Housing & Residence Life Impact Report: Fall 2017 To Spring 2018, Hayden Hoopes, Alan Andersen, Kirk Bird, John Bostock, Whit Milligan, Amanda M. Hagman

Publications

Introduction: Living on campus is considered a high impact practice for student success. Student success is believed to emerge from “the amount of physical and psychological energy that the student devotes to the academic experience” (Astin, 1984), housing and residence life programming facilitates this type of devotion. However, creating this type of living experience requires administrators understand the complexities of how housing can affect specific student groups and their decision to either persist at or leave an institution. This report explores the impact of housing and residence life at Utah State University on students living on campus. It disaggregates results …

Differences In Drought Tolerance Among Gisela® Cherry Rootstocks Determined Using Automated Weighing Lysimeters, Lance V. Stott, Brent Black, Bruce Bugbee

Plants, Soils, and Climate Faculty Publications

The Gisela® series of dwarfing rootstock are widely used because they enable high-density production, but they may be sensitive to drought. Drought tolerance may be associated with root-zone distribution and depth or with physiological adaptation to low water potential. Here we describe a novel technique for determining physiological tolerance to drought when root distribution is held constant. In two matching studies, we continuously measured transpiration of two groups of eight trees using a 16-container automated weighing lysimeter system in a greenhouse. With this system, Gisela® 3, 5, and 12 (G.3, G.5, and G.12) rootstocks were subjected to multiple, controlled drought …

Growth, Gas Exchange, And Mineral Nutrients Of Ornamental Grasses Irrigated With Saline Water, Yuxiang Wang, Youping Sun, Genhua Niu, Chaoyi Deng, Yi Wang, Jorge Gardea-Torresdey

Plants, Soils, and Climate Faculty Publications

Ornamental grasses are commonly used in urban landscapes in Utah and the Intermountain West of the United States. The relative salt tolerance of Eragrostis spectabilis (Pursh) Steud. (purple love grass), Miscanthus sinensis Andersson ‘Gracillimus’ (maiden grass), Panicum virgatum L. ‘Northwind’ (switchgrass), and Schizachyrium scoparium (Michx.) Nash (little bluestem) were evaluated in a greenhouse. Plants were irrigated with a nutrient solution at an electrical conductivity (EC) of 1.2 dS·m^–1 (control), or saline solution at an EC of 5.0 or 10.0 dS·m^–1. At harvest (65 days after the initiation of treatment), P. virgatum and S. scoparium exhibited no foliar …

Quantitative Trait Loci (Qtl) For Forage Traits In Intermediate Wheatgrass When Grown As Spaced-Plants Versus Monoculture And Polyculture Swards, John S. Mortenson, Blair L. Waldron, Steven R. Larson, Kevin B. Jensen, Lee R. Dehann, Michael D. Peel, Paul G. Johnson, J. Earl Creech

Plants, Soils, and Climate Faculty Publications

It has been hypothesized that the genetic control of forage traits, especially biomass, for grass plants growing as spaced-plants versus swards is different. Likewise, the genetic control of compatibility in grass–legume polyculture mixtures is assumed to be different than for forage production in a grass monoculture. However, these hypotheses are largely unvalidated, especially at the DNA level. This study used an intermediate wheatgrass mapping population to examine the effect of three competition environments (spaced-plants, polyculture, and monoculture) on classical quantitative genetic parameters and quantitative trait loci (QTL) identification for biomass, morphology, and forage nutritive value. Moderate to high heritable variation …

Effects Of Land-Use Change And Prey Abundance On The Body Condition Of An Obligate Carnivore At The Wildland-Urban Interface, Courtney A. C. Coon, Bradley C. Nichols, Zara Mcdonald, David C. Stoner

Wildland Resources Faculty Publications

Land-use change represents a primary driver of carnivore population declines, yet some large carnivore species have acclimated and persist within anthropogenically altered landscapes. Previous attention has been focused on the genetic and behavioral implications of land-use changes, but few studies have investigated how human development impacts animal physiology and health. Here we examined how body condition scores of a widely distributed North American carnivore, the puma (Puma concolor), are affected by anthropogenic habitat modification. For this study we collected 252 puma camera trap events across a land-use gradient in the San Francisco Bay Area. We found that pumas …

