Identification Of Biomarkers Of Sub-Lethal Algal Toxin Exposure In Atlantic Salmon (Salmo Salar) And Chinook Salmon (Oncorhynchus Tshawytscha) Using Differential Gene Expression Analysis, Brandon Ellingson

Biology Theses

Atlantic Salmon (Salmo salar) and Chinook Salmon (Oncorhynchus tshawytscha) are important culturally, recreationally, economically, and are a common aquaculture species in Canada and the United States. In the Pacific Northwest, blooms of toxic algae result in millions of dollars annually in losses for salmonid aquaculture producers. Blooms of harmful cyanobacteria produce microcystins which have been linked to net-pen liver disease which has large financial impacts on net pen salmon operations. Microcystin-LR, the most toxic variant, bioaccumulates in the liver and disrupts normal cellular activity by inhibiting protein phosphatases leading to deleterious effects on growth, immune status, and liver function. To …

Using Encrypted Genotypes And Phenotypes For Collaborative Genomic Analyses To Maintain Data Confidentiality, Tianjing Zhao, Fangyi Wang, Richard Mott, Jack Dekkers, Hao Cheng

Department of Animal Science: Faculty Publications

To adhere to and capitalize on the benefits of the FAIR (findable, accessible, interoperable, and reusable) principles in agricultural genome- to-phenome studies, it is crucial to address privacy and intellectual property issues that prevent sharing and reuse of data in research and industry. Direct sharing of genotype and phenotype data is often prohibited due to intellectual property and privacy concerns. Thus, there is a pressing need for encryption methods that obscure confidential aspects of the data, without affecting the outcomes of certain statistical analyses. A homomorphic encryption method for genotypes and phenotypes (HEGP) has been proposed for single-marker regression in …

Factors Affecting Forage Quality And The Subsequent Response In Production And Energy Metabolism In Lactating Jersey Cows, Kassidy Kate Buse

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Forage quality is the potential of a forage to produce a production response in animals. Because of how essential they are in dairy cattle rations, forages can have major influence on the behavior and production of dairy cattle. In experiment 1, the effect of forage fragility on the rumen environment and digestibility was evaluated. Increasing the inclusion of a less fragile forage led to greater rumen retention time, which resulted in lower rumen pH and greater NDF digestibility. Experiment 2 evaluated the effects of diets high in either corn silage or alfalfa haylage supplemented with either corn- or soy-based protein …

Food Science Faculty Articles and Research

Seafood mislabeling rates of approximately 20% have been reported globally. Traditional methods for fish species identification, such as DNA analysis and polymerase chain reaction (PCR), are expensive and time-consuming, and require skilled technicians and specialized equipment. The combination of spectroscopy and machine learning presents a promising approach to overcome these challenges. In our study, we took a comprehensive approach by considering a total of 43 different fish species and employing three modes of spectroscopy: fluorescence (Fluor), and reflectance in the visible near-infrared (VNIR) and short-wave near-infrared (SWIR). To achieve higher accuracies, we developed a novel machine-learning framework, where groups of …

Raccoon Spatial Ecology In The Rural Southeastern United States, Jacob E. Hill, Madison L. Miller, James L. Helton, Richard B. Chipman, Amy Gilbert, University Of Georgia, Guha Dharmarajan, Olin E. Rhodes Jr.

United States Department of Agriculture Wildlife Services: Staff Publications

The movement ecology of raccoons varies widely across habitats with important implications for the management of zoonotic diseases such as rabies. However, the spatial ecology of raccoons remains poorly understood in many regions of the United States, particularly in the southeast. To better understand the spatial ecology of raccoons in the southeastern United States, we investigated the role of sex, season, and habitat on monthly raccoon home range and core area sizes in three common rural habitats (bottomland hardwood, upland pine, and riparian forest) in South Carolina, USA. From 2018–2022, we obtained 264 monthly home ranges from 46 raccoons. Mean …

Effect Of Ploidy On Salinity And Temperature Tolerance In Early Life Stages Of The Eastern Oyster (Crassostrea Virginica), Christian Boudreaux, Jessica Pruett, Alexz Carpenter, Kristie Willett, Deborah Gochfeld

