Assessment of the Spatial and Temporal Hydroclimatic Variability of the Canadian Prairie Provinces
(Faculty of Graduate Studies and Research, University of Regina, 2020-09)Natural climatic variability, changing climatic conditions, periodic droughts, and excessive moisture events impact agriculture, industry, municipalities, and surface water resource management throughout the Canadian ... -
Common Nighthawk (Chordeiles minor) Habitat Associations and Activity Patterns in the Northern Boreal Forest
(Faculty of Graduate Studies and Research, University of Regina, 2017-11)Understanding how organisms interact with their environment is key to developing effective management strategies. Due to population declines detected in the southern part of their range, Common Nighthawks (Chordeiles minor) ... -
Dynamics of Forest-Grassland Boundaries in Cypress Hills Interprovincial Park
(Faculty of Graduate Studies and Research, University of Regina, 2021-09)My research evaluated the rate and nature of forest expansion within the Cypress Hills Interprovincial Park in western Canada, where it is currently a topic of management interest. I analyzed historical aerial photographs ... -
Habitat Use by Common Nighthawks (Chordeiles minor) in Canada's Boreal Forest
(Faculty of Graduate Studies and Research, University of Regina, 2018-10)Diurnal aerial insectivores, a guild of birds related by foraging behaviour, are declining rapidly across North America but the reasons for the decline are unknown. One of these guild members, the Common Nighthawk (Chordeiles ... -
Movement Patterns of Migratory Bats during Autumn Migration
(Faculty of Graduate Studies and Research, University of Regina, 2022-03-28)Migration routes of long-distance migratory tree-roosting bats (Lasiurus cinereus, L. borealis and Lasionycteris noctivagans) in North America are poorly understood. Large numbers of bat fatalities recorded at wind energy ... -
A Riparian Buffer at 10 Years: The Effect of Black Plastic Mulch on Soil Variables, Nutirent Stocks and Tree Biomass
(Faculty of Graduate Studies and Research, University of Regina, 2021-03)Riparian zones are the interface between terrestrial and aquatic ecosystems. Riparian buffers are an important component of this interface environment because the vegetation of the buffer can provide many ecosystem services. ... -
Rodent Responses to Land Modification for Agriculture: Implications for Trophic Dynamics In the Northern Great Plains
(Faculty of Graduate Studies and Research, University of Regina, 2019-03)My thesis examines rodent species responses to agricultural land modification and their implications for trophic dynamics on the northern Great Plains. I first validated owl pellet analysis as a landscape-level sampling ... -
Tall Timber: Roost Tree Selection of Reproductive Female Silver-Haired Bats (LASIONYCTERIS NOCTIVAGANS)
(Faculty of Graduate Studies and Research, University of Regina, 2017-08)Habitat loss is the most significant contributor to the extinction of species worldwide, and yet for many species, habitat requirements remain largely unknown. Identifying habitat is important, especially because the ... -
Understory Composition, Seedling Growth, and Snag Frequency Across a Water-Limited Forest Landscape
(Faculty of Graduate Studies and Research, University of Regina, 2020-10)Global change is expected to increase drought intensity and make precipitation more uncertain. These changes can affect forest plant communities directly by altering demographic rates, and indirectly through interspecific ... -
Variation in Tree Growth and Vascular Formation Across A Water-Limited Forest Landscape From 1951 to 2016
(Faculty of Graduate Studies and Research, University of Regina, 2019-01)Tree growth in sub-humid forests is influenced by environmental conditions that may differ across local topographic gradients. My study investigated how the growth of two conifer species (Pinus contorta var. latifolia ...
