Direct and indirect effects of post-fire conditions on successional pathways and ecological processes in black spruce-Kalmia forests
(2002)The goal of this thesis was to estimate the relative importance of the mechanisms by which forest stands of east-central Newfoundland are replaced by unproductive dwarf-shrub communities following wildfire. Sheep laurel ... -
Distribution of Angiostrongylus vasorum and Crenosoma vulpis in red foxes (Vulpes vulpes) in Newfoundland, Canada

Habitat use, movement patterns, and home ranges of coaster brook trout in Nipigon Bay, Lake Superior
(2004)Coaster brook trout are one of two salmonine species native to Lake Superior. Abundant and widely distributed in Lake Superior a century ago, they have been reduced to a few remnant stocks due to exploitation and habitat ... -
Impacts of timber harvesting on stream macroinvertebrate communities at different spatial scales in Ontario's boreal forest
(2001)Study area: Wolf River, Mackenzie River, Spruce River and Nipigon 10 burn zone watersheds. These are tributaries of Lake Superior and lie within the northwestern Ontario boreal forest near Thunder Bay, Ontario. Sites were ... -
Influence of culverts on small stream fish communities in Northwestern Ontario / by Eric K. Berglund.
(2007)Stream crossings may alter fish habitat and fragment lotic environments, which could alter fish movement in stream reaches and lead to changes in fish community structure and population dynamics at the local and riverscape ... -
Influence of light intensity on activity and habitat utilization of walleye (Sander vitreus) in two Northwestern Ontario lakes
(2006)Ecologists have paid considerable attention to how and why organisms select particular habitats. Of fundamental importance is discerning which physical factors of the environment restrict the occurrence of organisms to ... -
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 ... -
Nesting ecology of a population of red-necked grebes in Northwestern Ontario
(2001)One of the largest, documented breeding populations of Red-necked Grebes (Podiceps grisegena holboelli) in the world was studied at Whitefish Lake, Ontario in 1993 and 1994. Whitefish Lake (WFL) represents a unique area ...
