The Effects Of Raising A Child With Companion Animals, Abby Murcray
The Effects Of Raising A Child With Companion Animals, Abby Murcray
Fall Student Research Symposium 2022
What were the effects on children who were raised with companion animals? As someone who has grown up with companion animals most of my life, I wanted to learn what impact the animals had on my growth and development. The research was conducted using library and internet resources to locate both primary and secondary resources. For this study, I looked at specific studies done on children that are surrounded by companion animals versus those that are not, using mostly Utah State's Academic Search Ultimate to find my sources. Raising a child with a domestic animal benefits a child in many …

A Helping Hand Through Dying Light, Jason Moessing
Fall Student Research Symposium 2022
Many people go into martial relationships with a previous history of childhood maltreatment. This can cause marital problems later on in the marriage if steps are not taken to help the individual heal from the abuse. To find relevant information to help in this understanding, a diverse amount of websites were researched including blogs, scholarly articles, data observations, and therapy websites. Past history of childhood maltreatment can cause lasting problems in marriages, but when couples decide to find help those marriages can become beautiful symbols of love. Men and women have been found to react differently to different types of …
Facilitative Parasitization Of Brown Marmorated Stink Bug Eggs Between Native And Invasive Trissolcus Wasps, Zachary Ross
Facilitative Parasitization Of Brown Marmorated Stink Bug Eggs Between Native And Invasive Trissolcus Wasps, Zachary Ross
Fall Student Research Symposium 2022
The Brown Marmorated Stink Bug (Halyomorpha halys, BMSB) is an extremely successful invasive species with over 300 different host plants ranging from ornamental to agricultural species. One of the primary controls of BMSB in their native range is the parasitoid wasp Trissolcus japonicus (T.j). While T.j has the ability to control BMSB populations, native species of parasitoid wasp have also been documented targeting BMSB eggs, although with minimal success. The primary objective of this study was to determine whether or not a beneficial facilitative relationship existed between the invasive Trissolcus japonicus and the native egg parasitoid Trissolcus euschisti (T. eu). …
Isolation Of Bacterial And Fungal Microbes From The Rhizosphere Of Shepherdia Utahensis 'Torrey', Ty Wilson, Katie Hewitt
Isolation Of Bacterial And Fungal Microbes From The Rhizosphere Of Shepherdia Utahensis 'Torrey', Ty Wilson, Katie Hewitt
Fall Student Research Symposium 2022
My presentation is on the Isolation of Bacterial and Fungal Microbes from the Rhizosphere of Shepherdia x utahensis 'Torrey' also known as Hybrid Buffaloberry. Hybrid Buffaloberry is a combination between two varieties native to the Intermountain West: Shepherdia argentea, a highly drought tolerant variety, and Shepherdia rotundifolia, a common more aesthetically pleasing variety. Both native varieties are well documented to have nodule forming microbes that help aid their development in such harsh conditions. We acquired our Rhizosphere sample by shaking the roots and nodules from our sample in a phosphate buffer and serially diluted it to a useful concentration. We …
Multimodel Courtship Signaling In The Family Hylidae, Addie Lloyd
Multimodel Courtship Signaling In The Family Hylidae, Addie Lloyd
Fall Student Research Symposium 2022
It is becoming increasingly obvious that species' courtship is more complex than originally thought. Hundreds of studies have described courtship systems focusing on a single trait, but we know many species have multiple signaling methods (Hebets, 2005). Multimodal courtship describes a composition of signals covering different sensory modalities, including visual, auditory, and tactile. Is having multiple courtship methods better than just one? This study focused on two types of signaling- sexual dichromatism and the presence of vocal sacs- in the family Hylidae. The goal was to determine the preferred signaling methods and their evolutionary relationship. We predicted that most species …
Electrochemical Dna-Based Biosensor For The Detection Of Dnase I Activity For Potential Application For Crispr-Cas Based Biosensor, Tessa Siler
Fall Student Research Symposium 2022
Dioxyribonuclease I (DNase I, DC 3.1.21.1) is an enzyme that cleaves DNA at phosphodiester linkages. The deviation of DNase I activity is a significant important marker for several diseases. For example, the lower activity of DNase can cause arthritis and several other autoimmune diseases, whereas higher DNase I activities are observed in patients with breast and oral cavity cancers. This makes monitoring the DNase I activity important for clinical and point-of-care diagnostics.Several methods were developed to assay DNase I activity, such as the enzyme-linked immunosorbent assay (ELISA), fluorimetric assays, radial immunodiffusion (RID) and radial enzyme diffusion (RED) assays. These methods …
