Influence of local and landscape scale factors on the presence, relative abundance and characteristics of brook trout (Salvelinus fontinalis) in beaver ponds
(2006)
Study area : Mackenzie River watershed, northeast of Thunder Bay, Northwestern Ontario (drains into Lake Superior)
The Influence of wetlands and watershed geology on lake chemistry of five remote lakes in Northwestern Ontario
(2012-11-10)
In chapter 1 of this study the relationship between spatial, chemical, and
biological factors and their influence on mercury concentration s in walleye were
examined. Water, sediment, and fish tissue samples were collected ...
Population genetics and phylogeography of aplodinotus grunniens (freshwater drum)
(2013-02-03)
The purpose of this study is to determine the population genetic and phylogeographic structure of Aplodinotus grunniens (freshwater drum) populations through analysis of the NADH dehydrogenase subunit 2 (ND2) region and ...
Is patch use determined by fine-scale microhabitat differences or density dependent habitat selection?
(2006)
If individuals base their patch and habitat choices on fine-scale differences in
microhabitat, then their use o f patches, defined by capture sites, should correspond with
measures o f microhabitat. But if individuals ...
Floristic structure, composition and depth of edge influence at buffer and wildfire edges along small boreal streams
(2009)
Within the boreal forest of northwestern Ontario clearcutting and fire are the most common edge-creating disturbances. Along streams, wild fire consumes the majority of trees to the edge of riparian zones. However, forest ...
Development of a toxicity early warning system (TEW)
(2006)
Biomonitoring is a practice that has over time developed into a remarkably
accurate form of detecting toxicity in the environment. The Toxicity Early Warning
system (TEW) is a Real-Time Biomonitoring system developed to ...
The Potential use of SIFT-MS as a breath diagnostic tool
(2009)
The measurement of volatile chemicals in human breath has recently emerged as a non-invasive technique with the potential for the early diagnosis of disease. A benefit of early diagnosis is that treatment plans including ...
Understory species response to partial harvesting in boreal riparian buffers
(2009)
In order to preserve valuable riparian functioning, forest harvesting in Canada attempts to protect riparian areas through the application of a no-harvest buffer zone around water bodies, and more recently through the ...
One-step inactivation of rpoS to investigate its role on Escherichia coli O157:H7 biofilm formation and survival
(2009)
Homologous linear recombination using the recombinogenic capabilites of phage red genes exo, bet and gam, has been used increasingly to generate targeted gene replacements in Gram-negative bacteria.
Detection and characterization of DNA damage
(2009)
The DNA molecule is constantly subjected to endogenous and exogenous sources of damage which if left unrepaired can lead to genotoxic and cytotoxic outcomes. These lesions have been implicated in the development of numerous ...
