Drought And Stocking Rate Effects On Forage Yield From Western South Dakota Rangelands, Alexander J. Smart, Barry H. Dunn

SDSU Extension Extra Archives

The vegetation of rangelands in a large portion of western South Dakota is an overstory of cool-season grasses such as western wheatgrass and green needlegrass and an understory of warm-season grasses such as blue grama and buffalograss (Fig 1). In semi-arid environments, precipitation is the main factor that determines forage production. Many western South Dakota counties receive less than 17 inches of annual rainfall, with 75% occurring between April and October. Pastures are usually managed as large units (more than 160 acres) because fencing and water developments are costly. Regrowth is usually limited to the spring, and 90% of forage …

The Status Of Detainees From The Iraq And Afghanistan Conflicts, Srividhya Ragavan, Michael S. Mireles Jr.

Utah Law Review

The Bush administration has taken a position which attempts to dance around international law to achieve the objective of obtaining high quality information from detainees. There is no dispute that obtaining high quality information about future terrorist attacks is critical to preventing future attacks, but at what cost? A more prudent approach by the Bush administration would have been use of the worldwide support received after 9/11 to modify the international rules of law concerning the treatment of detainees of war on terror. At that point, the world would likely have been receptive to creating exceptions to international law to …

Public Lands And Law Reform: Putting Theory, Policy, And Practice In Perspective, Robert B. Keiter

Utah Law Review

It may be blinking reality, however, to expect Congress to remake public land policy in a single legislative act. Indeed, it will not be easy to produce meaningful reforms that will pass political muster, but Congress has done it before, and more than once. While crisis situations, like the early 1970s clearcutting controversy, have precipitated periodic statutory reforms, the need for more comprehensive reform is becoming increasingly apparent. The agencies have already begun the process, at the prodding of the public and the courts, by experimenting with new ecological sustainability policies and collaborative conservation models. But old tensions persist. It …

Bufadienolides In The Chemical Defenses Of The Toads, Bufo Americanus And Bufo Fowleri, Catherine E. Merovich

Dissertations

I investigated the steroidal chemical defenses (bufadienolides) of Bufo americanus and Bufo fowleri. By the nature of their complex, biphasic life cycles, toads, like other amphibians are important components of aquatic and terrestrial habitats and are prey to numerous invertebrates and vertebrates. Bufadienolides are presumed to be important anti-predatory compounds although much of their chemical ecology is poorly understood. I investigated (1) ontogenetic variation in bufadienolides, (2) bufadienolides from adult parotoid secretion, (3) effectiveness of bufadienolides against a terrestrial predator, and (4) effectiveness of bufadienolides against an aquatic predator. I hypothesized that B. americanuswould have a more extensive …

Changes In Glial Cell Line Derived Neurotrophic Factor And Nerve Growth Factor Expression With Development, Age, Exercise And Hypertension, Bertha C. Rebimbas-Cohen

Dissertations

Neurotrophic factors are important for neuronal growth, survival, and maintenance of cell phenotype. Glial cell line-derived neurotrophic factor (GDNF) affects sensory, autonomic and somatic motor neurons and nerve growth factor (NGF) affects sensory and sympathetic neurons. NGF and GDNF are produced by cardiac muscle and have potent effects on sensory and autonomic neuronal innervation of blood vessels. Neural innervation plays a key role in blood vessel function. Since neural innervation of blood vessels may be regulated by growth factors, we wanted to determine what changes would occur to NGF and GDNF levels with maturity, exercise and hypertension.

