Concentrated Flow Erodibility For Physically Based Erosion Models: Temporal Variability In Disturbed And Undisturbed Rangelands, Osama Z. Al-Hamdan, Frederick B. Pierson, Mark A. Nearing, C. Jason Williams, Jeffry J. Stone, Patrick R. Kormos, Jan Boll, Mark A. Weltz

Articles

Current physically based overland flow erosion models for rangeland application do not separate disturbed and undisturbed conditions in modeling concentrated flow erosion. In this study, concentrated flow simulations on disturbed and undisturbed rangelands were used to estimate the erodibility and to evaluate the performance of linear and power law equations that describe the relationship between erosion rate and several hydraulic parameters. None of the hydraulic parameters consistently predicted the detachment capacity well for all sites, however, stream power performed better than most of other hydraulic parameters. Using power law functions did not improve the detachment relation with respect to that …

Carrying Biomath Education In A Leaky Bucket, James A. Powell, Brynja R. Kohler, James W. Haefner, Janice Bodily Jul 2012

Carrying Biomath Education In A Leaky Bucket, James A. Powell, Brynja R. Kohler, James W. Haefner, Janice Bodily

Mathematics and Statistics Faculty Publications

In this paper, we describe a project-based mathematical lab implemented in our Applied Mathematics in Biology course. The Leaky Bucket Lab allows students to parameterize and test Torricelli’s law and develop and compare their own alternative models to describe the dynamics of water draining from perforated containers. In the context of this lab students build facility in a variety of applied biomathematical tools and gain confidence in applying these tools in data-driven environments. We survey analytic approaches developed by students to illustrate the creativity this encourages as well as prepare other instructors to scaffold the student learning experience. Pedagogical results …

Root Niche Partitioning Among Grasses, Saplings, And Trees Measured Using A Tracer Technique, Andrew Kulmatiski, Karen H. Beard Jul 2012

Root Niche Partitioning Among Grasses, Saplings, And Trees Measured Using A Tracer Technique, Andrew Kulmatiski, Karen H. Beard

Wildland Resources Faculty Publications

Niche partitioning of resources by plants is believed to be a fundamental aspect of plant coexistence and biogeochemical cycles; however, measurements of the timing and location of resource use are often lacking because of the difficulties of belowground research. To measure niche partitioning of soil water by grasses, planted saplings, and trees in a mesic savanna (Kruger National Park, South Africa), we injected deuterium oxide into 102,000 points in 15, 154-m2 plots randomly assigned to one of five depths (0–120 cm) and one of three time periods during the 2008/2009 growing season. Grasses, saplings and trees all demonstrated an exponential …

Bark Beetles, Ryan S. Davis, Darren Mcavoy Jul 2012

Bark Beetles, Ryan S. Davis, Darren Mcavoy

All Current Publications

Bark beetles are one of the most destructive forest pests in the world. They are different than the larger longhorned and roundheaded/metallic woodboring beetles commonly infesting the inner wood of trees. The largest bark beetle, the red turpentine beetle (Dendroctonus valens), reaches only 8.3 mm in length. Because of their tiny size, bark beetles are not effective tree killers as individuals.

Facilitation Drives Mortality Patterns Along Succession Gradients Of Aspen-Conifer Forests, W. John Calder, Samuel B. St. Clair Jun 2012

Facilitation Drives Mortality Patterns Along Succession Gradients Of Aspen-Conifer Forests, W. John Calder, Samuel B. St. Clair

Aspen Bibliography

While it is well established that facilitation and competition are important structuring forces in plant communities, a clear understanding of the interactions between them and how they change through the life stages of plants and affect long-term plant community development is lacking. We have observed that conifer seedlings are rarely found growing in meadows but readily establish under adjacent aspen stands, particularly at the base of aspen trees, creating the potential for antagonistic interactions in later life stages. To examine these relationships and their potential consequences on forest community development, we characterized patterns of establishment, regeneration, and overstory mortality of …

Caehnorhabditis Elegans: A Low-Cost In Vivo Animal Model For Efficacy Studies Of Novel Antibiotics, Rylee Ann Gregory Jun 2012

Caehnorhabditis Elegans: A Low-Cost In Vivo Animal Model For Efficacy Studies Of Novel Antibiotics, Rylee Ann Gregory

Undergraduate Honors Capstone Projects

Since the 1940s, antibiotics have greatly reduced the adverse effects of infectious diseases caused by microbes. However, due to excessive, and often incorrect, use of known antibiotics, many organisms have adapted antibiotic resistance. Currently, over 70% of known infectious bacteria are resistant to at least one antibiotic. In the U.S. , 90,000 deaths occur each year due to infection by bacteria resistant to antibiotics. This number has increased by nearly 75,000 in the last 20 years. It is necessary, therefore, to continue developing new antibiotics in an effort to keep up with increasing antibiotic resistance. Traditional in vitro and whole …

