Transcriptome Analysis Of Bifidobacterium Longum Strains That Show A Differential Response To Hydrogen Peroxide Stress, Taylor S. Oberg, Robert E. Ward, James L. Steele, Jeff Broadbent

Nutrition, Dietetics, and Food Sciences Faculty Publications

Consumer and commercial interest in foods containing probiotic bifidobacteria is increasing. However, because bifidobacteria are anaerobic, oxidative stress can diminish cell viability during production and storage of bioactive foods. We previously found Bifidobacterium longum strain NCC2705 had signifi- cantly greater intrinsic and inducible resistance to hydrogen peroxide (H₂O₂) than strain D2957. Here, we explored the basis for these differences by examining the transcriptional responses of both strains to sub-lethal H₂O₂ exposure for 5- or 60-min. Strain NCC2705 had 288 genes that were differentially expressed after the 5-min treatment and 114 differentially expressed genes …

Effect Of Shear Work Input On Steady Shear Rheology And Melt Functionality Of Model Mozzarella Cheeses, Prateek Sharma, Peter A. Munro, Tzvetelin T. Dessev, Peter G. Wiles, Robert J. Buwalda

Nutrition, Dietetics, and Food Sciences Faculty Publications

Model Mozzarella cheeses with varied amounts of shear work input were prepared by working molten cheese mass at 70 °C in a twin screw cooker. Rheology and melt functionality were found to be strongly dependent on total shear work input. A non-linear increase in consistency coefficient (K from power law model) and apparent viscosity and decrease in flow behaviour index (n from power law model) were observed with increasing amounts of accumulated shear work, indicating work thickening behaviour. An exponential work thickening equation is proposed to describe this behaviour. Excessively worked cheese samples exhibited liquid exudation, poor melting and poor …

Multi-Scale Environmental Filters And Niche Partitioning Govern The Distributions Of Riparian Vegetation Guilds, Nate Hough-Snee, Brian G. Laub, David M. Merritt, Arin Lexine Long, Lloyd L. Nackley, Brett B. Roper, Joseph Michael Wheaton

Watershed Sciences Faculty Publications

Across landscapes, riparian plant communities assemble under varying levels of disturbance, environmental stress, and resource availability, leading to the development of distinct riparian life-history guilds over evolutionary timescales. Identifying the environmental filters that exert selective pressures on specific riparian vegetation guilds is a critical step in setting baseline expectations for how riparian vegetation may respond to environmental conditions anticipated under future global change scenarios. In this study, we ask: (1) What riparian plant guilds exist across the interior Columbia and upper Missouri River basins? (2) What environmental filters shape riparian guild distributions? (3) How does resource partitioning among guilds influence …

Using A Rising Plate Meter To Determine Paddock Size For Rotational Grazing, Jennifer W. Macadam, Sara R. Hunt

All Current Publications

For rotational grazing of pastures to be most successful, it’s important to match pasture production to ruminant intake, because both can change during the grazing season. This publication shows how a rising plate meter can be used to calculate available pasture dry matter, allowing pasture managers to optimize pasture utilization and ruminant production on pasture.

Academic-Community Partnerships Effectiveness Evaluated Beyond The Ivory Walls, Rosemary M. Caron, Jessica Ulrich-Schad, Catherine C. Lafferty

Sociology, Social Work and Anthropology Faculty Publications

Community-based participatory research (CBPR) has furthered our understanding of the working principles required for academic-community partnerships to address persistent public health problems. However, little is known about how effective these partnerships have been in eliminating or reducing community-based public health issues. To contribute to the literature in this area, the authors conducted a survey of U.S. schools and programs in public health and community groups working with these academic partners to: (1) identify the most common local public health issues addressed; (2) examine the characteristics of the partnership and the actual or perceived benefits and challenges for each partner; (3) …

Large Wildlife Removal Drives Immune Defence Increases In Rodents, Hillary S. Young, Rodolfo Dirzo, Kristofer M. Helgen, Douglas J. Mccauley, Charles L. Nunn, Paul Snyder, Kari E. Veblen, Serena Zhao, Vanessa O. Ezenwa

Wildland Resources Faculty Publications

1. Anthropogenic disturbances involving land use change, climate disruption, pollution and invasive species have been shown to impact immune function of wild animals. These immune changes have direct impacts on the fitness of impacted animals and, also, potentially indirect effects on other species and on ecological processes, notably involving the spread of infectious disease. Here, we investigate whether the selective loss of large wildlife can also drive changes in immune function of other consumer species.
2. Using a long-standing large-scale exclosure experiment in East Africa, we investigated the effects of selective removal of large wildlife on multiple measures of immune function in …

Is Atmospheric Phosphorus Pollution Altering Global Alpine Lake Stoichiometry?, Janice Brahney, Natalie Mahowald, Daniel S. Ward, Ashley P. Ballantyne, Jason C. Neff