A Case For Eustress In Grazing Animals, Juan J. Villalba, Xavier Manteca

Wildland Resources Faculty Publications

Herbivores grazing in extensive systems are exposed to a series of challenges, rooted in the inherent spatial and temporal variability of their environment that potentially constrain their health, nutrition, and welfare. Nevertheless, in this review, we argue that challenges induced by some biotic (e.g., vegetation) and abiotic (e.g., terrain) factors may also be viewed as “positive” sources of stress or eustress, since they present complex problems, that when solved successfully elicit a greater degree of behavioral plasticity and adaptability in grazing animals. Chemically and structurally diverse landscapes require animals to display complex behaviors and exhibit adaptive capabilities, like building a …

Milk Oligopeptide Inhibition Of (Α)-Tocopherol Fortified Linoleic Acid Oxidation, Haina Yuan, Jinyan Gong, Kun Tang, Jinge Huang, Gongnian Xiao, Jianmin Lv

Biological Engineering Student Research

This study investigated the effect of milk oligopeptides and (α)-tocopherol on inhibition of linoleic acid oxidation using Fe²⁺-vitamin C induced linoleic acid oxidation model through analysis of malondialdehyde, peroxide value, and conjugated diene and triene in the model. The alteration of milk oligopeptides maximal absorption wavelength, fluorescent feature, and secondary structure were further investigated to elucidate the interactions between milk oligopeptide and (α)-tocopherol that altered the inhibitory effect of linoleic acid oxidation. Results showed that Pro-Tyr-Tyr-Ala-Lys (PYYAK) and Ile-Pro-Ile-Gln-Tyr (IPIQY) with (α)-tocopherol significantly inhibited the oxidation of linoleic acid and reduced the formation of malondialdehyde by 38% and …

Tannin-Containing Legumes And Forage Diversity Influence Foraging Behavior, Diet Digestibility, And Nitrogen Excretion By Lambs, Sebastian Lagrange, Juan J. Villalba

Wildland Resources Faculty Publications

Diverse combinations of forages with different nutrient profiles and plant secondary compounds may improve intake and nutrient utilization by ruminants. We tested the influence of diverse dietary combinations of tannin- (sainfoin-Onobrichis viciifolia; birdsfoot trefoil-Lotus corniculatus) and non-tannin- (alfalfa-Medicago sativa L.) containing legumes on intake and diet digestibility in lambs. Freshly cut birdsfoot trefoil, alfalfa, and sainfoin were offered in ad libitum amounts to 42 lambs in individual pens assigned to 7 treatments (6 animals/treatment): 1) single forage species (sainfoin [SF], birdsfoot trefoil [BFT], and alfalfa [ALF]), 2) all possible …

A Review And Updated Classification Of Pollen Gathering Behavior In Bees (Hymenoptera, Apoidea), Zachary M. Portman, Michael C. Orr, Terry Griswold

All PIRU Publications

Pollen is the primary protein and nutrient source for bees and they employ many different behaviors to gather it. Numerous terms have been coined to describe pollen gathering behaviors, creating confusion as many are not clearly-defined or overlap with existing terms. There is a need for a clear yet flexible classification that enables accurate, succinct descriptions of pollen gathering behaviors to enable meaningful discussion and comparison. Here, we classify the different pollen gathering behaviors into two main classes: active and incidental pollen collection. Active pollen collection is subdivided into six behaviors: scraping with the extremities, buzzing, rubbing with the body …

Phylogeny Of The Subfamilies Of Ichneumonidae (Hymenoptera), Andrew M.R. Bennett, Sophie Cardinal, Ian D. Gauld, David B. Wahl

Biology Faculty Publications

A combined morphological and molecular phylogenetic analysis was performed to evaluate the subfamily relationships of the parasitoid wasp family Ichneumonidae (Hymenoptera). Data were obtained by coding 135 morphological and 6 biological characters for 131 exemplar species of ichneumonids and 3 species of Braconidae (the latter as outgroups). The species of ichneumonids represent all of the 42 currently recognized subfamilies. In addition, molecular sequence data (cytochrome oxidase I “DNA barcoding” region, the D2 region of 28S rDNA and part of the F2 copy of elongation factor 1-alpha) were obtained from specimens of the same species that were coded for morphology (1309 …

Effectiveness Of Three Foodservice Equipment Training Interventions For Food And Nutrition Students, Tiffan C. Frieson, Katie R. Miner, Robert Haggerty, Katie Nicole Brown

Nutrition, Dietetics, and Food Sciences Faculty Publications

This study evaluated students’ (N = 65) reported knowledge, competence, and comfort in using foodservice equipment, as well as confidence in training others after completing one of the following interventions: 1) two food/nutrition courses, and foodservice supervised practice rotations, 2) equipment introduction, and competency exam, and 3) equipment training, practice lab, and competency exam. Foodservice operations and dietetics programs should consider implementing Intervention 3 because there was a significant increase in knowledge, competence, comfort, and confidence using equipment from pre- to post-intervention, it yielded the highest post-intervention scores, and most students received >86% for their actual skill.

