Factors Affecting White-Tailed Deer-Browsing Rates On Early Growth Stages Of Soybean Crops, Gregory M. Colligan, Jacob L. Bowman, Joseph E. Rogerson, Bruce L. Vasilas

Human–Wildlife Interactions

White-tailed deer (Odocoileus virginanus) damage to soybean crops is a concern for soybean producers. Although researchers have documented decreases in the intensity of deer-browse on soybean plants as the growing season progresses, an understanding of the mechanisms driving the decrease in deer-browse is necessary for reduction and mitigation of deer damage to soybean crops. We tested 4 hypotheses to determine why deer-browse rates decrease 3 weeks after plant emergence: (1) plant phenology affects plant palatability; (2) diet change occurs; (3) deer damage induces a plant response making soybean leaves less palatable: and (4) deer consume fewer leaves but …

Preference Of White-Tailed Deer For Corn Hybrids And Agricultural Husbandry Practices During The Growing Season, Joshua A. Delger, Kevin L. Monteith, Lowell E. Schmitz, Jonathan A. Jenks

Human–Wildlife Interactions

Damage to field corn (Zea mays) by white-tailed deer (Odocoileus virginianus) can be substantial, resulting in millions of dollars lost annually. Numerous methods exist to minimize deer depredation, but all have met with varying degrees of success. Currently, little information is available on preference of white-tailed deer for corn hybrids during the growing season and how that preference might affect depredation patterns. We used adult female white-tailed deer in captivity to study the effect of herbicide treatments on deer-use (treatment versus no treatment) of corn in 2005 and to document preference among specific corn hybrids in …

Feed Depredation By European Starlings In A Kansas Feedlot, Brandon E. Depenbusch, James S. Drouillard, Charles D. Lee

Human–Wildlife Interactions

Confinement cattle-feeding operations have been associated with large populations of starlings (Sturnus vulgaris) during the winter months. Starlings can eat nearly 1 kg each of feed per month (Besser et al. 1968). In the first of our 2 studies, we evaluated feed selection and feed depredation by starlings using 5 concentrate-based cattle finishing diets. Four diets evaluated were in traditional meal-type form, and 1 diet was an extruded pellet. We placed rations into a section of the feed trough that we made accessible to starlings but not to cattle. Of the original 13.6 kg of steam-flaked corn and …

Livestock And Domestic Dog Predations By Wolves In Michigan, Justin L. Edge, Dean E. Beyer Jr., Jerrold L. Belant, Mark J. Jordan, Brian J. Roell

Human–Wildlife Interactions

Wolves (Canis spp.) have recolonized the Great Lakes region and expanded into agricultural areas where there is increasing concern of conflict with livestock. We documented 121 wolf predation events on captive or domestic animals in the Upper Peninsula (UP) of Michigan between April 1996 and April 2009. We investigated the relationship between annual wolf abundance and predation events, seasonality of predations on livestock, and the association between previous winter severity and predations on livestock. The annual number of predations on livestock increased with wolf abundance, and overall, predations on cattle and calves increased during calving season. We observed a …

Factors Governing Risk Of Cougar Attacks On Humans, David Mattson, Kenneth Logan, Linda Sweanor

Human–Wildlife Interactions

Since the 1980s wildlife managers in the United States and Canada have expressed increasing concern about the physical threat posed by cougars (Puma concolor) to humans. We developed a conceptual framework and analyzed 386 human– cougar encounters (29 fatal attacks, 171 instances of nonfatal contact, and 186 close-threatening encounters) to provide information relevant to public safety. We conceived of human injury and death as the outcome of 4 transitions affected by different suites of factors: (1) a human encountering a cougar: (2) given an encounter, odds that the cougar would be aggressive; (3) given aggression, odds that the …

Growth Of Lactobacillus Paracasei Atcc 334 In A Cheese Model System: A Biochemical Approach, M. Budinich, I. Diaz-Muniz, H. Cai, S. A. Rankin, Jeff Broadbent, J. L. Steele

Nutrition, Dietetics, and Food Sciences Faculty Publications

Growth of Lactobacillus paracasei ATCC 334, in a cheese-ripening model system based upon a medium prepared from ripening Cheddar cheese extract (CCE) was evaluated. Lactobacillus paracasei ATCC 334 grows in CCE made from cheese ripened for 2 (2mCCE), 6 (6mCCE), and 8 (8mCCE) mo, to final cell densities of 5.9 × 108, 1.2 × 108, and 2.1 × 107 cfu/mL, respectively. Biochemical analysis and mass balance equations were used to determine substrate consumption patterns and products formed in 2mCCE. The products formed included formate, acetate, and d-lactate. These data allowed us to identify the pathways likely used and to initiate …

Genetic Diversity In Proteolytic Enzymes And Amino Acid Metabolism Among Lactobacillushelveticus Strains, Jeff Broadbent, H. Cai, R. L. Larsen, J. E. Hughes, D. L. Welker, V. G. De Carvalho, T. A. Tompkins, Y. Ardo, F. Vogensen, A. Delorentiis, M. Gatti, E. Neviani, J. L. Steele

