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 ... -
Characteristics of connectivity between harvested landscapes and fixed-width riparian buffers
(2013-02-03)Fixed-width riparian buffers are a common best management policy enforced in forested landscapes on first and higher order streams. These buffer areas are delineated along stream banks in the field, based on the presence ... -
Characterization of rainbow trout (Oncorhynchus mykiss) and fathead minnow (Pimephales promelas) cell lines as models to study pulp and paper effluent effects in fish
(2012-11-10)The effects of aquatic toxicants on fish growth and development have been well-documented, in contrast to the changes in gene expression that necessarily precede them. Many of these toxicants are exogenous compounds that ... -
An investigation of saccharide complexation by aqueous oxoacids. Can oxoacids mediate A1-2 quorum sensing in bacteria?
(2013-02-12)The goal of this investigation was to determine whether it is plausible for bacterial AI-2 quorum sensing to be selectively regulated by environmentally available oxoacids. In particular, we investigated the ability of ... -
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 ...
