Dyke rocks occurring in the Coldwell alkaline instrusive complex, N. W. Ontario, were studied by various petrographic and geochemical means. The resulting observations indicate that 5 types of mafic alkaline lamprophyres, ...

I examined the forage base of Henderson Lake, Ontario following collapse of its walleye stock due to overexploitation, and an inexplicable decline of the ninespine stickleback population. In response to these events a ...

Triaxial compression tests were preformed such that changes in the magnetic susceptibility anisotropy with strain would be represented by experimental approximations of simple shear and pure shear. Both types of tests ...

The objective of this thesis was to develop a spatially sound timber management strategy design tool. Long-range timber management modelling systems were identified as being limited by the inability to perform large-scale ...

The growth and survival of Orconectes virilis young was studied in 50 x 50 x 50 cm lake enclosures during the summer seasons of 1986 and 1987. The effects of density (12/m2, 40/m2, 160/m2), substrate (mud, sand, ...

The objective of this study was to develop an analytical technique to enable forest managers to handle effectively the complex problem of integrated resource management planning using quantitative and qualitative information. ...

Larix Iyallii Parl, (alpine larch) is a small to medium tree restricted to the timberline zone of the mountainous regions of the Pacific Northwest of the United States and the adjacent southwest of Canada. To examine ...

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 ...

Tagging studies, index gill netting and an experimental winter fishery were used to investigate the dynamics of a polyphagous lake trout (Salvelinus namaycush population in Squeers Lake of northwestern Ontario. The ...