Nutrition, Dietetics, and Food Sciences Faculty Publications

Lactobacillus helveticus CNRZ 32 is recognized for its ability to decrease bitterness and accelerate flavor development in cheese, and has also been shown to release bioactive peptides in milk. Similar capabilities have been documented in other strains of Lb. helveticus, but the ability of different strains to affect these characteristics can vary widely. Because these attributes are associated with enzymes involved in proteolysis or AA catabolism, we performed comparative genome hybridizations to a CNRZ 32 microarray to explore the distribution of genes encoding such enzymes across a bank of 38 Lb. helveticus strains, including 2 archival samples of CNRZ 32. …

Hazelnuts In The Home Orchard, Taun Beddes, Steve Renquist, Michael R. Kuhns, Michael Pace

All Current Publications

Hazelnuts or filberts can be useful crops for home food production or hobbyists in Utah. Several species have nuts with good flavor, with American, beaked and certain hybrid types most likely to produce consistently. Though European hazelnut with its large nuts is very common commercially, this species blossoms earlier than others and is more likely to have flowers damaged or destroyed by unseasonably cold weather. All hazelnut species benefit from being planted in frost protected areas to increase the likelihood of consistent nut production.

In Utah, hazelnuts grown for nut production are usually maintained as shrubs, with an oval or …

Effects Of Three Emulsion Compositions On Taste Thresholds And Intensity Ratings Of Five Taste Compounds, J. E. Thurgood, Silvana Martini

Nutrition, Dietetics, and Food Sciences Faculty Publications

This study assessed the effects of three emulsified systems on taste thresholds and the near-threshold taste intensities of the five tastes (sweet, sour, salty, bitter and umami). Emulsions were formulated with different lipid chemical compositions. Lipid addition in an emulsified form significantly increased thresholds for sour and bitter tastes produced by citric acid and quinine hydrochloride, respectively. No significant differences were found in the threshold levels in emulsions formulated with different lipids for the five tastes evaluated. In general, for the same tastant concentration, taste intensities for sour and bitter tastes were lower in emulsions compared with the aqueous solutions, …

Parental Attitudes And Perceptions Related To Their Children's Physical Activity And Eating Patterns, Megan Leatham Dubois

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Children's physical inactivity and poor eating patterns have received a great deal of attention in our country and worldwide. Studies have been conducted to identify determinates related to children's physical activity and eating patterns and to identify strategies for promoting positive behaviors. Parental support is a well-accepted determinate of children's physical activity and eating patterns. However, little qualitative research has been done to determine parental attitudes and perceptions related to this critical role.

First, the study sought to gain a greater understanding of parental perspectives on their children's physical activity and eating patterns. Second, the study examined parental attitudes and …

Interclonal Variation Of Primary And Secondary Chemistry In Western Quaking Aspen And Its Influence On Ungulate Selection, Damon A. Winter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Quaking aspen (Populus tremuloides) clones within close proximity to one another can exhibit drastically different levels of browsing by ungulates. The objectives of this study were to (1) determine interclonal differences in plant chemistry between adjacent clones exhibiting different degrees of herbivory which may influence the browsing behavior and patterns of ungulates, and (2) determine if correlation exists in the levels of salicortin and tremulacin between current year's suckers and current year's growth on older trees. This second objective was meant to indicate a protocol for land managers for identifying clones meriting increased protection from herbivory after treatment …

Enhancing Out-Of-Season Production Of Tomatoes And Lettuce Using High Tunnels, Britney L. Hunter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The growing season for vegetable crops is limited by freezing temperatures in arid high elevation climates such as northern Utah. Logan, Utah (41.73 N, 111.83 W, 1382 m elevation) has a short, variable growing season with an average frost-free period of 135 days. Extending the growing season provides growers with an opportunity to extend revenue into a normally unproductive period and benefit from out-of-season price premiums. High tunnels have been used to effectively extend the growing season for numerous crops by providing cold temperature protection. However, limited high tunnel research has been performed in arid high elevation regions that experience …

A Comparison Of Muscle Activity Responses Of Adults And Children During Whole Body Vibration, Dustin Blair Nash

Undergraduate Honors Capstone Projects

Results of recent studies have suggested that attenuation and transmissibility of WBV in adults and children are similar, but due to anatomical differences, it is hypothesized that children employ different strategies. One suggested strategy is that of muscle tuning, whereby muscle activity levels are adjusted to control potentially dangerous accelerations produced by vibration resonance. The purpose of the study was to compare muscle activity responses between children and adults exposed to whole body vibration. It was hypothesized that the muscle activity in children would be greater than that in adults due to muscle tuning strategies. Eleven adults and fourteen children …

A Multi-Component School-Based Intervention Aimed At Increasing Vegetable Preference And Intake Among Elementary-Aged Children, Elizabeth Strasser

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study aimed to implement and assess a school-based multi-component intervention aimed at increasing elementary school-aged children's knowledge of, preference for, and intake of vegetables. The multi-component intervention included lunchroom exposure, nutrition curriculum in the classroom, after school program vegetable curriculum, family friendly nutrition newsletter, vegetable fair and parent cooking class. Lunchtime vegetable consumption was assessed by direct observation. Changes in preference, attitude, and knowledge were assessed using a pre- and post-intervention survey.

