Analysis Of Anthropogenic Effects On Topsoil Throughout The California Polytechnic State University Campus In San Luis Obispo, Brooke L. Hamilton

Earth and Soil Sciences

Soils reflect the health of a landscape, and in many cases carry the burden of anthropogenic activity, continually changing in characteristics such as pH, soil texture, soil structure, carbon:nitrogen ratios (C:N), and chemical composition. In a study sampling six different soils on the California Polytechnic State University campus in San Luis Obispo, these five soil characteristics were tested for and the results were determined. Soil samples consist of the top 5-10 cm of soil profiles, with sample sites varying according to degree of human contact; the locations the samples were taken from are as follows: (1) Walters Creek Ranch pasture, …


The Influence Of Vegetation And Landscape Position On Soil Temperature Change In A Sagebrush-Steppe Eastern Sierra Environment: Implications On Soil Taxonomy, Nathan Michael Lurie Jun 2010

The Influence Of Vegetation And Landscape Position On Soil Temperature Change In A Sagebrush-Steppe Eastern Sierra Environment: Implications On Soil Taxonomy, Nathan Michael Lurie

Earth and Soil Sciences

Soil temperature is a parameter that has been studied for a considerable time and from many different perspectives. However, relatively few studies have been conducted for taxonomic purposes and fewer still have focused on how changes in soil temperature related to global climate change may affect soil taxonomy. Soil temperature regimes are used to subdivide soils with similar properties that exist in dissimilar climate zones requiring different management practices depending on intended use. Seven sites with variable surficial features were used for this study within a cohesive sagebrush-steppe Eastern Sierra glacial moraine landform. Soil temperature was measured once a month …

A Comparison Of Costs And Returns For Organic And Conventional Cabernet Sauvignon Grape Production In San Luis Obispo County, Amanda N. Johansen

Agribusiness

This study examined the differences in costs and profitability for established conventional and organic Cabernet Sauvignon vineyards in the Edna Valley region of San Luis Obispo County, California. The study used a partial budgeting approach to compare cost and profitability for established vineyards for 2009, and thus ignored transition costs. Data were obtained from UC Davis cost studies for organic and conventional grape production in other regions of California in previous years. Adjustments made to these costs to account for changes in input use, input costs and grape prices in San Luis Obispo County during the 2009 growing season.

Research in the corrosion of orthopaedic implants is a growing research field where implants have been known to show adverse effects in patients who have encountered the unfortunate dissolution of their implants due to corrosion. Once corrosion begins within the body, many adverse biological reactions can occur such as late on-set infections resulting in severe health complications. The focus of this research is specifically related to the problem of late on-set infections caused by localized corrosion of orthopaedic implants. In medical …


The Significance Of The Male Display During Male-Male Interactions In Guppies (Poecilia Reticulata), Rebecca Nuffer, Samantha M. Alburn Jun 2010

The Significance Of The Male Display During Male-Male Interactions In Guppies (Poecilia Reticulata), Rebecca Nuffer, Samantha M. Alburn

Biological Sciences

Guppies, Poecilia reticulata, are a model species for studies of female preference based on male courtship displays; however, males also display to each other in an aggressive context, and little attention has been paid to the role of male-male displays. The display involves a male positioning his body in front or to the side of another male, arching his body, and quivering with his dorsal fin splayed. To understand what behaviors elicit a male display, we assigned individual males a dominance status. We then examined the relationship between dominance status and the number of displays delivered and received. By …


Body Size And Social Dominance Influence Breeding Dispersal In Male Pachydiplax Longipennis (Odonata), Shannon Mccauley Jun 2010

Body Size And Social Dominance Influence Breeding Dispersal In Male Pachydiplax Longipennis (Odonata), Shannon Mccauley

Biological Sciences

1. Dispersal behaviour can be affected by an individual's phenotype, by the environmental or social context they experience, and by interactions between these factors. Differential dispersal propensities between individuals may also be an important modifier of functional connectivity between populations. To assess how a key trait, body size, affected both social interactions and dispersal behaviour, this study examined the relationship between body size, antagonistic interactions, and breeding dispersal in male dragonflies (Pachydiplax longipennis) across a seasonal decline in adult body size. 2. During a seasonal peak in male body size in this study, dispersers were smaller than non-dispersers. Later in …


North American Montane Red Foxes: Expansion, Fragmentation, And The Origin Of The Sacramento Valley Red Fox, Benjamin N. Sacks, Mark J. Statham, John D. Perrine, Samantha M. Wisely, Keith B. Aubry Jun 2010

North American Montane Red Foxes: Expansion, Fragmentation, And The Origin Of The Sacramento Valley Red Fox, Benjamin N. Sacks, Mark J. Statham, John D. Perrine, Samantha M. Wisely, Keith B. Aubry

Biological Sciences

Most native red foxes (Vulpes vulpes) in the western contiguous United States appear to be climatically restricted to colder regions in the major mountain ranges and, in some areas, have suffered precipitous declines in abundance that may be linked to warming trends. However, another population of unknown origin has occurred in arid habitats in the Sacramento Valley of California well outside this narrow bioclimatic niche since at least 1880. If native, this population would be ecologically distinct among indigenous North American red foxes. We used mitochondrial and microsatellite markers from historical and modern samples (modes: 1910–1930 and 2000–2008, …

This paper will present the development and assessment of a PCB layout and manufacturing laboratory module that has been used in introductory electric circuits laboratories for EE and non-EE majors. The feasibility of integrating the new PCB layout and manufacturing module into the electric circuit course will be …


The Evolution Of Seeds, Ada Linkies, Kai Graeber, Charles A. Knight, Gerhard Leubner-Metzger Jun 2010

The Evolution Of Seeds, Ada Linkies, Kai Graeber, Charles A. Knight, Gerhard Leubner-Metzger

Biological Sciences

The evolution of the seed represents a remarkable life-history transition for photosynthetic organisms. Here, we review the recent literature and historical understanding of how and why seeds evolved. Answering the 'how' question involves a detailed understanding of the developmental morphology and anatomy of seeds, as well as the genetic programs that determine seed size. We complement this with a special emphasis on the evolution of dormancy, the characteristic of seeds that allows for long 'distance' time travel. Answering the 'why' question involves proposed hypotheses of how natural selection has operated to favor the seed life-history phenomenon. The recent flurry of …

Mapping The Medical Device Development Process, Scott T. Ham Jun 2010

Mapping The Medical Device Development Process, Scott T. Ham

Industrial Technology and Packaging

This project examined the use of process mapping as a tool to show the process of developing medical devices from a broad perspective that includes research, innovation, development, regulation, and marketing. The medical device development cycle, on a broad scope, is not well defined. The lack of a universal language with which to describe this process has made it difficult to understand and communicate. In this project, data was collected from peer-reviewed sources, summarized in a literature review, drawn out by hand into a series of lower-level process maps and finally assembled into a single process map. This project is …
