Poised To Prosper? A Cross-System Comparison Of Climate Change Effects On Native And Non-Native Species Performance, Cascade J. B. Sorte, Ines Ibáñez, Dana M. Blumenthal, Nicole A. Molinari, Luke P. Miller, Edwin D. Grosholz, Jeffrey M. Diez, Carla M. D'Antonio, Julian D. Olden, Sierra J. Jones, Jeffrey S. Dukes

Faculty Publications, Biological Sciences

Climate change and biological invasions are primary threats to global biodiversity that may interact in the future. To date, the hypothesis that climate change will favour non-native species has been examined exclusively through local comparisons of single or few species. Here, we take a meta-analytical approach to broadly evaluate whether non-native species are poised to respond more positively than native species to future climatic conditions. We compiled a database of studies in aquatic and terrestrial ecosystems that reported performance measures of non-native (157 species) and co-occurring native species (204 species) under different temperature, CO2 and precipitation conditions. Our analyses revealed …

Searching Mindfully: Are Libraries Up To The Challenge Of Competing With Google Books?, Amrita Dhawan

Library Philosophy and Practice (e-journal)

Traditional research tools used by libraries, such as encyclopedias and catalogs were created in an age of print and information scarcity. They have not kept up with changes in the information world, including an abundance of online information in different formats and the rise of interdisciplinary topics which attempt to solve ‘real world’ messy problems and not traditional theoretical questions. The traditional tools rest on collaboration between OCLC, LOC, private aggregators, librarians and faculty. The search results they deliver offer excessive information with very little guidance on how to systematically sift through them. This makes the research process harder and …

The Role Of Canids In Ritual And Domestic Contexts: New Ancient Dna Insights From Complex Hunter-Gatherer Sites In Prehistoric Central California, Alan M. Leventhal, Brian F. Byrd, Anna Cornellas, Jelmer W. Eerkens, Jeffrey Rosenthal, Tim R. Carpenter, Jennifer A. Leonard

Faculty Publications, Anthropology

This study explores the interrelationship between the genus Canis and hunter–gatherers through a case study of prehistoric Native Americans in the San Francisco Bay-Sacramento Delta area. A distinctive aspect of the region's prehistoric record is the interment of canids, variously classified as coyotes, dogs, and wolves. Since these species are difficult to distinguish based solely on morphology, ancient DNA analysis was employed to distinguish species. The DNA study results, the first on canids from archaeological sites in California, are entirely represented by domesticated dogs (including both interments and disarticulated samples from midden deposits). These results, buttressed by stable isotope analyses, …

Productive Resources In Students’ Ideas About Energy: An Alternative Analysis Of Watts’ Original Interview Transcripts, Benedikt W. Harrer, Virginia J. Flood, Michael C. Wittmann

Faculty Publications

For over 30 years, researchers have investigated students’ ideas about energy with the intent of reforming instructional practice. In this pursuit, Watts contributed an influential study with his 1983 paper “Some alternative views of energy” [Phys. Educ. 18, 213 (1983)]. Watts’ “alternative frameworks” continue to be used for categorizing students’ non-normative ideas about energy. Using a resources framework, we propose an alternate analysis of student responses from Watts’ interviews. In our analysis, we show how students’ activated resources about energy are disciplinarily productive. We suggest that fostering seeds of scientific understandings in students’ ideas about energy may play an important …

The Role Of Elevation And Soil Chemistry In The Distribution And Ion Accumulation Of Floral Morphs Of Streptanthus Polygaloides Gray (Brassicaceae), A Californian Nickel Hyperaccumulator, N Pope, M Fong, R Boyd, N Rajakaruna

Faculty Publications, Biological Sciences

Background: The flora of serpentine/ultramafic soils provides an excellent model system for the study of natural selection in plant populations. Streptanthus polygaloides is a nickel hyperaccumulator that is endemic to serpentine soils in the Sierra Nevada of California, and has four floral morphs (yellow, purple, yellow-to-purple and undulate). Aims: We investigate three hypotheses: (1) the purple morph occurs in colder, wetter climates than the yellow morph; (2) tissue–soil ionic relationships differ among morphs; and (3) morphs occur on soils with differing elemental concentrations. Methods: We queried herbarium records to investigate patterns of occurrence among the yellow and purple floral morphs, …

