Dietary Intervention With Black Raspberries To Reduce Colitis Symptoms In Mice Fed Either Standard Ain93g Diet Or The Total Western Diet (P05-021-19), Daphne Michelle Rodriguez Jimenez, Michaela Brubaker, Elizabeth Park, Canyon Neal, Korry Hintze, Abby D. Benninghoff

Chemistry and Biochemistry Faculty Publications

Approximately 1.4 million people suffer from inflammatory bowel disease, which is a major risk factor for developing colitis associated colorectal cancer (CAC). Dietary interventions with the goal to reduce colon inflammation and encourage gut microbiome homeostasis may be a strategy to reduce the risk of CAC. The antioxidants and anti-inflammatory compounds present in black raspberries (BRB) have demonstrated protective effects in the colon epithelium and may alter the composition of the gut microbiome. Previously, we showed that dietary supplementation with black raspberries significantly suppressed colitis and colon tumorigenesis promoted by the consumption of a Western type diet in mice. The …

Dynamics Of Measured And Simulated Dissolved Phosphorus In Runoff From Winter-Applied Dairy Manure, Peter A. Vadas, Melanie N. Stock, Francisco J. Arriaga, Laura Ward Good, Krishnapuram G. Karthikeyan, Zachariah P. Zopp

Plants, Soils, and Climate Faculty Publications

Agricultural P loss from fields is an issue due to water quality degradation. Better information is needed on the P loss in runoff from dairy manure applied in winter and the ability to reliably simulate P loss by computer models. We monitored P in runoff during two winters from chisel-tilled and no-till field plots that had liquid dairy manure applied in December or January. Runoff total P was dominated by nondissolved forms when soils were bare and unfrozen. Runoff from snow-covered, frozen soils had much less sediment and sediment-related P, and much more dissolved P. Transport of manure solids was …

Approximation Techniques For Stochastic Analysis Of Biological Systems, Thakur Neupane, Zhen Zhang, Curtis Madsen, Hao Zheng, Chris J. Myers

Electrical and Computer Engineering Faculty Publications

There has been an increasing demand for formal methods in the design process of safety-critical synthetic genetic circuits. Probabilistic model checking techniques have demonstrated significant potential in analyzing the intrinsic probabilistic behaviors of complex genetic circuit designs. However, its inability to scale limits its applicability in practice. This chapter addresses the scalability problem by presenting a state-space approximation method to remove unlikely states resulting in a reduced, finite state representation of the infinite-state continuous-time Markov chain that is amenable to probabilistic model checking. The proposed method is evaluated on a design of a genetic toggle switch. Comparisons with another state-of-the-art …

Mind The Gap: Experimental Tests To Improve Efficacy Of Fladry For Nonlethal Management Of Coyotes, Julie K. Young, John P. Draper, Stewart Breck

Ecology Center Publications

Coyotes (Canis latrans) are the top predator of livestock in the contiguous United States. Developing more effective nonlethal tools to prevent coyote depredation will facilitate coexistence between livestock producers and coyotes. Fladry is a nonlethal deterrent designed to defend livestock by creating a visual barrier to wolves (C. lupus). Fladry may also be effective with coyotes, but large gap spacing between flags may reduce its efficacy. To address this issue, we performed 2 experiments on captive coyotes using fladry modified to reduce gap spacing at the U.S. Department of Agriculture, Predator Research Facility in Millville, Utah, …

A Homeotic Shift Late In Development Drives Mimetic Color Variation In A Bumble Bee, Li Tian, Sarthok Rasique Rahman, Briana D. Ezray, Luca Franzini, James P. Strange, Patrick Lhomme, Heather M. Hines

