A Novel Method For Detecting Wild Boar Presence, Giovanna Massei, Dave P. Cowan, Julia Coats

Human–Wildlife Interactions

Populations of wild boar and feral pigs (Sus scrofa) are increasing in numbers and distribution worldwide, in parallel with their significant environmental and economic impact. Reliable methods to detect the presence of this species are needed for monitoring its natural range expansion and its occurrence in areas where animals have been deliberately or accidentally introduced. The main aim of this study, carried out in English woodlands recently colonized by wild boar, was to assess the effectiveness of a birch wood tar-based compound, to detect the presence of this species in presence/absence surveys. A pilot trial in woodlands where …

Reduced Fecundity In Free-Ranging Norway Rats After Baiting With A Liquid Fertility Control Bait, Gary W. Witmer, Stefanie Raymond-Whish

Human–Wildlife Interactions

Norway rats (Rattus norvegicus) cause extensive crop loss, infrastructure damage, and are vectors for zoonotic diseases. Due to reduced efficacy, environmental and animal welfare concerns related to traditional pest management tools, such as rodenticides, it is imperative to find new methods for controlling commensal rodents. Fertility control is emerging as a safe, humane, and effective method of long-term population management. Vinylcyclohexene diepoxide (VCD) and triptolide are 2 compounds that are known to target and inhibit ovarian function. Furthermore, triptolide debilitates spermatogenesis and sperm motility. We prepared liquid bait containing no active ingredients (control) or containing VCD (0.098%) and …

Review: Closing Nutrient Cycles For Animal Production – Current And Future Agroecological And Socio-Economic Issues, S. L. Kronberg, F. D. Provenza, S. Van Vliet, Sierra N. Young

Civil and Environmental Engineering Faculty Publications

We face an urgent and complex challenge to produce large amounts of healthful animal and plant foods for an estimated 10 billion people by 2050 while maintaining essential ecosystem services. To compound this challenge, we must do so while not further degrading our environment and conserving essential nutrients such as copper, magnesium, phosphorus, selenium, and zinc that are in short supply for fertilization. Much good research has been done, but to meet this challenge, we need to greatly increase on-farm and watershed-scale research including on-farm evaluations and demonstrations of the putative best combinations of stewardship techniques over multiple years in …

Cranial Cruciate Ligament Desmotomies In Sheep Resulting In Peroneus Tertius Injury, Peter J. Welsh, Crystal G. Collier, Holly M. Clement, Michael N. Vakula, Jeffrey B. Mason

Animal, Dairy, and Veterinary Science Student Research

Surgical destabilization of the stifle joint via cranial cruciate ligament desmotomy (CCLD) is a routine procedure for the study of osteoarthritis (OA). Traditionally performed in rats, rabbits, cats, and dogs, CCLD in sheep provides an opportunity to study the pathology and treatment of joint instability in a species whose stifle better represents the equivalent human femorotibial joint. The surgical approaches for CCLD in sheep are variable and can result in inconsistent outcomes. Eight sheep underwent CCLD for use in a gene therapy study. We report this case in which six of the eight sheep were clinically diagnosed by pathognomonic signs …

Book Review: The Wildlife Techniques Manual, Eighth Edition, Justin Small

Human–Wildlife Interactions

Wildlife researchers and managers are consistently tackling ecological and conservation issues that are increasing in complexity and scope. Wildlife issues often span beyond singular research frameworks and management jurisdictions, preventing modern wildlife conservation from operating in mutually exclusive arenas (i.e., research or management). As a wildlife researcher whose research is conducted on both public and private rangelands, and across multiple stakeholder groups, techniques to answer difficult questions and offer time-sensitive solutions must pull from both research and management arenas. Historically, book or journal resources that wildlife professionals could readily access for necessary scientific guidance were contained in many documents, making …

Evaluation Of Damage To Forest Tree Plantations By Wild Boar In The Czech Republic, Vlastimil Skoták, Jakub Drimaj, Jiří Kamler

Human–Wildlife Interactions

Wild boar (Sus scrofa) populations in Central Europe have been growing long-term, and damages to crops and forests where boars damage freshly planted tree seedlings are growing too. In addition to having a significant economic impact, these damages worsen the prospect of successful restoration of bare land. This study presents an analysis of damage to tree seedling plantations caused by wild boar in the Czech Republic. We used data from an extensive questionnaire survey among forest owners, our own survey of the extent of damage in model areas, and experiments in locations with a large boar population. Damage …

