Botanist In Death Valley, Stanley L. Welsh

Books by Faculty of the Monte L. Bean Life Science Museum

Abstract

This book details the author’s trips to Death Valley, along with general ecological information about the region. Explorations by other natural historians are also recounted. Death Valley and its surrounding mountain ranges are stark and appear to lack vegetative cover, but that appearance is deceiving. The ranges and valley support a great diversity of living things, both plants and animals. Pages 10–17 contain photographs of various landscapes. Pages 18–20 list the plant species collected in Death Valley, 1970–1983. Voucher specimens are available for study at Stanley L. Welsh Herbarium, Brigham Young University.

A Better Balancing: Reconsidering Pre-Conviction Dna Extraction From Federal Arrestees, Joy Radice

Scholarly Works

Federal law mandates the collection of a biological sample from anyone arrested by federal authorities or facing federal charges, regardless of the charge. The FBI then creates a DNA profile from the sample and enters that profile into the Combined DNA Index System (“CODIS”), a national database through which law enforcement matches individuals and crime scene DNA evidence.

Part I of the essay briefly reviews the federal statute that authorizes pre-conviction DNA extraction and the Fourth Amendment principles that underlie the current constitutional challenges to it. Part II identifies the various, and sometimes competing, rationales offered to justify the constitutionality …

Influence Of Soil Microorganisms On Plant Growth And Fitness, Benjamin Jayne

Electronic Theses and Dissertations

Most terrestrial plants benefit from symbiosis with soil microorganisms. Symbiotic bacteria and fungi have wide-ranging effects on host plants, including improved nutrition, disease resistance, and drought tolerance. Association with Arbuscular Mycorrhizal Fungi (AMF) can enhance growth and protect plants from environmental stressors while they share products of photosynthesis with the resident fungi. Scores of studies indicate that mycorrhizal plants are more resistant to drought stress than their non-mycorrhizal counterparts. Use of microbes as a plant and soil supplement in home gardens represents a sustainable alternative to resource-intensive inputs and may allow for reduced water use. I investigated the effects of …

A Fast-Slow Analysis Of The Dynamics Of Rem Sleep, Victoria Booth, Cecilia G. Diniz Behn

Math Faculty Publications

Waking and sleep states are regulated by the coordinated activity of a number of neuronal population in the brainstem and hypothalamus whose synaptic interactions compose a sleep-wake regulatory network. Physiologically based mathematical models of the sleep-wake regulatory network contain mechanisms operating on multiple time scales including relatively fast synaptic-based interations between neuronal populations, and much slower homeostatic and circadian processes that modulate sleep-wake temporal patterning. In this study, we exploit the naturally arising slow time scale of the homeostatic sleep drive in a reduced sleep-wake regulatory network model to utilize fast-slow analysis to investigate the dynamics of rapid eye movement …

Evaluation Of Critical Parameters Of Low Level Laser Irradiation On Human Osteoblast Cell Proliferation And Differentiation, Samuel Dean Waddoups

Student Theses, Dissertations and Capstones

Abstract

Orthodontic tooth movement is a biological response to a mechanical force. One of the challenges in orthodontics is obtaining desired tooth movement during treatment. Accelerating tooth movement and decreasing demands on anchorage can reduce treatment times and overall satisfaction for patient and doctor. Low-level laser therapy (LLLT) is emerging as a technology that may decrease orthodontic treatment time. Many in vitro and in vivo studies have reported the effects of low level lasers at random time points and energy densities. None of the studies have optimized the dose required for osteoblast proliferation and differentiation. The purpose of this study …

Nocturnal Activity Of Nesting Shrubland And Grassland Passerines, Christy Slay, Kevin Ellison, C.A. Ribic, Kimberly Smith, Carolyn Schmitz

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Nocturnal behaviors and sleep patterns of nesting passerines remain largely undocumented in the field and are important to understanding responses to environmental pressures such as predation. We used nocturnal video recordings to describe activity and quantify behaviors of females with nestlings of four shrub land bird species and three grassland bird species (n = 19 nests). Among the shrubland birds, Blue-winged Warbler (Vermivora pinus), Prairie Warbler (Setophaga discolor), and Indigo Bunting (Passerina cyanea) returned to the nest for the night at the same time, around sunset. Among the grassland birds, Eastern Meadowlark ( …

Ducks And Passerines Nesting In Northern Mixed-Grass Prairie Treated With Fire, Todd A. Grant, Terry L. Shaffer, Elizabeth M. Madden, Gordon B. Berkey

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Prescribed fire is an important, ecology-driven tool for restoration of grassland systems. However, prescribed fire remains controversial for some grassland managers because of reported reductions in bird use of recently burned grasslands. Few studies have evaluated effects of fire on grassland bird populations in the northern mixed-grass prairie region. Fewer studies yet have examined the influence of fire on nest density or survival. In our review, we found no studies that simultaneously examined effects of fire on duck and passerine nesting. During 1998–2003, we examined effects of prescribed fire on the density of upland-nesting ducks and passerines nesting in north-central …

An At Mutational Bias In The Tiny Gc-Rich Endosymbiont Genome Of Hodgkinia, James T. Van Leuven, John Mccutcheon

