Applications in plant breeding : end-use quality, tissue culture propagation systems, and outreach for K-12 education

Creator:: Halstead, Margaret A.
Abstract:: This thesis consists of five chapters: a general introduction, two manuscripts, a collection of published lesson plans, and a general conclusion. The works collected herein are united by the common theme of practical applications in plant breeding. The first manuscript reports a study performed on five malting barley lines grown...

Assessing Exposures and Simplifying Complex Mixtures of SVOCs for Hazard Characterization using Alternative Model Systems

Creator:: Rivera, Brianna N.
Abstract:: Throughout their lifetime individuals are exposed to complex mixtures of chemicals. The study of chemical mixtures is an internationally recognized research priority, but seemingly complex challenge. To reduce the intricacy of studying mixtures, researchers have identified different prioritization methods based on exposure or the toxicity of chemicals. However, understanding the...

Developing a hemp dihaploid protocol

Creator:: Murphy, Sean K.
Abstract:: Cannabis production has gained popularity over the last 10 years. There is a growing demand for true-to-type grain, fiber, and resin crops. Breeding for homozygous trait development with traditional methods can take as long as 8 years. With dihaploid breeding, homozygosity can be achieved in 2 generations saving breeders time...

Ontology-based standardized phenotype and gene annotations from six model/crop species

Creator:: Johnson, Ethan
Abstract:: The data retrieved from gt;momic sequencing techniques provides the raw information required to infer the basis of mutations and their resulting phenotypes, wherein plant ontologies can be utilized in annotating said phenotypes using a common, shared vocabulary. By relating mutant genes of similar phenotypes both within and between plant species,...

Big fishery, big data, and little crabs : using genomic methods to examine the seasonal recruitment patterns of early life stage dungeness crab (Cancer magister) in the California Current ecosystem

Creator:: Lee, Elizabeth M. J. and O'Malley, Kathleen
Abstract:: The California Current Ecosystem (CCE) is a dynamic marine ecosystem from which many socioeconomically important fisheries species are harvested. Here, a genotyping-by-sequencing (GBS) approach was used to examine genomic variation in an early life stage (megalopae) of the Dungeness crab (Cancer magister), which constitutes the most valuable single-species commercial fishery...

Factors Affecting Black-footed Ferret Populations within the Great Plains Region of North America: A Case Study

Creator:: Hodges, Rodney J.
Abstract:: The black-footed ferret is a meso-predator within the Great Plains region of North America. Before the 1900s, black-footed ferret populations were self-sustaining in large ecological patches throughout the geographical range of the Great Plains. During the 1900s, various factors such as the systematic extermination of prairie dogs (the primary food...

Ecology and Distribution of Blue Whales in New Zealand Across Spatial and Temporal Scales

Creator:: Barlow, Dawn R.
Abstract:: The distribution of mobile marine predators often reflects underlying dynamic ecological processes. The geographical focus of this PhD is the South Taranaki Bight (STB) of New Zealand, where wind-driven coastal upwelling generates productivity and prey to support a blue whale foraging ground. The STB is also New Zealand’s most industrial...

Inheritance and Allelism Among the B genes in Cucurbita moschata

Creator:: Wilson, Casey K.
Abstract:: One of the most economically important genes in squash (Cucurbita spp.) is the B gene which conditions precocious depletion of chlorophyll in preanthesis fruit. The B genes are found naturally occurring in at least three of the five domesticated species of Cucurbita, including C. pepo, C. maxima and, most recently...

A Literature Review: A Brief History of Sea Lion Management and Conservation

Creator:: Huffman, Nancy Celeste
Abstract:: Today, there are six extant species of sea lion around the world, with the seventh (the Japanese sea lion) already having gone extinct due to a lack of proper conservation management. Because each of the surviving 6 sea lion species differ slightly in their anatomy, behavior, reproduction, and local habitats,...

Larval development in the Pacific oyster and the impacts of ocean acidification : differential genetic effects in wild and domesticated stocks

Creator:: Durland, Evan, Pierre De Wit,, Meyer, Eli, and Langdon, Chris
Abstract:: The adaptive capacity of marine calcifiers to ocean acidification (OA) is a topic of great interest to evolutionary biologists and ecologists. Previous studies have provided evidence to suggest that larval resilience to high pCO2 seawater for these species is a trait with a genetic basis and variability in natural populations....
