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 ...
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 ...
Nesting Cavity Temperature Impacts Nesting Choice and Development of the Alfalfa Leafcutting Bee (Megachile rotundata)
(North Dakota State University, 2019)
Megachile rotundata is an agriculturally important pollinator of alfalfa and is not doing well in the U.S due to a 50% return rate (Pitts-Singer and Bosch, 2011). Nesting boxes can reach temperatures between 35˚C-48˚C (see ...
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 ...
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 ...
