Campylobacter jejuni : biofilm formation and oxidative stress
Campylobacter jejuni (C. jejuni) is a zoonotic pathogen most often associated with poultry and the leading cause of bacterial gastroenteritis in the developed world. It is an obligate microaerobe, requiring low levels of ...
Habitat use and movement by brook trout (Salvelinus fontinalis) and rainbow trout (Oncorhynchus mykiss) in three tributaries of Nipigon Bay, Lake Superior
Three streams were surveyed: Dublin Creek, MacInnes Creek, and Little Cypress River in Northwestern Ontario.
Characterization of the second internal transcribed spacer (ITS-2)rDNA region among the Elaphostrongylinae (Nematoda:Protostrongylidae)
Four species of elaphostrongyline nematodes are known to infect cervids in North America. One species, Parelaphostrongylus tenuis, can cause neurologic disease (parelaphostrongylosis) in cervid hosts other than white ...
Effectiveness of self-restoration for two small mine impacted shield lakes
Cleaver Lake and Horneblende Lake in the Whitesand Watershed were studied for the impact of mining and milling activities. No release of zinc, copper, iron, or manganese was detected in aerated sediment samples and there ...
Roadside floristic patterns and revegetation by using native plants in Terra Nova National Park, Newfoundland, Canada
This thesis reports on a study of roadside floristic patterns and revegetation (cultural methods) of newly constructed roadsides by using native plants along Trans Canada Highway (TCH) in Terra Nova National Park (TNNP), ...
Habitat use, movement patterns, and home ranges of coaster brook trout in Nipigon Bay, Lake Superior
Coaster brook trout are one of two salmonine species native to Lake Superior. Abundant and widely distributed in Lake Superior a century ago, they have been reduced to a few remnant stocks due to exploitation and habitat ...
Black spruce regeneration in Kalmia dominated sites : effects of mycorrhizal inoculation and forest floor mixing
Study area : Terra Nova National Park, 90 km southeast of Gander, Newfoundland.
Molecular detection and identification of parasites involved in human disease
The detection and identification of disease-causing parasites via DNA and the polymerase chain reaction (PCR) offers a new approach for quick and efficient disease diagnosis. Three nucleic acid based technologies have ...
Tissue culture system facilitates examination of gene expression during breakage of vegetative dormancy in the potato tuber shoot apical meristem
While the shoot apical meristem's role during dormancy emergence in seeds is relatively well-understood, molecular factors governing vegetative endodormancy and sprouting in tuberous plants have not been well studied. A ...
Impacts of timber harvesting on stream macroinvertebrate communities at different spatial scales in Ontario's boreal forest
Study area: Wolf River, Mackenzie River, Spruce River and Nipigon 10 burn zone watersheds. These are tributaries of Lake Superior and lie within the northwestern Ontario boreal forest near Thunder Bay, Ontario. Sites were ...