The Great Salt Lake’S Deep Brine Layer And Its Importance For Mercury Bioaccumulation In Brine Shrimp (Artemia Franciscana), Wayne A. Wurtsbaugh, Erin F. Jones May 2012

The Great Salt Lake’S Deep Brine Layer And Its Importance For Mercury Bioaccumulation In Brine Shrimp (Artemia Franciscana), Wayne A. Wurtsbaugh, Erin F. Jones

Watershed Sciences Faculty Publications

Mercury in water bodies is receiving increased attention due to the toxicity of methylmercury (MeHg). Some authors have suggested that stratified lakes with anoxic hypolimnia experience higher rates of mercury methylation. It is believed that this biochemical pathway is promoted by high levels of H2S and organic matter in the deep layers that fuel sulfate‐reducing bacteria that produce methylmercury as a byproduct.

In Vitro Regeneration Of Rudbeckia Hirta ‘Plainview Farm’ From Leaf Tissue, Youping Sun, Lijuan Han, Donglin Zhang

Plants, Soils, and Climate Faculty Publications

Rudbeckia hirta ‘Plainview Farm’, a new multiple-layered ray flowered cultivar, shows potential for potted plant production. After years of seed germination, this specific flower morphological trait was still unstable from generation to generation. To maintain its unique features, leaf sections (0.25 cm2 ) were cultured on Murashige and Skoog (MS) medium supplemented with either BA (0.5, 1.0, or 2.0 mg·L1 ), KIN (2.5, 5, or 10 mg·L-1 ), or ZT (0.5, 1.0, or 2.0 mg·L-1 )toinduce callus and microshoots. After cultivation for 33 days, all cytokinin treatments significantly induced callus and the callus size were 1.5- to-2.4-fold bigger than those …

The Planar Electrode Linear Ion Trap, Brett Hansen, Hannah Quist, Aaron Hawkins, Daniel Austin May 2012

The Planar Electrode Linear Ion Trap, Brett Hansen, Hannah Quist, Aaron Hawkins, Daniel Austin

Utah Space Grant Consortium

We present a linear type ion trap consisting of metal lines that are lithographically patterned onto two ceramic substrates. Trapping fields are realized by applying specific voltage potentials to each line. This arrangement allows miniaturization approaches that are immune to surface roughness issues and increased complexities of precision machining of electrode surfaces. We also present how these traps allow a thorough study of higher order multipoles and their effect on mass analyzer performance.

Locking Down The N-Terminus Of Prmt1 In Order To Assess The Role Of Motion In Activity, Taylor James Rasmussen May 2012

Locking Down The N-Terminus Of Prmt1 In Order To Assess The Role Of Motion In Activity, Taylor James Rasmussen

Undergraduate Honors Capstone Projects

Protein arginine methyltransferases (PRMTs) are involved In many major biological pathways in the human body. Processes that demonstrate arginine methylation by PRMTs include, but are not limited to, histone modification, DNA transcription, and post-translational protein modifications. Although recent research has allowed the identification of several PRMT isoforms and exposed their involvement in these processes, relatively little is known about the details of how these enzymes perform their biochemical duties. It is currently hypothesized that the N-terminus of PRMT variant I is involved in recognizing substrates and aiding in catalysis by virtue of a change in its conformation. To understand how …

A Study Of The Spawning Ecology And Early Life History Survival Of Bonneville Cutthroat Trout, Phaedra E. Budy, Sarah Wood, Brett B. Roper

Watershed Sciences Faculty Publications

We completed a large-scale field experiment in four tributaries of the Logan River, Utah, where the largest metapopulation of imperiled Bonneville cutthroat trout Oncorhynchus clarkii utah persists. We documented the spatial and temporal distributions of spawners, quantified substrate use versus substrate availability, and evaluated differences in hatch and emergence fry success between and among sites in relation to habitat characteristics. We observed considerable variability in the timing, magnitude, and duration of spawning among study areas (streams), in part as a function of a variable, multipeaked hydrograph. Nevertheless, across study areas, >70% of redds were constructed on the final descending limb …

Information Flow In The Spatiotemporal Dynamics Of Cellular Automata, Akshay Thakre May 2012

Information Flow In The Spatiotemporal Dynamics Of Cellular Automata, Akshay Thakre

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Decision making in natural systems, such as the body's immune response to a potential pathogen or a bacterial colony's initiation of fruiting due to food scarcity, is distributed over many cells that posses only local information, and not determined globally. Understanding how accurate decisions can be made in such systems where no individual decisions maker has complete information has important implications in distributed software and can provide insights into the biological evolution of complexity. In this work, the process of distributed decision making is modeled using the majority problem in cellular automata, and information theoretic measures of Kolmogorov complexity are …