Utility Of Visual Counts For Determining Efficacy Of Management Tools For California Ground Squirrels, Roger A. Baldwin, Theresa A. Becchetti, Niamh Quinn, Ryan Meinerz

Human–Wildlife Interactions

Visual counts are frequently used to assess efficacy of management tools for ground squirrels (Marmotini), but the effectiveness of this approach has not been assessed for many ground squirrel species including California ground squirrels (Otospermophilus spp.). As such, we used visual counts of California ground squirrels to determine the efficacy of diphacinone-treated oat groat applications in rangelands in central California, USA, and compared those results to efficacy values derived from the use of radio-collared ground squirrels in the same plots. We also used location data of radio-collared ground squirrels to explore the size of buffer zone needed around census …

Characteristics Of Non-Fatal Attacks By Black Bears: Conterminous United States, 2000–2017, Janel M. Scharhag, Cady Sartini, Shawn M. Crimmins, Scott E. Hygnstrom, Jeffrey B. Stetz

Human–Wildlife Interactions

Attacks on humans by bears (Ursus spp.) have increased in recent decades, as both human and bear populations have increased. To help mitigate the risk of future attacks, it is important to understand the circumstances in past attacks. Information and analyses exist regarding fatal attacks by both American black bears (Ursus americanus) and brown bears (U. arctos) as well as non-fatal attacks by brown bears. No similarly thorough analyses on non-fatal attacks by black bears are available. Our study addressed this information gap by analyzing all (n = 210) agency-confirmed, non-fatal attacks by black …

What Is Biochar And How Is It Used?, Marion Murray

All Current Publications

Biochar is a charcoal-like product that contains no petroleum. It is made by heating biomass such as herbaceous or woody crop residues, non-salvageable timber, and slash, or animal manure, in a contained system. There are many potential uses for biochar including water treatment, land reclamation, and carbon sequestration. Biochar may also be used as a soil amendment for two purposes – to improve plant health and to store carbon.

Features Of Direct Instruction: Content Analysis, Timothy A. Slocum, Kristen R. Rolf

Special Education and Rehabilitation Counseling Faculty Publications

The goal of Direct Instruction (DI) is to teach content as effectively and efficiently as possible. To do this, instructional designers must identify generative relations or strategies that allow the learner to respond correctly to untaught situations. The purpose of content analysis is to identify generative relations in the domain to be taught and arrange the content in such a way that it supports maximally generative instruction. This article explains the role of content analysis in developing DI programs and provides examples and nonexamples of content analysis in five content domains: spelling, basic arithmetic facts, earth science, basic language, and …

Landscape-Scale Drivers Of Resistance And Resilience To Bark Beetles: A Conceptual Susceptibility Model, Marcella A. Windmuller-Campione, R. Justin Derose, James N. Long

Wildland Resources Faculty Publications

Bark beetle (Dendroctonus spp.) outbreaks in the middle latitudes of western North America cause large amounts of tree mortality, outstripping wildfire by an order of magnitude. While temperatures play an important, and direct role in the population dynamics of ectothermic bark beetles, an equally important influence is the nature of the host substrate—the structure and composition of forested communities. For many of the dominant tree species in the western United States, “hazard” indices have been developed for specific bark beetles, which generally include three key variables—host tree size, absolute or relative density of the stand, and percentage of host composition. …

Changing Land Use And Population Density Are Degrading Water Quality In The Lower Mekong Basin, Flavia Tromboni, Thomas E. Dilts, Sarah E. Null, Sapana Lohani, Peng Bun Ngor, Savoeurn Soum, Zeb Hogan, Sudeep Chandra

Watershed Sciences Faculty Publications

Establishing reference conditions in rivers is important to understand environmental change and protect ecosystem integrity. Ranked third globally for fish biodiversity, the Mekong River has the world’s largest inland fishery providing livelihoods, food security, and protein to the local population. It is therefore of paramount importance to maintain the water quality and biotic integrity of this ecosystem. We analyzed land use impacts on water quality constituents (TSS, TN, TP, DO, NO3−, NH4+, PO43−) in the Lower Mekong Basin. We then used a best‐model regression approach with anthropogenic land‐use as independent variables and water quality parameters as the dependent variables, to …