Watershed Sciences Faculty Publications

Anthropogenic activities have significantly altered atmospheric chemistry and changed the global mobility of key macronutrients. Here we show that contemporary global patterns in nitrogen (N) and phosphorus (P) emissions drive large hemispheric variation in precipitation chemistry. These global patterns of nutrient emission and deposition (N:P) are in turn closely reflected in the water chemistry of naturally oligotrophic lakes (r2 = 0.81, p < 0.0001). Observed increases in anthropogenic N deposition play a role in nutrient concentrations (r2 = 0.20, p < 0.05); however, atmospheric deposition of P appears to be major contributor to this pattern (r2 = 0.65, p < 0.0001). Atmospheric simulations indicate a global increase in P deposition by 1.4 times the preindustrial rate largely due to increased dust and biomass burning emissions. Although changes in the mass flux of global P deposition are smaller than for N, the impacts on primary productivity may be greater because, on average, one unit of increased P deposition has 16 times the influence of one unit of N deposition. These stoichiometric considerations, combined with the evidence presented here, suggest that increases in P deposition may be a major driver of alpine Lake trophic status, particularly in the Southern Hemisphere. These results underscore the need for the broader scientific community to consider the impact of atmospheric phosphorus deposition on the water quality of naturally oligotrophic lakes.

Aspen and climate change: Recent mortality portends bad news

William R. L. Anderegg

I grew up camping, fishing, and hunting in the aspen forests of southwestern Colorado. When I returned to these forests for my Ph.D. research, however, I saw that broad regions of the forests I remembered were dying, white-bark skeletons standing still against the blue mountain sky. I remember staring in shock at these forests and thinking, “What is going on here? What does this mean for the future of aspen?”

Examining The Association Between Children's Fruit And Vegetable Intake At And Away From School, Velarie Yaa Ankrah Ansu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Several school-based interventions aimed at increasing fruit and vegetables (FV) intake among children have demonstrated success in short-term interventions. The Fit Game is a school-based intervention aimed at encouraging children to consume increasing amounts of FV during a game, which is a narrative. Just as children are being encouraged to eat FV at school, so is it equally important for them to eat FV at home. Parents strongly influence the amount of FV children consume at home. The aim of this thesis is to examine associations between factors that influence consumption of fruits and vegetables at and away from school …

The Impact Of The Updated National School Lunch Program Meal Standards On Fruit And Vegetable Consumption Among Elementary School Students In Cache County Utah, Jillian C. Fox

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Due to the short time the updated National School Lunch Program standards have been in place since fall of 2012, few research studies have explored what effect these new standards have had on fruit and vegetable (F/V) consumption, particularly among elementary school students. Because the new standards require schools to offer students more F/V than before, researchers are interested to know if F/V consumption has indeed increased.

The participants in the study were enrolled in a program to motivate students to eat more F/V – the Food Dudes program. The results of the data analysis found that most students, regardless …

Late Taino Occupation Of Jamaica: A Zooarchaeological Analysis Of Faunal Materials From The Bluefields Bay Site, Diana M. Azevedo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

My thesis seeks to answer the broad questions: can early foragers alter marine resources in island settings and can archaeological data provide insights into these changes. These questions highlight two important issues. The first issue reflects the common belief that small-scale societies did not affect their environments. The second issue centers on growing concern over the collapse of fisheries across the globe.

To answer these questions, I use fish bones recovered from an archaeological site located in Belmont, Jamaica near the Bluefields Bay marine sanctuary. The Bluefields Bay site dates to the late Taíno occupation of Jamaica. The name Taíno …

Lifestyle Intervention In Emerging Adulthood: A Brief Acceptance-Based Behavioral Intervention With Young Adults, Spencer M. Richards

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Across the U.S., obesity and overweight represent a rapidly growing public health concern that have been associated with expensive and debilitating outcomes such as depression, cancers, diabetes, and other metabolic disorders, cardiovascular disease, and significant disruption in quality of life, in addition to the tremendous public health costs. The current study examined a brief, randomized-controlled trial of acceptance and commitment therapy (ACT) with overweight and obese young adults.

Study participants were randomly assigned to a 4-week experimental ACT group or an information control group, which received psychoeducational materials regarding lifestyle behaviors recommended by the Centers for Disease Control and Prevention …

Image Blur Detection With Two-Dimensional Haar Wavelet Transform, Sarat Kiran Andhavarapu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Efficient detection of image blur and its extent is an open research problem in computer vision. Image blur has a negative impact on image quality. Blur is introduced into images due to various factors including limited contrast, improper exposure time or unstable device handling. Toward this end, an algorithm is presented for image blur detection with the use of Two-Dimensional Haar Wavelet transform (2D HWT). The algorithm is experimentally compared with two other image blur detection algorithms frequently cited in the literature. When evaluated over a sample of images, the algorithm performed on par or better than the two other …