Honors Theses

The U.S. Gulf of Mexico contains the largest remaining wild oyster fishery in the world, but populations have declined in recent decades. A growing interest in off-bottom aquaculture that relies on triploid eastern oysters (Crassostrea virginica) has emerged in the Gulf region, yet these faster growing oysters suffer high mortality as adults during low salinity events (< 5 ppt) in warmer summer months. The combined effects of salinity and temperature stressors on early life stages of triploid oysters are unknown. Early life stages are particularly crucial to understand because triploid oysters do not occur naturally and must be reared in hatchery settings, requiring appropriate water conditions to yield the greatest survival and growth. Thus, we tested the effects of different temperatures (28oC and 32oC) and salinities (5, 10, and 15 ppt) on diploid and triploid oysters at three critical production stages: veliger, pediveliger, and spat. Veliger survival was significantly lower for triploids relative to diploid oysters at all experimental conditions, but triploid veligers had faster growth than diploids at 32oC and 15 ppt. Pediveliger settlement was not affected by ploidy type and only reduced at high temperature (32oC) and the lowest salinity (5 ppt). Diploid spat showed highest survival at 28oC and 15 ppt, while triploids survived best at 32oC and 15 ppt. Triploid spat attained greater shell height compared to diploids in our 6-day exposures, but growth decreased for both ploidies at lower salinities. At the salinity and temperature levels examined, diploid early life stages performed best at 28oC and 15 ppt, whereas triploids were more successful at 32oC and 15 ppt. A broader understanding of the combined effects of environmental stressors will improve the success of hatchery production yields and the resulting economic and environmental benefits of the oyster industry.

Examination Of The Prevalence And Behaviors Of Pathogenic And Spoilage Bacteria At Multiple Stages In The Meat Processing Chain, Samuel C. Watson

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

As long as there is food, there will also be bacteria that are capable of compromising the quality and safety of food. This dissertation aims to study bacteria capable of spoiling meat, causing illness, or both. The literature review summarizes the understanding of several bacterial pathogens, current issues in combating those pathogens in the food supply, and how spoilage Pseudomonas behave in the meat supply. Chapter 2 explored the impact of organic acid treatments on the spoilage microbiome of raw beef during extended storage. While Pseudomonas and Yersinia were both present in significant levels, Lactococcus was determined to be the …

Structural And Biological Characterization Of Two Freshwater Mussel Shells (Bivalvia: Unionidae), Hülya Şerefli̇şan

Turkish Journal of Zoology

The shell of a freshwater mussel (Mollusca: Bivalvia) is a composite biological material that plays an active role in maintaining ecosystem services. Mussel shells have variable structures both within and between species. In this study, the structural and biological characteristics of the shells of Potomida semirugata and Leguminaia wheatleyi were investigated in order to use freshwater mussel shells as a biological material. Close observation of the microstructure of the shells of the two common freshwater bivalves revealed a variation in construction from the outer periostracum to the inner nacreous layer. In P. semirugata, a polygonal arrangement with columnar prisms …

Exploring The Efficacy Of Rnai-Mediated Gene Knock-Down Via Oral Delivery Of Dsrna In The Colorado Potato Beetle (Leptinotarsa Decemlineata Say), Haneef Tari̇q, Ayhan Gökçe, Emre Aksoy, Emi̇nur Elçi̇, Allah Bakhsh

Turkish Journal of Zoology

RNA interference (RNAi) is a versatile genetic tool capable of selectively inhibiting the expression of any gene in a targeted organism. Its implementation holds great promise for safeguarding crops against insect pests and diseases. Vacuolar-ATPase represents an ideal target for RNAi-based pest management strategies since it is an enzyme essential for various physiological processes in insects. In this study, double-stranded RNA (dsRNA) was synthesized using an L4440 vector in Escherichia coli HT115 strain to silence the Vacuolar-ATPase proteolipid subunit mRNA in the Colorado potato beetle (Leptinotarsa decemlineata Say). To assess the effectiveness of RNAi, L. decemlineata larvae at different …
