Weed Incursion Of Irrigated Forage–Forb Mixtures Under Mob Grazing Or Mowing In The Mountain West Usa, Jennifer Macadam, Jared Gibbons, Xin Dai

Browse all Datasets

Improving the quality of irrigated pastures can increase the profitability of ruminant production systems. Increasing pasture plant biodiversity is beneficial for ruminants, pollinators, and soil health, but it is challenging to manage weed incursion in seeded mixed-species pastures. This study assessed the weed incursion that resulted when forage legumes or grasses were seeded as binary mixtures with one of four non-legume forbs. Defoliation occurred at 6-week intervals as either mowing or mob grazing. Forbs were chicory, plantain, Lewis flax, or small burnet and forages were alfalfa, birdsfoot trefoil, creeping foxtail, intermediate wheatgrass, kura clover, meadow bromegrass, orchardgrass, perennial ryegrass, reed …

It's Time To Re-Evaluate The Reporting Of Common Measures From Isokinetic Dynamometers: Isokinetic For Torque, Isotonic For Power, Brennan J. Thompson

Kinesiology and Health Science Faculty Publications

Isokinetic dynamometry is commonly used to provide an objective and reliable assessment of muscle function across a variety of clinical, athletic and research settings. Important muscle function variables that are commonly assessed are torque- and power-related measures. Isokinetic mode is overwhelmingly used to provide these variables, and has been so for decades; however, this mode may not be the best suited to examine power variables. The article aims to explore this issue through conceptual evaluation and empirical results using unpublished data. The implication is that due to the almost complete lack of unique information that power provides additional to torque …

Determining Spatial Responses Of Fishers (Pakania Pennanti) To Mechanical Treatments Of Forest Stands For Fuel Reduction, Tessa R. Smith, Eric M. Gese, R. David Clayton, Patricia A. Terletzky, Kathryn L. Purcell, Craig M. Thompson

Wildland Resources Faculty Publications

Historical forestry practices (e.g., fire suppression, heavy timber logging) have contributed to a discernable change in stand composition of western forests in the U.S., which now comprise a tinderbox mixture of increased surface and ladder fuels, dense stands, and fire-intolerant species. Forest managers are mitigating this concern by implementing silviculture practices (e.g., selective logging, thinning, prescribed burning) to reduce fuel loads and improve stand resiliency. Concern for habitat specialists, such as the fisher (Pekania pennanti), have arisen as they may be negatively influenced in the short-term by modifications to their environment that are needed to ensure long-term habitat …

Lake Powell Fish Sampling: Glen Canyon Dam Forebay Area, 2022 And 2023, Phaedra Budy, Casey Pennock

Browse all Datasets

Native fishes face imperilment due to habitat loss and fragmentation, megadrought, invasive species, and synergies amongst threats. These threats coalesce at Glen Canyon Dam (GCD), which impounds the Colorado River to create Lake Powell, a reservoir inhabited by a suite of nonnative fishes. Water level in Lake Powell has declined precipitously due to water overallocation and megadrought, increasing the risk of nonnative fish entrainment through the dam, as the penstocks draw water from the epilimnion. Our goal was to characterize the distribution and abundance of nonnative fishes in the vicinity of GCD and identify environmental conditions that may increase entrainment. …

Sewing With Fur, Cory Farnsworth

All Current Publications

Today, trapping is one of the most regulated activities worldwide and is a useful tool in managing excess populations of furbearers and struggling populations of prey animals. Fur is slowly regaining popularity as people recognize it as more ethical, humane, economical, and renewable, but the ability to use fur is becoming a lost art. It is part of our heritage as a people and connects us with the land. Learning to sew fur projects can be fun and, in some cases, quite profitable, as fur sewn into an article will sell far above the price of the pelt itself. If …

Impacts Of Changing Temperatures On The Water Budget In The Great Salt Lake Basin, Grace Affram, Jihad Othman, Reza Morovati, Saddy Pineda Castellanos, Sajad Khoshnoodmotlagh, Diana Dunn, Braedon Dority, Katherine Osorio Diaz, Cody Ratterman, Wei Zhang

Plants, Soils and Climate Student Research

Quantifying the water budget in the Great Salt Lake (GSL) basin is a nontrivial task, especially under a changing climate that contributes to increasing temperatures and a shift towards more rainfall and less snowfall. This study examines the potential impacts of temperature thresholds on the water budget in the GSL, emphasizing the influence on snowmelt, evapotranspiration (ET), and runoff under varying climate warming scenarios. Current hydrological models such as the Variable Infiltration Capacity (VIC) model use a universal temperature threshold to partition snowfall and rainfall across different regions. Previous studies have argued that there is a wide range of thresholds …

Pantoea agglomerans is one of four Pantoea species reported in the USA to cause bacterial rot of onion bulbs. However, not all P. agglomerans strains are pathogenic to onion. We characterized onion-associated strains of P. agglomerans to elucidate the genetic and genomic signatures of onion-pathogenic P. agglomerans. We collected > 300 P. agglomerans strains associated with symptomatic onion plants and bulbs from public culture collections, research laboratories, and a multi-year survey in 11 states in the USA. Combining the 87 genome assemblies with 100 high-quality, public P. agglomerans genome assemblies we identified two well-supported P. agglomerans phylogroups. Strains causing severe …

