Understanding Free-Roaming Horse Conflicts With Wildlife In The Great Basin, S. Nicole Frey, Eric Thacker, Katlyn Uhart

All Current Publications

Horses and burros were introduced to North America in the 1600s with European missionaries and explorers. Over time, abandoned and released horses and burros formed herds and by the time European-American settlers began to explore North America in the 1700s, these free-roaming horses and burros had adapted to their habitat and been incorporated into Native American culture. By the mid-1900s, most Americans considered these horses as wild and symbols of freedom and beauty.

In 1971, Congress passed the Wild and Free-Roaming Horses and Burros Act (Public Law 73-482) to provide federal protection for free-roaming horses and burros (also known as …

Interrater Reliability Of Novice Examiners Using A-Mode Ultrasound And Skinfolds To Measure Subcutaneous Body Fat, Dale R. Wagner, Masaru Teramoto

Kinesiology and Health Science Faculty Publications

Examiners with minimal training and skill are often called upon to make body composition assessments using field methods. This study compared the interrater reliability of novice examiners for the skinfold (SKF) and A-mode ultrasound (US) methods of body composition assessment. Undergraduate Kinesiology majors (48 males, 32 females) with minimal training took both SKF and US measurements at three sites (males: chest, abdomen, thigh; females: triceps, suprailiac, thigh). Interrater reliability was significantly better for US compared to SKF at the thigh (ICC_US = 0.975, ICC_SKF = 0.912) and abdomen (ICC_US = 0.984, ICC_SKF = 0.693) for men …

Watering The Landscape: Make It Easier With Evapotranspiration (Et), Candace Schaible, Kelly Kopp, Helen Muntz

All Current Publications

The American lawn is our nation’s single largest irrigated “crop” (Lindsey, 2005). In Utah, roughly 65% of our drinking water is applied to residential and commercial landscapes (Center for Water Efficient Landscaping, 2020). Landscapes are typically overwatered, which is why residential and commercial landscape watering is estimated to be one of the largest sources of potential water conservation in the urban setting (Endter-Wada et al., 2008). Plant materials also provide many environmental benefits, such as erosion control, water filtration, and temperature reduction. Knowing how much water to apply to the landscape can be a challenge and is one reason many …

Watershed Sciences Faculty Publications

While the importance of reducing impacts of non-native species is increasingly recognized in conservation, the feasibility of such actions is highly dependent upon several key uncertainties including stage of invasion, size of the ecosystem being restored, and magnitude of the restoration activity. Here, we present results of a multi-year, non-native brown trout (Salmo trutta) removal and native Bonneville cutthroat trout (Oncorhynchus clarkii utah) response to this removal in a small tributary in the Intermountain West, United States. We monitored trout for 10 years prior to the onset of eradication efforts, which included 2 years of mechanical …

Understanding Caffeine Vs. Kids, Cindy Nelson, Rachel Mcmaster

All Current Publications

Children enjoy numerous foods and drinks on a regular basis that contain caffeine: soda, chocolate candy, energy drinks, and so forth. In fact, almost 3 out of 4 children consume caffeine regularly (American Academy of Family Physicians, 2020). This is a concern because studies show caffeine can affect children and adults differently, and too much caffeine can have detrimental health effects on kids. This fact sheet defines caffeine, reviews its effects and risks, identifies popular foods containing caffeine, and how to reduce consumption of caffeine.

Aspen Soils Retain More Dissolved Organic Carbon Than Conifer Soils In A Sorption Experiment, Antra Boča, Astrid R. Jacobson, Helga Van Miegroet

Aspen Bibliography

The effect tree species have on soil organic carbon (SOC) has been hotly debated but, so far, few clear patterns have emerged. One example of a differing tree species effect on SOC are aspen forests in North America, which have been found to have more stable SOC than adjacent conifer forest stands. An important source for the formation of stable organo-mineral complexes in soil is dissolved organic carbon (DOC). DOC concentrations in mineral soil are often higher under the thick O-horizons of conifer forests than under aspen forests, but this does not correspond to more stable mineral SOC. This suggests …

Sustaining Wildlife With Recreation On Public Lands: A Synthesis Of Research Findings, Management Practices, And Research Needs, Anna B. Miller, David King, Mary Rowland, Joshua Chapman, Monica Tomosy, Christina Liang, Eric S. Abelson, Richard L. Truex

All Publications

Humans and wildlife interact in multifaceted ways on public lands with both positive and negative outcomes for each group. When managed well, wildlife-based tourism and other forms of recreation can benefit conservation goals. Public lands planners and managers often must decide how to best manage recreational activities and wildlife habitats that overlap spatially and temporally. We conducted an extensive literature review and categorized recreational activity into five types based on the use of motorized equipment, season, and location (terrestrial vs. aquatic), expanding on findings summarized in prior reviews. Our findings provide a reference for public lands planners and managers who …

Three-Lined Potato Beetle, Nick Volesky

All Current Publications

The three-lined potato beetle (Lema daturaphila) is part of the Chrysomelidae family of beetles. It originates from North and Central America but has since been reported causing economic damage to crops worldwide, such as the cape gooseberry in South Africa and potato in Australia. Though uncommon, the three-lined potato beetle has previously been documented in Utah. In August 2020, it was closely observed causing economic damage in tomatillo production on a commercial vegetable farm in rural Box Elder County, Utah. This fact sheet reviews three-lined potato beetle identification, life cycle, and look-alikes, damage, and management.