Biological Sciences Faculty Publications

The fractional guanine + cytosine (GC) contents of sequenced bacterial genomes range from 13% to 75%. Despite several decades of research aimed at understanding this wide variation, the forces controlling GC content are not well understood. Recent work has suggested that a universal adenine + thymine (AT) mutational bias exists in all bacteria and that the elevated GC contents found in some bacterial genomes is due to genome-wide selection for increased GC content. These results are generally consistent with the low GC contents observed in most strict endosymbiotic bacterial genomes, where the loss of DNA repair mechanisms combined with the …

A New Forest Fire Paradigm: The Need For High-Severity Fires, Monica L. Bond, Rodney B. Siegel, Richard L. Hutto, Victoria A. Saab, Stephen A. Shunk

Biological Sciences Faculty Publications

Forest fires, particularly those that burn at mixed and high severity (collectively called ‘severe’), have been traditionally perceived as catastrophic events, directing public attention and immense forest management budgets toward fire prevention and suppression. These fires may indeed be catastrophic when measured by losses of human lives and property. However, severe fires in wildland areas are both natural and necessary to maintain the integrity of dynamic, disturbance-adapted forest systems. We propose a change in the current paradigm—which holds that severe forest fires are always harmful—to a new one that embraces their ecological necessity.

The Curious Case Of Arenavirus Entry, And Its Inhibition, Jack H. Nunberg, Joanne York

Biological Sciences Faculty Publications

Arenaviruses comprise a diverse family of enveloped negative-strand RNA viruses that are endemic to specific rodent hosts worldwide. Several arenaviruses cause severe hemorrhagic fevers in humans, including Junin and Machupo viruses in South America and Lassa fever virus in western Africa. Arenavirus entry into the host cell is mediated by the envelope glycoprotein complex, GPC. The virion is endocytosed on binding to a cell-surface receptor, and membrane fusion is initiated in response to physiological acidification of the endosome. As with other class I virus fusion proteins, GPC-mediated membrane fusion is promoted through a regulated sequence of conformational changes leading to …

New Combinations For The Montana Flora, Peter Lesica

University of Montana Herbarium Publications

Three new combinations are proposed. Agoseris carnea Rydb. and A. lackschewitzii Douglass M. Hend. & R.K. Moseley are considered the same entity and have been subsumed into A. aurantiaca (Hook.) Greene as a new infraspecific taxon. Artemisia lindleyana Besser has been treated as a distinct species, but a recent treatment subsumes it into A. ludoviciana Nutt. Similarities between the two entities are undeniable, but morphological and ecological differences lead me to believe that the former is best considered as a subspecies of the latter. Recent transfer of many New World asters into Symphyotrichum requires a new combination for Aster cusickii …

An Exploratory Case Study Of Upper Elementary And Middle Level Science Instruction Impacting Traditionally Underserved Students, Lucinda Howe

Electronic Theses and Dissertations

This is an exploratory case study looking at the practices in one Colorado K-8 school that had students performing at or above the 75th percentile on the eighth grade Science Colorado Assessment of Student Progress (CSAP) in 2009. This study attempted to answer the question: What are the instructional choices, classroom environments, interventions, and school practices in place in one K-8 school that is supporting traditionally underserved populations of students in the learning of science? This school appears to be meeting the needs of their traditionally underserved students as evidenced by the percent of students in these populations at this …

Aladdin's Magic Lamp: Developing Methods For Calibration And Geolocation Accuracy Assessment Of The Dmsp Ols, Benjamin Taylor Tuttle

Electronic Theses and Dissertations

Nighttime satellite imagery from the Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS) has a unique capability to observe nocturnal light emissions from sources including cities, wild fires, and gas flares. Data from the DMSP OLS is used in a wide range of studies including mapping urban areas, estimating informal economies, and estimating urban populations. Given the extensive and increasing list of applications a repeatable method for assessing geolocation accuracy, performing inter-calibration, and defining the minimum detectable brightness would be beneficial. An array of portable lights was designed and taken to multiple field sites known to have no other …

A Hydrodynamic Method For Measuring Aqueous Nanoparticle Surface Interactions, Kellen John Sorauf

Electronic Theses and Dissertations

The objectives of this research dissertation were to develop and present novel analytical methods for the quantification of surface binding interactions between aqueous nanoparticles and water-soluble organic solutes. Quantification of nanoparticle surface interactions are presented in this work as association constants where the solutes have interacted with the surface of the nanoparticles. By understanding these nanoparticle-solute interactions, in part through association constants, the scientific community will better understand how organic drugs and nanomaterials interact in the environment, as well as to understand their eventual environmental fate. The biological community, pharmaceutical, and consumer product industries also have vested interests in nanoparticle-drug …

School Readiness For Young Migrant Children: The Challenge And The Outlook, Smita Mathur

Selected Works

There is evidence that children from families of migrant workers are among the most disadvantaged in term of early academic achievement. Yet there are insufficient resources allocated to research exploring the reasons that existing preschool programs are not effective in closing the gap between migrant children and other groups of children in the USA. There are some Head Start programs that migrant children have access to, but many of them offer simply care-giving functions and offer little opportunities for enrichment activities for children in preschool. This paper explores some of the barriers to engaging the preschool child effectively in educational …