All PIRU Publications

Natural phenotypic radiations, with their high diversity and convergence, are well-suited for informing how genomic changes translate to natural phenotypic variation. New genomic tools enable discovery in such traditionally nonmodel systems. Here, we characterize the genomic basis of color pattern variation in bumble bees (Hymenoptera, Apidae, Bombus), a group that has undergone extensive convergence of setal color patterns as a result of Müllerian mimicry. In western North America, multiple species converge on local mimicry patterns through parallel shifts of midabdominal segments from red to black. Using genome-wide association, we establish that a cis-regulatory locus between the abdominal …

Listen To Us: Dad-Endorsed Strategies For Ehdi Professionals, Holly F. Pedersen Dr., Jerusha Olthoff

Journal of Early Hearing Detection and Intervention

While fathers play an increasingly important role in today’s families, there is an imbalance of research regarding fathers of children with disabilities compared to mothers. Modest research with mothers of children who are deaf/hard of hearing exists; however, very limited research is available specific to fathers of that population. With the advent of newborn hearing screening, the number of children who have hearing loss being identified within the first six months of life has significantly increased. Thus, the number of fathers participating in EHDI services has also increased. Seeking to answer the question, What do fathers’ experiences in the early …

Twentieth Century Geomorphic Changes Of The Lower Green River In Canyonlands National Park, Utah: An Investigation Of Timing, Magnitude And Process, Alexander E. Walker, John C. Schmidt, Paul E. Grams

Watershed Sciences Faculty Publications

Since the early 20^th century, the Green River, the longest tributary of the Colorado River, has narrowed, decreasing available riparian and aquatic habitat.

Initially, the widespread establishment of non-native tamarisk was considered to be the primary driver of channel narrowing. An alternative hypothesis postulated that changes in hydrology drove narrowing. Reductions in total streamflow and changes to flow regime occurred due to wide-spread water development, decreased snowmelt flood magnitude, and the increased cyclicity of wet and dry years. The two hypotheses agree on channel narrowing, but each influences modern river management differently. A tamarisk-driven model of narrowing implies that …

Foraging Economics Of The Hunt Bumble Bee, A Viable Pollinator For Commercial Agriculture, Abby Baur, James P. Strange, Jonathan B. Koch

All PIRU Publications

Globally, there are only five bumble bee (Hymenoptera: Apidae, Bombus) species that have been successfully commercialized for agriculture. The Hunt bumble bee, Bombus huntii Green, 1860, has been recognized as a suitable pollinator of crops and has a broad distribution in western North America, making it a viable candidate for commercialization. In this study, our goal was to characterize the foraging dynamics of B. huntii female workers under open field conditions. To accomplish this goal, we monitored three B. huntii colonies over an 8-wk period in the summer of 2012 in northern Utah. Using marked bees, we studied the …

Pasture Chemoscapes And Their Ecological Services, Juan J. Villalba, Karen A. Beauchemin, Pablo Gregorini, Jennifer W. Macadam

Wildland Resources Faculty Publications

Ruminant livestock-production systems are between a rock and a hard place; they are experiencing increasing societal pressure to reduce environmental impacts in a world that demands increased food supply. Recent improvements in the understanding of the nutritional ecology of livestock by scientists may help livestock producers respond to these seemingly contradictory demands. Forages are nutrition and pharmacy centers with primary (nutrients) and plant secondary compounds (PSC; pharmaceuticals, nutraceuticals), which can provide multiple services for the proper functioning of agroecosystems. Legumes with lower contents of fiber and higher contents of nonstructural carbohydrates, coupled with different types and concentrations of PSC (e.g., …

Interfacial Amino Acids Support Spa47 Oligomerization And Shigella Type Three Secretion System Activation, Hannah J. Demler, Heather B. Case, Yalemi Morales, Abram R. Bernard, Sean J. Johnson, Nicholas E. Dickenson