Changes in GDNF …

Function And Role Of Synaptotagmin Proteins In Yeast, Aaron J. Yang

Renée Crown University Honors Thesis Projects - All

In the genome of the budding yeast, Saccharomyces cerevisiae, a family of proteins is encoded that resembles the Ca2+ sensing synaptotagmins present in neuronal cells of higher eukaryotes. The synaptotagmins couple a rise in cytosolic Ca2+ with synaptic vesicle formation and release during the process of vesicular trafficking and exocytosis. This process is important in higher organisms for neurotransmitter release and signal transmission. At least a dozen synaptotagmin isoforms exist, some that are expressed outside the nervous system, suggesting that the synaptotagmin proteins might regulate membrane trafficking in a variety of different cell types. The synaptotagmin proteins in higher …

The Effects Of Local Grassland Habitat And Surrounding Landscape Composition On The Predators Of Grassland Bird Nests., Page Klug

Student Work

In agroecosystems birds use fragmented grasslands which are saturated by numerous nest predators. Multiple predator threats should increase nest predation, but predator interactions complicate relationships. I studied nest predators of Dickcissels (Spiza americana), a bird of conservation concern. I asked: (1) Does predator community explain predators documented on video? (2) What predator community best explains nesting success? (3) How does the predator community respond to habitat at multiple levels?

Insertional Polymorphisms Of Endogenous Feline Leukemia Viruses, Alfred L. Roca, William G. Nash, Joan C. Menninger, William J. Murphy, Stephen J. O'Brien

Biology Faculty Articles

The number, chromosomal distribution, and insertional polymorphisms of endogenous feline leukemia viruses (enFeLVs) were determined in four domestic cats (Burmese, Egyptian Mau, Persian, and nonbreed) using fluorescent in situ hybridization and radiation hybrid mapping. Twenty-nine distinct enFeLV loci were detected across 12 of the 18 autosomes. Each cat carried enFeLV at only 9 to 16 of the loci, and many loci were heterozygous for presence of the provirus. Thus, an average of 19 autosomal copies of enFeLV were present per cat diploid genome. Only five of the autosomal enFeLV sites were present in all four cats, and at only one …

The extent and patterns of linkage disequilibrium (LD) determine the feasibility of association studies to map genes that underlie complex traits. Here we present a comparison of the patterns of LD across four major human populations (African-American, Caucasian, Chinese, and Japanese) with a high-resolution single-nucleotide polymorphism (SNP) map covering almost the entire length of chromosomes 6, 21, and 22. We constructed metric LD maps formulated such that the units measure the extent of useful LD for association mapping. LD reaches almost twice as far in chromosome 6 as in chromosomes 21 or 22, in agreement with their differences in recombination …

Correlates Of In-Home Smoking Behavior Of Parents With Newborns, James Kyung Jo

Loma Linda University Electronic Theses, Dissertations & Projects

Secondhand smoke has been shown to have adverse health effects on young children. It is associated with various health effects such as respiratory infections, Sudden Infant Death Syndrome (SIDS), and asthma. Because of the dangers secondhand smoke poses to young children, there is a need for educating parents about the dangers of secondhand smoke as well as determining factors associated with secondhand smoke exposure among children. Understanding these factors may be first step toward developing strategies to reduce ETS exposure.

The study examined correlates of in-home smoking behavior of parents with newborns by analyzing 657 respondents who filled out the …

Because We Smile: Jonathan Swift's Enthusiastic Magnifying Glass, Jared Timothy Mink

Senior Honors Theses

Jonathan Swift (1667-1745) was intellectually before his time. His insights into the human condition reveal a belief in the not-hopeless corruption of humanity. To capture this state of the human condition, he used two key symbols: wind and machine. These two symbols represent the two sides of the dialectical argument into which Swift forces his readers. What guide should direct humanity-enthusiasm and emotional stimulation (wind) or reason and "objective" systems (the machine)? Preoccupied with these two ideas, Swift uses his scatological satires to level all of humanity. Swift forces his readers onto their knees in the mud and mire and …

Meaningful Learning: Reconciling The Tensions Between Constructivist And Environmentally Sustainable Pedagogy, Nancy Van Kannel-Ray

Dissertations

Critics of constructivism argue, in many ways correctly, that this approach to education is culturally and environmentally damaging because constructivism may not develop an understanding of the interdependence between the human community and the world in which people live. Advocates for environmentally sustainable pedagogy argue the importance of understanding patterns of thinking that allow communities to live sustainably. The purpose of this study is to resolve the tensions between the two pedagogical frameworks: constructivism and environmental sustainability.