The Effect Of Fish Oil Supplementation And A Western-Type Diet On Gut Health, Marcus Hayden
The Effect Of Fish Oil Supplementation And A Western-Type Diet On Gut Health, Marcus Hayden
Fall Student Research Symposium 2022
Colorectal cancer (CRC) is one of the most prevalent cancers worldwide and has increased incidence in more developed countries (Parkin et al., 2005). Diets in more developed and Westernized countries, where CRC is more prevalent, tend to be energy-dense and nutrient deficient. Discovering which food patterns inhibit inflammation matters because the duration of colitis is a risk factor for CRC. Deficiencies in an American diet led to decreased gut microbiota diversity and increased prevalence of colitis. A key component of colon health is the microbiome. Dietary bioactive compounds change the composition of the microbiome. Docosahexaenoic acid (DHA) is a promising …
Alzheimers Disease: The Effects It Has On Everyone Involved, Mckinlee Denson
Alzheimers Disease: The Effects It Has On Everyone Involved, Mckinlee Denson
Fall Student Research Symposium 2022
Alzheimers Disease is hard on everyone who is involved. With being a caregiver in my past I understand how hard it is taking care of someone with Alzheimers Disease. Family plays a big role in the life of those who have Alzheimer's Disease. On average 11 million Americans provide 15.3 billion hours of unpaid work. I believe that we need to find relief for those who give endless hours to support their loved ones with AD. Many people are impacted by Alzheimers Disease this can be friends, family, and medical caregivers. Alzheimers is especially hard on those who have the …
Expressing And Purifying Type Iv Crispr Accessory Proteins, Alivia Jolley
Expressing And Purifying Type Iv Crispr Accessory Proteins, Alivia Jolley
Fall Student Research Symposium 2022
CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)-Cas (CRISPR-associated) adaptive immune systems defend bacteria and archaea against phages, plasmids, and other mobile genetic elements. Each Type IV CRISPR system contains a subtype-specific gene and is hypothesized to be essential for function. The Type IV-A system encodes ATP-dependent 5'-3' DNA helicase called CasDinG, while the Type IV-B systems encode a putative pyrophosphatase named CasCysH. Here we investigate the function of the type IV CRISPR systems by expressing, purifying, and characterizing the accessory proteins from the type IV systems. This project is a first step towards understanding the structure and mechanism of type …
Modeling Plant Migration In A Varying Landscape, Seth Corbridge
Modeling Plant Migration In A Varying Landscape, Seth Corbridge
Fall Student Research Symposium 2022
It is important to predict how plants will migrate under the changing conditions associated with climate change. In particular, finding instances where plants migrate quickly will help in predicting which plant species are in danger of being outpaced by climate change. Many existing models for plant migration assume a homogeneous landscape, however this is not always fully realistic. This project considers a model incorporating landscape heterogeneity for modeling plant migration. By forming a landscape of varying patches of high and low motilities, it is shown how a varying landscape can lead to increased migration rates in some cases when compared …
Mechanical Properties Of Hagfish Protein Hydrogels, Hayden Johns
Mechanical Properties Of Hagfish Protein Hydrogels, Hayden Johns
Fall Student Research Symposium 2022
Hagfish are ancient animals that eject a strong slime when attacked by predators. This slime is composed of intermediate filaments that contribute to its incredible strength.To defend against foes, the Navy launches plastic ropes into the propellors of enemy warships in order to decrease the thrust of motors. In an effort to find a more biodegradable solution, the utilization of hagfish slime has shown great promise in stopping propellors.We hope to understand how the slime withstands the impact of a quickly rotating propellor, while simultaneously reducing the propellor's thrust. What specific mechanical properties allow for this phenomena? From this research …
Relationship Between Protein And Secondary Metabolite Content In Congeneric Tropical Shrubs, Anna Billings
Relationship Between Protein And Secondary Metabolite Content In Congeneric Tropical Shrubs, Anna Billings
Fall Student Research Symposium 2022
Secondary metabolites are important defensive compounds found in plants which deter pests and pathogens and play an important role in defending against herbivory and seed predation. The role of secondary metabolites in fruits is complex as plants must defend the costly fruits while also successfully attracting dispersers. Protein investment into fruits is costly for plants but can serve as a reward to dispersers. In this experiment, we examined the protein content of plant tissues and compared it with the secondary metabolite content. We extracted and measured protein content of leaf and fruit pulp tissues from 15 species of Psychotria (a …
