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 ...
Dielectric and infrared studies of radio frequency processes in some alcohols
(1988)
In this thesis, the results of dielectric studies on a number of aliphatic
alcohol molecules with variable chain lengths are presented. This investigation was
complemented by infrared and viscosity measurements. Dielectric ...
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, ...
Reactions of Ni(II) with NaBh4 and NaBh3 CN in the presence of mono-and bidentate phosphines under CO atmosphere
(1988)
Phosphine-substituted carbonyl complexes of Ni have been prepared.
The reaction between NiC12.6H20, NaBH4 or NaBH3CN and either PPh3 or a series of phosphines of the type Ph2P-(CH2)n-PPh2 (n=1-5) and also cis-dppe under ...
Effect of prenatal cadmium exposure on development and behavior of selectively bred genetic lines of rat
(1988)
PELLETIER, M. R. (1988). Effect of prenatal cadmium
exposure on development and behavior of selectively
bred genetic lines of rat: The purpose of the study was
to investigate the effects of cadmium exposure as
related ...
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 ...
Morphological variation in subalpine fir and its relationship to balsam fir in western Canada and the United States
(1988)
To help clarify the taxonomy of the two closely related North American firs
subalpine fir {Abies lasiocarpa (Hook.) Nutt.) and balsam fir {Abies balsamea
(L.) Mill.) in western Canada and the United States, 10 populations ...
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 ...
Genetic variation in growth and yield components of juvenile balsam poplar (Populus balsamifera L.) growing in northwestern Ontario / by Frank Schnekenburger
(1988)
A nursery and greenhouse study of balsam poplar (Populus
balsamifera L.) were carried out in Thunder Bay, Ontario, to
study the extent and nature of variation in growth and its
relation to the following yield components: ...
