The effect of block composition on the severity of spruce beetle (Dendroctonus rufipennis) damage in northern British Columbia
(2021)The spruce beetle (Dendroctonus rufipennis) is a natural part of the western North American landscape, feeding on the phloem of trees in the Picea genus. The spruce beetle generally feeds on downed trees but can also ... -
Effect of blocked and random practice schedule variations on acquisition and retention of a pattern drawing task
(1998)The contextual interference (CI) effect refers to the phenomenon that practice organised according to a random schedule appears to negatively affect acquisition, while retention performance is facilitated. Previous ... -
Effect of body condition on reproductive performance and secondary sex ratios in ring-billed gulls (Larus delawarensis)
(1986)Nesting Ring-billed Gulls (Larus delawarensis) were studied on Granite Island, northern Lake Superior, during the breeding seasons of 1983 and 1984 to determine if there was a relationship between food supply and the ... -
Effect of boreal forest disturbance due to logging at different spatial scales on migratory songbirds
(2024)Boreal birds have experienced population declines that may be related to alteration of the forest at a range of scales. Understanding how resource extraction may affect the distribution and abundance of species is critical ... -
The Effect of breastfeeding on the neonatal abstinence scores of infants born to mothers on a methadone maintenance program : an epidemiological study
(2010)The objective of this research study is to determine the effects that breastfeeding has on methadone exposed infants with Neonatal Abstinence Syndrome (NAS), born at Thunder Bay Regional Health Sciences Centre. Methadone ... -
Effect of carbon-starvation on the survival of and PNP degradation by a Moraxella strain
(2004)The effect of carbon-starvation on the stress resistance responses of a p-nitrophenol degrading Moraxella strain was examined in both, buffer and river water samples. The Moraxella strain showed optimal stress resistance ... -
Effect of carbonation on leachability and compressive strength of cement-solidified and geopolymer-solidified synthetic metal wastes
(2012-11-10)Stabilization/solidification (s/s) is a well-established technique for treating a variety of metal-containing hazardous waste streams prior to land disposal. Solidification refers to the improvement of the physical ... -
Effect of chromium supplementation on blood glucose control in individuals with type 2 diabetes
(2003)The purpose of this study was to determine the effect of chromium supplementation on the blood glucose control of individuals with type 2 diabetes. A positive finding would result in substantial health and financial ... -
The effect of climate change on mountain pine beetle (Dendroctonus ponderosae Hopkins) in Western Canada
(2021)The mountain pine beetle, Dendroctonus ponderosae, (MPB) is the largest forest disturbance factor throughout its range in North America. The most recent MPB outbreak began in the 1990s and has resulted in an approximate ... -
The effect of cottage development on aquatic macroinvertebrate communities and water quality in central Ontario lakes
(2023)In Canada, over 3 million freshwater lakes provide a wide range of ecological, financial, aesthetic, and public health services for their citizens, communities, and tourists. This is especially true for regions like ... -
The effect of cycling female estradiol levels on retinal-based smooth pursuit eye movements (SPEM) and post-target offset persistence
(2015-06-15)Estradiol has primarily been associated with the female reproductive system; however, estradiol receptors have been located in the retinas of male and female humans, as well as throughout the central nervous system (CNS) ... -
The effect of ectomycorrhizal fungus Hebeloma longicaudum on drought stress of Pinus banksiana seedlings
(2023)This study looks at the influence of the ectomycorrhizal fungus Hebeloma longicaudum to form associations and impact growth of jack pine seedlings under simulated drought conditions. Four treatment groups of jack pine ... -
The effect of facial protection, impact location, and neckform stiffness on peak linear acceleration, risk of injury, and energy loading measures of horizontal impacts on a hockey helmet
(2018)Helmets were originally designed and implemented to protect players from skull fractures and traumatic brain injuries by minimizing linear impact accelerations. The sport of hockey, however, has evolved, and now includes ... -
Effect of feedback and motivational orientations on intrinsic motivations
(1998)The purpose of the study was to investigate how dispositional motivational orientations effect the perception of external rewards and the resulting effect on intrinsic motivation. Intrinsic motivation was assessed with ... -