Row Covers, Nick Volesky, Katherine Wagner

All Current Publications

In agricultural use, a row cover is a transparent or semitransparent material that is used over crops (typically vegetables) for a variety of purposes. As an integrated pest management tool, row covers act as a physical barrier that prevents the movement of pests such as insects, birds, and mammals, to host plants. This form of management is popular in organic production to avoid chemical application. Row covers are also used to shield crops from environmental factors like cold or hot temperatures, and wind. Commonly used methods of application include floating row covers, hoop-supported row covers (also called low tunnels), and …

Selecting Summer-Bearing Raspberry Cultivars For Northern Utah, Sheriden M. Hansen, Brent Black, Diane G. Alston, Tiffany Maughan, Rick Hefelbower

All Current Publications

Summer-bearing raspberry plants are typically well-suited to Utah as they bloom and bear fruit during mid-summer, allowing plants to reach their full yield potential before the first fall freeze. Important characteristics to consider in selecting summer-bearing cultivars are winter hardiness, yield, and fruit quality, including sunburn resistance and resistance to common insects and diseases. This fact sheet discusses two different research trials that were conducted from 2008 to 2015 in Kaysville, Utah to evaluate the suitability of twenty-one different summer-bearing cultivars to northern Utah.

Plant Single-Cell Metabolomics—Challenges And Perspectives, Leonardo Perez De Souza, Monica Borghi, Alisdair R. Fernie

Biology Faculty Publications

Omics approaches for investigating biological systems were introduced in the mid-1990s and quickly consolidated to become a fundamental pillar of modern biology. The idea of measuring the whole complement of genes, transcripts, proteins, and metabolites has since become widespread and routinely adopted in the pursuit of an infinity of scientific questions. Incremental improvements over technical aspects such as sampling, sensitivity, cost, and throughput pushed even further the boundaries of what these techniques can achieve. In this context, single-cell genomics and transcriptomics quickly became a well-established tool to answer fundamental questions challenging to assess at a whole tissue level. Following a …

Managing Suckers Around Fruit Trees, Samuel Johnson, Teryl Roper, Xin Dai

All Current Publications

Many types of fruit trees produce suckers around the base of the tree. Crown suckers arise in the area immediately surrounding the tree trunk (Photo 1), and root suckers can arise from roots further away from the trunk. Not only are suckers around trees unsightly, but they can also harbor insect pests like wooly apple aphid and provide points of entry for diseases like fire blight. If suckers are profuse, they interfere with in-row weed management and can absorb systemic herbicides such as glyphosate. Some rootstocks used for fruit trees such as M.7 for apples and Mazzard for cherries are …

Biology Faculty Publications

Permafrost degradation is delivering bioavailable dissolved organic matter (DOM) and inorganic nutrients to surface water networks. While these permafrost subsidies represent a small portion of total fluvial DOM and nutrient fluxes, they could influence food webs and net ecosystem carbon balance via priming or nutrient effects that destabilize background DOM. We investigated how addition of biolabile carbon (acetate) and inorganic nutrients (nitrogen and phosphorus) affected DOM decomposition with 28-day incubations. We incubated late-summer stream water from 23 locations nested in seven northern or high-altitude regions in Asia, Europe, and North America. DOM loss ranged from 3% to 52%, showing a …

Environment and Society Faculty Publications

Although natural resource managers are concerned about climate change, many are unable to adequately incorporate climate change science into their adaptation strategies or management plans, and are not always aware of or do not always employ the most current scientific knowledge. One of the most prominent natural resource management agencies in the United States is the Bureau of Land Management (BLM), which is tasked with managing over 248 million acres (>1 million km²) of public lands for multiple, often conflicting, uses. Climate change will affect the sustainability of many of these land uses and could further increase …

Increasing Our Ability To Predict Contemporary Evolution, Patrik Nosil, Samuel M. Flaxman, Jeffrey L. Feder, Zachariah Gompert

Biology Faculty Publications

Classic debates concerning the extent to which scientists can predict evolution have gained new urgency as environmental changes force species to adapt or risk extinction. We highlight how our ability to predict evolution can be constrained by data limitations that cause poor understanding of deterministic natural selection. We then emphasize how such data limits can be reduced with feasible empirical effort involving a combination of approaches.

Preventing Allergies In Infants: What Foods To Introduce And When, Annika Israelsen, Stacy Bevan, Mateja R. Savoie-Roskos

All Current Publications

Food allergies have become increasingly common over the past several years among children in the United States (Comberiati et al., 2019; Sicherer et al., 2017). Food allergies are a negative immune response occurring in the body after eating a specific food (Sicherer et al., 2017). Unlike food intolerances, such as lactose intolerance which causes uncomfortable symptoms in the stomach and intestines, allergic reactions to food can cause a wide range of serious and sometimes fatal symptoms (Konek & Becker, 2020). Food allergies can affect a child’s health and quality of life, while also impacting their caregivers’ lives (Sicherer et al., …
