Calcium : Magnesium Ratio Affects Environmental Stress Sensitivity In The Serpentine-Endemic Alyssum Inflatum (Brassicaceae), Rasoul Ghasemi, Zohreh Zare Chavoshi, Robert S. Boyd, Nishanta Rajakaruna

Biological Sciences

Plants endemic to serpentine soils are adapted to harsh environmental conditions typical of those soils, particularly, low (<1) calcium (Ca) : magnesium (Mg) ratios. We compared survival of two perennial Alyssum species native to Iran under experimental manipulations of Ca : Mg ratio, including when Ca : Mg ratio was varied under conditions of high ammonium concentration and heat stress. Alyssum inflatum is a serpentine endemic capable of nickel (Ni) hyperaccumulation, whereas A. lanceolatum is found on non-serpentine soils and is not known to hyperaccumulate Ni. We grew plants of both species under four Ca : Mg ratios (0.4, 2, 20, 40) and tested survival when plants were exposed to elevated ammonium …

Transfer Of Heavy Metals Through Terrestrial Food Webs: A Review, Jillian E. Gall, Robert Boyd, Nishanta Rajakaruna

Biological Sciences

Heavy metals are released into the environment by both anthropogenic and natural sources. Highly reactive and often toxic at low concentrations, they may enter soils and groundwater, bioaccumulate in food webs, and adversely affect biota. Heavy metals also may remain in the environment for years, posing long-term risks to life well after point sources of heavy metal pollution have been removed. In this review, we compile studies of the community-level effects of heavy metal pollution, including heavy metal transfer from soils to plants, microbes, invertebrates, and to both small and large mammals (including humans). Many factors contribute to heavy metal …

A Preliminary Survey Of The Diversity Of Soil Algae And Cyanoprokaryotes On Mafic And Ultramafic Substrates In South Africa, Arthurita Venter, Anatoliy Levanets, Stefan Siebert, Nishanta Rajakaruna

Biological Sciences

Despite a large body of work on the serpentine-substrate effect on vascular plants, little work has been undertaken to describe algal communities found on serpentine soils derived from peridotite and other ultramafic rocks. We report a preliminary study describing the occurrence of algae and cyanoprokaryotes on mafic and ultramafic substrates from South Africa. Results suggest that slope and aspect play a key role in species diversity and community composition and, although low pH, nutrients and metal content do not reduce species richness, these edaphic features also influence species composition. Further, typical soil genera such as Leptolyngbya, Microcoleus, Phormidium …

Growth And Nickel Uptake By Serpentine And Non-Serpentine Populations Of Fimbristylis Ovata (Cyperaceae) From Sri Lanka, P. K. D. Chathuranga, S. K. A. T. Dharmasena, Nishanta Rajakaruna, M.C.M. Iqbal

Biological Sciences

Compared with serpentine floras of Southeast Asia, the serpentine vegetation of Sri Lanka is impoverished in regard to serpentine endemics and nickel hyperaccumulators. All species so far documented from the serpentine outcrops of Sri Lanka also have non-serpentine populations; it is unclear whether the serpentine populations are physiologically distinct and deserve ecotypic recognition. We conducted a preliminary study to examine whether serpentine and non-serpentine populations of Fimbristylis ovata represent locally adapted ecotypes by investigating their growth and potential for nickel uptake and tolerance under greenhouse conditions. Although both populations of F. ovata showed a similar growth pattern in serpentine soil …

Vegetation Dynamics And Mesophication In Response To Conifer Encroachment Within An Ultramafic System, J. Burgess, K. Szlavecz, N. Rajakaruna, S. Lev, C. Swan

Biological Sciences

The biological, ecological, and evolutionary significance of serpentine habitats has long been recognised. We used an integrated physiochemical dataset combining plot spatial data with temporal data from tree cores to evaluate changes in soils and vegetation. Data suggest that this unique habitat is undergoing a transition, endangering local biodiversity and endemic plant species. The objective of this work was to analyse the vegetation dynamics of a xeric serpentine savanna located in the Mid-Atlantic, USA. We employed vegetation surveys of 32 10 × 15 m quadrats to obtain woody species composition, density, basal area, and developed a spatial physiochemical dataset of …

Exploring The Physiological Role Of Vibrio Fischeri Pepn, Sally L. Cello

Master's Theses

The primary contributor to Vibrio fischeri aminopeptidase activity is aminopeptidase N, PepN. Colonization assays revealed the pepN mutant strain to be deficient at forming dense aggregates and populating the host’s light organ compared to wildtype within the first 12 hours of colonization; however the mutant competed normally at 24 hours. To address the role of PepN in colonization initiation and establish additional phenotypes for the pepN mutant strain, stress response and other physiological assays were employed. Marked differences were found between pepN mutant and wildtype strain in response to salinity, acidity, and antibiotic tolerance. This study has provided a foundation …

