Effects of Phylogenetic Tree Style on Student Comprehension
(North Dakota State University, 2017)
Phylogenetic trees are powerful tools of evolutionary biology that have become prominent across the life sciences. Consequently, learning to interpret and reason from phylogenetic trees is now an essential component of ...
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 ...
The Evolution and Development of a Novel Trait in Sepsidae
(North Dakota State University, 2016)
Evolutionary novelty, the appearance of new traits with no existing homology, is central to the adaptive radiation of new species. Novel traits inform our understanding of development and how developmental mechanisms can ...
Examination of Age at Death Methods and the Effects on Estimation Accuracy when Applied to Computed Tomography Scans and Virtual Models of Mummies
(North Dakota State University, 2015)
Three-dimensional (3D) medical imaging provides a method to non-invasively examine the sub-surface structures of a mummified body, particularly the skeleton. The unique nature of both natural and anthropogenic mummification ...
Evolution of the Growth Hormone Receptor: Insights Into the Molecular Basis of the Physiologically Pleiotropic Nature of the Growth Hormone Receptor
(North Dakota State University, 2014)
One of the oldest, extant, lineages of vertebrates, the sea lamprey, was used to clarify the evolutionary origin and divergence of the growth hormone receptor (GHR) family. A single, full-length, cDNA, and a second, partial, ...
