Influence of Adjacent Uplands and Groundwater on the Hydrology and Invertebrate Community Composition of Seasonal Forest Ponds in North Central Minnesota
(North Dakota State University, 2010)Seasonal ponds are common throughout northern Minnesota's forested areas. Seasonal ponds typically flood due to snow-melt and high precipitation rates in early spring, then dry by mid-late summer. The dynamic hydroperiods ... -
The Influence of Body Size on Metabolic Rates, Scaling, Telomere Dynamics, and Metamorphosis in Megachilid Bees
(North Dakota State University, 2021)Body size is related to many aspects of a bee’s life history including foraging distance and pollination efficiency. Megachile rotundata, and Osmia lignaria are agriculturally important, solitary pollinators. Adult body ... -
Influence of Habitat Characteristics on Amphibian Stress and Reproductive Success in North Dakota
(North Dakota State University, 2021)As amphibians continue to decline, conservation efforts are a necessity in management plans. It is essential to determine the correlation between water characteristics, stress, and habitat alteration with anuran losses. ... -
Interaction and Innovation: The Impacts of Social Factors and Classroom Type on University Biology Instructor Classroom Assessment Decisions
(North Dakota State University, 2020)Efforts to improve university science education continue to emphasize the importance of active learning, including frequent formative assessment and timely feedback that helps students reach desired learning outcomes. Yet, ... -
An Investigation of Student Understanding and Acceptance of Evolution
(North Dakota State University, 2021)Evolution is central to biology education and yet, it is often one of the most misunderstood and controversial topics that biology educators must teach. Research spanning the last four decades has shown that students ... -
Investigation of the Nature of Science Views of Undergraduate Natural Science and Nonscience Majors in Biology Courses
(North Dakota State University, 2010)Science educators have the common goal of helping students develop scientific literacy, including understanding of the nature of science (NOS). University faculties are challenged with the need to develop informed NOS ... -
Long-Term Monitoring of Bat Populations in North Dakota
(North Dakota State University, 2022)Throughout the past few decades, North American bat species have experienced population declines due to White-Nose Syndrome, wind energy, climate change, and other factors. In North Dakota, the presence of wind energy, and ... -
Low Temperature Stress in the Alfalfa Leafcutting Bee, Megachile Rotundata
(North Dakota State University, 2017)Dramatic changes in ambient temperature can have a significant impact on insect physiology throughout development. The accumulations of the deleterious physiological effects throughout low temperature exposure are collectively ... -
Matrix Metalloproteinase Expression Varies Throughout Development and During the Innate Immune Response of Tobacco Hornworm. Manduca sexta
(North Dakota State University, 2010)Matrix metalloproteinases (MI'v1Ps) are a family of conserved, proteolytic enzymes. MMPs can degrade most extracellular matrix proteins. As such, they are key enzymes in tissue remodeling processes. such as molting and ... -
Nesting Cavity Temperature Impacts Nesting Choice and Development of the Alfalfa Leafcutting Bee (Megachile rotundata)
(North Dakota State University, 2019)Megachile rotundata is an agriculturally important pollinator of alfalfa and is not doing well in the U.S due to a 50% return rate (Pitts-Singer and Bosch, 2011). Nesting boxes can reach temperatures between 35˚C-48˚C (see ... -
‘Omics’ approaches to understand ecology and physiology of bees
(North Dakota State University, 2024)Bees face several ecological and physiological challenges due to poor nutrition and abiotic stress. This dissertation explores various aspects related to these challenges, including the microbial ecology of honey bees and ... -
On the Origin of Modern Horse Breeds from Four Distinct Subspecies of Equus Caballus
(North Dakota State University, 2016)Although the evolution and domestication of the horse has been extensively studied, many mysteries remain. No other animal has been as influential on the development of human societies and cultures as the horse. Horses ... -
Online Student Resource Use and the Effect on Student Course Performance
(North Dakota State University, 2013)The purpose of this study was to identify potential factors of student resource use that could indicate student success in an online course. This would allow instructors to look for in patterns of use to identify students ... -
Peripheral Hormone Interactions with the Growth Hormone-Insulin-Like Growth Factor (GH-IGF) System in Rainbow Trout
(North Dakota State University, 2019)The growth of vertebrates is primarily regulated by the growth hormone-insulin-like growth factor (GH-IGF) system, but not in isolation. The central question of this dissertation was how do other hormones peripheral to the ... -
Personality and Behavioral Syndromes of the Big Brown Bat, Eptesicus fuscus
(North Dakota State University, 2018)As the study of animal personality has significant expanded in the last decade, a growing amount of research has focused on the impacts of sociality and group dynamics on behavioral repeatability. The research presented ... -
Physiological Mechanisms Underpinning Growth and Aging in Wild Birds
(North Dakota State University, 2019)Life-history trade-offs have been well-documented within the literature through correlational and experimental studies. However, the physiological mechanisms underlying these trade-offs are less understood. Currently, there ... -
Plant Phenological Responses to Climate Change in the Northern Great Plains
(North Dakota State University, 2010)Climate change has been associated with shifts in phenological events which could be disrupting evolved species relationships. The current first flowering times of plants were compared to historical data in the Red River ... -
