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 ... -
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 ... -
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 ... -
Environmental Factors Influencing Tumor Associated Pericyte Phenotype in Pancreatic Cancer
(North Dakota State University, 2021)Pancreatic ductal adenocarcinoma (PDAC) is the third leading cause of cancer death in the U.S. with a 5-year survival rate of 11%. PDAC patients suffer from the lack of effective treatment options largely due to the limited ... -
Effects of Processing on Health-Promoting Attributes of Soymilk Phenolics
(North Dakota State University, 2010)This study was designed to investigate the effects of different processing methods on the antioxidant and anti-cancer properties of soymilk crude phenolic extract (CPE) using the human prostate cancer cell line DU 145 ... -
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 ... -
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. ... -
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 ... -
Energetics of Interrupted Development in Megachile rotundata
(North Dakota State University, 2022)Insects in temperate regions may experience temperature fluctuations during springtime development which can lead to low temperature stress. Previous research has shown that short artificial fluctuations in temperature ... -
The Effects of Variation in Temperature and Parental Behavior on Offspring Body Mass, Telomeres and Survival Are Context-Dependent in Free Living House Sparrows (Passer domesticus)
(North Dakota State University, 2022)Although developing birds are vulnerable to extreme and erratic temperature conditions associated with climate change, parents have some ability to buffer these effects via incubation and postnatal behavior. However, parents ... -
Establishing and Characterizing Patient-Derived Breast Cancer Cell Lines
(North Dakota State University, 2022)Commercial cancer cell lines have long been extensively used as an important platform to study cancer. They have contributed to a plethora of discoveries in the field of cancer research. However, there are limitations with ... -
Assessment of Blackbird Damage to Sunflower and Corn Fields in the Prairie Pothole Region of North Dakota
(North Dakota State University, 2011)North Dakota is the top sunflower producing state in the United States, annually harvesting about 405,000 ha (1 million acres). Up to 63% of this crop is grown in central North Dakota in an area known as the Prairie Pothole ... -
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. ... -
Foraging Strategies and Morphometric Characteristics of Bats in North and South Dakota
(North Dakota State University, 2021)Insectivorous bats are an important group for studying links between dietary flexibility and associated impacts on foraging and morphology of individuals from different populations. Since different habitats generally have ... -
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. ... -
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 ... -
Faculty Intention and Faculty Implementation - Do They Align?
(North Dakota State University, 2021)There have been a multitude of calls to reform teaching in undergraduate education. The implementation of active learning in the classroom increases student learning, relative to traditional lecturing. I worked with ... -
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 ... -
Alignment of Genetic Variation, Plasticity, and Selection, and the Effects of Cost of Plasticity
(North Dakota State University, 2021)Phenotypic expression depends on both the underlying genetics and the environment the phenotype is expressed in, i.e., plasticity. Adaptive theory predicts that selection should align with the dimensions of most genetic ... -
An Evaluation of the Social Perceptions and Biological Efficacy of Unmanned Aircraft Systems for Avian-Agriculture Conflict
(North Dakota State University, 2021)North Dakota sunflower producers face a dilemma when it comes to blackbirds (Icteridae). Migrating flocks produce localized damage to production, which results in some farmers with no bird issues, while others face total ...
