Discovering Metabolic Networks Of Bovine Fertilization, Erin Lynn Young
Discovering Metabolic Networks Of Bovine Fertilization, Erin Lynn Young
Undergraduate Honors Capstone Projects
At the time of fertilization, a dramatic change occurs in the oocyte that transforms this cell from a metaphase arrested state into a metabolically active and dynamic state. The view of the flow of biological processes within organisms has recently shifted from that of a linear path to a more complex network. Biological processes are no longer thought of in the simple terms of DNA to RNA, RNA to proteins, and proteins to final activity. It is now known that many biological processes involve interconnected networks and feedback loops in which DNA, RNA, proteins, and metabolites perform specific roles. We …
Herbicide, Salinity, And Flooding Tolerance Of Foxtail Barley (Hordeum Jubatum L.) And Desirable Pasture Grasses, Karl R. Israelsen
Herbicide, Salinity, And Flooding Tolerance Of Foxtail Barley (Hordeum Jubatum L.) And Desirable Pasture Grasses, Karl R. Israelsen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Research trials performed in the greenhouse compared the tolerance and response of Hordeum jubatum and desirable pasture grass species to herbicides, salinity, and flooding. Desirable grass species used in this study included: 'Fawn' tall fescue (Festuca arundinaceae), 'Garrison' creeping foxtail (Alopecurus arundinaceus), 'Palaton' reed canarygrass (Phalaris arundinacea), 'Climax' timothy (Phleum pratense), 'Alkar' tall wheatgrass (Thinopyrum ponticum), 'Potomac' orchardgrass (Dactylis glomerata), and 'Mustang' altai wildrye (Leymus angustus). Tolerance to herbicides, salinity, and flooding varied significantly among grass species. Herbicide tolerance was tested using four herbicides at five …
Las Frambuesas De Otoño En Los Túneles Altos, Daniel Rowley, Brent Black, Trevin Cardon
Las Frambuesas De Otoño En Los Túneles Altos, Daniel Rowley, Brent Black, Trevin Cardon
All Current Publications
Se ha demostrado que los túneles altos son una manera eficaz para extender la temporada de crecimiento de la frambuesa en Utah y otras áreas de los Estados Unidos. Dependiendo del clima, los rendimientos de las frambuesas de otoño cultivados al aire libre pueden ser reducidos significativamente por la primera helada del otoño. Los túneles altos son una de las maneras de protección de la helada, y cuando se los usan junto con otras maneras de protección de la helada se puede extender significativamente la temporada de crecimiento. Investigadores en Nueva York han extendido eficazmente la temporada de crecimiento hasta …

Goatsrue (Galega Officinalis) Seed Biology, Control, And Toxicity, Michelle Oldham
Goatsrue (Galega Officinalis) Seed Biology, Control, And Toxicity, Michelle Oldham
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Goatsrue is an introduced perennial plant that has proven to have great invasive potential, leading to its classification as a noxious weed in many states and at the federal level. This research focused on seed biology, herbicide control, and toxic dynamics of goatsrue. Physical dormancy of mature goatsrue seed was tested through scarification using sulfuric acid with exposures of up to 60 minutes resulting in 100% germination. Comparison of dormancy for 26-year-old and 6-month-old goatsrue seed indicated aged seeds had reduced dormancy levels compared to newly harvested seeds, but had similar viability. Goatsrue seedling emergence was inversely related to burial …

A Survey Of Apomixis And Ploidy Levels Among Poa L. (Poaceae) Using Flow Cytometry, Alicia Michelle Kelley, Paul G. Johnson, Blair L. Waldron, Michael D. Peel
A Survey Of Apomixis And Ploidy Levels Among Poa L. (Poaceae) Using Flow Cytometry, Alicia Michelle Kelley, Paul G. Johnson, Blair L. Waldron, Michael D. Peel
CWEL Publications
Poa is a complex genus taxonomically and genetically. As a result, relatively little information exists for this economically important genus with regards to reproductive mode and variability in chromosome number. We examined apomixis frequency and ploidy levels in 83 Poa accessions representing 33 species from the National Plant Germplasm System using flow cytometric techniques. In reproductive mode analysis, we analyzed at least three preparations of 50 seeds each from the accessions. In ploidy level analysis, at least three plants of each accession were analyzed. Sixty percent of the species had at least one apomictic or facultative apomictic accession; 40% were …

Guide For Quantifying Fuels In The Sagebrush Steppe And Juniper Woodlands Of The Great Basin, Andrea Stebleton, Stephen Bunting
Guide For Quantifying Fuels In The Sagebrush Steppe And Juniper Woodlands Of The Great Basin, Andrea Stebleton, Stephen Bunting
Reports
Prescribed fire is increasingly used for fuels management and ecosystem restoration. Managers and fuels specialists of the Great Basin are often required to estimate fuel loadings to predict fire behavior, recommend fuel treatments, or restore an area to its natural fire regime. Because of invasive species and woodland encroachment, there have been extensive changes in the fire regimes of sagebrush steppe over the past 150 years. After two years of pre-treatment sampling across six states of the Great Basin, the Sagebrush Steppe Treatment and Evaluation Project (SageSTEP) measured many variables including vegetation, soils, hydrology, wildlife, and fuels. These data will …

Piñon And Juniper Field Guide: Asking The Right Questions To Select Appropriate Management Actions, Robin J. Tausch, R. F. Miller, B. A. Roundy, J. C. Chambers
Reports
Piñon-juniper woodlands are an important vegetation type in the Great Basin. Old-growth and open shrub savanna woodlands have been present over much of the last several hundred years. Strong evidence indicates these woodlands have experienced significant tree infilling and major expansion in their distribution since the late 1800s by encroaching into surrounding landscapes once dominated by shrubs and herbaceous vegetation. Both infilling and expansion affects soil resources, plant community structure and composition, water and nutrient cycles, forage production, wildlife habitat, biodiversity, and fire patterns across the landscape. Another impact is the shift from historic fire regimes to larger and more …
Optimization Of Soilless Media For Alkaline Irrigation Water, Cody Alexander Tramp, Julie K. Chard, Bruce Bugbee
Optimization Of Soilless Media For Alkaline Irrigation Water, Cody Alexander Tramp, Julie K. Chard, Bruce Bugbee
Hydroponics/Soilless Media
High root zone pH reduces nutrient availability and high alkalinity water is strongly buffered around an alkaline pH. Soilless media can be altered to improve nutrient availability. This study was conducted to optimize the composition of soilless media for use with high alkalinity water. Mixes of peat and/or perlite or vermiculite in 50/50 and 33/33/33 volumetric ratios were tested. In some studies, mixes were also amended with up to 2.4 g/L of dolomite limestone to neutralize the initial acidity of the peat. Mixes containing vermiculite settled more, had higher water holding capacity (WHC) and percent plant available water (%PAW), and …

Apache Plume In The Landscape, Heidi Kratsch
Apache Plume In The Landscape, Heidi Kratsch
All Archived Publications
Description: Apache plume is an evergreen shrub that can reach five feet tall and wide in a landscape setting. This plant’s most distinguishing and attractive feature is the feathery, red- turning-pink seedhead that emerges after the white rose-like, five-petaled flower fades. In the same family as Mexican cliffrose, both species produce similar deeply lobed small leaves; Apache plume’s leaves are lighter green and more finely textured. The bark becomes red and exfoliating with age. Apache plume is a dioecious species, requiring both male and female plants to produce viable seed.
