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 ...
The Conservation of Variation in Gryllodes sigillatus and Closely Related Cricket Species
(North Dakota State University, 2020)
The ability to adjust behaviors to a particular environment has been well documented across taxa. Our understanding of behavioral plasticity is largely based on experiments in which individuals have a single exposure to ...
Evolution of Intraspecific Genetic Differences Across Heterogeneous Environments and the Potential Impacts on Environmental Restoration
(North Dakota State University, 2020)
Genetic differences evolve between seed sources of widely distributed species that can impact restoration success. Using the herbaceous perennial Geum triflorum (Pursh) as a model species, we examine genetic differences ...
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 ...
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 ...
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 ...
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 ...
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. ...
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 ...