Brief Communication: Evolution Of A Specific O Allele (O1vg542a) Supports Unique Ancestry Of Native Americans, Fernando A. Villanea, Deborah A. Bolnick, Cara Monroe, Rosita Worl, Rosemary Cambra, Alan M. Leventhal, Brian M. Kemp

Faculty Publications, Anthropology

In this study, we explore the geographic and temporal distribution of a unique variant of the O blood group allele called O1vG542A, which has been shown to be shared among Native Americans but is rare in other populations. O1vG542A was previously reported in Native American populations in Mesoamerica and South America, and has been proposed as an ancestry informative marker. We investigated whether this allele is also found in the Tlingit and Haida, two contemporary indigenous populations from Alaska, and a pre-Columbian population from California. If O1vG542A is present in Na-Dene speakers (i.e., Tlingits), it would indicate that Na-Dene speaking …

Occupational Engagement And Health In Older South Asian Immigrants, Sheama R. Krishnagiri, Erin Fuller, Lesley Ruda, Sadhna Diwan

Faculty Publications

The purpose of this study was to investigate the elements that shape how healthy active South Asian elder immigrants engage in daily activities to maintain their health. A descriptive grounded theory approach was employed using semi-structured interviews and a daily activity chart. Convenience sampling was used to recruit 12 South Asian elders, 7 males and 5 females, who immigrated after retirement to the South San Francisco Bay area. Open, axial, and selective coding of the transcribed data led to two broad themes, control and interdependence. These themes may be viewed as dynamic and interconnected forces that shape and determine the …

Students Talk About Energy In Project- Based Inquiry Science, Benedikt W. Harrer, Virginia J. Flood, Michael C. Wittmann

Faculty Publications

We examine the types of emergent language eighth grade students in rural Maine middle schools use when they discuss energy in their first experiences with Project-Based Inquiry Science: Energy, a research-based curriculum that uses a specific language for talking about energy. By comparative analysis of the language used by the curriculum materials to students’ language, we find that students’ talk is at times more aligned with a Stores and Transfer model of energy than the Forms model supported by the curriculum.

Characterization Of Hydride-Based Silica And Diamond Hydride Stationary Phases, Nima C. Parmar

Master's Theses

Aqueous normal phase chromatography possesses characteristics of both normal phase (NP) and also reverse phase (RP) chromatography. It can retain polar as well as non-polar compounds by carefully selecting the concentration ratio of organic solvent to water in the mobile phase. Silica hydride columns contain only a small percentage of silanol groups which are polar in nature and have an effect on the separation process. Diamond hydride columns consist of a small amount (~2%) of carbon chemically bonded to a silica hydride surface.

This research work characterized both hydride-based silica and diamond hydride stationary phases under isocratic and gradient conditions. …

Ecotourism As A Tool For Conservation Of Coast Redwoods In Santa Cruz County, California, Chandana Rao

Master's Theses

According to the World Tourism Organization, ecotourism is the fastest growing segment of the tourism industry, generating $300 billion in annual revenue. Ecotourism aims to control the damaging effects of conventional mass tourism and tries to overcome tourism's environmental and socio-cultural challenges. In an ideal situation, ecotourism can help conserve fragile biodiversity, build ties between parks and communities, and increase awareness of environmental issues; it also includes a profit impetus for businesses.

This research was conducted to evaluate the potential for developing ecotourism as a conservation tool in the four redwoods state parks of Santa Cruz County. The study assessed …

Natural Recovery Of Second-Growth Coast Redwood Stands In The Santa Cruz Mountains, Jeffrey M. Sinclair

Master's Theses

The natural recovery of coast redwood forests following a logging event is not fully understood. Recent studies, in the redwood central range, have found that un-restored and unmanaged second-growth forest stands can begin to recover and exhibit characteristics of old-growth stands within 100 years or less. The goal of this study was to determine if redwood stands in their southern range are recovering naturally. A total of 160 sample plots were selected randomly within old-growth and second-growth study sites. The data collected included stand density, tree size structure, canopy cover, species diversity, and species composition. Special habitat features were analyzed …

A Girlhood Of Myth, Dreams, And Trauma: Redefining The Asian North American Female Bildungsroman, Danielle Brianna Crawford

Master's Theses

This thesis examines the use of myth, dreams, and historical trauma within the genre of the Asian North American female bildungsroman. In an attempt to redefine the contested genre of the ethnic bildungsroman, this study analyzes three novels by Asian American and Asian Canadian female authors: Cecilia Manguerra Brainard's When the Rainbow Goddess Wept (1991), Joy Kogawa's Obasan (1981), and Lan Cao's Monkey Bridge (1997). Each of these novels is an ethnic bildungsroman that highlights the identity formation of a female protagonist in the midst of historical trauma. This study focuses on the ways in which these texts resist the …

