young swimmers cope with the stress of sport during competition. Specifically, this study will examine if swimmers use a consistent coping style over three different ... -
Role of aquatic macrophytes in trophic status of Northwestern Ontario lakes
(1993)This research focusses on the development, refinement, and assessment of regional trophic status models for lakes of northwestern Ontario. Two companion papers describe the application of image analysis of aerial photographs ... -
Use of a single epiphyte lichen species Hypogymnia physodes as an indicator of air quality in northern Ontario
(1988)It has been determined that lichens are excellent indicators of regional air quality, since they are long-lived and totally dependent on atmospheric sources for nutrients. In the summer of 1987, samples of the ...
