Chapter 2 Switchgrass Breeding, Genetics, And Genomics, Michael D. Casler

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Switchgrass was one of the dominant species of the North American tallgrass prairie and savanna ecosystems that once dominated a large portion of the continent. It is currently used for pasture, hay production, soil conservation, and biomass production for conversion to energy. Switchgrass was selected in 1992 as the herbaceous model species to develop dedicated cellulosic bioenergy crops. Breeding and genetics studies began on switchgrass in the 1950s, focused on utilization in livestock agriculture. Recent developments have rapidly increased the rate of gain for biomass yield, largely by increasing the focus and intensity of selection and improving the choice of …

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Aim Effects of elevated CO₂ on N relations are well studied, but effects on other nutrients, especially micronutrients, are not. We investigated effects of elevated CO₂ on response to variation in boron (B) availability in three unrelated species: seed geranium (Pelargonium x hortorum), barley (Hordeum vulgare), and water fern (Azolla caroliniana).

Methods Plants were grown at two levels of CO₂ (370, 700 ppm) and low, medium, and high B. Treatment effects were measured on biomass, net photosynthesis (P_n) and related variables, tissue nutrient concentrations, and B transporter protein BOR1. …

The Role Of Cax1 And Cax3 In Elemental Distribution And Abundance In Arabidopsis Seed, Tracy Punshon, Kendall Hirschi, Jian Yang, Antonio Lanzirotti, Barry Lai, Mary Lou Guerinot

Dartmouth Scholarship

The ability to alter nutrient partitioning within plants cells is poorly understood. In Arabidopsis (Arabidopsis thaliana), a family of endomembrane cation exchangers (CAXs) transports Ca²⁺ and other cations. However, experiments have not focused on how the distribution and partitioning of calcium (Ca) and other elements within seeds are altered by perturbed CAX activity. Here, we investigate Ca distribution and abundance in Arabidopsis seed from cax1 and cax3 loss-of-function lines and lines expressing deregulated CAX1 using synchrotron x-ray fluorescence microscopy. We conducted 7- to 10-μm resolution in vivo x-ray microtomography on dry mature seed and 0.2-μm resolution x-ray …

Psychology And People Living With Hiv/Aids: A Critical Review Of The Literature, David Fischer

Theses and Dissertations

The implications of living with Human Immunodeficiency Virus (HIV) have evolved over the last 30 years. The view of HIV infection as an imminent death sentence has largely disappeared. From a practical perspective, HIV positive status is now medically treated as a chronic illness rather than as a terminal diagnosis. In response, the focus of psychological research and therapeutic practice has evolved to reflect the changing implications of living with HIV. This study documents how psychological literature regarding people living with HIV has changed over the course of the epidemic.

An Assessment Of Phosphorus Recovery From Dairy Wastewater, Éanna Kelleher

Theses

Phosphorus is an important nutrient for plant and animal life. It is one of the three essential nutrients required for plant growth; Nitrogen, Phosphorus and Potassium. It plays a vital role in the quality and structure of plants. In animals it is essential for the transfer of energy around the body and for the development of the skeleton. Phosphorus is mined from deposits of phosphate rock and is mainly used to produce fertiliser which is applied to agricultural land to improve plant growth. However, phosphorus is a finite resource and, similar to oil, is expected to peak during this century. …

An Elementary-To-Middle School Transitional Program And Its Effect On Student Behavior, Kyle Sheer

Abraham S. Fischler College of Education ETD Archive

The transition from elementary to middle school has proven to be difficult for all stakeholders. Reports of increased discipline infractions and truancy, combined with a noticeable drop in overall student achievement, have resulted in numerous attempts to ease the anxieties and frustrations that are characteristic of this transition. Schools often establish transitional programs to prepare incoming middle school students with the skills needed to be successful in a new educational environment. Transitional programs are often very expensive to operate and require an extensive amount of planning. This program evaluation considered 1 specific transitional program that took place during the summer …

Plant Community Restoration On Mima Mounds At Turnbull National Wildlife Refuge, Wa, Brandy K. Reynecke

EWU Masters Thesis Collection

"Prevention and management of exotic plant species invasion can diminish their negative ecological and economic impacts and maintain ecological functions provided by native species. This is particularly important in rare landscapes that provide essential habitat. The most successful management plans integrate techniques to reduce invasive species abundance, increase native species abundance and reduce invasibility. Eastern Washington's Channeled Scablands bioregion has highly fragmented remnant patches of grassland underlain by glacial alluvium and basalt bedrock that are dotted with Mima mounds (naturally occurring aggregations of fine particle soil). The mounds provide valuable habitat for native plants and animals and many have been …

Grazing On Synechococcus Spp. By The Red-Tide Dinoflagellate Karenia Brevis: Implications For Bloom Dynamics In The Gulf Of Mexico, Leo A. Procise

OES Theses and Dissertations

Karenia brevis, the toxic dinoflagellate responsible for massive red tides in the Gulf of Mexico (GOM), causes fish kills, shellfish poisoning, and acute respiratory irritation in humans. Bloom initiation and maintenance have been linked to the physical environment as well as various nutrient input mechanisms. To date, efforts to quantify nitrogen (N) sources fueling K. brevis blooms in the GOM have not included mixotrophic grazing although many dinoflagellates, including K. brevis, are known to be capable of mixotrophy. This dissertation reports field and laboratory results demonstrating that natural bloom populations and K. brevisisolates from the West Florida …

Can We Reduce Eating Disorder Risk Factors In Female College Athletes? A Randomized Exploratory Investigation Of Two Peer-Led Interventions, Carolyn Becker, Leda Mcdaniel, Stephanie Bull, Marc Powell, Kevin Mcintyre

Psychology Faculty Research

Female athletes are at least as at risk as other women for eating disorders (EDs) and at risk for the female athlete triad (i.e., inadequate energy availability, menstrual disorders, and osteoporosis). This study investigated whether two evidence-based programs appear promising for future study if modified to address the unique needs of female athletes. Athletes were randomly assigned to athlete-modified dissonance prevention or healthy weight intervention (AM-HWI). ED risk factors were assessed pre/post-treatment, and 6-week and 1-year follow-up.