Immobilization Of Rhodococcus Erythropolis As A Potential Treatment For Atherosclerosis, Srikanth Darbha

Master's Theses

Cardiovascular disease is the leading cause of death in the United States and isprimarily due to hypercholesterolemia. The novel approach of combatting atherosclerosis presented in this research entails delivery of microencapsulated Rhodococcus erythropolis immobilized in biodegradable alginate-based microcapsules and utilizing the bacterium's cholesterol oxidase enzyme pathway to degrade cholesterol from intermediate-stage arterial plaque. The bacterial growth medium was optimized using Taguchi design methods to enable growth characterizations hindered by biosurfactant by-product. Methodologies for extraction and quantification of biosurfactant and cholesterol were developed and conducted simultaneous to bacterial growth assessment. Bacteria were encapsulated using atomization (850±50 μm) and inkjet bioprinting (32±5 …

An Ecological Assessment Of Insect Diversity At Organic Central Coast Vegetable Farms On Two Spatial Scales, Emily Musgrave

Master's Theses

Modern industrial agriculture is the principal cause of anthropogenic land use changes for terrestrial ecosystems. Approximately 40% of the planet's land surface, or half of the habitable area, is now composed of agricultural landscapes. The simplification and industrialization of agriculture are the biggest drivers of global biodiversity loss, especially on Californian's Central Coast. Diversified organic agriculture, however, may offer some refuge for non-crop species. In this study we analyzed insect and plant biodiversity on and adjacent to organic vegetable farms on the Central Coast of California at two spatial scales, the landscape-scale and a smaller within-farm scale. At the landscape-scale, …

Funding Sources Of Impactful And Transformative Research, Barrett Anderson

Master's Theses

Understanding how the most important scientific articles have been funded can help inform and improve future funding decisions. Importance is here defined as science that, in the metaphor of the tree of knowledge, plays a structurally significant role (e.g., creates new branches of knowledge or transforms existing ones). The structural significance of articles is broken down into two submeasures: citation count and "generativity" (a novel measure defined as being highly cited and also leading to a comparatively large number of other highly cited articles). Generativity is an attempt to provide a quantitative operationalization that should correlate with transformativeness, a concept …

Farms On Campus: Strong Stakeholder Support For An Educational Garden At A Non-Land-Grant University, Gina M. Bacigalupi

Master's Theses

University farms and gardens are increasingly seen as effective tools for learning a variety of academic subjects and as resources that allow users to connect experientially to nature. Most existing university farms, however, are found at resource-rich land-grant universities. This research evaluated stakeholder interest and willingness-to-pay in money, time, and labor for a proposed educational farm at a public, urban, non-land-grant university through an online survey of over 400 members of the California State University East Bay, Concord Campus community. Overall, support for an educational farm at this site was high amongst all stakeholder groups. Students and stakeholders who hold …

Intra-Annual Changes In Population Parameters As Indicators Of Humpback Whale (Megaptera Novaeangliae) Migratory Behavior, Casey Clark

Master's Theses

Many techniques used to study animal migrations rely on observations of specific animals, which provide valuable information about individuals studied but do not capture population variability. By examining changes in population parameters, researchers may gain a better understanding of migratory behaviors. In this study, intra-annual changes in population parameters were used to study migratory behaviors of humpback whales off central California in 2011/2012. Data were compared with a historic dataset from 2004/2005. Parameters measured included sex ratio, pregnancy rate, mitochondrial DNA haplotype frequencies and mean δ13C and δ15N values. Weighted moving averages of the sex ratio were moderately effective at …

Theoretical And Experimental Exploration Of Gill Remodeling In Gambusia Affinis, Barbara Tess Douglas

Master's Theses

In this thesis, the phenomenon of gill remodeling discovered in several species of fish is explored. Gill remodeling is achieved through an increase or decrease in cells within the interlamellar space, termed the interlamellar cell mass (ILCM). The effect of the ILCM on flow is explored using a theoretical model gill section. The model gill section was compared in three states: full ILCM, half ILCM, and clear (no ILCM). Differences in surface area, total flow, flow velocities, oxygen uptake, and available oxygen were compared between the three conditions. All parameters were distinctly larger for the model without the ILCM indicating …