Enhancing Existing Isolated Underpasses With Fencing Reduces Wildlife Crashes And Connects Habitat, Bridget M. Donaldson, Kaitlyn E. M. Elliott

Human–Wildlife Interactions

The impact of wildlife–vehicle collisions on drivers and wildlife populations has been gaining attention in the United States. Given the established success of wildlife crossings with fencing in reducing wildlife crashes and connecting habitat, information is needed on cost-effective means of implementation for departments of transportation. When wildlife crossings are constructed, they are often built into new road projects as a series of 2 or more underpasses and/or overpass structures connected by exclusionary fencing. Given limited transportation budgets and the prevalence of maintenance activities more so than new construction in many states, enhancing existing underpasses on previously constructed roads has …

Temporal Trends And Drivers Of Mountain Lion Depredation In California, Usa, Justin A. Dellinger, Daniel K. Macon, Jaime L. Rudd, Deana L. Clifford, Steven G. Torres

Human–Wildlife Interactions

Increasing human populations and expanding development across the globe necessitate continual progress in understanding and mitigating human–wildlife conflict. California, USA has the largest human population and at least half of the state is suitable mountain lion (Puma concolor) habitat. The juxtaposition of high human abundance within and adjacent to mountain lion habitat make California relevant for understanding human–large carnivore conflict. We compiled 7,719 confirmed incidents of mountain lions depredating domestic animals over a 48-year period (1972–2019) to examine temporal trends in mountain lion depredations as well as factors influencing annual depredation rates at the county level. Linear regressions …

Association And Agreement Between Reactive Strength Index And Reactive Strength Index-Modified Scores, Talin Louder, Brennan J. Thompson, Eadric Bressel

Kinesiology and Health Science Faculty Publications

Since the reactive strength index (RSI) and reactive strength index-modified (RSI-mod) share similar nomenclature, they are commonly referred as interchangeable measures of agility in the sports research literature. The RSI and RSI-mod are most commonly derived from the performance of depth jumping (DJ) and countermovement jumping (CMJ), respectively. Given that DJ and CMJ are plyometric movements that differ materially from biomechanical and neuromotor perspectives, it is likely that the RSI and RSI-mod measure distinct aspects of neuromuscular function. The purpose of this investigation was to evaluate the association and agreement between RSI and RSI-mod scores. A mixed-sex sample of NCAA …

Sheep Models Of F508del And G542x Cystic Fibrosis Mutations Show Cellular Responses To Human Therapeutics, Iuri Viótti Périssé, Zhiqiang Fan, Arnaud J. Van Wettere, Ying Liu, Shih-Hsing Leir, Jacob Keim, Misha Regouski, Michael D. Wilson, Kelly M. Cholewa, Sara N. Mansback, Thomas J. Kelly, Zhongde Wang, Ann Harris, Kenneth L. White, Irina A. Polejaeva

Animal, Dairy, and Veterinary Science Student Research

Cystic Fibrosis (CF) is a genetic disease caused by mutations in the CF transmembrane conductance regulator (CFTR) gene. The F508del and G542X are the most common mutations found in US patients, accounting for 86.4% and 4.6% of all mutations, respectively. The F508del causes deletion of the phenylalanine residue at position 508 and is associated with impaired CFTR protein folding. The G542X is a nonsense mutation that introduces a stop codon into the mRNA, thus preventing normal CFTR protein synthesis. Here, we describe the generation of CFTRF^{508del/F508del} and CFTR^G542X/G542X lambs using CRISPR/Cas9 and …

Psychology Faculty Publications

Aims

To determine whether an educational programme targeting the reaction of veterinary personnel to difficult client interactions reduced burden transfer, stress and burnout in veterinary staff.

