Sperm Telomere Dynamics: Natural Variation and Sensitivity to Environmental Influences in House Sparrows (Passer domesticus)
(North Dakota State University, 2018)
Understanding the mechanisms that contribute to variation in lifespan is of central importance to diverse fields including life history theory. Although the causes of aging are not fully understood, telomere dynamics (length ...
Biogeochemistry of Wet Ecosystems from Root Zone to Landscape
(North Dakota State University, 2012)
The biogeochemistry of wetland ecosystems varies, causing them to act as sources, sinks, filters or transformers of nutrients and pollutants. Wetland plants play important roles in the cycling of elements in wet ecosystems. ...
Processing Trade-offs in a Cellulosic Biorefinery
(North Dakota State University, 2017)
Commercial scale cellulosic biorefineries face significant challenges to produce low-cost fermentable sugar from biomass. Biorefinery processing steps are interrelated and trade-offs between process parameters impact the ...
From Bray-Curtis Ordination to Markov Chain Monte Carlo Simulation: Assessing Anthropogenically-Induced andor Climatically-Induced Changes in Arboreal Ecosystems
(North Dakota State University, 2013)
Mapping forest resources is useful for identifying threat patterns and monitoring changes associated with landscapes. Remote Sensing and Geographic Information Science techniques are effective tools used to identify and ...
Habitat Use and Foraging Ecology of Bats in North Dakota
(North Dakota State University, 2016)
Habitat use is a key component to understanding the conservation needs of species. While an array of quantitative analyses for studying fine-scale habitat use and selection have been developed, such methods have rarely ...
The Effect of Zinc Oxide Nanoparticles on Plants, and on Host-Pathogen Interactions
(North Dakota State University, 2019)
Zinc oxide nanoparticles (ZnO NPs) are a type of engineered nanomaterial that is currently being explored for use in different aspects of agriculture. So far, research on this area is limited to evaluating the phenotypical ...
Multi-Element Composition of Triglochin Maritima L. from Contrasting Habitats including Hot Springs and Metal Enriched Areas
(North Dakota State University, 2011)
The aim of this PhD research was to study multi-element composition in wetland plants from contrasting habitats, including hot springs, temporary wetlands, and metal-rich areas. Triglochin maritima L. (seaside arrowgrass) ...
Determining Greenhouse Gas Emissions and Nitrogen Dynamics of Solid Beef Manure Applied to Fargo-Clay Soil of the Red River Valley
(North Dakota State University, 2018)
Land application of solid beef manure may prompt greenhouse gases (GHGs) - nitrous oxide (N2O), methane (CH4), and carbon dioxide (CO2) emissions. Nitrogen (N) in manure can also be lost through ammonia volatilization ...
Multi-Element Fingerprinting of River Sediments to Identify Diffuse Pollution Sources
(North Dakota State University, 2011)
This study was carried out in the Souris and Turtle Rivers in North Dakota. The aim of this study was to develop multi-element fingerprints of the Souris River and Turtle River sediments and to evaluate the suitability of ...
Influences of Climate Variability and Landscape Modifications on Water Dynamics, Community Structure, and Amphipod Populations in Large Prairie Wetlands: Implications for Waterbird Conservation
(North Dakota State University, 2014)
Northern prairie pothole wetlands provide crucial habitat for numerous waterbirds. However, wetland abundance and quality in the Prairie Pothole Region of North America has declined because of agricultural landscape ...
