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 ...

Nesting Ring-billed Gulls (Larus delawarensis) were studied on Granite Island, northern Lake Superior, during the breeding seasons of 1983 and 1984 to determine if there was a relationship between food supply and the ...

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 ...

Initial investigations into bioacoustics of Cicindela spp. (Cicindelidae: Coleoptera) were designed to establish the systematic usefulness of acoustic variables, the possibility of auditory communication, and lay ...

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, ...

Annual production of the amphipod Hyalella azteca was estimated in the upper littoral zone of Dock Lake, Ontario, over a 2 year period (1980-1981). Population density (negligible below 1 meter) differed among the three ...

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 ...

The subfamily Schistorophinae Travassos, 1918 is revised. Five species of Schistorophus Railliet, 1916 are recognized: (1) longicornis (Hemprich and Ehrenberg in Schneider, 1866) with S. indica (Sanwal, 1952) and ...

The effect of participation in a physical fitness programme of moderate intensity on plasma lipoprotein cholesterols, total cholesterol, triglycerides and apolipoprotein-A levels was investigated. Forty-nine inactive ...

Female-female pairs of Ring-billed Gulls were studied on Granite Island, northern Lake Superior, during the breeding seasons of 1979 and 1980. In 1979 the colony consisted of approximately 2400 pairs with 99 nests (4.1%) ...