Methods

Employees of three small-animal veterinary hospitals in the south-western United States of America were recruited and randomised to intervention (educational programme; n = 16) or control (no intervention; n = 18) groups. Participants of this randomised, parallel arms trial completed pre-programme assessment including the Burden Transfer Inventory (BTI), Perceived Stress Scale, and Copenhagen Burnout Inventory. Assessment was followed by two, group-format educational sessions, based on acceptance and commitment training, tailored to reducing reactivity …

An Open Web-Based Module Developed To Advance Data-Driven Hydrologic Process Learning, Belize A. Lane, Irene Garousi-Nejad, Melissa A. Gallagher, David G. Tarboton, Emad Habib

Civil and Environmental Engineering Faculty Publications

The era of ‘big data’ promises to provide new hydrologic insights, and open web-based platforms are being developed and adopted by the hydrologic science community to harness these datasets and data services. This shift accompanies advances in hydrology education and the growth of web-based hydrology learning modules, but their capacity to utilize emerging open platforms and data services to enhance student learning through data-driven activities remains largely untapped. Given that generic equations may not easily translate into local or regional solutions, teaching students to explore how well models or equations work in particular settings or to answer specific problems using …

Identification And Management Of Scotch Thistle (Onopordum Acanthium L.) In Pastures, Rangelands, And Non-Crop Settings, Cody Zesiger, Jacob Hadfield, Kalen Taylor, Corey Ransom

All Current Publications

Scotch thistle (Onopordum acanthium) is an invasive species native to Eurasia. It was likely introduced into North America during the late 19th century (Young & Evans, 1969). Due to the plant’s size and prickles, a stand can damage pasture productivity, ruin campsites, or make trails nearly impassable. The thistle also outcompetes desirable plants and greatly reduces forage use by large animals. Since not all thistles are related or alike, it is essential to correctly identify Scotch thistle before making management decisions. This fact sheet provides information about identification, lifecycle and distribution, and management.

Identifying And Managing Dyer's Woad (Isatis Tinctoria) In Pastures, Rangelands, And Non-Crop Settings, Cody Zesiger, Jacob Hadfield, Corey Ransom

All Current Publications

Dyer's woad (Isatis tinctoria) was introduced into Utah during the mid-nineteenth century as a source of indigo dye. The plant escaped cultivation and has spread across rangelands, foothills, and other sites throughout the Intermountain West. This fact sheet provides information about identifying dyer's woad and its lifecycle, distribution, and management in pastures, rangelands, and non-crop settings. It includes information about using appropriate herbicides to control dyer's woad and how to apply them.

The Ethics Of Animal Dis-Enhancement., Rachel Robinson-Greene

Languages, Philosophy, and Communication Studies Faculty Publications

Human beings have long treated animals not as sentient beings, but as objects or products to be used and consumed. We do this in spite of the fact that animals demonstrate every sign of having mental lives. We have the same reasons to believe that animals have mental lives that we do to believe that other human beings have mental lives; the best evidence we have is behavior. Humans report having affection for animals. Nevertheless, we intensively farm them for food and use them for medical experiments, activities which are quite painful and lead to suffering, permanent disability, and/or death. …

Fruits, Frugivores, And The Evolution Of Phytochemical Diversity, Susan R. Whitehead, Gerald F. Schneider, Ray Dybzinski, Annika S. Nelson, Mariana Gelambi, Elsa Jos, Noelle G. Beckman

Biology Faculty Publications

Plants produce an enormous diversity of secondary metabolites, but the evolutionary mechanisms that maintain this diversity are still unclear. The interaction diversity hypothesis suggests that complex chemical phenotypes are maintained because different metabolites benefit plants in different pairwise interactions with a diversity of other organisms. In this synthesis, we extend the interaction diversity hypothesis to consider that fruits, as potential hotspots of interactions with both antagonists and mutualists, are likely important incubators of phytochemical diversity. We provide a case study focused on the Neotropical shrub Piper reticulatum that demonstrates: 1) secondary metabolites in fruits have complex and cascading effects for …

Farmers Feeding Utah: Increasing Healthy Food Access And Supporting Local Agriculture, Heidi Leblanc, Casey Coombs

Outcomes and Impact Quarterly

The need for food assistance increased by 300% among Utah families as a result of the COVID-19 pandemic. Farmers and ranchers were also adversely impacted by market losses and processing shortages. In response, Farmers Feeding Utah was developed to facilitate access to fresh agricultural produce for families in need.

