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 ... -
Population Dynamics and Management Implications for American White Pelicans (Pelecanus Erythrorhynchos) Breeding at Marsh Lake, Lac Qui Parle Wildlife Management Area, Minnesota
(North Dakota State University, 2016)The American white pelican (Pelecanus erythrorhynchos) is a prominent breeding bird in Minnesota, but little information has been available on their production, population dynamics, growth and development, or demographic ... -
The Prairie Science Classroom: Original Outcome Durability and Impact on the Connection to Nature
(North Dakota State University, 2017)Environmental Education (EE) seeks to create an informed citizenry capable of taking action on environmental issues. Recent calls for more consistent evaluation of EE point to a need for more long-term evaluations as well ... -
Quantifying Seasonal Variation in Physiological Condition of Adult Franklin's Gull (Luecophaeus Pipixcan) during Nesting
(North Dakota State University, 2011)Understanding seasonal variation in adult physiological condition is important for developing hypotheses on how nest initiation, adult condition, chick development and recruitment are related in Franklin's gull and other ... -
Red-Winged Blackbird Migration Distance and Its Relationship with Reproduction
(North Dakota State University, 2020)Red-winged blackbirds (Agelaius phoeniceus) are one of the most commonly researched birds in North America. My study aims to build upon what is known about migration patterns and reproduction in this species. My first ... -
Rural Youth's Enrollment in a Stem Summer Camp: A Comparison Between In-Person and Take-Home Experiences
(North Dakota State University, 2021)The utilization of informal STEM education opportunities has been well established as a way to supplement and support formal STEM education learning. Many of the studies confirming this were completed in urban settings. ... -
Short- and Long-Term Effects of Environmental Variability on the Ecophysiology of a Solitary Bee
(North Dakota State University, 2022)Environments can vary across seasons. One characteristic of spring in temperate regions is fluctuations in temperature. Sudden bouts of low temperature can have lasting effects on ectotherms that rely on ambient temperature. ... -
Social and Acoustic Behavior of the Leaf-Roosting Bat Thyroptera Tricolor
(North Dakota State University, 2015)The limited availability of refuges may represent an important factor promoting the evolution of sociality, particularly in bats. Spix’s disc-winged bats (Thyroptera tricolor) show highly specialized morphological adaptations ... -
Stereotype Threat in the Introductory Science Classroom: Investigating Its Existence and Triggers
(North Dakota State University, 2013)Research in undergraduate education has documented achievement gaps between men and women in math and physics that may reflect, in part, a response to perceived stereotype threat. My research efforts aimed to reduce ... -
Student Interpretations of Phylogenetic Trees in an Introductory Biology Course
(North Dakota State University, 2013)Phylogenetic trees are a common visual representation in biology, and the most important visual representation used in evolutionary biology. Thus, phylogenetic trees have also become an important component of biology ...