Chemistry and Biochemistry Faculty Publications

Like many Gram-negative pathogens, Shigella rely on a type three secretion system (T3SS) for injection of effector proteins directly into eukaryotic host cells to initiate and sustain infection. Protein secretion through the needle-like type three secretion apparatus (T3SA) requires ATP hydrolysis by the T3SS ATPase Spa47, making it a likely target for in vivo regulation of T3SS activity and an attractive target for small molecule therapeutics against shigellosis. Here, we developed a model of an activated Spa47 homo-hexamer, identifying two distinct regions at each protomer interface that we hypothesized to provide intermolecular interactions supportingSpa47 oligomerization and enzymatic activation. Mutational analysis …

Forty Years Of Progress In The Study Of The Hydrogen Bond, Steve Scheiner

Chemistry and Biochemistry Faculty Publications

The author looks back at developments over the last few decades concerning the H–bond. The list of atoms involved as proton donor and acceptor has broadened dramatically, including most electronegative atoms and even metals. The factors that control the transfer of the proton across the H–bond have been elucidated and show the importance of even minor changes in its geometry. Small stretches can shut down the transfer entirely, and certain bends can force a proton to transfer against a pK gradient. Along with the recognition that a CH..O interaction can represent a true H–bond, and one with strength comparable to …

Attendance Trends Threaten Future Operations Of America’S State Park Systems, Jordan Smith, Emily J. Wilkins, Yu-Fai Leung

Environment and Society Faculty Publications

This research examines how the operating expenditures of America’s state park systems will be affected by a continued growth in attendance consistent with observed trends as well as potential climate futures. We construct a longitudinal panel dataset (1984–2017) describing the operations and characteristics of all 50 state park systems. These data are analyzed with a time-varying stochastic frontier model. Estimates from the model are used to forecast operating expenditures to midcentury under four different scenarios. The first scenario assumes annual attendance within each state park system will continue to grow (or decline) at the same average annual rate that it …

Apospory And Diplospory In Diploid Boechera (Brassicaceae) May Facilitate Speciation By Recombination-Driven Apomixis-To-Sex Reversals, John G. Carman, Mayelyn Mateo De Arias, Lei Gao, Xinghua Zhao, Becky M. Kowallis, David A. Sherwood, Manoj K. Srivastava, Krishna K. Dwivedi, Bo J. Price, Landon Watts, Michael D. Windham

Plants, Soils, and Climate Faculty Publications

Apomixis (asexual seed formation) in angiosperms occurs either sporophytically, through adventitious embryony, or gametophytically, where an unreduced female gametophyte (embryo sac) forms and produces an unreduced egg that develops into an embryo parthenogenetically. Multiple types of gametophytic apomixis occur, and these are differentiated based on where and when the unreduced gametophyte forms, a process referred to as apomeiosis. Apomeiotic gametophytes form directly from ameiotic megasporocytes, as in Antennaria-type diplospory, from unreduced spores derived from 1st division meiotic restitutions, as in Taraxacum-type diplospory, or from cells of the ovule wall, as in Hieracium-type apospory. Multiple types of apomeiosis occasionally occur in …

Assessing The Utility Of Conserving Evolutionary History, Caroline M. Tucker, Tracy Aze, Marc W. Cadotte, Juan L. Cantalapiedra, Chelsea Chisholm, Sandra Díaz, Richard Grenyer, Danwei Huang, Florent Mazel, William D. Pearse, Matthew W. Pennell, Marten Winter, Arne O. Mooers

Ecology Center Publications

It is often claimed that conserving evolutionary history is more efficient than species‐based approaches for capturing the attributes of biodiversity that benefit people. This claim underpins academic analyses and recommendations about the distribution and prioritization of species and areas for conservation, but evolutionary history is rarely considered in practical conservation activities. One impediment to implementation is that arguments related to the human‐centric benefits of evolutionary history are often vague and the underlying mechanisms poorly explored. Herein we identify the arguments linking the prioritization of evolutionary history with benefits to people, and for each we explicate the purported mechanism, and evaluate …

Space Use And Movement Of Urban Bobcats, Julie K. Young, Julie M. Golla, John P. Draper, Derek Broman, Terry Blankenship, Richard Heilbrun