High Potency Eugeroics-- Wake-Promoting Agents Beyond Modafinil, Joseph Yoham

Biomedical Engineering

Modafinil (Provigil) belongs to a new pharmaceutical class known as eugeroics— wake-promoting agents. Directly enhancing conductance across neuronal membranes, modafinil, amplifies presynaptic Na/Ca influx; resultant widespread depolarization of cortical interneurons could theoretically allow transient, voltage-dependent inhibition of monoamine reuptake- resembling action of conventional stimulants, minus the stereotypy, euphoria, and locomotor effects. This literature review presents a hypothesized mechanism of action, consolidates research of modafinil analogues and hybridizes a novel compound in search of a next generation molecule.

Evaluating Urban Design Strategies For Climate Change Adaptation In Los Angeles, Kerby Andrew Olsen

Master's Theses

Human interference with the Earth’s climate, through the release of greenhouse gasses (GHGs), is estimated to have already increased average statewide temperatures in California by 1.7° Fahrenheit (F), with a further 2.7°F of warming expected by mid-century. The negative impacts of increased temperatures may be especially acute in mid-latitude cities that currently enjoy a mild climate, such as Los Angeles (LA), which are projected to warm to a point that will significantly affect human health and well being. The built environment increases urban temperatures through building materials that readily absorb heat from the sun, a lack of vegetation, a lack …

Traversing Swanton Road, 18th Ed., James A. West

Academic, Government & Associated Organizational Research Resources

Situated at the northwest end of Santa Cruz County and occupying circa 30 square miles of sharply contrasted terrain, the Scott Creek Watershed concentrates within its geomorphological boundaries, at least 10-12% of California's flora, both native and introduced. Paradoxically, the use/abuse that the watershed has sustained over the past 140+ years, has not necessarily diminished the biodiversity and perhaps parallels the naturally disruptive but biologically energizing processes (fire, flooding, landslides and erosion), which have also been historically documented for the area for +60 years. This is an early edition of an extensive document by James A. West. Please visit the …

Ecotypic Differentiation Of Mid-Atlantic Quercus Species In Response To Ultramafic Soils, Jerry Burgess, Katalin Szlavecz, Nishanta Rajakaruna, Christopher Swan

Biological Sciences

Spatial heterogeneity of soil conditions combined with intraspecific variation confer site-specific edaphic tolerance, resulting in local adaptation and speciation. To understand the geoecological processes controlling community assembly of woodland tree species on serpentine and mafic soils, we investigated resource gradients and provenance (geographic area of propagule collection) as variables affecting typical representative upland oak (Quercus) species distribution. Accordingly, we conducted a year-long reciprocal transplant experiment in the greenhouse with serpentine and mafic soils, using seedlings of five oak species (Quercus marilandica, Q. stellata, Q. montana, Q. michauxii and Q. alba). All seedlings, regardless …

Sustainability In The Craft Brewing Industry: An Analysis Of Tertiary Wastewater Treatments, Jessica Uibel

Liberal Arts and Engineering Studies

In 2014, Firestone Walker began the implementation of an onsite Wastewater Treatment Plant to treat the brewery’s process wastewater. Although the secondary treatment of aerated lagoons was capable of lowering the effluent to Paso Robles discharge requirements, Firestone Walker considered investing in a tertiary treatment to reclaim water for industrial reuse in wash down, evaporative coolers, and steam generation.

The information required to determine to optimal tertiary treatment system included the effluent levels leaving the lagoons, the influent requirements for the reclamation uses, the discharge requirements from Paso Robles, and the flow rate of the process wastewater. With this information, …

Bicycle Tourism Plan For Economic Development: A Template For Rural Agricultural Towns And A Case Study For The City Of Winters, California, Marisa Rene Lee

A Preliminary Report On Escherichia Coli Strain Diversity In Cows, Alison T. Stivers

Biological Sciences

Pyroprinting is a strain typing method that relies on the simultaneous pyrosequencing of the multi-copy rRNA intergenic transcribed spacer regions of E. coli (Black, et al., 2014). These pyroprints can be used to identify the source of E. coli in the environment. Currently, Cal Poly’s Center for Applications in Biotechnology (CAB) is augmenting the existing E. coli pyroprint library. By pyroprinting the intestinal E. coli of cows, we can quantify the strain diversity present, evaluate persistence, and determine the minimum sample size required for a complete overview of the cow intestinal E. coli population. These pyroprints can then be added …