The Missing Angle: Ecosystem Consequences Of Phenological Mismatch, Karen H. Beard, Katharine C. Kelsey, A. Joshua Leffler, Jeffrey M. Welker

Ecology Center Publications

Climate change leads to unequal shifts in the phenology of interacting species, such as consumers and their resources, leading to potential phenological mismatches. While studies have investigated how phenological mismatch affects wild populations, we still lack studies and a framework for investigating how phenological mismatch affects ecosystems, particularly nutrient cycling.

Environmental Differences Between Migratory And Resident Ungulates—Predicting Movement Strategies In Rocky Mountain Mule Deer (Odocoileus Hemionus) With Remotely Sensed Plant Phenology, Snow, And Land Cover, Benjamin Robb, Qiongyu Huang, Joseph O. Sexton, David C. Stoner, Peter Leimgruber

Wildland Resources Faculty Publications

Migration is a valuable life history strategy for many species because it enables individuals to exploit spatially and temporally variable resources. Globally, the prevalence of species’ migratory behavior is decreasing as individuals forgo migration to remain resident year-round, an effect hypothesized to result from anthropogenic changes to landscape dynamics. Efforts to conserve and restore migrations require an understanding of the ecological characteristics driving the behavioral tradeoff between migration and residence. We identified migratory and resident behaviors of 42 mule deer (Odocoileus hemionus) based on GPS locations and correlated their locations to remotely sensed indicators of forage quality, land cover, snow …

Integration Of Science, Technology, Engineering, And Math Into A Food And Nutrition Curriculum In Utah, Cathy A. Merrill, Becki G. Lawver

Applied Sciences, Technology and Education Faculty Publications

In 2014, Family and Consumer Sciences teachers in Utah revised the Food and Nutrition Sciences curriculum to strengthen Science, Technology, Engineering, and Math (STEM)‐related content. This study is a needs assessment of the state implementation of the STEM‐enhanced curriculum in 2015–2016. A Borich needs assessment model was used to analyze mean weighted discrepancy scores between teacher‐perceived levels of importance and teacher‐perceived competence for each objective in the new curriculum. The results showed that although teachers felt moderately competent to teach the new curriculum, the highest ranked need for professional development was in Standard 1: Kitchen Safety Procedures and Sanitation. Professional …

Synthesis Paper: Targeted Livestock Grazing: Prescription For Healthy Rangelands, Derek W. Bailey, Jeffrey C. Mosley, Richard E. Estell, Andres F. Cibils, Marc Horney, John R. Hendrickson, John W. Walker, Karen L. Launchbaugh, Elizabeth A. Burritt

Wildland Resources Faculty Publications

Targeted livestock grazing is a proven tool for manipulating rangeland vegetation, and current knowledge about targeted livestock grazing is extensive and expanding rapidly. Targeted grazing prescriptions optimize the timing, frequency, intensity, and selectivity of grazing (or browsing) in combinations that purposely exert grazing/browsing pressure on specific plant species or portions of the landscape. Targeted grazing differs from traditional grazing management in that the goal of targeted grazing is to apply defoliation or trampling to achieve specific vegetation management objectives, whereas the goal of traditional livestock grazing management is generally the production of livestock commodities. A shared aim of targeted livestock …

“How Long Must We Wait?” Lessons From The History Of The Animal Welfare Movement, Rachel Robinson-Greene

Languages, Philosophy, and Communication Studies Faculty Publications

In a series of boxes in the D.H. Hill Library at North Carolina State sit scores of historical pamphlets and newspaper articles advocating an end to cruelty toward animals. The documents date back to the nineteenth century, and provide an undeniable record of the history of strong public sentiment against the mistreatment of animals. The collection preserves the stories of countless activists who opposed inhumane treatment in slaughterhouses, research labs, the entertainment industry, transport, and sport, among other endeavors. These activists dedicated inspiring amounts of time, energy, and resources to a cause that is seldom given the attention that it …
