The Influence Of Habitat And Individual Specialization On Mountain Lion (Puma Concolor) Hunting Strategy In A Multi-Prey System, Hannah B. Klugman

All Graduate Theses and Dissertations, Fall 2023 to Present

There is a growing recognition that animal species considered generalists (having a broad and varied diet), are actually specialists, a collection of individuals with different preferences and strategies known as specializations. The diet of a specialist depends on the variety and quantity of available food options, and their own ability to take what they need. Mountain lions (Puma concolor) are known for their ability and tendency to hunt large prey, such as elk (Cervus canadensis) and mule deer (Odocoileus hemionus), but despite the fact they overlap with other potential large prey, like feral horses …

Advancing Management Strategies For Two Promising Mason Bee Species (Osmia Ribifloris And Osmia Bruneri) For Berry Pollination, Miranda L. Jones

All Graduate Theses and Dissertations, Fall 2023 to Present

Bee management can broadly refer to human manipulation of one or multiple parts of a bee’s lifecycle. Managing honey bees, commonly referred to as beekeeping, is responsible for providing most pollination for global food crops. However, using more than one bee species for crop pollination can have many benefits. Benefits include better crop pollination and insurance in case one bee species underperforms or its population collapses. Some bees within the genus Osmia are already widely managed for crop pollination because their developmental lifecycle allows bee managers to readily deploy pollinating bees in sync with varying crop blooms, and for certain …

Perimenopause And Menopause: Understanding Utahns' Experiences, Cris Meier, Moth Huenemann, Cara Murray, Ashley Yaugher

All Current Publications

The first stage of menopause, known as perimenopause, is signaled by fluctuating or declining hormone levels, irregular menstruation, and the onset of symptoms such as hot flashes and mood changes. Menopause follows this phase, which is 12 consecutive months when no menstrual cycles occur in combination with hormone decline and experiencing additional symptoms (e.g., hot flashes, sleep disturbances).To better understand Utahns’ needs and preferences during menopause, Utah State University Extension researchers conducted a needs assessment to inform programming creation and delivery. This report details the results, identifying survey participants, women's sources of information, symptoms, and symptom management.

Harmful Algal Blooms: Risks For Food In Utah, Jose Brandao, Sarah Erwin, Stephanie Vaughn, Clare Entwistle

All Current Publications

Harmful algal blooms (HABs) are a problem because they can produce toxins that make water unsafe for people, animals, and the environment. In recent years, HABs have emerged as a growing concern in freshwater systems throughout Utah, including irrigation canals, reservoirs, and livestock ponds. HABs in freshwater are caused by cyanobacteria, also called blue-green algae. These microorganisms can release dangerous toxins that can harm swimmers, pets, and the food supply. Unlike foodborne pathogens, these toxins cannot be removed by boiling, cooking, or washing the food. Therefore, regular monitoring is essential to detect HABs early and reduce exposure risks. This fact …

Wildland Resources Student Research

Studies addressing seasonal changes in diet quality and hormones are important for understanding the interactions between ecology and physiology. We collected fecal samples from free-ranging adult female pronghorn (Antilocapra americana) to examine the relationships between indicators of nutrition and glucocorticoid activity. This occurred during three population-level, life-history-correlated sampling periods across five subpopulations. We evaluated nutrition via fecal nitrogen, fecal 2,6-diaminopimelic acid (DAPA), and assessed glucocorticoid activity using fecal glucocorticoid metabolites (FGM). We found positive relationships between fecal nitrogen and DAPA, whereas DAPA and fecal nitrogen with FGM varied in influence and strength, depending upon life history stage. Generally, …

Limitations And Alternative Applications Of Carbohydrate Fatty Acid Esters As Food Antimicrobials: A Review, Valeria Rodríguez Monge, Namhyeon Park

Nutrition, Dietetics, and Food Science Student Research

Carbohydrate fatty acid esters (CFAs) are nontoxic food additives with reported antimicrobial activity and growing interest as a potential safer alternative to conventional preservatives. However, their translation into real food systems remains limited. This review examined the main factors that restrict the antimicrobial performance of CFAs in foods and evaluated emerging alternative applications, particularly edible coatings, antibiofilm strategies, and synergistic combinations with other cleaning agents or processing techniques. Overall, the available evidence indicates that the antimicrobial efficacy of CFAs is often reduced in real food matrices compared with in vitro conditions. This loss of activity has been mainly associated with …

Additionally, by applying the principles of SCT, the curriculum incorporates scenario-based questions, opportunities to engage with peers, …

Seed Endophyte Bacillus Atrophaeus Colonizes Root And Shoot Tissues Providing Antifungal Activity During Wheat Seedling Establishment, Anagha Wankhade, Zhiting Xu, Ashlynn Clark, David Britt

