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 ...
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 ...
The Effectiveness of environmental communication with scuba divers : a case study comparing the curricula of BSAC, PADI, and SSI entry-level certification courses
(2012-11-10)
The purpose of this study was to determine the effectiveness of the
environmental communications contained in novice certification course manuals. This
was accomplished by reviewing the effectiveness of these communications ...
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 ...
Wildfire dynamics of mixedwood boreal forests in central Canada
(2009)
Natural disturbances play a key role to forest regeneration, nutrient cycling, wildlife habitat, biodiversity, and climate regulation. A synthesis of literature indicated that boreal forest stand structure is largely a ...
Synthesis and modification of TiO2 and WO3 based nanostructured materials for environmental applications
(2015-10-21)
TiO2 and WO3 based nanomaterials are highly attractive for various applications encompassing photocatalysis, electrochromic devices, dye sensitized solar cells, hydrogen production, and sensing applications due to their ...
Ecophysiological responses of white birch seedlings to soil temperature and phosphorus supply under current and doubled carbon dioxide concentration
(2009)
To investigate the responses of some physiological and morphological traits to different soil temperature and phosphorus supply under current and doubled carbon dioxide concentration ([CO2]), white birch (Betula papyrifera ...
Carbon dynamics of boreal mixedwoods in central Canada
(2009)
Large amount of carbon (C) stored in boreal forest ecosystems plays an important role in the global carbon cycle. Forest ecosystem C is stored in four major pools: live vegetation (above-and below ground), dead woody ...
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 ...
Management, environmental and energy considerations for woodwaste
(2009)
Manufacturing operations that process raw wood, such as sawmills and pulp and paper mills, generate wood residue, such as woodwaste, sawdust, shavings, wood chips and off-cuts, also known as woodwaste. The decomposition ...
