Priming physiology and proteinase purification from resting jack pine seeds
(1989)
Pines constitute an important economic species for the lumber and paper
industries in the Boreal region (Galloway, 1986). Current seedling production,
dependent on the availability of high quality seed, may be considered ...
Germination in pea seeds : proteolytic enzyme activity and electron microscopy
(1989)
This study was undertaken with two primary objectives in mind. The first objective was to isolate several pea seed hydrolases present during early seed germination. The second objective was to perform an ultrastructural ...
Systematics and ecology of the Sexguttata species group, genus Cicindela (Coleoptera: Cicindelidae) / by Michael M. Kaulbars. --
(1982)
The systematics of Cicindela sexguttata Fabricius and
Cicindela patruela Dejean was studied. Various aspects of
their holomorphology were considered, including: multivariate
analysis of external characters, morphology ...
Studies on the fungus Flammulina velutipes
(1987)
Local ligninocellulosic waste materials were examined as substrates for growing Flammulina velutipes mushrooms. Mushroom production was favoured by substrate moisture content in the range of 125-150%, (substrate supplementation ...
Biology and histopathology of Proteocephalus ambloplitis Liedy, 1887, infecting walleye (Stizostedion vitreum vitreum) and yellow perch (Perea flavescens) in Lake of the Woods, Ontario
(1985)
Walleye (Stizostedion vitreum vitreum ) and yellow
perch (Perea flavescens ) from Lake of the Woods were
examined for parenteral Proteocephalus ambloplitis from
May to November, 1982 and 1983. One hundred percent of ...
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 ...
Biology of "peak" and "late" nesting Ring-billed gulls, Granite Island, Lake Superior
(1982)
Late-nesting Ring-billed Gulls in this study laid fewer
and smaller eggs and hatched fewer young than earlier nesting
pairs. Birds nesting late in the season appeared to lack
sufficient stimuli for incubation, as indicated ...
Attempts to differentiate elaphostrongyline larvae (Nematoda : Protostrongylidae) using guinea pigs (Cavia porcellus) as alternate hosts
(1989)
First-and third-stage larvae of Parelaphostrongylus tenuis, P. andersoni
and Elaphostrongylus cervi could not be distinguished morphometrically. Third-stage
larvae of P. tenuis did develop into recognizable adults ...
Migration and development of Cystidicola spp. (Habronematoidea) in their definitive hosts and the population biology of C. cristivomeri White, 1941 in Salvelinus spp.
(1980)
The development of Cystidicola cristivomeri in lake
trout, Salvelinus namaycush, and C, farionis in rainbow trout,
Salmo gairdneri, is described. The population biology of
C. cristivomeri was investigated in lake trout ...
Biology of Cystidicola farionis Fischer, 1798 (Nematoda : Cystidicolidae) in salmonid fishes
(1987)
Morphological studies, experimental cross-infections and host specificity data suggest that the species of swimbladder nematode which matures in Coregonus clupeaformis, from inland lakes is not distinct from Cystidicola ...