Western Burrowing Owl Predation In An Urban Setting In California: Do California Ground Squirrel Calls Reduce Risk?, Lisa Anne Henderson

Master's Theses

Western burrowing owls are found in ground squirrel burrows throughout the urbanized landscape of the South San Francisco bay area, where they are threatened by habitat loss and degradation, prey limitation and predation. Previous research has characterized effects of habitat loss and prey-base limitations on owls, but the interplay between ground squirrels, owls and their predators has not yet been studied. The objective of this study was to assess the rate and types of predation interactions faced by Western burrowing owls and the extent to which California ground squirrels help burrowing owls reduce risk through alarm calling at Moffett Federal …

Amphibian Mortality On Roads: A Case Study In Santa Cruz Long-Toed Salamander Habitat, Michael Thomas Hobbs

Master's Theses

Amphibian populations have been declining at higher rates than bird and mammal populations. Agriculture, urbanization, including roads, and resource extraction continue to put pressure on all species. Roads in particular, are major sources of mortality. The Santa Cruz long-toed salamander (Ambystoma macrodactylum croceum), one of the most critically endangered species in the US, is one amphibian that is declining as a result of anthropogenic impacts, especially habitat loss and fragmentation due to urban development. Migration across roads puts these salamanders at risk from road-related death. This thesis quantified the rate of road mortality to these salamanders and other common amphibians …

California Glacial Till And The Glaciated Valley Landsystem: Engineering Classification And Properties, Matthew Mark Lattin

Master's Theses

The engineering characteristics of glacial tills in the Sierra Nevada are difficult to determine due to the depositional nature of the material; however, testing methods unique to these dense materials can be utilized to obtain good engineering data. A literature review was conducted to determine testing methods and recommendations for engineering in glacial till. Further literature review revealed a significant amount of glacial deposits mapped by the USGS and CGS in the Sierra Nevada geomorphic province in California. Sierra Nevada glacial till field and lab data were obtained from Taber Consultants along with samples for further testing. Consequently, four significant …

Benthic Invertebrate Response To Habitat Complexity In South Bay Salt Ponds, Jessica Louise Murphey

Master's Theses

Wetlands are unique ecosystems that support specific flora, fauna, hydrology, and geology. These ecosystems increase groundwater availability, improve water quality, decrease flood water impacts, and help decrease shoreline erosion. In the south San Francisco Bay, the South Bay Salt Pond Restoration Project is restoring over 6,000 hectares of former salt ponds to tidal marshes and managed pond habitats. These habitats will support endangered species as well as migratory birds, diving ducks, invertebrates, and algal species. Benthic invertebrates are a vital piece of the South Bay food web as they provide the sustenance for other invertebrates, fish, shorebirds, and waterfowl. Improving …

Metabolic Network Construction Based On The Genome Of The Marine Diatom Thalassiosira Pseudonana And The Analysis Of Genome-Wide Transcriptome Data To Investigate Triacylglyceride Accumulation, Karen Parker

Master's Theses

Algal lipids called triacylglycerols (TAGs) are essential compounds in marine ecology and are also used as the basis for commercial production of algal biofuels and omega-3 nutraceuticals. The goal of this thesis was to elucidate the biochemical processes associated with algal lipid accumulation in diatoms under different environmental conditions. The approach made use of the Mock et al. whole genome tiling microarray gene expression database for Thalassiosira pseudonana and gene annotations derived from the whole genome sequencing work of Armbrust et al. The analytical approach used bioinformatic tools, including Stanford Research Institute's (SRI) BioCyc Pathway tool and the Joint Genome …

Local Adaptation Of Two Cryptic Species, Lasthenia Californica And Lasthenia Gracilis, To Distinct Regions Within A Serpentine Outcrop, Teri Barry

Master's Theses

Intraspecific variation providing tolerance to specific edaphic conditions may contribute to population differentiation, speciation, and species coexistence. This process is often examined using reciprocal transplant experiments of closely related species in contrasting edaphic conditions. The two cryptic species Lasthenia californica and L. gracilis occur on a serpentine outcrop in parapatry at Jasper Ridge Biological Preserve. I hypothesized that each species would demonstrate greater fitness in its home range. A reciprocal transplant experiment was conducted in the field to determine home site advantage. Seedlings from each species were planted in both home ranges and in the transition zone where both species …