Microbiome Metabolic Capacity Is Buffered Against Phylotype Losses By Functional Redundancy, Kayla Cross, Noelle Beckman, Benjamin Jahnes, Zakee L. Sabree

Biology Faculty Publications

Many animals contain a species-rich and diverse gut microbiota that likely contributes to several host-supportive services that include diet processing and nutrient provisioning. Loss of microbiome taxa and their associated metabolic functions as result of perturbations may result in loss of microbiome-level services and reduction of metabolic capacity. If metabolic functions are shared by multiple taxa (i.e., functional redundancy), including deeply divergent lineages, then the impact of taxon/function losses may be dampened. We examined to what degree alterations in phylotype diversity impact microbiome-level metabolic capacity. Feeding two nutritionally imbalanced diets to omnivorous Periplaneta americana over 8 weeks reduced the diversity …

“It Was Oddly Cathartic And Just Good - Freeing”: An Adaptation Of A Cognitive Restructuring Task For Non-Binary People Experiencing Sexual Objectification, Lee R. Pradell, Joshua G. Parmenter, Renee V. Galliher, Elizabeth Grace Wong, Kevin Chi, Hanna Huenemann, Lindsey Rowley, Sadie South

Psychology Student Research

The present study uses action research and critical trans theory frameworks to adapt a cognitive restructuring task to assist non-binary people in minimizing internalization from sexual objectification experiences (SOEs). Nine non-binary participants completed process charts documenting their experiences with SOEs. Participants also completed interviews about their experience with the process chart. Findings explored the nine categories of the process chart and the process of completing the process charts, highlighting the power participants reclaimed by interrogating objectifying sentiments and managing their environments in the wake of SOEs. We discuss utilizing our study’s process chart to better support marginalized people through SOEs.

Iterative Refinement Of Arbitrary Micro-Optical Surfaces, Megan Plummer, Stephen Taylor, Matthew Marshall, David Brown, Robert Leonard, Seth Hyra, Spencer E. Olson

Space Dynamics Laboratory Publications

We introduce an adaptive optical refinement method enabling ultra-precise micro-milling of arbitrary surfaces. Through repeated iteration, our method reduces surface error without requiring significant specific surface engineering. This remediates the long sample preparation times and lack of refinement capability that previously reported methods suffer from. The iterative refinement milling method was used to produce spherical mirrors with small radii of curvature and low surface roughness for use in micro Fabry-Perot cavities. We demonstrate the use of this adaptive process to produce a variety of arbitrary surface geometries on both optical fiber tips as well as optical flats. We additionally discuss …

Wildland Resources Faculty Publications

The Great Salt Lake (GSL) is the largest saline lake in the Western Hemisphere. It supports billion-dollar industries and recreational activities, and is a vital stopping point for migratory birds. However, little is known about the spatiotemporal variation of phytoplankton biomass in the lake that supports these resources. Spectral reflectance provided by three remote sensing products was compared relative to their relationship with field measurements of chlorophyll a (Chl a). The MODIS product MCD43A4 with a 500 m spatial resolution provided the best overall ability to map the daily distribution of Chl a. The imagery indicated significant spatial …

Wildland Resources Faculty Publications

As the primary pollinator for many crops, honey bees (Apis mellifera) are critically important to food production and the agricultural economy. Adult mosquito control is often suspected by the public and commercial beekeepers to harm honey bees, creating conflicts between industries. To investigate this matter, a two-year field study was conducted on vegetated wetlands in Salt Lake City, Utah, U.S.A. where honey bee colonies were placed in areas subjected to aerial adult mosquito control applications using the organophosphate naled. Comparison colonies were placed in areas not exposed to insecticides. Colony conditions were documented over the two-year period to …

Lipoprotein(A) Response To Dietary Saturated Fat Reduction: Relationship To Apolipoprotein(A) Size Polymorphism In African Americans, Hayley G. Law, Munkhtuya Myagmarsuren, Heejung Bang, Wei Zhang, Michael Lefevre, Lars Berglund, Byambaa Enkhmaa

Human Development and Family Studies Faculty Publications

Background/Objectives: An elevated lipoprotein(a) [Lp(a)] level, which is a prevalent cardiovascular risk factor, is genetically determined by a size polymorphism of its apolipoprotein(a) [apo(a)] component. Despite its genetic control, Lp(a) level increases in response to dietary saturated fat (SFA) reduction. We tested the roles of apo(a) size and characteristics in modulating Lp(a) response to SFA reduction. Methods: We assessed apo(a) characteristics in 165 African Americans experiencing a 24% Lp(a) increase resulting from SFA reduction [16% at an average American Diet diet (AAD) to 6% at a DASH-type diet]. Apo(a) effects were tested based on the following factors: (1) the presence …

A new proliferation of optical instruments that can be attached to towers over or within ecosystems, or ‘proximal’ remote sensing, enables a comprehensive characterization of terrestrial ecosystem structure, function, and fluxes of energy, water, and carbon. Proximal remote sensing can bridge the gap between individual plants, site-level eddy-covariance fluxes, and airborne and spaceborne remote sensing by providing continuous data at a high-spatiotemporal resolution. Here, we review recent advances in proximal remote sensing for improving our mechanistic understanding of plant and ecosystem processes, model development, and validation of current and upcoming satellite missions. We provide current best practices for data availability …
