Adaptive habitat selection by a single celled alga?
(2014-01-22)
Faculty and students in the Department of Biology are bound together by a common interest in explaining the diversity of life, the fit between form and function, and the distribution and abundance of organisms. The research ...
The antioxidant resveratrol down-regulates inflammation in an in vitro model of Pseudomonas aeruginosa infection of lung epithelial cells
(2014-01-22)
Pseudomonas aeruginosa is a Gram-negative opportunistic pathogen capable of infecting the lungs and causing severe pulmonary disease in immunocompromised individuals. During the infectious process, P. aeruginosa provokes ...
Lowbush blueberries in Northwestern Ontario as a commercial crop option in post-harvest peatlands
(2009-10-15)
Wild blueberries (Vaccinium angustifolium Ait.) were investigated as a possible reclamation tool for post harvest peatlands in Northwestern Ontario, by genetic fingerprinting using microsatellite markers, an examination ...
Role of safe sites in black spruce recruitment and growth release in post-fire Kalmia heath
(2014-01-22)
The goal of this thesis was to explain black spruce regeneration in postfire sheep laurel (Kalmia angustifolia L., hereafter referred to as Kalmia) dominated chronosequence in light of safe site density. The concept of ...
Testing British Columbia's water quality guidelines as a mixture of four important contaminants, hardness, exposure time, and species effects
(2014-12-19)
Provincial water quality guidelines are established in order to prevent detrimental effects
of a single toxicant from affecting the health of resident aquatic life. However, the
elevation of pollutants in freshwater can ...
The association between watershed characteristics and mercury concentrations in fish of Northern Ontario lakes
(2014-01-22)
Many landscape, limnological, and ecological factors synergistically affect the mercury cycle and subsequently influence total mercury (THg) concentrations in fish. In Chapter 1, the associations between watershed and lake ...
The Impacts of forest management practices on mercury contamination in small stream biota
(2012-11-10)
Mercury is a contaminant of global concern as it is present in all biota and ecosystems around the world. Small streams are influenced by the terrestrial systems that feed them. I examined the presence of mercury in small ...
Northern wild rice (Zizania palustris L.) as a phytoremediation species in eutrophic wetlands - investigation of root-sediment interactions
(2014-01-22)
The causes of anthropogenic eutrophication in water bodies are multi-faceted and multigenerational, presenting an ever increasing need for effective and sustainable solutions.Phytoremediation presents a cost-effective ...
The parasite communities of two populations of walleye (Sander vitreus) from Black Bay and Circle Lake, Ontario, Canada
(2017)
The parasite communities of fishes can provide important information on certain aspects of host biology such as where they have been, what they are eating, and what’s eating them. Unfortunately, fish parasite studies in ...
The effect of polyphenols on the angiotensin II receptor type 1 activation
(2017)
Hypertension, an increase in blood pressure, can lead to many serious complications, one of which is heart failure. Angiotensin (Ang) II is associated with hypertension; specifically, the Ang II receptor type 1 (AGTR1) is ...
