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, ...
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 ...
The Effectiveness of 9, 10 Anthraquinone as a Repellent to Protect Oilseed Sunflower from Blackbird Depredation
(North Dakota State University, 2014)
Across the Prairie Pothole Region of North America, blackbirds (Icteridae) cause millions of dollars in damage to sunflower crops annually, but effective methods to prevent or limit blackbird damage to sunflower crops are ...
Diet and Effects of Environmental Stressors on the Altricial Nestlings of Double-Crested Cormorants (Phalacrocorax Auritus)
(North Dakota State University, 2014)
Double-crested cormorants (Phalacrocorax auritus) are a common species of altricial waterbird found across much of North America. As a piscivorous colonial waterbird, cormorants are often persecuted due to perceived impacts ...
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 ...
The Evaluation of Christmas Bird Counts as an Indicator of Population Trends and Habitat Selection in Blackbirds and Starlings
(North Dakota State University, 2011)
Agelaius phoeniceus (red-winged blackbird), Quiscalus quiscula (common
grackle), and Sturnus vulgaris (European starling) are three of the most abundant bird
species found in North America, and along with Euphagus carolinus ...
Development of the Stress Response in Fast (Coturnix Japonica) Versus Slow (Callipepla Gambelii) Growing Species
(North Dakota State University, 2012)
In this study, we evaluated the development of stress response in (1) two different species of quail, one species that is relatively fast-growing (Japanese quail, Coturnix japonica) and one that is relatively slow-growing ...
Drawing on Student Knowledge in Human Anatomy and Physiology
(North Dakota State University, 2014)
Prior to instruction, students may have developed alternative conceptions about the mechanics behind human physiology. To help students re-shape these ideas into correct reasoning, the faulty characteristics reinforcing ...