Decision-Making For Rewilding: An Adaptive Governance Framework For Social-Ecological Complexity, James R. A. Butler, Mariella Marzano, Nathalie Pettorelli, Sarah M. Durant, Johan T. Du Toit, Juliette C. Young

Wildland Resources Faculty Publications

Rewilding can be defined as the reorganisation or regeneration of wildness in an ecologically degraded landscape with minimal ongoing intervention. While proposals for rewilding are increasingly common, they are frequently controversial and divisive amongst stakeholders. If implemented, rewilding initiatives may alter the social-ecological systems within which they are situated and thus generate sudden and unforeseen outcomes. So far, however, much of the discourse on the planning and implementation of rewilding has focused on identifying and mitigating ecological risks. There has been little consideration of how rewilding could alter the human components of the social-ecological systems concerned, nor governance arrangements that …

Community Supported Agriculture: Accepting Snap Payments, Kelsey Hall, Roslynn Mccann

All Current Publications

Participating in a community supported agriculture (CSA) share is one way for individuals with low income to use their Supplemental Nutrition Assistance Program (SNAP) benefits in buying local, seasonal fruits and vegetables. The U.S. Department of Agriculture’s Food and Nutrition Service (USDA FNS) authorizes businesses to accept SNAP benefits, including direct marketing farmers and nonprofit food buying cooperatives operating a CSA. SNAP is the largest federal nutrition assistance program, formerly known as food stamps. Eligible individuals and families use an Electronic Benefit Transfer (EBT) card, similar to a debit card, to purchase eligible food at SNAP authorized vendors. In Utah, …

Trophic Niches Of Native And Nonnative Fishes Along A River-Reservoir Continuum, Casey A. Pennock, Zachary T. Ahrens, Mark C. Mckinstry, Phaedra Budy, Keith B. Gido

Watershed Sciences Faculty Publications

Instream barriers can constrain dispersal of nonnative fishes, creating opportunities to test their impact on native communities above and below these barriers. Deposition of sediments in a river inflow to Lake Powell, USA resulted in creation of a large waterfall prohibiting upstream movement of fishes from the reservoir allowing us to evaluate the trophic niche of fishes above and below this barrier. We expected niche overlap among native and nonnative species would increase in local assemblages downstream of the barrier where nonnative fish diversity and abundance were higher. Fishes upstream of the barrier had more distinct isotopic niches and species …

Chapter 4- Advancing An Approach Of Resilient Design For Learning By Designing For Extensibility, Flexibility, And Redundancy, Rebecca M. Quintana, Jacob Fortman, James Devaney

Resilient Pedagogy

The impact of the COVID-19 crisis on educational systems requires actors across those systems to develop adaptive capacity and embed resilient thinking into approaches and frameworks for decision-making and design (DeVaney & Quintana, 2020). Events surrounding the COVID-19 crisis have set off a period of rapid adaptation across the higher-education ecosystem and have necessitated that educators consider new pedagogical approaches and frameworks that are responsive to the changes we are witnessing in our contexts of teaching and learning (Chraa et al., 2020; Donovan, 2020; Moorhouse, 2020; Quintana & Quintana, 2020; Zhu & Liu, 2020).

Chapter 8- Creating Adaptable Courses: A Course Design Approach That Accommodates Flexible Delivery, Kosta Popovic, Eric M. Reyes, Jennifer B. O'Connor, Kay C. Dee, Ella Ingram

Resilient Pedagogy

In early 2020, educators and students around the world endured lapses in quality of educational experiences due to the disruption caused by COVID-19. In return for these lapses, students continued their programs of study within previously established timelines, and educators balanced helping students achieve learning objectives while keeping a manageable workload. Moving forward, students will expect educators and their institutions to deliver high-quality education when disruptions occur, like natural disasters, facilities emergencies, or supply chain disturbances. This expectation will extend to all modes of delivery. We assert that training educators to build adaptable courses that provide them and their students …

Drivers Of Fatal Bird Collisions In An Urban Center, Benjamin M. Van Doren, David E. Willard, Mary Hennen, Kyle G. Horton, Erica F. Stuber, Daniel Sheldon, Ashwin H. Sivakumar, Julia Wang, Andrew Farnsworth, Benjamin M. Winger

Wildland Resources Faculty Publications

Millions of nocturnally migrating birds die each year from collisions with built structures, especially brightly illuminated buildings and communication towers. Reducing this source of mortality requires knowledge of important behavioral, meteorological, and anthropogenic factors, yet we lack an understanding of the interacting roles of migration, artificial lighting, and weather conditions in causing fatal bird collisions. Using two decades of collision surveys and concurrent weather and migration measures, we model numbers of collisions occurring at a large urban building in Chicago. We find that the magnitude of nocturnal bird migration, building light output, and wind conditions are the most important predictors …