The multi-component intervention was implemented at Canyon Elementary during the 2008-2009 school year. Classroom teachers provided 20 minutes of nutrition education to students in grades one through …

Fat Taste Transduction In Mouse Taste Cells: The Role Of Transient Receptor Potential Channel Type M5, Pin Liu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A number of studies have demonstrated the ability of free fatty acids to activate taste cells and elicit behavioral responses consistent with there being a taste of fat. Here I show for the first time that long chain unsaturated free fatty acid, linoleic acid, depolarizes taste cells and elicits a robust intracellular calcium rise via the activation of transient receptor potential channel type M5. The linoleic acid-induced responses depend on G protein-phospholipase C pathway indicative of the involvement of G protein-coupled receptors in the transduction of fatty acids. Mice lacking transient receptor potential channel type M5 exhibit no preference for …

Dietary Milk Fat Globule Membrane Reduces The Incidence Of Aberrant Crypt Foci In Fischer-344 Rats And Provides Protections Against Gastrointestinal Stress In Mice Treated With Lipopolysaccharide, Dallin R. Snow

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Milk fat globule membrane surrounds the fat droplets of milk. It is a biopolymer containing primarily membrane glycoproteins and polar lipids which contribute to its properties as a possible neutraceutical. The aims of the studies were to determine if dietary milk fat globule membrane: (1) confers protection against colon carcinogenesis; and (2) promotes gut mucosal integrity while decreasing inflammation compared to diets containing corn oil or anhydrous milk fat.

Aim 1. Three dietary treatments differing only in the fat source were formulated: (1) AIN-76A, corn oil; (2) AIN-76A, anhydrous milk fat; and (3) AIN-76A, 50% milk fat globule membrane, 50% …

An Investigation Of The Utilization Of Soil Water And Nitrogen Among Diverse Forage Plant Species And Mixtures, Sallee Reynolds

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Species diversity achieved by adding novel functional groups (warm-season grasses and non-leguminous forbs) to pasture land, along with traditional grasses and legumes, could aid in the capture of nutrients and water in pasture systems by offering complementary rooting architecture to aid in water and nitrogen uptake and decrease nitrogen leaching. Because these species may differ from commonly used grasses and legumes in their seasonal pattern of productivity, they could also extend or enhance growing-season productivity. The goal of this project is to better understand the role of plant diversity in 1) nitrogen use and 2) distribution of rooting dynamics and …

Ecology And Management Of A High Elevation Southern Range Greater Sage-Grouse Population: Vegetation Manipulation, Early Chick Survival, And Hunter Motivations, Michael R. Guttery

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

My research provided new information concerning the management, ecology, and conservation of greater sage-grouse (Centrocercus urophasianus). I report the results of an experiment using strategic intensive sheep grazing to enhance the quality of greater sage-grouse brood-rearing habitat. Although forb cover, an important component of brood-rearing habitat, responded positively to the grazing treatment, the response of other habitat variables was suppressed because the plots were not protected from domestic and wild herbivores during the years following the treatments. Measurements taken in grazing exclosures confirmed that herbivory by both large and small animals had significant impacts on vegetation. However, despite …

Young's Schema Theory: Exploring The Direct And Indirect Links Between Negative Childhood Experiences And Temperament To Negative Affectivity In Adulthood, Mark S. Jesinoski

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Young's schema theory offers a theoretical approach that relates negative childhood experiences, temperament, and early maladaptive schema, to the experience of negative affect and/or depression in adulthood. However, despite the widespread use of schema therapy in clinical practice, little research has explored the pathways theorized by Young. This study explored the pathways posited by Young and colleagues looking at the direct and indirect relationships among negative childhood experience, temperament, early maladaptive schema, and the experience of negative affect in adulthood. Self-report data were collected from 365 undergraduate students. Results demonstrated consistent and robust direct relationships between temperament and negative affect, …

Spatial Epidemiology Of Birth Defects In The United States And The State Of Utah Using Geographic Information Systems And Spatial Statistics, Samson Y. Gebreab

In Chapter 3, treatments consisted of: 1) 100% alfalfa hay (AH), 2) 50% AH and 50% birdsfoot trefoil hay (dry matter (DM) basis; AHBFTH), and 3) 100% birdsfoot trefoil hay (BFTH). Three replicated runs lasted 8 d each, with the first 5 d allowed for microbial adaptation to the diets, and 3 d for data collection and sampling. Methane, neutral detergent fiber (NDF) …

The Essential Structure Of Compulsive Buying: A Phenomenological Inquiry, Letty Workman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

While many jokes and sales of specialty merchandise have been made that make light of consumers who frequently shop and buy (e.g., "When the going gets tough, the tough go shopping," or "I am a shopaholic"), for 18 million Americans suffering from compulsive buying, the process of shopping and buying has caused their lives to literally go out of control. The outcomes of this disease for individuals, families, and business are all negative. In a marketing era of social responsibility, if marketers either knowingly or unknowingly encourage increased consumption among compulsive buyers, potential negative outcomes stand to impact others well …
