Does fire severity difference create divergent plant communities in black spruce-Kalmia forests of eastern Canada?
After fire, some conifer-ericaceous plant communities in Western Europe and eastern North America have demonstrated divergent succession from traditional conifer stand replacement to Ericaceae-dominated community states. ...
Sources of small-scale variation in headwater stream habitat and macroinvertebrate communities
The extent to which small stream habitats and communities are influenced by the surrounding terrestrial environment is a function of the linkage between aquatic and terrestrial systems. The strength of that linkage is ...
Lowbush blueberries in Northwestern Ontario as a commercial crop option in post-harvest peatlands
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 ...
Selected ion flow tube-mass spectrometry in plant volatile compound analysis
Four monoterpenes and two monoterpenoids, (+)- and DL-limonene, (1S)-(3) carene, terpinolene, cineol and rose oxide, respectively, were studied using selected ion flow tube-mass spectrometry. Specifically, the reactions ...
Floristic structure, composition and depth of edge influence at buffer and wildfire edges along small boreal streams
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 ...
The Potential use of SIFT-MS as a breath diagnostic tool
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
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
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
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 ...
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 ...
