Corn Hybrid Response to Skip-Row Planting Configurations and Plant Population in Western North Dakota
(North Dakota State University, 2011)
Management practices are needed for stable com (Zea mays L.) production in drought prone regions of western North Dakota. Analysis of weather data suggests areas like those near Mandan and Hettinger suffer severe drought ...
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, ...
Behaviors Mediate Aphid Interactions with Natural Enemies and the Environment
(North Dakota State University, 2016)
Behavior is a crucial component of ecology that mediates how animals interact with one another and with the environment. Behaviors can allow animals to avoid the harmful effects of things like competition, predation, and ...
Effects of Temperature on Pea Aphids, their Host Plants, and their Parasitoids
(North Dakota State University, 2018)
Temperature has the potential to alter every aspect of an organism’s biology. This is especially true when we focus on small ectotherms such as insects. Understanding the effects of temperature on insects is particularly ...
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 ...
Impact of Climate Parameters on Spring Wheat Yield in North Dakota
(North Dakota State University, 2016)
The impacts of climate change in agriculture is a growing concern. The agricultural sector plays a significant role in North Dakota's (ND) economy, and spring wheat contributes most to the economy. This study focuses on ...
Prairie Conservation and Reconstruction Studies in Communication, Application, and Education
(North Dakota State University, 2016)

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 ...
