The Distribution and Habitat Use of North Dakota Bats
(North Dakota State University, 2014)Prior to 2009, a comprehensive statewide survey of occurrence and distribution of bats in North Dakota had not been conducted. From 2009 to 2012, mist netting, radio telemetry, and acoustic monitoring were conducted to ... -
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 ... -
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 ... -
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 ... -
From Alcelaphus to Zapus: Conservation of Modern Mammalian Populations
(North Dakota State University, 2015)Conservation priorities are increasingly important in the face of modern human activities. Anthropogenic activities such as deforestation, pollution, and climate change have negative impacts on all vertebrates. In chapter ... -
Characterizing the Immune Response of the Alfalfa Leafcutting Bee throughout Pupal Development
(North Dakota State University, 2015)Megachile rotundata is a solitary cavity nesting bee that is the primary commercial pollinator of alfalfa in North America. During prepupal to adult development, they may be exposed to fungal, parasitic, and bacterial ... -
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 ... -
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 ... -
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 ... -
Expression of HIF-1 Alpha and HIF-1 Beta in Insects Throughout Juvenile Development
(North Dakota State University, 2016)Insects grow exponentially from hatching to adult. This growth is punctuated by periodic molts during which the exoskeleton, including the large airways of the respiratory system, is enlarged and replaced. Major tracheae ... -
Population Dynamics and Management Implications for American White Pelicans (Pelecanus Erythrorhynchos) Breeding at Marsh Lake, Lac Qui Parle Wildlife Management Area, Minnesota
(North Dakota State University, 2016)The American white pelican (Pelecanus erythrorhynchos) is a prominent breeding bird in Minnesota, but little information has been available on their production, population dynamics, growth and development, or demographic ... -
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 ... -
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 ... -
Surfing the Semester: A Study of the Flow of Active Learning Implementation
(North Dakota State University, 2017)Instructional reforms have been called for on a national level. Little data exists as to how changes take place. This study explored the implementation of active learning practices by non-tenure and tenure track faculty ... -
Low Temperature Stress in the Alfalfa Leafcutting Bee, Megachile Rotundata
(North Dakota State University, 2017)Dramatic changes in ambient temperature can have a significant impact on insect physiology throughout development. The accumulations of the deleterious physiological effects throughout low temperature exposure are collectively ... -
Eat to Reproduce: The Role of Diet Quantity on Honey Bee (Apis Mellifera) Caste Determination
(North Dakota State University, 2017)The received wisdom is that diet quality drives this queen-worker dichotomy, even though diet quantity differs significantly between queen and worker diet. Diet quantity likely determines honey bee caste; yet it has never ... -
Environmental Components of Phenotypic Variation Dietary and Trans-Generational Effects on Behavior
(North Dakota State University, 2017)Phenotypic variation, or the total variation in a trait, and its components are of great importance in the fields of evolutionary and behavioral ecology. Phenotypic variation can be broken down into both environmental and ... -
The Prairie Science Classroom: Original Outcome Durability and Impact on the Connection to Nature
(North Dakota State University, 2017)Environmental Education (EE) seeks to create an informed citizenry capable of taking action on environmental issues. Recent calls for more consistent evaluation of EE point to a need for more long-term evaluations as well ... -
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 ...
