distribution of fishes in the thunder bay area of northwestern ontario since deglaciation, with special reference to the darters (genus etheostoma) and the sibley peninsula
(1991)the prevailing theory explaining fish distribution in the western lake superior basin states that recolonization was from south to north following the retreating ice margins. postulated access to post glacial lake superior ... -
height growth and site index of trembling aspen in north central ontario
(1991)height-growth and site-index curves were developed for estimating site quality of trembling aspen {populus tremuloides michx.) in north central ontario. these curves were developed from stem analysis data of dominant ... -
soil-site relations for jack pine (pinus banksiana lamb.) in northeastern ontario
(1994)site index of jack pine {pinus banksiana lamb) measured on 76 plots in northeastern ontario was related to features of soil and topography using multiple regression. site index at breast height age 50 years (sibhso) was ... -
height, growth and site index of jack pine (pinus banksiana lamb) in the thunder bay area : a system of site quality evaluation
(1986)height growth patterns and site index were studied using stem analyses taken from dominant and codominant trees growing on 109 plots located in mature, natural, fully stocked evenaged stands of jack pine {pinus banksiana ... -
soil-site relations for trembling aspen (populus tremuloides michx.) in northwestern ontario
(1991)soil-site relations for trembling aspen in northwestern ontario were studied using 98 site plots representing a wide range of glacial landforms, soil conditions, and site quality. site index was related to features of ... -
factors that predict brook trout distribution, thermal habitat, and abundance in northwestern ontario streams
(1995)predictive models were developed to improve the understanding of stream-resident brook trout (salvelinus fontinalis) populations and habitat in northwestern ontario, and to facilitate protection of stream-resident brook ... -
dynamics of a polyphagous lake trout, salvelinus namaycush (walbaum), population in a northwestern ontario lake
(1988)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 ... -
effects of selected biotic and abiotic factors on growth and survival of young crayfish, orconectes virilis (hagen)
(1988)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, ... -
population dynamics of an exploited population of orconectes virilis in northwestern ontario
(1987)exploitation of northern stocks of the crayfish orconectes virilis (hagen) produced significant alterations in several population parameters. high fishing efforts increased per capita fecundity, young-of-year (yoy) ... -
comparison of the yellow perch, perca flavescens mitchell, populations in henderson lake and savanne lake, ontario
(1984)yellow perch (perca flavescens) in henderson lake exhibit stunted growth and poor condition at all ages. in addition, they have lower fecundity, longer life span, slower maturation rate, and greater survival compared ... -
community dynamics resulting from an experimental pulse fishery on the walleye (stizostedion vitreum vitreum mitchill) in henderson lake
(1988)henderson lake is a small 151 ha boreal percid lake approximately 128km northwest of thunder bay. a pulse fishery conducted from 1980 to 1982 inclusively, removed 3226 walleye reducing the stock to very low levels (reid, ... -
the 96-hr lc50 and uptake of sodium tellurite in goldfish (carrasius auratus)
(1992)there is no information regarding toxicity of tellurium in fish. this research used goldfish (carassius auratus) as an animal model, and sodium tellurite ( na2te03) as the form of tellurium to tested. acute 96-hr lc50 ... -
detecting trends in walleye (stizostedion v. vitreum, mitchill) abundance using catch-effort data
(1995)three methods of analyzing catch-effort data were investigated regarding their relationship to walleye abundance: mean cue, gini coefficient and the relative frequency of zero cue (rfz). walleye recreational fishery ... -
ecology of a northern pike (esox iucius) population in a small, oligotrophic lake : with comparisons to other northwestern ontario populations
(1988)the life history and population dynamics of the northern pike (esox lucius) within squeers lake, ontario were studied in order to provide information on pike found within oligotrophic lakes. results clearly demonstrate ... -
effects of an episodic removal scheme on a walleye, stizostedion vitreum vitreum, population
(1985)a pulse fishing scheme, applied over a three year period (1980 to 1982), deliberately removed 3226 walleye from henderson lake, ontario, causing the stock to collapse. the objective of the removal was not only to seek ... -
ecology of forage fish following cessation of overharvest of walleye in henderson lake, ontario
(1988)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 ... -
impurity band conduction in reduced samples of bismuth iron molybdate
(1995)an experimental investigation of the electrical resistance of n-type bismuth iron molybdate (bi3femo2012) pellets at temperatures from 90 to 620 k has been made in an attempt to detect impurity band conduction near room ... -
photoluminescence and raman characterization of plee and mbe grown semiconductor epilayers
(1994)photoluminescence and raman investigations of selected alloy semiconductor epilayers are reported. correlations relating optical spectra and a number of intrinsic and extrinsic properties of the materials studied are ... -
development of nonlinear 3-d, and novel 2-d optical microscope imaging systems for time-lapse imaging
(2004)the design and development of a nonlinear two-photon, 3-d microscope imaging system, software for manipulation of 2-d and 3-d images, and the operation of a novel 2-d imaging system used for monitoring cultured live cell ... -
university that wasn't : the university of canada north, 1970-1985
(1994)the creation of the university of canada north, by federal letters patent in 1971, marks the beginning of a revealing episode in northern canadian history that spans almost fifteen years. the brain-child of toronto lawyer ...