The tensions are resolved in two ways. First, there are forms of constructivism that align in viable ways with the criteria critics argue …

Producing Pulses In The Southern Agricultural Region, Peter White, Mark Seymour, Pam Burgess, Martin Harries

Bulletins 4000 -

The development of pulses in Western Australia has undergone tremendous advances over the past 12 years.

This book, which is both comprehensive and practical, collates much of the information gathered through pulse research and commercial experience over the past 10 years and will be valuable to all pulse growers, agronomists, students and industry advisors alike. The …

Identifying Leadership: Correlations Between Introversion-Extroversion And Leadership Qualities, Tom Hinkley

Senior Honors Theses

From the beginning of time, individuals have been forced to work in groups via the circumstances they were presented with. Naturally, individuals within the groups stepped forward to take roles of leadership, guiding the rest of the group. Since then, an emphasis has been placed identifying those qualities which make successful leaders. Kouzes and Posner (1995) have identified five vital qualities of a leader: challenging the process; inspiring a shared vision; enabling others to act; modeling the way; and encouraging the heart. In an effort to gain personal insight, leader or not, an emphasis on getting to know your personality …

Increased Action Potential Firing Rates Of Layer 2/3 Pyramidal Cells In The Prefrontal Cortex Are Significantly Related To Cognitive Performance In Aged Monkeys, Yu Ming Chang, Douglas L. Rosene, Ronald J. Killiany, Lisa A. Mangiamele, Jennifer I. Luebke

Biological Sciences: Faculty Publications

The neurobiological substrates of significant age-related deficits in higher cognitive abilities mediated by the prefrontal cortex (PFC) are unknown. To address this issue, whole-cell current-clamp recordings were used to compare the intrinsic membrane and action potential (AP) firing properties of layer 2/3 pyramidal cells in PFC slices from young and aged behaviorally characterized rhesus monkeys. Most aged subjects demonstrated impaired performance in Delayed Non-Match to Sample (DNMS) task acquisition, DNMS 2 min delay and the Delayed Recognition Span task. Resting membrane potential and membrane time constant did not differ in aged relative to young cells, but input resistance was significantly …

Sara Is An Essential Positive Regulator Of Staphylococcus Epidermidis Biofilm Development, Maria A. Tormo, Miguel Marti, Jaione Valle, Adhar C. Manna

Dartmouth Scholarship

Staphylococcus epidermidis biofilm formation is associated with the production of the polysaccharide intercellular adhesin (PIA)--poly-N-acetylglucosamine polysaccharide (PNAG) by the products of the icaADBC operon. Recent evidence indicates that SarA, a central regulatory element that controls the production of Staphylococcus aureus virulence factors, is essential for the synthesis of PIA/PNAG and the ensuing biofilm development in this species. Based on the presence of a sarA homolog, we hypothesized that SarA could also be involved in the regulation of the biofilm formation process in S. epidermidis. To investigate this, we constructed nonpolar sarA deletions in two genetically unrelated S. epidermidis clinical strains, …

Identification Of A Tcpc-Tcpq Outer Membrane Complex Involved In The Biogenesis Of The Toxin-Coregulated Pilus Of Vibrio Cholerae, Niranjan Bose, Ronald K. Taylor

Dartmouth Scholarship

The toxin-coregulated pilus (TCP) of Vibrio cholerae and the soluble TcpF protein that is secreted via the TCP biogenesis apparatus are essential for intestinal colonization. The TCP biogenesis apparatus is composed of at least nine proteins but is largely uncharacterized. TcpC is an outer membrane lipoprotein required for TCP biogenesis that is a member of the secretin protein superfamily. In the present study, analysis of TcpC in a series of strains deficient in each of the TCP biogenesis proteins revealed that TcpC was absent specifically in a tcpQ mutant. TcpQ is a predicted periplasmic protein required for TCP biogenesis. Fractionation …

Fisheries Research Contract Report No. 12 - Mitigation Of The Negative Impacts On Biodiversity And Fisheries Values Of The Refurbishment Of Waroona Dam, South-Western Australia (Final Report For The Water Corporation Of Western Australia), Brett Molony, Stephen Beatty, Chris Bird, Vinh Nguyen