Biological Engineering Student Research

Seed-associated endophytes become active during germination, playing important roles as early colonizers of plant tissues and contributing to plant health while residing in a protective niche. In this study, we characterized a wheat-derived bacterial isolate, JunSE1L, to determine its functional traits and ecological role in the plant microbiome. The isolate was identified as Bacillus atrophaeus based on 16S rRNA analysis. JunSE1L exhibited nutrient-dependent plasticity in colony architecture, forming robust hydrophobic biofilms and pellicles under rich nutrient availability while swarming and forming thin, often dendritic colonies under defined nutrition. JunSE1L produced highly surface-active compounds that lowered the surface tension of water …

This study examined physical activity strategies across a national sample of IPSE programs (n = 27) using a sequential mixed-method approach, including surveys and follow-up interviews, focusing on alignment with Self-Determination Theory (SDT). While 70.37% of programs offered formalized physical activity courses, all promoted physical activity informally. Common practices included peer mentorship (96.3% of programs), goal setting (100%), and …

Effects Of Mineral Supplementation On Ovine Performance, Forage Selectivity, And Rangeland Utilization In Southern Utah, Ryan A. Spurling

All Graduate Theses and Dissertations, Fall 2023 to Present

Sheep producers in the Intermountain West region of the US rely on productive rangeland ecosystems that vary widely in forage composition and nutrient availability. As such, supplementation is often necessary to offset dietary deficiencies. Soils and forages grown on rangelands are known to be highly variable in mineral content. Even so, a third to half of the producers in the Intermountain West choose not to provide a complete mineral supplement. Rangeland environments are often characterized by rugged geographical features that make optimal supplement placement difficult. New advances in technology have allowed us to measure individual animal intake on rangelands via …

Paucilactobacillus Wasatchensis Gas Production In Cheddar Cheese Through Symbiotic Amino Acid Metabolism With Lactococcus Lactis Starter Cultures, Niharika Mishra

All Graduate Theses and Dissertations, Fall 2023 to Present

Cheese is popular for its rich sensory notes and desirable physical attributes; however, the late blowing gas defect in cheddar cheese disrupts its appearance and can undermine its commercial value, for example if the late gas defect is severe, the block can crumble upon cutting, increasing cutting losses from 10% (non-defective) up to 50% (Donnely et al., 2014).

Paucilactobacillus wasatchensis cannot survive pasteurization (McMahon, D. J., et al., 2020); therefore, it enters the cheese as a contaminant during the cheesemaking process. Cheesemaking occurs in three stages: (1) curdling of milk by acidification through starter cultures, (2) separation of curd from …

Mechanisms Of Life History Trade-Offs In The Evolution Of Eusociality, Frances Katherine Hunter

All Graduate Theses and Dissertations, Fall 2023 to Present

When faced with stressors such as pathogen infection, organisms must invest energy in defense or risk death. Because resources are limited, mounting an immune response often comes at the expense of other costly activities such as reproduction. The costs of immunity are shaped by factors including behavior, nutrition, age, and evolutionary history.

Social insects (e.g., ants, bees, and wasps) offer a powerful system for studying these trade-offs because queens in these colonies appear to escape them—living long lives while reproducing prolifically. Bees, which include species that range from those which nest solitarily to those with complex social systems and many …

Effect Of Agroecological Feeding Systems Of Dairy Cattle On The Nutritional Composition Of Milk, Sree Bhavya Immadi

All Graduate Theses and Dissertations, Fall 2023 to Present

How food is produced can influence both its nutritional quality and its impact on the environment. In recent years, regenerative (agroecological) farming practices have gained attention for their potential to improve soil health, biodiversity, and the nutritional value of foods. In dairy production, these practices often involve growing more diverse forage crops, reducing soil disturbance, and relying less on monoculture-grown feed rations. However, there is still limited real-world evidence showing how these practices affect the nutritional composition of milk produced on commercial dairy farms.

This dissertation explores how regenerative feeding and feed production practices influence the nutritional quality of milk, …

Effects Of Tourist Feeding On The Gut Microbiome And Ecophysiology Of Endangered Northern Bahamian Rock Iguana (Cyclura Cychlura), Erin Lucy Lewis

All Graduate Theses and Dissertations, Fall 2023 to Present

The lifespan and reproduction of an animal depends on maintaining a healthy physiology. The proportion of individuals that survive to an age at which procreation can occur is important to long-term stability of populations and contributes to species survival. Health in an animal is measured in a variety of ways, including through monitoring of the body’s physiological systems, as well as its ability to respond to invading pathogens, and through the different types of bacteria present in the gut. Relationships among those different health metrics have been discovered in recent years and have been found to play important roles in …

Characterizing Metabolic Flux Of Plant Secondary Metabolites From Diverse Animal-Source Foods To Humans, Muhammad Ahsin

All Graduate Theses and Dissertations, Fall 2023 to Present

There is a popular saying: “You are what you eat.” But does this also mean, “You are what your food eats”? This dissertation explores that question by examining how farming practices shape the nutritional quality of meat—and what, if anything, those differences mean for the people who consume it. While modern livestock production and nutrition research often emphasize protein and fat, this work tests the idea that animals function as biological mediators, linking soil and plant conditions to human diets through the chemical composition of meat and milk. To evaluate this hypothesis, we tracked health-relevant plant compounds— phytonutrients—across the soil–plant–animal–human …