Wildland Resources Faculty Publications

Global urbanization is rapidly changing the landscape for wildlife species that must learn to persist in declining wild spacing, adapt, or risk extinction. Many mesopredators have successfully exploited urban niches, and research on these species in an urban setting offers insights into the traits that facilitate their success. In this study, we examined space use and activity patterns from GPS-collared bobcats (Lynx rufus) in the Dallas–Fort Worth metroplex, Texas, USA. We found that bobcats select for natural/agricultural features, creeks, and water ways and there is greater home-range overlap in these habitats. They avoid roads and are less likely …

Carbon Control On Terrestrial Ecosystem Function Across Contrasting Site Productivities: The Carbon Connection Revisited, Nicholas C. Dove, John M. Stark, Gregory S. Newman, Stephen C. Hart

Ecology Center Publications

Understanding how altered soil organic carbon (SOC) availability affects microbial communities and their function is imperative in predicting impacts of global change on soil carbon (C) storage and ecosystem function. However, the response of soil microbial communities and their function to depleted C availability in situ is unclear. We evaluated the role of soil C inputs in controlling microbial biomass, community composition, physiology, and function by (1) experimentally excluding plant C inputs in situ for 9 yr in four temperate forest ecosystems along a productivity gradient in Oregon, USA; and (2) integrating these findings with published data from similar C‐exclusion …

Combining Geographic Information Systems And Agent-Based Models In Archaeology: Part 2 Of 3, Benjamin Davies, Iza Romanowska, Kathryn Harris, Stefani Crabtree

Environment and Society Faculty Publications

Archaeologists are using spatial data in increasingly sophisticated analyses and invoking more explicit considerations of space in their interpretations. Geographic information systems (GIS) have become standard technology for professional archaeologists in the collection and management of spatial data. Many calls have been made to develop and adapt digital geospatial technologies for interpretation and understanding past social dynamics, but this has been limited to some extent by the static nature of map-oriented GIS approaches. Here, we illustrate how coupling GIS with agent-based modeling (ABM) can assist with more dynamic explorations of past uses of space and geospatial phenomena.

Ectoparasite Burden Influences The Denning Behavior Of A Small Desert Carnivore, Bryan M. Kluever, David T. Iles, Eric M. Gese

Wildland Resources Faculty Publications

Quantifying the impacts of parasitism on a host can be arduous and is generally understudied for ectoparasites, with known works being either laboratory‐focused, correlational‐based, or only focusing on a few species and spatial extents. Many mammalian species have evolved the modality of denning behavior, a lifestyle that can lead to higher ectoparasite burden, and it has been posited that animals may alter their denning behavior in an attempt to reduce exposure to ectoparasites. We conducted a test of the ectoparasite release hypothesis for kit foxes (Vulpes macrotis) and fleas in the Great Basin Desert of the western United …

Antifungal Activities Of 4”,6”-Disubstituted Amphiphilic Kanamycins, Madher N. Alfindee, Yagya Prasad Subedi, Michelle M. Grilley, Jon Y. Takemoto, Cheng-Wei Tom Chang

Biology Faculty Publications

Amphiphilic kanamycins derived from the classic antibiotic kanamycin have attracted interest due to their novel bioactivities beyond inhibition of bacteria. In this study, the recently described 4″,6″-diaryl amphiphilic kanamycins reported as inhibitors of connexin were examined for their antifungal activities. Nearly all 4″,6″-diaryl amphiphilic kanamycins tested had antifungal activities comparable to those of 4″,6″-dialkyl amphiphilic kanamycins, reported previously against several fungal strains. The minimal growth inhibitory concentrations (MICs) correlated with the degree of amphiphilicity (cLogD) of the di-substituted amphiphilic kanamycins. Using the fluorogenic dyes, SYTOX^TM Green and propidium iodide, the most active compounds at the corresponding MICs or at …
