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 ...
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 ...
Relationship of body size to time of nesting and mate preference in the Ring-billed Gull (Larus delawarensis)
(1988)
The first part of this thesis investigated the relationship between time
of nesting and body size in Ring-billed Gulls (Larus delawarensis). There
were no significant differences in skeletal measurements among birds ...
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 ...
Patterns of allozyme variation in tamarack (Larix laricina (Du Roi) K. Koch) from northern Ontario
(1988)
Roots from approximately 30 trees from each of 44 populations across the range of tamarack (Larix laricina (Du Roi) K. Koch) in northern Ontario were analyzed electrophoretically for allozymic variation in 14 enzyme
systems ...
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, ...
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 ...
Mating behaviour, spermatophore structure, ecology and systematics of the Cicindela splendida group (Coleoptera: Cicindelidae)
(1988)
Observations of copulating pairs of conspecific and
interspecific individuals of Cicindela splendida Hentz and
Cicindela limbalis Klug revealed behaviour similar to that
previously described for Pseudoxych.ila tarsalis ...
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 ...
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, ...
