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 ...
Aging and Early Life Stress: Telomerase Dynamics and The Consequences for Telomeres in a Wild Bird
(North Dakota State University, 2020)
Aging is an underlying risk factor for many major diseases including cancer, cardiovascular disease, and neurodegeneration. Yet we still do not know the full extent of how our bodies age and what determines our lifespan. ...
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 ...
Evidence of Climate Niche Creation in the Northern Great Plains: The History of Invasion, Population Genetics, Competitive Effect, and Long-Term Trends of Invasive Poa Pratensis L.
(North Dakota State University, 2016)
Understanding the mechanisms of invasion is critical in order to control an invasive species. Poa pratensis L. (Kentucky bluegrass) is an invasive species that has been present in the northern Great Plains (NGP) for over ...
Developmental Effects on Immunity: Hormonal and Proteinase Control
(North Dakota State University, 2016)
Insects are ubiquitous, diverse, and able to combat infections despite their lack of adaptive immunity. Insects have a robust innate immune system that is divided into two branches, cell-mediated and humoral. Activation ...
Ecophysiological Implications of Spring Conditions on the Alfalfa Leafcutting Bee, Megachile rotundata
(North Dakota State University, 2017)
Spring conditions stimulate development of many plants and animals after a period of winter dormancy. Climate change is predicted to cause earlier spring thaws, increasing temperature variability, and more frequent cold ...
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 ...
Suites of Behavioral and Physiological Characteristics of Japanese Quail (Coturnix Japonica)
(North Dakota State University, 2015)
The concept of personalities is used as a way to understand suites of behaviors associated with how animals cope with change. Animal personalities can be described along a continuum from bold to shy and describe suites of ...
Telomere Correlations during Early Life in a Long Lived Seabird
(North Dakota State University, 2018)
Telomere dynamics in blood cells have been linked to aging in a variety of organisms. However, whether blood telomeres correlated with telomeres in other parts of the body is not well known, especially during early life ...
Growth and Development of Native Range Plants in the Mixed Grass Prairie of Western North Dakota
(North Dakota State University, 1963)
This study was initiated to secure quantitative data on growth characteristics of the major species in the mixed grass prairie of western North Dakota; to determine the extent and range in yearly variations in growth ...
