Migratory Ecology and Wing Morphology of North Dakota Bats
(North Dakota State University, 2019)
Understanding links between a species’ migratory behavior, wing morphology, and foraging strategy can provide insight into factors driving the evolution of behavioral and ecological responses. The first chapter of this ...
The Effects of Salinity on Canadian Toad (Anaxyrus hemiophrys) Larvae and Post-Metamorphic Juveniles
(North Dakota State University, 2021)
Sodium Chloride (NaCl) production in the United States is at an all-time high. As weather patterns become harsher through climate change and demands on energy and agriculture increase, evidence of long-term NaCl exposure ...
Late Quaternary Glacier and Climate Change in the Northeastern Great Basin
(North Dakota State University, 2021)
This thesis presents a cosmogenic 10Be exposure chronology for glacial moraines within the Baker Creek valley alongside water balance and climate modeling of Pluvial Lakes Franklin and Clover. These records further limit ...
Effects of Zinc Oxide Nanoparticles and Carbon Nanotubes in Important Crop Species: Plant Growth and Element Uptake
(North Dakota State University, 2021)
Engineered nanomaterials (ENMs) have been developed for various uses in the agriculture industry. The effects of ENMs in plant systems are not yet fully understood. Some studies have reported the different effects of ENMs ...
Paleoclimatic Interpretation of the Moorhead Low Water Phase of Glacial Lake Agassiz in the Southern Basin based on Fossil Coleoptera Assemblages
(North Dakota State University, 2009)
See submission document for full abstract.
Chemical Repellents for Reducing Blackbird Damage on Mature Sunflowers: The Importance of Plant Structure and Avian Behavior in Field Applications
(North Dakota State University, 2019)
Across North America, blackbirds (Icteridae) depredate high-energy crops, such as sunflower (Helianthus annuus), placing an economic burden on producers. Chemically-defended crops, in the form of human-applied repellents, ...
Mid-Wisconsinan Climate Reconstruction Based on Fossil Beetles from Six Mile Creek, Ithaca, New York
(North Dakota State University, 2018)
The history of the Mid-Wisconsinan sub-stage in northeastern North America is one of large climatic oscillations. Fossil beetles were extracted from two horizons at the Six Mile Creek site, New York. A total of 738 individuals ...
Influences on Fungal Community Composition in Roots and Soil of Coffee and Other Rubiaceae in Costa Rica
(North Dakota State University, 2019)
Belowground fungi interact with plants directly as pathogens and mutualists, and indirectly as nutrient cyclers, yet the factors governing fungal community composition are poorly understood. Here I examined root and soil ...
Evidence of Inbreeding and Divergence in the Western Prairie Fringed Orchid (Platanthera praeclara)
(North Dakota State University, 2018)
The conversion of grasslands to agriculture land has made the tall grass prairie one of the world’s most endangered ecosystems and has played a key role in the decline of one particular species of rare endangered orchid, ...
Antipredator Behavior and Morphology in Isolated Cyprinodont Fishes
(North Dakota State University, 2018)
For desert fishes in the American Southwest, predation by invasive species has triggered massive population declines for decades, leaving researchers speculating on the underlying cause. It has been shown that Post-Pleistocene ...
