Behavioral bioassay examining the effects of ethanol on flagfish reproduction
(1983)A behavioral bioassay method was developed to examine the effects of ethanol on the reproductive success and behavior of flagfish (Jordanella floridae). Reproductive behavior was divided into eight categories; egg ... -
Behaviour and reproductive success of female-female pairs of Ring-billed gulls (Larus delawarenis), Granite Island
(1982)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%) ... -
Biodegradation of fenitrothion and fenitrooxon by the soil fungus Trichoderma viride
(1987)The biodegradation of fenitrothion (0,0-dimethyl-0-(3-methyl-4-nitrophenyl)- phosphorothioate and fenitrooxon (0,0-dimethyl-0-(3-methyl-4-nitrophenyl)phosphate by the soil fungus Trichoderma viride Pers. has been ... -
Bioenergetic evaluation of a whole-lake nanosilver addition on Yellow Perch (Perca flavescens)
(2018)Nanosilver (nAg) is an antibacterial and antimicrobial agent. Its wide use in hundreds of commercial products and industrial applications suggests a high potential for release into the environment. Previous research indicates ... -
Biofilm formation of environmental and enterohemorrhagic Escherichia coli / by Stefan Moreira.

Biogenic lead levels in human skeletal remains from the cemetery of the British Royal Navy hospital (1793-1822CE) at English Harbour, Antigua West Indies
(2015)Though lead has been known to be a cause of human poisoning since ancient times, it was a widely used metal. The relationship between ancestry or age and lead exposure in the Colonial period of Antigua, West Indies was ... -
Biological activities of select North American lichens
(2017)The search for novel, pharmacologically significant compounds is a perpetual quest on which biologists, chemists, and bioinformaticians incessantly embark. The sources of these compounds are often of natural origin, making ... -
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 ... -
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 ... -
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 ... -
Biology of rumen flukes (Trematoda: Paramphistomatidae) in moose, Alces alces L., in northwestern Ontario
(1985)Paramphistoines {Parampbistomum sp.) were found in 86% of 160 moose rumens collected from northwestern Ontario at all seasons of the year. All moose older than 2.4 years were infected. The number of flukes per moose ranged ... -
Biology of the gastro-intestinal helminths of woodland and barren-ground caribou (Rangifer tarandus)
(1987)Twenty-one species of helminths were recovered from wild and captive caribou (Rangifer tarandus). Woodland caribou of the Slate Islands, barren-ground caribou of the Beverly herd and captive woodland caribou were parasitized ... -
Biosynthesis of ω–hydroxy fatty acid polyesters in Nicotiana tabacum stigmas
(2023)The aerial surfaces of all land plants are covered by hydrophobic lipid barriers that contain a core structure of polyesters derived from hydroxy fatty acids and glycerol. One type of surface lipid polyester is found in ... -
Black Spruce (Picea mariana) Regeneration in Post-fire Cryptogamic Mats
(2016)Post-fire black spruce (Picea mariana Mill.) regeneration has received considerable attention in management of the boreal forest of eastern Canada. Seedbed quality is a key factor for seed germination and early seedling ... -
