Postmating, Prezygotic Isolation among species of the Drosophila virilis subgroup
(University of Winnipeg, 2010-12-01)
Reproductive barriers between sexually reproducing organisms prevent interbreeding and
gene flow between species. Early studies of reproductive isolation focused on prezygotic and
postzygotic isolating mechanisms, yet ...
Reproductive and Genetic Consequences of Fragmentation in Chokecherry (Prunus virginiana, L.)
(University of Winnipeg, 2011-05-04)
Habitat fragmentation has the potential to negatively affect plant populations by disrupting gene flow, reducing genetic diversity and changing mating dynamics. However, the effect of fragmentation has been poorly investigated ...
Breeding Ecology of Wild and Captive-released Burrowing Owls (Athene cunicularia) in Southwestern Manitoba
(University of Winnipeg, 2016)
Burrowing Owls (Athene cunicularia) once occupied grassland ecosystems in the western Provinces of Canada, as far east as Winnipeg, Manitoba, and west into the southern interior of British Columbia (B.C.). No single factor ...
Identification of Renin Inhibiting Natural Products from Nauclea latifolia
(University of Winnipeg, 2011-08-30)
Natural products, particularly plants have been an important source of food and medicine throughout the history of mankind. High blood pressure has become a growing health burden all over the world. There is an obvious ...
Legendre Moments Explorations via Image Reconstruction
(University of Winnipeg, 2016-06-29)
Legendre Moment has been applied in image reconstruction since early years. In this research, a numerical integration method is proposed to improve the computational accuracy of Legendre moments. To clarify the improved ...
The effects of Livestock Grazing on Vegetation and Lepidopterans in Endangered Alvar Sites in Manitoba's Interlake: A thesis submitted to the Faculty of Graduate Studies in partial fulfillment of the requirements for the Masters of Science degree
(University of Winnipeg, 2018-07)
Alvar is a rare type of ecosystem characterized by open, flat terrain and incomplete vegetation intermixed with patches of exposed calcareous pavement. Alvars in Manitoba’s Interlake support tall grass prairie and boreal ...
Renewed Spirit in Winnipeg's North End: An emerging Aboriginal young adult co-creative leadership model
(University of Winnipeg, 2014-09-02)
This thesis argues that the Winnipeg youth movement, “Meet Me at the Bell Tower” (MMBT), offers a new form of spiritual, cultural, and political renewal. Qualitative data drawn from interviews of youth leaders in this ...
Millennial fire history reconstruction in the boreal forest of south-central Canada using lake-sediment charcoal, tree-ring and archival records
(University of Winnipeg, 2016)
The Canadian boreal forest has been developing since the end of the last glaciation approximately 10,000 years ago. During this time, fire has modified the development of the forest by altering species distribution, stand ...
Exploring Drumming/Song and its Relationship to Healing in the Lives of Indigenous Women Living in the City of Winnipeg
(The University of Winnipeg, 2014-12)
This is an exploratory study on drumming/song and its relationship to healing in the lives of Indigenous women living in the City of Winnipeg. The participants of this study included urban-based Indigenous women actively ...
A Comparative Study of Ryanodine Receptors (RyRs) Gene Expression Levels in the Basal Ray-Finned Fish, Bichir (Polypterus ornatipinnis) and the Derived Euteleost Zebrafish (Danio rerio)
(University of Winnipeg, 2010-09)
Ryanodine receptors (RyR) mediate the controlled release of intracellular stores of calcium from the sarcoplasmic reticulum. This release of calcium, triggered by membrane-depolarization, is responsible for initiating ...
