Effects of timber management practices on the use of aquatic feeding areas by moose (Alces alces) in the Great Lakes-St. Lawrence and boreal transition forests of Central Ontario
During spring and summer in Ontario, moose are commonly observed at sites known as moose aquatic feeding areas. Feeding on aquatic vegetation is thought to be an important source of sodium for moose at this time of year. ...
Genetic profiling variation caused by tissue type, error, and damage
Genetic profiling variations caused by tissue type, error, and damage have been studied only minimally in the past. Even though it is well accepted that damage to the DNA molecule and PCR induced error occur, little focus ...
Direct and indirect effects of post-fire conditions on successional pathways and ecological processes in black spruce-Kalmia forests
The goal of this thesis was to estimate the relative importance of the mechanisms by which forest stands of east-central Newfoundland are replaced by unproductive dwarf-shrub communities following wildfire. Sheep laurel ...
Study of host pathogen interactions using a model of Pseudomonas aeruginosa infection of lung epithelial cells / by Rebecca Barnes.
Pseudomonas aeruginosa is an opportunistic pulmonary pathogen that can cause acute, life-threatening pneumonia in immunocompromised individuals, it is a common cause of high-mortality ventilator associated pneumonia, and ...
Towards the optimisation of a detection system for markers linked to neural tube defects
Neural tube defects are the second most common birth defect of the central nervous system. The aim of this research is to design and optimise a novel detection system to analyse five markers that have been shown to be ...
Characterization of genetic determinants for growth and structure of Listeria monocytogenes biofilms / by Nicholas Choy.
This thesis investigated wild-type 'Listeria monocytogenes ' EGD and five of its corresponding mutant strains (M1, M4, M7, M11 and M14) for their ability to form biofilms on glass at 22°C and 37°C, with and without shear ...
Prediction of a modern gold mine's contaminant dispersion and deposition in a river mixing zone
Study site: Placer Dome Canada's Musselwhite Mine near Pickle Lake Ontario.
Use of wetlands to remediate gold mine effluent
The effluent from Musselwhite Mine was examined to determine the improvement to water quality as it passed through a treatment wetland prior to final discharge to the receiving water body. Potential toxicity problems ...
Nesting ecology of a population of red-necked grebes in Northwestern Ontario
One of the largest, documented breeding populations of Red-necked Grebes (Podiceps grisegena holboelli) in the world was studied at Whitefish Lake, Ontario in 1993 and 1994. Whitefish Lake (WFL) represents a unique area ...
The Decline of a Northern Lake Superior marsh : a study of the cause and effect
This study quantified the loss of vegetation in Mission Marsh located within the city limits of Thunder Bay on the northern shore of Lake Superior, suggested the most likely cause of this vegetation loss, and examined in ...
